Chapter 1456: Blocking Door Coffin Shocks All Realms

In Yin State, Tai Yi meditated within the black mist. As his eyes flickered, the surrounding void collapsed, spreading for an unknown number of miles.

"The Coffin that Blocks the Door..."

In his long life, vague clues suggested he had encountered these words before.

At this moment, the portal ahead was unstable, golden cracks roared, and energy from the Great Underworld constantly overflowed. This place had already become an incredibly terrifying desolate land.

In this area now, no one except a few ultimate beings could remain; otherwise, they would instantly turn into a pool of black blood, dying without a trace.

The direct disciples of the ultimate beings were all top-tier powerful figures in the Yang Realm. However, after depositing the rare treasures and other materials used to break open the door, they quickly fled. They couldn't even stand there and had to remain outside Yin State.

"I have some impression!" Tai Yi's expression became solemn at that moment.

His expression shifted, and deep within his eyes, scenes from his youth appeared, evoking a sense of nostalgia.

He too had been young, once vibrant and righteous, walking the mortal world, becoming the protagonist of the Yang Realm in that era.

Later, he changed. To survive and grow stronger, he became increasingly cold and ruthless, viewing all life in the world as insignificant ants.

"My grandmaster... once mentioned it!"

At this moment, Tai Yi's expression completely changed. He finally remembered when he had encountered those words: it was during his youth, truly too long ago.

What kind of being was he?

Tai Yi did not originally belong to this epoch. He had escaped the great catastrophe of the previous epoch, lay dormant in the ruins of the Chaos Sea, and then recovered.

This ancient life form once belonged to a vanished world!

Because he had lived for too long, he could not retain all his memories; some insignificant ones would be sealed or directly erased.

The path of evolution has no end. Any powerful being could realize that during life transformation, if one's mind was pure and had fewer distracting thoughts, merging with the Grand Dao chains and transforming would be relatively easier.

Such ancient beings, to maintain an innocent heart, would generally sever many useless trivial memories.

And now, he had uncovered a sealed old memory, yet was chilled to the bone by it.

In these trivial memories from his youth, fragments of such a terrifying major event were actually buried!

At this moment, everyone saw his expression and heard his words, all realizing that this matter was very serious and likely extremely terrifying.

"The Coffin that Blocks the Door... this matter is very ancient, very desolate, once filled with blood and tears, concerning the life and death of everyone in the world."

Tai Yi spoke calmly.

Just this short statement immediately made everyone feel a sense of heaviness.

Everyone turned their heads and, through the crack in the door, looked at the stone coffin locked there by the Grand Dao chains of the four realms.

In an instant, everyone was overwhelmed by a sense of solemn tragedy, as if they had witnessed a desolate past event, which weighed heavily on their hearts.

"My grand-ancestor, in the previous epoch, was almost invincible, both in heaven and on earth. Yet, when he mentioned that person and that coffin, he spoke with reverence and awe."

Just a single sentence made the expressions of several ultimate beings change, feeling as if a mountain was pressing down on them.

The stone coffin became even more mysterious and unfathomable in their eyes, seeming to evoke a sense of desolation.

"My grand-ancestor said that not only our human race, but almost all races in the world, were on the verge of extinction. If not for someone blocking the door with a coffin, there would be no living beings left in the world."

The old tale was brief, just a few words, yet it made one vaguely sense the atmosphere of that era: a bleeding world where all races faced annihilation.

Someone carried a coffin to block the door, stemming the great catastrophe and preserving the world.

"The Coffin that Blocks the Door not only saved our Yang Realm but also other worlds. My grand-ancestor mentioned that all the great realms in the heavens were affected. Without intervention, they would all be corroded by the blood flowing down from the sky. The world would turn scarlet, all things would perish, all races would wither away, and no life would remain."

This was the old memory Tai Yi provided, very concise, with no more detailed information.

However, the several ultimate beings fell silent. They remained silent for a long time, sensing the horror of that era and its solemn tragedy: bleeding heavens where all realms were destined to become dead lands, with no trace of life remaining.

"Who was that person?" asked the master of the Black Blood Institute.

"It should be related to First Mountain," Tai Yi replied.

Back then, he was still young, and his grand-ancestor had not said much more. However, based on later clues, he believed it was related to First Mountain.

As soon as these words were spoken, many people's pupils constricted. They couldn't help but feel wary; the so-called First Mountain was truly not named casually, holding all sorts of peculiarities.

Upon careful thought, that place was extremely terrifying, holding too many secrets.

"The origin of those human skins is quite strange, very eerie," someone spoke.

Numbers Nine, Six, Three, Two, and others from First Mountain had all appeared in the world before. They were very eerie and anomalous, considered to be sequence beings, from one to nine, with at least nine of them.

Some also said that it was just one person who had shed their skin nine times, and whose true body was now unknown.

In short, First Mountain was extremely formidable and daunting, and no one wished to get involved with it unless necessary.

"Emperor Wu, in defending his direct disciple, once exchanged blows with... Number Nine. How did that feel?" someone asked.

Emperor Wu coldly replied: "He is very strong. Although I only deployed a weapon that manifested my form, he also revealed some traces. He is absolutely terrifying and boundless. After all, it's only a human skin; if it had flesh and blood, it would be truly difficult to fathom!"

"Hmm, I also recalled a vague record." At this moment, another person spoke, from the underground world, one of its dark sources.

The underground world had existed for countless ages. It had a bloody side but also explored the truth of the world, unearthing various major secrets from ancient times to the present.

After all, whenever a world developed to a certain stage, it inevitably ended, heading towards annihilation. They wanted to thoroughly research this and break free.

Everyone looked at him, and even Tai Yi showed a surprised expression.

This person had journeyed through the underground world throughout this epoch. In his early years, he had unearthed steles in ruins that did not belong to this epoch and deciphered many texts from them.

"The Coffin that Blocks the Door blocks the realm beyond the heavens, isolating all the myriad realms from it. Otherwise, not to mention the human race, even the immortal race and Immortal Kings would be annihilated. All great realms would wither like bubbles and return to dead silence."

Even as ultimate beings, the few present were greatly shaken. This was terrifying. The sinking of myriad realms and the annihilation of races throughout the heavens was chilling and horrifying to the world.

"According to the records, after that person's great battle, he blocked the gap in the heavens, stopping the spread of the disaster. Furthermore, later generations also saw an unrivaled Heavenly Emperor block the door, suppressing it with a Mother Qi Cauldron. Unfortunately, the stele is damaged, and the records are limited."

This ultimate being from the underground world felt regret. Back then, he had been moved, but later, as his strength grew, he grew to disbelieve the records somewhat, no longer taking them seriously.

But now, seeing the Coffin that Blocks the Door and recalling the old events, sent shivers down his spine. The records on that stele might actually be true, not exaggerated.

His words truly shocked the few present once again: blocking the door more than once?!

"Will we also have to block it one day?" someone whispered.

In an instant, everyone's expressions changed. What were they doing now? Not blocking the door, but dismantling it!

"We still need to evolve further, otherwise..." someone spoke, shaking their head and pausing after every few words.

Everyone knew what he meant: even as ultimate beings, it was still not enough. They needed to continue advancing and transforming again.

Every epoch inexplicably ended. The stronger the being, the more anxious and uneasy they became, and the more they reached this level, the more they felt a bottomless pit in their hearts.

The path ahead was shrouded in dense mist. Everything was too eerie and terrifying.

The master of the Black Blood Institute questioned, saying: "This... isn't right. Although the Great Underworld is a realm that should exist according to deductions, it's not as if absolutely no one has ever been there. Perhaps in the last epoch, or even earlier ancient times, predecessors walked that path. Is it really that dangerous?!"

The Great Underworld was indeed terrifying. To the people of the Yang Realm, it was the underworld, a purgatory. Once the two realms connected, it would surely cause the sky to fall and the earth to crack, bringing untold suffering to living beings, with hundreds of millions dying.

However, the ultimate beings believed that the disparity between the two realms was not that great. A battle was possible; it wasn't necessarily true that the Yang Realm was much weaker than the Great Underworld.

"Regarding the records of the Coffin that Blocks the Door, has its terrifying nature been exaggerated?"

"Is the Great Underworld the realm beyond the heavens? It doesn't seem likely!"

"Clearly, this portal is not the legendary door."

"However, no matter how we look at it, there seems to be some connection, and the methods are similar!"

"What do you think about this matter? Should we alert First Mountain and invite the sequence beings there for a discussion?"

People spoke one after another, because something was indeed amiss here.

If that trace of doubt was not resolved, it would always make them uneasy.

"Don't forget, Li came out of First Mountain. He once trained there!" someone reminded them.

"It wouldn't hurt to invite the beings from First Mountain out for a discussion. Don't forget, there's also a legend that Li was First Mountain's sacrificial offering, sent out as a blood sacrifice," a being glowing with silver light spoke.

His soul power was exceptionally strong, enough to awe the world. Even other ultimate beings were wary of him; rarely could a being's soul power be this strong.

These words were astonishing. If they were to spread outside, they would surely cause an uproar.

Beings of this level knew some of the truth from back then. Li's cause of death was shrouded in mystery, and the few present all had their own conjectures.

Chu Feng, if he were here, would surely break out in a cold sweat. He had heard similar rumors, and even when impersonating a disciple of First Mountain, someone had told him that he was offering himself up for death, a voluntary sacrifice.

Someone told him that First Mountain accepted disciples in every era, and all were peerless geniuses of the world. Yet, in the end, not a single one had survived!

Among them, the most famous was naturally Li!

Of course, some also said that First Mountain's disciples were not sacrificed, but rather entered another battlefield, a more brilliant world with a more bloody and cruel grand battlefield.

Just like the legendary descendants of the Heavenly Emperor, they actively embarked on a path of slaughter.

And Heavenly Venerate Yu Shang, it is said, was a branch of the Heavenly Emperor's descendants. Their ancestors had physical problems and thus remained behind. It was regrettable, lamentable, and tragic that this branch ultimately had only Yu Shang left, falling to such a state.

Mainly, history was too profound and too ancient. Some people had long been forgotten. To this day, the names of emperors could not be heard; everything had been forgotten by the world.

Otherwise, how could the Yu Shang lineage be like this? Who would dare harm them? Even those with greedy ambitions would likely incur public wrath!

After all, everything had become legend. The past could no longer be verified.

What did past achievements leave behind? Only incomplete rumors remained.

Epoch after epoch passed. The beings of former eras turned to dust, and later generations of descendants had already changed countless times over.

First Mountain was very quiet. It had been sealed for some time.

Number Nine stood in the mountain, staring at the master of the Black Blood Institute. He showed a chillingly white smile, making this overlord of the underground world almost want to turn and leave, unwilling to be further involved with him.

Because, no matter how one looked at it, Number Nine's true body most likely had serious issues! One day, if flesh and blood reappeared, who would he be, and what kind of being would he be?

"You want to invite me out? But the mountain is sealed; I can't leave."

Number Nine sighed. There was a pile of ashes at his feet. Then he burned paper again, muttering: "Li, rest well. I'll kill all those people later!"

These words rendered the master of the Black Blood Institute speechless for a moment. Was he trying to intimidate him?

"The Coffin that Blocks the Door has appeared!" The master of the Black Blood Institute informed him of the details.

"Hmm?!"

In an instant, Number Nine was moved. Even as a mere human skin, it swelled up as if it had flesh and blood. His hair flew wildly, and from his hollow eyes, divine light shot out, tearing through heaven and earth!

Ultimately, Number Nine left the mountain. Accompanying him were Numbers Six and Three!

On the way, the master of the Black Blood Institute explained: "Li died long ago. What appeared this time was merely a wisp of his obsession. We did not kill him. Our contact and skirmishes with him were only to clarify what happened back then and to retrieve the supreme scriptures lost in the Great Underworld. Everything is for our Yang Realm."

Number Nine said: "I know he was just a wisp of obsession. If it had been his true body, we old fellows would have gone out and killed you long ago!"

The master of the Black Blood Institute immediately fell silent; no wonder the other ultimate beings refused to come. This was truly impossible for pleasant conversation.

He had a good temper. If it had been any of the others, a fight would likely have already broken out.

On the way, Numbers Nine, Six, and Three actually merged into one body, forming a single figure, calling themselves: Nine-Six-Three.

In Yin State, several ultimate beings stood. Upon seeing the merged form of the three numbers, they all showed surprise, because this being was extraordinarily powerful!

"I've always been curious: are you beings of a sequence, or are you the nine skins shed from one person's nine transformations? And will Number Ten eventually appear?" At this moment, the being with dense silver soul light all over his body spoke. He was one of the dark sources of the underground world.

In fact, his question was also a common thought among the ultimate beings, all of whom had previously investigated it.

"If Number Ten were to appear, would that be considered the ultimate form? There wouldn't be a Number Eleven, would there?" asked the overlord shimmering with silver soul light.

The merged form of Number Nine was expressionless as it said: "Some names cannot be spoken. If you dare to utter them, I believe your life will be short and you won't live much longer. Furthermore, I see that your glabella is dark, indicating you've already met with terrible misfortune. Young man, be careful. Misfortune comes from the mouth. Taboos cannot be spoken. They cannot be mentioned casually."

Then, Nine-Six-Three carefully stared at the overlord covered in silver soul light, saying: "You have some tricks. You crawled out of the Soul River and dare to appear in this world?!"

As soon as these words were spoken, everyone's expressions changed!

The few present knew the identity of this being, who was covered in dense silver soul light. He was the progenitor of the Soul Light Cave, reputed to exist as long as heaven and earth, and one of the dark sources of the underground world!

However, they did not know that the progenitor of the Soul Light Cave, with whom they had cooperated for many years, actually had another origin, coming from the Soul River!

This matter was very serious, truly too astonishing!

Perhaps Tai Yi had suspected it.

In fact, when the merged form of Number Nine mentioned that the master of the Soul Light Cave was about to suffer terrible misfortune, something indeed happened.

A terrifyingly black dark light, without a sound, entered the Soul Light Cave!

At the same time, Chu Feng was packing and harvesting in the Phoenix King's cave mansion, muttering to himself: "The Soul Light Cave isn't very far from here. It's also in Qing State, near the upstream end of the Sun River. Should I go and take a look?"

He learned here that some of the great medicines of the Soul Light Cave were not all cultivated in that mysterious cave, but a portion were planted on small islands in the Sun River, utilizing the power of solar fire essence to nourish the growth of soul medicines, making them ultimate Yang soul medicines.

In the Phoenix King's cave mansion, the Soul Strengthening Grass Chu Feng harvested was already astonishing. But after investigation and interrogation, he learned that there were even more astonishing soul medicines in the Soul Light Cave, one of the rarest great medicines in the Yang Realm!

"I'm not a bandit; I'm just going to take a look this time!" He spoke righteously, even convincing himself of his own words.

He felt that he probably wouldn't have a chance to harvest anything now. However, this trip counted as scouting, and he would definitely go later!

He didn't know that perhaps he genuinely had a chance if he went now. The Soul Light Cave was destined for disaster today!
