Wu Yan found that he was in a green space at the moment.

Surprisingly, the interior of this space is not large, the radius is not more than a thousand feet, and it is a box-shaped rectangular sealed space.

This made Wu Yan inexplicably think of a word - coffin!

Since this place is a desolate tomb, it makes sense that this forbidden space must be in the coffin in the tomb.

In fact, it's inside the coffin. Because, Shi Chengxiang's next words verified this.

"This forbidden space is the internal space of the Desolate Heaven Coffin that the Great Heavenly Venerable personally refined back then. This desolate coffin is not the same as the desolate coffin rumored outside. You should be able to feel the difference, right?"

Wu Yan nodded.

As soon as he entered this desolate coffin, he actually felt it.

Being in this space, you can sense the extremely strong desolate Heavenly Dao prohibition. The aura of desolation in the space is extremely strong, and it is no exaggeration to say that if there is no extremely special aura, this is simply a holy place for cultivating the mana of desolation.

However, because of that extremely special aura pure, Shi Chengxiang and the others in this space did not dare to absorb the desolate aura here to cultivate.

After sensing it for a while, Wu Yan understood the reason.

The aura of desolation here, due to the influence of the unique prohibition of the desolate coffin, is actually filled with an extremely special power.

This power is related to the law of time.

To be precise, the aura of desolation here contains a kind of prohibition that may be called "time poison".

Anyone who absorbs the breath of the desolation will not only not increase any of the desolate mana, but will even inhale this "time poison", which will cause their own longevity, mana, will, and other aspects to decline rapidly in a negative direction.

Originally, if you are in such a space, even if you don't absorb this breath, you will be affected by this "time poison".

However, the magic of this desolate coffin is also here.

The "time poison" inside it seems to only work on the two things that are banned within it.

The place in the middle of the internal space of the Desolate Sky Coffin is also the source of the "Time Poison", there is a stone platform that is nine zhang high and nine zhang wide.

In the middle of the stone platform there is a three-zhang square pond, which is filled with a pool of water.

The "poison of time" is emanating from the pool.

In the middle of the pool, there were two things floating, a three-foot-long golden brush, and a three-foot-long and two-foot-wide dark jade book.

These two things, at first glance, seem ordinary, and there is nothing surprising about them.

But Wu Yan knew very well that they were by no means ordinary things.

If nothing else, the Holy Pen of Silence that Shi Chengxiang just mentioned should be the golden brush. As for that dark jade book, I think it should be the transformation of the Netherworld Heavenly Dao World!

On the jade book, there are three large, four small and seven inscriptions, which are ancient Hongmeng characters, which are "Book of Life and Death" and "Netherworld Dao Classic".

"The Netherworld Heavenly Dao World has turned into this 'Book of Life and Death', what's going on?"

Wu Yan hesitantly looked at Shi Chengxiang and the other four people, with an inquiring intention in his eyes.

The Netherworld Heavenly Dao World is one of the Nine Realms of Hongmeng, if there is an accident, then the Heavenly Dao of the Hongmeng World cannot be considered complete.

"It's been enshrined at this time, and that's what it is. ”

Shi Chengxiang and the others were also a little surprised, obviously they didn't expect that Wu Yan, as the heir of Mending the Heavens, didn't know about it.

"Rumor has it that you have taken the Ancient Bell away from the Ancient Demon Tomb in the Ancient Demon Tomb. Didn't you realize that it was transformed by the Desolate Ancient Heavenly Dao World?" Shi Chengtian looked at Wu Yandao with some strange eyes.

Wu Yan was stunned at first, and then suddenly realized.

Before, he was wondering why the Ancient Bell suddenly disappeared in the Ancient Heavenly Dao World after it was included in the Ancient Heavenly Dao World, and then reappeared.

It turned out that the Ancient Clock had entered the Ancient Heavenly Dao World before, and it was precisely because the Ancient Heavenly Dao World in the later era had returned to its roots and returned to the source of history, so that it could return smoothly.

Wu Yan hadn't thought about this aspect at all before, but now that he thinks about it, he gradually understands.

Of course, if it weren't for the fact that the Ancient Heavenly Dao had completely declined, or even disappeared from the Bitter Sea World, so that Wu Yan had almost no knowledge of the Ancient Heavenly Dao, this would have happened.

Although one of his clones is now in the world of the Ancient Heavenly Dao, he has successfully comprehended the Ancient Heavenly Dao and achieved the position of Immortal Venerable, but if he does not see through Shi Chengtian, he will not be able to see through the mystery.

Speaking of which, it is actually understandable, after all, he only has the mid-stage realm of Immortal Venerable now, and his cognition of the Heavenly Dao is actually still in various theoretical stages, and he has not really understood it thoroughly, so he naturally can't think of this aspect.

"In other words, whoever refines and controls this 'Book of Life and Death' is equivalent to controlling the Netherworld Heavenly Dao World, and can even use this book to control the entire Netherworld?" Wu Yan asked in a deep voice.

"It used to be so, but now it's not quite. This 'Book of Life and Death' was indeed the key sacred weapon to control the Netherworld, but now it has to be added to this 'Holy Pen of Silence', or it can also be called the 'Divine Pen of Annihilation'. This pen is made from the sacrificial sacrifice of the Heavenly Dao of Silence, and has been tempered by the 'Time Venom' in the Desolate Heaven Coffin for endless years, and has the ability to kill all the primordial gods in the Silence. ”

Shi Chengxiang talked eloquently, talking about everything in the Desolate Heaven Tomb, which seemed to be extremely familiar.

"It is no exaggeration to say that in the entire Hongmeng world, the souls of all living beings are under the supervision and control of the Netherworld Heavenly Dao. Even if it's us, it's no exception. No matter who it is, as long as they can refine these two treasures, they only need to find someone's primordial divine breath in the 'Book of Life and Death', and then wipe that person's breath with the 'God Destroying Pen', and that person can be completely wiped out from the Hongmeng world!"

"Huh, so terrifying?"

Wu Yan gasped and looked at the book in shock.

"Is what you said true? as long as the creatures in the Hongmeng world, the divine soul breath are under the supervision and control of this 'Book of Life and Death'?"

"Of course it's true. This thing was born with the innate spirit when Panzu opened the heavens, and it is the source of the soul of all living beings. Of course, non-Hongmeng world creatures are naturally not among them. However, if you can use the 'Book of Life and Death' to ingest its divine soul aura, you can also use this pen to erase it. ”

Shi Chengxiang added.

"You are also the creatures of the Hongmeng world, and the divine soul breath is also in this book, aren't you afraid that others will get these two treasures and then wipe you out?"

Wu Yan saw that Shi Chengxiang didn't have any worry on his face when he talked about this, and he didn't seem to be worried about this at all, so he couldn't help but ask curiously.

"Hehe, I'm naturally afraid. However, although these two treasures are terrifying, if they want to obliterate us, not everyone can do it. First of all, the person who can refine and control these two treasures is talking about it himself, and not everyone has this qualification. At least, we can't even be like this. Furthermore, the mana required to erase the primordial god with the 'God Destroying Pen' will change as the realm is obliterated. If you want to erase our existence, you should at least have a cultivation level that is not lower than our level. Your Majesty thinks that in today's Hongmeng world, how many such existences can there be?" Shi Chengxiang said with a smile.

"I see!"

Wu Yan nodded suddenly. In that case, they really have nothing to worry about.

Looking at the entire Hongmeng world, as far as he knew, only the Dark Dao Venerable, the Merit Holy Spirit and the Netherworld Dao Venerable were higher than the four realms. Except for these three people, I am afraid that there is no existence that can compare with them.

What's more, the four of them are about to leave this realm with the Desolate Sky Tower, once they leave this world, I believe that with the power of the Desolate Sky Tower, they will definitely be able to bring their divine soul breath out of this world completely.

Wu Yan's gaze once again looked at the two holy relics in the stone platform pool.

It's hard to imagine that the Hongmeng Nine Dao has already been refined into nine holy relics by Panzu, rather than simply a Heavenly Dao world.

Collect the nine holy relics and put them all into the Hongmeng world of the Great Wilderness Yuanding, you can restore the Heavenly Dao of the Hongmeng World to its original state, and at that time, with these nine holy relics, you can turn the time and space of the nine Heavenly Dao Worlds that are included in the Great Wilderness Yuanding, so that they can return to the ruined Hongmeng world today.

Once the Hongmeng Heavenly Dao returns, the restoration of the broken Hongmeng world will no longer be a luxury.

Seeing Wu Yan's eyes quietly looking at the two holy relics, Shi Chengxiang and the other four Shi clans, after looking at each other, quietly withdrew from the desolate coffin.

They knew very well that next, Wu Yan would naturally take away these two holy relics. They are here, and it is possible that it is inconvenient for Wu Yan to do it.

Wu Yan didn't expect that these four stone clans were not coarse at all, but very delicate.

In the barren coffin, only himself was left, and Wu Yan took a deep breath and calmed down a little excited.

He did not rush to take out the Great Wilderness Yuan Ding to collect these two treasures, but carefully probed out his holy sense and carefully explored the two treasures.

However, before his Divine Consciousness could touch the two Holy Relics, an incomparably thick poisonous mist of time suddenly rushed up in the pool on the stone platform, eroding towards his Divine Consciousness!

In an instant, Wu Yan felt a terrible burning sensation that passed from the Holy Sense to the Yuan Shen, making him almost scream!

After only two breaths, Wu Yan clearly felt that the holy consciousness he had probed out, the power of the holy consciousness contained in it, had been eroded by the poisonous mist of time!

"What a terrible time venom, the corrosive power is so strong, even my holy consciousness with a trace of immortal will can be wiped out, and I can't resist its erosion even more if I think of other powers!"

Wu Yan couldn't help but feel a pang of horror at the terrifying power of the venom at that time. At the same time, I was even more shocked by the "Book of Life and Death" and the "Divine Extinguishing Pen" floating on the venom of time.

These two holy relics, which have been floating in the time venom for endless years, have not only not been wiped out, but can also absorb the forbidden power in the time venom to improve themselves, which shows the extraordinaryness of these two holy relics.

Of course, Wu Yan also knew very well that he had just used his holy sense to explore these two things, and he had not used his own Desolate Heavenly Dao Laws. If you use it, I believe that your holy consciousness will not be worn out so quickly.

He just wanted to test the power of Time Venom.

Seeing that this venom was so terrifying, Wu Yan naturally wouldn't let these time venoms in the Shitai Pool be taken away by others.

In the next moment, Wu Yan's holy consciousness began to operate according to the divine rune seal, and wisps of desolate heavenly dao aura were displayed in his holy sense.

This time, his divine consciousness did not probe to the pool again, but directly to the stone platform.

To Wu Yan's great surprise, as soon as his holy sense came into contact with the stone platform, the desolate heavenly dao aura emanating from the stone platform merged with the desolate heavenly dao aura contained in his holy sense!

Sensing this situation, Wu Yan immediately stopped hesitating, and between the slight movements of his mind, the Great Wilderness Yuan Ding and the Great Dao Wilderness Realm appeared at the same time.

As soon as the Great Wilderness Yuan Ding appeared, the two holy objects floating on the time venom seemed to be aware of it, and began to tremble, and the time venom that disturbed it also continued to shake.

As the Great Wilderness Yuanding was sacrificed by Wu Yan and floated in the air, the "Book of Life and Death" and the "God Destroying Pen" struggled to get rid of the venom of that time and pounced on the Great Wilderness Yuanding.

At the same time, the aura of time poison that filled the Desolate Heaven Coffin instantly gathered and shrouded towards the Great Wilderness Yuan Ding, as if it had spirituality, and began to explore the Great Wilderness Yuan Ding.

After this treasure was determined, the venom on the stone platform was forbidden, and he decisively gave up the restraint on the two holy relics, allowing them to fly away and pounce on the Great Wilderness Yuanding.

In the next moment, the two holy relics flew directly into the Great Wilderness Yuan Ding, and naturally, they entered the Netherworld Heavenly Dao World and disappeared.

Wu Yan did not go to find out where the two treasures went, but shrouded the Great Dao Desolate Realm towards the stone platform, and at the same time, his holy thoughts were operated according to the rune seal, and he continued to refine the stone platform.

In this process, Wu Yan could clearly feel that his holy consciousness was pouring into the stone platform at an extremely terrifying speed, refining this stone platform.

Sensing that this consumption was still increasing, Wu Yan couldn't help but be secretly frightened. He then turned his palm and took out the top-grade soul source stone he had obtained from Fu Qingwei, ready to absorb and replenish his soul power at any time.

Wu Yan didn't know that he was immersed in this, constantly injecting holy consciousness into this stone platform, and when he was refining this stone platform, the entire Desolate Heaven Tomb was undergoing extremely amazing changes!

At the same time, outside the Desolate Heaven Tomb, Shi Chengxiang and the other four Shi Clan Great Heavenly Venerables all looked at the Desolate Heaven Tomb that was shrinking with surprise and joy. And the fourteen Shi Clan Extreme Heavenly Venerables who comprehended the laws of the Desolate Heavenly Dao under the Desolate Sky Pagoda also seemed to have received some kind of summoning at this time, and they all returned to the outside of the Desolate Heaven Tomb.

Eighteen Shi Clan Heavenly Venerables were then lined up in all directions of the Desolate Heaven Tomb, firmly protecting the entire Desolate Heaven Tomb behind them, and looked around vigilantly.

Anyone who notices the movement here and approaches this side is blocked by them!
