Longevity starts with learning

Moving forward in the sea of ​​blood and corpses, one demon corpse after another passed by Chu Mu's eyes. It was not difficult to distinguish their cultivation in their lifetime.

Demons are similar to monsters, most of them focus on the cultivation of the physical body.

From the size of the body, the internal organs and bones of the body, one can clearly see what the cultivation is.

In this sea of ​​blood and corpses, there are almost no first-level demon bodies. Most of them are second-level and third-level beings, and there are quite a few fourth-level true demons.

Just from these demon corpses, it seems that we can get a glimpse of the cruelty and horror of the ancient invasion of the demon world.

The existence of the second and third levels is almost considered to be the upper-middle level in the current world of immortal cultivation, but in this ancient war, it seems to be just... cannon fodder...

Boom!

As Chu Mu's thoughts flowed, there was a sudden roar. The real demon raised his hand and waved it. A wave of demonic energy flashed, and it seemed that some living creatures exploded and disappeared in the sea of ​​blood and corpses.

Chu Mu looked closely, but he only saw bloody and fleshy pieces falling like rain amid the surging demonic energy.

Looking around, the sea of ​​blood and corpses was obviously not peaceful.

The faint roars and roars seemed to be the charming hums in the ears. Occasionally, a shadow appeared in the bloody darkness, as if it had sensed the horror of the Nascent Soul True Demon, and soon disappeared in the sea of ​​blood and corpses.

Obviously, as the True Demon said, the sea of ​​blood and corpses has existed for too long. Under the great power of heaven and earth, no one can figure out what kind of strange existence will be born in it.

Fortunately, under the deterrence of the True Demon, there was not much danger along the way. Even if there were some storms, they did not cause any waves under the great power of the True Demon.

But this journey also opened Chu Mu's eyes.

The great power of heaven and earth is really mysterious and unusual.

In this sea of ​​blood and corpses, there are flesh and blood monsters that evolved by devouring the flesh and blood of demons. These flesh and blood monsters have no fixed form and are all strange and bizarre, but without exception, their flesh and blood bodies are extremely powerful.

There are also pure souls... ghosts!

It seems that they evolved from the residual souls of fallen demons. The ghosts also have different forms, and their magical powers are also extremely strange, almost impossible to defend against.

There are also pure bone creatures. Chu Mu even saw a skeleton dragon, which was ranked third, but was directly slapped apart by the Nascent Soul True Demon...

"Souls, flesh and blood, bones..."

Chu Mu was thoughtful. Although the creatures born in the sea of ​​blood and corpses were strange, they obviously followed the basic laws of evolution.

Ghosts of the soul, flesh and blood monsters, and demon bone creatures of the skeleton, most of them have traces to follow, and you can see where the source is.

A few creatures that seemed strange and whose origins were unknown were only limited by his own cognition. Their sources were obviously in this sea of ​​corpses and blood.

Although it was an eye-opener, it did not seem to be good news for Chu Mu.

Under the protection of the Nascent Soul True Demon, he could travel freely in this sea of ​​corpses and blood.

But if he came to this sea of ​​corpses and blood alone, based on what he saw and heard, it would probably be a dead end!

When Chu Mu was in a state of heavy thoughts, several days passed in a blink of an eye.

Even at the speed of the Nascent Soul Realm, after several days, this sea of ​​corpses and blood still did not end.

Until the seventh day, Chu Mu was not sure whether it was the seventh day. The Demon Realm was dark, and under the shroud of demonic energy, the sun and the moon were not visible, and it was difficult to distinguish between day and night. In addition, he was in a daze and bound by the True Demon. It was really difficult to determine the time.

The sky was still dark, but a faint blackness appeared between the horizons, which seemed to mean that... the end of this sea of ​​blood and corpses was coming.

As the distance got closer, the blackness became clearer and more conspicuous. Finally, what came into everyone's sight was a huge city!

The city was majestic and the walls were broken. Wherever you looked, you could see several huge cracks in the walls. Through the cracks in the walls, you could also see the rough houses built with huge stones in the city.

Just like the sea of ​​blood and corpses, the traces of time were not very obvious on this majestic city.

On the contrary, the traces of the ancient war were still very clear.

The thick blood stains on the walls, the marks left by the knife and axe, the magic and magical powers, and even the broken array inscriptions were all well preserved under the nourishment of this rich true demon aura.

Chu Mu silently looked at the remaining array inscriptions on the city wall. His eyes moved slightly, and he lowered his head slightly to avoid the gaze of the True Demon.

If it is true that this place was once the bridgehead for the Demon Realm to invade the Immortal Realm as the True Demon said, then this city must be heavily guarded and full of large arrays.

Judging from the cultivation level of the True Demons he saw in the sea of ​​blood and corpses just now, the defense of this city is probably only the fourth level...

In this case, even if the array in this city is broken, from what I can see, there must be a part of it that is preserved, still in operation, or has been silent...

Chu Mu glanced at the True Demon who was looking at the city in front of him without leaving a trace, pursed his lips, and lowered his head again to avoid attracting the True Demon's attention.

"The array inscriptions are different, but the principles should be the same..."

Chu Mu thought to himself that the array is to use the array inscriptions to combine the power of heaven and earth and the spiritual energy of various attributes, so as to complete the process of one plus one being far greater than two.

When cultivators of the same realm face a large formation of the same realm, unless they have a strong understanding of the formation or their own combat power far exceeds that of their peers, they will basically be crushed by the large formation.

Back then in Jingmen, the sword-wielding Yuanying was rampant, but facing the Jingmen formation, he could only use an insider to severely injure the formation master of the Righteous Alliance, then use slow grinding skills to wear him down, and finally use intimidation to force the formation master to retreat.

If the formation master of the Righteous Alliance had not been severely injured by the insider, it would obviously not be so easy for the Changsheng Sect to destroy Jingmen!

And this great formation in the Demon Realm...

The core stronghold of the Demon Clan must be heavily guarded. In the ancient times when the second and third levels were cannon fodder, the great formations in the city, even if they were broken, their power was probably something that ordinary people could not resist. It is possible that the fourth level... could also be easily suppressed!

Chu Mu's eyes were dim, and the depth of "spiritual brilliance" was already revealed in his eyes. A broken wall, countless broken formation ban inscriptions, almost like peeling off silk threads, all flashed in his eyes.

Although he didn't spend years and months concentrating on the formation like you did in refining elixirs and weapons, the core of refining weapons is the formation inscription.

In addition, with the leap of thinking wisdom brought by "Spiritual Brilliance Blessing", it would be easy for him to formally enter the formation.

After two years of preparation in the vast sea, although he only hastily came into contact with the formation, under the influence of the formation in the formation of the weapon refining technique, in just two years, the formation realm reflected on the light curtain panel has reached the second level.

This second level, with the harsh evaluation of the light curtain panel, is definitely not comparable to ordinary second-level formation masters!

"Stop here first."

At this time, the true demon stopped and looked at Li Xiu and Xu Ning. Just a glance, the two bowed and accepted the order, and jumped one after another, and actually left the protection of the true demon and entered the sea of ​​corpses and blood again.

Chu Mu was speechless. His vigilance back then was really right.

These two "old friends" must have reached some kind of deal or consensus with this True Demon, or they have been completely controlled by this True Demon.

Whether what was said back then is true or false, I am afraid it remains to be determined.

"There are two things I need your help with when I enter the Demon Realm."

In the silence, the True Demon looked at Chu Mu and spoke again.

"Please give me your instructions, senior."

Chu Mu looked resigned to his fate.

"First, help this grandson of mine merge the True Demon bloodline and complete the bloodline transformation."

"Second..."

At this point, the True Demon suddenly paused and waved his hand: "You will know after entering the city."

Chu Mu responded silently, without asking, but just glanced at the foolish boy, and he knew it in his heart.

This foolish boy was obviously seriously injured in the soul, and this injury did not seem to be the damage to the soul as he guessed, it should be the injury to... the mind?

Chu Mu was not sure, but there was no doubt that in this situation, blood transformation must be carefully prepared, and there must not be any influence.

This is probably the reason why the true demon asked him to refine the earth spirit fire.

The stronger the true fire, the purer the blood will be, and the more stable the blood fusion and transformation of this boy will be.

However, he remembered that this boy had the mutated red eagle blood, so why did he take the risk of fusing the true demon blood?

"Demon... demon, demon?"

Chu Mu looked at the sea of ​​blood and corpses not far away, and he also felt a sense of weirdness.

As for the demon corpse in front of him, if the dense demonic energy was removed, the demon corpse's form seemed to be no different from the strange monsters in the vast sea.

Both of them used blood as the source of power, and both emphasized physical training.

The difference between demons and monsters is like that between immortal cultivators and monster cultivators. Except for the different attributes of power, there is no difference in other aspects.

"My grandson is going to refine and fuse the blood of a red eagle true demon. This demon blood is of the same origin as the blood of the demon beast red eagle. What you need to do is to refine the blood with true fire, and eliminate the demonic nature without damaging the blood, so as to prevent the demonic nature from eroding Li'er's mind."

Chu Mu asked: "May I ask, senior, is his soul damaged or is he confused? What is the specific situation?"

"Li'er's soul is disordered because I cleansed his soul. In addition to the blood fusion and transformation, I will also set up a soul-nourishing formation to absorb the essence of the demon souls in the mountains of corpses and seas of blood to nourish Li'er's soul. This formation also requires the help of your true fire."

Chu Mu raised his eyebrows, obviously puzzled.

He was not unfamiliar with the method of refining the soul.

When he refines puppets, he often needs to use the soul of a person or a demon after using the soul-condensing stone as a carrier.

These souls cannot be used directly, and they need to be thoroughly cleansed to erase all the memories and emotions in the soul.

Just like formatting, everything in the soul's life is deleted, leaving only a blank soul as the core of the puppet.

Only in this way can he successfully engrave the relevant information of the puppet in the blank soul, thereby completing the refining of the control core of the puppet.

And this young man is the grandson of this true demon. He cleansed his soul for no reason...

If he re-instilled his memory...

Is he going to refine his grandson into a "slave"?

Chu Mu was a little horrified.

"Not what you think!"

The true demon glanced at Chu Mu, obviously guessed what Chu Mu was thinking, and angrily said: "No matter how vicious I am, I will never manipulate my bloodline descendants!"

"If it weren't for the fact that Daheng was unrighteous and manipulated people's hearts at will, why would I have to do this!"

...
