Longevity starts with learning

But the question is...

In just half a year, why has the erosion of the evolution of the sky made such a terrifying progress?

Chu Mu looked at the Changsheng Sect Master. Although he did not speak, the doubts between his eyebrows were also extremely clear.

"I have been deep into it several times, and some of the situations I observed are basically in it..."

The Changsheng Sect Master handed over a jade slip. Although his voice was calm, his eyebrows could not hide the deep fatigue.

Chu Mu took the jade slip and sensed it with his spiritual sense. The Changsheng Sect Master went deep into this completely different world several times alone, and it was reflected in his spiritual sense.

The jade slip was specially made. When sensing it, it was as if you were in the scene. Coming out of this forbidden boundary, it was as if you stepped through the door of space and really stepped into another world.

The sky was dark, brown and red clouds were silted up, and the sunlight could hardly penetrate it. The cold and chilly chill surrounded the body, eroding the body's protective magic power every moment, and even the crackling sound of explosions could be heard.

The ground was wet and muddy. Even though the brown-red soil had turned into a swamp, the glaring brown-red color was still extremely clear.

The entire world seemed to have completely changed its nature. With this immersive feeling, Chu Mu could even sense that this strange world rejected cultivators, or in other words, creatures other than demons.

The spiritual energy of the world was turbid, and it also stained the strands of brown-red, with a strong evil chaos, which was obviously no longer suitable for cultivators to breathe.

The power of the world was also infected and evolved. In the immersive experience, the Lord of Changsheng tried to mobilize the power of the world. Although it was barely feasible, there was also great resistance.

The entire world seemed to have a strong malice towards the existence of cultivators.

Fortunately, the Lord of Changsheng had a high level of cultivation, and after all, it was not something that low-level demons could detect.

As he went deeper into this world, more strange scenes also emerged.

The strange-looking monsters, like a race from another world, live in this strange world, and even have a tribe system.

Although the geographical topography has not changed much, the grass and green plants on this land are either completely dead or adapted to this world through natural selection, turning into various strange plants, without exception, all of which are full of evil chaos.

The spiritual veins that once exuded no longer exuded the spiritual energy of heaven and earth, but the piercing brown-red evil energy.

Such a spiritual vein land naturally became a paradise for monsters, and a large number of monsters gathered around each spiritual vein.

These monsters are also different from the simple tribe system of the monsters wandering in the wilderness. They obviously maintain a relatively strict order and even have a strict division of labor.

Faintly, it seems that a strong breath can be felt from the spiritual vein land.

The leader of the Changsheng Sect approached tentatively, and the picture recorded in the jade slip was distorted and changed, as if some unknown existence was interfering with the outside peeping.

Going further, it was a core city of the Changsheng Sect in the Cangwu River Basin.

Named Cangwu, it stands on a fourth-level spiritual vein and is almost the center of the Cangwu River Basin.

The former Cangwu City was naturally extremely prosperous, radiating hundreds of thousands of miles of area, and was a hub of important cities.

However, today's Cangwu City, like the spiritual veins that are densely distributed in the fallen land, has long become a paradise for demons.

But this Cangwu City is more special.

In this front-line battlefield, the name of Cangwu has long been known to everyone.

The Changsheng Sect uses Zhenbei City as the center to control this huge defense line, and countless cultivators resist demons.

On the demon side, there are not a few demons with spiritual intelligence, and naturally there are corresponding central commands.

And this Cangwu City is the command center of the demons.

It is rumored that there are dozens of fourth-level demons in Cangwu City, and there are also two terrifying fourth-level perfect demons.

It is difficult to tell whether the rumor is true or false.

But within the Changsheng Sect, after years of fierce fighting, it has already been concluded.

In the front line of these nine cities, the number of fourth-level demons that have appeared one after another has exceeded fifty.

Among them, there are more than five fourth-level perfect demons.

In the Changsheng Sect that suffered a heavy blow that year, there were only a handful of Yuanying masters. Facing such a huge force, it was undoubtedly defeated.

Over the years, under the Changsheng Sect's unconditional cultivation, although many Jindan disciples have been promoted to the fourth-level Yuanying, there are also many who have fallen.

To this day, if we talk about the legitimate Yuanying masters of the Changsheng Sect, even if Chu Mu is counted, there are only nine.

Most of them are only at the early stage of the Nascent Soul.

The biggest source of strength is the survivors from all over the Tiannan Xiuxian world and the support from the major tribes on the grassland.

After all, the survivors who can survive this demonic catastrophe and escape to the northern border are naturally not weak in cultivation.

At the very least, they are also mid-to-high-level cultivators.

Although there are many low-level cultivators who escaped, they are either close to them or have extraordinary means and great luck.

However, even so, there are only thirty Nascent Soul masters on the front line of the Nine Cities, and only sixteen of them belong to the Changsheng Sect.

The rest are either independent cultivators, or the remaining Nascent Souls of various forces that are unwilling to submit to the Changsheng Sect, or the support of the major tribes on the grassland.

And there are only three Nascent Soul masters.

One is the leader of the Changsheng Sect, and the other two are the Great Elder of the Prairie Tianluo Tribe, and the founder of the Southwest Tianzhu Alliance, a great Gu Dao master of Nascent Soul.

Although it is difficult for such a force to counterattack, it is naturally not a big problem to defend the city.

As for internal conflicts, in the current situation, although there are conflicts, they have been suppressed to the lowest point.

Once upon a time, the Changsheng Sect spent a lot of manpower and material resources on the outer sea, and no one knew how many lives were lost. It pinned its hope on the so-called Human Alliance to unify the Tiannan Immortal Realm.

But until the Human Alliance collapsed, the Changsheng Sect failed to achieve its wish.

Who would have thought that in this apocalyptic world, after the catastrophe swept through, the Changsheng Sect on the front lines of the Nine Cities would actually integrate the remaining power of the entire Tiannan Cultivation World, and even the former rival Zhengdao Alliance , and now they are all honestly attached to the Changsheng Sect.

Blessings and misfortunes are all caused by fate.

"Junior brother, have you noticed any clues?"

As soon as Chu Mu put down the jade slip, the leader of the Changsheng Sect asked from the side.

Chu Mu was silent for a while and then asked, "Senior brother, have you ever entered the spiritual place?"

The leader of the Changsheng Sect shook his head: "You can't get in."

"Every place with spiritual veins seems to be the hub of that strange world. The sense of heaven and earth is extremely sharp. If you want to sneak into the place of spiritual veins without telling the senses of heaven and earth, it is difficult for me to do so even with my cultivation level. arrive."

"I have forced my way in once before, but as soon as I broke into the periphery of the spiritual vein, the world suddenly changed drastically. The spiritual vein detonated, directly wiping out all traces."

"I speculate that if you want to avoid the changes in the world and the detonation of spiritual veins, you must first isolate the connection between this strange world and the spiritual veins..."

"But now in the Nine Cities, although there are many Yuanying comrades, there is not a single Formation Master in the Yuanying Realm. The defense lines of the Nine Cities only rely on the sect's many previous foundations..."

"That's why I have to ask for help from you, junior brother..."

"Junior brother, you can set up a fourth-level formation before you enter the Nascent Soul. Now that you have reached the middle stage of the Nascent Soul, the level of the formation will inevitably reach a higher level..."

Chu Mu asked: "Senior brother, do you have records of changes in the world and the detonation of spiritual veins?"

"No."

The Changsheng Sect Master shook his head.

Chu Mu was confused: "Why?"

"This is the jade slip that I originally used for recording. Junior brother, if you take a look at it, you should be able to understand the reason."

The leader of the Changsheng Sect handed over another jade slip. The jade slip was light blue and was obviously made of skymark crystals. The surface of the jade slip was engraved with a large number of forbidden inscriptions to prevent the information recorded on the jade slip from being lost or damaged due to external forces.

Chu Mu frowned slightly, and when he took the jade slip and inspected it, he was slightly alert without any trace of it.

But soon, this vigilance disappeared without a trace as the contents of the jade slips changed.

"How is that possible!"

Chu Mu suddenly raised his head to look at the dark sky, his face uncertain, as if he couldn't believe it, but also seemed to have some understanding.

The Changsheng Sect Master looked at the dark world, and his voice was less calm and more powerless: "He has begun to interfere with the rules of the world..."

Chu Mu slowly put down the jade slip. Although he didn't want to believe it, what was recorded on this jade slip seemed to be ironclad facts.

A specially made jade slip made of Tianhen crystal contains the creation of heaven, and everything in the world cannot be imprinted on it.

Even if it is a great monk of Nascent Soul, it is impossible to interfere with the recording of information by the Skymark Crystal Stone.

Not to mention directly erasing the information recorded by the Skymark Crystal.

It seems incredible.

But in this jade slip of Tianhen crystal, it is also a fact.

Judging from the scene recorded on the jade slip, it was as if an invisible hand had descended upon the periphery of the spiritual veins that the Changsheng Sect Master had forced his way into, forcibly erasing the information recorded on the jade slip.

This power may be difficult for low-level monks to perceive, but for those in the Nascent Soul realm, power comes from heaven and earth, so how can they not even recognize the mighty power of heaven and earth!

This kind of great power of heaven and earth obviously cannot be controlled by the great power of Yuanying. After all, which great power of Yuanying can kill a sword under the nose of a great monk of Yuanying? The information recorded on the Tianhen Jade Slips was forcibly erased?

As long as it is not directed and performed by the leader of the Changsheng Sect, it means that this power comes from "Heaven" in the true sense!

Chu Mu's eyes were dark, and after a moment, he looked at the Changsheng Sect Master.

At this time, the Changsheng Sect Master took one step and crossed this boundary and stepped into a completely different world.

Chu Mu stopped for a moment, then followed closely...
