Longevity starts with learning

Boom! Boom! Boom!

The dark sky, blood-colored clouds covered the sky all day long.

The rumbling sound of war drums resounded through the sky, and every drum sound made people's hearts surge, and the desire to kill was almost uncontrollable.

In the sky, one warship fortress after another was hovering in the sky, tilting the surging spiritual light towards the ground.

Or they flew flexibly, avoiding the attacks of demons that came from time to time, and at the same time, they shot out brilliant spiritual light, tearing apart the countless demons that came one after another on the ground.

Some were hit by demons and fell directly to the ground, and were torn into pieces and debris by demons in the blink of an eye, or they were directly blown up in the air, bursting out groups of brilliant light.

The city was majestic, and above the city wall, the light curtain hung from the sky, flickering faintly, which also proved that this city defense formation had not been completely revived, and only basic defenses were retained.

On the city wall, one after another psychic equipment of various shapes, under the control of a cultivator, either poured out pure psychic attacks, or transformed into various spells, divine light, pouring down towards the outside of the city.

All the defects of such psychic equipment are almost insignificant under the overwhelming wave of demons.

Whether it is people, psychic equipment, or even warships and fortresses...

All attacks do not require any aiming, and a random attack will surely fall on the overwhelming demon bodies.

The earth is dead and desolate, with broken limbs and arms everywhere, and more, but there are the seemingly endless, overwhelming demons.

Above the city, several Yuanying masters stood in the air, overlooking the endless blood, and outside the city, above the endless wave of demons, there are also several Yuanying demons sitting in the sky. If we talk about the number of people, it is far more than the Yuanying masters guarding the city.

The city is called Tianyuan, and it is one of the nine cities in the hills. There are five Yuanying masters sitting in the city.

Outside the city, there are as many as nine Yuanying demons.

If it were not for the defense of the city and the protection of the formation, Tianyuan City would probably be submerged in the demon wave in a few days.

Even so, after the alienation of heaven and earth, the demons' offensive in just a few years, several acropolises outside Tianyuan City, and dozens of outpost camps were all destroyed by the demon wave.

Tianyuan City, which was originally one of the core hubs of the nine city defense lines and coordinated the Tianyuan defense line, became the first to bear the brunt of the front line and faced the demon wave offensive.

So far, it has been held for nearly ten years.

Such endless waves of offensives have been staged outside Tianyuan City for countless times.

It is unknown when the demons outside the city, like a tide, finally slowly retreated.

Corpses were everywhere, and blood rushed to the sky.

But strangely, such a tragic and continuous killing did not leave too many traces in this world.

The sky was dark, still covered by the sky like many years ago, and the ground was still dead and desolate. The countless corpses that should have piled up due to the tragic killing did not leave any traces in this world.

It was as if an unknown existence had swallowed up all the countless demon monks who fell outside the Tianyuan City.

Under the city wall, a large number of Immortal Skills Department refiners, array masters, and talisman masters who had been ready for a long time...

All of them stepped onto the city wall in an orderly manner, or went outside the city to repair and maintain the array forbidden equipment damaged after the war.

The battleships and fortresses that almost covered the sky in the sky, except for a few that were still patrolling in and out of the city, most of them landed in the airports opened up in the city.

There were also a large number of monks from the Immortal Skills Department who stepped onto the battleships and fortresses in an orderly manner to carry out inspections and maintenance.

The warriors of the major camps and the several war puppet corps stationed in Tianyuan City retreated from the front-line killing ground to the city in an orderly manner.

Up to now, in the Tiannan Xiuxian world, there has long been no distinction between independent cultivators and sect cultivators.

All cultivators in the Tiannan Xiuxian world, whether disciples of the Changsheng Sect, independent cultivators from various places, or remnants of local forces, are all part of the wartime system of the Human Alliance.

Each has its own assignment and each has its own duties. As long as you are still in the Tiannan Xiuxian world, there is no room for resistance. Even the high-ranking Yuanying power cannot escape the compulsory conscription.

Of course, even if you can escape, there is no peace in the current Xiuxian world.

Escape to any place, it is endless blood. Either you will be devoured by demons, or transformed into a controlled demon puppet, or you will be conscripted by local forces and involved in the endless bloody resistance against demons.

The world is so big, and no one can escape from this demon catastrophe!

Under such circumstances, this Tianyuan City has undoubtedly been completely transformed into a military fortress.

In the fortress, everyone is a soldier!

Everything exists only for this endless war.

After the war, Tianyuan City did not see any easing. Years of fighting have already made a very clear fact clear.

This war has no end, and there is no end to it.

If it were not for the strict wartime system and the alienated world outside the city that strictly restricted the body and mind of every cultivator, this Tianyuan City, and even the entire Hill Nine Cities, would probably no longer exist.

The streets are wide, and the main street runs through the whole city. The shops on the street are all closed, and commercial activities have long ceased to exist in Tianyuan City.

Under the war system, regardless of qualifications, only military exploits are considered, and everything has a unified logistics supply.

The war paused for a while. Apart from the cultivators of the Immortal Skills Division who were in charge of logistics, there were few immortal cultivators on the streets. Most of them exchanged their military exploits for resources. They took advantage of this short truce to concentrate on their cultivation, so that they could have more self-protection power in this catastrophe.

Outside Tianyuan City, on the battlefield that had been killing for more than ten years, a man in a green shirt stepped on the wet mud at some point.

The corpses were gone, and the blood strangely disappeared, but this dark world was always filled with a strong smell of blood.

The source of this bloody smell could not be found.

After all, as long as the creatures died in this alienated world, whether they were demons or humans, they would be swallowed by this world, and no trace would be left, and they would disappear without a trace.

In this case, where did the blood come from?

Chu Mu looked up, the sky was dark, and the alienation of the world had already eroded outside Tianyuan City.

From Yanyun to Zhenbei City, and then to Tianyuan City, there have been more than ten years of killing.

He naturally knows the law of the alienation of heaven and earth very well. In his opinion, the alienation of heaven and earth, if we talk about its essence, is actually the struggle of the world.

The evolution of heaven erodes the world, and the world also instinctively resists the erosion of the evolution of heaven.

The struggle at the level of heaven and earth is difficult to peek, but within the world, it is reflected in the struggle of races.

The land occupied by demons will alienate the spiritual veins and incorporate them into the sacrificial belief system, and the heaven and earth will also be involved in the erosion and alienation.

Just like the scene in front of us, the world outside Tianyuan City was still the normal world of the immortal world before the fall of the front Weicheng camp?

But after the fall, in just a few months, it was transformed into an alienated world, dark and bloody. If it was not a demon who stepped into it, it would be suppressed and rejected.

And the places that have not been occupied by demons, such as Tianyuan City and the northern border behind Tianyuan City, are still normal, and they still look like normal world.

He was in charge of Tianyuan and had tried to recover the lost land, but the result was extremely cruel.

For the alienated world to return to normal, it can be said that it is... as difficult as ascending to heaven!

According to his research, after recovering the lost land, in order to restore the world to normal, the local demon sacrificial system must be destroyed first, and then the spiritual veins must be purified to restore the normal spiritual environment.

Next, according to his speculation, it is necessary to continue to defend, prevent demons from invading, alienate the spiritual veins again, and establish a blood sacrifice system. Finally, the world needs to recover instinctively.

No one can intervene in this, or in other words, the power of the immortal world is not enough to intervene in the evolution of the world.

Compared with the rapid and domineering erosion of the world by the evolution of the sky, the instinctive recovery of the immortal world is much slower.

For an eroded world to fully return to normal, it will take at least hundreds or thousands of years.

Compared with the speed of alienation and erosion in just a few months, this recovery time is almost equal to unrecoverable.

After all, the current Tiannan Xiuxian world is not strong enough to defend the city, so how can it recover the lost territory and hold on for a thousand years?

Not to mention, the resources needed to purify the spirit veins are even more massive. Purifying one or two spirit veins may be possible, but if you want to purify the spirit veins on a large scale...

With the current strength of the Tiannan Xiuxian world, it is simply impossible to do it.

The strength cannot support it, and the resources are even less likely to support it...
