Su Chen has been on standby in Qingwu City, often taking the spirit-gathering pill, and devoted himself to cultivation. At the same time, he let ordinary spirit-eating flying ants dig in the Misilan Mining Cave and raise a large group of Misilan Spirit-eating flying ants in the golden gourd.

This flash of time took three years.

Su Chen originally thought that Penglai Immortal Sect, Ten Thousand Beast Immortal Sect, Double Cultivation Immortal Sect and other large and small sects would mobilize a large number of cultivators above the foundation-building stage and above from this sect to come to Qingwu Immortal City, and soon launch an attack on the Demon Alliance in Tianfeng Gorge.

But surprisingly, this war has not happened for a long time.

Such a large-scale mobilization of immortal sect cultivators, coupled with the large number of casual cultivators in Qingwu City, can't hide it from the outside.

Of course, Penglai Immortal Sect did not intend to conceal it.

Penglai Immortal Sect is one of the five major immortal sects in China. It has a strong foundation and does not need to use any strange strategies to deal with the Demon Evil Alliance. It only needs to be done step by step and crush it to destroy the Demon Evil Alliance.

However, the elders of the Jindan were not in a hurry to attack the Demon Evil Alliance, but were busy building cities and defending the city, mobilizing a large number of manpower, and strengthening the defenses of Qingwu Immortal City itself.

All the immortal cities in the immortal world are not simply used for residence, but are also a fortress to defend against invasions from other places. On the walls of the immortal city, large defensive formations, heavy crossbows, heavy spiritual cannons, etc. are usually arranged.

This was the first time Su Chen saw these city-guarding equipment and was very surprised.

Originally, Qingwu City was not worth much, and the local immortal cultivation family could not afford huge amounts of spirit stones to strengthen the defense of the immortal city. The major immortal sects were reluctant to invest huge amounts of money to strengthen the defense of the Qingwu City. If the immortal city was captured by evil demons and barbarian cultivators, at most, it would be snatched back.

However, after the discovery of a rare Misilan mine in Qingwu City, the value of this city has increased significantly and cannot be easily discarded.

The Penglai Immortal Sect even came to a Jindan stage weapon refining master to Qingwu City to supervise the construction of heavy spiritual cannons.

Millions of kilograms of copper concentrate were collected, and ten heavy spiritual cannons were built in three years, which strengthened the defense of Qingwu City.

This heavy spiritual cannon, with spirit stones as energy, can instantly burst out with a strong and fatal powerful light column, with an accurate range of more than five miles.

The power of a heavy spiritual cannon is enough to threaten the life of the Jindan monk from a distance, making the Jindan monk dare not approach it easily.

This Qingwu Immortal City is located in a towering cliff and rock, and the entrance to the city gate is small. The Golden Elixir Refining Master of Penglai Immortal Sect built ten such heavy artillery in one breath, distributed near the entrance to the city gate. After the Qingwu City was greatly transformed and upgraded, it can withstand at least ten Golden Elixir monks and block the entrance to the city gate.

As for other armor-breaking crossbows, they can threaten the lives of foundation-building monks, there are as many as forty or fifty, almost everywhere in every corner near the gate of Qingwu City, leaving no blind spots.

Su Chen was not sure at first why the Immortal Sect had to spend so much to enhance the defense of Qingwu Immortal City.

Such a mobilization of troops was obviously not just to guard against the sneak attack of the Demon Alliance.

However, considering that the Northern Yi barbarian cultivators may invade in the future, this action is understandable.

In addition, Elder Ge often sent some foundation-building monks to station in the Tianfeng Gorge area on the border and built a temporary camp to monitor the movements of the Demon Evil Alliance opposite, and also cut off the infiltration of the Demon Evil Alliance into Qingwu City.

In bitter and cold places, the conditions are extremely difficult.

It’s nothing to freeze when the weather is cold. Foundation-building monks can withstand this cold wind, unbearable loneliness and boredom.

Qingwu City is already a bit prosperous. There are some pubs, shops and other entertainment places in the city. After the monks have finished their practice, they can still go to the pubs to buy some of the needed cultivation supplies.

But after leaving Qingwu City, he came to a temporary camp thousands of miles away, and opened stone rooms in the hills as his residence. There was a vast field of land, an endless desolate land, without any people.

Under the dim sky, there are only dead trees and rocky hills, which are useless. If a monk stays here all year round, it will be very difficult.

The foundation-building monks in Qingwu City will be sent to this temporary camp one after another to stay for three months to patrol and guard the border.

Su Chen received the order and stationed in this temporary camp with twenty foundation-building cultivators from each immortal sect. Penglai Immortal Sect, Ten Thousand Beast Immortal Sect, Double Cultivation Immortal Sect and Qingwu Immortal City each sent five foundation-building cultivators.

At night, a pile of storm bonfires rose in the temporary camp, barely dispelling a little chill.

When a monk was out on patrol, he hunted and brought back a fat spiritual horn sheep. The monks shouted and gathered in front of the bonfire, drank wine, and roasted meat.

Among these five Penglai Immortal Sect monks, Su Chen had the highest level of cultivation at the third level of the Foundation Establishment Stage, and the other four were all cultivators at the first and second level of the Foundation Establishment Stage.

Two of them are a pair of young brothers and sisters, Shen Zheng and Shen Wen, a disciple of the Penglai Immortal Sect. They have become foundation-building cultivators for four or five years, and their cultivation is still low.

In addition, there are old man Lu Wei and middle-aged woman Youlan. Both of them have no family backgrounds. They have been hard-working as registered disciples in the Qi Refining Period and have become foundation-building cultivators for more than ten years, but the second level of the Foundation Building Realm has stagnated.

In this border guard mission, Su Chen has the highest cultivation level and is the leader.

Su Chen silently roasted a piece of spiritual mutton and drank a few sips of warm monkey wine to dispel the chill.

Occasionally, he looked at Tianfeng Gorge and looked at the movement.

The temporary camp is located on the edge of Tianfeng Gorge, and you can see that the opposite side is pitch black and has no light.

This Grand Canyon is thousands of miles long and dozens of miles wide.

Flying cannot be flew.

The sky in the canyon has extremely strong wind power. The foundation-building monk cannot fly through this canyon with his sword, and may be killed by the wind knife halfway.

Only the strength of a Jindan monk can open the protective cover and barely withstand this powerful wind power. But Jindan monks generally do not take this risk, consume their magic power and fly across this canyon.

No one knows whether there are strong enemies in the Golden Pill stage waiting on the opposite side. A Golden Pill cultivator will lose a lot of mana and will easily be attacked by his opponent.

I don’t know where the monks of the Demon Evil Alliance passed through this Grand Canyon and arrived in the canyon, hidden in the Demon Cave somewhere.

Perhaps, there should be a path on a cliff somewhere, where you can go down the rock wall to the canyon. Then, from the trail in the canyon to the cliff opposite.

Over the past three years, all the outposts outside the Demon Evil Alliance have been removed by the Jindan monks from various Immortal Sects, leading the foundation-building monks.

The cultivators of the Demon Evil League were not strong enough and lost a small amount of manpower. They were forced to retreat into Tianfeng Gorge and no longer showed up.

The monks of the Immortal Sect set up camps and camps on the edge of Tianfeng Gorge to monitor the movements of the Demon Alliance opposite.

Now only the Demon Alliance nest hidden deep in Tianfeng Gorge is left, and it will not be taken down for a while.

Tianfeng Gorge can become the old nest of the evil monks of the Demon Evil Alliance. It has been managed for thousands of years without being completely wiped out by the Immortal Cultivation World in China, or it is easily occupied by the Northern Yi barbarians. This is naturally because of the reasons.

The monks were talking while eating barbecue.

"We have been here for almost a year or two. You guys, why haven't the Jindan elders taken action and ordered the attack on the Demon Evil Alliance?"

Some people said anxiously.

"What's the hurry! As far as I know, three hundred years ago, Penglai Immortal Sect once surrounded and suppressed evil cultivators from Tianfeng Gorge. It took ten years to pay the heavy price of two Jindan monks and hundreds of foundation-building disciples to kill thousands of evil cultivators here.

However, three hundred years later, the Demon Evil Alliance rekindled. Even if the three sects join forces, it is not easy to win the Demon Evil Alliance. Just the Tianfeng Gorge in front of you will be very difficult to get over."

"Then how can we pass through this Tianfeng Gorge?"

"That's something that all the Golden Elders need to consider. The senior officials have been preparing for this battle for three or four years. Once they take action, they will definitely take the Demon Evil Alliance."

"In my opinion, the difficulty is not to deal with the Demon Evil Alliance, but even more difficult is to beware of the Northern Yi barbarian cultivators behind the Demon Evil Alliance. In case they support the Demon Evil Alliance.

It only takes ten years to destroy this Demon Alliance. However, once the war begins with the Beiyi barbarian cultivators, it may take forty or fifty years to end this war."

The monks of the foundation-building monks drank and ate meat, and were excitedly talking, looking forward to the upcoming battle.

On weekdays, they can only get a small salary from their respective immortal sects, which is not enough for cultivation. Although they are distributed with spiritual fields, they need income very slowly.

Only war can bring them rich spoils. At the same time, each immortal sect will also offer huge rewards. Killing a foundation-building cultivator in the Demon Evil Alliance is worth the spirit stone they have worked hard for ten years.

Most of the time, Su Chen is taciturn.

He has been here for four years since he first visited Qingwu City to inspect the mine incident. Penglai Immortal Sect has been deploying troops and generals, but it is consolidating Qingwu City's defense and is always ready to go and has not launched a general attack on the Demon Evil Alliance.

He could have guessed that this battle would be very difficult.

With the huge strength of Penglai Immortal Sect, he is so cautious about this battle, which shows that the opponent's strength cannot be underestimated.

I'm afraid it will be the most difficult battle since he embarked on the path of immortal cultivation.

It is not clear when this battle will start.

But once a war begins, it will definitely rush to the rabbit with the power of a tiger and launch a thunderous blow to the enemy.

After several hours, the monks had enough food and drink, and the bonfire gradually went out. Except for leaving a few people to guard the camp, the rest of them went back to the cave to rest.

Su Chen returned to the hill of the camp and opened a stone chamber. In the stone chamber, he opened a simple formation plate to block the divine thoughts from the outside world to spy on.

Instead of thinking about when to start a war with the Demon Alliance, it is better to think about how to enhance your strength and save your life.

Su Chen was not excited about a war coming out, but instead felt a sense of urgency. Over the past few years, he had been trying his best to enhance his combat effectiveness.

He poured out a magic weapon of the demon-torture banner from the wooden gourd. With a divine thought, the demon-torture banner emitted a brilliant green light and fell into his palm.

This soul magic weapon is powerful. After years of cleaning it with qi, blood, magic power and spiritual thoughts, this demon-striking banner has long been completely recognized as the main one and used by him.

However, there are only three foundation-building monsters in the Demon-Strike Banner, and their power is still smaller. In the future, some foundation-building monsters will be collected to increase the power of the Demon-Strike Banner.

He can only use this soul magic weapon when killing his opponent, and it cannot be discovered by other cultivators... Otherwise, the disciples of the Ten Thousand Beasts Immortal Sect will know that there will be endless troubles.

Su Chen put away the demon-striking banner with satisfaction, and then went into seclusion in the stone room.

In the past three or four years since he came to Qingwu City, he has practiced the peak of the third level of the Foundation Establishment Stage. However, his subsequent practice seems to be slower and slower.

Breaking through the middle stage of foundation building is a small bottleneck, which takes twice as much time than a small-level cultivation level. There are even some unlucky foundation building monks who are stuck in this small bottleneck for decades before they can get past it.

Although it is not like breaking through foundation building and forming pills, it requires the assistance of foundation building pills and mysterious spiritual fruits to break through. However, it is much more difficult to improve than ordinary small-class people.

He probably needs at least several years to accumulate vitality before he can break through the middle stage of foundation building.

This made Su Chen quite worried.

Between Qingwu Immortal City and the Demon Evil Alliance, the storm is coming, and the war has been prepared for several years, and it may start at any time. He may not have enough time and slowly practice to the middle stage of foundation building.

In the current situation, the sooner the breakthrough, the better. In this way, his strength can be significantly enhanced and his self-protection power will be much stronger.

"It seems that you can only use Taoyao's vitality to forcibly improve your cultivation!"

Su Chen thought for a long time and entered his sea of ​​consciousness Lingshan.

Taoyao is practicing "cross-legged" under a dense peach tree in Lingshan. The peach branches on its head have three clear vital peaches, which are particularly dazzling.
