Su Chen has been staying in Qingwu City on standby, often taking the Gathering Spirit Pill and concentrating on cultivation. At the same time, let the ordinary Soul Eater Flying Ants mine in the Mithril Mine Cave, and raise a large group of Mithril Soul Eater Flying Ants in the Golden Gourd.

This is three years.

Su Chen originally thought that after the Penglai Immortal Sect, the Ten Thousand Beasts Immortal Sect, the Double Cultivation Immortal Sect and other large and small sects, mobilized a large number of monks above the foundation building period of their sect, and after coming to Qingwu Immortal City, they would soon launch an attack on the Demon Demon Alliance in Tianfeng Gorge.

Surprisingly, however, the war did not take place for a long time.

Such a large-scale transfer of Immortal Sect cultivators, coupled with the fact that there are a large number of scattered cultivators in Qingwu City, cannot be hidden from the outside world at all.

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

Penglai Immortal Sect is one of the five great immortal sects in Shenzhou, with a strong background, and there is no need to use any tricks to deal with the Demon Demon Alliance, just step by step, crushing the past is enough to destroy the Demon Demon Alliance.

However, the Jindan elders were not in a hurry to attack the Demon Demon Alliance, but had been busy building the city's defense equipment, mobilizing a large number of manpower, and strengthening the fortifications of the Qingwu Immortal City itself.

All the immortal cities in the Immortal Cultivation Realm are not simply for living, but also a fortress against foreign invasions. On the walls of the immortal city, large defensive formations are usually arranged, such as heavy crossbows, heavy spirit cannons, and so on.

Su Chen was also surprised to see these city-guarding equipment for the first time.

Originally, Qingwu City was not of much value, and the local immortal cultivator family could not afford to spend a huge amount of spirit stones to strengthen the defense of the immortal city. And the major immortal sects were reluctant to invest huge sums of money to strengthen the defenses of Qingwu City. If the immortal city is captured by demons and brute cultivators, it is a big deal to take it back.

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

The Penglai Immortal Sect even came to a refining master of the Jindan period with a large group of refining masters to Qingwu City to supervise the construction of heavy spirit cannons.

Millions of catties of copper concentrate were collected, and it took three years to build ten heavy spirit cannons to strengthen the defense of Qingwu City.

This heavy spirit cannon, using spirit stones as an energy source, can instantly burst out with a powerful and lethal burning pillar of light, with an accurate range of more than five miles.

The power of a heavy spirit cannon was enough to threaten the life of Brother Jindan from a distance, so that Brother Jindan did not dare to approach easily.

This city is located within a towering cliff rock, with a small entrance to the city gate. The Jindan Refining Sect Master of the Penglai Immortal Sect built ten of these heavy cannons in one go, which were distributed near the entrance of the city gate. After Qingwu City was greatly transformed and upgraded, it could resist the attacks of at least ten Jindan monks and seal the entrance to the city gate.

As for the other armor-piercing heavy crossbows and the like, which can threaten the lives of the foundation building monks, there are as many as forty or fifty of them, almost all over every corner near the gate of Qingwu City, leaving no dead ends.

Su Chen was also puzzled at first, why did the Immortal Sect spend so much money to strengthen the defense of Qingwu Immortal City.

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

However, considering that Beiyi Manxiu may invade in the future, this move is understandable.

In addition, Elder Ge often sent a part of the foundation building monks to the area of Tianfeng Gorge on the border, and set up a temporary camp to monitor the movements of the Demon Slayer Alliance on the opposite side, and at the same time cut off the penetration of the Demon Slayer Alliance into Qingwu City.

...

In a bitter cold place, the conditions are extremely difficult.

It's nothing if it's cold and cold, and the monks can resist this cold wind, the unbearable loneliness and boredom.

Qingwu City is barely prosperous, there are some taverns, shops and other pastimes in the city, and on weekdays, after the monks have finished cultivating, they can still go to the tavern to wander around and buy a little cultivation materials they need.

But after leaving Qingwu City, he came to a makeshift camp thousands of miles away, and carved out a stone chamber on the hill as a place to live. It is also a vast wilderness, a boundless desolate place, without people.

Under the dim sky, there are only dead wood and rocky hills, and there is no interest. If the monks are stationed here all year round, it is very difficult.

The foundation building monks of Qingwu City will be sent to this temporary camp in turn, staying for three months, patrolling and guarding the border.

Su Chen was ordered to be stationed in this temporary camp together with the twenty foundation-building monks of various immortal sects. The Penglai Immortal Sect, the Ten Thousand Beasts Immortal Sect, the Double Cultivation Immortal Sect, and the Qingwu Immortal City's scattered cultivators each sent five foundation building monks.

At nightfall, a raging bonfire rose in the makeshift camp, barely dispelling a bit of the chill.

When a monk went out to make an inspection, he brought back a fat Lingjiao sheep from hunting, and all the monks gathered around the bonfire with shouts and shouts, drank wine and roasted meat, and roasted and ate.

Among the five Penglai Immortal Sect monks, Su Chen's cultivation level at the third layer of the foundation building period was the highest, and the other four were all monks at the first and second layers of the foundation building.

Two of them are a pair of young brothers and sisters, Shen Xin and Shen Wen, disciples of the Penglai Immortal Sect, who have been foundation building monks for four or five years, and their cultivation is still low.

The other is an old man Lu Wei and a middle-aged woman You Lan. The two of them have no family background, and they have been registered disciples from the Qi refining period, and they have been building foundation monks for more than ten years, but they are still stagnant on the second layer of the foundation building realm.

In this border guarding task, Su Chen's cultivation is the highest, and he is the team leader.

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

Occasionally, he glanced at the Tianfeng Gorge and watched the movement.

The makeshift camp was stationed on the edge of the Tianfeng Gorge, and it was pitch black and there was no light on the opposite side.

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

You can't fly.

The sky of the canyon was extremely strong, and the Tsukiji monk could not fly across the canyon with his sword, and he could be killed by the wind knife halfway.

Only the strength of the Jindan monk can open the talisman and barely withstand this strong wind. But the Jindan monks generally don't take this risk, expend mana, and fly across this canyon.

No one knows if there is a strong enemy in the Jindan period waiting on the other side. If the Jindan monk forcibly flies over, he will lose a lot of mana, and he will be easily attacked by the opponent.

I don't know where the monks of the Demon Demon Alliance passed through this Grand Canyon and arrived in the canyon, hidden in a demon cave somewhere.

Perhaps, there should be a trail on a cliff somewhere that leads down the rock face to the canyon. Then take the trail inside the canyon to the opposite cliff.

In the past three years, all the outposts on the periphery of the Demon Demon Alliance have been uprooted one by one by the Jindan monks of the various immortal sects and the foundation building monks.

The strength of the Demon Demon Alliance monks was not good, and after losing a small number of manpower, they were forced to retreat into the Tianfeng Gorge and never show up again.

The Immortal Sect monks were directly on the edge of this Heavenly Wind Gorge, camping and monitoring the movements of the Demon Demon Alliance on the opposite side.

Now only the old lair of the Demon Demon Alliance hidden deep in the Heavenly Wind Gorge remains, and it will not be able to be taken down for a while.

Tianfeng Gorge can become the nest of the evil demon cultivators of the Demon Demon Alliance, operating for thousands of years, without being completely wiped out by the Divine Immortal Cultivation Realm, or easily occupied by the Beiyi barbarians, there is naturally a reason.

The monks were eating barbecue and talking.

"We've been here for almost a year or two. You say, why don't you Jindan elders still make a move and order to attack the Demon Demon Alliance?"

Someone said anxiously.

As far as I know, three hundred years ago, the Penglai Immortal Sect once encircled and suppressed the evil demon monks of Tianfeng Gorge, and it took ten years and two Jindan monks and hundreds of foundation building disciples to die in battle to exterminate the thousands of evil demon monks here.

However, three hundred years later, there was a resurgence of the Demon Alliance. Even if the three of us join forces, it is not easy to take down the Demon Demon Alliance, just this Tianfeng Gorge in front of us, if we want to go over, it will be difficult. ”

"Then how can we get through this Heavenly Wind Gorge?"

"That's something that you Jindan elders need to think about. This battle has been prepared by the top level for three or four years, and once it starts, it will definitely be the end of the Demon Alliance. ”

"In my opinion, the difficulty is not to deal with the Demon Demon Alliance, but even more difficult to beware of the Beiyi Barbarian Cultivator behind the Demon Alliance. Just in case they support the Demon Alliance.

It will only take ten years to destroy this demonic alliance. However, once a war with the Beiyi Barbarian Xiu starts, it may not be possible to end this war for forty or fifty years. ”

The monks drank wine and ate meat, chatting excitedly, looking forward to the upcoming battle.

On weekdays, they could only get a small amount of Yulu from their respective Immortal Sects, which was not enough for cultivation at all. Although there is a spiritual field, it is also very slow to earn.

Only war can bring them rich booty. At the same time, the Immortal Sects will also offer huge rewards. Killing a Foundation Cultivator of the Demon Demon Alliance is worth the spirit stones they have worked hard for ten years.

Most of the time, Su Chen is silent.

From the first time he went to Qingwu City to inspect the mine incident, he has been here for four years. Penglai Immortal Sect continued to deploy troops, but it was consolidating the defense of Qingwu City, and was always ready to attack, and did not launch a general attack on the Demon Demon Alliance.

He had already guessed that this battle would be difficult.

With the huge strength of Penglai Immortal Sect, he is still so cautious and cautious in this battle, which shows that the strength of the opponent should not be underestimated.

I'm afraid it will be the most difficult battle he has fought since he embarked on the path of cultivating immortals.

It is not clear when this battle will begin.

But once the war starts, it must be a tiger to pounce on the rabbit and deliver a thunderous blow to the enemy.

After a few hours, the monks had eaten and drunk, and the bonfire was gradually extinguished. Except for a few people who were left to guard the camp, the rest of the people went back to the cave to rest.

...

Su Chen returned to the hill of the camp and carved out a stone room. In the stone room, he opened a simple formation disk to shield the prying eyes of the outside world.

Instead of thinking about when to go to war with the Demon Slayer Alliance, it is better to think about how to strengthen yourself and save your life.

Su Chen did not have the excitement of a big war about to break out, but had a sense of urgency. Over the past few years, he has been trying his best to enhance his combat effectiveness.

From the wooden gourd, he poured out a demon banner primordial magic weapon. As soon as the divine thought moved, this demon banner emitted a clear blue light and fell in his palm.

This Yuan Shen magic weapon is extremely powerful, after all these years he has been constantly cleaning with qi and blood, mana and divine thoughts, this demon banner has long been completely recognized as the master and used by him.

However, there are only three primordial gods in the demon banner of the foundation building period, and the power is still a little smaller. In the future, I will also collect some demon beast primordial gods in the foundation building period to improve the power of the demon flag.

This Yuan Shen magic weapon, he can only use it when killing opponents, and it can't be discovered by other monks. Otherwise, if the disciples of the Ten Thousand Beasts Immortal Sect know about it, there will be endless troubles.

Su Chen put away the demon banner with satisfaction, and then practiced in retreat in the stone room.

In the past three or four years since he came to Qingwu City, he has already cultivated the peak of the third layer of the foundation building period. But his subsequent cultivation seemed to be getting slower and slower.

Breaking through the middle stage of foundation building is a small bottleneck, and it takes twice as much time as a small layer of repair. There are even some unlucky foundation building monks who have been stuck in this small bottleneck for decades before they can get over.

Although it is not like breaking through the foundation building and knotting the pill, you need the assistance of the foundation building pill and the mysterious spirit fruit to break through. But it is also much more difficult than the ordinary small class ascension.

I'm afraid that he will need at least a few more years to accumulate vitality before he can break through to the middle stage of foundation building.

This made Su Chen quite worried.

Between the Qingwu Immortal City and the Demon Demon Alliance, the storm is coming, and the war has been prepared for several years, and it may start a war at any time. I'm afraid he doesn't have enough time to slowly cultivate to the middle stage of foundation building.

In the current situation, it is natural that the sooner the breakthrough is made, the better. In this way, his strength can also be significantly enhanced, and his self-preservation power will be strengthened a lot.

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

Su Chen thought for a while and entered his Zhihai Spirit Mountain.

Tao Yao is cultivating under a dense peach blossom tree in Lingshan, "cross-kneeled". The peach branch on its head has three clear vitality peaches, which are particularly dazzling.

Every thousand years, in the Lingshan for three years, you can bear a vitality peach. In nine years, it has produced three vitality peaches.

This Yuan Qi Peach can make the cultivation of the late stage of Qi refining increase by one level, but for the foundation building monks, the effect is obviously much weaker, and it is estimated that it will take a lot of pieces to have a little effect.

Su Chen greeted Tao Yao and picked the three Yuan Qi peaches, with three more Yuan Qi peaches in his hand.

"Woo~!"

Tao Yao stretched out the peach branch and touched the top of its bare head, and couldn't help but show a look of frustration.

This vitality peach actually has no effect on it, and it can't eat it by itself. That's just a by-product of its daily cultivation. Wearing it on his head is more of a show off of his qualifications, showing that he has been cultivating for many years. But now that it's been taken away by its owner, it's gone.

Su Chen appeased Tao Yao, and then took the three Yuan Qi Peach one after another. Taking three Yuan Qi peaches together, I think it should be of some use to break through the small bottleneck in the middle stage of foundation building.

These vitality peaches melted into his abdomen as soon as they entered his abdomen, turning into a pure flow of vitality qi, which was absorbed by his belly, rushing through various meridians, entering the sea of consciousness, and being absorbed by his Qinglian Yuan Shen.

Under the instant impact of the huge Yuan Qi flow, the effect is obviously quite amazing.

"Whew~!"

The flower bone of the Qinglian Yuanshen, the fourth petal, was finally forcibly opened, and the light was bright and moving.

"After four years of hard work, I finally stepped into the fourth layer of foundation building! Fortunately, I have a vitality peach, so I can step into the middle stage of foundation building a few years in advance!"

Su Chen couldn't help but be overjoyed.

He clearly felt that after the Qinglian Yuan Shen broke through the mid-stage realm of foundation building, the mana of the meridians in his body skyrocketed by several percent, and his divine thoughts also skyrocketed in an instant.

The strength of the monk's primordial spirit directly enhanced the innate mana and divine thoughts.

Although the power of divine thoughts can also be enhanced by cultivating various immortal cultivation techniques and the like, such as the "Butterfly Transformation Technique", this is an acquired method. It is not as good as after the promotion of the Yuan Shen, the effect of directly improving the innate divine thoughts is obvious.

Su Chen finished his work, a flash of divine light flashed in his eyes, and there was a crisp sound in his muscles and bones, and he stood up refreshedly and stepped out of the stone room.
