After returning from Luo Yingfeng, Xu Han sent a message to Zhang Zhongqi, and the man immediately entered his cave. Entering the foundation building stage, Xu Han's new cave was located above the Dark Abyss Peak Hall and was close to the Jindan stage monk. His spiritual veins were very good, but he was not here for a long time, so the cave was cheaper like Xu An, a Qi Refining Cultivator.

When Xu Han came back, Xu An was watering the spiritual herbs with spiritual water made from elixirs. All the spiritual herbs in Xu Han's cave were taken care of by Xu An. Although these spiritual herbs would grow at some time, it was quite good to have Xu An take care of them.

"I've seen the young master."

After calling Xu An and giving a few words, Xu Han entered his quiet room.

According to Ma Quanxun, in about four to five months, the Qi Refining Monsters in the Dark Demon Abyss will surge out, and in another seven to eight months, the Foundation Establishment Monsters will appear. Before the Foundation Establishment Monsters appear, Xu Han can make some preparations.

After entering the meditation for a while, Xu Han woke up again. With a wave of his hand, Xu Han took out a gourd.

The gourd is nothing else, it is the gourd obtained by killing Yang Xuan. Later, Xu Han relied on this gourd to absorb the demon insects in the secret ancient medicine garden and escaped the disaster. Xu Han has never found a solution to the demon insects in the gourd. It was only recently that Xu Han found a way. However, the method was a bit dangerous, and Xu Han needed to take some risks.

Looking at the gourd, Xu Han's expression was extremely serious.

With a wave of his hand, the gourd was placed in the center of the quiet room by Xu Han. After that, Xu Han surrounded the gourd and slowly arranged a formation. The formation was very strange, and at first glance it looked like a demon bird devouring insects. Each formation inscription was filled with a strange green light, and it flashed and made the entire quiet room look gloomy and terrifying.

After the arrangement, Xu Han spitted a ball of blood on his mouth and sprinkled it onto the formation.

In an instant, a blood-red light shone out from the green and faint formation. Xu Han's essence and blood were quickly absorbed by the formation. At the same time, Xu Han's face turned pale and his whole body was immediately depressed.

"No wonder the jade slip said that this formation requires the late stage cultivation of the foundation building. If an ordinary foundation building cultivator does not have the late stage cultivation, he cannot withstand the consumption of the spiritual consciousness of the formation." Xu Han murmured to himself.

This is also the reason why Xu Han has not used this formation to solve the devil insects. Arranging this formation requires the spiritual consciousness of the late-stage foundation-building cultivator. With Xu Han’s initial stage of foundation-building cultivation, if it were not for the blessing of the Five Elements Crown, the spiritual consciousness of the Daoxin Demon Art is very powerful, and Xu Han could not withstand the consumption of the spiritual consciousness of the arrangement of the formation. However, from the current point of view, he could barely withstand it.

"I just don't know if so many ancient demon insects can withstand the spiritual consciousness?" Xu Han swallowed a few mouthfuls of pills and murmured.

To solve the ancient demon insects in the gourd, you either kill them or sign a contract. Xu Han estimated that it is impossible to kill the ancient demon insects in the gourd with his current cultivation level. It is impossible to release the ancient demon insects from the gourd slowly, and once they are released, they will release them all. Unless they are absorbed by the gourd, the Yin and Yang Double Halberd will be completely unstoppable.

Another way is to sign a contract, relying on the ancient formations drawn on the ground to sign a contract with all the ancient demon insects at the same time.

This is the only way Xu Han can find in the past ten years.

But the risk is extremely high. The ancient demon insects flocked out, and Xu Han needed to sign a contract with him immediately. At the same time, signing a contract with so many ancient demon insects, Xu Han was not sure whether his spiritual consciousness could withstand it. Fortunately, he obtained this ancient formation through the secret book pavilion of the Dark Abyss Peak, allowing him to sign a contract with the ancient demon insects while reducing the consumption of his spiritual consciousness.

Even so, Xu Han was a little worried.

"After this, I have to try it no matter what." Xu Han secretly motivated himself.

Looking at the gourd in the formation again, Xu Han pointed his finger, and in an instant, a large number of ancient demon insects gushed out of the gourd. So many ancient demon insects were absorbed by the gourd and sealed for more than ten years without any trouble, which could show the terror of these ancient demon insects. He could only harm these ancient demon insects with the Yin and Yang Double Halberd, which shows how strong the vitality of the ancient demon insects is.

In particular, these ancient demon insects can also swallow spiritual consciousness, spiritual power, magic power, and extremely strong. Signing a contract with them will definitely greatly improve Xu Han's strength. Moreover, if you want to deal with these demon insects, you can't deal with them without Yin and Yang magic weapons. Nowadays, he is probably the only one who can use Yin and Yang magic weapons in the cultivation world. With such ancient demon insects as a killer weapon, there is probably only Xu Han himself, and no one else can solve it.

This is exactly why Xu Hangan took risks and was willing to sign a contract with the ancient demon insect.

As soon as the ancient demon worm was released, it buzzed and flew towards Xu Han fiercely.

Unfortunately, the ancient demon worms were trapped by the formation before they flew far away. After that, the ancient demon worms struggled violently, trying to escape from the control of the formation. However, under the constraints of the formation, the ancient demon worms could not escape at all, but fell into the formation on the ground one after another.

Whenever the ancient demon insect falls into the formation, a blood light will immediately be seen drilling into the ancient demon insect's body.

Afterwards, Xu Han's expression changed drastically and he swallowed several pills in succession. But after a while, Xu Han screamed, and finally fell down and kept rolling and crawling in the quiet room. Because each blood light appeared, Xu Han's spiritual consciousness would be consumed once.

How could Xu Han withstand such consumption?

After a long time, Xu Han woke up from the extreme pain.

Xu Han also showed a look of lingering fear, and quickly swallowed several mouthfuls of pills before calming down. But when he saw the ancient demon insect surrendering all over the ground, Xu Han showed a look of relief.

Despite the help of the formation, Xu Han almost couldn't hold on.

In the end, the Daoxin Demon Art did not disappoint him, blocking the huge consumption of spiritual consciousness, allowing him to complete the contract.

Xu Han waved his hand and a large number of ancient demon insects were taken into the spirit insect bag at one time. With another wave, the ancient demon insects swarmed out and launched an attack under the command of his spiritual sense.

Buzzing...

The buzzing sound of the ancient demon insect flying immediately sounded in the entire quiet room. Before Xu Han could express a satisfied look, in the blink of an eye, Xu Han's face suddenly changed and he quickly took back the ancient demon insect.

The spiritual consciousness consumed too much, and Xu Han could not resist it at all.

After thinking about it, Xu Han laughed and said to himself: "It is a blessing to be able to get such a powerful ancient demon insect. I also hope to be able to use it proficiently in the early stage of foundation building. It is simply a delusion."

After releasing a few dozen ancient demon insects again, Xu Han can finally launch an attack more skillfully.

Xu Han was very satisfied with this.

Although there are only a few dozen, these dozens can definitely have the effect of surprise attacks.

He picked up the gourd again, Xu Han used it, and found that the gourd was already in use, and he was even more happy.

Putting away the formation, Xu Han left the quiet room, talked to Xu An, and learned some information. Xu Han entered the quiet room again. This time, Xu Han was preparing to open the original part of "The Demon Art of the Taoist Heart" that was not open in the early stage of foundation building.

Entering the early stage of foundation building, Xu Han read the "Daoxin Planting Demon Art".

He can see the part of the exercises, but Xu Han can't see the subsequent part of the spiritual weapon.

According to Xu Han's guess, his magic power should be insufficient to open the natal spiritual weapon part of "Daoxin Demon Art". Xu Han even speculated that he could only open the natal spiritual weapon part of "Daoxin Demon Art" in the middle stage of foundation building.

For Xu Han, that was a bit late.

As he is about to go to the Dark Demon Abyss, Xu Han must improve his strength. In particular, Xu Han feels that he is not far from the peak of the early stage of foundation building. As long as he uses elixirs to quickly reach the peak of the early stage of foundation building, he may have the opportunity to break through the middle stage of foundation building. As long as he enters the middle stage of foundation building, he should be enough to open the part of the natal spiritual weapon of the "Daoxin Demon Art", so that he can refine his natal spiritual weapon and greatly improve his strength.

Originally, the Five Elements True Artifacts and the Five Elements Sword Techniques all have suitable natal spiritual weapons, but Xu Han did not refine them. For him, his natal skills are the Daoxin-Series Demon Art, not the Five Elements True Artifacts or the Five Elements Sword Techniques. A cultivator can only choose the same natal spiritual weapons, so he can only refine the Daoxin-Series Demon Artifacts, but it is impossible to be the natal spiritual weapons suitable for the Five Elements True Artifacts and the Five Elements Sword Techniques.

For the rest of the year, Xu Han tried to break through the bottleneck in the middle stage of foundation building.

Take elixirs and enter into meditation and practice.

Day after day, Xu Han opened his eyes again a year later. But his eyes were full of regrets.

Relying on the power of elixirs, Xu Han's magic power finally reached the peak of the early stage of foundation building. But he could never break through the bottleneck in the middle stage of foundation building. Xu Han thought hard for a long time and was sure that it was a problem with the martial arts. It was not that there was something wrong with the martial arts, but that there were too many and high-end practices. Every time he broke through the bottleneck, he needed to break through the bottleneck. With his current accumulation, he was far from enough to break through the bottleneck in the middle stage of foundation building.

Although his magic power is far superior to that of ordinary mid-stage monks in foundation building, for him, he still lacks accumulation.

After sitting wither for a long time, Xu Han's expression finally returned to calm.

He took out the original version of "The Demonic Art of the Dao Heart", and Xu Han looked at it for a long time. When he was about to put it away, Xu Han flashed his spirit and said to himself: "Since my foundation is deep, my magic power is far beyond that of ordinary mid-stage cultivators in the foundation building stage, I may be able to open the spiritual weapon part of my natal life."

The more Xu Han thought about it, the more reasonable he felt, so he input magic power into the original version of "The Demonic Art of the Heart of the Tao".

At first, the original foundation-building period of "The Demon Art of the Taoist Heart" was still empty, but Xu Han persisted and later swallowed several pills in succession. Finally, Xu Han was happy to find that some fonts appeared on the blank paper. Although it was not complete, it had already satisfied Xu Han.

Xu Han has already seen clearly what kind of spiritual weapon is in the foundation-building stage of the "Daoxin Demon Art". "It turns out that the spiritual weapon of the Daoxin Demon Art is called the Yin-Yang Ring, and it is the Yin-Yang Five Elements Ring. Now the Five Elements True Art no longer needs to refine the natal spiritual weapon. The Yin-Yang Five Elements Ring can also be the natal spiritual weapon of the Five Elements True Art."

Xu Han was extremely satisfied with the Yin-Yang and Five Elements Ring. But when he saw the refining materials of the Yin-Yang and Five Elements Ring, Xu Han's face suddenly turned dark, and he was even more confused when he arrived. It was because the various refining materials required for the Yin-Yang and Five Elements Ring were either extremely expensive or he had never heard of them.

"Earth loess and demonic flame iron are easy to say. Although I haven't seen it for many years in the cultivation world, I have heard of it a little. But I haven't heard of it before, I've never heard of it." Xu Han smiled bitterly and said. The Yin-Yang and Five Elements Ring are definitely an amazing natal spiritual weapon, but the conditions for refining are too harsh.
