Jiang Chen walked out of the cultivation hall and was extremely happy. At the same time, he thought of the thin old man who fooled the thin old man and said that he would build the foundation as soon as he reached the mid-stage of the ninth level of the Qi Refining Stage, he couldn't help but feel secretly funny. He thought that the process of building the foundation this time was also very difficult and almost failed to build the foundation.

Seven months ago, with Jiang Chen's desperate practice and the assistance of taking a large amount of pills that increase his cultivation, the concentration of spiritual energy in this secret room is much greater than that of ordinary retreat secret rooms. Therefore, Jiang Chen was one month earlier than originally planned and practiced to the ninth level of the Qi Refining Stage.

After a period of consolidation, Jiang Chen took one of the eleven foundation-building pills he had obtained, and then began to use his power to transform and prescribe medicine.

The foundation-building pill was exerted very quickly. After only more than three hours, Jiang Chen felt like fire was burning all over his body. Jiang Chen knew that the medicine was spreading. He immediately used his spiritual power to guide the medicine to gather through the meridians throughout his body towards the Dantian.

Slowly, the heat in the dantian became more and more intense, so he couldn't bear it. The pain was like a knife cut. Jiang Chen's face turned red at this time, and beads of sweat the size of soybeans kept falling from his forehead. He covered his dantian and moaned in pain, and fell to the ground.

Jiang Chen was lying on the ground and shrank into a ball, while remembering the foundation-building experience that Zi Xi gave him, saying: "After taking the foundation-building pill, the whole body will become hot, and the scorching spiritual power will be gathered into the dantian. At this time, the whole body will be painful. When this scorching spiritual power spreads from the dantian again, look at the spiritual energy in the dantian. If it is still in gas, it will fail to build the foundation. If it becomes liquid, it will succeed in building the foundation."

Just as Jiang Chen thought of this, the scorching spiritual power in his dantian suddenly burst out.

This explosion turned into countless streams of heat flow. It filled the whole body along the eight extraordinary meridians and even penetrated into the bone marrow and brain. But then, he felt that his brain was filthy and could not even think carefully, and everything in front of him became a little blurred...

This pain lasted for three days and three nights before it gradually faded away. Jiang Chen felt that if he had not been particularly firm in his willpower, he would have been tortured to the point of being crazy.

At this time, Jiang Chen struggled to climb to the front of the bed and then lay down.

He gasped and found that he was sweating profusely. However, the sweat was covered with black impurities and a lot of stench.

Jiang Chen observed his meridians and dantian at this time, and found that the Ren and Du meridians had been opened and had the minimum conditions for foundation building.

But after observing the situation in the Dantian again, I was very frustrated to find that although my spiritual power had been concentrated a lot and had a tendency to liquefy, in general, it was still in gas.

If it is the qualification of the Heavenly Spirit Root Holy Spirit Root, I am afraid that the foundation has been successfully established now. However, the qualification of the My Miscellaneous Spirit Root is still far from that.

Jiang Chen sighed lightly. Without hesitation at this time, he immediately took out the second foundation-building pill and took it.

After taking this foundation-building pill, Jiang Chen felt a severe pain in his stomach. The heat flow in his body hit the meridians everywhere. The burning pain was even worse than the one after taking the foundation-building pill just now. He was so painful that he lay on the ground and rolled on the side.

This time, Jiang Chen's pain lasted for five days before he calmed down, and during these five days, he fell into a coma at least three times.

When he woke up, he found that the spiritual power in his dantian was already very dense. Although most of the spiritual power was still in gaseous state, part of the center was liquid.

Jiang Chen made a quick decision and immediately subdued the third foundation-building pill.

This time, the pain on his body was not only much lighter than when he took the second foundation-building pill, but it was much easier than when he took the first foundation-building pill.

But his whole body felt very hot, and he felt like he was being grilled in a fire. He touched his skin and felt that his head, face, limbs, chest, abdomen, and back were extremely hot. And the heat was still increasing. He felt that his brain was burned to a hazy...

It was the next day that his body calmed down, and the liquefaction degree of the spiritual power in the dantian became even more obvious.

Jiang Chen couldn't help but feel happy. So he struggled to take another foundation-building pill, and suddenly... a heat rushed straight from his dantian to his brain, and he suddenly became unconscious due to the heat.

In this way, when Jiang Chen took the eighth foundation-building pill, he found that most of the spiritual power in the dantian had liquefied, and only a small part of the edge was still green gas.

He trembled his hands and swallowed the ninth foundation-building pill suddenly. This time, he felt that the heat flow seemed to be coming very fiercely, and was suddenly hit by the scorching spiritual power and was so baked that he fainted.

When Jiang Chen woke up again with a hot body, he was surprised to find that all the spiritual power in his dantian had liquefied. In other words, he had successfully impacted in a coma just now and entered the foundation-building stage.

He clearly felt that his spiritual consciousness was stronger than in the past. At the ninth level of the Qi Refining Stage, his spiritual consciousness could only feel movements within a hundred feet. But now it has doubled and he can feel every move within a hundred feet.

Moreover, the spiritual power in the body is more abundant. The total amount of spiritual power that has been liquefied in the dantian is at least three times higher than that during the Qi Refining Period.

He thought to himself that in the past, he would have to consume half of his spiritual power by swinging a third level of the Demon Sword Technique, but now he can easily issue four or five without worrying about exhausting his spiritual power. As for the ghost fire technique, the Netherworld Ghost Claw, the Soul Control Technique, the Corpse Control Technique, etc., he can also easily use it.

Jiang Chen was in surprise and immediately wanted to jump up and scream, celebrating that he had finally taken an important step on the road to immortality. But as soon as he got together, he felt a sharp pain all over his body. Then, his legs softened again and fell to the ground, which scared him!

He quickly found out the foundation-building experience that Zi Xi gave him, and after reading it, he realized that although he had successfully built the foundation, the remaining medicinal power of the nine foundation-building pills on his body was still filled with his whole body. If he did not resolve it quickly, he would be at risk of exploding his body and dying at any time.

"It's easy to use the exercises to refine the medicinal power, it's easy to refine them!" Jiang Chen didn't take it seriously at first, but when he started to use the exercises, he realized that the exercises in the Qi Refining Stage could no longer effectively resolve the medicinal power of the Foundation Building Pill.

"It's over, I still don't know how to do the Foundation Establishment Stage's exercises at all." Jiang Chen secretly complained in his heart. The demon skills he had practiced before were only the Qi Refining Chapter, and the skills he had not changed at all.

So, he had no choice but to come out immediately. Although he was still in front of this thin old man, he was still full of spring breeze, but he was actually holding on and was already anxious.

He immediately took two steps at a time and ran to the Deacon Hall of the Lord of the Heavenly Demon Peak, and then used a thousand spirit stones to exchange for the foundation building chapter of "The Demon Art". Then he hurriedly returned to his cave and began to sit down quietly. Continue to practice, dissolve the remaining medicinal power of the Foundation Building Pill, and consolidate the realm. You must know that if you do not consolidate the good realm after building the foundation, you may fall back to the Qi Refining Stage.

After Jiang Chen took another fasting pill, he began to practice according to the exercises recorded in the foundation building chapter of "The Demonic Art"...

In this way, Jiang Chen took another month to refine the medicinal power of the Foundation Building Pill and completely consolidate his realm. Only then did he finally come out of seclusion this time.

It was not until this moment that he secretly thanked that he had the foresight after learning the lesson of refining the foundation-building pill. He bought ten fasting pills before going into seclusion, and once he felt hungry, he would eat it, otherwise he would not have survived such a long retreat.

Now that I have become a cultivator in the Foundation Establishment Stage, I am also a middle-level cultivator in the Heavenly Demon Sect. It is time to make up my plans for the future.

Jiang Chen felt that the most important thing at the moment should be to sacrifice and refine the Demon Order. He should sacrifice and refine it into a magic weapon for the soul.

According to the jade slip of the ancient monk whom he obtained from Qingyou Valley, if you sacrifice a common magic weapon into a soul magic weapon, you can put it in your body like the natal magic weapon of a Jindan period monk, and no one will find it as long as it is not taken out.

This is very beneficial for keeping the secret of the Demon Order. What Jiang Chen is most worried about now is that he is found to have the Demon Order hidden. At that time, with Tu Junde's strength and power, he can easily kill a young cultivator like himself in the Foundation Establishment Stage.

In addition, more important point is that the effect of its own Demon Order has reached its end. It can only restore first-level elixirs and items. If it is not re-sacrificed, its function will come to an end. Not only does it have no benefits for the foundation-building self, it has become a charcoal element.

According to the method of sacrifice and refining the Yuanshen magic weapon, spiritual objects will often increase their power and efficacy after being sacrificed and refined into Yuanshen magic weapon, and may even have hidden functions.

Jiang Chen knew very well that since this Heavenly Demon Order can become the treasure of the Heavenly Demon Sect's sect, the Heavenly Demon Saint Ancestor has been passed down from generation to generation by the previous sect leaders and as the token of the head, it must have its own uniqueness. It is absolutely impossible to just restore first-level elixirs and ordinary items. He was also very curious and wanted to urgently explore the mystery of the Heavenly Demon Order.

And sacrificing it into a primordial magic weapon and placing it into the body is naturally one of the best ways.

Jiang Chen held the Demon Order in his hand, sighed lightly, and took out a white jade porcelain bottle from the storage bag, which contained the Yuan Jing he obtained from the sixth level of the Trial Tower. It was the key thing for sacrificing the Yuanshen magic weapon.

So he penetrated his spiritual consciousness into the jade slip and checked the method of sacrifice and refining the Yuanshen magic weapon. But this look made him stunned. It turned out that there was only one sentence in the jade slip: the method of sacrifice and refining the Yuanshen magic weapon and the natal magic weapon.

Jiang Chen was completely unaware of how to sacrifice and refine his natal magic weapon. Because that was something that only a Jindan stage monk would consider. How could he, a young cultivator in the Foundation Establishment stage, care about it?

But now that it has reached this point, I have to understand it. So Jiang Chen had no choice but to bite the bullet and meet the Demon Soul Ancestor. Now Zi Xi is not in Tianmo Mountain, so he can only go to inquire with his master.

The Demon Soul Ancestor was very happy to see that Jiang Chen had successfully built the foundation and became a veritable foundation-building cultivator. Because his personal disciples were all foundation-building cultivators. If Jiang Chen could not successfully build the foundation, it would make him feel a little embarrassed.

"Chen'er, your spiritual root qualifications are not very good. Even if you get five foundation-building pills in the big test, you cannot ensure the success of foundation-building. So my teacher has always been a little worried. But seeing that you have finally successfully built the foundation, my teacher finally breathed a sigh of relief." The Demon Soul Ancestor gently twisted the long beard under his jaw, obviously very happy.

After hearing this, Jiang Chen felt ashamed and thought that he had used nine foundation-building pills to succeed. If others knew that he was wasting such a waste, I would probably not know how many people would be heartbroken.

"By the way, it's not two months since the Chinese New Year. The master has sent a few of your senior brothers, and they will return to the sect before the Chinese New Year. At that time, you, the junior brother, should meet your senior brothers and sisters." The Demon Soul Ancestor continued.

Jiang Chen naturally nodded repeatedly and then took the opportunity to ask him how to refine his natal magic weapon?

"Native magic weapon? Chen'er, this is something that only Jindan stage cultivators will consider. You are just building a foundation and thinking about what you are doing?" The Demon Soul Ancestor asked in surprise.

Jiang Chen had no choice but to tell the truth, saying that he had entered the cave of an ancient foundation-building cultivator in Qingyou Valley. He found a method of refining a soul magic weapon in the storage bag on his body, so he wanted to refine a high-level magic weapon into a soul magic weapon for use.

So he took out the jade slip and handed it to the Demon Soul Ancestor to watch.

"Master, this jade slip has not said how to refine the soul magic weapon, but only talks about the same method as the natal magic weapon, so the disciple has to ask the master!" Jiang Chen said carefully.

Unexpectedly, when the Demon Soul Ancestor heard him say that he wanted to sacrifice the soul magic weapon, he laughed.

He gently stroked the long beard under his jaw and said, "Chen'er, the soul magic weapon may have been mysterious in ancient times, but now it is no longer a big secret. Not to mention the Jindan stage monks like Master, even many foundation-building stage monks know..."

"I guess you are also confused by the situation mentioned in this jade slip. You think that the power of the soul magic weapon is much stronger than that of ordinary magic weapons, and it can be used in the body. You can use the soul to warm it up... But do you know what it takes to sacrifice and refine a common magic weapon into a soul magic weapon?" asked the Demon Soul Ancestor.

"Is what the master said a Yuan Jing?" Jiang Chen hurriedly asked after hearing this.

The Demon Soul Ancestor nodded. He naturally didn't know that Jiang Chen had obtained the Yuan Jing, but talked freely: "The sacrifice and refining of the Yuan Jing requires Yuan Jing! As the name suggests, Yuan Jing is the Yuan Jing. Some cultivators above the Foundation Establishment Stage will leave a little Yuan Jing after the death of the Yuan Jing collapses. In the cultivation world hundreds of thousands of years ago, no one knew about the function of this Yuan Jing for a long time, so the previous Yuan Jing was wasted, which is a pity..."
