People who are extremely indifferent and have a heart like iron and stone are entangled in evil qi, which is beneficial and harmless, and can even greatly increase their strength with the help of evil qi, but it is harmful to the wood dust of today, and will even affect future achievements.

And these are not known to Mu Chen.

One day, two days, three days, a month passed quietly.

The negative emotions such as killing intent, iron blood, oppression, and irritability on Mu Chen's body all disappeared, and he became a gentle and elegant scholar with a heart like water, and the original wisp of scarlet in his eyes disappeared.

"Xie Yelao. ”

Mu Chen, who had calmed down, understood Ye Lao's intentions, and bowed down and said with heartfelt gratitude.

These days, Mu Chen's heart is always irritable from time to time, not quiet, immersed in the bloodthirsty state of killing demon beasts, but with the recitation of these books, the irritability slowly disappears, until finally disappears and returns to his original self.

"It's that I'm not thinking it through. ”

"Mu Chen, seeing that your strength should have reached the peak of the ninth layer of Qi refining, the next thing to think about building a foundation should have been to tell you a month ago, but your state of mind at that time was completely unsuitable for foundation building, so it was delayed until now. ”

"Uh-huh. ”

Mu Chen nodded earnestly and pricked up his ears.

"You still have four months to build a foundation, and there should be enough time, so I'll explain to you what it means to build a foundation first:

Cultivating immortals is said to be the foundation builder, the foundation builder, gradually accumulating, the righteousness of gain, the foundation builder, cultivating the root of the yang god, and the place where the mind rests and rests...... Building a foundation is like the foundation of a house, only when the foundation is solid and indestructible, can we go further on the road of cultivating immortals. ”

Mu Chen nodded frequently in agreement.

"There are three methods of building a foundation, which are divided into three levels: the first method: forcibly build a foundation with a foundation building pill, and forcibly gather a layer of foundation building platform, the foundation of this method is the weakest, and the lifetime is limited to building a foundation.

The first method does not require high talent, as long as you have the foundation building pill, you can achieve the foundation building.

The second method: build the foundation by yourself, recite a special foundation building formula to absorb the aura of massive heaven and earth, so that the quantitative change is transformed into a qualitative change, so that the aura gathers in the dantian to form a three-layer foundation platform, so build the foundation, the minimum achievement can reach Jindan, as for the Yuan Baby?

The second method has high requirements for talents, control of aura, and soul, and ordinary monks who cannot condense and build the foundation will fail, but once the foundation building stops, the difficulty of building the foundation will increase by a hundred times next time, so they can only use the foundation building pill to build the foundation.

The monk who built his own foundation is nearly ten times stronger than the monk who forcibly builds the foundation of the foundation pill, and this method is most suitable for you.

According to their own talents, beliefs, can be gathered into different levels of the foundation, the highest can gather seven layers of foundations, three floors of the lowest, seven floors of the highest, now the lord of the Xuanwu Kingdom is the seven-layer foundation of the Yuan Shen overhaul, the strength of the end is terrifying.

The old man was a five-story foundation builder, and he couldn't get closer to the infant for the rest of his life, and your goal was to build a five-story foundation at the very least. ”

Ye Lao had a touch of vicissitudes in his words, and he had a strong confidence in Mu Chen.

"The third method: Heavenly Dao foundation, this method has been lost for a long time, and there is no one Heavenly Dao foundation in the entire Xuanwu Kingdom, but it is said that the Heavenly Dao foundation building is ten times stronger than the monks who build the foundation themselves, and can gather up to nine layers to build the foundation, and the early stage of foundation building can be wrestling with the middle and even late stage of foundation building. ”

Hearing the method of building the foundation of the three paths, Mu Chen was shocked in his heart, there is still something in this painter system, even the long-lost Heavenly Dao foundation building.

The foundation of the Heavenly Dao is a little exciting to think about.

"Mu Chen, I am now passing on the mantra of your own foundation building, hoping that you can successfully enter the foundation building period in the next four months and achieve your own foundation building. ”

"Xie Yelao. ”

Foundation building formula: Heaven and earth Lingyu, full of aura, breathing the wind, self-built foundation......

Mu Chen crossed his knees and silently recited the mantra, and the aura between heaven and earth swarmed into Mu Chen's body and dissolved in the aura lake.

"Go and go, find a quiet room to cultivate, don't get in the way of the old man's eyes here. ”

Mu Chen bowed down and thanked him for choosing to leave.

Mu Chen originally wanted to ask Ye Lao to borrow 30,000 spirit stones, but in the end he held back.

There is a quiet room in the school, specially prepared for students who have broken through the foundation building period, and the concentration of spiritual energy in it is slightly higher than that of the Enlightenment Array.

Although the inner courtyard has a high concentration of aura, it is still far from a special ashram.

Under the guidance and guarantee of Master Liu, Mu Chen entered the meditation room and began to cultivate.

The speed of this exhalation of spiritual energy was nearly ten times faster than the mantra of the Qi refining period, but after an hour of cultivation, Mu Chen frowned, and doubts filled his heart.

With the continuous increase of the aura in the body, the wood dust that was at the peak of the ninth layer of qi refining actually advanced to the tenth layer of qi refining, the dantian expanded again, and the aura lake also expanded, reaching a radius of fifteen meters, and its strength nearly doubled.

The system doesn't react to this.

Over the years, he had read the books in the academy, but it seemed that there was no record of the realm after the ninth layer of qi refining.

There shouldn't be a problem, Mu Chen groaned for two seconds and decided to continue cultivating.

Eleventh Layer of Qi Refining......

The 12th Layer of Qi Refining......

Thirteenth Layer of Qi Refining......

Being in a quiet room with a strong aura, with the method of exhaling the aura tenfold, after a month, Mu Chen's dantian could no longer contain the slightest aura, and he pinched his fist, and Mu Chen felt that he was unprecedentedly powerful.

At this time, Mu Chen's recitation of the mantra gathered a rocket technique, the body of the arrow was nearly five times thicker, and the aura emitted from it was also several times terrifying, it was definitely able to kill the demon beast of the ninth layer of qi refining in an instant, and it was turned into ashes in an instant.

Mu Chen continued to recite the mantra of building the foundation, the amount of aura was not increasing, and the quality was slowly changing, Mu Chen was taken aback and hurriedly stopped, he wanted the foundation of the Heavenly Dao, but he couldn't build the foundation by himself, there were too many gaps.

However, the aura has undergone a qualitative change, but it is not a condensation to build a pedestal, but two skull-sized aura droplets are fused into one, and the size of the aura droplets after fusion has not changed, and the quality has been improved, faintly meaning that it has surpassed the aura of the qi refining period and reached the aura of the foundation building period.

This kind of mutant wood dust feels like a good thing, and the strength can still be improved, so he continued to recite the mantra.

In one day, the aura in the Muchen Dantian was reduced by half, but the quality was even higher, and the aura of the rocket technique was once again terrifying compared to before.

Mu Chen crossed his knees, meditated and continued to recite the mantra to absorb the aura.

A month later, the wood dust dantian was full again, and it could not contain the slightest aura.

Mu Chen continued to recite the mantra, this time the aura changed again, and the two merged again, and the aura that fused out had completely departed from the level of qi refining, reaching the strength of the aura of the foundation.

Mu Chen was overjoyed in his heart and just wanted to continue his cultivation, when a strange movement came from outside the door to wake Mu Chen up from his cultivation.

Pushing open the door, Liu Shi walked in with an anxious face.

"Mu Chen, follow me urgently, let's talk as we walk. ”

"Uh-huh. ”

Mu Chen sat up from the ground and followed Liu Shi out of the quiet room.

"Didn't bother you to build the foundation, did you?"

Liu Shi asked worriedly.

"No, Master Liu, I'm still in the accumulation stage. ”

"That's good, here's the thing: Lingyu Academy has such a demon as you, and these days it is rumored that you are the first day genius in Taixing City, the first day of teaching by Lingyu Academy, and there are even voices from the outside world that say: Lingyu Academy has been thriving over the years, and it will soon replace Morning Star Academy to become the number one ranking.

Originally, the teachers were proud of you and did not obstruct such a voice, but today the late stage monk of the Morning Star Academy: Wang Shi suddenly led the first day of the academy: Lingyun to block the door, asking you to compete with it and compete for the title of the first day of the foundation building period of Taixing City.

I opened my mouth to explain: Mu Chen is swallowing the aura and starting to build his own foundation, it is estimated that it will be difficult to compete, and I asked if I can wait for Mu Chen to build the foundation and then compete, but Wang Shi is aggressive, claiming that you don't dare to come, forget it, but you have to sign a contract: Mu Chen fled without a fight, Lingyun is the first day, and even asked Lingyu Academy to come forward to apologize.

After weighing it again and again, Ye Lao agreed, and finally decided to let you go, whether you succeed or not, give it a try, fortunately, you are still accumulating state, if you really start to build a foundation, then even if I apologize in person and be expelled from the school, I will definitely not let you out. ”

When Liu Shi said this, there were many tones, including self-blame, resentment, and ......

"Obviously, there will be a competition between the three universities in a year, but Master Wang just came to block the door with Lingyun at the moment when you were about to build the foundation, and slapped the face of our Lingyu Academy. ”

Liu Shi added angrily, his expression full of resentment.

"Master Liu, I need these materials, can the Academy help me prepare if I get the victory?"

Mu Chen took this opportunity to give Master Liu the list of materials to upgrade all things, and he always had to give some rewards for fighting for the academy.

"A pound of Jinyun ore, a pound of Muling ore, a pound of Huoqin ore, a pound of water ore, and a pound of earth jade ore?"

Liu Shi muttered softly, and finally smiled bitterly.

"Mu Chen, you ......"

The material of 30,000 spirit stones? Liu Shi didn't dare to agree easily, after all, this was equivalent to half a year's income, and it was also a big expense for the school.

"Master Liu, Master Wang brought students to the door to provoke them, shouldn't they pay a little price if they lose?"

Mu Chen's confidence was tinged with a hint of cunning, and Master Liu's eyes lit up when he heard this.

"Muchen, okay, when you win, I'll hand over these materials to you personally. ”

With Liu Shi's personal assurance, Mu Chen let out a breath and the speed under his feet was faster.

After a while, Master Liu came to the square with Mu Chen, and the student Lingyun led by Master Wang had been waiting here for a long time.

The Spirit Formation was opened for Lingyun alone, allowing it to ensure the best attitude, while Master Wang sat and talked with a group of teachers from the Lingyu Academy.

When Mu Chen arrived, the aura in the square seemed to stagnate, the Spirit Enlightenment Array stopped running, and Wang Shi stood up and looked at Mu Chen.

At the first sight of Mu Chen, Wang Shi felt the peaceful, confident, and unfathomable aura on Mu Chen's body, this son was a fierce opponent for Ling Yun.

When the fog dissipated, Mu Chen put his eyes on Lingyun's body, looking at the same age as himself, about ten years old, his eyes were round, revealing a clear, curious gaze, his skin was white and red, and there was a little baby fat, which was very cute.

The heart of a child, not disturbed by the outside world, immersed in the world of cultivation.
