This is it.

After familiarizing himself with the surrounding environment, and then closing this place tightly, Lin Feng leaned over to the black stone in the center of the small pool, sat down cross-legged, closed his eyes slightly, and slowly adjusted his state of mind.

To be honest, the long-awaited foundation building came immediately, and Lin Feng's emotions had been in a beating state, and it was difficult to calm down.

After a full time of pranayama and a stick of incense, Lin Feng's state of mind finally returned to calm, and then he silently ran the "Creation" technique in his heart, all the meridians opened in an instant, and the massive spiritual energy around him converged towards Lin Feng's body.

The technique of dantian tempering is still running, all the aura has just passed through the meridians, and then it turns into a fire dragon and bites towards Lin Feng's dantian, at this moment Lin Feng's dantian is no longer the dry rotten field at the beginning, and now it is a vast and boundless sea, surrounded by spiritual energy, like a fairyland.

As usual, the brown ball came out first to devour enough fire dragons before resting on Lin Feng's dantian.

The fire dragon broke into Lin Feng's dantian, and it was really like a dragon entering the sea, disappearing without a trace.

One fire dragon, two fire dragons, three fire dragons....

The fire dragons kept appearing, and they kept swarming towards Lin Feng's dantian, but Lin Feng's dantian had too much carrying capacity, and so many fire dragons only grew a little bit when they entered.

At this time, Lin Feng wiped his waist, and a Qiankun bag appeared in his hand, and with a wave, all the contents of the Qiankun bag were dumped out.

A small hill of demon stones instantly appeared beside Lin Feng, covering the entire black stone, reaching out and grabbing it, five demon stones appeared in Lin Feng's hand, instantly turning into aura and sneaking into Lin Feng's body.

These demon stones are the harvest of the Tongbei Grassland, Lin Feng has stayed for so long, and finally took them out at this time.

It turns out that this demon stone is also the product of the accumulation of spiritual energy by demon beasts over time, and it can be said that it is an acquired spiritual stone, but after the aura of this demon stone is filtered by the demon beast, the aura emitted becomes much more ferocious, and the general body does not dare to try to absorb the aura transformed by the demon stone, because this will seriously damage the body.

However, Lin Feng was not afraid, after the hammer body of "Pangu Alchemy" and the passage of "Creation", Lin Feng's meridians were full of toughness, and his defense was also extremely powerful, and the fierce demon stone aura was simply insignificant to Lin Feng.

The demon turned into a wind wolf and ran wildly towards Lin Feng's dantian, and finally became a part of this dantian.

The technique of "Creation" was running rapidly, and the aura composed of wind wolves and fire dragons converged towards Lin Feng desperately, and even sometimes the fire dragon would burst, but there was not the slightest damage to Lin Feng's dantian.

Slowly, the amount of aura in the dantian became more and more, and this sea-like dantian was slowly filled.

After a full five days, the demon stones in front of Lin Feng had been absorbed, including several high-level demon stones, all of which were swallowed down by Lin Feng, and now there were only a large number of fire dragons galloping around Lin Feng, and the speed of the spiritual qi was not as fast as before.

Finally, after another five days, the aura in the dantian sea gradually overflowed outward, which was the situation of convergence saturation, and the preliminary work of foundation building was finally completed.

Then the next step is to wash the essence and cut the marrow.

After stabilizing his state of mind, Lin Feng was a little tired, but he was still running steadily the essence washing and marrow chapter in "Creation", when this heart of washing and marrow was just running in Lin Feng's body, the massive aura in Lin Feng's dantian instantly turned into countless flying snakes and rushed towards various parts of Lin Feng's body.

The impact was extremely ferocious, as if it wanted to shatter Lin Feng's body.

The aura in his body poured out, Lin Feng's entire body was bulging, he was a fat man, his skin all over his body became red, his blood vessels and meridians were bulging, and his bones were also creaking, needless to say, it must be extremely uncomfortable.

Lin Feng wanted to shout, but he knew that practicing one breath was to complete the entire process of washing the essence and marrow in one breath, otherwise there would be hidden dangers left, as long as this breath was not held, it would bring permanent defects, and Lin Feng, who pursued perfection, would never allow such a thing to happen.

The whole process was carried out in an orderly manner, and he was never "discouraged".

Fortunately, this process didn't last too long, all the aura rushed out of the body through Lin Feng's body, and a massive amount of aura burst out instantly, and the magma around Lin Feng also rippled, Lin Feng's brows furrowed slightly, and the temperature here increased a lot.

The aura that erupted returned to Lin Feng's body again, but in the blink of an eye, it hit out again.

After going in and out thirteen times, the aura finally gradually stopped, and finally converged in Lin Feng's dantian again, but at this time, the aura in Lin Feng's body was a little less, and the essence washing and marrow were all done by using the aura, of course, there would be a certain amount of consumption.

Then there is the last step, that is, to absorb the aura again, gather the dantian, and then gather all the aura together to form a force, impacting the "level" between the qi gathering and the foundation, as long as you break through this layer, that is the real foundation building monk.

Lin Feng once again hurriedly ran the technique of "Creation", and the fire dragon gathered again.

Fortunately, the aura consumed before was not much, Lin Feng only took five days to let the aura fill the dantian again, and as soon as the aura filled the dantian, Lin Feng couldn't wait to gather all the aura together and turn it into a spear, this spear is the shape of the cold seven spear.

As soon as the "Cold Seven" spear appeared, it rushed towards the "level".

Boom!

There was a thick collision sound in Lin Feng's heart, listening to this sound Lin Feng frowned darkly, how could the "level" be so tough, when would the conjured spear be able to impact it away?

No matter so much, everything has been done, just the last trembling, Lin Feng is determined to rush away.

Boom!

Boom!

Boom!

Hit again and again, but the "level" did not show the slightest sign of sensationalism, Lin Feng was secretly anxious in his heart, this is what the master's manual said!

When Lin Feng was getting anxious, the slow voice of the old man Wanhua came out: "Lin Feng, don't panic, your Zhuji Dan hasn't been used yet." ”

The voice of the old man Wanhua was like a morning bell and a dusk drum, and Lin Feng's secretly anxious mood gradually stabilized again.

With a touch of his waist, the box containing the Tsukidan appeared in Lin Feng's hand, without hesitation, he took out the Tsukidan and put it directly in his mouth, the Tsukidan melted in his mouth, but he didn't expect that this Tsukidan also contains a large amount of aura, how could this small pill have so much aura, this is Lin Feng's first thought after taking Tsukidan.

The spiritual temperature exuded by Zhuji Dan was incomparably warm, and as soon as it appeared, all the dark wounds left by Lin Feng's body that had just been washed and cut off were treated, and after wandering around, they slowly merged into the "Cold Seven" spear, making the body of the spear more condensed.

The role of this Tsukidan is to wish the breakthrough at the last moment.

Feeling the spear after condensation, Lin Feng was full of confidence, and once again controlled "Leng Qi" to rush towards the "level".

Boom!

The fierce attack makes a crisp crashing sound above the "level".

Lin Feng could feel that this level had been broken a little, pursed his lips, and thought in his heart that it had finally had an effect, although the effect was not obvious, but Lin Feng, who was full of resilience, was extremely happy, and it was the most desperate thing to not shake.

Just as he was about to attack the "level" again, Lin Feng's body was shocked, and the whole person was on the spot, and the few traces that had been broken on the "level" just now were actually restored to their original state.

Auto-healing?

The experience manual given by the master does not mention that this "level" still has the ability to repair!

Lin Feng clasped his hands tightly, this time he was really a little anxious, and asked the old man Wanhua, "Grandpa Wanhua, what's going on?" Have you ever been in this situation? ”

The old man Wanhua frowned and shook his head and said, "The old man has practiced for countless years, and this is the first time I have encountered this situation. ”

Yes!

Unexpectedly, the old man Wanhua didn't know, Lin Feng's eyes suddenly opened.

But then the old man Wanhua soothed and said: "Don't worry, from what just happened, it is effective to strengthen the richness of the aura, if you want to break through this "level", then you have to accumulate more aura, as long as the amount of auras reaches enough, it will definitely work." ”

If you don't say that there is an old man in the family, if there is a treasure, the words of the old man Wanhua made Lin Feng's impatient mood recover a lot.

Looking at the surrounding environment, the aura here was not enough at all, and then he looked at the slowly swimming magma, and Lin Feng's eyes flashed with ruthlessness.

At the same time as the ruthless light flashed, the old man Wanhua suddenly felt Lin Feng's mixed sea shaking violently, Lin Feng actually radiated his divine consciousness and threw it into the magma, the divine sense had just entered the magma, and the magma actually began to bubble, and finally turned into aura and penetrated into Lin Feng's body.

It turned out that Lin Feng felt that the aura around him couldn't satisfy his breakthrough at all, so he could only break through the constraints of this space, and Lin Feng clearly remembered that Liu Qingtian told him that this place was the closest place to the spiritual vein, since the surrounding conditions could not satisfy him, then he could only rely on the spiritual vein.

Lin Feng guessed that this spiritual vein was fixed deep underground, so he wanted to find the spiritual vein through his divine sense and get more spiritual energy, because as long as the divine sense touched the place, the spiritual energy could be used by himself.

And when the divine consciousness had just touched the magma, Lin Feng felt a burning sensation enter his head, and the heat rose in an instant, and when he was about to take the divine consciousness back, the feeling of heat dissipated in an instant, and Lin Feng regained his clarity.

At the moment when the feeling of rising heat appeared, Lin Feng wanted to give up this way to absorb the aura, because just that moment of the rising heat had already made him almost lose his spiritual platform and go mad, but after the feeling of rising heat disappeared in an instant, a sufficient amount of aura emerged from the magma, Lin Feng chose to continue to insist, and now as long as he has aura, he can grit his teeth and persevere.

I don't know why the feeling of heat disappears in an instant, but Lin Feng doesn't care so much now, this result is exactly what he wants.

Thinking of this, Lin Feng once again increased the speed of the "Creation" mental method to the extreme, and the surrounding aura was no longer ethereal, but turned into a substance and directly broke into Lin Feng's body, merging into the "Cold Seven" spear.

The aura here was flying like a hurricane, and in the cultivation ground outside of here, the disciples of the Burning Cloud Cave had already made a fuss, but Lin Feng didn't know it.

This situation lasted for three days and still did not subside, the aura never flowed into Lin Feng's body, but the magma did not decrease, but Lin Feng did not have the heart to observe.

Because in the past three days, the feeling of rising heat disappeared immediately as soon as it appeared, followed by another wave that came and disappeared again, each wave could make Lin Feng try the taste of swelling pain, in such a repeated process, Lin Feng's energy was greatly challenged, and the dry and hot environment made him have no sweat to continue to flow out, and even his lips have begun to dry.
