Creation furnace, refining space, ice polar realm.

At this moment, in the very center of the Extreme Realm, a blue figure was sitting cross-legged on the ice peak.

Countless cold qi enveloped this figure, almost forming a substance. However, whenever the cold qi tried to invade the body of this figure, there would always be a flash of yellow light, enveloping part of the cold qi and blocking the rest of the cold qi from the figure's body.

At the same time, at the position of the figure's chest, there was a white diamond-shaped crystal emitting white light outward, and the surrounding cold air would be absorbed by the light before it had time to avoid it.

This figure was none other than Lin Feng, who was cultivating the Extreme Method, and the crystal on his chest was the cold chalcedony.

At this time, Lin Feng had already opened up the first level of meridians under the Twelve Righteous Meridians, a total of one hundred and forty-four, which were extended by the main part of the Twelve Righteous Meridians and filled all parts of the human body, which could effectively strengthen the Twelve Righteous Meridians and at the same time enable the internal force to run all over the body.

Previously, Lin Feng's internal force was transported to all parts of his body through exercises every day, and it was necessary to go through two transformation processes, so that the internal force could not be circulated. Therefore, a martial artist who has not yet broken through the I Ching Realm has a limit on the amount of internal force in his body, and it is impossible to engage in a long-term attrition battle.

And the martial artists who have opened up the first level of meridians in the Yijing Realm have completed the initial cycle of internal force, and they can be retracted and released freely, which can be regarded as getting rid of the phenomenon of depletion of internal force. Of course, this is only relative, and if you keep using a move that consumes a lot of energy, you will still run out of internal energy.

Feeling the internal force flowing throughout his body, Lin Feng had never felt so abundant. At this time, the cold air around him was still absorbed and refined by Lin Feng, and at the same time, he began to open up the second-level meridians.

The first level under the 12 canons corresponds to the 12 meridians, the second level under the 12 canons corresponds to the 12 sutras, and the third level under the 12 sutras corresponds to the 12 milli sutras, totaling 20,736 meridians.

The I Ching realm only needs to open up other scriptures, and you can promote the condensation acupoint realm, condense the meridian acupuncture points, and open the secret realm of the human body.

However, this is only the choice of most ordinary martial artists, but those with outstanding talents want to open up the meridians of the second level, so that the internal force in the body is like a dragon and galloping like thunder.

However, those who can really successfully advance to the second level will not survive, and many martial artists will not be able to suppress the increasingly active internal force, and they will have to choose to break through the realm, thus losing the opportunity to advance.

Even if it is the first level, among the thousand martial artists, there may not be a single successful promotion, Lin Feng can succeed, and it is all due to the ban method to seal the operation of Zhou Tian in the body, resulting in the suppression of internal force activity, otherwise, with his yellow-level qualification, he would have been unable to suppress the internal force activity for a long time, and chose to break through the realm.

As for the third level, it is a legendary realm where even one of the hundreds of millions of people may not be able to ascend, and it is called the holy realm. Those who can reach this state have already broken through the limits of human beings and become extraordinary.

Soon, Lin Feng opened up the first end meridian, and with the opening of the end meridian, Lin Feng felt a suction force coming out of his body, and a stagnant area appeared in the surrounding cold air. The cold qi was quickly refined into internal force, pouring into the last meridian, Lin Feng felt a sense of restraint in his entire body, and he couldn't wait to break the restraint and enter a new realm.

"Could it be that I have reached the limit, I now feel that my body is desperately eager to be promoted, and even affects the will body, and at the same time, the acupuncture points on the meridians are also appearing one after another. Lin Feng's will body clearly sensed the condition of his body.

As a last resort, Lin Feng could only quickly end his cultivation and walk towards the stone slab that was staying on the edge. Soon, the slate carried Lin Feng back to the aerial platform again.
