After seven or eight times in a row, Zheng Lei lay down on the ground angrily, still holding the handle of the dagger in his right hand, and said breathlessly: "What the hell is this? After wasting half a day's energy, there is still no result at all, is my method wrong?"

Realizing this, Zheng Lei began to examine his previous methods, seven or eight times before, he had always recovered his spiritual power, and then used it up in one go, and if he failed, he recovered again, and then continued his previous actions, but the result was that he was busy for a long time, and there was no result at all.

After lying down for a while, Zheng Lei suddenly sat up and muttered, "Can you use spiritual power while absorbing spiritual power?"

With that, he closed his eyes and divided his mind into two parts, one part controlled the body to absorb spiritual power, and the other part controlled the body to use spiritual power.

He found that it is indeed not easy to use this dual purpose, absorbing spiritual power is equivalent to being still, and using spiritual power is equivalent to being in a state of motion, and this use of spiritual power while absorbing spiritual power is actually to find a balance point in movement and stillness, and at the same time let there be these two contradictory behaviors in a body.

After repeated trials and trials, each time it ended in failure, once the spiritual power was used when absorbing the spiritual power, his body would be like a deflated ball, and all the spiritual power in the body would be released, and once the spiritual power was absorbed when using the spiritual power, his body would suddenly become like an iron lump, not going in or out, and even the spiritual power could not move, and this stalemate would last for a while before it was unraveled.

Zheng Lei is never afraid of failure, failure means that his method is wrong, as long as he finds the right method and adds his own efforts, there will definitely be a time for success.

At that moment, Zheng Lei looked through the contents of the storage bag again, and finally found the bookless book handed to him by Tian Chengyang, opened the book and read it, he seemed to have found a way, but whether it could be done or not, he had to try it.

This method is the Great Zhoutian.

Originally, his cultivation reached this point, he needed to go through ten months to raise the fetus, further open up the whole body, and then enter the Great Zhou Tian Cycle Period, the entire third step of the stage is called refining Qi and transforming the gods, which means that after the meridians of his whole body are opened, the qi of the human body and the qi of heaven and earth are further combined, and cooperate with his own Yuan Shen to practice, so that the divine qi is knotted, so that the holy fetus is knotted in the middle and lower two dantians, and then the condensation is condensed, and the great Dan is raised, this Dadan, refers to the Jindan condensed by the Jindan Avenue.

Jin Dan he does not have now, but the spirit and qi are there, according to the method pointed out in the book, that is, to suppress the true fire in the heart with God, so that the true fire inhibits the true water in the kidneys, and the water and fire are intertwined in the dantian, the body and mind will be silent, and the real fire will be obtained, and the real water will condense.

The reason why Zheng Lei's body will condense as soon as he absorbs spiritual power when he uses spiritual power is because the true fire and real water do not form a dynamic balance, so there will be that state of condensation of the whole body.

Fundamentally speaking, the essence of refining qi lies in movement, closing, coming, up, down, breathing without stopping for a moment, you can use your mind at first, and then it will be natural, this is what Daozu said, "if it exists, it is not diligent".

And if you want to achieve continuity, you need the foundation of the Great Zhoutian.

Knowing the method, Zheng Lei sat on the ground, adjusted his state, and then took out the only warning talisman in the storage bag and set a small warning formation around it, he knew that the process of cultivation needed to be particularly cautious, once there was an external force rushing, there was a possibility of going mad or even dying, so he had to take precautions.

Slowly closed his eyes, mobilized the spiritual power in his body and slowly began to run, at first, Zheng Lei didn't dare to hold it up, but carefully followed the method in the book to slowly run his spiritual power, after clearing the key, the spiritual power passed through, and his body would have a comfortable feeling.

In this quiet underground, no one disturbed, the danger he suffered before, at this moment, seems to be completely away from Zheng Lei, just gave him a good cultivation environment, because Zheng Lei's speed of practice is very slow, a big week down, it has been three days later, but Zheng Lei is underground, there is no timekeeping tool in his hand, and he doesn't know how long he has passed.

It's just that when he woke up, he found that his body was more comfortable than ever, and it was not only his body that was comfortable, but also his mood.

After this Great Zhou Tian, he found that he no longer had to care about the operation of spiritual power, and gradually became more and more powerful, without his deliberate command, he operated in his body according to the order of the previous operation, and the spiritual power in the air was also constantly sucked into Zheng Lei's body in the process of running on its own in this Great Zhou Tian.

In the process of running this Great Zhoutian, Zheng Lei found that the bead that Lin Xi gave him to detect the surrounding cultivators didn't know when it was integrated into his heart, if it wasn't for the operation of the Great Zhoutian, he really didn't know.

Zheng Lei stood up, his hands were clenched tightly, extremely powerful, he walked to the dagger again, closed his eyes gently, and artificially accelerated the speed of Da Zhou Tian by more than double, and suddenly he felt the spiritual power around him frantically pouring into his body, and his body was like a leather ball, instantly reaching saturation, and it was unbearable to see.

He was waiting for this time, reaching out and grabbing the handle of the dagger, the spiritual power poured into his hand, wrapped around the dagger, and then pulled up little by little.

This time, Zheng Lei's spiritual power has never been exhausted, and the operation of the Great Zhou Tian has made his spiritual power endless, no matter how hard he tries, the spiritual power in his body can be replenished in time, but his consciousness is not in the body at all.

With a pop, the dagger was pulled out by Zheng Lei, and a dazzling blood-red light made him turn his head to adapt to the sudden light.

After getting used to it, Zheng Lei slowly turned his head, the blood-red light on the dagger gradually retracted into the dagger, the dagger blade seemed to have turned into liquid, flowing slowly, holding the dagger, it looked like holding a blood bar.

"Why is it so weird? It's blood-red? It can't be a demonic thing, right?" Zheng Lei said, putting the dagger in front of his eyes and looking at it carefully.

After looking at it for a while, two words slowly flashed out of the dagger: "Demon Heart"

"Sure enough, it's something from the Demon Dao, let's put it away first. Zheng Lei didn't dare to make a mistake, the origin of this dagger is unknown, he didn't dare to use it easily, or wait until he went out and saw the master and then ask him, although he knew that it was a demonic thing, but Zheng Lei did not choose to throw him away, just as Ouyang Hua, who went to Baiyun Temple for the first time, said to him: Righteous people use evil methods, and evil laws are also good, and there is no difference between good and evil in the weapon itself, just look at the heart of the person who uses the weapon.
