Looking at the few Chengdan grasses in front of him, Liu Yi was ecstatic, he really just dozed off here, and a pillow was sent over there, which was too timely.

Liu Yi carefully counted the number of Cheng Dan grass, there are five, Lu Tie is too generous, Liu Yi doesn't know what to say, five Cheng Dan grass, for most of the monks at the peak of the foundation building period, they can basically break through to the Yu Dan stage.

"Hehe, five Cheng Dan grasses, I think Sect Master Liu should be able to break through to the Dan Stage with 100% certainty, right?" Lu Tie asked.

"Thank you, Lord Luge, with the help of five Cheng Dan grasses, you will definitely be able to break through to the Dan stage. "Liu Yiyi.

"Okay, since that's the case, then Lu will take his leave, hoping that Master Liu will break through to the Yudan period as soon as possible. "Lu Railway.

"Borrow your kind words and take your leave. "Liu Yiyi.

After sending Lu Tie away, Liu Yi immediately called out the retreating doctor Baizhi, handed over the Chengdancao to Yibaizhi and said, "Elder Yi, I don't know if this Chengdancao can be cultivated and planted by itself?"

[None _ False] W: "Cheng Dan Cao, where did the door master get Cheng Dan Cao?" asked Yi Baizhi as he looked at Cheng Dan Cao in front of him.

"Hehe, Lu Tie sent it, how about it? Can it be planted?" Liu Yiyi.

"Planting? It should be possible, I used to study the Cheng Dan grass according to the book records, theoretically it can be cultivated and planted, of course, because there was no Cheng Dan grass at that time, there was no experiment, now, it is just right to experiment, but, according to the theory, even if the Cheng Dan grass can be planted, the growth cycle is also long. "Treat all diseases.

"It's okay, as long as you can cultivate and plant, it doesn't matter how long the growth cycle is. After all. It doesn't matter how long or short. We won't need it for a while. "Liu Yiyi.

"Well, then I'll go and plant. "Treat all diseases.

"Wait, there are five plants in total, I need one plant to improve my cultivation, and the remaining four plants, you use three plants to practice pills, and the remaining one plant is used to plant. "Liu Yiyi.

Three strains are practiced into pills. Not only can it improve the efficacy of the medicine, but there must be more than three pills that can be practiced, therefore, it is the most cost-effective to practice into pills, but if Liu Yi wants to break through the realm, he has no time to wait for Cheng Dancao to practice into pills, so he can only swallow it raw.

This is also a thing that there is no way to do, alchemy. The first is Liu Yihe's best alchemy technique for curing all diseases, but. Even if he wasn't sure that he would be able to successfully refine the pill now, Liu Yi could only hold back the reluctance in his heart and swallow a Chengdan grass raw.

For Liu Yi, he was not worried about not being able to break through to the Dan period, but if he wanted to break through to the Dan period, it would take some time, and now, with Cheng Dan grass, even if there is only one plant, it can only increase the probability of a breakthrough of one percent, for Liu Yi, it is enough, even if Liu Yi cultivates for a period of time, the probability of becoming a Dan is higher, but it may not be able to increase the probability of a breakthrough of one percent, and now, with the increase of the probability of a breakthrough of one percent, Liu Yi naturally chose to break through in retreat without hesitation.

After Liu Yi arranged everything, he immediately began to retreat and cultivate.

Liu Yi was in retreat and didn't know the outside world, because Lu Tie and the others came back and brought back a large amount of elixir and spirit grass, which turned the outside world upside down.

Although, Lu Tie said that the Voidless Cave is extremely dangerous, and the Voidless Cave is indeed extremely dangerous, and many of the monks who entered the Voidless Cave died in the Voidless Cave, and they died at the hands of that kind of strange grass, but the monks who did not die, and the monks who came back were full of harvest and harvested.

"What? In the lightless cave of Aoki City, there is a large amount of spirit grass?" said some of the monks in shock.

"Let's go and see if we can harvest some spirit grass. "Some monks said.

"Don't dream, you don't look at your cultivation, it is said that the Void Cave is very dangerous, and many of the predecessors at the peak of the Dan Stage have died there. "There is humanity. ...

"Is it that dangerous?". There is humanity.

"Yes, it is said that there are Yin Souls there, those Yin Souls are very powerful, unless there are monks in the Dan Period, otherwise, they don't know how to die if they are destroyed by the Yin Spirits, this is not the most terrifying, it is said that there are strange grasses that attack monks, that kind of grass grows like Spirit Grass, but, when you get close, he will attack you, such an attack, the predecessors in the late Dan Period, some of them can't be dodged, do you say that you can dodge a monk in the foundation building period?" There is humanity.

Obviously, although there was a large amount of spiritual grass in the Voidless Cave, those scattered cultivators were still frightened away by his danger and did not dare to go, after all, they were not monks of the Yudan period, and if they went, they were only sent to death.

And the monks of the Dan period, many of them have made breakthroughs in their casual cultivation, and there is no need to take risks in consolidating their cultivation, but the major forces have sent monks to the Void Cave to look for spiritual grass, of course, they are all sent out by some monks in the Dan period, and only the monks in the Dan period are slightly safer, but they are not very safe.

Of course, these big forces also have their own plans for sending people, after all, as a big force, as long as they can obtain a large amount of spiritual grass in the Voidless Cave, even if they lose some Yudan stage cultivators, they can accept it.

However, due to the instability of Xicheng, many forces did not send people to go, after all, Xicheng is not very stable, and after sending people, the power of protection is somewhat insufficient, so it is easy to give others a chance to take advantage of it, but those very powerful forces have sent a lot of monks to go, anyway, for these big forces of them, even if those monks are all lost in the Void Cave, they can accept it.

Of course, all of this has nothing to do with Liu Yi, Liu Yi and the disciples of the first sect are all in retreat and cultivation, in order to break through the realm as soon as possible.

During the retreat, Liu Yi looked at the Cheng Dan grass in front of him, a little unbearable, but in the end, Liu Yi swallowed it raw, although it wasted some medicinal effects, but if there was no Cheng Dan grass, Liu Yi was not sure to break through, so he had to spit out this Cheng Dan grass.

The monk broke through from the foundation building period to the Dan period, the most important thing is to form a golden pill in the dantian qi sea, and during the foundation building period, the aura in the dantian is already liquid, especially in the later stage of the foundation building period, the aura in the dantian qi sea is simply a bay of seawater, and during the Dan period, even if the sea water in this bay is formed into a solid golden pill.

When Liu Yi took this Cheng Dan Grass, the medicinal power of the Cheng Dan Grass caused a monstrous wave in Liu Yi's Qi Sea, and at the same time, it continuously compressed the liquid aura in Liu Yi's Dantian Qi Sea, making it transform into a solid.

Liu Yi was even more overjoyed when he saw that the medicinal power of Cheng Dan Grass could compress the liquid spiritual energy in his dantian qi sea into a solid, so Liu Yi also ran the exercises, cooperating with the medicinal power of Cheng Dan Grass to make his liquid spiritual power solid.

With the passage of time, Liu Yi suddenly found that in the center of the liquid aura of his dantian qi sea, a small piece of solid aura appeared, this discovery made Liu Yi happy, according to Liu Yi's understanding in the book, when the monk knotted the Dan, it was to compress the liquid spiritual power in the sea of qi first, so that it slowly solidified, and finally became solid, of course, due to the compression in the monk's dantian qi sea, therefore, it is impossible to compress all the liquid states into a solid state, the monk generally just runs the exercises, slowly compressed, with the compression of the liquid state, a circular solid will be formed in the center of the liquid aura, when the solid state is stable, it has broken through to the Dan period, of courseIf the exercise is better and the compression force is greater, then the round solid formed inside will also be larger.

Since the longer the compression time, the larger the solid formed inside, which also indicates that the more aura is contained in it, then the power of the golden pill will naturally be greater. ...

Generally speaking, after the solid inside the monk is stabilized, it will continue to compress until the solid inside no longer increases, and then it will no longer be compressed, that is to say, for the set of exercises that he has learned, he can only compress it like this, and the monk will stop, not that the solid inside will stop compressing as soon as it is stable.

Seeing that the round solids in his dantian were getting bigger and bigger, Liu Yi worked harder to run the exercises, making his exercises run at a high speed, making the pressure on the liquid aura in the dantian inside getting bigger and bigger, and also making the round solids inside bigger and bigger.

In the end, a fist-sized solid appeared in Liu Yi's dantian qi sea, and Liu Yi knew that it was the golden pill of the monk in the Dan period, and at this time, no matter how Liu Yi compressed it, the solid inside would not become larger anymore, and Liu Yi stopped running the exercises, but took the opportunity to cultivate invincible**, because every time the monk broke through the realm, there would be aura washing**, and Liu Yi just took advantage of this breakthrough opportunity to cultivate invincible**, which can play a role in getting twice the result with half the effort.

Invincible**, a supreme **cultivation method, the conditions for cultivation are also harsh, and now Liu Yi is taking advantage of the opportunity to break through and cultivate, at other times, there are few suitable opportunities to cultivate, but fortunately, Liu Yi found that even if he takes advantage of the breakthrough opportunity to cultivate invincible**, it can also have amazing effects, which is also the reason why Liu Yi's **strength has always been amazing.

Of course, if you want to take advantage of the opportunity to break through and cultivate **, many monks can't think of it, and even if you think of it, if you want to really cultivate, few can succeed, after all, generally speaking, monks focus on breaking through the realm, and they don't have the energy to cultivate **.

"Roar!" Liu Yi yelled.

At this time, Liu Yi broke through to the Dan period, and ** also made a breakthrough, which can be described as double happiness, so naturally he couldn't help but roar.

After breaking through the realm, Liu Yi naturally went out of the customs, but as soon as Liu Yi came out of the customs, he saw a figure rushing in his direction.

"Door master, it's not good, Tianweimen has made a move!" (to be continued......).
