On the fifth floor of the Polar Yin Cave, in a misty pool.

The chapter rat was half naked, immersed in the steaming water, meditating with his eyes closed, and the blood veins around his body were prominent, looking very terrifying.

At this time, in his Divine Mind Sea, Bai Jin was dressed in white, and said with a chic smile: "Senior Brother Zhang, how about this Milk Cloud Spring I brought you here?"

With a flash of brilliance, the incarnation of Zhang Mouse's divine thoughts emerged, hugged his hands, and saluted in surprise: "Senior Brother Bai, this place is really magical! I only soaked for half a day, and my true qi has skyrocketed by three percent, and at this rate, in two days, I will be able to try to hit the bottleneck of foundation building." However, the junior brother still didn't understand, since this place was so magical, why didn't the master open it to us ordinary disciples?"

"Hehe, how can an ordinary disciple have a chance to use it! This is a patent for a disciple who has passed it on to himself! Moreover, he must have made a meritorious contribution and received a commendation from the master before he can enter! Do you think that this Milk Cloud Spring is some kind of ordinary spring water as cheap as Chinese cabbage? This is a pool of spring water that gathers the essence of heaven and earth, and it took many years to conceive it! If you also come to soak it, I will also soak it, won't I soak all the essence in this spring water?"

As he spoke, a stalactite hanging low above the pool water just condensed a drop of milky white liquid, and it fell into the pool water with a dingdong, and suddenly a rich and pure heaven and earth vitality spread in the pool water, making Zhang Mouse squint his eyes comfortably.

But looking at the condensation speed of the milky white liquid, such a small drop is only afraid that it will take a day and a night to condense, and it is enough for a few people to use it, no wonder Bai Jin said that the earth milk cloud spring here is precious and abnormal. It can't be open to all disciples.

Suddenly. Chapter Mouse realized the problem. couldn't help but said with a panicked face: "Senior Brother Bai, the junior brother just thought, you said that this place is so precious, not all disciples can come to soak it, if the master finds out, wouldn't it be that the junior brother's life will be gone?"

Bai Jin seemed to have expected him to ask such a question, and asked with a slight smile: "Senior Brother Zhang, let me ask you a question. If you don't have the help of this Milk Cloud Spring, with your qualifications, how long will it take to break through the foundation building period?"

Zhang Mouse hesitated for a moment and replied: "If it weren't for Senior Brother Bai's elixir to help, plus this Milk Cloud Spring, it is estimated that Junior Brother would have to have ten years of hard cultivation!"

"Oh, is ten years of penance enough?" Bai Jin looked at him playfully.

Zhang Mouse was slightly stunned, and then smiled bitterly, "Junior brother is talking big! Don't hide it from Senior Brother, since entering the tenth layer of Qi refining, Junior Brother's cultivation speed has greatly decreased. It seems that there is a huge bottleneck, and sometimes it takes a month to cultivate a little bit of true qi. Honestly. Ten years of penance is just an estimate, maybe longer than that. ”

Bai Jin nodded: "Well, you're telling the truth." Let me tell you, this is the most difficult stage of qi condensation in the entire qi refining period, at this time, the cyclone growth in the monk's dantian becomes extremely slow, and more often it is a compressed cyclone, so that the cyclone turns from a gaseous state to a cloud state, and the middle will be filled with fine liquid beads. After the condensation qi is full, you can try to break through the foundation building period and completely compress the true qi in the cloud and mist state into liquid, which is the 'foundation building'.

In this way, the foundation building is actually divided into two steps, one is the compressed cyclone in the early stage, which turns the gaseous true qi into a cloud and mist state, which is what you are experiencing now, and it will only start after about ten layers of qi refining;

The whole process is extremely difficult, once you make a mistake, the light will be a fall, the heavy will be the destruction of the dantian, and you will never want to build a foundation for the rest of your life! If it weren't for the great talent of the body, or the great opportunity, this foundation building level can card people for a lifetime!

"For a lifetime?" Zhang Mouse stuck out his tongue in fright.

"That's right, it's for a lifetime, and I didn't say much about it. If you think about it, all the disciples in the sect have a chance that there are five or six out of ten disciples who can refine to the late stage of qi refining. And among all the disciples in the late stage of Qi refining, less than one in ten can break through the foundation building. Don't look at our Yunwu Peak, it seems that there are not many disciples and there are eight foundation building monks, that is related to the cruel elimination system formulated by the master, each batch of new disciples enters, and the one who survives in the end is one out of twelve.

Our eight foundation-building monks were also divided into seven or eight groups of disciples, and they stood out little by little. In other words, each batch of disciples, in the end, can successfully build the foundation, only one and a half, junior brother, you can be regarded as the best in this batch, and that Lei Hao. The possibility of the two of you breaking through the foundation building is very great, and you are also loyal to me Bai Jin, I don't cultivate the two of you well, who else can I cultivate?"

After Bai Jin finished speaking, Zhang Mouse was surprised and delighted, and gave up his hand again and again, thanking his senior brother for his promotion and cultivation, looking at him like that, he already had a full understanding of the difficulty of breaking through the foundation building.

Seeing that the fire was sufficient, Bai Jin smiled slightly and said: "So, it is so difficult to build a foundation, if you build a foundation a moment earlier, you will have the advantage of building a foundation a moment earlier, if you really cultivate for ten years and then build a foundation, then your muscles, bones and blood will be even weaker than now, which will have a great impact on your future cultivation and advancement!"

This Milk Cloud Spring is a great opportunity for you right now, and it just so happens that now in the third year, the number of powerful ghosts in the entire Extreme Yin Cave has been limited, so I can take you in secretly at the risk of Master's heavy order. Otherwise, even if I wanted to bring you in, you wouldn't be able to come in!

In this way, if you are really worried that the master will find out if you delay for a long time, then you can only soak it for half a day, and then I will give you a Tsukidan, and you will be enough to try to break through the Tsuki. Come on, come on, you hide here, even if anyone passes by, it's hard to find you. ”

Bai Jin lured and coaxed, and even found a Zhuji Dan that was enough for all Qi refining cultivators to break their heads, and finally coaxed Zhang Mouse to cry gratefully, and obediently hid in a remote corner of Dilu Cloud Spring, quietly absorbing this pure Heaven and Earth Yuan Qi.

This is also a huge temptation that is difficult for Zhang Mouse to resist Zhuji, once Zhuji Shouyuan will increase by a hundred years, and the strength of qi and blood and true qi will be doubled, and his strength can be doubled, how can he resist such a big temptation? Moreover, from his words and deeds, he can also see that Bai Jinsheng has a rebellious heart, and he is not so loyal to his master Situ Jin.

Since Bai Jin dared to take him to steal into the fifth layer of the Extreme Yin Cave, it was already tantamount to disobeying the master's orders, Zhang Mouse had long known it, and he also pretended to be guilty of his master's kindness, but in fact, he was just covering his ears and stealing the bell.

When Bai Jin saw him enter, the corners of his mouth couldn't help but put on a sinister smile, and he sneered in his heart: "Hmph! Fool! If you don't wait for that person to come and bathe, how can this place be defiled by garbage like you?"

He swept around, looked out through the smoke, and seemed to see a slender figure in white approaching, and then took off all his clothes and immersed himself in the milky white water.

His eyes were hot, and he couldn't help but breathe rapidly, and it took a long time to calm down, and he reached out and took out a small black needle as thin as a cow's hair from his arms, and when he raised it to his eyes, he saw that the tip of the needle glowed with a faint blue light, which looked very terrifying.

"Hmph, as long as you pierce this Nine Ghost Evil Needle that controls the divine soul into your mind, you will have to listen to me obediently......" Bai Jin looked at the empty pool at the moment with a blazing gaze, and muttered to himself. (To be continued......)
