In a quiet room on the second floor of Tianji Pavilion, Yun Yifei and Mu Qing sat face to face.

"Some time ago, I went out to collect spirit grass and killed two Soul Refining Sect cultivators, and I accidentally found this jade slip. Mu Qing said.

Yun Yifei was holding a jade slip in his hand, which contained the news that he was wanted and a portrait was engraved, he naturally knew the reason, and then said: "I killed a Soul Refining Sect monk before, and its elder seems to be a ...... in the late stage of foundation building."

"It seems that your traces should be exposed, there have been a lot of Soul Refining Sect cultivators in this market recently, and there are also cultivators in the foundation building period, I haven't seen anything to buy, and I don't go out on a mission, I think I should have come here for you." Mu Qing said,

Yun Yifei was surprised in his heart, he didn't even have a chance to resist in the face of the foundation building period monks, but after thinking about it, his identity should not be revealed, otherwise he would even be tired of Tianji Pavilion.

"Don't go out, they don't dare to mess around in this city. Mu Qing frowned and said.

"It's not a way to shrink like this, but when you leave, you have to give the Soul Refining Sect some color. Yun Yifei said hatefully.

"Don't act rashly, your cultivation is not enough. Mu Qing hurriedly said, for fear that Yun Yifei would be reckless.

"Don't worry, I won't risk my life, I still have a few sets of killing formations, I believe I can deal with the monks of the foundation building period. "The formation can deal with the fourth-order demon beasts, and naturally it can also deal with the foundation building period monks.

"Then you have to plan carefully, the monks in the foundation building period are not so easy to deal with, if there is any movement, remember to call me, I will see that their gang is not pleasing to the eye. Mu Qing said.

"You practice this kind of exercise to change your body shape and appearance first, and don't bother you anymore. Yun Yifei was silent for a moment before speaking, and then took out a jade slip.

There are also a lot of exercises to change the appearance in the market, but Mu Qing didn't care about these, but at this time it was different, the divine sense penetrated, and found that the grade of this set of exercises was not low, so he put it away, and after a few words, he took his leave.

"By the way, Fang Zitong officially went to the Jiang family to propose marriage, and also gave a dowry, and after the Elixir Valley was opened, he went to marry, it seems that this matter is settled. Mu Qing left a sentence before leaving.

"What about Senior Sister Yuchen?" Yun Yifei asked.

"Yuchen went back to the family to fight for the head of the family, and he didn't think it would be as he wished, after all, the head of the Jiang family accepted the dowry. Mu Qing sighed lightly and said, shook his head and walked out.

Yun Yifei felt as if something was breaking in his heart, his mouth was full of bitterness, he didn't know if he liked Jiang Yuchen, he only remembered that when Jiang Yuchen offered to go with him, he was full of joy.

He didn't know why he felt particularly uncomfortable now, after all, Jiang Yuchen and him could only be regarded as acquaintances, and he hadn't had more contact, and he couldn't help but think of Jiang Yuchen who loved to laugh at the beginning, laughing so easily, cleanly, and cleanly without any thoughts.

Now Jiang Yuchen, even if he laughs, he is haunted by a faint sorrow, thinking of this, Yun Yifei's heart seems to be held by an invisible hand, and it is indescribably uncomfortable.

After a while, he found a reason for his discomfort, the things he liked were deprived by others, he wasn't sure if he liked Jiang Yuchen or not, but he was sure that he liked Jiang Yuchen's clean smile, and now he was deprived by Fang Zitong.

In this way, he naturally hated Fang Zitong.

Yun Yifei sat quietly in the chair, his eyes narrowed slightly, his brows furrowed slightly, and he was calculating.

After a long time, Yun Yifei's face gradually calmed down, put on a hat and walked out of the Tianji Pavilion, went straight back to the cultivation stone room, and began to cultivate.

In the blink of an eye, the rest of the month flew by.

Yun Yifei had just advanced to the twelfth layer of the Qi cultivation period, and the restrictions of his body were opened, and the total amount of spiritual power had increased a lot in this month, and at this time, it seemed that he had also touched the limit of the dantian, and the significant cultivation effect brought by the advance tended to be normal.

"Even with the aid of pills, it is difficult for you to have obvious effects in cultivating like this. Yun Yifei was just about to swallow a jade dew pill, when a somewhat old voice sounded, it was the crocodile that existed in his dantian.

"Do you have any good suggestions from the seniors?" Yun Yifei asked happily.

"In addition to the auxiliary conditions, the speed of cultivation mainly depends on qualifications. Jiao Crocodile said.

"Senior, you tease me......" Yun Yifei was speechless for a while, isn't this equivalent to nonsense, he knows that his qualifications are average, and he is a three-attribute spiritual root.

"Qualification is mainly determined by the spiritual root, the more spiritual root attributes, it means that the more complex the spiritual root, the slower the absorption of spiritual energy, which involves the purity of the spiritual root, a single heavenly spiritual root has the highest natural purity, and the fastest speed of absorbing spiritual energy, theoretically speaking, the cultivation effect of your three attributes spiritual root is equivalent to one-third of the cultivation effect of the heavenly spiritual root, in fact, it is more than that. Jiao Crocodile said.

"Your body has fused a trace of my purple mist essence, and the biggest characteristic of purple mist is absorption, but your spiritual root is not powerful enough, so you can't absorb spiritual energy more quickly, so relying on pills to assist you has some cultivation effects. The crocodile continued.

"Then what can be done, the spiritual root can't be changed. Yun Yifei said with a sigh.

"The spiritual root cannot be changed, but it can improve the purity. The crocodile said simply.

"Cleansing Pill", Yun Yifei exclaimed, he remembered that he had obtained a lot of pills from Elder Li's storage bag in the Dan Dao Sect, including the Cleansing Pill, but he remembered that those pills were all high-level, and at least they had to be taken in the later stage of foundation building.

"This is something that can only be taken by a monk in the late stage of foundation building, even if you can help absorb some of the medicinal power, but I'm afraid that the physical fitness of a monk in the Qi cultivation period can't withstand the impact of this medicinal power. Yun Yifei said, thinking that the crocodile could also absorb the medicinal power of the elixir.

"What do you think? I don't absorb all the pills, and I don't need to refine the spiritual root. Jiao Crocodile said.

Without waiting for Yun Yifei to speak, Jiao Crocodile continued: "I can control the speed of the dissolution of the medicinal power, but it is also painful to refine the spiritual root, you have to be prepared." ”

"What do you need to prepare?" Yun Yifei said with some confusion.

"Mentally prepared. ”

"Uh, okay", Yun Yifei was speechless for a while.

Pouring out a cleansing elixir, Yun Yifei swallowed it after looking at it for a moment, he knew very well the difficulties brought by low cultivation, and had the opportunity to change his own conditions, how could there be any reason to refuse.

At the entrance of the Washing Spirit Pill, the purple bead released a purple mist to wrap the pill and drag it directly into the dantian, at this time Yun Yifei felt a medicinal power seeping out, and then seeped into the depths of his dantian, this medicinal power was like an awl, drilling the dantian, and the pain like scraping bones hit, making it unbearable for Yun Yifei, who was mentally prepared.

Yun Yifei gritted his teeth and insisted, sweat instantly wet his clothes, the spiritual roots were in the depths of the dantian, under normal circumstances, even if he looked inside, it was difficult to find, only when he was cultivating, he found that three thin lines of different colors were shining, that was naturally the three spiritual roots, at this time he felt that the three spiritual roots were as if they were being scraped with a knife, although it was only a few breaths, but it was enough to make him to the brink of collapse.

The clear pain always continued, and there was no weakening in the slightest, Yun Yifei always gritted his teeth on the verge of collapse and persevered, although it was only half a pillar of incense time now, he felt as if half a month had passed.

As soon as the pain weakened, it disappeared instantly, and before it was too late to enjoy it, another wave of medicinal power gushed out, and a clear sense of pain came again, so I had to continue to grit my teeth and persevere.

"Wait for ......", when the medicinal power disappeared, Yun Yifei wanted to let the crocodile wait before releasing the medicinal power, but he didn't expect that the pain would continue to come after only spitting out one word, and even moaning under the pain could cause collapse, let alone spitting out words clearly, so he had to grit his teeth and insist.

"Wait for ......", no medicinal power lasts for about half a pillar of incense, only two chances Yun Yifei didn't have time to speak, the pain swept over again, if he could speak, he wanted to say a dirty word.

The fourth time, Yun Yifei gritted his teeth and insisted, and did not try to stop the crocodile again.

The fifth time, although it was only pain in the dantian, he felt every inch of muscle in his body tremble, and he didn't know how long he could hold on, but he persevered.

After the fifth medicinal power disappeared, until a few breaths later, the pain did not appear again, Yun Yifei felt that his body returned to himself, he knew that this was the exhaustion of the medicinal power, so he lay back weakly, as if he had collapsed, panting heavily, and the futon under his body was also soaked with sweat.

After a while, Yun Yifei turned over and sat up, running the exercises to absorb the aura, eager to try the effect after washing the aura, and he could indeed feel that the speed of absorbing the aura was a little faster, but it was only a hint.

Yun Yifei felt a little disappointed at first, but after thinking about it, this is a permanent increase in the speed of absorbing spiritual energy, which will definitely help his cultivation in the future, this is only the effect of taking a pill, if it continues for so long, it is also possible to achieve the cultivation effect of the Heavenly Spirit Root.

The more Yun Yifei thought about it, the more excited he became, so he took out another pill, and after being silent for a moment, he gritted his teeth and swallowed it, since it was good for cultivation, what was it to bear a little pain: "Senior, here." ”

In fact, there was no need for Yun Yifei to remind him, after the pill was entered, a purple mist pulled it into the dantian, and continued to release the medicinal power in five times, which was also the limit of Yun Yifei's ability to endure pain.

In this way, while Yun Yifei was suffering in the stone room, the purity of the spiritual root was also slowly improving.
