Watching the crack slowly disappear and the sky return to calm, Zhou Yifeng felt a sense of loss rise in his heart!

After a while, with a long exhale, to clean up his emotions, Zhou Yifeng took out the communication bead, sent a message to Xiao Qingwen, and walked into the cave.

He decided to retreat here, and this time, he wanted to attack the middle stage of foundation building to prepare for the great competition of the sect in half a year.

Although he possessed innate exercises, he did not dare to underestimate the genius of the Jade Cang Continent, after all, his cultivation time was still short, and he was still in the early stage of foundation building. He remembered that Zhang Chengfeng had said that Duan Lang of the Blood Knife Gate and Shen Tuyu of Tianqian City were both able to confront the Jindan Monk head-on!

And his biggest reliance is the powerful sea of consciousness and the thunder soul thorn. But if he encounters an opponent who is also strong in the knowledge of the sea, he may not have any advantage! Therefore, he must improve his cultivation in order to gain something in the great competition of the sect and get the opportunity to enter the Jade Cang Secret Realm!

For the Jade Cang Secret Realm, Zhou Yifeng is still full of expectations, it is an ancient ruin! Not to mention the immortal weapon, the immortal method, even if you can get the best spiritual weapon, you can also increase your strength!

After tidying up the cave a little, he thought about it, walked out of the cave again, came to the crack in the canyon, moved a boulder to block the entrance, and arranged a concealment formation to hide the traces, and then returned to the cave.

After a few simple words of explanation to the tadpole, Zhou Yifeng sat cross-legged in the middle of the arranged spirit gathering array, and the Tianyan Thunder Trick ran quietly.

Suddenly, the spiritual energy in the valley surged, constantly gathering on the top of the cave, forming a vortex of spiritual energy, continuously entering Zhou Yifeng's meridians, and being turned into a silver true yuan by the Tianyan Thunder Technique!

In the middle of the impact foundation building, this begins!

Fortunately, this valley is extremely hidden, coupled with its location in the deep mountains, and because of the entrenchment of the Blood-Eyed Lion before, there is nothing to disturb it, which allows Zhou Yifeng to cultivate without distractions, day after day.

In the small valley where cultivation has no time and is inaccessible, as time flows quietly, some small animals living here have gradually become accustomed to the aura vortex in mid-air and the big tadpoles that occasionally "croak" twice, and no longer pay attention to it. In the valley, its original natural ecology has been restored.

A month later, Zhou Yifeng entered the middle stage of the third layer of foundation building, but he didn't get up, and he was still absorbing the aura pouring in from the top of his head in refining.

Two months later, it entered the late stage of the third floor of the foundation.

When Zhou Yifeng was in retreat for nearly 100 days, the true yuan in the meridians was already infinitely close to saturation, reaching the realm of consummation of the third layer of foundation building!

At this time, the entrance of the cave was completely covered with weeds, and some of them even stretched into the cave.

Zhou Yifeng stood up, a few wind and thunder blades swept out, cleared the weeds at the entrance of the cave, and came to the valley, he needed to relax, adjust his mentality, and prepare to attack the fourth layer of the foundation.

As if sensing that Zhou Yifeng had finished his cultivation, the big tadpole instantly appeared in front of Zhou Yifeng, and "quacked" twice.

Looking at the big tadpole that appeared out of thin air in front of him, Zhou Yifeng touched its head, he hadn't seen it for three months, except that his body had grown to about two feet, there was no change in the others, and it was still gray and not slippery. After thinking about it, Zhou Yifeng couldn't help but smile secretly, after all, it was only more than three months old, and he was a little anxious!

After playing with the tadpole for a while, Zhou Yifeng caught a hare, and after the barbecue, under the vigilant gaze of the two soul-seeking rabbits, he ate it separately with the tadpole.

He hadn't eaten for several months, and half a hare also made Zhou Yifeng feel very satisfied.

After waving his hand to let the tadpole play by himself, Zhou Yifeng sat cross-legged and began to adjust his state, preparing to break through.

Half an hour later, Zhou Yifeng had no distractions, took out hundreds of high-grade spirit stones from the ring, and put them beside him, his mind moved, and the Tianyan Thunder Technique instantly started and ran at full strength, impacting the middle stage of foundation building, starting!

Suddenly, the aura within a radius of a kilometer was extracted, and the valley was like a whirlwind, and the aura bee chrysalis came, and a huge aura vortex beyond the three zhang radius was formed, making a low "woo" sound, and the rich aura was poured straight to the top!

With the transformation of the aura, the true element in Zhou Yifeng's meridians increased again, gradually expanding, and constantly washing the slightly rising meridians and acupoints. When the surging true element reaches a threshold, an obstacle appears in the induction, and the foundation of the mid-stage diaphragm appears!

The mind controls the true element, after two consecutive impacts, there is a faint feeling of loosening, holding the two spirit stones in his hand, and between the rotation of his mind, a drop of liquefied true yuan in the dantian is transformed into a gaseous state, rushing into the meridians!

The meridians that had already risen slightly, due to the addition of the two newborn true elements, there was an instantaneous tearing pain! But Zhou Yifeng couldn't care so much at this time, controlling this huge true element, and crashed into the diaphragm!

There was a soft "click", and the diaphragm broke in response! The huge True Yuan found the pouring mouth and bubbled into the nascent acupoint, forming a new cycle! At the same time, there was a burst of emptiness in his mind, and his body seemed to have become lighter, and the feeling that it was several times stronger than the third layer of the foundation building made him can't help but let out a low roar! In the middle of the foundation building, he arrived!

After calming down a little, Zhou Yifeng once again restrained his mood and began to stabilize his realm.

Half a day later, when night fell, Zhou Yifeng stopped running on Zhoutian, and at this time, the meridians were full of true yuan and bubbling around.

In the dantian, the liquefied true element no longer appeared in drops, but with the refining of the aura, under the action of the thirty-five drops of liquefied true element, all of them were transformed into a liquid state. After all of them are transformed into liquid true elements, it is time for him to step into the late stage of foundation building!

After checking his Divine Sense, he found that the range had reached a radius of three hundred miles, and the space within the Sea Awareness Barrier had also reached a range of three thousand meters, and the clear light on the barrier was still flowing, protecting the Spring of Sea Knowledge!

After some induction, Zhou Yifeng felt that this stage of the retreat could end here. He planned to go back to the sect first, after all, he hadn't accompanied Xiao Qingwen for a few months.

That night, after Zhou Yifeng sent a message to Xiao Qingwen, he did not practice anymore, but slept well. This sleep was unusually sweet, and I even had a dream. In the dream, he returned to Earth, but there were no more people, so most of them were gone, which made him sad.

After waking up, Zhou Yifeng was silent for a while, he had been away from the earth for almost half a year, and he didn't know what was going on there!

Strength! All this requires strength!

At dawn, Zhou Yifeng glanced at the valley and decided to go back to the sect to accompany Xiao Qingwen for a few days, and then come back to cultivate, his original plan to relax was canceled due to last night's dream!

Leaving the big tadpole here, Zhou Yifeng stepped on his sword, and flew towards the location of the ironclad crocodile according to the direction given by Zhu Yuming.
