Lu Cheng's internal strength was already at the peak of the third layer, and during this time, he had to fight with the three apes for at least four hours every day. As his comprehension of the plum blossom palm knife became deeper and deeper, he made great progress in both his comprehension of the palm knife and the improvement of his internal strength.

At this moment, Lu Cheng sensed that he had reached the three-story barrier. He only felt as if he was only a little bit away, as if the last layer of window paper needed to enter the fourth floor with a light poke. But his internal strength, like the end of a strong crossbow, is always a little bit worse when he is about to pierce this layer of window paper.

Lu Cheng kept running the mental method, and the internal strength in his meridians became more and more abundant, and as the internal strength kept gathering, the meridians began to be forcibly expanded like sausages. But the speed of internal energy began to slow down. Lu Cheng used all the four induction forces on the opening path of the internal strength, and the induction force continued to expand the meridians, so that the internal strength behind could run faster.

The induction force opens the way in front of the mountain, builds a bridge when it encounters water, and the internal strength behind it is like a rolling torrent, filling the meridians again to be full and full. This cycle repeatedly, tirelessly, hitting the final barrier again and again.

Suddenly, Lu Cheng sensed a roar from his brain, and he felt that all the meridians suddenly expanded on their own. And the induction force and internal strength, without any effort, can run happily in the meridians. Lu Cheng was overjoyed, he knew that he had finally broken through the barrier of the third layer of internal strength and entered the fourth layer of internal strength!

If at this moment, Lu Zhong knew about Lu Cheng's cultivation, I don't know what kind of excitement he would become? Song Jiazhuang had a four-story Song Kaixuan, as if he had become the number one family in Datong County, and he got carried away all day long. But what about Lu Cheng, he had only started cultivating for a few months, but he had also entered the fourth layer. If his cultivation speed is known, I'm afraid that others will see him as a monster, or at least an anomaly. Because this kind of speed is no longer possible for normal human beings.

Lu Cheng didn't think so much at this time, and he didn't stop there, he still used his inductive power to guide his internal strength and consolidate the meridians that had just been expanded. And let the internal strength gather at the dantian, which was originally just a foggy dantian, but now it has become more dense. And his induction force was divided into eight strands at once, and these eight induction forces were no longer used as an open road, but constantly supported the expanded meridians in front, so that the internal strength in the back could run faster.

When Lu Cheng slowly opened his eyes, he didn't know how long it had been. When he advanced just now, he had long forgotten the time, and only thought about consolidating the fourth layer of internal strength. At this time, it was dark in the valley, and the fire in front of him had long been extinguished, and the pork had been scorched. He looked up into the valley and saw a sky full of stars, apparently already night. But he didn't know if it was tonight, or the next day, or the third night.

Looking at the stars in the sky, Lu Cheng suddenly entered a state of dark vision, and the sensing force at the center of his eyebrows merged into a strand, broke out of his body, and threw it into the starry sky. The newly increased sensing power, after breaking through the body, jumped happily. When the sensing force crossed the gap in the valley, Lu Cheng seemed to follow and penetrate himself. He could even sense Taniguchi's situation.

At that moment, Lu Cheng seemed to have discovered two apes. Taniguchi was at least hundreds of zhang away from his current location, and he never thought that he could sense Taniguchi's things. It may be because the eight inductive forces are combined into one strand, and the ape is very familiar with himself, so the good inductive power sent back such a message to Lu Cheng, which cannot be regarded as Lu Cheng's induction.

Lu Cheng immediately withdrew the sensing force, although this sensing force broke through his body on its own and shot out of the starry sky. But as soon as Lu Cheng closed his eyes, this inductive force would immediately retract into his body. Lu Cheng released the induction force, and the eight induction forces could perceive everything around him. Although it was already the middle of the night, Lu Cheng did not stop at all.

During this time, he had already made the three apes his friends, and the apes seemed to have a crush on him. He used his Vertical Technique and quickly climbed upwards in the darkness. Lu Cheng's speed is very fast, he is now the fourth layer of internal strength, and his strength has increased several times compared to the third layer. Some of the movements of the Vertical Body Technique, which he used to be very difficult to do, but now he doesn't have that feeling.

The valley is hundreds of feet high, and some of the rock walls are so steep that it is very difficult for even apes to climb up. But when Lu Cheng climbed up, there was no sense of stagnation. With such skills, even Song Kaixuan is beyond his reach.

Although Lu Cheng did not practice the body technique as long as Song Kaixuan, he worked harder. The difficulty he added to himself, if he put it on Song Kaixuan, even if it was only casually increased, Song Kaixuan would not be able to cope with it. And Lu Cheng added four or five difficulties to himself at the same time, and it was not accidental that he could have the results he has now.

Lu Cheng soon arrived at the mouth of the valley, and he had the power to help and soon found the ape. But instead of three, there were only two, two apes and three apes, and the big ape was gone! When Lu Cheng approached, the ape also spotted him, but instead of coming, he kept squeaking towards the valley.

There are starlight on the top of the valley, and I can still vaguely see a little bit of affairs. Lu Cheng followed their gaze and threw his sensing power over. Although his sensing power was now eight feet away, there was no abnormality other than the discovery of a hole in the valley wall. Could it be that the great ape entered this cave?

Lu Cheng was just about to go down, but the second ape and the third ape seemed to have seen something frightened, and they actually pulled Lu Cheng and didn't let him go down.

"The big ape entered this cave?" asked Lu Cheng.

The two apes seemed to understand Lu Cheng's words, and nodded in unison. Something had already happened to the big ape, and they didn't want Lu Cheng to have an accident too. Lu Cheng regarded them as friends, why didn't they regard Lu Cheng as friends.

"Is there danger inside?" Lu Cheng asked again.

Their dots are like chickens pecking rice.

"It's okay, I'll go in and have a look. "Lu Cheng has already established a relationship with them, and if he doesn't find the whereabouts of the big ape, I'm afraid he won't be at ease.

Lu Cheng now had the power to sense the distance of eight zhang, and he believed that even if there was any danger in the cave, it would not be difficult for him. Moreover, he is also confident in his own body technique, even if he can't save the big ape, it should be no problem to escape, right?

Originally, the sky was already very dark, and with a little starlight, I could only vaguely see the entrance of the cave. The entrance of the cave was five or six zhang away from the top of the valley, which was not difficult for Lu Cheng. He jumped from the top of the valley, and when he was about to reach the entrance of the cave, he turned around in the air, and the man reached the mouth of the cave.

This cave is very big on the outside, but it is getting narrower and narrower on the inside, and even Lu Cheng can only walk by bending over. When he jumped down, Lu Cheng used the Turtle Breath Technique, he didn't know what was going on in the cave, and it was safer to use the Turtle Breath Technique. Once inside the cave, he casts his senses. When he walked in more than a hundred feet, the space began to grow, at least he could stand normally.

At the same time, Lu Cheng also noticed the movement, and there was a terrifying creature looking at him inside!
