In the deep and invisible cavern, a huge figure is moving up and down in it. With the grappling technique, he sucked the big stones on the walls of the cave, and pushed down again with the repulsion technique, and in a few bounces, he had already rushed out of the cave that was more than 100 zhang deep. Beyond the entrance of the cave, there was already a mountain of earth and rocks.

——In Kunpeng's body, it only took Yue Yu two days to engrave this Capture Technique and Repulsion Technique runes. And the reason why it is so easy is because of the innate aftermath, Yue Yu's auxiliary intelligent system's computing power has suddenly increased by more than ten times. What used to take a month to calculate and derive can now be done in just two or three days.

Yue Yu was also deeply vigilant about this, after all, it was his own internal cultivation that was fundamental. These miscellaneous studies can be studied, but they can only be in an auxiliary position, and they cannot affect one's own practice.

In addition, the sigils he had engraved in that soul stone had reached two hundred and thirty. makes Kunpeng's reaction extremely sensitive. But then he couldn't carve it anymore, not because of his own lack of soul power. Since his innate time, the power of his divine sense has more than doubled in these days. And this momentum of growth is far from seeing signs of stopping.

- The difficult thing is that these runes, Qin Yue has not learned them because of his lack of soul power, and his own exploration on his side is too time-consuming.

After stepping on the ground, Kunpeng took off the large basket hanging behind him and dumped it on the ground with a sharp movement. After pouring out all the mud and rocks, he jumped into the cave again.

In fact, Yue Yu's original idea was to use the Xuanxue vine and then use the principle of carrying the pole to get these excavated earth and stones out of the hole. However, it was later found that both the consumption of spiritual power and the speed were not very ideal. It's better to use repulsion like this, and Kunpeng himself climbs up with the basket. The consumption of that demonic power crystallization was at least more than twice as much as the former.

"Brother Xiao Yu, do you really want to dig a tunnel to dig into?"

In the control room, Yue Bingqian was covering her mouth with a pale face, she didn't have the cultivation like Ran Li. And Kunpeng's bumps up and down the feeling of emptiness have made her feel extremely disgusting.

In fact, this guess was originally asked by Ran Li first. Yue Bingqian was still a little unbelieving at first, but looking at this, she couldn't believe it anymore.

"Brother, it seems that there are still sixty miles from the mountains over here, right? It took a whole day just to dig this hole of more than 100 zhang. I don't have to be able to hide it from them—"

Yue Yu snorted coldly and continued to dig down with the black iron heavy sword in his hand. The ground here is hard and full of rocks, which can be a bit difficult to excavate.

- But fortunately, if the ground is really soft, he is afraid of a landslide, and he really doesn't dare to start digging to such a deep place.

After shoveling hard a few more times, suddenly Yue Yu felt that a sword suddenly pierced the air, and the figure of the puppet also fell down due to the wrong force.

However, at this moment, Yue Yu was not surprised, and tried to control Kunpeng to maintain his balance when he fell, and hit his feet with a repulsive technique. In the midst of the exclamations of Ran Li and Yue Bingqian, the puppet quickly descended with the tumbling dirt. However, after only about 30 zhang or so, it had already landed firmly on the ground, causing a splash.

Just as Kunpeng stabilized his body, Yue Yu immediately ran to the crossbow arrow on the puppet's head and looked outside, and then a smile escaped from the corner of his lips.

What appeared in front of him was a large underground river, about forty zhang wide and seven zhang deep, just reaching Kunpeng's chest. The river was very fast, but in an instant, it had washed away the already muddy Kunpeng shell.

- Sure enough, just as he had calculated, there was an underground river beneath this small mountain range.

"No wonder the young master must have Kunpeng covered with a few more layers of animal skins a few days ago!"

Also with Yue Yu rushed here, Ran Li also understood at this time, and his face was happy. However, with his current level, he can only sneak for about two or three hundred meters at most. I heard that it is much stronger after being born, but it is only a distance of four to five miles, and it cannot reach a depth of more than two hundred zhang.

However, Yue Bingqian cared about the other side, and her eyes flashed when she looked at Yue Yu: "Brother, how do you know?"

Yue Yu shook his head slightly, he really couldn't explain this clearly. For a few days, I spent the third year of junior high school observing the mountain range trend, the whereabouts of the glaciers at the top of the mountain, and then surveying the geology of the area. Then the auxiliary intelligent system is used to form a whole terrain model map, which is judged.

- But I can't tell my sister and Ran Li about this.

Kunpeng walked all the way, only to see that the front was wide and narrow, and it was about 100 zhang wide. When it is narrow, it is only seven or eight zhang wide. Fortunately, the top of this river cave is still relatively high, and the huge body of the puppet can actually pass freely in it.

After walking for about forty miles, the eyes of several people suddenly opened up, and this was actually a small underground lake. On the other side of the lake, there is a pier made of white marble. There were two small boats next to it, but they were capsized for some reason. And from the pier and then up the stairs, about forty feet high, there was a vermilion wooden door that closed it.

"Could it really be that it's really a loose cultivation cave left over from my predecessor?"

Ran Li's eyes showed excitement as soon as he saw the pier. But in an instant, he felt that something was wrong.

- Build a pier in this underground lake, and dig it so deep. How could it be that the manpower and material resources used by him could be accomplished by a single casual cultivator? Even if it was really a casual cultivator with no sect and no sect, then this person's power would inevitably be extremely great!

How could such a large-scale cave mansion be unknown and only now discovered?

Yue Yu's pupils shrank slightly, looking at the fragments of the two completely shattered ships, as well as the scattered wooden planks in the small lake, his heart was full of alarms. In addition, there are the white marble stairs and docks, although there are no scars, but on both sides, they are covered with huge whip marks, and I don't know what caused it, he first walked to the shore of the lake with his divine sense, and then sensed the lake with his divine sense. However, there is a lake to block it, and his mental power is greatly affected. Neither spiritual nor spiritual perception could reach the depths of the lake.

Yue Yu frowned, feeling lucky, judging from the creatures in this lake, they should not be able to raise any too high-level demon beasts, at most, they were only at the level of the sixth order. However, the lake is too calm, but it is also a little suspenseful.

He cautiously walked along the wall of the cave in the direction of the dock. Along the way, try to control the movement of the puppets to the weakest degree.

And when the pier was in sight, Ran Li was the first to jump off the top of the puppet's head. However, he has always been clever, and at the moment he is just watching from a distance, but he is not close to the dock.

"Hey, what a powerful demon beast, I don't know if it's a sixth-order or a seventh-order-"

- I didn't feel anything when I looked at it from a distance just now, but when I got closer at this moment, I could feel the horror of the whip marks. actually smashed those stone walls that were as hard as iron into more than ten zhang. And vaguely recognizable from the latest traces, on which was struck was a strip about three zhang wide and more than ten zhang long, and covered with scales. It was somewhat similar to the ten-colored lizard, but that fifth-order primordial beast was far from having such strength.

And on top of the rock wall, there was a large amount of dried up dark red blood.

The three of them were all shocked, and while they were deeply afraid of the demon beast, they were also curious about those white marble steps. What kind of force could make these stones, which are just ordinary stones, so hard as they are, unscathed by such an attack?

Yue Yu frowned slightly, and after muttering for a long time, he started to move, he first sprinkled some Xuanxue vine seeds around Kunpeng. He has been using his spiritual power to give birth to it until he clings to the ground. Only then did he indulge Kunpeng again and retreat a kilometer away. Then shoot an arrow with a Bingyi bow to test the surname.

But the next situation once again shocked several people. As soon as the red-eyed eagle bone arrow approached two feet of the white marble steps, there was an invisible force that firmly blocked it. Then, in the next instant, countless extremely sharp wind blades rolled up wildly, splitting the arrow that was still hovering in the air into pieces. And after that, there was a counterattack, and the periphery of the dock shone with a strong electric light, enveloping the Baizhang space. In addition, there were dozens of wind blades that shot towards this side, and the speed was extremely fast.

Yue Yu hurriedly urged those Xuanxue vines to stretch out high, stopping in front of those wind blades, and he retreated hundreds of steps one after another before he avoided this catastrophe.

And by the time it all came back to calm, all three of them were covered in cold sweat.

"Brother Xiao Yu, I'm afraid something is wrong. Is this really just a scattered cave house?"

Yue Bingqian's face was pale, full of palpitations. With the power of the two secret methods of wind and thunder just now, even the innate powerhouse can only die!

And Yue Yu also fell into deep thought, recalling that he used a telescope to observe the conversation of those people. The information he obtained several times through the comparative analysis of the lip language technique and the auxiliary intelligence system was that within this small mountain range, it should be a cave mansion left over from the spiritual and void fusion period that was good at refining medicine.

- But where is the prohibition of such power that ordinary casual cultivators can have?

Unless, it is the people themselves, they don't know the details of this place! If not, I am afraid that the people who come here will not only be some loose cultivators who do not enter the stream!
