Wan Kai was busy refining the Qingfeng Sword all day long, and Yang Chen was also involved and had no time to find the source of fire, but after refining the three Qingfeng Sword, Wan Kai suddenly rested, saying that he was tired and needed to recover. According to Wan Kai's temperament, he will definitely refine all the Qingfeng Sword, and he can't stop until those spiritual materials are consumed, and this time it is completely beyond everyone's expectations. Although Yang Chen, Liu Shi and Mo Kongsheng were a little strange, they were also happy.

Yang Chen was even happier that he was finally freed from the busyness of refining. Wan Kai stayed in the room all day and closed the door, while Yang Chen wandered around Yan Yunfeng, looking for the source of the fire. Mo Kongsheng was the most diligent, staying in the house to concentrate on cultivation, Liu Shi did not cultivate well on Yan Yunfeng, and he also followed Yang Chen to play outside, but the search for days had no effect, and Yang Chen was also a little disheartened.

On this day, Yang Chen and Liu Shi searched for a long time but to no avail, and they had no intention of looking, so they looked for something strange in the valley to play. I accidentally found a snow-white hare, and I don't know if it was a strange beast or a spirit beast, but it looked like the meat was whirring, but I wanted to catch it and cook it. Before, the two were still chasing the rabbit with a playful mentality, but then they found that the rabbit was running too fast, which greatly surprised Yang Chen and Liu Shi, and the two used all their strength to catch up, but when they were about to catch up, they were drilled into a cave by the rabbit.

This cave is not very big, it seems that it can only accommodate one person to climb and drill into, Yang Chen and Liu Shi are also playful, and they drill into it regardless of it. After entering Ichijo, the cave suddenly grew larger, and was able to accommodate adults to walk upright in the cave. The rabbit had long since disappeared, but Yang Chen felt that there seemed to be a fire vitality in the cave, although it was not very thick, but there was a faint fluctuation of fire vitality.

"Is this strange?" Yang Chen had already discovered that the vegetation outside the cave was sparse and there were few spiritual materials. According to such a scene, it should be a lifeless being, but this cave is a strange and different scene.

Yang Chen and Liu Shi followed the cave all the way inside, the cave was winding, and gradually lava appeared, which seemed to be a karst cave. Moreover, the fluctuation of the fire vitality here is also gradually becoming stronger. The questions in Yang Chen's heart became stronger and stronger, and he became more and more curious about this place.

Liu Shi asked: "Senior Brother Yang, you can't be mistaken, right?" Liu Shi felt that there was nothing strange here, there was a rabbit attraction before, but now the rabbit can't be found, Liu Shi has also lost interest, and has a plan to go back. Yang Chen smiled and said, "Senior Brother Liu, you can accompany me to take a look!" Yang Chen's hopeful eyes made Liu Shi not easy to refuse, Liu Shi smiled innocently and said, "Okay." ”

Further inside, you can see a fork in the road, and you can see that the cave is a branch of the cave. The further you go in, the more space there is, and the more you see the hole in the fork. The fluctuation of the fire vitality became even stronger, and Yang Chen could already feel the fire vitality that was vague and diffuse in the cave.

"There's a fire energy. Yang Chen said in surprise. After they traveled more than 500 meters, they found a deep crack in the cave, and this crack seemed to be very deep, and they couldn't see what was going on below. If there is no fluctuation of fire vitality, it is diffused from here.

"I'll go down and have a look. Yang Chen glanced at Liu Shi and jumped down. Unexpectedly, this crack is not as deep as expected, and it is about a few tens of meters before it reaches the bottom. Yang Chen suddenly rolled down, and in this crack was actually a slope-like existence. After rolling down a hundred meters, Yang Chen stabilized his figure, and then slowly probed downward. There is nothing to be seen here, Yang Chen is just moving with his perception, but now Yang Chen's perception is much stronger, he can sense the existence of life within a thousand meters, and it is certain that he does not perceive any signs of strong life in the rift.

Yang Chen groped and walked slowly, this slope winds down, and sometimes a high platform appears, Yang Chen will jump down after perceiving it, fortunately, there is already a slope under the high platform, so he doesn't know how far he has gone down, and gradually there is a faint light appearing.

"Fire Vitality!" Yang Chen was surprised to find that the fire vitality here was already very rich, and these bright lights were produced by the convergence of these fire vitality. Yang Chen felt that the crack was even more blurry, he didn't know what kind of storage was underneath this, it was certain that there was a strong fire vitality here, Yang Chen thought to himself: If there is enough fire vitality, he will just fulfill his wish, and use this place to condense the vitality.

Yang Chen felt the difference in the crack, what he couldn't figure out was that this crack seemed to have no end, and it seemed that it had been two hours since he entered the crack, but all he could feel here was the change of the fire vitality, the deeper he went here, the thicker the fire vitality became, and now he already felt that the fire vitality was a little stagnant, but the fire vitality here was not so pure, and it would take a lot of energy to use it for cultivation, so he did not use the fire vitality here to cultivate, but kept exploring downward。

There was only Yang Chen's footsteps in the crack, and this footstep was even more lonely in the crack, and a faint sense of loneliness slowly floated in Yang Chen's heart. After walking for about five or six hours, Yang Chen finally saw a cave entrance, and all he saw in the cave was a patch of red, like clouds in the sky when the sun was setting.

"It's so spectacular!" Yang Chen couldn't help but marvel when he came to the entrance of the cave to look. It was a cylindrical pit, and I couldn't see how deep it was, except for the red fire that was tumbling in the pit, like a steaming cloud obscuring the vision. In the red fire qi, there was a strong fire vitality, and Yang Chen could feel that the more the fire energy in the center of the pit, the more refined it became, while the fire energy diffused around it was mixed and impure.

It's definitely good to cultivate here, but it's a pity that it's too far from the center of the pit. Yang Chen was a little regretful, just as he was about to sit down and cultivate at the entrance of the cave, he saw that there was a protruding rock on the wall rock opposite the pit, this rock was very strange, as if it was born on the rock wall, and it stretched into the pit for a long time, as if it was dozens of meters long. This is a good place to cultivate, but it's a pity that it's too far away to get by.

Yang Chen looked at the surrounding rock walls of the pit, and at this time, a line of fire suddenly appeared on the rock wall, like a flowing fire spreading on the rock wall, and as the line of fire extended, the wall rocks turned into rubble and fell one after another. Yang Chen fixed his eyes and saw that it was a rat with fire all over his body, this fire rat walked through the wall rock at will, sometimes appearing, sometimes disappearing, and in a short period of time, it actually pierced hundreds of small holes in the rock wall.

Yang Chen looked small when he was far away, but in fact, every hole was more than one meter. Yang Chen had a whim, if he could use these fire rat caves, he might be able to get through. Yang Chen looked at the cave where he stayed, and sure enough, he found that there were several small holes on the rock wall of the cave, and they were all rock walls close to the pit. Yang Chen was in the mood to try it out and drilled into a cave, this cave was about one meter long, Yang Chen was very uncomfortable when he entered the half-squat, but fortunately, Yang Chen's body was flexible and able to deal with it.

The cave turned around, some places communicated with other caves, Yang Chen drilled in and out of the cave, and from time to time could appear on the pit wall, so that Yang Chen could also refer to determine which cave could reach the opposite side of the horizontal rock. Hengyan looks very close, but it seems very far away when he walks through the cave, Yang Chen arrived at the top of Hengyan after two hours, this is the nearest cave, but it is also more than ten meters away from Hengyan, if you jump down, there is no guarantee that you can fall on Hengyan, if you miss, you will probably not be able to come back.

Yang Chen hesitated for a while, his heart was rich and dangerous, how could there be anything that he got for no reason, and his heart turned over and jumped down. What he cast was the ** of the fragrance of fallen leaves, which seemed to be very slow, which also gave Yang Chen an opportunity to adjust his body.

"Bang" Yang Chen happened to land on the edge of Hengyan, and he hurriedly stabilized his figure, if he was not careful, he would have to fall. "Huh. Yang Chen finally stabilized his body and couldn't help laughing. But at this moment, suddenly there was an empty foot, and the original stone rock suddenly fell off, and Yang Chen also went down.

"Pop" Yang Chen was very fast, and the moment he fell, his arm grabbed the corner of Hengyan. Yang Chen immediately felt that the rock horn in his hand was also loosening. The left hand quickly stretched out and grabbed Hengyan, grabbing it, but the hand was loose again. Yang Chen kept reaching out to grab the horizontal rock, but every time he grabbed the rock, it would fall off. He was like an empty robe hanging from Hengyan, his arms waving and constantly moving.

Yang Chen's mind was racing rapidly, he had already thought that this horizontal rock was already rotten in the scorching heat of the pit fire, and he had not thought of this before, so that he was in danger. He didn't grab his arm and jumped to the top of the rock, but this method worked, although he had grabbed most of the rock on the side of the rock, but he still climbed to the top dangerously.

It's just that when Yang Chen looked at it carefully, he couldn't help but chuckle in his heart, because before he knew it, he had reached the top of Hengyan. If he had reached the top before, he would have been very happy, but at this time, he couldn't help but feel a wave of fear, if Hengyan suddenly broke off, where would he still have a chance to live.

He slowly climbed to the center of the top of Hengyan and tried to retreat to the bottom of Hengyan, but there was a clicking sound under his feet, which frightened Yang Chen immediately.
