Coming to the light source again, Jiang Xingchen and the others stopped, although the dazzling light pierced his eyes and couldn't open them, he still wanted to check it. This light source has been here for an unknown number of years, and the light is still so strong, it must be a problem. And the light emitted can eliminate the effect of the mandala in the channel, which is really strange.

Carefully pressing his hand on the light source, Jiang Xingchen did not use the material detection array to check, worried that the vitality would be sucked away again, but silently used the method of breathing to feel the fluctuations of the vitality. Generally speaking, fluorescent stone is consumed because of the diffusion of vitality, and if you want to keep it bright for a long time, the only way is to replenish it. But until now, he didn't know how to replenish fluorescent stone. So he thought maybe he would find something here.

Sure enough, as his breathing method operated, the fluctuations of his vitality were clearly perceived. What made him different was that the energy in his perception was different from anything he had ever seen.

"What's going on?" Jiang Xingchen frowned, speeding up the speed of the breathing method, and the perception spread downward along the light source.

"Formation!" Just as he sensed the light source underneath, he felt several strange lines, which made him immediately think of the introduction control array in the high platform.

"It's not the Induction Array!" Jiang Xingchen forcibly suppressed the surprise in his heart. He felt that the Yuan Qi was attracted by the light source, but the transformed Yuan Qi was not a gathering Yuan Qi at all. It's a kind of vitality that he has never seen before.

"What kind of formation is this?" Jiang Xingchen continued to study along the lines, and at the same time corroborated with the formation in his body

"Boy, what are you doing?" The old man was a little impatient, and asked loudly, there was a white light here, and nothing could be seen, which was irritating.

"Don't talk, wait for me for a while?" Jiang Xingchen replied, and then let out an exclamation: "Found it!"

"What was found?" The old man asked again.

Jiang Xingchen ignored it, as if he hadn't heard it, his heart was full of shock at this moment, because he found that the formation under the light source turned out to be the Yuan Qi Fusion Array that he had just developed.

Although it is the same as the formation in the high platform, it is quite simple, and it is far less complete than the formation he developed. But here the formation is completely new to the transformation of vitality.

"It turns out that the function of the Yuan Qi Fusion Array is like this, through different transformations, and the fusion with different substances The formation here is simple, so can my complete formation transform multiple Yuan Qi and fuse with different things?"

Jiang Xingchen thought so, and the shock in his heart turned into expectation. Whether it is the formation of the high platform or the formation here, the effect cannot be compared with your own formation, and the function of your own formation must be greater.

"After you go back, you must study the role of the formation. Jiang Xingchen secretly made up his mind, this time he came to find the treasure, even if he didn't get the Dragon Blood Dragon Pill, it was worth it if he didn't subdue the divine beasts and dragonflies, he just knew that the formation could still be used like this.

"The vitality of this formation transformation can not only supply the source of light, but also eliminate the influence of the mandala. If you use a complete formation, I don't know what the effect will be. ”

Jiang Xingchen pondered while continuing to explore, and then found the colorful crystal. He secretly said in his heart: "No wonder there are colorful crystals outside the bat cave, it turns out that they are used as a source of power!"

"Boy, there's water over here!" The old man's voice sounded again. Jiang Xingchen ignored him just now, feeling bored, so he groped along the light source. As a result, puddles of water were found on both sides of the emitting light source.

"Oh?" Jiang Xingchen stopped breathing, he had already probed, there was no need to continue, the old man's discovery attracted him again.

"Come and see!" The old man greeted loudly.

Jiang Xingchen looked for the voice, and under the guidance of the old man, he really touched a puddle of water, and through the vibration of the water, he felt that there seemed to be a lot of fluctuations inside.

The light source was in the middle of the passage, and when they came, they jumped straight over, and they really didn't pay attention to either side.

Jiang Xingchen squatted down, ran the material exploration array again, avoided the development of light sources, and probed deep into the water source. He immediately noticed that there was something else down there. The mouth of the waterhole was only a meter square, but the space below slowly opened up, and the width of the front and back grew deeper and deeper, and finally formed a deep underwater passage, the length of which far exceeded the limit of what he could explore. And in it he found a lot of fish.

"Didn't you wonder where those fish came from, here's the answer!" Jiang Xingchen said.

The old man scratched his head, still a little strange: "How can there be so many fish here, where does it lead below?"

"It must have something to do with the sea, and there is no doubt that as for why so many fish come here, it is probably related to the fluorite light source!" Jiang Xingchen didn't explain much. In fact, so many fish should have been attracted by the vitality of the formation transformation.

"Maybe!" The old man nodded and sighed: "This place is really amazingly designed, not only has protection, but also a steady stream of food!"

"Alright, let's go!" Jiang Xingchen didn't delay any longer, stood up and walked around with the light source.

The old man quickly caught up and said, "Boy, do you want to think about it, and bring some bats back, these guys are of a higher level than ribs."

Jiang Xingchen thought for a while, shook his head and said, "Forget it, they are used to such an environment, it is better to let them stay here and help us guard that sinkhole, don't forget that the real treasure is in the sinkhole!"

The old man nodded and said: "Indeed, with them guarded, there is no need to worry about the sinkhole being climbed first, hehe, in fact, I don't believe that anyone can enter that terrifying sinkhole!"

Jiang Xingchen smiled, didn't speak again, and strode forward.

The speed of coming out is much faster than going in, and the bats that have been paralyzed by the mandala are already fine, and they are all hanging on the roof of the cave.

Walking out of the bat cave, the old man and Jiang Xingchen looked back, both of them had a sense of relief, in the underground world, there has always been an invisible pressure that binds the body and mind. The moment you walk out of the bat cave, this restraint suddenly disappears.

"Boy, there are tens of thousands of colorful crystals here, do you want to take them away?" The old man asked.

"Don't bring it! Keep it for the bats!" Jiang Xingchen waved his hand, these colorful crystals are the basic energy source of the light source, once they are gone, the environment will change, then his purpose of leaving the bat is likely to be affected.

"If you don't take it, don't take it, there's a level 30 demon beast in front, that must be brought back!" The old man laughed, pointed to the cave that collapsed a few hundred meters away, and said to Xiaolong: "Meat worm, go and open the entrance of the cave!"

"Woo~" Xiaolong screamed twice, jumped up from Jiang Xingchen's arms, and rushed towards the opposite side.

"Bang~" There was a loud bang, the collapsed passage was not opened, Xiaolong screamed, ran back with tears streaming down his face, and a big bag on his head.

The old man was dumbfounded: "Is this Nima still the worm that crashed into the passage?" )
