After thinking about it, Chen Yang was clueless, flying towards the bottom, looking for residual energy fluctuations and possible clues left by thunder wind.

While searching, he asked Ge Yinxiang: "Lord Master, is there any place other than that square in Houshan that is worth noting?"

"Houshan is useless, and I'm also surprised, what are they going to do when they get to Houshan?"

Ge Yinxiang pondered for a moment and groaned: "However, Houshan has a natural cave that is thousands of meters deep. The caves are criss-crossed like a labyrinth. They are huge. However, there is no value worth exploring. Thunder should be will not go."

This is the only clue, Chen Yang did not give up, saying: "Where is the hole, let's go and see."

Although Houshan has been razed to the ground, it is a simple matter for Ge Yinxiang to determine the position.

He blasted the ground to pile up megalithic ruins, and quickly found a small hole, because the rock collapsed and the passage was buried. It was only half a person tall and looked like an animal cave.

If it wasn't for Ge Yinxiang, Chen Yang would never have thought of it, it would be thousands of meters deep, and there would be labyrinths.

"Suddenly entered the cave."

As soon as he found the cave, Ge Yinxiang sensed a weak thunderbolt. No doubt, Lei Feng must have entered from here.

"Below, I'm afraid there is something we didn't expect."

Chen Yang's eyes flashed, and he immediately opened up a collapsed channel, and he sped away towards the bottom.

The first few hundred meters was just a passage inclined to the ground, and the wider it became, the more the passage reached ten meters wide.

Chen Yang observed that the channel weird magpie was naturally formed.

A few hundred meters later, proceeding forward, there are criss-crossed channels that look like they were built artificially, but there are no traces of excavations.

I have to say that the heavens and the earth are intricate, and this intricate hole is tens of thousands of meters wide, forming such a complicated maze. The method of God is not mysterious.

What's more frightening is that Chen Yang found these burrows in secret, and it was not easy to find someone here.

If you do n’t know the matrix method, practitioners here are likely to get lost.

Of course, it is impossible for the burrow to block people. The repairer can dig out directly to get out of trouble.

Lei Feng was full of confidence and did not cover his whereabouts, leaving energy along the way, but it was convenient for Chen Yang and the two, just follow the track.

Judging from the energy left by the thunder wind, he is not aimless, but has an accurate route, all the way forward, no repetition, no detour.

Obviously, his goal is just below this cave.

"Master, this burrow, have you fully explored it?"

As Chen Yang moved forward, he turned to look at Ge Yinxiang and asked.

Ge Yinxiang shook his head: "This burrow is very complicated and there are no traces of human survival, so we have not explored it carefully."

Chen Yang's eyes brightened, and he nodded: "It seems that there must be some secret hidden under this burrow, maybe it has something to do with the demons."

"Related to the demons?" Ge Yinxiang showed his thoughts and said, "But in this area, no demons have ever appeared. Even the demons of the Lei Ling Mountains have migrated and gradually developed. And, according to our investigations here, at least tens of thousands of years, there have never been traces of demons here. "

Chen Yang said: "Well, tens of thousands of years ago, when the war of demon aggression launched against the mountain range, did it occupy this area and leave something under the ground?"

Ge Yinxiang said, "Although Guiyuanzhou was also a war zone in that battle, there was no other resource except a star source. This star source is compared with the Acura Mountains and many other places. It ’s a lot worse. It stands to reason that the demon tribe should not choose this place as a stronghold. "

"This statement makes sense." Chen Yang nodded and said, "It seems that if you want to solve the mystery, you can only know the truth by going deeper."

They no longer spoke, they both thought about each other and moved forward quickly.

Unconsciously, the two went deeper into the ground for seven or eight kilometers, before they reached the end.

This distance is beyond what Ge Yinxiang said before.

Moreover, Chen Yang speculated that I was afraid that this complex burrow might be more than ten thousand meters deep.

He stopped, glanced at the dragon fish that shrank behind him, and said to Ge Yinxiang: "Heard Lord, here, the dragon fish is far away from the formation, and its power is weakened. If you continue to move forward, you will be far away from the dragon fish guishui array. A few meters away, the arowana will disappear completely. In case of thunderstorm at that time, the two of us will be in trouble. "

"What should we do?" Ge Yinxiang showed his embarrassment and thought for a while, and said, "It's better that we stay here and wait for the rabbit. As long as Thunder wind is done, we will definitely return, and we will take him down at that time."

"No." Chen Yang shook his head to veto the proposal, saying: "Caught thunder, you may not know the truth. Moreover, what happened below is likely to be against us, so we must stop it."

After contemplation, Chen Yang handed the banner in Ge Yinxiang and said, "Lord Master, you stay here, and I will continue to explore. If I encounter a thunderstorm, I will lead him here. You hide Get up, take control of the arowana and take him down. "

Ge Yinxiang frowned: "Are you alone in danger?"

Chen Yang had already stepped into the downward cave and turned back: "Even if I can't beat Thunderwind, but he wants to catch me, it's not so easy."

Thinking of Chen Yang's mysterious mirror image, Ge Yinxiang was a little relieved and said, "If you act carefully, if you don't see the opportunity, you must retreat as soon as possible without risking."

"rest assured."

Chen Yang suddenly accelerated, and the figure disappeared into the cave in an instant.

Ge Yinxiang hid in the staggered fork in the cave, clenched the banner in his hand, and was ready to control the dragon fish's shot at any time.

For some reason, he always felt uneasy, and felt that Chen Yang's trip would not be so smooth. What danger. Moreover, his mirror image, Thunder Wind should not be able to catch up. "

Ge Yinxiang comforted himself.

...

At the same time, Chen Yang quickly reached the bottom ten thousand meters below the ground. Fortunately, he did not bring the arowana down. Otherwise, the arowana would fail and it would be useless to Thunderwind.

He continued to fly underground, and gradually, he found that the surrounding cave tunnels were different from the previous ones.

What used to be formed naturally, but now you see, but there are traces of artificial excavation.

As it continued to deepen, the cave channel has completely become an artificial excavation, the walls are smooth, and the channel has edges and corners.

"What's hidden here underground?"

Chen Yang was vigilant and always felt that there would be unexpected gains here.
