Urban magic doctor

After thinking about it, Chen Yang had no clue and flew downwards, looking for the remaining energy fluctuations and clues that the thunder wind might leave behind.

While searching, he asked Ge Yinxiang: "Captain, apart from the square, is there any other place in the back mountain that is worth noting?"

"The back mountain is of no great use. I'm also curious. What do they want to do when they go to the back mountain?"

Ge Yinxiang thought for a moment and said: "However, there is a natural cave in the back mountain, which is thousands of meters deep underground. The caves inside are criss-crossed, like a maze, and it is huge. However, there is nothing worth exploring there. Lei Feng should will not go."

This was the only clue. Chen Yang did not give up and said: "Where is the entrance of the cave? Let's go and see."

Although the back mountain has been razed to the ground, it is a very simple matter for Ge Yinxiang to determine the location.

He blasted away the huge piles of rubble on the ground and quickly found a small cave entrance. Because the rocks collapsed and the passage was buried, it was only half a person high and looked like an animal cave.

If Ge Yinxiang hadn't said it, Chen Yang would never have imagined that there were thousands of meters deep and a labyrinth of caves below.

"I actually entered the cave."

As soon as he found the cave, Ge Yinxiang sensed the faint breath of thunder and lightning. There was no doubt that the thunder wind must have entered from here.

"I'm afraid there's something unexpected down here."

A gleam flashed in Chen Yang's eyes, and he immediately opened up the collapsed passage, taking the lead and galloping down.

The first few hundred meters were just a passage sloping toward the ground. It became wider as it went inside, and finally the passage reached a width of more than ten meters.

Chen Yang observed it and found that the strange rocks in the passage were naturally formed.

After a few hundred meters, continuing forward, there are criss-crossing passages, which look like they were built by man, but there is no trace of excavation.

It has to be said that due to the creation of heaven and earth, this intricate underground cave may be tens of thousands of meters wide, forming such a complex maze. God's methods are not unreasonable.

What's even more frightening is that Chen Yang discovered that these caves actually coincided with the formation method. It was by no means an easy task to find people here.

If you don't understand the formation, ordinary cultivators will probably get lost here.

Of course, it is impossible for this underground cave to block people. The cultivator can dig directly upward to escape the trap.

Lei Feng was full of confidence and did not cover up his whereabouts. He left energy along the way, but it was convenient for Chen Yang and Chen Yang to just follow the traces.

Judging from the remaining energy of Lei Feng, he was not aimless, but had a precise route, moving forward without repetition or detours.

Obviously, his target is under this hole.

"Helmsman, have you ever fully explored this cave?"

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

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

Chen Yang's eyes lit up and he nodded: "It seems that there must be some secret hidden under this cave, maybe it has something to do with the demon clan."

"Is it related to the Monster Clan?" Ge Yinxiang said with a thoughtful look on his face: "But there has never been a Monster Clan in this area. Even the Monster Clan in the Leiling Mountains migrated here later and gradually grew and grew. Moreover, according to our investigation here, there have never been traces of demons here for at least tens of thousands of years."

Chen Yang said: "So tens of thousands of years ago, when the monster invasion war launched by splitting the mountains, could it have occupied this area and left something underground?"

Ge Yinxiang said: "Although Gui Yuanzhou was also a war zone during that war, there were no other resources except for a star source vein. And this star source vein, compared with the Dangge Mountains and many other places, There are quite a few differences, so logically speaking, the demon clan shouldn’t choose this place as its base.”

"That 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 deep underground to find out."

The two of them stopped talking, thinking about each other, and moved forward quickly.

Unknowingly, the two of them went seven or eight kilometers deep into the ground before they reached the end.

This distance is greater than what Ge Yinxiang said before.

Moreover, Chen Yang speculated that this complex underground cave might be more than 10,000 meters deep.

He stopped, glanced at the shrunken dragon fish behind him, and said to Ge Yinxiang: "Master, when we get here, the dragon fish is far away from the formation, and its power has been weakened. If we continue to move forward, we will be thousands of miles away from the dragon fish Guishui formation. Meters away, the dragon fish will disappear completely. If we encounter thunder and wind at that time, the two of us will be in trouble."

"What should we do?" Ge Yinxiang looked embarrassed, thought for a moment, and said, "Why don't we wait here and wait. As long as Lei Feng finishes his work, he will definitely return. When the time comes, we will take him down."

"No." Chen Yang shook his head and rejected the proposal, saying: "If we catch Lei Feng, we may not be able to know the truth. Moreover, what happens below may be detrimental to us, so we must stop it."

After pondering for a while, Chen Yang handed the formation flag to Ge Yinxiang and said: "Master, you stay here, I will go down to find out. If I encounter Lei Feng, I will lead him here. You hide Get up, control the dragon fish when the time comes, and take him down."

Ge Yinxiang frowned and said, "Will you be in danger if you are alone?"

Chen Yang had already stepped into the downward cave and turned around and said, "Even if I can't defeat Lei Feng, it won't be that easy for him to catch me."

Thinking of Chen Yang's mysterious mirror image, Ge Yinxiang felt a little relieved and said: "You should act carefully. If something goes wrong, you must retreat as soon as possible without taking any risks."

"rest assured."

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

Ge Yinxiang hid in the intersecting forks of the cave, clenched the formation flag in his hand, and was ready to control the dragon fish to take action at any time.

But for some reason, he always felt uneasy and felt that Chen Yang's trip would not go smoothly.

"Dongfang Xuan is proficient in formations, alchemy, and understands various miscellaneous subjects such as astronomy and geography. He will probably not be in any danger. Moreover, his mirror image, Lei Feng, should not be able to catch up."

Ge Yinxiang comforted himself.

…

At the same time, Chen Yang quickly penetrated ten thousand meters underground. Fortunately, he did not bring the dragon fish down. Otherwise, the dragon fish would be useless and it would be useless against Lei Feng.

He continued to fly underground, and gradually he discovered that the crisscrossing cave passages around him were different from the previous ones.

What used to be was formed naturally, but what we see now has traces of artificial excavation.

As we continue to go deeper, the cave passage has become completely artificial. The walls are smooth, the passage has edges and corners, and it is made with great care.

"What is hidden underground?"

Chen Yang was wary, always feeling that there would be unexpected gains in this underground place.
