"What do you want to do?"

The Black Tiger King also stood up after he got up. Seeing that he was about to walk in, he couldn't help feeling a little nervous.

"There is a lot of space underground, don't you plan to go and take a look? There may be many powerful beings like these in there!" Lei Yan glanced at the Black Tiger King.

His eyes and thoughts followed the wind and penetrated into the ruins of the building. Soon, a passage appeared in his mind, and he led the Black Tiger King towards that passage.

With him like this, the Black Tiger King could only shrink his body to about ten feet in size and follow him.

On the way, the Black Tiger King looked at Lei Yan and said, "Why don't you use your Secret Art to end the battle much earlier?"

"They are very good enemies and can train a person's combat effectiveness." Lei Yan smiled suddenly and continued, "Come here, firstly, to increase your knowledge, and secondly,

I want to increase my combat effectiveness."

The Black Tiger King nodded and did not ask any more questions. He wanted to train himself to increase his strength. It was normal and he wanted to do it himself.

Going down, the passage is winding and very large. Judging from the current traces alone, there will be a door blocking every few feet. There are also gates on both sides of the passage.

There are rooms one after another, and there are still some remaining fences. It can be seen that this was indeed used to imprison those giant beasts. However, the cages here are not very

It's not big enough to hold a giant beast several feet high.

The further down they go, the more shocked they are. The space below is far beyond what they thought.

Just like a funnel, the further down you go, the larger the space is and the fewer channels there are. On the contrary, the larger the empty spaces are.
