Chapter 563: The Lion Fights the Rabbit with All Its Strength_1

```

The Ancient Sea, reaching tens of thousands of miles deep, looked like a profound black hole.

To the eyes of mortals, it was truly bottomless.

With a thought, Qin Changqing began to descend.

"The place where the Ancient Demon resides is isolated from heaven and earth. If it can hide inside, I should also be able to exert my full strength after entering,"

Qin Changqing thought.

As long as he could exert his full strength, the Ancient Demon wouldn't be able to stir up any trouble.

As for the strength of this Ancient Demon, it was hard to say.

When Qin Changqing first sealed this place, he was at the second-tier decline celestial being level of power, and the Ancient Demon had not come forth.

But that doesn't necessarily mean the Ancient Demon lacked the strength for Tribulation Passing.

More than two thousand years have passed since then.

The last time the Eastern Sea Tribe went down, they must have brought a significant amount of resources with them.
