Chapter 221: Ravenous!

Qin Yu absorbed the dark energy with hunger and thirst. For a moment, the spiritual energy seemed to be suppressed, and there was no movement in his body!

This was the first time Qin Yu felt an endless amount of dark energy!

He even felt that this dark energy couldn't be completely absorbed!

"The ancestor really didn't lie to me," Qin Yu muttered in a low voice.

He didn't know how much time he would have to spend in meditation this time!

Because it was almost impossible to completely absorb this dark energy!

Time passed by minute by minute, and in the blink of an eye, a day and a night had passed.

And Qin Yu's strength had successfully advanced from the third level of the Foundation Establishment Stage to the fourth level!

His body flashed with a golden light, so the golden light stuck to his skin layer by layer, as if it had been absorbed by his skin.

Qin Yu's body became even tougher!
