Chapter 821 Choice

If anyone else witnessed this scene, they would definitely exclaim that Yang Yifeng was insane!

Why? Inner Strength is the most powerful and ferocious force in the world, possessing unparalleled destructive power, a force that should not be wielded by humans.

The sole purpose of Inner Strength has always been one thing, that is to destroy! Destroy! And destroy some more!

No matter if it's Dark Energy Gestation, Minor Achievement, Great Accomplishment, or even masters of Dark Energy Perfection, the use of Inner Strength for them has only one purpose, which is to use it for destruction!

But now, Yang Yifeng was doing the unthinkable, using Inner Strength to heal someone! And the part he was healing was none other than the most important, most delicate, and fragile part of the human body—the brain!

If those famous masters of Dark Energy Perfection saw this, they would surely be astounded by Yang Yifeng, and might even harbor thoughts of dissecting him for examination!
