So that's how it is!
Lin Feng watched as this scene unfolded, something very familiar to him. Isn't that the Hidden World on the other side? He hadn't anticipated these people using such a technique to open this, to unlock the portal to the Hidden World. As long as the power is sufficient, any kind of power can do. He had once thought this might be a loophole of the Hidden World, but hadn't paid much attention to it. Unexpectedly, these people in black found it.
Now Lin Feng was even more curious about the person in black. He sensed some strange occurrence on the man after he threw the grenade, yet it wasn't a change associated with Gang Qi. He couldn't analyze what exactly it was. But now, being here, he wanted to see what this person in black intended to do.
"Get in quickly."
