Chapter 578: Seems Like a Big Trap

"Boom!"

Su Sheng threw another punch only to be repelled by a backlash, yet he could feel the force of his punch passing through and even heard the sound of an explosion, as if something inside had been shattered with a single punch.

"What's going on?"

Perplexed, he furrowed his brows, turned around, and took the gun from Liu Gang, pointing it obliquely and pulling the trigger. Bang, the bullet sped out, striking the light curtain and, as expected, reflecting back, hitting the stone wall he had anticipated.

"Instructor, this is too..."

Liu Gang couldn't believe that the object could block bullets and even bounced them back.

"Let's look around, there should be some kind of mechanism."

It reminded him of the fire gate in the Shennong Clan relic, yet it was different. So, taking a bold step, he placed both hands on it. Nothing happened, as if he touched something soft yet firm, which would repel his hands back if he pushed harder, and felt like a soft cushion if he didn't.
