What happened on August 2?

Chen Xu pressed the switch beside him, dropped down into the passageway below, and escaped the weapon platform that was being continuously corroded by the Acid Ant Beast's bodily fluids.

He had only run a few steps when he heard a sizzling sound behind him. Turning around, he saw green viscous fluid dripping down from above, quickly corroding a hole in the passageway floor.

"Good thing I ran fast."

He felt relieved for a moment when he suddenly felt a burning sensation on his left forearm. Looking down, he saw several drops of the green viscous fluid on his protective suit, which had already burned several small holes in it.

To not hinder his speed, he hadn't worn the external mechanical arm but donned an S01-provided protective suit made of high-strength material. He had tested it with a handgun. Within three meters, bullets couldn't penetrate it. Its bulletproof capability was exceptionally impressive.

And yet it had been burned through by just a few drops of fluid.
