Sports Students Crack the Apocalypse

My name is Lei Yi, a sports student who is about to graduate. Alien beasts are coming, and the end is coming. Others have to follow the instructions when implanting the "Origin Seed". It is implanted in the spine and connected to the nerves of the brain, transforming into a mecha warrior. But I can't understand that thing. Looking at the crystal in my hand that is said to be life-saving, I thought it was similar to protein powder, right? So, relying on the intuition of an athletic student, I inserted it into my most confident biceps. Now, the instructor watched me blow away the training alloy target with one punch and fell into deep thought. The entire institute's outlook is being shattered.
