9.9 Memory potion

Shu XinYi raised his hands and used his corrosive ability for the first time almost instinctively, 5 fine nails formed above his palm, the nails had a corrosive fog around them, similar to the arrow. Shu XinYi observed them closely, they didn't look anything speacial but Shu XinYi could feel the immense power they held. Ryuji also raised his palm, and a dark fog vortex formed above his hand, "This is pure corrosion. If I let it roam free, it could potentially destroy half the planet's landforms. But the corrosion on those nail, it won't spread, only affecting the impacted area. Except when used on living beings. You can take your time, and you'll understand how it works."

Shu XinYi was unconsciously about to touch the black vortex when Ryuji closed his palm advising calmly, "XinYi, don't touch it, or you'll end up like those beings."
