I'll Just Build a Laser Cannon. Why Are You Panicking?

Li Yu inherited the auto repair shop left by his father and started a journey of live streaming to sell goods.

Long Guo knew that all this could no longer be hidden. And after learning all the truth, Yingjiang was scared to death on the spot... This novel and its characters are purely fictitious.
