In the World of Kexue, Wear Vongola's Vest and Survive

On the day Ito Yuma died, it rained heavily. When he opened his eyes again, he became a "tool man" in the hands of the system. You must constantly shuttle between different bodies to complete tasks issued by the system in order to gain a chance to survive. The system taskbar refreshes very quickly: "Urgent mission: prevent the police in front from being blown to pieces!" "Hidden mission: protect the undercover agent with the gun pointed at his chest!" "Main mission: catch the man in black who gave poison to high school students!" Ito Yuma looked at the body of the junior high school student in front of him and fell into silence. Wait, why should he, a dead man who just "came back to life", want to save the world? ! What's even more outrageous is that there seems to be something wrong with the identity of the vest he is wearing. Today he is the mysterious heir of a certain powerful family, tomorrow he is the heir's most trusted right-hand man, and the day after tomorrow he is even... A five-year-old child? A certain detective boy who always happened to meet him pushed up his glasses: "Brother, are you really just an ordinary junior high school student?" Ito Yuma: Thank you for the invitation. I am in a pile of vests and have just changed my identity, so don't cue. He just wants to live, why does he seem to be causing so much trouble? ? #SYSTEM Do you think I look like someone who can defuse bombs with my bare hands? # # There are too many vests, what should I do if I am almost exhausted? # Things to know before reading: Don't lose your horse during the whole process OOC belongs to me. If you don't like it, you can click on it. Probably just a combination of tutoring, Mingke, and a little bit of black basketball Purpose: Everything is to survive.
