At the same time, to meet these conditions—having no soul, being shielded by Scorching Sun's protection, and not drowning—there shouldn't be a second person, right?
No, you'd have to add another condition: knowing how to find your way, without getting lost here.
Once the warhead was buried, Wen Yan came out of the water and began to pack his things.
