Investing is risky, and Zheng Yichen has just begun by fixing a depot in this world for 1 merit point. If the authorized person in this world dies in an accident, it means no one would know about the Proxy Agent's or the Dusk mercenary's depot in this place.
Moreover, the authorized person in this world doesn't have any extra authorization rights, and if such a situation occurs, it would mean the investment was in vain.
1 merit point might not seem like a lot, but acquiring merit points is not easy, and there are always lots of places where merit points are consumed continuously.
If such a situation arises, there is still a way to resolve it, which is to come back directly and look for a new investee, but that also costs money. It's not just cash that is needed, but merit points too. When there's a mission, one could say it's a business trip covered by public funds, with no need to spend anything.
