Tower Defense: I Will Continue to Develop a Small System to Save the World

Bad news, the host bound three years in advance died. Good news, the former host left a legacy (Fa Xiao) In this case, the responsibility of saving the world falls on the legacy! I lead the host to kill indiscriminately, I am responsible for the quack, and the host is responsible for the killing —— Want to become a genius that attracts much attention? Do you want to fight back against this fucked up life? Want to become the number one tower defense player in the game? Come and bind the system, and the system will take you to the top! [Congratulations to the host for binding the three-year college entrance examination and five-year simulation system. Shi Bai: Wait, I didn't agree! [Gift package for newbies has been opened] [Congratulations to the host for obtaining "Extreme Tower Defense Simulation Exam Question × 1"] Shi Bai: No, I said I didn't agree! [Welcome to the "Extreme Tower Defense Simulation World", there are still 23 hours, 59 minutes and 59 seconds before you enter the "City Defense Battle". For the sake of your life, please complete the simulation test questions in time] Shi Bai: You ** forcefully buy and sell! Then... System 525 looked at the host killing everyone and fell into deep thought: Well, it seems that the new host can counterattack without me. Wait, the new host itself is a genius and does not need to counterattack. Oh, no, it seems that I need it again. Looking at the "host" who took off his hat, smiled gently, and stood on the front line of tower defense holding a machete, System 525 silently opened a post on the internal forum to ask: Help! As a savior system, what should I do if the host's personality is split and the world feels like it will be destroyed at any time?
