A Global Travel Game, and I Am the Only NPC

Billions of human beings around the world travel to other worlds, and when they arrive, all living beings will become players. Fight monsters and upgrade, change your job to become a god, and the exciting adventure begins? But when Xu Chao woke up, he found that his system interface was - [NPC Management Backend]. He can see everyone's level, equipment, and even their inner thoughts. He can issue tasks at will and ask the son of destiny to run for him. He can secretly adjust the explosion rate, making the magic weapons valuable but not marketable. With just one thought, he can turn the favorability of the arrogant and domineering top guild leader into hatred, causing him to be attacked by monsters when he goes out! Player A: "Isn't the NPC in this game too intelligent? Are you even counter-offering?" Player B: "Boss, where is the mysterious NPC who posted the hidden mission?" Player C: "Report! I seem to have encountered a BUG... Why am I the only one who can receive the cheating task of 'turning in the highest equipment in the server'?!" Xu Chao mingled among the crowd, hiding his merit and fame. Don't ask me what the hidden mission is, I am the mission itself. Don't ask me to increase your favorability, my mood is the answer to the version.
