I, the System Administrator, Grab the Protagonist Excalibur at the Beginning

I, Lin Xiaoyu, am the gold medal executive of the System Management Bureau. When others travel through time, I issue the system; when others cheat, I set the rules. He was supposed to sit quietly behind the scenes, but he received an urgent mission - to save the fantasy world that was destroyed by the original protagonist. The time traveler Xiao Chen relied on the system to seize the nine world-suppressing divine swords. After becoming an immortal, he swept away the origin of the world, causing the world to collapse and all life to be destroyed. God begged me on my knees, and the bureau gave the order. I traveled directly in reverse direction and returned to the moment when the protagonist just landed. You will be given a world-defining sword at the beginning, along with a complete world script, omniscience and omnipotence, and official support. My mission: to play the ultimate villain, cut off opportunities, snatch the sword, and crush the protagonist! Does he want to counterattack? I cut him off. Does he want to cheat? I blocked him. Does he want to become an immortal? I pressed him into the mud and rubbed him. From today on, the opportunities in this world are mine, the treasures are mine, and I have the final say on the protagonist's life! The boss behind the scenes reduces dimensionality and attacks, specializing in dealing with all kinds of chosen ones!
