Two Worlds and Different Tracks

My college life was very divided. During the day, I sorted ancient books in the Ivy League University library to prepare for the final exam. At three o'clock in the morning, "forbidden knowledge" was sold on the black market in the floating city of another world, and the price was equal to its weight in gold. On the Earth side, the deacon of the Pendulum Society warned me: "Leaker, put away your abilities and don't destroy the stasis balance." On the other side of the world, the general of the United Front recruited me: "Join us and we will give you half of the power to rule the seventh area." I declined. Because my schedule is very full: Monday: Help roommates chase the goddess (using otherworld psychology techniques) Wednesday: Cracking the campus space-time anomaly (collecting source material crystals by the way) Friday: Participate in the alien auction and bid for a "pen of truth" that will give me perfect marks on my final exam. I thought I could maintain this "low-key" dual-world life. Until two things happen at the same time: 1. My history professor mistook the actual date of the "Great Rip" in class - the one recorded in my parents' notes was correct. 2. In the abyss of another world, the sealed ancient god whispered my Chinese name. It turns out that my time travel was not an accident. But... A God-killing plan that spans two worlds.
