As an Indigenous Person, I Compete with the Travelers

My name is Li Qingfeng, and I am an "ordinary immortal cultivator" from the Immortal Royal Continent. However, recently I met a Taoist friend. When we first met, I thought I was a good friend. However, he lied to me. Ahhh, from now on, he has been my lifelong enemy! My name is Zongjie, hehe, this is just a nickname. As for my real name, I won't say it. Ahem, long story short. My name is Zong Jie, and I am a time traveler. Now I am a sophomore in college playing games in the dormitory. When I was young and energetic, my friends and I played in row 4, but I cursed, "Trash enemies, they can't even beat me. I've lost contact with you, hahaha, trash, reincarnate, hahaha." That's it. As for time travel, it's really good, hehe. Then, I met a native who had just traveled through time. We got along very well with him at first. However, he just made a joke and actually wanted to kill me. I laughed to death. I have a system. The showdown between the core of the world and the system is not brainless. There are two protagonists. One protagonist has the core of the world and can use himself as the universe. It depends on how I operate it, and readers can also give me suggestions. The main character is the system. Whatever you read and learn depends on whether the system learns it automatically or not. It may feel a little uncomfortable when you separate it from the previous part, so just skip it. Another thing, there may be multiple time jumps, the protagonist's strength improves very quickly, and the latter may be behind the scenes.
