I Am Lin Langtian in "Martial Arts and World"

I fell asleep in class and when I woke up, I found that I had traveled through time? This is a good thing! From then on, the pig's foot mode is started. As soon as the bastard spirit dissipates, heroes from all over the world bow their heads and bow, and then open a big crystal palace, wow kaka. Wait, that doesn't seem right, why am I a villain? Or a villain who always inspires the protagonist to fight? What's even more tragic is that in the end, he was killed by the protagonist for gaining experience. This script is wrong! For God's sake, play with me! My time travel shouldn't be so miserable! Ps: This is a tragic story that has to be told between a time traveler and the indigenous Mr. Right.
