Master Who Teaches Secrets from Other Worlds

Time travel means new life. I thought this was my new life, but I didn't expect that this was just the beginning of bad news. If within a year, he cannot promote the peerless skills in the system and the promotion points reach 100 points, then Jiang Xiaoyu can only face death. "Hey, buddy, I see you have amazing bones and amazing aptitudes. I have a legendary and unique Sunflower Book of Kung Fu. Are you willing to learn it? How much does it cost? No, no, no, it's free!" "Don't like it? I also have the Xuanyuan Sword Art, the Immortal Art, the Tao Te Ching, the Yi Jing..." In the eyes of the world, he is omniscient and omnipotent, has friends all over the world, and has disciples all over the world. In fact, he only has one wish, "I want to go home!"
