I Was Locked in a Dark Room at the Beginning, and I Summoned Thunder from Behind

Qi Tian is a son of the Xu family. He has been living abroad for fourteen years. He was brought home by his father Xu Donghai, but he was scorned and abused. He was even slandered by his adopted son Xu Siwen. Finally, one time he ranked first in the school. He was accused by Xu Siwen of cheating and plagiarism, beaten by his father Xu Donghai, and starved in a small dark room by his mother Qin Ruping for three days and three nights. After eight hundred years of traveling to other worlds to cultivate immortality, Qi Tian vowed not to be the slave of the Xu family anymore. He first used force to frighten everyone in the Xu family and demanded 5 million from Xu Donghai. Then he went back to school to ask the teacher who accused him of plagiarism to apologize, and slapped the Xu family's marriage partner Liu Ruyan and others in the face.
