Sage in the City: 24-Hour Comeback

Jason's mother is carrying online loans his adopted brother pushed her into. The money from his patent went to Derek, who was a friend of his. His father is dead, and Alyssa, the girl he liked, is with his rival. Jason was a college student when he ended up in the cultivation world. He spent ten thousand years there and reached the rank of Sage before he got back to Earth, where one day had gone by. He goes after the people who had been standing on him. He dismantles the loan operation his mother is tied to, gets the head of the Reed Group out of a bad spot, and helps Zoe, who had been quietly in love with him, get back to where she had been. Other cultivators are hidden on Earth, and he uses the ten thousand years of cultivation on them.
