Immortal Reborn As City’s King!

He was at the top of the cultivation world and the one thing left was to ascend. The tribulation went against him and his soul came down into the body of a young man in the city, a son-in-law the household treats as worthless. The body and the soul do not sit together properly, and that is the first thing he has to fix. His ex-wife is running something against him at the same time, and a rich family in the city has an interest in the ground under the pharmacy his new family owns. The medicine he knows can do things the city's hospitals cannot. He treats a woman for a disease they had given up on and her family opens its doors to him. The pharmacy comes back off the floor and a doctor the city treats as an authority asks to study under him. What is under the building is a dragon vein. The rich family sends men for it, and he deals with them himself.
