Strategic-level fantasy syndrome patient

Ji Tianqi, who fantasized about crossing into an otherworldly realm, was diagnosed as a fantasy syndrome patient. However, his extraordinary encounter in the otherworldly realm came true!!!
In his first extraordinary encounter, he obtained a martial arts secret book that no one but he could master.
Therefore, the team responsible for researching/treating him provided him with a prop—a chessboard!
His second extraordinary encounter involved solving the Zhenlong Chess and gaining the empowerment transmission from a master, which granted him a century-old skill in minutes.
From then on, the team responsible for researching/treating him became a team dedicated to assisting him.
His team created an inn setting for him, where he experienced his fourth extraordinary encounter—the Orchid Acupoint Skill. With this martial art, he immobilized a criminal possessing the superpower of Instantaneous Movement.
His team submitted a request report to their superiors—our hero needs to rent a temple, a temple with a Scripture Pavilion.
After the superiors rejected it, they issued an important directive.
"Think bigger, construct a real ancient city for him! An ancient city that includes all the headquarters of the various sects from his otherworldly fantasies!"
