Lord of Mysteries + Detective Conan + certain characters from other anime

The male protagonist has no romantic partner.

Lin Xiuming is just an identity; in reality, he is Morofushi Hiromitsu, who survived death but lost his memory, and went from being Shinichi Kudo's neighbor to becoming Conan's right-hand man.

Order of appearance of important Conan characters:

Date Wataru (Weapon Master), Chapter 4; Kudo Shinichi (Reader, Deduction Student), Chapter 5; Mouri Ran (Lucky Guy) and Suzuki Sonoko (Praiser), Chapter 11; Professor Agasa (Craftsman), Chapter 20; Amuro Tooru (Nightmare), Chapter 28;

Reborn in the Prince of Tennis world, you begin with the Three-Tama Sharingan. Three-Tama → Mangekyō Sharingan → Eternal Mangekyō Sharingan. On your first day at school, you challenge the Seigaku prodigy, "Your tennis balls are no match for these eyes!" Three-Tama is just the starting point; the path to the Mangekyō, and ultimately the Eternal Mangekyō, has begun! The title of tennis's strongest will be born from these all-seeing Sharingans...

[No romantic pairing, primarily Jujutsu Kaisen, but also includes crossovers with other anime, such as the Detective Conan universe and Heroic Spirit Wars.]

[The main career path and growth path ultimately point to the theme: the ultimate goal is for the Heroic Spirit to summon oneself.]

Having traveled back to the Cursed World, Xia Youjie was still alive at this moment, and the Night Parade of a Hundred Ghosts had not yet begun, but the environment of the Cursed World was really not friendly.

Although he was an ordinary person, he was well-versed in books such as the Romance of the Three Kingdoms, the Records of the Warring States, and the Thirty-Six Stratagems. Xiang Hefeng suddenly had a brilliant idea.

So, when he bumped into Master Xia, Xiang Hefeng calmly smiled.

"Xia Youjie, why don't you consider continuing your sympathetic relationship with Gojo Satoru (in cahoots), working together from the inside and outside (cooperating for mutual benefit), taking down the old oranges, and creating a new world?"

When the summoning failed time and time again, Xiang Hefeng finally understood the principle that it is better to rely on oneself than to rely on others.

Despite being fortunate enough to receive help, he was determined to have his name engraved on the Throne of Heroes.

How can an ordinary person become a Heroic Spirit?

Let's start by changing this corrupt and outdated world of sorcery!
