Variety Comic: My Life Is Surrounded by Young Ladies

You are already the King of Martial Arts, why don't you increase your lifespan? How about learning shitty martial arts?

He is a native and has no plot memory, so why are you writing about time travel? Wouldn't it be enough to just write about an indigenous person? The biggest poisonous point

A daily comic, the plot is a bit bland, you can watch it

Rewards have been given, thank you to the author, please don't delete the comments! I beg you guys to find a comprehensive manga about Rei Miko, with a deep sea setting. Ordinary people float on the surface of the sea, while weirdos and psykers are under the surface of the sea. The higher the depth, the higher the weirdness value, the stronger the ability. I remember that the depth reaches **, which seems to be the lightless realm. Please, thank you, boss, this is very important to me. The other one is about the male protagonist traveling through the comic book world. He is a literary copycat, but he didn't know at the beginning that there are more anime characters in this world. He wrote a book about a passerby heroine, but was questioned by Shiha Kasumigaoka. He wrote a story about my youthful love, but Yukinoshita Yukino came to her. Zzzzzzzzzzzzzzzzzzzzzz
