MTL - Niu Fei Zai Xia - Chapter 51 I don't want a plate.

A 30-year-old NEET is reincarnated into the body of an otaku that choked to death on instant noodles. As he comes to grips with his new life, he realizes that this world is subtly different from Earth. The denizens of this world are far better looking, and this new world also possesses futuristic technology as well as mysterious Yin Yang masters!

Our straight (?) bottom woke up ten years into the future and found himself on the bed of his childhood friend… At the start, the bottom was shocked to his very bones, but he soon quickly accepted this premise and found the whole situation to be rather amusing. Precisely then, the bottom once again went back to his timeline — back to when he and the top were just platonic childhood friends.

Landmines include but are not limited to: Sweet & naive bottom, a president story, logic is dead, slow-progressing romance, the protagonist’s name has too many character strokes, the names are hard to pronounce, too many gay characters…

This is the love story of the 2nd brother of the Dragon Family. He is one of the most successful businessman in the capital and one of the Emperor’s favourites – he is the most eligible bachelor in the capital and every lady in town wants to marry him.

The story starts with the female lead, Ju Mu Er, a blind teacher of guzheng, who goes to pay a visit to Long Yue to ask him to build an awning on his popular business street so her friend, a flower seller, will not get wet and fall sick. Long Yue laughs at her (because he loves money and is calculative) and she makes a bet with him that she can allow him to escape from a pesky female suitor without making it obvious.

She successfully wins the bet and from then on, Long Yue constantly makes her life a trouble (since she costs him so much money)…. not realizing he is slowly falling for her.

Later, he discovered: The swordsman who picked up his broken hatchet became the peerless generation of swordsman; the scholar who often listened to him to chant became the ancestor of Buddhism; the girl who came to learn to play the guqin with him became the supreme demon clan. … Sun Hao sat on the throne of Heavenly Emperor, with a shocked expression on his face: Am I a Dao Ancestor? I take the heaven and the earth as the disc and all beings as my sons, and create a shocking situation? I do not know how?
