After Marrying a Vegetative Princess, I Went Crazy With Joy! - Chapter 120:

Long ago, there were people who stood upon the earth with their heads held high. They never bowed to anyone because of their indomitable spirit. They were capable of controlling wind and lightning, and conquering dragons and serpents. They seemed strong enough to split the earth and shatter the stars with their fists. They traveled throughout the land and called themselves Magi. Eventually, one of them would become a Supreme Magus! These men are the ancestors of human beings. Their blood is what we all share today.

Qing Long is the former strongest man in the world. He traveled through space and time and was reborn as Ji Hao in the Fire Crow Clan of the Southern Wasteland. It’s a complicated world. Forces from both inside and outside of the clan want this young and talented boy to die. Under great pressure, Ji Hao makes a deal with a mysterious man, who resides in his spiritual space, never showing his real face. He gains two drops of blood from a dragon and phoenix. Afterwards, Ji Hao becomes increasingly more powerful.

Tang Long was brought to the Immortal Cultivation World by an immortal who noticed his affinity to wood and cultivation.
Relying on his amazing talent, became one of the five emperors of that world.
He failed his Heavenly Tribulation and had his soul scattered into pieces but one part found its way to Qin Haodong on Earth.
With his excellent medical skills, he became a divine doctor of traditional Chinese medicine and encountered the baby girl he made before going into the Cultivation World, whose mother was as pretty as a fairy. The little girl even asked him to find more lovers. What a cute girl…

“I’ve been possessed into the controversial makjang drama ‘Gwangin’ (The Lunatic). Of all roles, I’m the omega secretary to an alpha with omega-phobia. It’s hard enough hiding my identity, but I’m also in charge of all sorts of annoying tasks: managing the protagonist’s diet, wardrobe, and house; coaxing and soothing the beta he loves. My goal is to survive until the ending where the protagonist meets the strange beta who thinks even his obsession is love, leading to a happy ending… I think I smell an omega somewhere.’ ‘That’s… impossible.’ If I speak carelessly, I die. If I mess up my work, I die. If I run away, I die. And if the fact that I’m an omega is revealed… I really die. ‘Right. It shouldn’t be possible, but that’s why I feel so f*cking awful, Secretary Kim.’ Will I be able to make it back alive…?”

Humanity has been gradually transported to the Abyss by a bored god to compete against other races and monsters.The problem is… humanity failed. In a last desperate push the strongest survivors chose a comrade to travel as far as possible back in time.
