I'm The King of Business & Technology in the Modern World - Chapter 124: Playful Tease

There are three realms in the multi verse; The Cosmic, the Mortal and the Nether realm.

Hal grew up in the mortal realm with no idea whatsoever of who his parents were.

His love for relics, adventure and the occasional danger would aid him in finding a genie's lamp.

Rubbing a genie's lamp should grant three wishes, but Hal is struck by lightening instead and eventually arrives in the Cosmic realm with a large book in his mind space titled; The Primordial Cosmic Grimiore, that apparently holds all knowledge for a perpetual reign.

And so Hal's journey begins in a little city called Salmon city, in the body of a 17 year old boy also named Hal but was sold into slavery by his own father.

Hal finds out who his mother (prior to reincarnation) whose bloodline now flows unmixed in his new body is....

Join Hal as he battles mortals, Dragons, phoenixes, Gods and many more together with his harem of Beauties for the complete subjugation of the three realms.

Xu He had been his sister’s control group since he was a child. His elder sister was fair, juicy and good at giving birth. She was the heart of the Xu family, a flower in the village, and the talented people who wanted to marry her lined up from the village to the back of the mountain.

The little brother was only good at cooking, and he was busy from the stove to the field all day long, and no one paid attention to his disheveled face. People in the village talked after dinner, how the same parents had two very different children. With his sister as a comparison, it must be more difficult for He ge’er to marry. 

However, there were many young men looking for Xu He, but these people who got close to him were all to find out about his sister. Xu He had been used to it for many years, but recently, even Zhang Fangyuan, who was not doing business in the village, wanted to get something from him.

After inquiring, he tried to hide, but he was stuck on the way home, but the man said: “He ge’er, your cooking is delicious, and it will be even better if you are my fulang.”
