Getting a Technology System in Modern Day - Chapter 799 Fireworks

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.

Yo, Hi! I’m Frank, I made a deal with a demon to pay me some money for receiving a guest for a few days every week.
I had no idea about what I have done.

On May 16th, Hannibal Lecter, The Silence of the Lambs, came to my home. I can only say that I really can’t stand my guests.

Jiang Jiuqing is the princess of a vanquished nation. No one knows her extreme cleverness hidden under her ordinary skin——she also doesn’t want others to know either. Staying out of things is her manner towards handling affairs, and wanting nothing is the norm in her life. However she has a white moonlight. After not seeing him for many years, he has now completely blackened, causing trouble everywhere——The world’s number one lobbyist, the peerless and magnificent Young Master Ji Yu.

Jiang Jiuqing had always thought that the reason why her white moonlight is a white moonlight is because he has forgotten about her, and will never belong to her. He is her master, and she assists him in lobbying the world. They are just allies, a symbiosis relationship, mutually using each other.

A long, long time later, Ji Yu said——

“This world is frantic and absurd. Malicious people die an ugly death, and the merciless people are sought after. I was never reluctant to leave until I met you.”

There are thousands of people in the world, and thousands of beauties, yet it is only you who can disturb my heart.

Are you ready to fall in love with the smartest and most cold-hearted people in the world?

The calm and cool-headed princess of a vanquished nation x the ruthless and revengeful number one lobbyist.

Male and female leads are both very strong, white cuts black.

“White cuts black” = someone who looks very gentle on the outside, but in fact, is actually very ruthless and two-faced
