He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory?

“It was an era taken over by a single online game, the “”Second World.””

The “”Second World”” offered a vast amount of classes and skills...

Micheal, our protagonist, reincarnated back into this era and realized he had a few bugged passive skills that would put him as one of the best.

[Passive skill: Damage Reduction: When you receive damage from an enemy, the damage will be reduced accordingly to the reduction percentage. Skill lasts for 10 seconds and takes 10 seconds to cooldown.]

[Passive skill: Damage Reflect: When you receive damage, the damage will be reflected accordingly to the reflection percentage.]

[Passive skill: Damage Multiplier: When you deal damage to an enemy, the damage you dealt will be multiplied.]

[Passive skill: Sword Attack Nullifier: When you attack an enemy with a sword, the enemy will kneel in front of you and catch your blade with their bare hands.]

[Passive skill: Priest: When you suffer from damage, automatically heals yourself.]

[Passive skill…]

[Passive skill…]

.........

After reading through all his passive skills, he suddenly realized how invincible he as.

Even though he didn’t possessed a single active skill, he could still triumph over everyone else with his passive skills.

One day, when the “”Second World”” mysteriously merged with the real world, monsters and divine beings began to invade Earth…

That was when Micheal realized that his passive skills have also given him the power to kill these divine beings…”

Xia Ming, a university student who just graduated, accidentally got hold of a system. Xia Ming became powerful! Medical skills? OK, I don’t have the skills. But on the following day, even the highly skilled doctors couldn’t be compared to him.

Force? OK, I’m not your match today but on the following day, even the Great Master would have to concede defeat.

Basketball? OK, I’m a fusion of the world, the strongest basketball star, would I be afraid of you?

Wife, that is even better. I have a beautiful President Lin, and a Missy who is like a rose. Each of them is beautiful, how are you going to compare to me? … … You guys spent a hard time learning skills, acting but I am different.

I have an Almighty System, what skills do I not have? As long as I’m willing, even the celestial beings cannot stop me. With Xia Ming’s words: “As long as the system is in my hands, the whole world is under my control.” I am Xia Ming, I speak for myself.
