Supreme Emptiness - Chapter 601 Son-in-law of the Demon Emperor

System: You are the only human who meets the binding requirements of this system, please bind with me!

Su Yu: I have money, good looks, power and influence, why should I bind myself to you?

System: You haven’t fallen in love ye-

Su Yu: Aiya! My stomach is hurting all of a sudden!

Su Yu bound himself to a system; his only task is to scatter some IQ to the brainless male protagonists. The soft-headed male protagonist chases after the female protagonist, the male protagonist with some intellect chases after him. He feels that something is not quite right…

Su Yu: System, is there something common between these male protagonists?

System: Yes, they are all male protagonists.

Su Yu: …Suddenly I don’t feel like talking anymore.

Male Protagonist who has been scattered with some IQ: Then don’t talk, just kiss me.

Su Yu: …Suddenly I don’t feel like doing the task anymore.

On a normal boring day, a message appears, inviting him to a Tutorial.

“My unrequited love is over.” Compared to my perfect older brother, I, Ha Giyeon, was endlessly lacking. My first love and my last love—every single one of them were my brother’s friends. What I got in return for pouring all my affection into them were cold, violent words of rejection. Then came the thunderbolt: I wasn’t even their real son. My family, whose love I desperately sought, kicked me out of the house. Even though I scraped by doing hard labor, it didn’t feel like living. Then came the sudden car accident. Right before dying, I regretted everything and begged— That if I ever got to live again, I would never give my love to the family who scorned and discriminated against me, nor to the brothers who tormented me under the pretense of affection. I would live a life that was truly my own. And as if it were a lie, in the winter of my 17th year, Ha Giyeon returned. As Ha Giyeon began to change, so too did the family and the brothers who had once trampled him…

“I believe that if you have a problem, we just need to solve it with firepower.

No talent, weak, and worthless.Until one day, when a fever awoke his previous life's memories and the knowledge of the class from an old game he used to play, Gun Mage.More than just guns, he creates weapons that have never been created in this life and the last.A sword that heats up, turns crimson, and could melt metal.A rune-engraved gun that mages use to amplify their spells.A giant sword that you would only once see in a video game, which makes an explosion every time it hits an enemy.A gun that is powered by mana and shoots out condensed amounts of mana.Airships, steam trains, and boats.Lucen Thornehart isn’t here to play fair. He’s here to redefine warfare, with overwhelming firepower.
