MTL - Super Card System - Chapter 1 Master brother

In a world torn apart by rifts that release dangerous monsters, Espers—humans imbued with powerful abilities—serve as humanity's last line of defense. But the power of an Esper comes with a price. Overuse of their abilities leads to dangerous corruption, a force that can destroy them from the inside out. This is where Guides come in: individuals with the unique ability to calm the corruption within Espers and restore their balance.Rowan Mercer, an S-class Guide, is one of the best in his field, capable of stabilizing even the most dangerous Espers. He has worked quietly behind the scenes, helping those in need, but his life takes a dramatic turn when he is called to work with Lucian Vaughn, an S-class Esper whose immense power and unstable corruption levels make him a dangerous threat to himself and others.Lucian, a tall, stoic, and enigmatic figure, has long fought against the growing corruption within him. At first, his relationship with Rowan is purely professional—Rowan as his Guide, helping him to stay in control. However, as their interactions grow more frequent, their bond deepens in ways neither expected. What started as a simple duty soon turns into a complex relationship where power, trust, and vulnerability collide.As the world around them faces escalating threats from rifts, Rowan and Lucian must navigate not only their personal challenges but also the dangerous world of Espers and Guides. Their bond will be tested as they fight together against the corrupting forces that threaten them both.In Corrupted Bonds, survival isn’t just about battling monsters from the rifts—it's about fighting the darkness within themselves and finding a way to stay connected in a world that’s constantly pulling them apart.

Xia Zhijun got the title ‘study god’ after scoring first place in the whole city. He’s the model of a good student in a teacher’s eyes: good grades, good manners, and quiet. When he wasn’t smiling, his entire body emits a cold abstinence aura. The girls only have the guts to look from afar and not get close.
Later, it was rumored throughout the entire school that even the study god would fight and hit on girls. Whoever dared to provoke his girl, he would teach you how to be a person at every minute. The night of the graduation ceremony someone saw him blocking Gu Siyi in the corner. He didn’t stop kissing even when she cried. He bit her lips and said in a raspy voice, “I’m going crazy…”
During college finals, Gu Siyi almost bursted out crying, “I’m such a failure. I won’t be able to find a good job in the future…And if I can’t find a good job, I can’t provide for myself…”
Xia Zhijun played with her pink earlobe and remarked, “I’ll take care of you.”
After they graduated, Xia Zhijun created a research company and Gu Siyi became the boss’s wife.
The commercial rocket, “Star of Siyi” was successfully launched. So everyone knew that the new technology superstar, Xia Zhijun has a wife who he spoils a lot.
