Re:Zero Kara Hajimeru Isekai Seikatsu - Chapter 2Arc 8, - “Grudges”

King Grey has unrivaled strength, wealth, and prestige in a world governed by martial ability. However, solitude lingers closely behind those with great power. Beneath the glamorous exterior of a powerful king lurks the shell of man, devoid of purpose and will. 

Reincarnated into a new world filled with magic and monsters, the king has a second chance to relive his life. Correcting the mistakes of his past will not be his only challenge, however. Underneath the peace and prosperity of the new world is an undercurrent threatening to destroy everything he has worked for, questioning his role and reason for being born again. 

It has been more than ten years since he was transported to another world. The protagonist Deris Fahrenheit, who has became a magician with special circumstances, was freely enjoying his life in this world. However, a girl appeared before him and asked him to make her his disciple. That girl seems to be a transported person――

It’s a story of him who becomes the girl’s teacher and trains her to achieve her revenge (?) in otherworld.

Ji Qingqing was at the end of her rope. When she was on the brink of wretched poverty, she received a system. The system told her; Lu Lixing came from a family that was rolling in money, but he was coming to the end of his allotted lifespan. If she married him, she would gain his enormous inheritance.

Lu Lixing was seriously ill. Just as he was about to die, he gained a system. The system told him: Ji Qingqing was young and beautiful. She was rich in vitality. If he married her, he could continue living.

Ji Qingqing happily came to Lu Lixing’s sickbed.

And then, Lu Lixing woke up.

***

Lu Lixing’s friends discovered that after Lu Lixing woke up, not only did this person that had always kept his distance from women gotten married, he spent every day being super clingy towards his wife.

Young Lu, can you be a little less embarrassing and act your age? Will you die if you take one step away from your wife?

Lu Lixing clutched his chest. His little heart had almost stopped beating because Ji Qingqing had left him for half an hour. He weakly waved his hand. He couldn’t be separated from her, not for the rest of his life. She was his life.

Transmigrating from the Apocalypse to a technologically developed, peaceful world, Qiu Yu’s killing skills cultivated through hundreds of life-and-death situations suddenly lost their use, and even his body turned into a weak, squeamish…

Qiu Yu’s world views shattered into pieces: What the heck is an Omega?!

Qiu Yu, who knows nothing but fighting, eventually decided to become an anchor for a full-dive game—not only could he use his battle techniques to make a living, but he also didn’t have to brave leaving the house and meeting people—it was the perfect job.

However, in his first-ever broadcast, he shot an arrow straight through the heart of the e-sport circle’s verified no.1 god of war.

Mu Feibai touched the place above his heart, the corner of his mouth hooking up: Interesting… Come play professionally.

Qiu Yu rejected him: social anxiety, not going, see ya.

…And then he was sold off by his live-streaming platform to play for a professional team.

Qiu Yu: This was different from my plan!

Mu Feibai: You shot an arrow straight into my heart… baby, you still want to run?
