“Kill Hamyuts Meseta”

A story about a world where all dead people become “Books” and are housed in a Library. The boy named Colio Tonies had his memories taken and a bomb transplanted in his chest. His life’s purpose is killing the world’s strongest Armed Librarian, Hamyuts Meseta. But, one day he gets his hands on the “Book” of a beautiful princess and falls in love at first sight. Furthermore, that love will cause Colio to get involved in a grand scale battle…

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.
