Reborn: Revenge of the Concubine's Daughter - Chapter 122 - Six people played Go

To reward Meng Fan for his bravery before his heroic death, the cosmos rewarded him with a ‘system’, sending him back in time to three months ago, alive.

Three Days of Happiness is a novel by Sugaru Miaki, also known as Fafoo. It’s a rewritten version of the story originally posted to 2ch.

The premise of the story revolves around a shop where one can sell away the remaining years of their life, and the consequences of doing so.

“I Say A Little Prayer” is a short related story which was posted along with the novel’s release. It spoils some things about the main story, but nothing major.

I, a HIKKI-NEET, suddenly reincarnated in another world as a prince, and was immediately deemed the weakest ever, with my life already in a pinch after being abandoned as a baby, being stared down by a huge beast!?

However, I could only use one kind of magic. It was close, but I was able to avoid a “dead end” in my first few days of being born using that magic.

Anyways, I just want to live a lazy shut-in life as an adopted noble with my one all-purpose magic, but…?

On modern-day Earth, An Lin seems to have been abandoned by God.
When his father suddenly disappears, An Lin is left with his father’s immense debt, putting his life at risk.
After being forced to a rooftop by his pursuing creditors, An Lin is unexpectedly swept off his feet and brought to the ground safely.

After learning that he was saved by an Immortal, An Lin is gifted, seemingly out of pure generosity, the ‘God Of War System,’ and a pass to a new realm.
Follow An Lin as he experiences a whole new world of legends, meets many new friends, acquires legendary weapons and tools, and starts on his path of becoming a powerful cultivator. There is never a dull time in An Lin’s new life with his ‘great’ new system!
