The Erratum - Chapter 23: Bloodrenders.

When an S-class elite assassin-raised captain of a special ops suicide squad comes home from a high-stakes Africa mission, he finds himself offered something that could potentially set him up for life- a curious assignment that he could use to finally exit his days of war and slaughter.

Then placed into a high-school setting, Lin Yi is tasked by the chairman of a top-tier multi-billion company with bodyguard duty for non-other than his own daughter, a certain little Miss of said high-school.

His enemies, once ranging from drug lords, mafia bosses, political figures, and national leaders, are soon replaced with spoiled kids who happen to have rich papas and mamas, and Lin Yi finds his intense expertise and high-threat skillset misused, and very underwhelmed…

But he does get a harem cast as diverse as his old enemies, so Lin Yi decides that, for the sake of messing around with girls as an invincible entity in a down-leveled environment, leaving his bloody and death-filled war days behind is something he’d definitely want to strive for.

I woke up in this world with a System and a sword. Without hesitation, I chose to complete the princess’ quest with my weapons: Arrogance. Cunning. Pride. I will lead guild Sol Invictus. Denizens of the 7 hells, respect me. Servants of the 11 heavens, know fear. Guild Invictus, know the suffering of training so you can wrest victory from the jaws of those who dare doubt you.

This is a story about a snake named Tycondrius waking up in a fantasy world of swords and sorcery. There is action, violence, unapologetic murder, and arrogant displays of power. There is an emphasis on combat growth as well as psychological growth on more than a few members of Guild Invictus. There is camaraderie and also the inevitable comedic dialogue amongst manly men. There are even elements of romance and Tycon running away from terrifying, powerful women. (Did you know most female snakes eat their partners after mating?)

Xu Shiyan was reborn back to forty years ago, the second day of his wedding.

Shui Lingling’s daughter-in-law has just entered the house, and everything is off to the best start.

Farming, hunting, going to the mountains to dig a big ginseng, life in the 1970s was actually quite good.

I didn’t have much skill in my previous life, and I don’t have any grand wishes in this life. I just want to live a good life with my daughter-in-law and cultivate my daughter into a talent.

The eldest daughter likes to write, so let her take the Chinese department of a key university.

The second daughter likes to sing and dance, and the art school is good.

As for that bastard son, the prodigal son, he didn’t have a chance to stuff it back into his mother’s belly in his previous life, so he just wanted to be born in this life.

But why are some things different?
