Anton is a great-grandfather. He is living quite a happy life, despite his advanced age and declining health… until a group of cultivator bandits moves into the area. The nearby guardians of the area, the Order of Ninety-Nine Stars, are unable to track them down as they continue to ravage nearby towns. During one desperate winter Anton is out on a hunt when his family- his entire village- is killed or taken as slaves by the bandits. He lacks the strength to fight them, and he wasn’t even present for their arrival to die with his loved ones. At the pit of his despair, he wonders if he ever had any chance to change things. What could he even do? He cannot even pull his best bow, and his eyesight is failing. If he had been a cultivator… perhaps there might have been a chance, but he was decades- perhaps even most of his life- too late.Participant in the Royal Road Writathon challenge (2022)Notes on cultivation levels:There are five general stages of cultivation, though the fifth is extremely rare.

I intended to gather the heroes I had trained to form a guild once again, but…Hmm… it seems all the heroes have completely lost their minds.”

On her wedding day, she was humiliated; her status as the legitimate wife was instantly changed into that of a concubine.

“wh***! Marrying you is my life’s shame!” These were the hurtful words that came from her childhood sweetheart, now husband.

….

Jiejie, jiejie, thank you for your sacrifice. Jiejie, if you’re kind then go. Meimei will replace you and take good care of your husband, to help you enjoy the blessings that you are unable to enjoy!” these words spat out by her smiling cousin made her whole body feel cold.

….

“You are shameless! There is no need to say anything! From now on, our Shen family will not have you as our daughter! Someone! Throw out this shameless woman!” These were her relatives?

…

Becoming the target of criticisms, and being submerged in a small lake, she realized that all of this was the result of another person’s scheme – but it was already too late!

…

Instead of dying, she went back to the past, back to where both feelings were still alive and were loving towards each other; back to when she was not yet an orphan but the doted on Di daughter of the Shen family.

No matter what, in this life, she would never allow anyone to hurt the people she loved. And those people who harmed her in the previous life, she would make them pay the price!
