BTTH: From Genius to Invincible - Chapter 316: The Sky Serpent Empire

In the 5th year of Konoha’s founding.The battle between Hashirama Senju and Madara Uchiha at the Valley of the End had come to a close.In order to treat his elder brother’s injuries, Tobirama Senju resurrected a medical ninja from ancient times, hoping that this individual could prevent the injuries from shortening his brother’s lifespan.This medical ninja’s name was Emiya Shigen.

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!
