Harry Potter with Technology System - Chapter 13: Occlumency

Dual cultivation and apocalypse—words that mix like oil and water. There's nothing charming about seducing feral women on the road.

However, when Kaze Lexicon, the emperor of the Immortal Plane, got transmigrated into the past, he refused to give up his debaucherous ways—apocalypse or otherwise.

Armed with the knowledge of the future and an encyclopedia of overpowered cultivation techniques, he immediately set forth to obtain resources and build a lavish settlement to live a comfortable life dual cultivating in the apocalypse.

However, while it's obscenely protected and powerful, he finds himself in another predicament. The cultivators farming humans for their war, and the desperate humans, become enemies far more dangerous than the zombies and monsters that afflict humanity.

Join Kaze as he rebuilds his reputation from a bullied weeb, obtains wealth, builds power, starts a faction, makes lemonade, trains his people, protects his past lovers, conquers settlements, and fights humans, monsters, and cultivators, all for the sake of two obscene goals: enjoying life and building an army of engineers to bring modern technology to the higher planes.

Within the red tent, under the passionate eyes of the man on top, she was forced to make love and three thousand black strands turned to white.

Outside the red tent, her husband laughed and drank with the beauties by his side as they watched…

When the red was torn, pieces of it were carried away by the wind. As she stepped out with difficult steps, the silver hair danced in the wind. Exactly whose heart was the one that was hurt in the end?

“How…how could it be you?” A voice filled with disbelief, he who always believed himself to be cold and unfeeling, fell into the pits of hell, filled with pain and regret for eternity.

For this imperial power, there are countless hidden plots. She hid her capabilities and bided her time, only desiring for a safe haven. In the end, her wish did not come true, and she fell into the hands of someone else as a chess piece.

The tale of a time-traveling woman who gets forced to the point of no return, turning her black hair into white. Should she bow to her fate and submit? Or should she fight back and glow brilliantly?
