Shinka no Mi - Chapter 26 – Metastasis Magic

At the end of the story, I found myself in the body of a hidden villain, betraying the heroines. Since I’m not particularly concerned about the end of the world, I’m calmly waiting for the finale… “You’re the only one who truly appreciated my painting of the boa.” “When I make plans to meet you at four, my heart starts racing at three... is this what they call being tamed?” For some reason, the heroines are starting to take an interest in me.

Lu Hanyao is cool and low-key, the most noble man in the capital.

At the age of 25, he fell in love with a girl who was ascetic as he was.

The girl is young and immature, weak and harmless, a delicate flower that will cry when touched.

He took the girl to his side, guarded him day and night, pampered her meticulously, finally waited for the girl to grow up, and prepared to marry someone into the door. The girl who had always been well-behaved and docile unexpectedly ran away before getting married.

After resurrecting his life, the first thing he did was to make the girl a legitimate Mrs. Lu.

…

In her previous life, Su Zhi was a canary raised by Lu Hanyao.

Lu Hanyao gave her the deepest love, the best life, and the most expensive gems, but he did not give her freedom and status.

Reborn at the age of 16, she decided to draw a line with the dog man.

Su Zhi: “Men will only affect my money and career.”

Lu Hanyao: “My surname is Shimingye, and I am super rich.”

Su Zhi:? ? ?

Lu Hanyao: “Welcome to do it.”

The friend reminded Lu Hanyao overtly and secretly, “Su Zhi’s being with you is just for your money.”

With a cigarette between his fingers, Lu Hanyao smiled triumphantly: “There are so many rich people, but she only covets my money, and it’s not because she likes me.”
