MTL - After Transformation, Mine and Her Wild Fantasy - v16 Chapter 43 Change the future

Yeon-woo had a twin brother who disappeared five years ago. One day, a pocket watch left by his brother returned to his possession. Inside, he found a hidden diary in which was recorded “By the time you hear this, I guess I will be already dead….”

The alien DNA is the best thing that has ever happened to Ye Shuang because the genetic optimization it offers has made her more beautiful, more formidable, and more brilliant.

But… why doesn’t this unknown alien species have a fixed s*x before adulthood‽ Alternating between both sexes every few days, why‽ For gender equality‽ Thankfully, she still has a chance to save herself. As long as she can settle down with a partner before full genetic assimilation, she’ll be able to carry on with her life as just one specific sex. For the sake of the perfect female body, all the men out there, beware!

But wait, what are all these women up to? Why are you all looking at me like a piece of meat‽ Halt, stop, don’t come any closer… What the hell‽

A man who was once called the world’s strongest agent ended up becoming a teacher after his retirement, to train a new generation of agents. After many years of training his disciples, he was killed at the age of 60 by a secret organization’s ruse and was reincarnated in another world with his memories intact. Though he was surprised by the existence of magic and the strange species in that world, he quickly adapted to his condition as a newborn and took advantage of it. He acquired special magic and gained a massive amount of strength thanks to his rigorous discipline, in order to reach his goal: Resume his career as a teacher which he left halfway through in his previous life. This is the story of a man, who, based on the memories and the experiences of his previous life, became a teacher who travels through the world with his students.

Over a million years ago, the first human contracted with the first Spirit. Ever since then, Spirit use has become commonplace. Humans used Spirits to carry items and start fires. Eventually, even start wars. Thousands upon thousands of years past and one day, one human did the impossible. He transcended his mortality and ascended to the realm above.
