Re:Zero Kara Hajimeru Isekai Seikatsu - Chapter 24Arc 8, - “To Walk in the Light”

Spend life energy to infuse martial arts, and you can perform unlimited deductions.

Shen Yi’s mortal body only has a lifespan of less than a hundred years. Fortunately, he can gain his remaining lifespan by killing demons.

In the troubled times where evil spirits are everywhere, the long sword is revealed, causing the liver and gallbladder of these creatures who have lived for thousands of years to burst!

From [Eagle Claw Technique] to [Eight Desolations Splitting Heavenly Hands], from [Demon Subduing Fist] to [Golden Body Prison Suppressing Dharma Appearance]!

Shen Yi occasionally ponders, how come this lifespan is getting longer with more use?

He put the sword into its sheath, raised his eyes to the sky, and heard that there was a Jade Palace above the clouds. It was filled with thousands of saints, each of whom had experienced endless years.

This time I came to heaven just to borrow a million years from the immortals to prove my path to immortality.

Xia Ming, a university student who just graduated, accidentally got hold of a system. Xia Ming became powerful! Medical skills? OK, I don’t have the skills. But on the following day, even the highly skilled doctors couldn’t be compared to him.

Force? OK, I’m not your match today but on the following day, even the Great Master would have to concede defeat.

Basketball? OK, I’m a fusion of the world, the strongest basketball star, would I be afraid of you?

Wife, that is even better. I have a beautiful President Lin, and a Missy who is like a rose. Each of them is beautiful, how are you going to compare to me? … … You guys spent a hard time learning skills, acting but I am different.

I have an Almighty System, what skills do I not have? As long as I’m willing, even the celestial beings cannot stop me. With Xia Ming’s words: “As long as the system is in my hands, the whole world is under my control.” I am Xia Ming, I speak for myself.
