Becoming evil makes you ten times stronger, but becoming a demon gives you hundredfold strength - Chapter 515 - 380: Blood Knife Legacy, Mingxin’s Enlightenment_2

This is the story of a young man who was reincarnated as a dragon with a near-insatiable curiosity. Initially sparked by questioning his own reincarnation, he quickly gets lost in the endless world of magic, using his deep understanding of advanced sciences to learn the laws and properties of a new type of energy known as mana.However, soon enough, the table would flip, and he would begin using that very same energy to expand his knowledge of science, to the point that he would begin questioning his own understanding of the world.Although not his original intention, with the combination of his intelligence, expanding curiosity, and the 'miracles' that occurred to allow for his existence, he quickly found himself climbing the mountain of strength as if it were a small hill before eventually climbing to a point where it seemed as if he himself was the peak itself.Even if.. that was never the case...There is mild gore, and profanity is 'censored' toward the beginning, but not later in the story.

I thought the world was vast, for me to wander, but now, it has only become a cage. For a life unhindered, I wield a single sword to pierce the ninth heavens. People find me displeasing, but there’s nothing they can do. That’s the kind of life I love!“Stop! I paved this path and I planted these trees. If you want to pass through…”“Brother, I come from the Dustfallen sect.”“What? The Dustfallen sect! Piss off!”This pitiful sect was so poor to the point where even bandits did not want to waste time on it. However, how could this sect, these nine measly people, be ordinary? What you see is only what they wish for you to see. What you can’t see is the truth!Mu Yu—a young human boy with the powers of elemental demons—accidentally joins the impoverished Dustfallen sect. The sect that even bandits did not want to waste time on was actually hid great talents, concealing a huge secret! You look down on my sect? Then that’s your ignorance!

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.
