High Martial: I Become Invincible Starting as the School Beauty's Human Shield

I transmigrated into a high-martial world with a blood-energy rating of just 5, and my entire class laughed at me as a good-for-nothing?

My parents took out a loan from loan sharks to buy me pills. It was my last hope of becoming a martial artist!

Just as I was despairing, the campus beauty suddenly crashed into my arms. “Hey, pretend to be my boyfriend and I'll give you 200,000!”

Just as I thought my luck with women had finally turned around, the god-tier System arrived!

[Ding! The Host faces a fateful choice...]

[Option One: Accept the beauty's request and bind the “God-Tier Enhancement System”!]

[Option Two: Reject her and be a poor person with some pride. The System will disappear on its own...]

Was that even a choice? I agreed on the spot. “Sure, girlfriend!”

[Congratulations, Host, on binding the “God-Tier Enhancement System”! It has one function: slay demonic beasts to directly convert a proportional amount into the Host's own blood-energy value, with no limit and no bottlenecks!]

From then on, while everyone else painstakingly meditated, trained, and took pills to level up, all I had to do was... kill!

[Ding! Successfully killed a first-rank demonic beast, “Black Armor Ant.” Blood-energy value +1!]

[Ding! Blood-energy value +1!]

In a single night, I went from a good-for-nothing with a blood-energy rating of 5 to a second-grade martial artist!

In front of the whole school, I knocked out a second-grade genius who had provoked me with one punch.

Everyone: “??? Did this pretty boy cheat?!”

I laughed. Cheat? No, I just treat the ferocious beasts you fear as my experience points!
