Getting Stronger By Healing? I Became A Martial God Through Refunds!

[The protagonist is a devil ➕ medical and martial arts dual cultivation ➕ sequence talent ➕ disease return ➕ multiple female protagonists ➕ slow-heating system ➕ first bitter and then sweet ➕ merit]

Yun Chen traveled through the world of high-level martial arts and became a useless doctor with no fighting power at all!

When his life was in danger, Yun Chen awakened the [Ten Thousand Times Return System for Medical Condition]. As long as he treated others, he could return the medical condition reward infinitely!

"Healing refund? That's great!" Yun Chen was overjoyed and made rapid progress.

[Ding! Congratulations to the host for curing the magic poison and returning the legendary bloodline, the Twelve-Winged Magic Sword Immortal! ]

[Ding! Congratulations to the host for healing the kidneys and returning the Longyang kidneys. One blood and one qi per second! ]

[Ding! Congratulations to the host for healing the Heaven-Slaying Powder, returning his super-divine understanding, and instantly comprehending the technique! ]

Just like that, Yun Chenxiu's life was destroyed, and he controlled the destiny of yin and yang...

................

I am a sword demon who slaughters people, with countless lives on my hands.

I am also a doctor who saves the world, and I possess the highest power of merit in the world.

If the Heavenly Dao is afraid of me and wants to kill me, then I will accumulate the power of merit infinitely. When the Nine Mysterious Merits come to the world and the golden light shines upon the world, will the Heavenly Dao still dare to kill me, the Sword Demon?

When the whole world sees my great merits, but still wants to kill me, the sword demon.

But I laughed out loud, "Hahahahahahahaha! Master Immortal, I understand!

"Heaven wants me to be a saint? I want to prove the truth with demons!"

"People respect my reputation as a medical genius? I laugh at them for not knowing the devil!"
