Yuzhi Longwang Kang Suoyou

Me: "Hey, you ate me! The least you can do is give me some compensation, right?" Dragon King: "Fine! I'll give you a cultivation technique on an advance. You get the knowledge now, and you can complete the training later!" Me: "How is that enough? I had to smell your rancid breath! That's double the mental damage!" Dragon King: "Then what do you want!?" Me: "From now on, we're two immortals sharing one HP bar. You're going to tank all the damage!" Dragon King: "Fuck! You lunatic! Why does the health bar for this majestic, sovereign body of mine feel a little short all of a sudden? Looks like it's time to go out and get a job!" (Source: Bilibili Comics, translated)
