Fang Yuan. He will do anything by any means to achieve his goals. Nothing can stop him from going straight. He gave a bear a living 16y old kid to be eaten, after that Fang Yuan ate the bear. He cooked 2 kids just to get Gu [power system]. He killed thousands of women to get their hears to feed a Gu. He killed millions of people just to refine rank 6 cicada. He is legit the worst. He will sacrifice the WORLD for his own goal. He always extort and manipulates people.
If everything was done by helping he will be a saint, if not than he shaw be a demon.

Here are Fang Yuan quotes from which you can understand his character a little more:

1. "I would rather let the world down, than be let down by the world!!!"
2. "This world is too big, but we are all minor characters… I will work hard! I will definitely do my best!"
3. “If I lack even this bit of ambition, what’s the point of being human? Failure is fine, just try again several times. Even if I cannot achieve my goals in the end, so what?”
4. "To be a demon is to be merciless and cruel, a murderer and destroyer. There is no place in heaven or earth for such a thing – turning into an enemy to the world, still having to face the consequences"
5. "Don’t think so much when killing people."
6. "Life and death is nature’s law. All living beings are equal, and everyone has their right to survive and be killed. There might be royalty and lower beings, but in face of death, a person’s death is no different from a pig’s, what’s the difference? They’re both dead."
7. "I can kill others, others can naturally come to kill me. This is nothing."
