Why did Quinlan, the blood clan, kill the blood ancestor?

Because Blood Zu wanted to kill Quinlan, Quinlan killed Blood Zu for revenge.

Quinlan starred in the TV series "Blood clan" season 2 episode 5. He was a gladiator in the Colosseum in ancient Rome and disappeared with the fall of the Roman Empire. After being injured by Setrikian, the blood ancestor reappears and will return to the field of vision with the image of justice.

In Roman times, the blood ancestors were parasitic on a teenager, who was a red man around the emperor and only sucked the blood of virgins. Later, an oversight took a sip of the pregnant woman, killed the fetus before it was born, and then there was Quinlan. Quinlan doesn't have blood worms in his body, and he doesn't have to listen to his blood ancestors, but he does have his blood.

Later, blood ancestors have been after him. Then the ancestors asked him to cooperate, and he refused. However, the blood ancestors later transformed Quinlan's wife and daughter (the wife was a widow, and the daughter was brought up by her, and Quinlan loved her very much), which strengthened Quinlan's determination to retaliate against himself.

Final outcome

Although the blood ancestor has high ability and outstanding fighting capacity, he is very allergic to ultraviolet rays and water, and Quinlan has a natural fear of ultraviolet rays and water, but his resistance is much stronger than that of the blood ancestor. In all the battles, Quinlan is basically invincible, and no one can beat him.

But because there is no blood worm in Quinlan's body, he doesn't need to obey the command of blood ancestor completely, and blood ancestor has been after him in the later period. Quinlan had to sacrifice his life in order to keep everyone's stable life. He was trampled to death by his own blood ancestors and became one of the greatest heroes of the play.
