MTL - Conan: Open the Door, I’m a Policeman - Chapter 4 hate detective

After an ultimate battle against the King of Hell Lucifer, Asmodeus, the Vampire Emperor, has fallen. Although he lost, he died without regrets and with a smile, prideful that he had managed to corner the King of Hell himself to such an extent.

However, due to a sick twist of fate, Lucifer himself decided to reincarnate him into the feeble body of a human child named Blake, desiring a rematch in the future!

Now, given a new opportunity at life, Blake will use every possible way to grow stronger and protect his new family in a turbulent world where people can summon spirits to fight and develop their magical powers.

Armed with only a Grimoire, he’ll slowly summon all of his previous life subordinates, who are all powerful Vampires, and rise to the top while fighting the ever-growing menace of the Demon Towers.

Accompany Blake through a journey filled with excitement and growth and experience the rise of the Vampire Emperor. A new Era of Blood is about to begin.

He is the ruler of the mercenary realm, an overlord that gives headaches to the leaders of any country! For the sake of his friends, he’s willing to sacrifice himself; for the sake of his family, he does not hesitate to spill blood! He is a dragon, one that soars above even the highest of heavens. He’s a power that advances triumphantly through unstable situations, stirring up both the winds and the waters.

So called ‘gods’ neither want nor desire anything. They’ve seen through the vanity of the mortal world and are outstanding amongst all living beings.

After being betrayed and murdered by his lover of 11 years, “Heavenly King” Qi Wenyuan is reborn as the entertainment circle’s number one vase, Lin Xi.  Good and evil will each meet their due according to natural laws. Those who doubt, raise their heads: who will the Heavens spare!

But…the mantis stalks the cicada, unaware of the oriole behind. Heavenly King Qi, have you really not noticed a certain man…behind you?

He’s the only God of Show Business, the one who’s been secretly in love with its Heavenly King for years. After a certain Heavenly King’s rebirth, he’s finally (?) fulfilling his aspirations for romantic love. From then on, the great deity found himself a partner, leaving the entertainment circles with no god.
