MTL - Yu-Gi-Oh!: Underworld Boss, Cancerous Creator God - Chapter 364

Yu Ziyou and Zhong Wan served different masters.

They had once been the closest of souls, and were the bitterest of enemies.

After losing the fight for the throne, Zhong Wan brought his two young masters with him far toward the borders for the sake of survival. He relied on the little friendship that existed between him and Yu Ziyou when they were young. He borrowed some of his personal belongings while also dropping various hints around which made everyone think that there was something intimate going on between them.

Given the Yu Clan’s powerful authoritative presence in the imperial court, this appearance of a close tie allowed Zhong Wan to live a much better life than before. As such, the stories he cooked up began to carry more and more weight.

As rumors of their lovely romance spread a thousand miles into the horizon, Yu Ziyou, who was located in the distant capital city, eventually caught wind of his deeply moving and epic love affair. In a trance, Yu Ziyou, who had been completely brainwashed for seven years, believed in them. He guessed something special really did happen between them back in those years…

The circle turned red, and when the smoke cleared, I was staring at the Tyrant Empress—a Calamity-tier villainess who nearly destroyed the world 800 years ago.Everyone calls me cursed. Dangerous. A threat that should be eliminated.They're right to be afraid.Because the Tyrant Empress wasn't the only one who answered my call.And unlike the others, my strength is forged in pleasure.Through forbidden dual cultivation with my villainesses, I grow without end.My name is Cade Marlowe, and I don't summon heroes.I only summon villainesses.
