In the Soul Society, He Followed Aizen and Became the Soul King.

This book is also called Undercover Aizen. Sorry, I am the ultimate villain. Kitahara traveled through the Shinigami and became a Shinigami. As a result, he accidentally stumbled into Aizen's conspiracy and was forced to become Aizen's subordinate. Fortunately, the villain system appears. As long as you stay undercover and complete tasks beside Aizen, you can get rewards. The higher the task completion evaluation, the better the rewards. Beihara thought, isn't this kind of thing simple? "I asked you to form the Ten Blades, but you ruled Hueco Mundo?" "I asked you to capture Bengyu, how could you defeat Soul Society!" "The Quincy invaded, why did you kill all their bosses instead?" When the dust settles. Aizen finally smiled and expressed his true gratitude to Kitahara, and then pulled out Kyoka Suigetsu towards Kitahara. Beiyuan stopped pretending when he saw this. He wiped his hair with his hand and said, "From now on, I will stand in the sky!" Aizen: *Ma, isn't this my line? This novel and its characters are purely fictitious.
