Star Prison

Li Tianlang, a taciturn high school student, is actually Monocerotis Sirius, one of the initiators of the third cosmic war. In the past, he was arrogant and free, and he rose up with all the transcendent to fight against the constellations, killing countless constellations. However, after the defeat, he became a lackey and was sealed as a prisoner of the Constellations. He was ordered by the Emperor to protect the earth from the invasion of Karma. Although he has endured 1500 years of oppression, he is still waiting for the opportunity to take revenge.
