Marriage License: From the Start, I Become Sai Tianjiao’s Supreme Guardian

[Transmigration + No System + Male-oriented + Decisive in killing + No saintly protagonist + No romance] I hope you enjoy the story!

In a battle led by the Heavenly Primordial Venerable, thirteen Apostles fought Unicron. The Apostles' Supreme Guardians also joined the fight against Unicron. After the Heavenly Primordial Venerable and the thirteen Apostles defeated their foe, the Venerable became the AllSpark of Cybertron, providing the planet with an endless source of power.

After the war, as the battlefield was being cleared, they discovered that nearly all of the Apostles' Supreme Guardians had been wiped out. Sai Aotian was one of the lucky ones. When Tianyuan found him, his body was severely damaged. Sai Tianjiao used his immense power to build Sai Aotian a powerful new body. But since it wasn't his original body, Sai Aotian had to adapt to it, and fell into a dormant state, intending to wake once his body and energy core had fully fused.

Unexpectedly, Li Yao transmigrated into one of these bodies. I hope the story that follows will interest you.
