The Law of Rebirth of Cannon Fodder

[Main attack✖️Xian Xia✖️A little bit of blood✖️Continuous reversal] This is my first time writing an article, so I'm a noob at writing, so please forgive me~ Xiao Luoyu was an orphan. After he was adopted by the Immortal Sect, he worked hard to practice and became the chief disciple of the Immortal Sect. For him, the Immortal Sect was his home, but he died together with the Immortal Sect in the battle between immortals and demons... He originally thought that his life would end like this, but God gave him a chance and he was reborn! As soon as he was born, everyone regarded him as the proud son of Heaven. He lived up to expectations and became the second disciple of the No. 1 Immortal Sect Immortal Lord at a young age. Everyone called him a genius who cultivates immortality once in a thousand years. However, for the sake of the safety of the Immortal Sect, such a proud son of Heaven was even willing to become the Demon Lord's plaything... Once reborn, what kind of story will happen to these two people who have never met in the previous life?
