My Heart Was Dug Out at the Beginning, I Transplanted the Heart of Immortals and Demons

Nangong Liuyun, who possesses the innate holy body, has been snatched away by various forces since his birth. His heart, precious bones, and eyes were poached one after another... He managed to survive, but the various forces did not let him go. In his twilight years, his family suffered a disaster. His personal maid risked her life and sent Nangong Liuyun into the river. No one knows that at the end of this nameless river is the legendary Demon Temple, where four peerless masters actually live. They have lived in seclusion in the Demon Temple for tens of thousands of years, suppressing the Demon God's heart so that he cannot go out and cause harm to the world. It happened that the Demon God's Heart was rioting, and the four of them could not suppress it, so they had to take a desperate risk and transplant the Demon God's Heart into the body of the dying Nangong Liuyun. The ruined innate holy body and the violent devil's heart miraculously merged, and a peerless ferocious beast was born... This novel and its characters are purely fictitious.
