A Person in Another World Is Tricked into Becoming a Demon by a Fake System

Traveling through time is risky, so be careful when reincarnating. Gilvi Lucifergus, born with black hair, is known as the "Ominous Son". If his father hadn't been fierce enough, he would have been burned on the rack as soon as he was born. Fortunately, he has a system. Although the system delays issuing rewards for three years. Although the rewards given by the system are vague every time, you need to explore the purpose yourself. Although the guard arranged by the system had a grudge against him in his previous life. Although the source of the divine power given by the system seems unclear. But Gilvey believes the system is a good one. It was not until many years later that Gilvi, sitting on the throne, accepted worship from living beings. "Tong, tell me why people outside have started to address me as His Majesty the Demon God."

Uh-huh, I'm sad.
