Cangyuan Tu: I Want to Live, but I Can Only Let the Monster Die

After accidentally traveling to the world of Cangyuantu, Liu Lie only awakened his memory at the age of sixteen, and with him came the treasure "Time and Space Monument". 1: The speed of time inside the monument is 10 times that of the outside world 2: A strong man who can possess the past time and space. Liu Lie was very excited. With the golden finger, he would definitely become the most powerful god and demon in the world. I never thought that this treasure would absorb one's own lifespan every day, and those who possess it would have to pay extra lifespan. Ordinary people need to absorb 10 days of longevity every day. The gods and demons need to absorb 100 days of life every day. The Venerable needs to absorb 1,000 days of longevity every day. ... In an accident, Liu Lie discovered that after killing a demon, the demon's longevity could actually replace his own. From then on, there was a Demon Emperor in the human world, and in the long river of time and space, there was a Demon City Lord who hated evil as much as he hated evil. Someone asked: Why do you always exterminate all the great sinners? I replied: I want to live, but I can only let them die.
