Summon Hero Killing System from Another World

Some people say that there are no two identical flowers in the world. Even if they are similar in shape, they are just two blooming flowers... If a time and space condition is added in front, who can tell the result? This is a troubled world, and it is also a great world where heroes emerge in large numbers. Let's see if our protagonist can become a trend-setter, and whether he can move the wheel of history and bring about a different scenery. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
