Summon Heroes from Another World to Conquer the World

You say you are unparalleled in bravery, but how do you compare with Xiang Yu? You said you are as smart as a demon, but how do you compare with Zhang Liang? You said that you are like a god in using soldiers, but how do you compare with Bai Qi? The good old man Qin Rang traveled to another world with a system for summoning heroes. In his previous life, he was kind to others but was betrayed by his brother and woman. In this life, as an emperor, he rules the world. My name is Qin Rang, and I don't give in humbly, but in a responsible way. Beauty, mine. The world is mine. Divine weapons, supreme elixirs, whatever I like is mine.
