Records of emperors and Generals

I grew up listening to the story told by my grandfather. In his mouth, King Zhou of Shang Dynasty is a powerful emperor, Emperor Qin Shihuang is a great immortal, while emperor Gaozu of Han Dynasty is a sinister hypocrite, and Emperor zhaolie is a kind-hearted miser. It is said that they are the strongest who can attack heaven and attack hell! Flying through the clouds, killing demons with the sword, carefree and willful, omnipotent! But I was thinking, is there really an immortal in this world?
