What zodiac is the seven steps true son of heaven?

Snakes. A snake's weakness lies in its seven steps. If you are beaten, you will become a corpse (poem).

I think it's a snake, also called Xiaolong. The seven-step success story in history is Cao Zhi.

However, although Cao Zhi has the talent of an emperor, it's a pity that he didn't claim to be the emperor. His brother Cao Pi is the real dragon.

So he is a little dragon, so the answer is snake.

Seven steps snake come true! ! Not a dragon! ! !
