At the end of Qin, Yang Ren took Fan Zeng (Xiang Yu's second father) as an apprentice, gave him a piece of jade, and opened his eyes for him to see everything in the world.
Yang Taiyi's other abilities were not high, but that pair of divine eyes was extraordinary, paying attention to the upper view of the heavenly court, the lower view of the nine shadows, and the middle of looking at everything in the world. Although Fan Zeng had only learned one, it was already an invincible existence in the human world.
Therefore, the Hongmen feast, the whole world feels that the little bastard Liu Bang has no hope, but Fan Zeng found that this guy is multicolored on the top of the clouds, in the shape of a dragon and a tiger, and must be the son of heaven, so he asked Xiang Yu many times to remove it, but unfortunately no one cared, and the result was that the Chu Bawang was destroyed by Liu Bang.
And that too old Yu Jue is also extraordinary, just as the so-called too old is about to fall into trouble, no matter whether it is a human immortal, it is just Fan Zeng holding a picture of Yu Jue, which immediately makes you unlucky. And there are many disasters and minor disasters.
Therefore, when Fan Zeng was alive, Liu Bang's men said that there were many talents, xiao He, Han Xin, Zhang Liang, Chen Ping, and Fan Duo, all of whom were top figures in the world, but as soon as they encountered Xiang Yu's army, they immediately scattered birds and beasts, and many times they were crushed at a touch. Even Han Xin, who was the best at using soldiers, could only carefully avoid Xiang Yu's main force and play side drums everywhere.
The reason was that this piece of jade in Fan Zeng'er's hand was too powerful, and if one accidentally was illuminated, he would be unlucky. Only later, Chen Pingshi counter-plotted, let Xiang and Fan fall out, and finally Fan Zeng vomited blood in anger and died, and the Han army was relieved, and successive defeats turned into victories, and finally trapped the Chu Overlord under the sword.
