How did Yang Jian finally become a broken fairy after his mysterious achievement in 1989?

I think there is also the meaning that Jiang Ziya has a crush on Yang Jian. But I also intentionally envy him.

Because Yang Jian was eaten by foxes and minks just after he went down the mountain, it is our common sense that people can't come back from the dead, and Jiang Ziya obviously thinks so, but Yang Jian came back alive, which overthrew Jiang Ziya's thought a little bit. Moreover, I think Jiang Ziya may think that Yang Jian is immortal, so he won't die, so I think Jiang Ziya may be jealous of Yang Jian, so even though Yang Jian made great contributions in 1989, he rarely made it, and Yang Jian is like wiping his ass. Only when Jiang Ziya is going to lose, will he urge the grain to arrive. May also be formed inertia, often when he is in trouble, will think of Yang Jian, so even if Yang Jian repeatedly made meritorious military service, Jiang Ziya will not reuse him.

I think it also means to reuse Yang Jian, because Yang Jian is really good. I still remember Yang Jian's master once said a word, "If it is 89%, it will be bombed in the middle, and it will win the world." From this sentence, we can see how high the master agrees with Yang Jian. What's more, he showed his ability as soon as he came out. He ate the fox mink that should have eaten him, and finally defeated Mo Lishou. Yang Jian demonstrated the indestructible function of Gong Xuan in 1989. Later, he borrowed seventy-two things to hide, avoiding the rope tied by Tu Sunhang and Yin Jiao Tianyin.

And although Yang Jian is a grain supervisor, he can't go into battle to kill the enemy, but he can often send the grain to the barracks in advance, turning the tables and saving Xiqiao many times, which makes Jiang Ziya have to remember the merit citation every time.

So I think Yang Jian's greatest use in food inspection is because he is fierce. After all, food occupies a great position in the army.
