After Shang Yang lost power, why did all six countries issue credentials to kill Shang Yang to thank the world?

This is probably a novel or a TV series, which is not in line with historical facts.

After Shang Yang lost power, he fled to Wei, who refused to take him in, deported him and rushed back to Qin. Shang Yang had no choice but to return to the feudal city of Qin, rose to revolt and was finally killed by the king of Qin. There are no six countries that have issued credentials to kill Shang Yang.

Here I will analyze why Wei is unwilling to take Shang Yang in and deport him.

Shang Yang was originally a patriotic person. He hung out in Wei in his early years and took refuge in Guo Xiang's uncle and uncle. Uncle CuO appreciates Shang Yang very much. When he died, he recommended Shang Yang to Wei Huiwang, hoping that Wang Wei would hand over state affairs to Shang Yang. At this time, Shang Yang was just a little-known figure. Wei Huiwang thought uncle CuO was sick and delirious, and was obviously not interested in what he said. Uncle CuO saw it and said, kill Shang Yang without him, and don't let him go to other countries.

Wei Huiwang took uncle Cuo's earnest words before he died as a joke. When he returned to the palace, he told the people around him that Guo Xiang was really ill. It's sad. Isn't it ridiculous that he wants me to hand over the country to Sun Yang?

However, it turns out that Uncle Cuo is far-sighted. Later, Shang Yang went to the State of Qin and made a vigorous reform. As a result, Qin's national strength was greatly enhanced, and he began to overwhelm Wei militarily. Obviously, at this moment, Wei Huiwang realized that he didn't listen to his uncle, which was a big mistake. However, some people know their mistakes in their hearts, but they will never admit them. When Shang Yang was in trouble, Wei Huiwang could have taken him in, but it proved that he was short-sighted and ignored Shang Yang. Wei Huiwang, with a good face, could not afford to lose this old face, so he refused to take Shang Yang in.

Wei Huiwang not only has a good face, but also hates Shang Yang. Why?

Shang Yang's political reform harmed Wei. One of the contents of the reform is to abandon the mine field and open a building. Do your best to reclaim land and abandon it for territory? . At that time, Qin had a vast territory and abundant resources, and there were few people. Wei had four wars, and wars were too frequent, and people's livelihood was difficult. So Shang Yang dug up the foundation of Wei, vigorously introduced labor from Wei, gave them fields and houses, and allowed three generations to refuse military service. This not only increases the labor force of Qin, but also weakens the labor force and reserve force of Wei, which can be described as killing two birds with one stone.

If Shang Yang only engaged in political reform in Qin State, it would not be a big problem. It happened that Shang Yang personally led troops and attacked Wei several times.

In the tenth year of Xiaozong (352 BC), Shang Yang was promoted to the position of a big beam, which was also the highest official position of Qin State, equivalent to prime minister and general. This year, Shang Yang personally led the troops, crossed the Yellow River eastward, attacked Wei and surrounded Anyi City. Anyi is the old capital of Wei, and its importance is second only to Daliangcheng. The defenders of Anyi were forced to surrender to Shang Yang when the city was helpless.

A year later, Shang Yang led his troops into Wei again, surrounded Guyangcheng and forced the defenders to surrender.
