At that time, the king of Qin was a very far-sighted monarch. He boldly used Shang Yang in politics and gave full support to Shang Yang when he proposed political reform and reform. Qin encouraged the people to cultivate, reclaim the fertile land originally occupied by wealthy aristocratic families and redistribute it according to the population. Secondly, the provision that wealthy aristocratic families do not pay taxes has been abolished, so that the state treasury can get a lot of silver income, and families who join the army at home will be rewarded, and soldiers will receive generous pensions after they die. These policies enabled Qin to prosper rapidly and strengthen its national strength.
At that time, there was a guiguzi student, Su Qin, an official. He couldn't stand the disputes between countries, which led to the loss of life in the world, so he traveled around and analyzed the interests of various countries. Under his lobbying, the other five countries formed an alliance to fight against the increasingly powerful State of Qin. However, although Wu joined forces, they were all superficial phenomena, and privately they all had their own selfishness. The so-called alliance was even more vulnerable.
And soon Su Qin's classmate Zhang Yi became an official. He and Su Qin have completely different ambitions. He thought that only the unification of the world could avoid war forever, so he chose Qin State. Then, under the authorization of the king of Qin, Zhang Yi started a conversation among countries, which soon aroused suspicion among countries. Su Qin's art of combination melted instantly. To sum up, it can be said that Qin's final success is inevitable.
