At that time, Chu Huaiwang and Liu Xiangyu had a contract. Whoever gets Xianyang is the king of Guanzhong. Xiang Yu's fighting ability is obvious to all, so he met powerful enemies, such as Zhang Han's big army. Of course, this battle is also very beautiful. The so-called battle of the giant deer suddenly achieved the title of God of War, and no one in the army dared to look forward to it. As for Liu Bang, he is good at fighting without bloodshed. Liu bang has capable people under his command and often likes to use tricks. Liu Bang marched into Shaanxi Pass.
As the traffic artery between Nanyang and Guanzhong in ancient times, it is easy to defend but difficult to attack. It is the throat fortress leading to Xianyang and Qin Dou, and also the last pass to defend Xianyang, which is guarded by Qin heavily. Before reaching the pass, Liu Bang wanted to command more than 20,000 troops and forcibly capture them. Sean advised: "At present, Qin Shouguan's strength is still very strong, so we must not act rashly." Liu bang was afraid that Xiang Yu's army would enter the customs first, so he was worried and asked Sean for advice. Sean knew that his fighting capacity was not strong, so he gave Liu Bangxian a coup.
He said, "I heard that Shanguan, the commander, is the son of a butcher. Such a small philistine can touch his heart with a little money. We can send advance troops to prepare the salary of 50 thousand people, add a large number of military flags on the surrounding mountains, and bluff as suspected soldiers. Then send Li Chi to convince Qin Qiang with more treasures, and things may be successful. Li Shiqi came to Qin Jun Barracks with a lot of gold, silver and jewels, and the generals couldn't wait. When they saw the money, they were in high spirits. But the Lord said no, the law of Qin was very strict, and adultery with the rebels would be beheaded. Not only killed himself, but also killed his family. The Lord said he should think twice. In the evening, the two lieutenants tied up the master and let him go.
Liu bang was very happy when he saw it. He was about to join the army, but Sean refused. He said: this is just the idea of the commander-in-chief, and the soldiers may not think so. If there is a mutiny, we will definitely be caught between Scylla and Charybdis. It is better to March quickly. At this time, Qin Jun's morale will definitely collapse. Liu Bang thought it was the right thing to do, so he sent troops to Qin Jun, and the result was a crushing defeat.
Wuyi fell, Liu Bang's army marched into Xianyang City, and Zi Ying, the king of Qin, was helpless. Although he personally killed Zhao Gao, he could do nothing about Daqin and had to surrender to Liu Bang. Liu bang walked out of the team and was worthy of the people. He agreed with the Qin people not to commit crimes in the autumn, and then withdrew his troops to dominate, waiting for the arrival of Xiang Yu's army.
