After that, Liu Bang became stronger and made Han Xin a general to fight against Xiang Yu. In order to confuse Xiang Yu, Han Xin sent troops to build a plank road, which was very slow and took a lot of time. Little imagine, this time, Han Xin has been secretly marching to his position. Soon, Han Xin captured Xianyang and occupied Guanzhong.
Han Xin used the method of "one bright and one dark" to cover up the darkness, and finally won a great victory. Later generations will expand the meaning of darkness and explain that the surface is a set of secrets. That is to say, take the method of feint, create illusion, deceive the enemy, take advantage of the opportunity of the enemy's misjudgment, quietly come to the other side of the enemy and then attack the enemy, thus taking advantage of it and winning by surprise.
"Chen Cang" also appeared in the Romance of the Three Kingdoms. Zhuge Liang's second northern expedition to the Central Plains led 300,000 troops to surround Chencang from the three passes. Zhuge Liang has long heard that Chen Cang is very strong, so Zhuge Liang has prepared a lot of siege equipment, which can be said to be a determined posture. Zhao Hao, the garrison commander of Chencang, has only 3,000 defenders, and is ready!
Zhuge Liang thinks that his strength is one hundred times that of Zhao Hao, and he doesn't take Zhao Hao seriously at all. He first sent his compatriots to surrender from Zhao Hao to Zhao Hao, and the answer was that Zhao Hao vowed to live and die with Chen Cang. Zhuge Liang failed to persuade him to surrender, so he ordered the troops to attack the city. Zhuge Liang thought it was easy to lay their position, but he didn't expect it to be broken after playing for more than 20 days.
Zhuge Liang started with a hundred ladders, and a dozen people could stand by and watch one ladder, surrounded by wooden boards, with the army beating drums and the hundred ladders attacking from all sides at the same time. Zhao Hao ordered three thousand troops to hold rockets in all directions. When the ladder approached the city, all the rockets were fired, and the ladder was exhausted. Most of the soldiers on the ladder were burned to death.
Zhuge Liang was furious: "You burned my ladder, but I rushed the car!" " Instead, they ordered people to transport stones, gouge their eyes, and fly through with a rope, and the cars they rushed were all discounted!
Zhuge Liang also sent people to borrow soil to fill the moat, led shovels and shovels to dig tunnels at night and secretly entered the city. Zhao Hao also ordered people to dig heavy trenches in the city!
In this way, it attacked day and night for more than 20 days, and there was no way to break it. At this moment, Cao Zhen and Zhang He's reinforcements were about to arrive, and Zhuge Liang ran out of hay and had to return in vain.
Many people wonder why it is so easy for Han Xin to attack Chencang, but Zhuge Liang can't attack it for a long time. I thought Zhuge Liang's capture of Chen Cang was a gesture of determination, and he only used an open plan!
Zhao Hao was ready, 300,000 troops attacked a small town of 3,000 people, but they couldn't attack it for more than 20 days. The morale of the army had already been scattered, but Zhao Hao became more and more brave. Han Xin, on the other hand, pretended to decorate the plank road, stole time, and hid the plot in an open plan, so he succeeded. Han Xin, the military god, conspired to use an open plan together, which is better than Zhuge Liang's relying on more soldiers and only using an open plan.
