It was expedient for Liu Bang to defect to Qin Jia, and it was an unexpected surprise for Lu to meet Zhang Liang.

Liu Bang and Zhang Liang came to Liucheng together, but found that Jingju, the king of Chu, and Qin Jia, the Shangzhu State, had gone to Pengcheng, and only Dongyang Ningjun remained in Liucheng (near Pei County).

Dongyang Ningjun seems to have heard of Liu Bang for a long time, so he still entertained him warmly, asked for warmth, and arranged it properly. At this time, it is not possible to welcome it, Dongyang Ningjun's spies have already heard that the Qin army is rushing over here, so all the troops Dongyang Ningjun will be hospitable. At the same time as Zhang Han attacked Chen County, another faction sent Sima Qu (Yin Nie) to the north to attack Chudi, first captured Xiangxian (now Huaibei, Anhui), and slaughtered the city! The government army actually did this bastard thing, how can they not die? The Qin army had already reached Dangxian (present-day Yongcheng, Henan) and was preparing to attack Pengcheng (present-day Xuzhou, Jiangsu), and the government generally had a tradition of fighting whoever was king.

As soon as people are unlucky, they really drink cold water and stuff their teeth, Liu Bang can only sigh to himself that he is unlucky, and finally found a master to rely on, after a few days of comfortable days, the Qin army was pressing, so Liu Bang was very nervous, with his current strength, to face the most elite Qin army at that time, that was tantamount to hitting a stone with an egg, and this Qin army had just won the battle, and the morale was booming.

However, Dongyang Ningjun was a man and was very righteous, so he did not hesitate to lead 10,000 horses to Xiao County (Xiao County, Anhui) to stop Sima Jun's northward advance, and arranged for Liu Bang to meet him in the back. The host worked so hard to save the king of Chu, the guests naturally did not dare to slack off, Liu Bang also took Cao Shen, Xiahou Ying and others to Xiao County in the southwest.

Dongyang Ningjun encountered the Qin army in Lutun, Xiao County, and set up a position, facing the elite of the Qin army, the Chu army showed fear. Sure enough, as soon as the Chu army fought a little, they were beaten by the Qin army, and they lost their armor. Dongyang Ningjun's courage was good, but the result was miserable. It can be seen that fighting a war is not just about courage. Sun Tzu said, knowing oneself and knowing one's opponent is the only way to survive a hundred battles. I would say that impulsiveness is the devil.

Liu Bangjun followed behind, the front was defeated, and the back also suffered, but fortunately, the generals under Liu Bang were fierce and fierce, so that Liu Bang's life was not worry-free. Liu Bang could only bring the people back to Liucheng, and when he saw Zhang Liang who was left behind, he was infinitely emotional: I almost couldn't see Mr. Zhang Liang comforted Pei Gong and said that it was okay, don't care, victory or defeat is a common thing in soldiers.

The battle of Xiao County knocked Dongyang Ningjun away, which was not a bad thing for Liu Bang, and the city fell into the hands of Liu Bang, according to Zhang Liang's plan, he first rectified the soldiers and horses in the city, collected the remnants, and then fought Dangjun to use it as a base area.

Fighting Dangjun, aren't you afraid of Zhang Han's attack?

Zhang Han was stationed in Yongqiu (present-day Qixian County, Henan), and his goal was to attack the Zhao State, and he had no intention of taking charge of Dangjun at all. So you can rest assured that he won't come, and he doesn't bother to come.

A strategist is a strategist. The idea is very clear.

Zhang Liang is not only a strategist, but also a military strategist.

His arrival brought different combat ideas and methods to Liu Bang's army, and this difference was first reflected in the Battle of Dangshan.

In order to defeat Sima Qu's army, it is necessary to outwit and not attack, because with Liu Bang's current strength, there is no way to storm and eat the Qin army. So Zhang Liang is going to show his hand.

In the era of cold weapons, fighting a war pays attention to the right time, place and people, and it is not necessary to occupy all three. In order to win this battle, Zhang Liang took advantage of the geographical advantage among the three talents, and chose a battlefield for the Qin army, Dangshan is a gourd-shaped valley, in this valley to ambush, the enemy is difficult to fly, even if it is lucky to highlight the valley, Dangshan is the place where Liu Bang was a thief a few years ago, and the people are very familiar with the terrain here, even if the Qin army can stand out, it has to be peeled off. Besides, this General Sima is also a dumbfounder, although he is brave but he doesn't like to use his brains, so it is not difficult to lure him to Hulu Valley.

The arrival of the great strategist Zhang Liang did bring changes to Liu Bang's army, and it no longer relied on rampage to grab territory.

Zhang Liang arranged for Xiahou Ying to go out to battle tomorrow to lure the enemy, only to lose, not to win. Fan Xu, Chai Wu, Jin She, and Wang Suck were ambushed at the entrance. Cao Shen and Zhou Bo were ambushed at the exit. The two brothers, Ji Xin and Ji Yi, squatted on the upper right side of the valley with fire tools. Xi Juan and Xue Ou also squatted on the upper left with firearms.

This is indeed a perfect trap, just waiting for the stunned Mr. Sima to step into it.

After the plan was in place, Xiahou Ying brought a thousand people to the war. Mr. Erzi really couldn't help scolding, rushed out of the camp and fought with Xiahou Ying, the cliché shot came, Xiahou Ying fought for dozens of rounds, pretending to be invincible, and ran back, at this time Liu Bang rushed out again, fought with Mr. Sima, and was invincible, turned around and ran, and didn't even want the camp. Under the joint appearance of Liu Bang and Xiahou Ying, Mr. Sima became murderous and prepared to chase Liu Bang's defeated army, and the left and right generals reminded him not to fall into an ambush, but Sima Yu scolded, little thief, what kind of trap can there be. At this time, Sima Qu saw the opportunity to make meritorious contributions, can he let it go? Therefore, regardless of dissuasion, he led his troops to chase after him.

When the Qin army was introduced into the Hulu Valley, Liu Bang and Xiahou Ying patrolled the mountain road and pretended to be defeated on the ridge.

Right away he couldn't laugh!

When laughing, only to hear a cannon, the sound of killing shook the sky, the fire was dazzling, the rocks, fire smoke, sharp arrows were everywhere for a while, at this time Sima Qu knew that he was fooled, the sound of fire in the valley, screams, boulders rolling down, mixed together, the scene was very chaotic, Sima Qu organized the army to break through to the exit of the valley, but as soon as he arrived at the mouth of the valley, he immediately shouted to kill, and he realized that he had been wrapped dumplings.

In desperation, he had to retreat back to the valley, Sima Yu expected that he would not be able to stand out, so he had to draw his sword and kill himself, but he did not die under the persuasion of his entourage, and under the guidance of the local soldiers, he found a path from the valley, took a few followers, and escaped at night.

The next day, the Qin army, who was trapped in Hulu Valley, saw that the main general had run away, and they had no intention of fighting, so they went out to surrender Liu Bang. Liu Bang suddenly got more than 10,000 pawns, and he was overjoyed, but it was a pity that Sima Qu ran away.

According to his own words, he has not been so happy since he started the army, and Mr. Zhang is really the reincarnation of Sun Wu. And this big victory was achieved thanks to Zhang Liang's clever plan. Therefore, Zhang Liang is more and more important, worshipping Zhang Liang as a military advisor, and almost obeying his words.

Dangshan won a big victory, Liu Bang launched an attack on the counties in the county according to Zhang Liang's plan, and soon after, most of Dangjun had belonged to Liu Bang, of course, in addition to Fengyi, Yongya can also endure it very much. Liu Bang's great victory, according to the etiquette symbolic to Qin Jia, Qin Jia listened to the words of Dong Xuan, and only sealed the official position of the city order to Liu Bang, and Dong Xuan, who had not built an inch, was the magistrate of Dangjun.

This kind of shameless behavior of living the dead and losing the life to others, and the victory and victory of the battle to their own shameless behavior made Liu Bang and others extremely indignant, and they demanded that this villain be destroyed. At the critical moment, Zhang Liang said, don't be anxious, the world is still in chaos, reputation is not important, the most important thing is to preserve strength, go back to Pei County first and then make plans.

So Liu Bang led the troops back to Pei County, and these cities were gone. Dong Qian symbolically chased after him, just for show, he still wished that Liu Bang would leave, and he would be the magistrate of Dang County.
