There are several streams formed by mountain springs.

Meng Yi sent people to boil a large amount of croton, packed it in cowhide bags, and sent 100 people to secretly go up the mountain to lurk. When Zhao Jun fetches water for cooking, he dumps a large amount of it on the spring.

There was no way to test the toxicity of croton water in ancient times, and Zhao Jun simply tested the poison with a silver needle, and then watched the live fish jumping around in the water, so he naturally did not suspect it.

But by the evening of the same day, there were thousands of diarrhea Zhao soldiers in the entire Zhao army camp.

"What's the situation, why is no one checking the water source?" Zhao General Zhao Cong was furious, fortunately, some of the soldiers drank the water they had hoarded yesterday, otherwise the whole army would have to lie down today.

"General, the little figure has carefully checked the water source, and found nothing wrong, the silver needle is normal, and the live fish are also normal!" The captain of the battalion was very frightened, but he still told the truth.

"So, the enemy dropped an unknown poison?" Zhao General Zhao Cong was shocked, "Order the whole army to secretly pull out the camp, and withdraw to Yan He first." ”

It's a pity that the Qin army had already prepared and set up an ambush on the road. Only 5,000 of the 20,000 Zhao troops successfully withdrew to Yanhe, and the Zhao general Zhao Cong was embarrassed.

At this time, there were only 20,000 defenders left.

Zhao General Zhao Cong simply pulled Zhuang Ding in the whole city, and piled up 30,000 young people to the city in one go.

"Lao Tzu doesn't believe it, 50,000 people can't defend a city." Zhao General Zhao Cong was ruthless, and at the same time, for the sake of insurance, he also sent a request for help to General Zhao Guo.

At this moment, General Zhao Guo had a headache at the moment, because the other two Qin troops had spent most of their troops, where were there reinforcements to rescue Zhao General Zhao Cong. At the same time, the general of Zhao also understood that in addition to King Zhao's forbidden army in Handan City, the rest of the mobile forces were also evacuated. In the entire Zhao State, except for Li Mu in the north, where are there any idle troops. However, Zhao Yan, the king of Zhao, obviously did not want to give up the city in the north, and in desperation, the general of Zhao had no choice but to order Zhao Cong to defend him.

The Qin army battalion.

"Dashuai, the small test of croton laxative was successful. Moreover, the last general also found that the water source in the city was basically drawn from the spring water in the mountain. Meng Yi was very happy to come to report.

"Really?" When Wang Jian, the general of the Qin army, heard this, he was overjoyed.

"There are black-clothed guards in the city, and it is determined that the terrain of the city is too high, and the wells are often dry and lack of water, so the water sources in the city are all drawn from mountain springs, even the moat." Meng Yi explained in detail.

"Father, this is great, not only can most of the soldiers in the city lose their resistance, but also take the opportunity to cut off the water source of the moat." Wang Ben was also very excited, this battle was too easy to win.

"Marshal, I suggest that the water source be officially cut off in five days, so that the soldiers in the city will basically be unable to resist, and the moat will no longer be a moat." Meng Yi suggested.

"Why five days? Throw croton today, and tomorrow you can cut off the water source and launch an attack. If you break the alliance as soon as possible, you can take advantage of Li Mu's not yet going south to swallow the army of Zhao State, so that Handan is not at your fingertips? Wang Ben said anxiously, eager to attack the city of Handan immediately.

"After eating croton, laxatives are diarrhea, and there is also a gradual process. If you pull until one day, you can usually stand, and on the second day, you have to squat, and on the third day, you have to lie on your stomach. Everyone said, is it better to let the soldiers of the Zhao army stand? Or is it better to let the soldiers of the Zhao army lie on their stomachs? Hahaha........" Meng Yi couldn't help but ask.

When the crowd heard this, they burst into laughter.

At dawn, the city guards the palace.

Zhao general Zhao Cong and deputy general Yan Ju stayed awake all night.

The city is stinky, and it can be said that "the sorrow is everywhere"!

In just five days, the soldiers and young men in the city basically lost their combat effectiveness, except for a few officers and personal guards, basically tens of thousands of Zhao troops were "crippled".

"General, the Qin army has cut off the water source, how can this be good? Without a water source, the army can't carry it for three days. Adjutant General Yan Ju came to report.

"Hmph, even if they don't cut off the water source, Lao Tzu won't dare to drink this spring water. The order went down, and let the young men who were safe and sound go to dig wells. If you want to cut off the water, you will force Lao Tzu to admit defeat, no way! Zhao General Zhao Cong said with a grim face.

"General, the well water is barely enough for a few days, but what about the tens of thousands of soldiers with severe diarrhea, now they don't even have the strength to stand up." Adjutant General Yan Ju once again said a headache.

"What the hell is going on? Didn't Lang Zhong say that he was not poisoned, why didn't he get better in a few days? Zhao General Zhao Cong was furious. These days, he and his guards eat and drink specially made, so they are safe. However, the stock of clean water in the city is limited after all, and it cannot supply the needs of the garrison.

"General, the last general heard that there is a medicinal herb in the land of Bashu that can make people have diarrhea, and it is colorless and tasteless, and it cannot be tested for toxicity." The deputy general Yan Ju also happened to hear what the Bashu businessman said, and at that time it was just a fun thing after tea and dinner, but he didn't expect to be used as a secret weapon by the Qin army today.

"What? Is there such a thing in the world? Do you know how to crack it? Zhao Jiang Zhao Cong asked eagerly with a hint of luck.

"The last general heard from the folk Langzhong that it can be expelled by decoction. However, there are limited medicinal materials in the city, so I'm afraid it's a drop in the bucket! The deputy general Yan Ju was also distressed, who would have thought that tens of thousands of Zhao troops would be defeated by the Qin army with one move.

"No matter, as long as there is a group of soldiers who can stand, the city must not be lost!" Zhao General Zhao Cong doesn't care about 3721, as long as there is a group of soldiers to defend the city, he will not be willing to give up the important town. Because Yan He is too important for Zhao Guo, which is now enemies on all sides.

"General, the last general thinks that it is safe to let General Li Mu go south. Otherwise, there are few soldiers in the city, I'm afraid it will ......" Deputy General Yan Ju did not say any more, in fact, this truth, looking at the entire army of Zhao State, almost everyone knows it, and no one knows it. However, Zhao Yan, the king of Zhao, is reluctant to give up a few desolate cities in the north, he is really a short-sighted miser!

"Hey, this is not something we can decide, I hope the king will figure out the key as soon as possible, otherwise it will ......" Zhao General Zhao Cong also said helplessly.

Suddenly, there was a shout of killing from the direction of the south gate.

"Report, general, no, the Qin army has come in! The South Gate is lost! The captain of the South Gate was covered in blood and had several crossbow arrows stuck in his back, and stumbled in.

"What? The gates are broken? What do you eat? General Zhao Cong was furious, "The south gate is the most heavily defended place, how can the Qin army be allowed to touch in?" ”

"There are spies in the city...... Under the cooperation of the Qin army, the south gate was broken. Everyone couldn't stand up, let alone resist...... The general leaves quickly, otherwise it will be too late......" Captain Nanmen swallowed his breath after speaking. This is a loyal subordinate, and before he died, he did not forget to come to report the news.

Zhao General Zhao Cong cried bitterly, and quietly closed the eyes of the captain of the South Gate.

"Tens of thousands of troops, before they have fought a few real battles, they have completely lost. What kind of face do I have to meet the king......" When Zhao General Zhao Cong was pessimistic, he actually wanted to draw his sword and kill himself.

Adjutant General Yan Ju hurriedly stopped Zhao General Zhao Cong's reckless actions.

"General, General Zhao Guo is dead and gone, don't be stupid. When the king knows what is going on, he will be tolerant of you. What's more, it's not your fault, it's really that the Qin people are too despicable. ”

"Yes, General. There are not many generals left in the Zhao State, you must save your useful body and seek justice from the Qin army in the future. The surrounding guards were also frightened and dissuaded, after all, the Lord will commit suicide, do they still have a way to live?

Zhao General Zhao Cong just couldn't think about it for a while, remembering that Zhao Guo had not yet been defeated, "Let's go, let's go back to Handan and ask the king for his guilt." ”

Zhao defeated Zhao Cong, his face was ashamed, and he fled back to Handan.

The Qin army took the important town of Zhao with almost no effort.

"Sun Tzu said: Those who count the temple without a fight have to count a lot; The temple is not victorious without a fight, and it is considered to be less. More wins, less wins, and nothing counts! Wang Qian, the commander of the Qin Army on the North Road, said with a smile, "Meng Yi, you kid, there are really too many ghost ideas. ”

"The marshal praised it falsely, the terrain situation of Yanhe is too special, and cutting off the enemy's water source is so effective. In addition, the overall planning of the marshal is naturally indispensable. Otherwise, how could it be so easy to take this place. Meng Yi replied modestly.

Meng Yi remembered the "Ma Tan Lost Street Pavilion" during the Three Kingdoms period in later generations. In 228 AD, in order to realize the great cause of "setting the Central Plains in the north and reviving the Han Dynasty", Zhuge Liang personally led a large army to the north to attack Wei and attack Qishan. Because the Shu army had strict military discipline all the way, high morale, and successive victories, Cao Wei Nan'an, Tianshui, Anding and other Longxi counties rebelled against Wei and surrendered to Shu, and the sound was in Guanzhong for a while. Emperor Cao Rong of Wei Ming hurriedly rushed to Chang'an from the capital Luoyang, and ordered the general Zhang He to lead his troops to resist. Zhuge Liang sent Ma Jian to join the army to "supervise the army in front and fight with He in the street pavilion". Unexpectedly, Ma Jian disobeyed Zhuge Liang's order, and did not listen to the dissuasion of the deputy general Wang Ping, so he made his own opinion, "relying on Nanshan Mountain, not going down to refuse the city", not near the water, and camped the army on the mountain. Cao Wei's general Zhang He learned that the Shu army was camped with a high position, and drove the army into a swarmed army, besieged on all sides, cut off the road down the mountain to get water, and trapped the Shu army in the mountain. A battle for street kiosks ensued. The Wei army took advantage of the situation to attack the mountain, but Ma Jian expected it difficult to hold on, and after a few days, he broke through and fled with a lack of troops. Wang Ping, who camped at the foot of the mountain, wanted to lead the troops to rescue, but when Zhang He blocked the road and fought, he had to flee in a hurry and retreat to Tianshui. As a result, the Shu soldiers were defeated and lost the street pavilion. Zhuge Liang had to retreat from Tianshui to Hanzhong. Zhao Yun's army also suffered a defeat in Keigu, but fortunately, after Zhao Yun personally broke off, the loss of the characters was relatively light. In the first battle of Jieting, the main force of the Shu army was defeated, which led to the overall defeat of Zhuge Liang when he first came out of Qishan. Zhuge Liang returned to Hanzhong, and in accordance with military law, beheaded Ma Jian and demoted Zhao Yun, and at the same time, Shangshu "please degrade yourself to the third class".

Ma Tan lost the street pavilion - exaggerated.

Meng Yi felt that there was another sentence of evaluation that was more appropriate, called talking on paper.
