Xue Ju discussed with the strategist late at night to find a good strategy to break the city, but throughout history, the guardian has had the advantage of geographical advantage. Apart from digging holes, flooding, internal and external cooperation, there is no good strategy for sneak attacks.

"Your Majesty, I have a plan, don't you know whether to speak or not?" The speaker is one of Xue Ju's confidants. He has a low official position, but he is one of the court aides. He uses a vicious plan and is not suitable for being the prime minister. The Secretary of the State is a talent who uses strange plans and is named Ke Feng.

"What a plan, even if it's said."

Ke Feng had slender triangle eyes, high nose bridge, and three-dimensional facial features, but his eyes were like rat eyes, which were scheming characters at first glance. His eyes slanted and then said: "After a few days of attack, we pretended to be huge casualties and could not break the city, we deliberately withdrew our troops, so that the Tang army would relax our guard, and then... we were thrown into the Jing River. Because the water level in Longyou was high, ordinary well water could not meet the needs of the Tang army, so we would definitely use the Jing River to drink. As long as we poisoned it, the Tang army would be weak and naturally be able to easily take down Gaoqian City."

As soon as this plan was made, Hao Yuan, Chu Liang and others were surprised, with strange eyes, and looked at Ke Feng, with some fear and disgust. Although this kind of person uses tricks, he uses all means and has a poor character. He is a person without principle among the counselors. He is not a despicable method, as long as he achieves his goal.

Xue Ju hesitated and sighed: "If you use poison, I'm afraid that a large number of dead fish will appear in Hanoi before the Tang army has drunk water. Tang army will know that, the logistics guys will use silver needles to test the poison, and they will know that the poison is contained in the water, which is difficult to work."

Ke Feng smiled and said, "It is not to use murderous poison, but mainly infectious diseases, such as dysentery, plague, cholera, etc. We secretly put some odorous and corroded mice, livestock internal organs, etc. into the river at night, and at the same time, we poured other juices that can cure diseases and powder. The amount was small in the early stage and the dosage was constantly increased, so that the military and civilians in the city would be infected with this disease without knowing it. At most one month or more days, the defenders in the city would be infected with the epidemic, dysentery, bloody stools, and dizziness, and then they would be infected with the epidemic, dysentery, and dysentery. At that time, the combat power of the defenders was afraid that there would be three layers left. How to resist the fierce attack of our Western Qin army!"

After hearing this, Xue Ju was a little shocked. After a while, he came to his senses and nodded slowly and said, "Although this plan is poisonous, it works. I will leave this matter to you with full responsibility. If manpower and material resources are needed, please come up with it. Once the city is broken, you will remember your first achievements."

Ke Feng bowed and said, "I will do it and live up to Your Majesty's trust."

In the next few days, the Western Qin army continued to attack the city, but the scale was reduced. They only fought for half a day a day and rested in the afternoon. Seeing that the momentum was declining, they were far less powerful than the previous few days, and their sharpness was revealed.

Li Shimin, Fang Xuanling and others were all excited, thinking that this way of waiting for labor, taking advantage of the city's benefits, not being able to stand firm and defend, was the main means to restrain the Western Qin army and was quite effective.

A few days later, the offensive of the Western Qin army became once every two days, and people were sent outside the city to yell and scold, wanting to fight with the Tang army in front of the formation and not fight the siege.

"Haha, look, the Western Qin army will not attack the city, and it has been severely damaged these days. If you want to provoke the generals and lead our army out of the city to fight, you will not be angry. Don't be fooled!" General Murong Luohu stood at the top of the city and couldn't help laughing.

Liu Hongji also let go and said, "Siege is a battle of consumption. Without excellent weapons and elite soldiers, it is difficult to fight in one go. Our army has sufficient food and grass, and many soldiers and generals are wide. It is no problem to support for three months. If the Western Qin army attacks for three months, it is estimated that these 200,000 troops will lose two-thirds."

Li Anyuan said: "If this continues, the Western Qin army will retreat soon after."

Five days later, the Western Qin army indeed began to retreat, and some of the troops left first, retreating dozens of miles westward.

This is Xue Ju's attempt to paralyze the Tang army and withdraw some non-combatants, wounded, baggage soldiers, etc., which creates an illusion for the Tang army and makes them relaxed in their vigilance.

Gradually, more and more soldiers in the city had diarrhea, and many people suffered from acute intestinal infectious diseases. The most direct manifestations were dysentery, fever, daily abdominal pain, severe internal and secondary pain, and even bloody stools. There were very few doctors in the city, military doctors, and there were no anti-inflammatory drugs or special drugs. Many soldiers began to die due to such problems, and even some wounded people with poor physical condition.

Not to mention these ordinary soldiers, even generals, some of the counselors also had symptoms, among which Li Shimin suffered from dysentery.

Originally, he loved to play with guns and was physically strong and not easily sick. However, since he led the army, he has consumed a lot of energy. He reviewed military affairs every day, lacked enough sleep, and tried his best to think about strategies to break the enemy. He did not pay attention to diet and drank a lot of raw water with infectious toxins, which led to illness in bed.

On this day, Liu Hongji, Fang Xuanling, Liu Jing and other advisers gathered together to discuss whether they should withdraw their troops and give up Gaoqian City.

Fang Xuanling analyzed: "The military and civilians in the city have this disease, and now there are more and more infections. The military strength is not ten or three. Many people have poor physical fitness and cannot afford medicine. A large number of deaths have occurred, and even plague and cholera have occurred. This city will become a dead city in less than a month and cannot wait and need to retreat."

Liu Hongji asked: "How is the second young master?"

Liu Jing said worriedly: "His condition is also very serious. He has fever all over and has blood in the stool several times a day. He must be sent back to the capital immediately to seek medical treatment from the imperial doctor. Otherwise, if time is delayed for a long time, I am afraid that I will not be able to save my life."

Liu Hongji snorted: "It must be done by the people of Western Qin. This Western Qin overlord is too cruel. He is using this kind of poisonous plan and is not afraid of being scolded by the people of the world. Now he is dead not only by the soldiers of the Tang army, but also by the people who are twice ashamed of the disease. The condition of this city cannot be controlled. If it becomes a cage, it will be buried here."

Fang Xuanling said: "It's not appropriate to go to the next young master to leave immediately and break out as soon as possible."

After pondering, Liu Hongji said, "Let's do this, Generals such as Murong Luohu, Li Anyuan and others are stationed here to resist the attack of the Western Qin army and drag their main force to pursue. You will lead people to break out and return to Jingzhao County first, and then send people to send the second young master back to Daxing City for treatment."

Fang Xuanling and Liu Jing nodded, thinking that this was safer. They could not be withdrawn all because the local Western Qin army was behind the scenes and could encircle and annihilate all the Tang army.

Now the Tang army has limited combat effectiveness, and most people cannot walk at all and can only stay here.

Liu Jing contacted Li Shimin's confidant military officers, Yin Kaishan, Duan Zhixuan, Zhao Ke, Lei Yongji, Zhang Gongjin and others, and selected eight thousand soldiers who were still in physical strength and did not get sick. He left the city in the middle of the night, fled, and retreated to Jingzhao County in the rear.

The scout of the Western Qin army discovered that a Tang army was withdrawn and captured the Tang army soldiers who fell behind. After learning about the situation in the city, he immediately reported it to him.

After Xue Ju learned about it, a smile appeared on the corner of his mouth and ordered the army to turn around and go back. The troops came to the city and seized the city like a bag.
