The weather gradually became hot, but Jiexiu's battle situation showed no sign of improvement. The number of casualties was increasing day by day. Chen Qian and Sima Shi added a task every day, which was to bury the bodies of the fallen soldiers.

After the weather became hot, these remains could no longer be preserved. In order to prevent the plague, they had to bury the dead bodies that day overnight.

But despite this, there have been many cases of diarrhea and vomiting in the army. Chen Qian and Sima Shi had to be careful to prevent the spread of the epidemic.

Due to the hot and dry weather, there has been no precipitation for more than a month. The drinking water of more than 100,000 troops basically depends on the Fen River, the largest river in Bingzhou.

The upstream of the Fen River is completely under the control of the Bingzhou Army. If the Bingzhou Army poisons or throws some cattle and sheep that have died of the disease in the upstream, the entire river will be polluted, and the possibility of a plague in the Sima Army will be greatly increased.

This is a must for Sima Yi, who is familiar with military affairs, but the key is how to prevent it. If the Bingzhou Army really wants to poison it, any river channel of hundreds of miles can be taken, and the Sima Army is unpredictable.

Once there is a problem with the river water, the drinking water of more than 100,000 troops will inevitably become an unsolvable problem. People can not eat for a few days, but they cannot not drink water for a few days. Especially in this hot and dry weather, lack of water will cause a fatal disaster.

Sima Yi was certainly unwilling to withdraw his troops. He carefully prepared for a year and mobilized a large number of troops to fight for the Northern Expedition, which ended in a sloppy manner because of the capture of Jiexiu City. Sima Yi could not accept it anyway.

What's more, Sima Yi had already felt the strangeness of his body, which was irreversible aging. Sima Yi had never felt as powerless as he is now. Sima Yi was originally a person with strong control, but now he felt that everything was gradually out of his control and could no longer do whatever he wanted as before.

Maybe he had already felt that the King of Hell was waving to him, and there was really not much time left for him.

Time is not waiting for me! If Sima Yi was ten years younger, he might have a deeper plan and more comprehensive and detailed plan, so that he could restrain and endure it. But he was over 70 years old and he really felt that he was unable to do it. He had no time to deal with it calmly. Faced with a difficult battle, he had to make a decision.

If Bingzhou is a lock, then Jie Xiu is the key to opening the lock. Sima Yi knew this, and Cao Liang understood it even more. That's why Cao Liang used the past few years to build Jie Xiu City from an unknown second-class small county into a solid fortress city.

He has been attacking continuously for more than a month. Sima Jun has paid a considerable price, but he has never made any progress. Jiexiu's city wall is almost a desperate existence. Sima Yi has fought for so many years and has never encountered such a difficult tough trick. Even if he uses all his solutions, it will be useless.

In helplessness, Chen Qian used the extremely laborious way of siege in the city, which was a pity that the Bingzhou army had already been on guard. The Sima army spent all his efforts to dig the tunnel to Jiexiu's city. As a result, the Bingzhou army drowned hundreds of people in the tunnel, and the plan to dig the tunnel eventually failed.

As for building Tushan and setting up Gaolu, Chen Qian has not tried it, but in front of the invincible catapult of the Bingzhou Army, such fortifications have no chance at all. As long as it is within the range of the catapult, it will be swept away, and even there is no counterattack power.

As for the range, it is naturally useless. The catapult is already the longest-range attack weapon. Its coverage is beyond the reach of other long-range weapons. Therefore, the existence of the catapult is the enemy of the Sima Army. Chen Qian and Sima Shi were so angry that his teeth were itchy, but he was helpless.

The Bingzhou Army protected the catapult car extremely tightly. These killer weapons were placed behind the city wall. The Sima Army under the city could only roughly judge the location of the catapult car from the flying stone bullets. So far, no one has been able to see the true appearance of the catapult car, let alone look for opportunities to destroy it.

Sima Yi didn't know how much food Jiexiu City had reserved, but from the current situation, it was inferred that the Bingzhou army had been holding on for more than one year without any pressure. Obviously, Sima Yi could not use the tricks against Wang Ling to deal with Jiexiu's enemy. After all, Jiexiu is just a small city on the border of Bingzhou. It is not like Shouchun, it is the capital of Huainan. Surrounding Shouchun is equivalent to pinching Wang Ling's lifeline.

The encirclement of Jiexiu had almost no effect on Cao Liang, but instead blocked the Sima army from the city, and the momentum of the offensive was repeatedly set. More than 100,000 troops were trapped here, and the food and grass consumption was extremely huge. Even Sima Yi was in more than ten states in the world, it would be difficult to sustain.

If the current strategic arrangement is not changed, Sima Jun's Bingzhou operation will only end in vain, consuming countless money and food, and losing countless troops. This result may be difficult for anyone to accept.

Sima Yi decided to take a risk to take a gamble, especially when information came, the main force of the Bingzhou Army's cavalry was discovered in the Qi County area, which made Sima Yi even more determined to fight.

In the last battle of Shangdang, Cao Liang completely gave up all the city strongholds and led his army to deal with the mountains and ridges of Shangdang. He used the cavalry's high-speed maneuverability to find opportunities to annihilate the enemy, severely attacking the Sima army.

So this time invading Bingzhou, Sima Yi deliberately expanded the cavalry team, wasting a lot of money and a year of waste to be considered as the cavalry being made into shape.

But in siege battles like Jiexiu, the cavalry team was completely unable to use their strength. Of course, Sima Yi was reluctant to let the cavalry abandon the horse for infantry battles. Therefore, since the Northern Expedition, the infantry team was the one who was really responsible for the main attack mission. The cavalry could only watch from the wall, and they were almost growing hair when they were idle.

But this is also a helpless move. After all, siege war is not the place for cavalry to use. The more important role of cavalry is that in field battles, Sima Yi built such a huge cavalry team to decide the outcome with the Bingzhou cavalry.

In fact, compared to Jiexiu City, the cavalry of Bingzhou Army was Sima Yi's real enemy. After finally mastering the movements of Bingzhou cavalry, Sima Yi decided to bypass Jiexiu, attack Qi County, and launch a decisive battle with Bingzhou Army. As long as the vital strength of the Bingzhou cavalry can be truly eliminated, the final victory of this war can be won.
