However, even the retreat is not so smooth. After all, large equipment such as catapult lathe crossbows are time-consuming and labor-intensive to deploy, and cannot be achieved overnight when retreating. Just like a single soldier, these bulky things will take a lot of time to retreat.

Just as Sima Jun was tiring up the catapult cart and mattresses and were preparing to move them beyond the range of the other catapult cart, the Bingzhou Army's stone bombs never stopped, especially when they saw the Sima Jun preparing to retreat, they fought more happily, and the launch frequency of the catapult carts further increased. The stone bombs continued to fall on Sima Jun's position, and several catapult carts and mattresses were destroyed.

Even if they can't smash the car, they can easily hit people. Sima Jun's catapult drivers are really hard. In order to ensure that these catapults are not destroyed, they risked their heads to snatch food from the tiger's mouth and rescued the remaining intact catapults and crossbows.

But it is really not easy to seize food from the tiger's mouth. At this time, the Bingzhou Army accelerated the frequency of attacks on stone casting cars, and more stone bombs flew in the air, and many Sima soldiers were buried under the attack of stone bombs.

The large number of casualties of the personnel also delayed the withdrawal of the catapult cart and the crossbow. When the Sima army was in a daze, many catapult carts and the crossbow were destroyed. The entire catapult carts ended with the failure of the Sima army.

It was exactly the same as yesterday. After the catapult attack failed, Sima Jun immediately turned into the ants attack.

The only way to destroy the two arrow towers in secret did not have much impact on the defense of Bingzhou Army. The most important thing is that Sima's stomping arrows failed to form an effective role. In other words, if Sima's army wants to attack the city, the only way for the cloud ladder is to rely on. However, because the Bingzhou Army continues to use tinder oil on a large scale, the damage rate of Sima's ladders is quite high. If Sima's army wants to maintain that kind of continuous offensive, it must have some guarantees on the equipment to climb the city.

However, today's attack seems to be a little smoother than yesterday. At least there is no need to spend a lot of manpower and time to fill the moat. From Sima Jun's camp to Jiexiu City, it is completely flat. Sima Jun only needs to focus on siege.

Moreover, after learning about the fact that Jiexiu had a urn city, Sima Jun gave up his plan to attack the city gate. He lost thousands of people yesterday, which undoubtedly became Sima Jun's deepest pain.

Originally, the weakest link in the city defense was the city gate. Once the city gate was lost and the enemy drove into the city, all efforts on the previous city wall would be vain.

Building such a urn city now means adding a defense to the weak part of the city, making the enemy's move to break through the city gate meaningless unless they can break through the two city gates in succession.

It is almost impossible to break through two city gates in a row under the current combat conditions. Not to mention that huge siege vehicles are difficult to pass through the narrow city gates. Even if they enter the urn and are attacked on three sides, this is probably something that no army can bear. Entering the urn is equivalent to entering the pocket formation of others. Yesterday's battle proves that the chance of surviving is zero.

Therefore, this method of siege was abandoned by the Sima army, and now only the most monotonous method of siege is left.

Sima Yi was no longer interested in continuing to watch the battle. Originally, Sima Yi was just disguised as a concealer to hide his identity. The command of the entire siege was still in the hands of Chen Qian and Sima Shi. Sima Yi was only making some suggestions at most.

Sima Yi had no need to stay in this simplest and crude ants attacking the city. He had fought for many years and had siege countless cities, so he naturally knew that it would be difficult to break through the city with ants attacking the city in two strokes. This way of siege itself was to use human resources to consume the opponent's defensive power, and constantly weaken the opponent during the process of increasing and deteriorating, and finally it was possible to take down the city.

This process can be as short as ten days and half a month, and as long as one or two years. Only through quantitative change can the effect of qualitative change be achieved. In the long process, Sima Yi naturally has no physical strength and energy to guard it, and can only be handed over to young people like Chen Qian, Sima Shi and others.

Chen Qian and Huaimashi worked very hard. They personally commanded the battle on the front line, urging the Sima army to continuously launch attacks, trying to find Jie Xiu's gap and open the door to victory.

But unfortunately, Jiexiu City's defense is almost impeccable. Even if Chen Qian and Sima Shi tried their best, they could not break through this solid line of defense. The entire Jiexiu city was filled with corpses like mountains and blood flowing into a river, but Chen Qian and Sima Shi were worried and could not find any effective way to break through the city.

Jiexiu's siege seemed to be in a deadlock. Originally, the Sima army planned to siege Jiexiu and attack the reinforcements after siege Jiexiu. It set up an ambush in the north of Jiexiu, preparing to severely damage the reinforcements of the Bingzhou Army.

However, Jiexiu City failed to defeat it repeatedly, and the Sima army could not pose any threat to others. Naturally, Jinyang did not send any reinforcements. As a result, Sima army's plan to ambush was ruined again. More than 100,000 troops were dragged under Jiexiu's city and could not advance or retreat. The entire battle situation also fell into a stagnant state.

Jiexiu is the only way to go north to Jinyang, but it is not the only way. In fact, if Sima Jun really wants to march into Jinyang, there are still multiple choices.

However, bypassing the break, there is a huge risk that cannot be ignored is that Sima Jun’s long supply line cannot be guaranteed. If everything goes well in the attack on Jinyang, if Jinyang can be won in the shortest time, there will be no problem with the battle situation.

But if the besiege of Jinyang is like the besiege of Jiexiu, and after falling into a long tug-of-war, Jiexiu, who is in the rear, will become the thorn of the Sima army, which will seriously affect the safety of the Sima army's supply line. Once Jiexiu's defenders attack and cut off the food route on which the Sima army relies for survival, then more than 100,000 troops will inevitably fall into the territory of the food shortage, causing disastrous consequences.

Such risks are obviously something that Sima Yi cannot bear. When he attacked Huainan last time, although Sima Yi used a long-term siege to Shouchun City, the transportation line from Luoyang to Huainan has always been unobstructed. Sima Yi had no worries and could let go and do whatever he wanted.

But the current situation is different. If you can't stand Jie Xiu, it means you can't open the door to attack Bingzhou. Sima Yi is really worried to solve this problem.
