Sima Yi valued power and neglected technology. He devoted his life to intrigue and deceitful political power schemes. Sima Yi naturally disdained those "strange tricks and tricks". If it weren't for Sima's army's catapults to be completely defeated by the Bingzhou army this time, perhaps Sima Yi wouldn't have seriously considered what Ma Jun's inventions were used for.

People in this era are almost not interested in those novel inventions, especially those who are in power. They never seem to take these inventions seriously, let alone apply and promote them. Even Cao Rui, who appreciates Ma Jun, was very happy because Ma Jun created a hundred plays for him to enjoy. He had no support for Ma Jun's inventions that could truly improve the combat effectiveness of the army, so that many of Ma Jun's inventions were sealed in the old paper pile and were not expected to be published.

However, today's confrontation between the two armies made Sima Yi seem to understand something. It seems that he has really missed an opportunity. If Ma Jun could be reused, perhaps the situation on the battlefield today could be reversed.

This Cao Liang is really not an ordinary person. When he was in Luoyang, he had a good relationship with Ma Jun. Obviously, all the inventions and creations of Ma Jun during his lifetime fell into Cao Liang's hands. Could it be that he had already planned the current battle back then?

You know, this happened more than ten years ago. From this point of view, Cao Liang's scheming and cunning are far beyond the ordinary people.

The failure of the Battle of Lingshi Pass may be attributed to the result of Sima's army's light troops advancing. However, in the Battle of Jiexiu, the Sima army, who had been fully prepared, still had difficulty in winning. This made Sima Yi, who was full of confidence in this Northern Expedition to Bingzhou, a little shaken. Could it be that he is really old? Is it really impossible to even be able to defeat such a young junior?

Sima Yi has been carefully preparing for this Northern Expedition for more than a year. He is more attentive to Cao Liang than to target any opponent. It took Sima Yi much effort just to raise such an elite cavalry.

But before his cavalry came on the stage, the infantry as the vanguard battalion had already suffered defeats one after another, which made Sima Yi's journey covered with a thick layer of dust.

"Tomorrow, I will visit the Pioneer Camp in person. I want to see how difficult this Jiexiu City is!" Although Sima Yi learned about Jiexiu's situation from the constant official documents, he was still better than seeing him. He was going to visit Jiexiu City in person and look at him.

Sima Yi was willing to come to the army in person, which made Sima Shi relieved. Originally, the biggest purpose of his trip was to listen to Sima Yi's suggestions, how to effectively crack the defense of the Bingzhou Army and break through Jiexiu City.

But if Sima Yi could personally come to Jiexiu City, this would make Sima Shi much more worry-free. If Sima Yi was allowed to command the Pioneer Camp, the effect of the siege would definitely be hundreds of times stronger than that of Chen Qian and him. It would be very certain to take Jiexiu City as soon as possible.

However, the only thing that made Sima Shi a little worried was whether Sima Yi's body could bear it. After all, Sima Yi was over 70 years old, and his physical strength and energy were already much worse than before. Staying in the central army's tent to plan and go to the front line to command were two different things.

"It's so good, but the child is worried about whether his father's body can be eaten?" Sima Shi said with some concern.

Sima Yi smiled faintly and said, "It's okay, if you fight for your father for a lifetime, why don't you be afraid of the hardships of the battlefield? You have to see everything with your own eyes to see how Chou and Yin and Mao are coming."

Sima Shi said: "Wi, I will go and arrange it now."

Sima Yi waved his hand and said, "For my father, I don't have to make a statement when I go to the Pioneer Camp this time. I just observe and will not interfere with your command."

Sima Shi suddenly realized that it was true that Sima Yi was going to the Pioneer Camp to hide this time. In fact, it was true. After all, Sima Yi was the commander of the three armies, and the Pioneer Camp was at the forefront of fighting with the enemy, and the level of danger was the highest. If Sima Yi exposed his hiding, it would inevitably make the Bingzhou army take risks. Therefore, no matter what, Sima Yi could not be allowed to take risks. It would be better to go in a low-key manner.

Sima Yi then asked Sima Shi for some details. Although he had received a more detailed report, Sima Shi, as the deputy vanguard, experienced this battle personally. Sima Yi not only had to listen to his narrative, but also listen to his views. Failure is not terrible, but if he did not learn from failure, it would be a real failure.

Sima Shi did not dare to hide it at all, and explained the details of today's battle to Sima Yi in detail. Of course, he also told Sima Yi that the most important thing he returned to the base camp this time was to ask for support. In addition to the serious damage to the catapult car, the vanguard battalion also suffered a lot of damage to the ladder. If it could not be supplemented in time, the subsequent attack would be weak.

Sima Yi was slightly surprised. After all, the equipment and equipment of the Pioneer Battalion can be said to be the most excellent in the entire army. It is reasonable to lose the catapult to the Bingzhou Army. However, the consumption of cloud ladders is a bit too great. After only one day's battle, nearly half of the cloud ladders were damaged. If this is true, it would be a big problem to be the supply of cloud ladders.

"Father, this is how it is. The Bingzhou Army uses tiny oil to pour, so the damage to the ladder is quite severe. The craftsmen from the Pioneer Battalion have already built it overnight, but I'm afraid that there will not be so many overnight, so I asked my father to transfer some from the central army to solve the urgent problem."

Sima Yi frowned slightly, but he didn't say anything again this time. He knew very well that turmeric oil was not commonly used in the army, it was scarce and in short supply, and even if you have money, you might not be able to buy it. Cao Liang could actually prepare so much and be able to use it on such a large scale in the battle to defend the city. It's really rich!

Of course, Sima Yi would not refuse Sima's request for help. He immediately ordered the recruitment of all the catapults, siege cars, bed crossbows and a large number of ladders in the central army, and rushed to Jiexiu's front for reinforcements.

However, Sima Yi only mobilized material equipment to the front line, but did not reach the number of troops. Moreover, Sima's division had no requirements for military strength. After all, the Pioneer Battalion had as many as 50,000 people, which had an absolute advantage in terms of number. If you ask Sima Yi for reinforcements, wouldn't it make people laugh?

The vanguard battalion is not short of people, what is lacking is the weapons and equipment. As long as the ladder is in place, the Sima army's attack will surely set off a new climax tomorrow.
