While expanding the army and preparing for war, Sima Yi was also paying close attention to the trends of Bingzhou. Intelligence work is also extremely important for Sima Yi. Sima Yi has relatively complete intelligence networks in places like Guanlong, Jingzhou and Huainan. Relatively speaking, the intelligence system of Bingzhou is relatively weak, but it has also actively deployed in recent years, and the infiltration of Bingzhou has also achieved considerable results.

Sima Shi has always been responsible for the intelligence system in Bingzhou. He promptly fed back all the information he collected to Sima Yi so that Sima Yi could make reasonable judgments on the situation in Bingzhou.

Now the strategic focus of Sima Army has shifted to Bingzhou, so mastering the trends of Bingzhou Army is very important for Sima Army. Only by knowing oneself and the enemy can one never be defeated in a hundred battles.

What Sima Yi was most concerned about was the movements of the Bingzhou cavalry. This time, his large-scale expansion of cavalry was to use Bingzhou cavalry as an imaginary enemy. In Sima Yi's view, as long as he could defeat the Bingzhou cavalry, it would be like breaking Cao Liang's pair of wings, and the rest were not worth worrying about.

"Father, according to the latest information, Cao Liang transferred the Xiaoqi Camp, Yueqi Camp and Tunqi Camp to the valley and carried out training there. The surroundings were very cautious, so it was difficult for our people to approach and infiltrate, so they could only listen to the news on the outside." After Sima Shi received the latest information about the Bingzhou cavalry, he would often report to Sima Yi as soon as possible.

"Oh, that's right." Sima Yi said lightly and fell into deep thought. Now the two sides are fighting each other in a distance, fighting wits and strength. Sima Yi expanded the cavalry on a large scale, but it couldn't hide it from Cao Liang's eyes and ears. After Cao Liang received the news, he would inevitably have targeted strategic arrangements.

But what does it mean to drill into the ravine to practice? Could it be that Cao Liang will have new tactical arrangements that will not be told?

However, the cavalry's fighting tactics are now very mature. Even if Cao Liang asked the Bingzhou cavalry to practice a new battle formation, there was nothing new. In the final analysis, increasing the number of cavalry is the key to improving the combat effectiveness of cavalry.

"Cao Liang has acted to increase troops and increase war horses?" Sima Yi asked.

Sima Shi shook his head and said, "I haven't noticed it yet. Following his father's instructions, the child has sent people to lurk near the Bingzhou Cavalry Battalion to monitor it day and night. Although they cannot penetrate into the Bingzhou Cavalry Camp, they still know the situation outside. If Cao Liang transfers people and horses into the camp, he will definitely not be able to escape surveillance."

Sima Yi nodded, satisfied with Sima Yi's approach. What he is more worried about now is that Cao Liang will follow his example and expand the cavalry on a large scale. If Cao Liang spared no effort to do anything, Sima Yi's advantage would be gone and he would be busy for a long time.

However, judging from the current situation, Cao Liang did not intend to expand the cavalry, but it was normal. After all, it would be a luxury to support 30,000 cavalry with the financial and manpower of a state. If Cao Liang increases the number of cavalry, the first thing to be dragged down would be Bingzhou's economy. I believe Cao Liang knew this.

Cao Liang would definitely not be able to play such an arms race. Maybe Cao Liang hid the cavalry in the valley and conducted new tactical exercises, but no matter how much the exercises were, the cavalry was still a cavalry, and the combat methods were the same. No matter how Cao Liang tried, he would not be able to play.

On the battlefield, we have to rely on our strength to speak. As long as the Sima army has the power to crush the Bingzhou cavalry, Sima Yi believes that Cao Liang will not be able to defeat the world.

Sima continued: "However, the latest information shows that Cao Liang transported a large amount of supplies to the three cavalry battalions' garages, all of which were transported by baggage trucks, and they were covered tightly, and they couldn't figure out what it was."

"A lot of supplies?" Sima Yi frowned. Generally speaking, if food and grass are transported to replenish these supplies, there is no need to cover them tightly. If the coverage is really tight, it means that there are some unknown things hidden on these supplies.

Is it a weapon or equipment?

Sima Yi was also very clear that in order to improve the combat effectiveness of the cavalry, Cao Liang spared no effort. Yueqi Camp and Tunqi Camp are the second of the Five Northern Army Schools. You should know that the Five Northern Army Schools are famous for their bad army and have no combat effectiveness at all. The Overlord Cavalry Camp is the elite of the central army and has always maintained the fine tradition of the Tiger and Leopard Cavalry.

But it is precisely such an army that cannot be supported by the mud, which has shone new brilliance in Cao Liang's hands. Yueqi Camp and Tunqi Camp have grown into an elite army after repeated practical training over the years.

The reason why Sima Yi expanded the cavalry organization at all costs was precisely because of his fear of the Bingzhou cavalry. It was not easy for the Bingzhou army to defeat them.

Since Cao Liang has the means to turn decay into magic, Sima Yi will not take any actions of Cao Liang lightly. This time, Cao Liang transferred all the cavalry to the ravine for training, which is an unusual thing in itself, and the strict vigilance adds a lot of mystery.

Sima Yi, who had always been cautious, was very concerned about Cao Liang's abnormal behavior and said to Sima Shi: "If you try your best to penetrate into the camps of the Bingzhou cavalry, you must figure out what Cao Liang is doing. This decisive battle is related to whether the great cause of our Sima family can survive. No leakage can be made."

"Abide by my father's order!" Sima Shi received the order with a stern look. Sima Yi has always been aware of things, and Sima Shi would not suspect that he had made some big fuss. In short, be careful not to make a big mistake, and it is also very important to understand Cao Liang's true intentions.

However, the Bingzhou Cavalry Battalion was extremely strict in its garrison. It was indeed quite laborious to send people from the Bingzhou to infiltrate the cavalry battalion.

After Sima Shi retreated, he returned to his residence and ordered his subordinates to invite Du Feng.

Du Feng is the leader of the intelligence system under Sima Shi. He is skilled in martial arts and has both wisdom and courage. He is highly valued by Sima Shi. Now the intelligence personnel of Sima Jun cannot open up the situation in Bingzhou, so Sima Shi had to send Du Feng to personally investigate the reality of the Bingzhou Army.

Sima Shi explained Sima Yi’s requirements to Du Feng, that is, he must understand the real situation of the Bingzhou cavalry. Sima Shi hopes that after Du Feng arrives in Bingzhou, he will obtain this information at all costs. He will also receive the support of the entire Bingzhou lurking intelligence system to cooperate with him in completing this mission.

Du Feng bowed his order and set off overnight, leading his team to Bingzhou.
