"Your Majesty, the only way to do this is to send additional reinforcements to Huya Mountain and Yuting. In such mountain wars, our army still lacks some experience. Now we can only defeat the Shu army in terms of military strength, so that we can have the chance to defeat the enemy." Du Yu proposed a plan to send additional reinforcements to Cao Liang.

Since the war started, four of the five battalions of the Right Legion have been invested, and only the Shooting Battalion stayed in Jiangling as a reserve team and did not participate in the battle. The battle situation on the front line is not good, and Du Yu can only think of only a new force.

Cao Liang shook his head gently and smiled faintly, "In this kind of mountain war, the number of troops is not a decisive factor. Whether it is the Qiting or Huya Mountain, the terrain is extremely dangerous. Even if the troops are increased, it may not be of much effect."

Du Yu said: "With your Majesty's opinion, what should we do?"

Cao Liang did not answer directly, but slowly walked to the middle of the cabin. The cabin where Cao Liang lived was very large, and there was a very wide table in the cabin. On the table was a huge sand table, which simulated the terrain of Xiling in equal proportions, which was very detailed.

Compared with maps, sand tables have the characteristics of a strong three-dimensional and intuitive image, which are easier to reflect the real situation on the battlefield. The only inconvenience is that they are not used for carrying and are not as small and light as maps. Therefore, the use of sand tables is relatively limited, and only the strategic command can be equipped with sand tables.

The sand table in front of Cao Liang was specially made for this battle of Xiling. It not only reproduces the complex terrain of Xiling in proportion, but also clearly marks the troops and offensive and defensive situations of the enemy and us. The situation on the entire battlefield is clear at a glance.

Cao Liang stood in front of the sand table, gently caressing his short beards, thinking about something.

Du Yu stood behind Cao Liang. Seeing Cao Liang pondering, he didn't dare to disturb him. He could only stand respectfully with his hands down.

After a while, Cao Liang looked back at Du Yu, pointed to the sand table and said to him: "Since Jiang Weilu is now fighting against heavy troops on the periphery of Xiling, the defense of Xiling City must be relatively empty. Why don't we come to him and take down Xiling directly? Yuan Kai, what do you think?"

Du Yu was stunned for a moment. Cao Liang's idea was somewhat beyond Du Yu's expectations. Logically speaking, the external defense lines such as Ma'anshan in the Qiting were to protect Xiling. How could they get down to Xiling without clearing these obstacles in the peripheral areas?

But looking at Cao Liang's confident expression, he looked completely confident, it was obvious that Cao Liang had already had a mature plan, so Du Yuyi said, "I am stupid and don't know what Your Majesty's brilliant plan is, and I hope to hear the saint's view."

Cao Liang smiled, is Du Yu really stupid? Of course not. If Du Yu had no ability and ability, would he still sit in the position of General of the Right Army's commander-in-chief?

But now their status has changed. In the past, Cao Liang was just a lord, while Du Yu was a subordinate. They fought side by side, and there was not much barrier. Especially in military affairs, Cao Liang adopted a relatively open-minded policy, and everyone spoke freely and was not conservative. There were even cases of questioning Cao Liang in person.

Now Cao Liang is the king and they are the ministers. There is a concept of superiority and inferiority between the king and the ministers. Even if Du Yu has his own ideas, it is difficult to speak out as bluntly as before.

Cao Liang could only smile bitterly inwardly. Indeed, as his status changed, they could no longer return to the intimate and uninterrupted relationship of mutual support. In this era, there was a natural gap between the monarch and the ministers. Even no matter how close the person was, he could not cross it.

In fact, this plan to directly attack Xiling has long been in Cao Liang's plan. Now that the frontal attack cannot be started, Cao Liang has already begun to consider finding a new offensive route.

In this battle of Xiling, Jiang Wei did not use the tactic of defending Xiling City when building the Xiling defense line. After all, Jiang Wei knew the ability of the Wei army to siege the city. No matter how strong the city defense of Xiling was, it would not be able to withstand the Wei army's catapult. Once the Wei army was allowed to come to the city, Xiling would definitely not be able to defend it.

That's why Jiang Wei used the usual methods of the Shu army and built a long encirclement on the outside line based on the dangerous terrain around Xiling, trying to intercept the Wei army on the periphery of Xiling.

At present, the outer defensive positions of the Shu army are mainly composed of Hushan and Ma'anshan, forming an arc-shaped defensive long encirclement, protecting Xiling City in the middle. No matter which direction the Wei army launched an attack, they must break through its outer positions before they can reach Xiling.

Now, a new offensive plan that Cao Liang considered was to bypass the outer defense line of Xiling and launch a direct attack on the hinterland of Xiling. As long as the Wei army could take down Xiling City, it would be like the center blossoming, and the Shu army's Xiling defense line would completely collapse.

Of course, this plan is an incredible thing in the eyes of others. After all, Jiang Wei carefully constructed the Xiling outer defense line, which was a targeted deployment. If Cao Liang really could lead his troops to bypass the Shu army's outer defense line and directly attack Xiling City, wouldn't Jiang Wei's defense line be useless?

In fact, although the defense line of the Shu army is tight enough, Xiling also has a fatal weakness, that is, it is on the verge of the Yangtze River. Now the Wei army's navy has controlled the Yangtze River's water control power, and the Wei army's warships can drive to the surface of the Xiling River.

Of course, in the eyes of many people, the control of waterways has nothing to do with the gains and losses of Xiling City. After all, the warships of the Wei army can sail to the Xiling River, and the Shu army cannot do anything to it. But in the same way, the city defense of Xiling City is strong, and the Wei army's navy also sighs at the city.

The Wei army controlled the Yangtze River waterway, and the most important significance was to isolate the possibility of the Shu army crossing the Yangtze River south, limiting their scope of activities to the north bank of the Yangtze River. As for whether Xiling City is safe, no one seems to be worried about this issue.

Cao Liang obviously would not give up such an opportunity. If the peripheral offense can make ideal progress, Cao Liang will of course adopt this step-by-step offensive method, which is the safest way.

But the current situation is that the Wei army failed to advance in the two routes of Qiting and Huyashan, and was unable to break the situation for a long time. If the force attack continues to be used, the Wei army will have to bear a greater cost of casualties, which is obviously something Cao Liang did not want to see.

Therefore, Cao Liang has been considering a new attack method, taking Xiling straight from the water, giving them a center to blossom, and completely destroying the enemy in Xiling.
