Chen Yuan returned to the forest and continued to command his men to cut wood, he had already expected that the red side would use the superiority in strength to capture his own city in one fell swoop. But with only 5,000 troops in his hands, it was really not enough to resist such a powerful offensive. Therefore, Chen Yuan took out the empty city plan of the master of the art of war in Chinese history, known as Wolong Zhuge Kongming, to deal with the situation in front of him. "The Art of War" says: "A soldier is also a trick." "Truth and falsehood, fiction and reality, are ever-changing. But the result was as Chen Yuan expected, this empty plan shocked the 30,000 army and bought some time for himself to prepare.

This first step Chen Yuan is already considered to be stable, and the next step is the main event. After all, the question of this double test is not to be stubborn, but to capture the red city within three days. Therefore, in these three days, Chen Yuan must find a way to retain his own forces to the greatest extent while weakening the strength of the red side as much as possible.

So Chen Yuan gave the second order - to repair the bridge. He sent 800 earth knights and 800 engineers to the banks of the Jiehe River, began to measure the width and depth of the river, and began to transport the processed timber from the city to the riverbank.

As for why it was processed, it was because in order to simulate this battle to the highest level, there were woodworking and blacksmith shops in the city. As long as you transport the raw materials and pay a certain fee, you can process any material and create the weapon you want. Of course, this so-called cost can also be replaced by resources, such as wood, a resource, processing fifty trees, you need to pay one tree as the processing fee.

From Chen Yuan's order to start logging, to the attack of the Red Army, and now to the order to repair the bridge, five hours have passed, and within these five hours, Chen Yuan already has the resources of tens of thousands of trees, from small wooden wedges to large wooden stakes, all kinds of wooden raw materials. Resources are especially important in a campaign, and as long as resources are available, the army is hardly afraid of being consumed. Those who get resources win the world, Chen Yuan, who has experienced the baptism of modern warfare, firmly remembers this sentence, which is also an important reason why he chose the blue side as a base without hesitation. (For the sake of calculation and viewing, a tree is defined as a resource, and the resource is used as a unit)

Again, Chen Yuan's task in this assessment is not to hold on, but to capture the city, which means that the advantage of the terrain is not important on his side, he has no intention of guarding his own one-third of an acre at all, he wants to accumulate enough resources, fight out, and fight on the enemy's territory.

In this way, the more complex the terrain the enemy has, the better, and the complex terrain is conducive to small groups of troops to fight, because a small number of people also means high flexibility, easy to hide, and a high degree of use of complex terrain. Conversely, a large number of people means that the target is large, bloated, and easy to spot. Under the elimination of the other's strengths, the lack of troops on Chenyuan's side has become a big advantage.

The blue side in the east not only has a large area of dense forests that can be used as a strategic resource, but also has a single terrain, mainly plains, which is only suitable for frontal combat. The red side to the west has a complex terrain, with hills, mountains, lakes and swamps, which are all kinds of terrain, which is very suitable for ambushes and wandering. According to Chen Yuan's idea, what is the matter with fighting in front of his own house? If you want to do something, of course, you have to go to the enemy's lair to do something. Therefore, Chen Yuan did not hesitate to choose the blue side as the base area, firmly held the resources in his hands, and at the same time honestly and unceremoniously made the area of the red side a battlefield.

On the other side, while retreating to the city and replenishing supplies, the red side sent three hundred sky knights to patrol the territory and border the territory, and also spy on the blue side's movements. When he found out that the blue side was building the bridge, the red leader, the red general, suddenly felt that the boundary river was more than ten meters wide, and the depth was unknown, but the water flow was relatively turbulent.

The red generals took it for granted that the blue side chose to build the bridge in order to better complete the task, after all, to fight a battle, it was necessary to transport a large amount of baggage and grain and grass to ensure that the soldiers had sufficient combat effectiveness. Unlike the red side, which can directly launch a surprise attack with light equipment by virtue of its superiority in strength. The blue side has few troops, and the siege must be a very time-consuming tug-of-war for the blue side.

After the first unsuccessful attack, the red general obviously changed his strategy, the territory of the blue side was too empty, and the mighty army of the red side could not hide its tracks at all, but he did not know whether the blue side had set a trap and ambush in the city, so he did not dare to enter the city at all. However, according to the assessment rules, the blue side needs to capture its own city within three days, so the red general simply gathered his 50,000 soldiers in the city and directly defended the city. In this way, with the topographical advantage of the city wall, as well as the already superior forces, the defense of the city is nine out of ten. As long as nothing goes wrong, it would be foolish for the blue side to attack their own city within three days.

Moreover, it is difficult to build a bridge in the turbulent river, even if there are many engineers on the blue side, it is not possible to repair it in a while, to build a bridge that spans more than ten meters, it will take about two days to say the least, and the blue side of the red will waste all the time to repair the bridge and pave the road, so that it is even more impossible to break through their own city in just one day.

But is the truth really as simple as the red general thinks? Of course, the answer is no, Chen Yuan, who has military capabilities beyond this world, can't think of this? In fact, among the timber transported by a thousand infantry, in addition to being used as raw materials for building bridges, there are also some mysterious weapons and materials that have been completed. The weapons and supplies were transported to the riverbank and hidden in the Red territory.

Because many of the blue side's troops are gathered on the riverbank, of course the red side will send people to keep an eye on them, and the best choice is the Sky Knight, but the eagle dove always has a time when the eagle dove is tired, and then the red side will change the guard, and the gap between the change of guards, this batch of weapons and supplies will smoothly enter the territory of the red side.

As time passed, the rudiments of the bridge slowly appeared, and the amount of supplies secretly sent to the Red territory increased. Counting the time of the red side's surprise attack in the morning, a day has passed, of which Chen Yuan only quit the chessboard halfway and ate two meals, and has been deploying troops the rest of the time. On the surface, it is speeding up the progress of repairing the bridge, but in fact, most of the troops in the city are being transferred to the banks of the Jiehe River, intentionally or unintentionally.

A day and a half later, a wooden bridge appeared over the Jiehe River. After a shift change of the Red Sentinel, the Red suddenly found that the bridge had been burned down, and the Blue soldiers who had been on both sides of the river were completely gone. When the news reached the Red General, the Red General realized that something was wrong and immediately ordered all the Sky Knights to patrol their territory. However, even the Sky Knight takes some time to patrol the territory, let alone send the news back to the city. By the time the news reached the Red General's ears, it was too late, and the Blue 5,000 soldiers had completely occupied the mountainous terrain north of the Red City. And it seems that there is plenty of grain and grass for the baggage, and it is not at all like a hasty passage.

At this time, the red general realized that the huge bridge repair was simply a cover to cover up the fact that the blue side secretly transferred supplies to their own territory. I have to say that Chen Yuan's hand is also a beautiful play, in this way, Chen Yuan's army is like a nail, inserted into the most uncomfortable place of the red side, if you don't want to solve it, the red side wants to have a peaceful birthday.
