Three days later, the Intelligence Department submitted a top-secret information to Ye Anfeng, a reference guide for anti-tunnel combat. This reference guide includes some known internal structural diagrams of combat fortresses, as well as the external landform characteristics of these fortresses, the distribution rules of magic traps, and the most important thing, the distribution map of Shangyang County tunnels.

The direction of the tunnel is marked in three colors. The blue part represents the identified tunnel, and the green part is the Intelligence Department. The intelligence analysis experts calculate the direction of the tunnel drawn by the intelligence analysis experts, which has a high credibility. The yellow part is the military engineering experts invited by the Intelligence Department. They are added based on their own experience, and the credibility remains to be examined.

After receiving this information, Ye Anfeng praised the Intelligence Department for praise. Although this information cannot fully present the full picture of the underground tunnel defense system of Shangyang County, Ye Anfeng still sent this information to the participating legions, allowing them to serve as an important reference for combat in Shangyang County. Also issued were the authentic combat regulations formulated by Chen Kingdom and Ye Anfeng's oral decree: "Combining reality, flexibly apply it, and perfecting the map."

After receiving the latest information, the legions significantly strengthened the offensive rhythm. The main forces of the three legions of Rising Sun, Fierce Tiger and Red Star all entered Shangyang County. They quickly cleared the outer positions of Changqing, Jinding and Tongluo, and the troops were at the city. The situation in Shangyang County suddenly became tense, and a war that determined the fate of both sides was about to begin.

With the anti-tunnel combat reference issued by the imperial court (Nanchen Kingdom), the three major legions were no longer able to do anything about the underground tunnels and fortress combat systems of the people of Chen Kingdom during the advancement. Whenever they encountered similar terrain mentioned in the combat reference, the various legions of the Nanchen Kingdom would stop voluntarily.

Perform fire reconnaissance on all suspicious targets.

Although doing so will not pose any threat to the underground tunnels of the Chen people, it can cause a major blow to the fortresses connecting them to the ground, and sometimes it can even directly destroy the fortresses of the Chen Kingdom. Doing so will, on the surface, waste a lot of magic shells, resulting in a decrease in the marching speed. But in fact, the chance of troops being attacked by the enemy during the marching is greatly reduced, the losses of personnel and materials are much smaller, and the marching speed is much faster.

Because Nanchen Kingdom mastered some methods to find and crack underground fortresses, the people of Chen Kingdom no longer dared to use underground tunnel systems to fight unscrupulously to prevent the personnel and materials entering the fortress from being consumed in vain.

After a month of tug-of-war, the three legions of Rising Sun, the Tiger and Red Star cleared the enemy's peripheral positions on their way forward. Rising Sun Legion arrived at Yuquan Peak outside Changqing City. The main force of the Rising Sun Legion was stationed in front of Xiaozhu Peak outside Jinding City, and the Red Star Legion was stalemate with the Chen Kingdom army in Sandaoyan outside Tongluo City. After that, it was stalemate with the main force of the Chen Kingdom army in these places. Both sides continued to test, but no one dared to kill easily.

As mentioned earlier, after more than half a year of construction and transformation of Chen Kingdom, the three cities of Tongluo, Changqing and Jinding have been transformed into military fortresses. The mountains, highlands, rivers and other special terrains around them have also been transformed into permanent defensive positions, and heavy troops have been stationed therein.

But all this is just superficial. What really makes Ye Anfeng feel a headache is the ubiquitous tunnels in Shangyang County and the large number of mobile troops hidden in it.

The best test for both sides of the war is the strangle battle between the scouts. In the large army,

When it is appropriate to be dispatched, both sides will send large numbers of scouts to the other side's front line for reconnaissance. When the scouts sent by both sides encounter, a fierce strangulation battle will occur. First, it is to prevent the enemy from obtaining information from their own side, and second, it is because only by eliminating the other side's scouts, the battlefield reconnaissance work can be effectively carried out.

When scouts are dispatched, in order to maintain high mobility, they usually only carry light weapons with them. Once they encounter each other, they can only fight with light weapons. Although the competition between light weapons is not as vigorous as heavy weapons such as magic cannons, the bloodiness in them is even more than that. Scouts often encounter them forever, because preventing the enemy from bringing their own intelligence back is as important as obtaining local intelligence.

Because large-scale military operations cannot be carried out for the time being, the defense lines of both sides are done without any leakage. In order to find out the flaws in the opponent's defense line, both sides sent a large number of scouts. The possibility of encounters between scouts and straightforward rises. On the outskirts of the three cities of Tongluo, Changqing and Jinding, dozens of battles broke out between scouts every day. The scouts on both sides fell in pools of blood every day, with more than a thousand scouts.

At the beginning, in order to avoid the intelligence of the tunnels and underground fortresses being discovered by the scouts, Chen Guo did not use the tunnels and underground fortresses to respond to its scouts. However, as the scouts strangulation battle deepened, the scouts of the Chen Guo Guo gradually became at a disadvantage and were suppressed and beaten by the scouts of the Nanchen Kingdom, and the losses increased significantly.
