With the technology of Xinghai World, the maximum speed on the ground can reach thousands of kilometers per hour, but that is a fully enclosed rail transit.
On ordinary highways, too high a speed can easily cause a car accident, even with autonomous driving.
After all, vehicles may break down while driving, so considering driving safety, the speed limit is generally within 300 kilometers.
The vehicle Jiang Yuanliu and the others were riding this time was a large military personnel carrier, more than 20 meters long, and each vehicle could seat fifty people.
This kind of heavy personnel carrier is slower than ordinary vehicles, with a speed of about 230 kilometers per hour. Excluding the time for rest and communication along the way, it takes about fifteen hours to reach Changling Pass.
However, this large troop carrier has an advantage. It drives very smoothly, so Jiang Yuanliu and the others can sit down and talk easily.
Sun Chengyuan asked Li Ye to sit down together, then took out a military quantum brain, clicked on it, and projected a three-dimensional map of Changling Pass, introducing the situation.
"This is the topographic map of Changling Mountain Pass. The authenticity is almost 100%. I have been to the area of Changling Mountain Pass. The terrain is indeed very dangerous. It is said that in order to build the D13 highway through Changling Mountain, The government has invested hundreds of billions of federal credits. "
"In fact, with current technology, there is no problem in digging a tunnel through the Changling Mountains. It is precisely to protect the logistics base in the southwest mountainous area. Instead, they built a road across the mountains and built Changling Pass at Changling Pass." Jiang Yuanliu took a closer look and found that Changling Pass was composed of two steep peaks. In the mountain pass between them, Changling Pass is built at the top of the mountain pass and is connected to the peaks on both sides. Highway D13 passes through the middle of Changling Pass.
Since there are cliffs hundreds of meters high on the north side of the two peaks, which are completely impassable, Changling Pass has become the only passage between the north and the south. Controlling Changling Pass means controlling A north-south passage covering thousands of kilometers from east to west.
Sun Chengyuan continued: "There is currently a regiment garrisoned at Changling Pass, numbered as the 1112th Regiment of the Donglan Front Army."
"This regiment is a mixed regiment. There are more than 3,000 people in total, including four battalions, two infantry battalions, an exoskeleton armor battalion and an artillery battalion. In addition, there is a biological armor company directly under the regiment headquarters."
"One by one. Xia Houzhong, the commander of the second regiment, is a sixth-level Yuanli division with the rank of colonel. He has a calm and solid temperament and is good at defense. He is considered a strong general among regiment-level officers."
"Because of the scope of Changling Pass. There are only two special armor companies and one infantry company stationed in Guan Guan. One of the two special armor companies is an exoskeleton armor company and one is a biological armor company. The other troops are stationed in Guannan."
"The terrain in Guannan is slightly flatter, and a group of fortresses have been built to accommodateFour battalions of troops.
Jiang Yuanliu pointed to the cliffs on both sides: "Can cultivators climb over the Changling Mountains from these cliffs?" ”
“Low-level cultivators can’t do it. At least a cultivator of level six or above can do it.” "
Sun Chengyuan shook his head: "But it's useless to climb up the mountain. The stone walls from the top of the peaks on both sides to Changling Pass are also very steep. If the cultivators airborne from the peak to the pass, they will definitely face serious difficulties. The double blow of artillery fire and cultivators made it impossible to land successfully. "
"As for landing from the top of the mountain to the south, you will also face a double blow from the fortress group, which is equally difficult. "
Jiang Yuanliu raised his eyebrows: "That means the enemy can only sneak attack Changling Pass, but as long as we are prepared and the defense force is strong enough, it is almost impossible for the enemy to capture Changling Pass. "
Sun Chengyuan agreed with his statement: "It can be said that unless someone destroys it from within, isn't there an old saying? ‘Fortresses are always easiest to breach from within’. "

"Yes, a fortress is always easiest to break from the inside! "
Jiang Yuanliu thought for a moment and asked tentatively: "You think, if the enemy really successfully attacked Changling Pass, what would they do? "
Sun Chengyuan looked stunned: "Did the enemy successfully attack Changling Pass? Your joke is not funny! "
Jiang Yuanliu's eyes flashed with light: "Let's just pretend, it's not true. Brother Sun, just imagine it. "
Sun Chengyuan thought for a while and said: "First, they will be well prepared for defense to prevent our Guannan team from counterattacking. "
"Second, they will try their best to destroy the heavy weapons at the gate, so even if we succeed in counterattack, the defense capability of Changling Pass will be greatly reduced in a short period of time. "
Jiang Yuanliu then asked: "So from Brother Sun's point of view, how long will it take for our counterattack to be successful? "
"If we add the existing defense forces to the newly formed special armor teams from Shangjiang, Longjiang and other cities, it will take an estimated four to five hours. "
Sun Chengyuan pondered: "After all, in order not to damage Guancheng, we cannot use heavy weapons. We can only attack closely and risk human lives. We fight for every inch and it will be difficult to capture it in a short time. "
Jiang Yuanliu asked again: "What if we have a special armored force launching an attack inside Guancheng? "
"It depends on the strength of that special armored force. If the strength is equal to or just slightly weaker than the enemy's sneak attack force, then the counterattack will be successful quickly. "
At this point, Sun Chengyuan seemed to have reacted and asked him: "But since the enemy has successfully attacked, how can we still have such a force inside Guancheng? "
Jiang Yuanliu did not explain, but said directly: "I remember that Guancheng like this usually has secret rooms to store important supplies., is there such a secret room in Changling Pass? "
Sun Chengyuan's eyes widened, and he seemed to gradually understand Jiang Yuanliu's intention, with a solemn expression: "You are right, there is indeed such a secret room in Changling Pass, which is used to hide important weapons and weapons. Personnel, do you plan to annihilate the enemy's sneak attack troops in the pass? "
Jiang Yuanliu nodded, then shook his head: "Brother Sun, how strong is Changling Pass, and what level of attack can it withstand? ”
“Can withstand attacks from mid-level Saint Masters!” "
Sun Chengyuan showed a confident expression on his face: "The purpose of building Changling Pass is mainly to prevent attacks from the north. Because the mountains in the north are undulating and the roads are not straight, energy weapons are almost impossible to use. This also determines that the main target of Changling Pass defense is physical attacks. ”
“Changling Pass used the most advanced materials at the time when it was first built. Later, it was repaired and reinforced several times, and the most advanced materials at the time were used each time. ”
“For example, the most recent maintenance and reinforcement was carried out ten years ago, and the steel used was the most advanced 385-phase naval alloy steel of this generation. ”
“So the defense capability of Changling Pass is very strong, and the S-class Saint Master can only damage it to a certain extent in a short period of time, but cannot completely destroy it.” "
Jiang Yuanliu seemed to be relieved: "That's it, then I'll be relieved. Last question, Brother Sun, if the enemy succeeds in a sneak attack and wants to permanently occupy Guancheng, how many troops will they need at least? ”
