The battle city is the last military fortress established by the underground people, originally prepared to station the main force, with the top family to attack the city of freedom on both sides, did not want to open his teeth to destroy the creature room, released countless monsters, causing the largest catastrophe in the history of the underground world, in order to resist the invasion of monsters, the Northern Military Region had to withdraw the three main divisions to the underground to guard the dungeon and communication lines.

Now the three main divisions add up to less than one division of the remnants, and a large number of recruits have to be recruited every day to send to the meat grinder on the front line, compared to the dangerous underground, there is also a choke point where the war is raging, the new first division is living more comfortably, Chi Haige also has his own small abacus, afraid that his troops will fill the meat grinder underground, so he has been grinding and waiting, until the situation is clear.

I have to say that Chi Haige is a smart person and very practical, and he almost accepted Gao Feng's request, and even took the initiative to ask Gao Feng to send henchmen to serve as the chief of staff and deputy division commander of the new First Division.

With the underground army as the core, the First Division of the Army has reorganized 20,000 scientific and technological armed forces, with 1,200 combat vehicles, 36 automatic artillery pieces, 680 unmanned attack planes, and 300 unmanned reconnaissance planes, in addition to 500 heavy locomotives, 800 fighters, and 1,100 logistical auxiliary vehicles.

After a toss and turn by the peak, instead of weakening its strength, Chi Haige has increased a lot, among which the unmanned attack aircraft and fighters have directly doubled, and a large amount of logistics has been sent to the battle city fortress without restrictions, making him happy and convinced of Gao Feng.

When the nine Split Mountain Garo and the twenty-three regretful army Garo were assembled in place, Gao Feng and Jiang Feng took five thousand prisoners and escorted hundreds of carts of supplies, and headed towards the southern wilderness.

In order to fulfill Zhuang Midie's wish, to meet with his subordinates as soon as possible, and to be able to see that the unreliable guy in the Maple Leaf Hill was intact, Gao Feng came to the battle city with the team, but as a result, Gao Feng looked at the place and almost died of depression, it turned out to be the place where the Black Claw tribe once stayed, Beilong Canyon.

The canyon has been built into a huge fortress locked by the iron dragon by the underground army, and the two mountains on the left and right are wrapped in thick armor, like two black peaks, and countless hidden fortresses hide deadly firepower, which can spray tens of millions of bullets at any time.

The huge steel gate is more than ten meters high, and there are twenty 100-millimeter rapid-fire guns on the left and right, which just blocks the only exit, in fact, the gate is only for foreign enemies, and the underground army does not need the gate, when the floating car floats into the defense system of countless anti-aircraft weapon components, it is found that there is an urn city without entrance and exit behind the iron gate, God knows how many lives it will take to fill thousands of square meters of space.

The canyon can be called a fortress, and the new 1st Division will naturally not build the main defense line on the mountain, adhering to the consistent style of the underground army, the two peaks are all hollowed out, reinforced by steel frames, and built into a permanent fortress that cannot be fallen.

Countless tunnels in the belly of the mountain extend in all directions, accommodating thirty or fifty thousand people without being too crowded, many of the rooms are secretly arranged forts, and at a critical juncture, they can rise up the mountain and fire deadly tongues of fire at the enemy, and the nine people who have the perception of the mountain change color, if the throat can have such a dense defense, such a complex tunnel system, even if they dismantle it for ten days and half a month, they don't want to take it.

Gao Feng was slightly surprised, Chi Haige was also quite proud, and gave Gao Feng a detailed explanation, through his explanation, Gao Feng already understood the other party's plan, this fortress was used for defense from beginning to end, and even considering that Bangyun Jialuo personally took action, there are isolation doors in many places, once Bangyun attacked the inside, the isolation door will be put down, and the overall blasting will be implemented, if Gao Feng sneaks in according to the way he breaks through the throat, I am afraid that even if he succeeds, he will be buried in the ground by countless tons of sediment and steel,

"The ultimate combat goal of the battle city is to collapse the clouds and garo, every qiē is a trap, and the first division is the bait ......."

After Gao Feng and Chi Hai Ge came to the most hidden headquarters, Chi Hai Ge confessed to Gao Feng, and Gao Feng was already surprised, shook his head with a wry smile and said:

"Fortunately, I asked Jiang to come over to take a look at the situation, if I really want to capture here, I am afraid that the price to pay is several times greater than the throat ......."

"From the time Huang Shujie served as the garrison officer of the choke point, I knew that if I encountered the same, or even a slightly weaker army, I could be defeated, Huang Shujie is not a well-guarded officer, if you are Lianchengxue, you may not be able to attack ......."

Chi Haige's outspokenness made Gao Feng a little surprised, it seems that his plan is not bad, decapitation tactics are the essence of special warfare, if he hadn't killed Huang Shujie, how could he have won such a brilliant victory? With Chi Haige's analysis and explanation of the battle in the throat road, Gao Feng's face changed in a new way, from serious to strict, and finally his face was slightly pale.

"Huang Shujie should lead the special combat team to attack at the first time of attack, and should not stay at the headquarters to coordinate and command, the new 3rd Division and the 2nd Division are miscellaneous troops, except for their direct commanders, skipping the command will only add to the chaos .......

The new editors have a crack aura that they use to deal with the high-level Gara, but they have not used it from beginning to end, and if they make up their minds to attack irregularly in the direction of the line of fire, they can completely cause a regional ceasefire, so that they have time to organize the ...... of the team.

Lian Chengxue's premature departure is a fatal injury, as an old officer who survived the Third Ground War, I should not make such a mistake, if I were Lian Chengxue, I would not have accepted the wounded in the first place, because Jia Luo has too many means to sneak into the ...... while the chaos is in chaos.

The most unsuccessful area is the core fortress, even if the headquarters is breached, the core fortress can still function, as long as you hold on until dawn, you can recover from the chaos, and then the troops will spontaneously support the core fortress, thus initiating the final plan ....... ”

Although there is a suspicion of hindsight, Gao Feng thinks that what the other party said is right, he can achieve victory, and the element of luck is very large, if Maple Leaf Garo does not perceive immunity, if the underground army does not have a light enemy, concentrate on defense, if Nirvana Rift Mountain can be dispatched at the first time when attacked, it will cause the premature death of the attack, and it will also make Gao Feng's plan completely fail.

Dozens of unmanned reconnaissance planes are scattered throughout the southern wilderness, searching for suspicious movements all the time, but they have not crossed a single step beyond the Desperate Fortress, which was once abandoned and repaired, and hundreds of ancient spider robots patrol back and forth on the cliffs of the Desperate Fortress, and occasionally you can see a team of pit vipers on their backs. The armed men of the guns looked out into the wilderness.

The detected qiē has been fed back to the battle city, and the mechanical spider is the trophy of the Yuetan family hidden in the depths of the fortress of despair, and has achieved brilliant results, but the pit viper step. The appearance of guns is not normal, which means that the Goddess of Aurora has been connected to the Free City.

The predecessor of the City of Freedom is Willow City, which has been attacked by the city-state of Mochizuki and the goddess of dawn, with tens of thousands of dead and wounded, but I didn't expect to turn around, the goddess of dawn hooked up with the city of freedom, if the aborigines of the city of freedom knew, would it be angry and violent. Disorderly?

"Unmanned reconnaissance aircraft can only cruise in the inner part of the wilderness, and once they break through the fortress of despair, they will be shot down by airships, but fortunately, airships do not dare to come, and our equipment is not vegetarian ......."

In the intelligence information center, Chi Haige accompanied Gao Feng to check the intelligence collected by the first division for several months, but Gao Feng's mind was on the Goddess of Dawn, breaking through the choke point, which means that the wilderness has changed hands, and the Goddess of Dawn, who was suppressed by the underground army, should not be silent, why has no one contacted him, and what is the Goddess of Dawn hiding in the shadows calculating?

"By the way, I still have hundreds of miners here, they may be your former subordinates, do you want to meet ......."

Something suddenly came to mind. Chi Hai Pavilion said the news that surprised Gao Feng.
