The entrance to the underground fortifications is in a small and inconspicuous courtyard, and the large tiled house looks like no different from the rest, but in the middle of the room is a long staircase leading to the ground.

Li Mu instructed Yu Zihao to continue to lead people to search, while he, Boss Qian, and Chen Zhe took the first twenty elites, followed by the base that found the underground station, under the leadership of the old man, turned on the flashlight, and walked down the steps. After walking dozens of meters in one breath, it is estimated that the drop is more than ten meters away from the surface, and finally arrived in a spacious empty field. This empty field is more like a platform, with railroad tracks on one side and several passages on the other.

"According to legend, there is an underground city under the capital, which is an air-raid shelter facility established in the early days of the founding of the People's Republic of China, and the underground passage connects the entire capital together." Old man Yu said, "There is also a railway directly to the underground of Zhonghai, the leaders go out to inspect, when they don't take the plane, they all take the underground train directly, but who would have thought that this is true......"

"At least the railroad is real." Li Mu said with a smile, who can play with trains? Go up and see if the thing can still go. ”

None of the people in the group knew how to drive the train, but checking the condition of the train was not a problem. This train looks very old, it is not an electric railcar, but an old locomotive powered by an internal combustion engine, and the train is full of tanks of diesel, and there is even a fuel tank hanging from the rear of the train! In addition, the twelve-car train, two of which are loaded with various emergency supplies, including food, water, medicine, clothing, and even weapons.

It's a mobile haven of refuge.

"Commander, let's not worry about food now!" Old man Yu said excitedly.

"Well, I'll ship it all back later, and everyone will have more dinner tonight." Li Mu said with a smile.

In the midst of everyone's cheers, Li Mu's eyes looked at the other side of the passage.

The surprise came again, two of the passages connected to the two huge warehouses, which were piled with more war supplies, but the remaining two passages were blocked by huge iron gates, and through the observation holes on the iron gates, there were still underground corridors with endless lights, which seemed to be connected to the legendary dungeon.

"Let's go back and see how to open these two doors, and we can shuttle freely through the capital, haha......" Qian Lao Da said with a smile.

"That's a good idea, I'll leave this task to you, let's find out a map of the dungeon first, hehe." Li Mu said with a smile.

If the underground passage is available, turning around and then adding Zhonghai to the base is equivalent to having a fortress that can be attacked, retreated, and defended, and even if the Federation kills it in the future, it can disappear from the ground at any time, so that they can't find themselves......

But why run away? As long as the evidence is found, once the truth is released, where will the Federation still have the heart to clean up its own small base under pressure?

At that time, there are only two possibilities, one is that the Federation admits the mistake of decision-making, begins to change its position, and attacks the zombies in order to seek forgiveness and recognition from the survivors, then it is too late for them to woo themselves. The other is to be tough to the end and continue to carry out their screening plan, the result will inevitably be to lose all the hearts and minds of the people, so are they far from falling?

Li Mu was thinking about it, but he heard someone running down the stairs quickly, and before the person arrived, he shouted loudly: "Commander, it's not good, the Federation has killed ......"

Li Mu was startled, and immediately greeted him, and stopped the panting guy on the stairs, but it was a member of the combat team, and after asking again, he found out that the people of the Federation had been killed outside the Donghua Gate, and the chief of staff An Ran called Li Mu on the walkie-talkie, but because Li Mu went underground and couldn't get a signal, Yu Zihao sent someone down to inform him.

"Let's go!" Li Mu hurriedly ran towards the ground, while quickly analyzing, in the morning, An Ran also said that the federal's satellite phone called, and Qin Junming also reported that everything was normal, why did the people of the federation kill it in the afternoon?

Could it be that Qin Junming has something greasy on the phone? For example, the Federation was warned with a code or something?

But it doesn't matter anymore, the important thing is to rush back to support as soon as possible, and then push the Federation back first!

"Commander......" Yu Zihao saw the light coming up, and shouted in a hurry.

"Chen Zhe, Yu Zihao, you take some people to stay, go down and move some weapons and ammunition and bring them back." Li Mu commanded loudly as he walked, "The rest of the people follow me and kill those damn Federation lackeys!" ”

The crowd responded, either in a jeep or on foot, heading straight for the Forbidden City.

Returning to the palace from Xihua Gate, he heard the sound of gunfire in the direction of Donghua Gate, and the sound of bombs came from time to time, but Li Mu breathed a sigh of relief, the battle was not over, and the Federation had not yet attacked, and the most fortunate thing was that as he expected, the Federation obviously cared about the meaning of the Forbidden City, and did not use weapons of mass destruction such as missiles!

That means there's still a chance to fight back!

"Commander!" When An Ran saw Li Mu, he suddenly had a backbone and shouted.

"How's it going?" Li Mu asked, scanning the surrounding situation.

The city tower of Donghua Gate has been blown up by Li Mu with RGP-7, although the gate below the gatehouse has not been blown up, but the gatehouse is unavailable, and the difficulty of guarding has increased a lot. At this time, Gao Wei was leading a small group of soldiers to reinforce the gatehouse guards, and more than 100 people were hiding on this section of the city wall, constantly shooting downward, and there were bullets below that broke the city bricks on the women's wall.

"There is a lot of fire outside, it is estimated that there are two or three hundred people, and there are two armored vehicles." An Ran said, "It should be that the armored vehicles have only fired at the city gate and city wall a few times so far, it should be that the armored vehicles have only fired at the city gate and city wall......"

Li Mu listened while running towards the stairs next to the city gate, the strengthened physique, a few steps quickly jumped to the city wall, bent down to the edge of the female wall, but An Ran, who followed closely, immediately handed Li Mu a small mirror, and officially brought the "goods" that Li Mu brought when he first crossed over.

Smiling slightly, taking the mirror, Li Mu carefully leaned out of the mirror to observe the situation outside. However, I saw that some houses on the other side of the moat flickered from time to time, but it was the people from the other side who climbed on the roof to shoot. But the road facing the Donghua Gate was foggy, and I didn't see the two armored cars An Ran said, but suddenly a huge fire flickered, followed by a shock to the city wall, and a ball of fire came out under the city gate next to Li Mu, and then a crack appeared in the city bricks under his feet, and the city wall was swaying and obviously about to collapse.

Li Mu immediately activated the active slow motion, flew towards An Ran, and fell to the other side of the crack with her, and then the city wall roared loudly, and the Donghua Gate completely collapsed......
