Hundreds of kilometers away from the holy city, there is a military camp surrounded by mountains.

The first army group, the most elite of the federal government, was stationed here. Every mountain around it was hollowed out and built into a fortress.

In the middle of the garrison camp, there is an all metal house built against a mountain.

The whole house is made of Taiheng alloy, which is very strong. There is nothing in the house, but a passage to the ground.

Following the elevator, two thousand meters below the ground, is the space agency headquarters of Shengxing.

As the most powerful and important defense base of Shengxing, the defense here can be described as an iron wall. Even the nuclear bomb can't damage the fortress 2000 meters underground.

At this time, in a room of NASA, fan Shiwen and Yan shengtu are concentrating on the picture.

Around them stood General Xu Bai, deputy commander of the Federal Space Forces, who was in charge of the war.

NASA is under the administration of the presidential palace in peacetime and the space forces command in wartime.

Now Xu Bai is the commander here.

"General Xu, can you live on the top of the holy star with so many warships?" Fan Shiwen asked in a low voice.

Xu Bai said quietly: "let's put it this way. As long as NASA is here, Shengxing will be OK."

Yan Shengguo glanced at him slightly, as if he didn't believe it.

Xu Bai said faintly: "there is a defensive array of Jiang Shen on the periphery of Shengxing. At that time, he was an Immortal King. He had the power to pick up the stars and get the moon. If it wasn't for the time, he could have done better."

"Without the authorization of NASA, let alone the warships of the three academies, even the fairyland immortals can't get into the holy star, so they are very safe. If they stay outside for a period of time and can't get in, they will naturally withdraw."

Fan Shiwen nodded his head when he heard the speech, which was a little reassuring.

"I'm not afraid outside. What if someone inside comes in?" Yan shengtu said.

"Ha ha." Xu Bai laughed: "who can attack?"

"Professor Gu, show them the plan of our underground fortress." Xu Bai said triumphantly to a NASA official nearby.

That person presses computer hastily, brush brush, a picture appears on computer.

"Our underground fortress is built among the mountains, surrounded by 13 high mountains, each of which has been hollowed out."

"On the 13 mountains, there are 2400 fortresses, 4800 main fortress guns with 2000mm super caliber, which can flatten a Tokyo city."

"Even if the 3000 meter ship of henggu is here, it can't stand our volley."

"Now there are only the Holy Son party on the holy star, and those chaotic parties are our enemies. Let alone they don't have such big warships, even if they come, they will be defeated with one shot."

"Assuming that all the fortress guns outside are destroyed, the enemy will come to this valley. We have prepared ten 100 million equivalent nuclear bombs and launched them on the principle of continuous explosion. Even if the enemy has a large defensive array, we can break them layer by layer, which is enough to wipe out all the creatures on the surface."

"The limit of the damage distance of a nuclear bomb is 1500 meters underground. We are below 2000 meters and are not harmed at all."

"The construction of NASA took five years. The liquid metal pouring technology adopted by NASA was a large iron box 2500 meters long and 400 meters wide. The wall was five meters thick and then buried underground."

"There is also a launch module at the bottom. In other words, NASA is a big all metal box, and it can fly. Once we feel that we can't defend here, we can fly ahead of time, go to other places, continue to command, and maintain the defensive ability of Shengxing."

Yan shengtu also felt that he was home after listening to this bull force.

All metal pouring, wall thickness up to five meters.

The five meter thick alloy is 20 times thicker than the wall of the warship.

"Don't say that the waste of the chaotic party is running around, even Ning Yi is useless. If he dares to come here, he can kill him directly." Xu Bai said triumphantly.

He is full of confidence. Ning Yi dare not let more than 4000 2000mm large caliber fortresses bombard him here.

People looking at the screen of more than 10000 warships, listening to Xu Bai's words, feel very interesting.

The warships of the three colleges are just outside. As long as the holy star stays at the holy star, they can't take the holy star.

Warships will also consume a lot when they stop in mid air. I believe they will withdraw soon.

It's just that we don't understand why all of a sudden the three colleges will come here.

When people were talking about why the three colleges came.

Fan Shiwen's eyebrows wrinkled: "Shh, don't make a noise."

"What for?" Xu Bai and others are inexplicable.

"Keep it down." Fan Shiwen reached out to them and raised his ears: "did you hear the sound of bang bang?"

"No? How can there be a bang? "

"Doodle, doodle --" at this moment, the whole control room was full of alarms.

Professor Gu's face changed greatly. He quickly controlled the computer. After pressing the key, he swiped the button and got the complete structural map of NASA on the screen.

At the bottom, left and right, 2400 meters below the ground, more than a dozen red dots are flashing, reminding us that there are faults in all these places.

"How could it be?" Professor Gu's face turned green.

"What happened?" Fan Shiwen asked in dismay.

"Someone launched an attack on us at 2400 meters underground. How could this happen?" Professor Gu was stunned. Even if the pangolin had to dig 2400 meters underground, it was impossible for him to hide from the world for a long time. Even they didn't know until now.

And the most important thing is that there are more and more red dots on the map, and they are getting bigger and bigger. It seems that something powerful is shuttling through the whole NASA, drilling through the five meter thick alloy.

The five meter thick Taiheng alloy, let the main naval gun to fight, for the same place to fight a thousand guns are not necessarily hit through.

"Boom" in this moment, the entire space agency a loud bang, earth shaking.

"Start, start now, take off now." Professor Gu exclaimed in horror.

"What? Is it going to take off? " Xu Bai is also incredible.

"Someone's coming in from under and around. Get out of here." Professor Gu is not finished.

All of a sudden, there was a loud bang, and the place he stepped on suddenly fell down. He was completely unprepared, ah, with a scream, he fell down.

"Professor Gu." There was a quick reaction on the side, and he grabbed Professor Gu.

People's mind, will, have swept to see.

The five meter thick wall of Taiheng alloy has been completely dug through. A golden black monster opens its mouth, and cacha bites Professor Gu's waist.

Puff Chi, below the blood shot, bone and flesh separation, Professor Gu below the waist, was all bitten off.

"Ah --" he uttered a terrible cry and died on the spot.

"What is this?" Fan Shiwen and Yan shengtu are just out of the world.

"Bang, bang."“ At this time, the surrounding walls and the soles of their feet were broken one after another.

From the place where Professor Gu fell, whoosh, a monster rushed out and rushed straight at Yan shengtu.

Yan shengtu's will moved, and a big axe appeared in his hand. He stood up and slashed it with the power of tearing the earth.

When he hit the gold swallowing beast's head with an axe, a spark splashed, and his axe rebounded.

Yan shengtu was scared out of the world, so he gave way and quickly avoided.

But see the ground constantly broken, a swallow gold beast rushed out.

The room was small and there were not many people. After a dozen gold swallowing beasts rushed out, the room was almost full.

This is bad luck for fan Shiwen and Yan shengtu. They are both immortal. If they are in the open space outside, they can escape immediately even if they can't kill the gold swallowing beast.

Now they are trapped in a narrow space. Although they are powerful and can continuously shoot out the gold swallowing beasts, they are invulnerable. In those days, Ding Yi relied on the branches of the towering tree to kill them.

After being knocked down for ten times, the gold swallowing beast can stand up for ten times, and there are a steady stream of monsters at the opening of the ground.

Waves of monsters rushed in, and they heard screams from every room of NASA.

"I can't keep it. It's over." They were frightened, and after attacking the gold swallowing beast again and again, they were not careful. A gold swallowing beast took advantage of their panic, and cacha bit Yan shengtu.

"Ah." Yan shengtu felt that half of his shoulder had been bitten off. It was dark before his eyes. Before he fell down, six or seven gold swallowing beasts jumped on him and bit him.

Fan Shiwen looked at Yan shengtu. In less than half a minute, he was eaten without leaving any bones. He was also in the dark and almost fainted.

"Who is it, and who are you?" Fan Shiwen screamed wildly.

In response to him, countless monsters came forward one after another and threw fan Shiwen to the ground.

"Ah --" he cried bitterly, watching his hands and feet bitten off.

At the moment when he was about to die, the cracked underground passage, whoosh, drilled out a head, the face, dimple, very lovely.

"Qian Ziniang" fan Shiwen vomited blood three times and died on the spot.
