"Who will touch the whistle?"

"I'll go!" A major with a scar on his left cheek lowered his head, saying, "He was Leng Ying, the battalion commander of the reconnaissance battalion.

"Be careful."

Pulling apart the branches, the major was like a raccoon cat, and in the dark night, he moved very quickly. He flashed a few times and approached the position of the Yu clan's post.

Click!

Two crisp sounds were sent in the breeze.

With good skills, Mu Feng's eyes lit up. This major is not weak and he is a talent.

"Let's go!" Mu Feng waved his hand, and the team stood up one after another and moved forward quickly.

It is really not something that ordinary people can do to avoid the Yu clan's integrated aerospace investigation, and it is beyond the reach of advanced equipment.

After all, technological progress is driven by human wisdom.

"When designing this fortress, there were almost no blind spots on the south, west and north, and the east side was facing our side. In fact, when designing, the designer was actually careful..." Mu Feng lay in the crater, observing and explaining to Wu Wei.

"General Wu, you seem to be very familiar with this fortress fortress?"

"I have studied this action specifically," Mu Feng explained.

Wu Wei nodded. This explanation makes sense. This is a top-secret mission and it also requires infiltrating into the territory of the Yu clan. He dare not inquire about what he does, but it must be a secret of the federal government.

Therefore, there is a reason for others to do their homework.

"Generally fortresses like to set the vents diagonally downwards and create a 'z'-shaped passage upwards of the entrance. The vents are very small, and most people will definitely get stuck when entering. The ventilation channels have infrared detection mechanisms. Once foreign objects invade, the laser knife will start quickly. It can be said that there are no blind spots to prevent them, but the secret door I mentioned is also a vent..."

Mu Feng's explanation is very clear. There are eight external vents in the fortress, one of which can be safely entered. Of course, this one is not absolutely safe.

It is safe to have a distance.

This is a safe passage left by the designers' ultimately weighing the pros and cons. One is to give the soldiers guarding the fort a chance to leave alive when they cannot resist, and the other is to provide a chance to break through from the inside fortress.

"Everyone come with me, be careful to follow me, there are mines buried in the vent!"

"Did the landmines be buried by us or by the Yu people?"

"From the nearby environment, we should have buried it. The soldiers of the Yu clan should know, but I don't know if they have moved their locations."

"It shouldn't be possible. Remove the mine and bury it again. Is it a bit like taking off my pants and farting?"

"I hope so." Mu Feng nodded. If he were the commander of the Yu clan in this fortress now, he would have to do this kind of thing that takes off his pants and farts.

There are really dense landmines under this rocky beach, and they are all powerful directional mines, specifically targeting enemies sneaking over here.

"Be careful, in addition to landmines, there are traps buried underground, with poisonous needles inside. They will not die immediately when they are in, but they will immediately paralyze all over the body and wait for death..."

"It's so poisonous, who designed it?" Wu Wei couldn't help but wipe his forehead.

"Jonasser Hayre."

"That genius in the design world, legend has it that he was in charge of designing and building the Federal Presidential Palace, the Parliament Building, and the headquarters of the five major war zones. He was in charge of designing and building?"

"It's him."

"Is such a small fortress designed by him?" Wu Wei felt a little incredible. Will such awesome person condescend to design a defensive fortress?

"This is a design from his early years, and probably not many people know it now." Mu Feng smiled. If he hadn't discovered the security secret passage, he wouldn't have paid attention to the designer of the fortress.

This is actually not a military secret. You can find it by checking it online, but now basically no one will pay attention to it.

Even a frontline commander like Wu Wei didn't know who designed the fortress he was trying to conquer. How could others know?

Of course, not knowing who the designer is, this has nothing to do with the task of capturing the fortress, but understanding the past and present of the fortress should be what a qualified commander should do.

At this moment, Wu Wei's face was a little red with shame.

After passing the stone beach, the fortress was already in front of you. Of course, this was just a feeling, at least it had to cross a blockade line and the positions of the Yu army.

Fortunately, Wu Wei and his team chose the main attack direction to be the southeast. If they chose the northeast direction, it would be a problem. It would be much more difficult to get in through the Yu clan's blockade line.

"Sniper rifle, silent bullet."

Ma Wu handed Mu Feng over the sniper rifle behind him and handed him a magazine.

"We can't get around this blockade line. We must fight, but we cannot alarm the people inside. Therefore, we use all silent bullets and you will hit it with one blow!"

"clear!"

"Okay, listen to my orders, Brigade Commander Wu..."

"There are a total of sixteen people, which is a typical combat squad for the Yu army. We have a total of thirty-three people, almost two-on-one..."

In the defense tunnel.

"Captain, I heard that women in the Federation are all very beautiful, with big N sons and fair skin. They are much better-looking than women in our Yu clan!"

"You boy, your breasts are not clear yet, and you just miss a woman?"

"Think about it, you won't be a crime, right?"

"Of course, when we win the Federation of Humanity, we will rush to their city to grab them, grab their wealth, and grab their women. Then let the captain find two beautiful ones for you and take them back to be female slaves..."

"Captain, is it true?"

"Really, it's more real than real gold. However, this federal person is not easy to deal with, so we should be careful." The captain of the Yu clan felt a chill in his neck and said with emotion.

puff!

The captain had a good premonition. As soon as he looked up, a high-speed silent bullet drilled into the back of his head, and there was no chance to make a warning sound, so he fell down directly.

Death comes so suddenly.

In an instant, a combat team of the Yu tribe who was defending this position was destroyed by the assault team.

"Sweep the battlefield and don't have any fish that misses the net."

"yes!"

This is the experience obtained by using blood on the battlefield. Often such a small negligence will ruin the lives of the entire team and even the victory of the entire battle.

"Report, I have a living person, I seem to be young..."

"What did he say?"

"It's the language of the Yu clan, it seems to be talking about some female slave..."

"Who will?" Mu Feng pulled out the alloy dagger he was with him and asked, "This kind of prisoner is basically of value."

"I'll do it." The major reconnaissance battalion commander stepped forward to take the dagger from Mu Feng's hand and cut the Yu soldier who was still breathing.

He is clean and neat, and he is a cruel person.

After wiping the blood, the major returned the dagger to Mu Feng.

"What's your name?" Mu Feng asked.

"Leng Ying, my subordinate!"

"Leng Ying, it's not bad, I remember you." Mu Feng nodded. The major was taciturn, but it could be seen that he was definitely an experienced iron-blooded warrior.

"It's here, go down from here."

Break open the small hidden door of the energy shield.

A deep well worth more than ten meters, slippery. Even if the people here escape, how could they come up?

Of course, this is not the question Mu Feng and his team are considering now. They are going to go down from here, which is much easier. Thirty-three people quickly reached the bottom of the well along the other.

The bottom of the well is an upside-down horn.

"Eagle, which one of these four holes is taken?" Wu Wei turned on the tactical flashlight and found that there were four holes. Which one was the correct entrance.

"These four entrances are changing. If you go wrong, you will never be able to come out again. But don't worry, I know the right entrance." Mu Feng explained.

“What day is today?”

"October 23, what's wrong?"

"I know which entrance is, everyone will follow me." Mu Feng calculated in his mind and greeted him quickly.

"Let's go!" Wu Wei and others hesitated for a while, but still followed Mu Feng's footsteps.

The entrance is indeed very small, and you still have to climb up. After about seven or eight meters, there is a turn, and it seems to go down, and the passage gradually becomes spacious.

Mu Feng is right.

"Be careful, don't make a sound, we're already in." Mu Feng turned his head and called the sign language command.

Fork road!

After encountering at least three times, Mu Feng stayed for 10 to 20 seconds each time, he chose a channel and headed forward for about five minutes, and advanced at least hundreds of meters.

Seeing a slightly raised stone slab in front, Mu Feng breathed a sigh of relief and arrived.

"Eagle, what is this place? Why does it look like a prison cell?"

The iron fence is cold and damp, and it smells moldy...

"That's right, this is the prison cell. When it was built, it was originally intended to be used to detain prisoners of the Yu clan." Mu Feng nodded.

"Who came up with this escape passage in a prison cell?"

"Who could have thought of it?" Mu Feng asked back.

"That's right, I wish I could escape from this place. Who would have thought of a glimmer of life here?" Wu Wei nodded, "This design is really amazing."

"We have two groups of troops. I'll go to the command center. You can turn off the electromagnetic rail guns. We will work together with each other."

"good!"

In the 523 Fortress, Mu Feng was naturally like a fish in water. After more than half a year, he revisited the old place. There was basically no change here. He would not make a mistake even if he closed his eyes.

Although the Yu clan occupied the fortress, they were not familiar with it. How could the owner Mu Feng be familiar with it?

He led the squad to the command hall of the fort without any effort.
