Such a secret secret stronghold had not even been entered by Tang Xiaoxi, Mu Chen actually knew about its existence, and Tang Xiaoxi's level was not enough to enter this secret base.

The secret base of the Special Intelligence Agency is a first-level prevention and control early warning system, which uses the most advanced infrared human body sensing technology to automatically scan and identify the human body.

This base is basically the most elite members of the Special Intelligence Bureau, which belongs to the secret weapon of the Special Intelligence Bureau, they are basically trained by Director Xie, they are also the most elite members of the Chinese Operational Team, they are the strongest backbone of the Chinese Army.

Tang Xiaoxi followed Mu Chen to an overpass near the airport, he looked around, it was all a reinforced concrete wall, where was there a secret base.

"Is this the place?" asked Tang Xiaoxi curiously.

Even if Mu Chen and Director Xie were good friends, Director Xie would not leak the news of this secret base to Mu Chen, and the discipline of the Special Intelligence Bureau was even stricter than that of the army.

How did Mu Chen know about this secret base?

"Yes. Mu Chen said lightly.

"How come there is nothing. Tang Xiaoxi looked at Mu Chen even more puzzled, this kid wouldn't be Kuang her!

"We need to wait. Mu Chen said lightly.

"What are you waiting for. Tang Xiaoxi became more and more curious, what kind of person Mu Chen was.

"You'll know when the time comes. There was a faint smile on the corner of Mu Chen's mouth.

When the first rays of the sun shone into the lake below the overpass at five o'clock in the morning, a miracle appeared at this time, and a huge and magnificent building appeared in front of Tang Xiaoxi.

Tang Xiaoxi once heard others say that the secret base is so big, but he didn't expect it to be so big, where is this base. It's an undersea palace. The neat glazed tiles are carved in rows with a shield, on which each falcon has a different totem, or spreads its wings and flies, or spreads its claws, or shows the appearance of a pounce, this pattern is the symbol of the Secret Service, representing the loyalty of the defenders, loyalty to the country, loyalty to the people.

This totem reminds them to be like falcons and to sacrifice their lives for the security of the homeland and the happiness of the people at any time.

They are the most loyal guards of China, the shields that protect the land, and they have long forgotten their names.

Here they have only one name, which is Falcon, and to distinguish them they are called Falcon One, Falcon II, Falcon III, and so on.

The marble pillar made of white marble is carved with two soaring dragons, as well as a fence made of pear blossom wood, this is only the periphery of the base, Lin Yuchen took Song Qian's hand and walked through the green lawn, the space inside is really big enough, Tang Xiaoxi feels like he is in a dream, beautiful, overwhelmed, it is really spectacular.

The expression on Mu Chen's face was flat, he didn't seem to be surprised, as if he had returned to his own home, which made Tang Xiaoxi even more curious, what kind of person Mu Chen was.

Walking through this large meadow, Mu Chen and Tang Xiaoxi came to a statue made of two stone lions, each with a steel ball in its mouth, if it weren't for their eyes made of stone, this appearance of teeth and claws would really be mistaken for a real lion.

It's really spectacular, much more imposing than their secret service office.

"Stop, what are you doing? A cold voice interrupted Tang Xiaoxi's thinking.

Tang Xiaoxi followed Mu Chen into the house at this time, and what caught her eyes were two tall and burly, serious-looking, and cold-eyed two young people, even a few years younger than her, who looked like they were about the same age as Mu Chen.

"You see, of course you want to go in. Mu Chen said lightly.

Hey, he dared to be so arrogant in the Special Intelligence Bureau, and Mu Chen was also the best Tang Xiaoxi had encountered.

"I said, boy, don't look at what kind of place this is, is this a place where you can spill around?" said one of the young men's playful voices.

"Of course I know this is a secret base for the Secret Service. The corners of Mu Chen's mouth were raised, and he still had that light smile.

"Now that you know, why do you dare to be so arrogant. The man was indeed a little surprised, this person is not very old, where can a fool dare to go wild here, it is really too bold.

"Then this is a secret base, do you think others can come in?" Mu Chen smiled playfully.

These two guys are stupid.

Tang Xiaoxi also said in his heart.

The two young men looked at each other, Mu Chen was right, the secrets of this secret base that only a few people knew, not insiders, or leaders, otherwise no one would come here, as for those foreign forces who dared to come here, it would definitely make them have no return.

But these two faces are very raw. They were sure they hadn't met the two men, and the Secret Service had its own identification system.

"Password. The young man said coldly.

"Why, you don't even know about this, do you. Another young man said impatiently.

Interestingly, Tang Xiaoxi also showed a sweet smile.

"Can you two brothers start up, or you can say the first sentence and I will say the next. Mu Chen smiled peacefully.

"Yes, but you don't have to climb relatives, we have seen a lot of people like you. The man said coldly.

Maybe it was Tang Xiaoxi's sweet smile that made people feel like they were bathed in the spring breeze, and the nervous hearts of the two young men slowly relaxed.

There was a shallow smile on the corner of Mu Chen's mouth.

"The Heavenly King covers the tiger. The young man on the left said.

"The river demon of Pagoda Town. Mu Chen hadn't answered yet, Tang Xiaoxi had already rushed to answer.

It's too simple, when did the Secret Service become so lax.

"Eh, you think this is the old-fashioned plot of the TV series!" the man's disdainful voice came.

"I'll give you one last chance. If you can't answer that, then you need to stay here for a while and be investigated. The lazy voice of the young man on the right came.

"The Heavenly King covers the tiger. ”

"Serve the people. ”

"Chicken stew with mushrooms. ”

"Huaxia should be self-reliant. ”

"Poof. Tang Xiaoxi really couldn't help it, who came up with the password so funny.

The two young men looked at each other, and the young man replied well.

"Can we go in?" Mu Chen said lightly.

"Wait a minute, you also need to pass our infrared induction validation test. "The password may be able to get through the barrier, but the infrared sensor device automatically captures the body's temperature and implements thermal imaging technology to identify the person's identity.

Mu Chen smiled faintly, interesting. This technique will one day be applied to him.
