After Dou Ya opened the import and exit, she chuckled at Lin Feng and said, "Accident? Actually, there is one thing you guessed correctly. There is indeed an entrance and exit behind this huge rock. However, there was a mountain collapse here that year. The stone rolled down from the mountain and blocked the entrance and exit. After blocking it, our designer of the Soul of Yanhuang suddenly had inspiration and simply blocked the stone and dug a tunnel from the ground. In this way, the concealment was improved a lot. How about it? Are you quite interested?"

Lin Feng touched his chin, thought for a while, and said, "I do have an idea, but why do I feel a little awkward? It's easy for us to get in. How did Xia Qing get in last time? She was put on a stretcher? This entrance and exit are too..."

Lin Feng was indeed unable to complain. The entrance and exit were about the same size as the sewer manhole cover, and he didn't know how Xia Qing got in.

"Senior brother, you are too stupid. The cunning rabbit has three caves, not to mention such a large base. If there are not many exits and only one is blocked, we will be wiped out? As for the other entrances and exits, they are all in a secret state, you can know this!" Dou Ya said, and was the first to climb down.

Lin Feng was too lazy to ask more questions, so he followed him and climbed down.

After they went down, they came to a small room about ten square meters, and a password door was facing them.

Dou Ya walked to the door, first with a fingerprint, then a password combining the numeric letters, and the final iris detection, which was very complicated.

Lin Feng couldn't help but complain: "No need to do this, it's just a door. It's so troublesome. It's so exhausting to enter the door every day."

"What do you know? This is the most important secret base. If the enemy easily breaks in, what should the important scientific researchers inside? Tell you the truth, don't think that Ningbei is a small city. In fact, this is one of the three major bases of our Soul of Yanhuang in the south. Because of this, the superiors attach great importance to the affairs of the Pure Land of Wonderland. They repeatedly urge us to do things well. Forget it, it's useless to talk too much to you. You are not interested in these things. Go in quickly." As soon as Dou Ya finished speaking, a metal door of one or two meters thick slowly opened. In an instant, the white light almost blinded Lin Feng's eyes.

He seemed to feel like he opened the door to a new world. How much does it cost to make such a big deal?

What appeared in front of him was a long corridor, made of white metal, and the degree of strength was imagined.

Fortunately, Dou Ya was leading the way, otherwise Lin Feng would definitely be dizzy, because there were too many forks here, and there would be a crossroads at a time, and then another three forks at a time. Lin Feng felt dizzy as he walked.

He didn't understand, what was the silly base designed by this ×, isn't his brain broken? Isn't this special code just a maze!

"Senior brother, you must follow me closely, otherwise you will get lost. This is also the first barrier of our underground base. It was built after reference to the Nine Palaces and Eight Trigrams I studied by my master and the old man. If you don't move in the right way, you will be trapped here forever. If I open all kinds of traps in it, those who enter this place will almost die! Because of this, I am absolutely relieved to put Xia Qing here, and there will definitely be no problem!" Dou Ya spoke firmly, and Lin Feng couldn't help but feel a little embarrassed. If Dou Ya knew what he was thinking just now, she would probably get angry.

Dou Ya took Lin Feng for a few more turns before coming to the base.

This is a vast space. Lin Feng looked up and couldn't see it at first sight.

The huge project volume is evident when a mountain has been hollowed out like this.

Twelve giant steel pillars stand erect in various places, countless light bulbs are densely packed, illuminating the mountain into daylight.

Looking around, there are all kinds of small buildings everywhere, and the houses are not tall, with only three floors at most.

There are roads connected between each house, and many men and women in white coats are walking around, even ignoring Lin Feng and Dou Ya.

Lin Feng's eyes scanned around like a scanner. Soon, his eyes narrowed slightly, and a smile appeared on the corner of his mouth.

With a simple scan, he found no less than twenty firepower points. In addition, some patrol soldiers were full of true energy, and there was no problem in fighting one and three.

It seems that there must be special ancient martial arts masters training these people, and the foundation of the Soul of Yanhuang is not simple.

Lin Feng can't estimate how many masters you have to invest and how many people you die if you want to capture this place.

"Senior brother, are you very curious why this base is full of those people wearing white coats?" Dou Ya saw that Lin Feng did not speak, and said something to break the silence.

"Didn't you just say it? Those are scientific researchers. By the way, what are they studying? Why are they hiding in the mountains and making it so mysterious?" Lin Feng's curiosity was ignited and he asked with great enthusiasm.

Dou Ya smiled and said, "Of course they are studying some amazing things. The reason why they are so mysterious is to prevent assassination and destruction of hostile forces abroad. Here we gather real top talents from Yanhuang. These talents come from various fields. Here, they can display their talents and study anything they want to study. From the development of the first nuclear bomb in Yanhuang back then, countless top high-tech achievements have been produced here. In fact, if you don't take action, at most one year, the cracking method of the Pure Land of Wonderland will be developed. Nowadays, some experimental drugs have been launched, but unfortunately, the side effects are too great and cannot be tested on humans for the time being."

Dou Ya's words changed Lin Feng's expression slightly, and he said, "So powerful? No wonder the defense measures here are done so well. If something goes wrong here, it will be an incalculable loss for us Yanhuang."

"That's of course. But don't worry, even if the nuclear bomb is not destroyed, this base cannot be destroyed, even if the enemy invades, it can be eliminated in a very short time. Because of this, I asked someone to send Xia Qing here. Only here can she not be silenced. By the way, senior brother, there is also the most complete medicinal material library in China. You can directly say whatever medicinal materials you need later. We will do our best to meet all your requirements!" Dou Ya said confidently. While speaking, they had already walked to a two-story building.

Two soldiers with live ammunition were standing at the entrance of the small building. When the soldiers saw Dou Ya, they immediately saluted, then took out a card and stroked the slot on the door.
