Before entering the base, Lin Feng had made many ideas about the appearance of the base. After all, it would still be exciting for someone who loved watching American blockbusters in his previous life.

But when he really stood inside and saw the scene behind the door, he was still shocked.

It was a cylindrical natural pit with a diameter of 100 meters, extending vertically from bottom to top and a height of 100 meters. There is an unknown transparent material on the top of the pit to seal the hole, and the dense mesh alloy structure supports this transparent material.

Natural light can be shined through the hole, providing some lighting for the entire base.

In the center of the cave, a cylindrical device erected seventy or eighty meters high, making a low buzzing sound, and it seemed that it was still in operation.

The gate where Lin Feng and the others are located is in the middle and upper part of the cave, which is about ten meters away from the "top" of the cave. In front of him is an iron plank road built along the Tiankeng Bi, which extends windingly to the other end of the Tiankeng.

Lin Feng, who was the first to come back from his shock, walked forward a few steps, walked to the edge of the plank road, held the guardrail and poked his head out to look under the sinkhole.

"It seems like I've experienced something here." Lin Feng said with a serious expression.

When Yang Mi heard this, she stood carefully next to Lin Feng and looked down along Lin Feng's gaze.

I saw that the circular sinkhole cliffs below the two were densely packed with various research rooms and activity areas, at least hundreds or thousands of glass rooms. The rooms were connected by crisscrossing steel plank roads and stairs, looking like a huge spider web.

At this time, only about half of the rooms were on with lights. You can see through the lights that most of the rooms were in a mess, with crooked equipment, tables and chairs, and documents and papers scattered all over the floor. That feeling was like a typhoon just blowing here, which was a completely disaster scene.

Some electric sparks were sprayed out from time to time in some rooms, and the lights in the whole room were flashing and dimming. In addition, there was no living person in the huge base, which made Lin Feng and the others feel even more gloomy and terrifying.

"Damn, I won't have been attacked here..." Lin Feng whispered.

"I don't know what's going on. But you still remember the Overlord Salamander, Dabai and those zombies. Maybe the problem broke out from within them."

"Are you saying they were attacked by these things? Then... there aren't these ghost things in it, right?" Lin Feng felt a little cold on his back.

Damn, you must know that if those giant beasts and zombies were born here, then maybe there would be more dangerous species that you had never seen before. It would be a death for finding something in such a big place.

"Then where should we go now? You are from the Heavenly Eye, you... should know!" This time it was Lin Feng's turn to lose his opinion.

Just kidding, Lao Zhi doesn't want to cover his head and run around in such a place. If a corpse king really appears, prehistoric Tyrannosaurus Rex, I will explain it here... I hope this girl has an idea!

"Of course, the task is to find the database of this base, because all the research projects, research results and personnel files about this base will be stored there. Whether you want to investigate my grandfather's whereabouts or try to figure out what the Sky Eye is doing, you must find it."

"Where are you taking the database?"

"I don't know the specific location, but according to the unified standards for building each base, the database should be built at the deepest part of the base, usually underground... But considering that the base itself is underground, the database should be at the bottom of the sinkhole."

"Then...below?" Lin Feng subconsciously looked down.

The bottom of the black pit cannot even see the basic outline clearly, so you have to go down to the bottom? Who knows if there is anything weird below? His uncle's...

"But before this we have to find a computer to see what's inside!" Yang Mi took out the metal U disk.

"Okay!" Lin Feng observed around and found a room that looked more suitable. "It's closer, let's dive over first, you can follow me."

After Lin Feng said that, he walked towards the other side with his waist and his feet. Seeing this, Yang Mi followed carefully.

It seemed that it took the two of them seven or eight minutes to reach their destination. When they entered the room, they both breathed a sigh of relief, and a layer of sweat appeared on Yang Mi's forehead.

After all, in the empty environment, Lin Feng and the others were as small as two ants. They were tense and nervous even though they knew there was danger here but could not see any other moving objects.

After a short rest, Yang Mi quickly turned on the computer in the room and linked the USB flash drive.

"The storage device starts the automatic confidentiality program, please enter the password to unlock the device."

"Tip: The self-destruct program will be started after three consecutive errors in password input. Please enter it with caution."

This prompt appears on the computer screen.

"What should I do?" Lin Feng looked at Yang Mi sitting in front of the computer.

"It's okay, I have a way to untie it." After saying that, Yang Mi groped in her clothes for a long time, and finally found something that looked like a USB flash drive, and then connected it to the computer.

"Scan to the internal confidential storage device, will the unlocking program be started?"

Yang Mi chose "yes" without thinking.

Then a progress bar appeared on the screen.

Unlock progress 15…18…25…

"I'll go, you actually have such a thing? You're so cool, where did you do it? Help me get one." Lin Feng was very jealous of such things that crack passwords.

"Don't think about it, even if you give it to you, it's useless. This is a reverse unlocking program specially created by the people inside Tianyan for Tianyan's confidentiality program. It is only effective for Tianyan's confidentiality program. As for where it comes from, don't ask." Yang Mi stared at the progress bar in front of her, feeling that her breathing became a little rapid, as if she had already felt that the truth might be getting closer and closer to her.

"Drip...Unlocking is completed, the master turns on the storage device."

Yang Mi took a deep breath and resolutely chose...
Chapter completed!
