In the pitch-black cave, Mo Yanran and the soldiers who followed her into the cave were all moving fast, and at the front of them was a multi-functional detection robot, exploring the way in the front.

This robot was recently developed by the experimental center, and it has a relatively wide range of uses, and this is also the first time it has been used. It is about 1.5 meters tall and has a heavy chassis underneath, traveling on twin tracks, a body made of alloy on top, eight robotic arms on either side of the body, and a high-intensity searchlight on the top head, which illuminates the surrounding detection environment. As for infrared detectors, night vision detectors, ray detectors, laser imagers and other high-tech equipment are all equipped in the body, with a wide range of applications.

The detection robot was walking in front, and Mo Yanran and them were about a few dozen meters away, and they were also carrying a lot of equipment in case of emergency.

Therefore, the members who entered the cave all changed into a set of protective clothing, which can not only protect against a certain strength of fire, but also prevent cold, poison gas, and radiation and nuclear radiation, which is much stronger than those biochemical suits, and the only disadvantage is that the tenacity is limited and cannot be used on the battlefield.

This is also the latest technology in the test base, and it is stored in the warehouse after production, and it is easy not to use.

This time, for Luo Xiao, Mo Yanran moved out of the experimental center, because according to Huang Cheng's description, Mo Yanran had already noticed the abnormality of the cave, and it was estimated that there would be danger inside.

Since entering the cave, Mo Yanran has not said a word, commanding the detection robot to walk in front, collecting surrounding data as it advances.

Rocks, microorganisms, air, traces, and things that are invisible to the naked eye have all been collected by her in special containers, and she has studied them as she goes.

All the way was very smooth, and the vigilance of those soldiers relaxed a little, they felt that this was nothing more than that, and there was no danger.

However, Mo Yanran's expression became more and more solemn, because through analysis, he seemed to have learned something.

The people continued to walk forward, and it took about half an hour to finally come to the forked in.

"Stop!"

Mo Yanran gave the order through the walkie-talkie, and this was the first time she had spoken since entering the cave.

People hurriedly stopped, alerting their surroundings, and although they didn't see anything unusual, they were all trained elites, and they reacted naturally.

Mo Yanran stepped to the fork in the road, looked at the two holes, and then began to observe carefully, and there was no movement for a long time.

People waited patiently, and after ten minutes like this, Mo Yanran moved, she stretched out her finger and wiped it on the hole on one side, then withdrew her finger and looked at the water stains on her finger.

This is a touch of light blue water stains, which are no different from ordinary water stains to the touch, but the color is a little different, and there seems to be some blue crystal powder in the transparent water stains, so this water stain exudes a faint blue color.

Taking out a suction device, Mo Yanran sucked the water stains attached to the stone wall of the cave into a test tube, then inserted the test tube into an instrument he carried with him, and then pressed the button.

With a beep, a red light on the instrument flashed, and then the data on the display flowed down like a waterfall for more than a minute, and then the tick stopped, leaving a string of data.

"What, it's really-" Mo Yanran's gaze swept over the string of data, and her eyes suddenly widened, and she could see that she was full of shock.

After staring at the string of data for a while, Mo Yanran breathed a sigh of relief, then raised her hand and wiped it on the display screen, erasing the string of data, then stood up and shouted at the soldiers, "Quick, enter the passage!" ”

The soldiers didn't know what was going on, but since they had given full command to Mo Yanran before coming in, they naturally obeyed unconditionally and quickly entered another cave, that is, the cave that Luo Xiao and they entered......

After everyone came in, Mo Yanran didn't move, leaned around the entrance of the cave and looked out, as if waiting for something to happen.

"Captain, why hasn't the team moved forward?" A platoon commander who led the team leaned over and asked.

Mo Yanran waved her hand, but she didn't look back, "Wait!" ”

Not knowing what to wait for, the platoon commander could only retreat with a question mark on his head and continue to wait patiently.

"Well, there's thirteen seconds left, so it's supposed to be here." Mo Yanran raised her hand to look at the watch on her wrist, and whispered to herself, "I want to see if it's what I think." ”

More than ten seconds was instantaneous, and when the second hand reached the position predicted by Mo Yanran, he heard a piercing scream from outside, followed by a chill sweeping from outside, and even people wearing protective clothing felt a little trembling.

But fortunately, the chill came and went quickly, and disappeared in the blink of an eye, as if nothing had happened just now.

Mo Yanran turned around and walked out of the cave, standing outside the cave entrance and looking at the silver-covered world around her, and finally confirmed that her guess was correct.

"This--this-this-what's going on?!" The warriors poked their heads out, only to find that the place where they were just now had been frozen in ice, and now there were crystal clear ice crystals everywhere, and the blue crystals that emitted a faint light set off the whole cave very brightly, as if it was a fairyland.

Mo Yanran came to the alloy rod she deliberately left just now, touched it lightly with her fingers, and heard a click, the alloy rod actually broke, and after falling to the ground, it turned into pieces in the blink of an eye.

People were stunned, they had seen the hardness of the alloy rod with their own eyes, but they didn't expect it to be as fragile as glass under these ice crystals, and it would shatter when touched.

"If we had been here just now, we would have encountered that kind of cold snap...... "People didn't dare to think about it anymore, and they couldn't help but swallow their spit and retract their heads back into the cave.

"The time interval is one hour and eleven minutes, with intermittent regularity...... well, that's important." Mo Yanran recorded these in detail, and then nodded with satisfaction.

At this time, she saw the warriors who were probing their brains at the mouth of the cave, and she couldn't help but smile in her heart, "It's okay, it's safe here for at least an hour." ”

That's when people were relieved.

Mo Yanran looked at the surrounding environment, and finally chose a place, and pointed with his hand, "Build the first overclocked communication equipment here." ”

This time, there were several technicians who accompanied the trip, and they immediately set to work, and soon the first basic communication station was built.

Mo Yanran grabbed the encrypted phone and dialed Aya's side, and suddenly Aiya's shout came, "Sister Yanran, how is the situation on your side, we haven't been in touch for an hour, and we are all dying." ”

"I'm all normal, don't worry." Mo Yanran replied calmly.

After exchanging some information with Aya, Mo Yanran led the team and continued to walk inside, and they walked in the cave where Luo Xiao and the others were advancing.
