"Be vigilant and be aware of changes in your surroundings at all times."

Luo Xiao whispered to remind the soldiers who were walking in the front to be more careful, and he and several fighters behind him also raised their vigilance to guard against crises that could arise at any time.

By now, Luo Xiao could basically be sure that the warriors who came in earlier were likely to die under the sudden eruption of magma, and in such a bad environment, if there was no unguarded sudden encounter, then what awaited people could only be death.

Even he, if he hadn't thought of the cause of death of those who had taken the lead in time, he probably wouldn't have escaped this sudden crisis.

Now, the warriors who followed him into the cave had already sacrificed three or four, and the rest of the people had also exhausted their strength because of the situation just now, and although they had rested for a while, they had only recovered a little.

As for stopping and resting for a long time, Luo Xiao didn't dare at all, who could know that there would be no other sudden changes here, especially the big crack, if magma erupted from it, several people would have to explain here.

In this way, the people followed the fork in the cave and entered another cave and continued to walk forward.

Along the way, people tested their surroundings with instruments and found that the altitude continued to drop and was now negative, meaning that they were below sea level.

After going through so many things at the beginning, people's endurance has become much stronger, and they can accept it calmly and move on.

The cave was very quiet, except for the echoing footsteps of a few people, there was no sound to be heard, only the pillar of light from the bright flashlight was slowly moving forward.

There was no sign of any lifeform on the instrument held in the hands of the soldier at the front, and there was nothing unusual on the other equipment, so it seemed that it was safe at least now.

The cave was not high but very deep, and it zigzagged to an unknown place, and people walked along the uneven ground, deeper and deeper into the belly of the mountain.

Luo Xiao raised his wrist from time to time, calculating the time when he entered the cave, he knew that it was about to reach the time agreed with Huang Cheng, but it seemed that his group would not be able to return to the cave in time.

Originally, I thought that Mo Yanran's communicator could keep in touch, but I didn't expect it to be so weird in the cave, and they lost contact as soon as they came in, especially when they encountered the eruption of magma, which cut off their way back, which made them have to rush forward.

As for the connection with the outside of the cave, Luo Xiao could only hope that Huang Cheng would be less impulsive.

At this time, outside the cave, Huang Cheng had already become an ant on a hot pot, walking back and forth. Luo Xiao and the others have been in for a long time, and they will soon exceed the scheduled time, but there is no news at all, and even the signal is blocked, which makes him very anxious.

The signal was blocked, Huang Cheng believed that it would not be Luo Xiao and them who did it themselves, they must have encountered something, and the soldiers of the team sent a few times before suddenly lost contact, he knew that there must have been some accident.

Constantly looking at his watch, Huang Cheng saw that the hour hand pointed to the appointed time, he turned his head and shouted at the soldiers on the side, "Commander, have they responded?" ”

"Report to the captain, no!" The warrior kept adjusting the frequency, looking for even the slightest hint of signal inside, and when Huang Cheng said this, he hurriedly responded.

"Grandma's, I can't wait." Huang Cheng grabbed the special operations helmet placed beside him and strode towards the entrance of the cave.

The soldiers hurriedly grabbed him, "Captain, didn't the legion leader say before leaving, once they didn't come out at the scheduled time, let you quickly notify Engineer Mo Yanran at the test base?" ”

Hearing what the soldiers said, Huang Cheng woke up, hurriedly grabbed the encrypted phone, and dialed the test base, "How did I forget this stubble." ”

There was a waiting tone on the phone, which was quickly connected, and a woman's voice came from inside, "Test base, who are you?" ”

"Hello, I'm Huang Cheng of the wolf pack team, please help me find Engineer Mo Yanran, just say it's the order of Captain Luo Xiao." Huang Cheng hurriedly said inside.

The phone answered, that is, more than ten seconds later, it seemed to be transferred to another place, and a female voice came from inside that was clear and didn't seem to have any emotional fluctuations, "I'm Mo Yanran." ”

"Engineer Mo, Captain Luo has an accident again." Huang Cheng has unconsciously used the word again, it seems that it is not the first time that Luo Xiao has this criminal record.

Also, since he came to this era, he has had enough troubles, and he has risked his life again and again, and his life has hung by a thread several times, that is, he has survived because of his fate.

As soon as he heard that Luo Xiao was in danger, the voice on the other side of the phone immediately raised an octave, and his voice was full of anxiety, "What's the matter, where is it?" ”

Huang Cheng briefly introduced a few words on the phone, and there was already a noisy voice on the other side of the phone, it seemed that Mo Yanran was gathering the team, and then heard her say in a deep voice, "Let's rush over immediately, you wait in place, don't rush into the cave." With that, he hung up the phone.

Huang Cheng put down the phone, the worry in his heart did not diminish at all, he stared at the black hole, and muttered to himself, "Commander, you must not have an accident." ”

In the experimental base, Mo Yanran answered the phone while walking out of her office and towards the hall of the experimental base, and it could be seen that she was already anxious.

Although she didn't show up when Luo Xiao left, it didn't mean that she didn't care about Luo Xiao, on the contrary, she found that her feelings for him were too deep, and they were all imprinted into her-, for her, she would only like one person in her life, but once she liked it, this life would never change.

Rushing into the experimental hall, Mo Yanran sounded the alarm, and the piercing scream instantly alarmed all the people in the experimental hall, and everyone put down what they were doing, looked up at Mo Yanran, and didn't know what was going on.

"Group 2103, immediately follow me to the mission." Mo Yanran didn't say anything, and gave the order directly.

Everyone in the laboratory was shocked, of course they knew that the 2103 group, which was a group composed of top scientific researchers in the test base, could be said to be the essence of the entire test base, and they were usually cared for as treasures, but they didn't expect Mo Yanran to use them this time

Mo Yanran ignored everyone's exchange of words, turned around and walked towards the No. 1 factory on the side, and dropped a sentence as she walked, "Gather on the apron of the test base in five minutes, and bring all the most advanced AS equipment." ”

Now people are even more surprised, you must know that AS equipment is related to field search and rescue and geological survey, what is the use of Engineer Mo asking for these things?

"Could it be—" Aya thought of Luo Xiao and Mo Yanran's actions today, her heart sank suddenly, and she hurriedly ran towards her residence, because he was also a member of the 2103 group.

Five minutes later, a team of dozens of people appeared on the tarmac at the entrance of the test base, and carried a large number of instruments and equipment with them, filling most of the apron.

A group of soldiers from the heavily armed Huya Special Operations Brigade were ordered to arrive, and they would be responsible for protecting the lives of these Yanhuang Legions and ensuring their safe return to base.

A huge transport plane quietly parked on the tarmac, this is a transport plane with a length of more than 20 meters, the shape is like an eagle flying with wings, the streamlined shape is faintly strong, and the strong power system allows it to easily carry hundreds of tons of weight, and it can continue to fly for three days and three nights.

This is a successful trial production of the test base Eagle transport aircraft, the crew quota is 500 people, in addition to can carry 100 tons of cargo, is Mo Yanran led the scientific research team newly developed, this is a test machine, has passed the test, will be put into mass production soon.

Unexpectedly, its first flight was carried by the elites of the Yanhuang Legion Test Base, as well as the top equipment.

"Get on board!" Mo Yanran changed into a tight-fitting special combat uniform, buckled the steel helmet on her head and fastened the straps, then inserted the two pistols into the holsters on her legs, and then scanned the crowd and shouted.

The crew boarded the transport plane with the door open in order, and then the equipment was also transported by the automatic handling equipment, and the door was closed again.

With the roar, the transport plane slowly rose into the air and flew towards the outside of the underground base, and to its left and right, four Hippo armed transport planes and eight armed attack helicopters also quickly rose into the air, carrying 200 members of the Huya Special Operations Brigade to protect the transport plane.

Mo Yanran watched the transport group go away, she opened the porthole of the Flash No. 1 and jumped into the cockpit.

With the push of a few buttons, the Instant One flew up and flew towards the outside of the underground base along the dedicated passage, and disappeared into the depths of the passage in the blink of an eye.

In the last battle of Port Arthur, although Mo Yanran's Flashing No. 1 was struck by lightning and malfunctioned, it had already been repaired after coming back, in view of the particularity of this special fighter, the legion later decided to leave it to the experimental base, and Mo Yanran was responsible for maneuvering and using it.

However, since that time, Mo Yanran has never touched the Flashing No. 1 again, and let it sleep on the tarmac for a year.

Today, because Luo Xiao was in danger, Mo Yanran finally stepped into the cockpit of the Flashing No. 1 again and began to drive it again.

"Control to connect!"

"Control connection is normal!"

Start the system intelligent control!

"The intelligent system starts up normally!"

"Now transfer control!"

With the issuance of one instruction after another, Mo Yanran felt that she was one with the Instant Flash No. 1, the Instant Flash No. 1 was herself, and she was also the Instant Flash No. 1, and an unprecedented sense of ease hit her heart.

Whew, an ultra-difficult 720-degree rotation, Flash-1 rushed out of the edge of the passage, rose into the sky, and then chased the group of transport planes in front.
