There is nothing special about the mission that the third shift went to Raccoon City to perform, it is just the second batch of routine batch missions, and they have already gone to a group of troops before, done some infrastructure and reconnaissance, and then came back smoothly very quickly.

When the helicopter flew to raccoon, due to the time difference, it was day and night in country A, and it was time for Xu Xiaoting to sleep, and she felt a little drowsy, while the other four people in the cabin remained awake and vigilant. The soldiers of the third squad have seen part of the video materials of the raccoon battle, especially the scene of the "giant bat" attacking the helicopter, which is very fast and disturbing, although it is daylight, the "giant bat" is unlikely to attack, but Raff and Casey are standing in the machine gun battery in the engine room, and they rarely speak, as if they are looking forward to the helicopter's radar to send an early warning, and then they shoot as much as they want, and beat those ugly monsters into a honeycomb.

"Do you really think it's as easy as hunting birds?" At some point, Brice suddenly said to Raff and Kathy, "That thing has a shell, it's hard, and if the bullets hit it, most of it will be ejected, forget?" ”

Raff and Casey perfunctory Briss said that they didn't mean anything else, they just wanted to practice their hands and stay focused so as not to doze off.

Soon the helicopter was over the ruins of Raccoon, and it was 11:22 a.m., with little clouds and a bright sun. The details of the ruins of the city beneath the helicopter are already visible through the portholes, buildings, streets and vehicles.

“cool !” Raff let out an exclamation, but the exclamation was immediately questioned by Bliss.

“cool ?” "You should say damn!, because we lost the battle [at raccoon] and two scientists were kidnapped by those." It's not cool at all – but I'm going to jump for a while. ”

“cool !” Casey imitated Raff and said, "Enjoy your first robot skydive." ”

At this moment, the planned time for the robot to parachute has arrived, and the helicopter pilot prompts Xu Xiaoting and Briss that the rear valve of the cabin is opening and it is ready for parachute testing.

This is part of Xu Xiaoting's test work on the X2117A, and Briss and her skydive together just to take care of each other, just in case. The other three will descend to the ground at a later date before exiting the capsule, as the operation carries some detection equipment that is not suitable for airdropping.

The other three people in Class 3 said byebye with Xu Xiaoting and Briss! Then, through the valve at the tail of the cabin, the two jumped one after another and flew out of the cabin.

After the robot flew out of the cabin, its sensors could not transmit the feeling of weightlessness to Sima Aya (Xu Xiaoting), who was far away on the other side of the ocean. However, just by looking at the swirling earth that was rushing towards him, and hearing the sound of the wind whistling in his ears, Sima Aya was already immersed in the scene, and he had a strong sense of vertigo.

At 11:50, 20 minutes after Xu Xiaoting's skydive, the five of them met in the ruins of Raccoon. The meeting point for the five was at a subway entrance in the heart of the city, and the subway sign read: Fifth Avenue Station.

Next to the entrance and exit of the subway is a signal base station that provides signals for the stand-in robot, which is a small tower, a little taller than a Christmas tree. This is the base station that the other squads of the 117th Battalion set up a few days ago after the battle of Raccoon. A python-like cable extends from the base of the base station, winding its way through the entrance of the subway station and continuing down the escalator. The cable is so long that the end is not visible.

"This is a 2-in-1 signal power cable, only the main cable." "It can be used to extend the signal, and at the same time, it can also be used to charge the stand-in robot." Below the ground, we're going to have to rely on it. ”

Xu Xiaoting naturally knows that when going deep underground, the satellite signal and the ground base station signal cannot be received by the robot, and although the method of extending the signal with a cable looks very cumbersome and crude, it is very practical, and there is no better way at present.

"Why don't these devices have indicators?" Raff seems to have noticed a problem, "None of them seem to be working." ”

Everyone saw that there were indeed no indicator lights flashing on the small tower and the base of the tower, which was different from the equipment in the conventional sense. At this time, Bliss walked over and said, "Raff, keep your eyes open. He opened a panel from the pedestal, with illuminated indicators and a fluorescent screen interface, "You find time to read the manual a few more times." ”

"It's all for fear that those ghosts will wreak havoc!" Briss said indignantly, looking at the others, "They'll attack glowing things. ”

Craven nodded to everyone as well.

After some preparations, the five entered the subway entrance. The electric lights, illuminated billboards, EXIT indicators, etc. in the subway entrances and subway passages, all of which are glowing objects, have been mostly damaged, which reflects what Briss just said. Although the ground was blue and white, the tunnels were dark, and the five had to turn on night vision mode - it was obviously not safe to use flashlights.

The subway station is empty, and the slightest sound will bring a huge echo that will never stop in the ears. After many reflections, the distorted echo sounded eerie, invisibly amplifying everyone's fear of darkness. Fortunately, according to the report of the squad on the last mission, during the course of the Raccoon mission, there were no witnesses to the enemy.

Xu Xiaoting carried a half-person-tall equipment box on her back, surrounded by four people in the middle, and walked cautiously. Inside the half-human-tall equipment box are secondary signal branch cables and portable signal transmitters, which allow the stand-in robot to go deeper into the ground. Compared to the X4G, the X2117A looks more slender, like a woman surrounded by four strong men, however, it is extremely incongruous to ask the woman to carry a large suitcase. But in fact, the slender body of the X2117A does not mean that it is weak and powerless, its material has higher strength, and the battery has more power...... The weight-bearing march is also one of the test items for the X2117A.

Five people walked deep underground along the main cable, and on the main cable, a branch signal station or branch charging connector was connected every other section.

"Signal and power are the ...... of the stand-in robot According to your C language: grain and grass. Xu Xiaoting remembered that Craven once explained to herself the characteristics of stand-in robot combat. Where there is electricity and signals, stand-in robots can survive. ”

As Craven said, the main cable is the lifeblood of the robot.

Soon, the five of them came to the subway platform on the second basement floor.

"Tang Dynasty beauty, report the data." Bliss said to Xu Xiaoting.

"Yes, corporal." Xu Xiaoting replied, she looked at the data that emerged from the visual plane of the helmet, "Nitrogen accounts for 78.03%, oxygen accounts for 20.65%, argon accounts for 0.03%, carbon dioxide accounts for 0.31%, and ammonia ...... The temperature is 26.22 degrees Celsius and the humidity is ......"

Xu Xiaoting's report was very skillful, and her words were very clear, and the squad leader Craven expressed his approval, and then he asked everyone: "Is there anything abnormal in the data?" ”

On the second basement floor of the subway station, the first floor is even darker, everyone is very nervous, instinctively, stuffed with all kinds of dangerous predictions in people's minds, invisibly, making people's thinking ability very weak. However, Bliss soon discovered anomalies in the data. "Hell, the concentration of carbon dioxide is too high, 30 times higher than in the normal atmosphere, Tang Meiren, are you sure the data is correct?"

Xu Xiaoting refreshed the data again and confirmed that it was correct.

"Will it poison people?" Raff asked, of course, it didn't make sense for him to ask the question, the robot would not be poisoned.

"This concentration, not yet." "[The CO2 concentration] has to be 3 percent, which is 10 times higher than it is now, to be able to poison people, but that's still weird...... It's only about 10 meters underground, but the concentration of carbon dioxide is like 30 meters underground......"

"It seems that the homework we did before we came was still effective." Craven complimented Briss and Casey, and at the same time, he turned his head to glare at Raff, who was clearly the kid who didn't do his homework.

"The signal strength here has started to drop." Xu Xiaoting said to everyone, "If we want to go deeper, then we have to extend the length of the cable now," she pointed not far away, where the end of the main cable is already connected, and at the end of the main cable, the last branch base station is connected. As described in the mission briefing, the survivability of the deployment of the last group of troops can only extend here.

"So, guys, let's get to work." Craven said in a slightly commanding tone.
