32 days

In the blink of an eye, from the brightly lit interior to the dark and cold primitive jungle, it is very similar to the mysterious transition of electrons that cannot be captured.

Yi Alan stood in the shadow of the trees, the swelling and pain in his ankle slightly stimulated his nerves, and he felt that the difference between the two worlds was getting bigger and bigger.After a while, the normal world has to wear down jackets to keep out the cold, and the 32nd is entering an increasingly hot summer.

It was too late to be sentimental, Yi Alan observed the stars from the gaps in the treetops, and after identifying the direction, he walked towards the agreed mountain.

After surveying in the normal world, the straight-line distance between him and Zhou Yan'an is not very far, less than ten kilometers. At Zhou Yan'an's rapid marching speed, he can cover it in one or two hours.However, the rugged mountain road and the obstruction of vegetation greatly restricted the speed.Maybe they won't meet until dawn.

At the same time, Liu Jinyue also set off.He dug out the flight suit he wore when he retired. The style and material had been outdated for a long time, but it had been maintained to be fairly new.When I put it on again, it looks a little out of shape, and the body of the elderly has been shrinking.

When Yi Alan walked out of a narrow valley in the twilight of the sky, the uniquely shaped mountain came into his field of vision clearly. He hopped on one foot and shook off all the dew on his clothes.

Going closer, Yi Alan seemed to be able to see a figure on the lower and gentler hill of the mountain.Is it Zhou Yan'an? He's here so soon.

There is a small creek beach with sparse trees - you can see the traces of wild animals trampled here. Before the 32nd, large beasts often came down from the mountain to drink here. For other small animals, this place may be taboo. land.When Yi Alan came to this flat land by stepping on the path of the beast, the figure on the top of the mountain also saw him and waved at him greatly.

Yi Alan jumped up and waved her hands in response, and then took out the binoculars to look over there. Zhou Yanan's appearance couldn't be more clear—standing, with a tall and straight silhouette, he should not have been injured during the crash.

Yi Alan was genuinely happy, laughed, and waved desperately.

Zhou Yan'an didn't wait for him at the foot of the mountain or come down to pick up Yi Alan, because the vegetation in the low-altitude area is tall and dense, and the visual field of vision is narrow, so it's easy to miss it if you don't pay attention.But Zhou Yanan was looking at Yi Alan, and Yi Alan could feel that his gaze was always following him, even when he entered the woods sometimes, and the intertwined canopy blocked the opponent's vision, but Zhou Yanan would capture that in the telescope. The fleeting blue shadows in the gaps in the trees, the slight reflections on the leaves of the shrubs being moved... These subtle movements, like the rare and beautiful shells scattered on the beach, are the proof of Yi Alan's existence .

When the sun's rays could clearly penetrate the leaves, Yi Alan finally reached the top.

The types and quantities of vegetation become rarer as we go up, mostly bare/exposed rocks, and the field of vision opens up. Zhou Yanan came to pick him up.

In the woods in the early morning, Yi Alan looked at Zhou Yan'an who jumped directly from a rock above, and smiled with relief, feeling relaxed all over, and an emotion called a sense of security wrapped him up.

Zhou Yanan: "Tired?"

Yi Alan: "Are you injured?"

Zhou Yanan shook her head.

Yi Alan panted lightly and said with a smile, "I'm fine too."

Zhou Yan'an first knelt down to look at his feet, then did not stand up, turned her back to him, and patted his shoulder: "The rest of the road is not easy to walk, I will carry you up."

Yi Alan was embarrassed: "No need, I'm so heavy..."

"You weigh?"

"More than 60 kilograms."

"It's really thin." Zhou Yan'an smiled, "When we used to practice forced marching with weights, the best results could reach your weight."

Yi Alan was still embarrassed, Zhou Yanan had no choice but to help him up.But Yi Alan is indeed stronger and stronger than he imagined, even if one of his feet is injured, his climbing figure can be regarded as vigorous.

Walking to the top of the mountain, the endless Qingyun Mountains came into view, Zhou Yan'an asked Yi Alan to sit down on the rock and showed him his feet.

Yi Alan's left ankle was swollen, and the skin was blue and purple. After all, he had traveled hard for more than ten hours.Zhou Yan'an took ointment from the tactical vest and applied it on him, and used the massage techniques learned in the military middle school to promote blood circulation and remove blood stasis.

This will hurt a little.

Zhou Yan'an talked to him: "When you climbed up, the sun just came out from the horizon."

"That's a pity," Yi Alan smiled palely, "I didn't get to see the sunrise."

"It's not a pity." Zhou Yan'an said in a normal but inexplicably magnetic voice, "You can imagine that the sun rises from the east and is in front of you. This mountain with a height of more than 1000 meters blocks a lot of sunlight, but the sun is constantly rising. As you rise higher, the shadow of the mountain recedes. Where you are about to go, the shadow is retreating, and where you walk, it gradually becomes brighter.”

Yi Alan couldn't imagine that scene at all, only felt her heart beating violently.The pain in the ankle turned into a burning fire, which could not kill him, but melted him into a puff of smoke, hot, ethereal and unreal.He longed for a gust of wind, a rain, to put his whole body into a cold embrace.

Yi Alan's mouth was dry, and he said with a mentality that he could not describe: "You must be very attractive to girls if you are so good at talking."

Zhou Yan'an looked up at him and said, "Most of the time, you can't get in touch with girls."

Yi Alan said in a daze, "Oh."

The noise of helicopter propellers stirred the peaceful mountains.

Zhou Yanan turned her head and squinted to see a small black dot that was gradually approaching.

The time was not too far off from their discussions.Zhou Yan'an put on Yi Alan's shoes and helped him stand up.

After such a short while, Zhou Yan'an suddenly asked Yi Alan, "Where did you meet Cheng Siyuan?"

Yi Alan was taken aback, and pointed to the direction where he came and drew a small circle: "Probably on those few mountains."

Zhou Yan'an looked there, nodded, and didn't ask any more questions.

Yi Alan looked at his profile and thought that Zhou Yan'an was just an ordinary person, and he shouldn't be infinitely greedy for the emotions Zhou Yan'an brought him.

After a while, the helicopter driven by Liu Jinyue came to the top of their heads, and the huge wind blew the sparse grass on the top of the mountain to lie down on the stone surface.

After Liu Jinyue adjusted the hovering position, a climbing rope hung down from the helicopter hatch.

Zhou Yan'an said to Yi Alan: "I really need to take you up this time."

Yi Alan had no choice but to nod, and lay on Zhou Yanan's back who was bent over.

"Hold me tight." Zhou Yanan said.

Yi Alan hugged him tightly.

Zhou Yanan clambered alternately with both hands, quickly and steadily climbed onto the helicopter along the rope.

The cabin is not big, and there are many things piled up in the back.

"Have you brought everything?" Zhou Yan'an put Yi Alan in the cabin, closed the door, and switched places with Liu Jinyue.Now it's up to him to drive.

Liu Jinyue smiled and said, "It's all set. Let's get ready to fight."

The helicopter flew to the R&D center.

An hour later, they saw the ground building of the R&D center on the edge of the mountains. Zhou Yanan did not land rashly on the airport runway. The granite square in front of the main building hall of the center lands.

The huge size of the helicopter can block the bullets flying from several of the best nearby sniper locations.

Zhou Yan'an told Yi Alan and Liu Jinyue to wait first. He got off the helicopter with a light machine gun in his hand, looked around, and then walked into the hall of the R&D center.

After a while, after confirming that there was no danger inside, he returned to the helicopter, followed Yi Alan and the other two, and took a backpack from Yi Alan at the same time.

Yi Alan stuffed the rectangular unknown instrument he had been carrying into the pocket of his tactical vest, and walked in the middle carrying a bucket of at least two liters of blue liquid, while Liu Jinyue also held a light machine gun in the rear.

There was silence, only the footsteps of the three of them, and no one dared to relax their vigilance.In such a large complex building deep underground and close to the mountains, it is necessary to be very cautious to prevent a sneak attack by a mysterious guy.

Zhou Yan'an is very familiar with the labyrinth-like building structure of the R&D center. He almost engraved the original construction drawings in his mind, and remembered the real purpose of each room in the R&D center during this month's training.

They walked cautiously all the way to the huge main control room on the basement floor.The main control room is divided into several rooms, namely the monitoring room, the electrical distribution room, the ventilation system control room, etc. This is the key to the normal operation of the building and for people to live.

The monitoring room was destroyed without accident, and it was impossible to see who the mysterious spy was and whether he was still inside the R&D center based on the monitoring.Yi Alan checked and thought that the electronic screen and related lines were damaged, but the monitoring system covering the entire public area of ​​the R&D center was actually quite complete.This means that maybe the mysterious spy may have other ways to monitor the actions of the three of them.

Zhou Yanan put down the backpack and took out three sets of protective clothing and a gas mask from it.The shape of the gas mask is slightly different from the styles circulated outside. I don't know if it is a relatively new invention.This was also brought by Liu Jinyue from outside by helicopter.

After changing into protective clothing and gas masks, they went to the control room of the ventilation system, where all the equipment was complete and still operating normally, including the surveillance camera on the ceiling.

Yi Alan nodded to Zhou Yan'an, and Zhou Yan'an picked up the bucket of blue liquid, violently opened the large round air filter with a machine gun, and destroyed the filter device inside, and then poured the bucket of blue liquid into the air. in the filter.Once the liquid was poured out, it quickly evaporated into a colorless gas, passed through the failed filter device, and was sent to every corner of the R&D center by the ventilation duct.

The blue liquid is the liquefied state of highly toxic chemicals, and such a bucket is enough for the R&D center to have no dead ends.

As a confidential research and development center, it can naturally switch to a wartime state at any time.When building this building, it was considered that the enemy would release biological and chemical weapons and destroy the filter device, so a large number of detectors were distributed in the ventilation ducts. Once toxic gases were detected, an alarm signal would be issued and the air circulation would be cut off.

However, Yi Alan has already hacked into the ventilation system network at this moment and forcibly turned off those detectors.

Of course, this was also taken into consideration when it was built, so there are several safe rooms on each floor underground, which are independent of the main control system.Personnel can go to the safe room to take refuge, and manually close the air flow inlet from the inside, and then use oxygen cylinders and small oxygen regeneration devices to tide over the difficulties and wait for rescue.

If the spy is still in the R&D center and sees this scene, he must go to the safe room to hide, but this can only be delayed for a while.The three of Zhou Yanan will check layer by layer, and they will eventually find him; or he is also looking for a set of gas masks in the R&D center, but if he can see Zhou Yanan, he will know that their gas masks are different from the spare ones in the R&D center , Maybe the conventional gas mask doesn't work on the mysterious blue liquid that Zhou Yanan brought.

Although biological and chemical weapons have been strongly condemned internationally, they are just like nuclear weapons. You can resolutely not use them, but you have to study them.Who knows what breakthroughs the country has made in this area. After all, this is only the Air Force weapons and equipment research and development center, far away from the biochemical field, and the news is not circulated.

If the mysterious spy doesn't want to put himself at risk, it's time to act.

Sure enough, after 5 minutes, a mechanical male voice came out of nowhere: "Press 1 to talk to me."

The source of the sound is a radio walkie-talkie.

Zhou Yan'an walked over, picked up the walkie-talkie, and pressed the No. 1 button, and the walkie-talkie switched to a shortcut channel that had already been set.

The other party should have used a voice changer, and his voice was stiff and cold: "What are you throwing?"

Zhou Yan'an looked at the camera, as if talking face-to-face with that person: "I don't know, I only know that it is highly poisonous."

"Are the gas masks here useful?"

"I don't know either, you can try it."

The voice fell silent, and said after a while, "Are you still concerned about Cheng Sisi's life?"

Zhou Yanan said, "Of course."

"That's good." The voice smiled indifferently, "I'll give Cheng Sisi to you, and as a deal, you have to give me a set of gas masks like yours, and tell me the biggest secret of this research and development center."

"What secret?"

"Don't play dumb, Plan S."

The three of Zhou Yan'an looked at each other, and it turned out that the other party came for Project S.

Zhou Yanan said: "I don't know the specific content of Plan S."

"Lies," the voice said sarcastically.

"I'm not lying, I really don't know." Zhou Yan'an said, "But my companion knows. To be precise, he has the opportunity to know that he can enter the network system of Plan S."

"Okay, then let him tell me." This person should have seen how Yi Alan hacked into the ventilation system and turned off the detector just now.

"But we want to see Cheng Sisi."

"You'll see."

"If we don't see Cheng Sisi, we won't make any deal with you."

The voice said: "Cheng Sisi is not here. My people don't know how to fly a plane. I'm afraid I won't be able to send her here in a short time."

Zhou Yan'an then said: "Then tell me her address, and I'll pick her up. My companion stays here."

"and then?"

"Then my partner confirms that I have received Cheng Sisi, and will tell you the details of Plan S."

"What if he won't?"

"No. His safety is in your hands. In fact, you just changed the hostage from Cheng Sisi to him. You have nothing to lose."
