System into the end of the world

Chapter 159

The arrival of the helicopter attracted a large number of zombies to gather downstairs. Yu Nan got off the plane, stood on the edge of the roof, looked down, and quickly shrank back.Now they landed directly on the roof of a ten-story building in the center of Hohhot, and there is still a certain distance from the officers and soldiers who are performing missions on the periphery, so there is no need to worry about accidental injuries later.

"Don't look, hurry up and help." Zhan Xuyang shouted from the side of the plane.

"Here, here, what do you want? Remote control aircraft, right?" Yu Nan trotted back and opened the mall to find a suitable remote control spraying aircraft. "Mu Dong, my laptop is on the seat, you go and get it off, and turn on the monitor." She said while looking for it.Mu Dong agreed, and went to get the computer on the plane.

After buying everything, take it out.Yu Nan and Zhan Xuyang were busy refueling, and the other was mixing the potion, "Are you ready?" Yu Nan turned to ask after finishing refueling.

"It's over." Zhan Xuyang poured the potion into the water tank, bent down to get the remote control on the ground.He remotely controlled the plane to take off, and flew downstairs in a counterclockwise circle.Mu Dong took a notebook and sat next to them, the images on the screen were chasing the trajectory of the plane, her gaze was fixed on the screen, and she adjusted the distance from time to time so that they could see more clearly.

When it was four or five meters above the ground, the plane stopped descending and started spraying the medicine.It just so happened that these zombies were all gathered together, and as soon as the potion was dispersed, they were sprayed right on the spot.

Yu Nan's eyes closely followed the plane on the screen, seeing all the zombies sprayed with the potion dry up at a slow speed, her face turned red with excitement, "Great! It's really effective."

"Wait and see." Zhan Xuyang was more calm than her, and his gaze also fell on the screen. "Keep your eyes up a bit," he said.

Mu Dong did as he said.

After a few minutes, shriveled zombies began to lose their ability to move one after another, and fell straight to the ground.Yu Nan looked at Zhan Xuyang silently, waiting for him to speak.

Zhan Xuyang squinted his eyes for a while, and controlled the plane to expand the spraying range, "The potion doesn't work immediately, maybe it has to wait for the potion to penetrate, or maybe it has to wait for the particles in the water to dry up. Add water, It may be just to make the agent adhere to a larger surface. And spraying it once is not enough, and it needs to be sprayed several times, so it can be seen that this agent can only be used at high altitudes. If it is really face to face, there is no time to wait for it to take effect."

Listening to his words, Yu Nan suddenly felt that something was wrong.

"Since it is useful, why are there still zombies in country M?" Mu Dong said suddenly.

"That's right!" Yu Nan finally knew what was going on with this sense of disobedience. If it wasn't publicized, it was to take the lead in this tug-of-war with the zombies, so why did the zombies in country M also The same is not wiped clean? "Isn't there... any side effects?" She frowned and muttered.However, this is not stated in the description of the mall.

Zhan Xuyang's hands controlling the remote control station paused, and one of them didn't pay attention. The plane slammed into the opposite building, and then fell to the ground.

"..." Yu Nan withdrew his gaze, stuck out his tongue, and said nonchalantly, "Let's go, take the desiccant to the Institute of Biology for testing after we go back."

"Yeah." Zhan Xuyang stood on the edge of the building and observed for a while, then turned around and took a few steps to wrap his arms around Yu Nan's waist, and boarded the plane one after the other.Mu Dong put away his notebook and followed, started the plane and left.

When we returned to the base, it was just in time for dinner, and soldiers in twos and threes walked to the cafeteria together.In Xingcheng, Zhan Xuyang didn't require the soldiers to perform the routines in the Z country's troops, such as eating together and singing military songs.Soldiers in Star City are also a profession. They must obey all orders when they go to get off work, and they can move around as they please after work.Of course, if there are special circumstances, there is also an emergency call back.

"Old Zhan, Yu Nan."

Zhan Xuyang and Yu Nan followed the sound and looked over, but they didn't see anyone.

"Here, upstairs." They saw Sun Yanguang who was waving to them upstairs in the Chinese medicine hall. "Come up and show you the results of this time."

"Let's go, go and see, are you hungry?" Zhan Xuyang turned his head and asked her.

"It's okay." Yu Nan was led into the hospital by his hand.

"Brother Zhan, sister-in-law." Sun Yanbin from the branch of the Sun family came up to greet them when he saw them, "Brother Guang is on the third floor."

"Okay, thank you." Zhan Xuyang nodded to him, and walked upstairs without stopping.

"Come on, come up quickly." Still on the stairs, I heard Sun Yanguang's voice.

"What do you want to show us? Have you eaten yet?" The two walked into Sun Yanguang's consulting room.

"I haven't eaten yet, let's go to the foreign affairs area to eat together later." Sun Yanguang took out a glass bottle and two pages of paper from the cabinet next to the wall, "Look at this, this is the potion you asked me to mix last time. Here is the comparative analysis report of ingredients."

Yu Nan was stunned for a moment, then vaguely remembered about the recovery fluid.With no news for such a long time, she thought it was over, otherwise she wouldn't have to rush to dump this matter on Geng Zhou and Mu Dong again.

"Is there a result?" Zhan Xuyang ignored the potion and picked up the report directly to read it.

"It's too much effort. Hey, come to think of it, what are you using this thing for? It can't be for drinking, right?" Sun Yanguang took a cup and gave them two cups of tea.

"Of course not." Zhan Xuyang laughed, "It seems that the ingredients are not too different, but I don't know how the effect will be. Can this kind of potion help me prepare more?" He asked.

"Yes, how much?"

"3 tons, make a list of what materials you need, and I'll get back to you." Zhan Xuyang put down the report and said. 3 tons is exactly the amount of a box of potions.

"No problem, wait for me." Sun Yanguang walked into the inner room, not long after, when he came out again, he handed a list to Zhan Xuyang, "The dosage and medicinal materials are all written on it."

Zhan Xuyang didn't even look at it, and directly handed it to Yu Nan. "I will prepare medicinal materials for you when I go back in the afternoon. How long will it take to make it?"

"It will take a week at the fastest, and I have to process it after I get it back, which is troublesome." Sun Yanguang replied.

Zhan Xuyang nodded, "It will be ready for you in the afternoon, wait for my call."

Sun Yanguang made an "OK" gesture, and looked at the time displayed on the clock on the table, "Come on, let's go to eat, a *** restaurant has just opened in the foreign affairs area, let's go to eat roast leg of lamb."

When they went out, they called a few acquaintances, and the group went to the restaurant in a mighty manner.

Considering that there is still work in the afternoon, there is no drink on the table.Chatted about each other's current situation, and talked about the situation outside the city.After dinner, Yu Nan and Zhan Xuyang turned around and went to the Institute of Biology to send the desiccant there for testing.

"Do you have anything to do in the afternoon? If you have nothing to do, go home and rest." Walking in front of the city hall, Zhan Xuyang stopped and asked.

"Aren't you going to prepare medicinal materials for Sun Yanguang?" Yu Nan replied.

"Well, then you go, let Mu Dong send me a trip after preparations, and then you go home and rest for a while."

"What about you?"

Zhan Xuyang shrugged, "I still have a lot of get off work to do, and I don't know if I can get off work on time."

"Okay, don't be too tired, take some time to rest." Waved goodbye to him, Yu Nan left first.

After returning home, he prepared the medicinal materials that Sun Yanguang needed, and asked Mu Dong to deliver them, and Yu Nan climbed into bed and fell asleep.After only sleeping for 2 hours, I woke up. As soon as I walked out the door, I found that the protective cover above my head was open.

Thinking it was another ordinary small-scale attack, she didn't take it seriously at all, but walked towards the greenhouse.

"Master Yu." Several soldiers who were about to leave after being treated stopped and saluted her.

"Hey, just right, do you have anything to do? If you have nothing to do, come and help me." Yu Nan greeted.The fruits in the shed had ripened a lot, and if they were not picked, they would rot on the trees, so she planned to pick them and send them to the cafeteria, as an after-dinner fruit for the soldiers.

"We just received an order to gather and stand by in case of an attack." The lieutenant with the highest rank among them replied.

"Oh, then you guys go first." Yu Nan waved them away.After turning around and thinking about it, I found the problem: usually the wounded will not go to the battlefield, and even these wounded who came to receive treatment did not receive training and tasks again until the day after their injuries.And now such a hasty call for the soldiers who had just been healed, obviously something happened. "Wait, what hit the base this time?"

"I don't know the details, I heard it's a kind of bug."

"Yeah." Yu Nan nodded, seeing that they were in a hurry, she let them go first.She stood at the door of the greenhouse and thought for a while, then decided to go and see for herself.Tangyuan just came back from somewhere, and when she saw her, she rushed over immediately. "Hey, play at home by yourself." After stroking the top of its head, Yu Nan hurried out.While walking, he called Zhan Xuyang to inquire about the situation.

"...the molluscs in the water are black and gray, three to forty centimeters long, and there are a lot of them. Don't come here again. You can't get out even if the protective cover is on. These insects are still outside the city. What about?" Zhan Xuyang said on the phone.

After the protective cover was opened, it was impossible to enter and exit. After discovering this drawback, except for covering the entire Star City when it was opened for the first time, it was later controlled in the city center area and the City Hall area.Once attacked, ordinary citizens will quickly evacuate here to hide, while soldiers and combatants are fighting outside. When it is confirmed that it is safe, when will the protective cover be closed.

Sure enough, Yu Nan was stopped by the protective shield before he went far.Many citizens moved benches and sat on the square in front of the city hall, waiting for the protective shield to close.

"City Lord Yu." The dozen or so soldiers who had gathered here before were standing in a straight line.Outside the protective cover, soldiers could be seen carrying boxes of things out.

Yu Nan waved his hand, "You are busy, don't worry about me."

"Yes!" The lieutenant saluted and returned to the team.

What Zhan Xuyang said was right, she really couldn't get out, after walking a few steps in place, she turned her head and walked back.Feeling slow, he trotted again.Back home, turn on the computer, and pull the satellite image over Star City.Just one glance, almost made her spit out the overnight meal.Those bugs were thin and long, and they spread densely across the ground from the lakeside to the city wall, occasionally mixed with a few huge zombie crabs and other aquatic products, rushing towards the place exuding the breath of living people.

Zhan Xuyang hung up the phone here, silently watching the battle situation below the city wall.Beside him, apart from Congdong and the others, there were dozens of people with abilities throwing abilities down, especially those giant zombie aquatic creatures mixed among the bugs, which were the focus of their attacks.

A team of soldiers wore gas masks and burned the bugs with a blowtorch. Under the high temperature, these bugs were quickly burned to black ash, emitting a disgusting stench.

Fuel tanks are constantly being delivered from the rear. Before the fuel is exhausted, a new team of soldiers will replace them to ensure everyone's safety.

"Where do so many bugs come from?" Cong Dong said with a frown.

"In the water." Bai Qi said, staring at an insect that looked like a dragonfly larva rushing towards him from a distance.

"Of course I know it came from the water, but the question is, were there so many bugs in the water before?" Cong Dong asked.

"It's not surprising that there are worms in the water, but the strange thing is that these worms look like marine zombie creatures that have been sprayed with medicine." Zhan Xuyang said, "Has country R sprayed medicine later? It can even affect the creatures in the star sea , it's really weird."

The drug spread from the territorial sea of ​​country R to the star sea. Not only is the gap between the ocean and the inland lake, but also a distance of 2000 kilometers. How did this happen?Besides, the purification ability of the Elf Tree King is not fake. Even if there is medicine, it should lose its effect, so the origin of these bugs is very problematic.

"No, the medicine was sprayed once." Cong Dong shook his head and said.

"Maybe it's the effect of nuclear bomb radiation?" White guessed.

Probably not.Zhan Xuyang shook his head and didn't speak. His reasons were not suitable for speaking directly.The elf tree also has the effect of preventing radiation. When the zombies in other places began to transform towards the fourth and fifth levels, even the third-level zombies were rarely seen near Xinghai.Of course, after the clean-up operation started, there were basically no zombies to be seen. "Maybe there is an underground river at the bottom of the lake, and these bugs came from other places." He guessed.

Congdong pondered for a moment, then nodded, "Maybe there is such a possibility, but it will be troublesome, who knows how many such bugs are left, and when will they be killed? These bugs can come endlessly." , we humans can't stand it."

"There is no way, we can only send someone to clean it up slowly. If we use a protective cover to buckle up, if these bugs don't disperse, we won't be able to get out." Zhan Xuyang paused, "Divide into a few more teams, work in shifts, try to Let them rest for a while each time. Persevere for a while and see, if there are still no fewer bugs by tomorrow morning, close the protective cover, and I will ask Yu Nan to come out and plant a few plants to try."

"Okay." Cong Dong nodded.
