Zhan Yun smiled inexplicably, and did not directly answer Qian Fugui's question, but brought up an irrelevant topic, "Have you noticed that it has been windy these two days."
"Yeah, could it be that autumn is finally coming? Haha." Qian Fugui knew how to read words and expressions, and knew what to ask and what not to ask, so he continued on the topic of Zhanyun.
"No, winter is coming." Zhan Yun said with a serious face, which is actually the reason why they are in a hurry to find level 4 zombies now.
After the outbreak of the end of the world, people spend every day in a high temperature of more than 40 degrees. Even at night, the temperature often reaches more than 35 degrees. The long-term scorching heat has led to severe drought and the death of a large number of plants. It's hard to see green anymore. But in the past few days, a sudden wind has blown up, which has caused the temperature to drop slightly, so people have begun to speculate whether the season will finally change, and some people are very happy that the weather is finally cool.
However, Zhan Yun and Su Ruizhe knew very well that this was a harbinger of the coming winter. The weather in the last days is very bad. There are only two seasons, cold and summer. Spring and autumn seem to have disappeared from this world. They are not as optimistic as ordinary people. They know that the arrival of this winter is not a good thing for human beings. In fact, cold winter is more harmful to human survival than scorching heat.
In Su Ruizhe's memory, the winter in the last days was really extremely cold, the temperature was minus 30 degrees, and if he didn't take protective measures, he would be frozen into a popsicle within ten minutes. But because when the end of the world broke out, it was summer, and then it was always in the scorching heat. People didn't have the consciousness to prepare things for winter, so many people died in the first winter after the end of the world broke out.
Zombies who are living dead are not afraid of the severe cold at all, and still follow their instincts to find food. High-level zombies can control zombies lower than themselves, so in the cold winter season, zombies are more likely to besiege the city.
In Su Ruizhe's memory, a base was destroyed just this winter. It's just that when Su Ruizhe heard this matter mentioned, it was already a few years after the end of the world, and that base had been destroyed for several years. No one remembers the name of that base, only that hundreds of thousands of people died at that time , and it was a level 4 zombie that caused all this.
A zombie that can reach level 4 in the early days of the end of the world is definitely comparable to a zombie king. After that base was destroyed, this zombie directly evolved to level 5 and launched a large wave of zombies to attack the next base.
All major bases felt a great sense of crisis, and urgently mobilized many powerful supernatural beings to rescue them, but they all died in vain. In the end, it was the capital base that used weapons of mass destruction to razed the zombie and the city to the ground together, and the number of people who died in that battle was countless.
After being reborn, Su Ruizhe had been thinking about this matter all the time. When he came back from his rebirth, his ability had already reached the early stage of the third level. After this period of accumulation, he had vaguely touched the threshold of the fourth level. He felt that together with Zhan Yun and the others, he might already have the ability to fight that fourth-level zombie.
That's why they asked Qian Fugui to find out about the fourth-level zombie. They had to kill the fourth-level zombie as soon as possible to avoid a series of tragedies. The crystal nucleus of that fourth-level zombie can also be used to upgrade Su Ruizhe.
"Winter, it seems that I should stock up some winter things." Qian Fugui touched Yuanyuan's chin and said, without doubting Zhanyun's judgment at all.
"Okay, when you get something good, remember to keep it for us."
"No problem, no problem." Qian Fugui readily agreed.
At this moment, they suddenly heard the sound of sirens in the base.
Zhan Yun frowned when he heard the sound, he didn't know what happened at the base.
He immediately got up and walked out. Su Ruizhe took out two antidotes and handed them to Qian Fugui, and then followed. This was the reward they had negotiated from the beginning. Antidotes and supernatural potion bases are sold in limited quantities, but for Zhan Yun and the others, they are easy to get.
"Thank you very much." Qian Fugui put the things away carefully, and watched Zhanyun and the others leave.
Zheng Jiahe and Yu Dongdong were holding the watermelon in their hands and were eating half of it. Seeing that Zhanyun and the others were leaving, they quickly swallowed the melon in two mouthfuls, and then ran out. Cheng Jiao and Wu Jing, who were carrying things outside, saw them coming out, and immediately put down their things and followed.
A group of people quickly ran towards the direction where the siren sounded, and met Xu Sihan and Zhao Bing on the way. After Zhao Bing and his team came to the southern base, they were merged into the law enforcement brigade, responsible for the internal security of the base, and were under the jurisdiction of Xu Sihan.
"What happened?" Zhan Yun asked after nodding to Xu Sihan and Zhao Bing.
"It should be the research center." Xu Sihan said with a serious expression, which would trigger an alarm at the entire base level, only the research center and the base warehouse, and the direction of the sound should be the location of the research center.
Hearing this, everyone immediately quickened their pace. The research center is the most heavily guarded place in the southern base. After all, the formulas and finished products of antidotes and supernatural medicines are all in the research center. Once there is a problem there, it will have a very adverse impact on the base.
They quickly arrived at the base headquarters, swiped their ID cards, and entered the headquarters building. Then he took the internal elevator down to the second basement floor, passed through two security gates, and passed biometric identification to the outside of the research center.
Because the alarm device was triggered, the research center is now fully enclosed, all passages and gates have been closed, Jiang Xuzhou is leading hundreds of heavily armed soldiers to surround the periphery of the research center, he saw Zhan Yun and Xu Sihan After coming together, he immediately waved to them.
Zhan Yun and Su Ruizhe immediately stepped forward and asked, "Commander Jiang, what's the situation now?"
"Someone has invaded the research center. Although no abnormalities were found in the monitoring, the infrared siren was triggered." Jiang Xuzhou continued after a pause, "I suspect it is a person who can be invisible."
Zhan Yun nodded approvingly, "Is there any solution now?"
Jiang Xuzhou nodded, "After the alarm was triggered, the defense system was automatically activated, and the gates of all rooms and passages in the research center have been closed. That person must be locked in. I have sent someone to get the thermal imager and The nebulizers are coming and should be able to find the man shortly."
"That's good."
Soon, a thermal imaging camera and a nebulizer were brought in. The thermal imaging camera can scan a designated area from a certain distance. Even if the person can hide, he will still be exposed under the thermal imaging camera. After locking the room where the target is located, add some powder directly to the sprayer and spray it in the room to make the invisible man invisible.
Using two prongs, they quickly found the place where the person was hiding. This person was very unlucky. He probably followed the researchers or base staff all the way into the research center in stealth, but there was a hidden infrared ray at the entrance of the research center. For the alarm device, one person's card was swiped, but two people entered, and the alarm was triggered immediately. The gates of all rooms and passages were immediately closed, so this person was locked in the outermost corridor of the research center, scurrying around like ants on a hot pot.
Through the ventilation unit, they blew the powder from the sprayer into the aisle, and the white powder quickly outlined the shape of a person in the air.
That person also realized that he had been exposed, so he simply lifted his invisibility, pulled up the staff member who was lying in the corner, and held an oval grenade in his hand. The safety pin of the grenade had been pulled out, and his thumb was firmly pressed on the trigger handle. Once released, the grenade would explode.
"Let me out! Or I'll detonate the grenade! You and this research center will all be buried with me!" the man shouted loudly, his eyes widened with excitement.
The staff member he grabbed and stood in front of him was probably the person he followed all the way. After the alarm sounded, he knocked that person unconscious, and now he is taking him as a hostage.
The staff member kept his head down because he was in a coma, and couldn't see clearly. Now he was dragged in front of him, and everyone realized that it was actually Dr. Yang!
Regardless of whether it was for the life of Dr. Yang, or for the safety of the important information in the research center and the lives of dozens of people, this person should not be allowed to detonate the grenade.
Jiang Xuzhou gritted his teeth and ordered, "Everyone step back, open the door..."
The gate at the entrance of the research center was finally opened. With a triumphant smile on his face, the man held Dr. Yang in a coma and walked towards the gate step by step.
Just as he was about to walk out of the research center, a hand appeared out of nowhere and suddenly grabbed his left hand holding the grenade.
The man turned pale with shock, let go of Dr. Yang, and wanted to use his right hand to break away the inexplicably appearing hand.
With two bangs, he was shot in his right hand and left leg, and he fell down screaming, but his left hand was firmly held down by the hand that appeared out of nowhere.
Su Ruizhe trotted forward, took out a handful of nuts from his pocket, condensed it into a huge nut, and then slowly transformed it into a square explosion-proof box, which is a tool often used by bomb disposal teams , which can contain explosives in boxes.
The grenade exploded immediately in the explosion-proof box, but did not cause any adverse consequences.
Jiang Xuzhou beckoned, and a soldier immediately stepped forward, washed off the powder on the face of the man on the ground with water, then took out his camera, and took a picture of his face, planning to search the system to see if he could The identity of this person could not be found.
