A bunch of keys were cleared out and placed in front of Xia Yunli, and there were even some strange small items inside. Xia Yunli took them together, and then guided the convoy to the coal mine and small power station next to Longyearbyen.

Longyearbyen's City is a city of miners founded in the early 20th century by the Boston Arctic Coal Company of the United States, destroyed by the war in 1943 and later rebuilt after the war. Mining has always been an important part of the city, with more than half of the city's residents employed by mining companies, and their lives revolve almost entirely around white snow and black coal.

On the other side of the hill near Longyearbyen, the Doomsday Seed Bank sits halfway up the mountain, and the power station is not far from the foothills, because the seed bank is located on the site of an abandoned coal mine, and the power station was built on the principle of proximity.

The power station, which supplies the city's electricity needs, has been out of service for a long time, and there is no black smoke visible above the power station or the roar of machinery inside. Several tall chimneys with red and white paint stand in the middle of a factory building, the top of which has been covered with snow.

The convoy went directly through the gate of the power station and entered inside, where there were more zombies, and Xu Yihang was curious that this extremely cold weather seemed to have no effect on them, except that the movement became relatively slow.

There were also a few zombies that fell to the ground because of the rain or ice and snow that froze into ice mounds, although some people in the convoy wondered if they still had the vitality to attack humans after thawing, but no one tried to verify this, and the soldiers also made up a few shots to the heads of those ice mounds when dealing with the zombies close to the convoy.

After searching the power station and eliminating all the visible dangers, the convoy finally stopped at the door of a factory building.

"That's it," Xia Yunli had previously checked the map inside the office at the entrance of the power station, and the building in front of him was the power transmission equipment room of the power station. "We alone can't get the power station back up and running in a short period of time, so we have to try to reserve power."

"Reserve power?" Xu Yihang didn't quite understand.

"Longyearbyen is built on a hill full of coal mines, and almost all of its residents work for mines and power stations, so this small town was built for mining. Nowadays, the 'Doomsday Seed Bank' is located here, and its importance is no less than the coal resources here, so the local government has prepared a reserve power supply on the basis of the power station, and these equipment is to reserve power for the power station and the Doomsday Seed Bank in case of emergency, after all, whether it is a town or a seed bank, their normal operation is inseparable from electricity. ”

"The energy stored in these reserve power sources is used to cope with special situations, so that it can be supported until it is back to work after an accident at the power station, for example." Xia Yunli continued, "What we need to do now is to restart this power storage device and restore the power inside the seed bank, because in addition to lighting and temperature control, there are five gates inside that need electricity to open. ”

"It feels complicated," Xu Yihang thought for a moment, becoming more and more curious about the situation in this seed bank.

Entering the power transmission equipment room of the power station, Xia Yunli began to look for the reserve power supply. This set of equipment was only known when he visited the 'Doomsday Seed Bank' with the group and listened to the introduction of the local management personnel, and now it comes in handy, of course, everyone can also break down the door violently, but in this way, the seeds stored in it are completely exposed, which is equivalent to indirectly destroying the hope of human beings to deal with natural disasters.

Coming out of the power station, everyone saw some bright lights appearing halfway up the mountain, and the reserve power supply had been turned on again, and at this moment Xia Yunli was sitting in the car and pointing to the place where the lights were turned on to tell everyone that it was the door of the "Doomsday Seed Bank".

"That's the gate? It looks like a rectangular box sticking out of the snow. Da Fei leaned over the car window and looked at the buildings on the mountainside in the distance, and asked with some curiosity, in his impression, the gate of this mysterious place should also be very magnificent.

"Didn't Professor Xia say before, the seed bank is built inside the mountain, and what you see there should only be the entrance to the seed bank passage, so it's not strange that it looks like a box." Chen Bin explained.

The convoy went up the mountain road, and the city of Longyearbyen, at the foot of the mountain, looked very hazy at night, and the city without lights was like a lifeless body, giving people a cold feeling. The light on the mountain is the direction of the convoy, but the mountain road is covered with ice and snow, and there is a lack of manual cleaning for a long time, and the road is blocked and long at the moment, and it is very difficult to walk.

In order to avoid unnecessary accidents, Xia Yunli asked the team to slow down and gradually move closer to the destination in the safest and safest way.

"Excited? Brother Zhang," Chen Bin asked at Zhang Dada.

"Excited, my hands are shaking," Zhang Dada grinned, "I don't know if there will be the answer I want here, those alien messages guide me here, I believe there is a providence in the dark." I'm not superstitious, but there are some things that are really magical, especially being exposed to a higher civilization, and I don't know how to describe it, because I have never had it before. ”

"Like first love?" Da Fei asked.

"Well, haha, of course your analogy isn't appropriate, but I can't think of a better analogy." Zhang Dada calmed down his excitement and took his thoughts back from the mountainside in the distance. The information he deciphered from the alien text was only one time and one coordinate, and there were no other clues, so whether or not he could make any new discoveries here in the future would directly determine the success or failure of the trip.

Zhang Dada was under a lot of pressure, because the government had invested huge manpower and material resources in his plan, and a team of nearly 100 people went with him to the polar regions and deserts thousands of miles away, just for a possible hope. This is a big gamble on the future of the country and the future of humanity.

"What do you see is that?" Da Fei suddenly pointed to a ribbon of colored light under the canopy and shouted in surprise.

"Aurora?" Chen Bin suddenly thought of the name.

"Yes, it's Aurora," Zhang Dada nodded, and the mood that had just calmed down became excited again.

At this time, Xia Yunli's voice also came from the communicator in the car, "Aurora has appeared in the sky in our northwest, and it is rare for everyone to observe it for a while." ”

"It would be nice to bring a camera," Da Fei wanted to take pictures of this strange natural landscape and bring it back to Chongming to show Chen Cailing, because the trip to the polar regions is too far away for ordinary people, and many people may not be able to set foot here in their lifetime, and the aurora is a rare sight, it is produced by the high-energy charged particle flow from the earth's magnetosphere or the sun that excites molecules or atoms in the upper atmosphere, and will not hang in the polar sky forever.

"Xiangrui, Brother Zhang, good signs," Chen Bin said.

"Accept your good words, brother." Zhang Dada's heart was hot, and he only felt that a warm blood was boiling in his chest.

The mountain road of more than half an hour made the convoy miserable, but fortunately, the destination was in front of them, and a rare polar natural landscape appeared in the sky at the right time - the aurora, which was the first time in the life of almost everyone in the convoy.

The door of the seed vault was covered in ice and snow, and while Xu Yihang and the others were cleaning the frost on the door, Xia Yunli began to find the one that could be unlocked from the pile of keys that he had dug out of the city hall building before. According to the keyhole on the door, Xia Yunli tried all the keys of the right size, and sure enough, one of them could open the door.

There was nothing special about the outermost iron gate, for there was nothing but lights and some exhaust pipes in the passage for a long time. When the person who enters the tunnel of more than 100 meters will find a blast-proof door, and after the explosion-proof door, there is a vestibule, from which you can lead to three more than 200 square meters of constant temperature warehouse, the warehouse uses air conditioning to maintain a constant temperature of -18 °C, and the surrounding walls are more than one meter thick of mud, these walls can not only keep warm, but also protect these warehouses from possible attacks from outside.

Because the power had just been restored, the temperature in the seed bank was not consistent with the outside, and it was not maintained at the original constant temperature of -18°C. When the group entered, the iron door was closed, and the lights in the tunnel were on, and the floor was a little slippery, and the walls were covered with snow-white frost.

Last summer, due to the continuous high temperature in the local area caused by the increase in snow melt and precipitation, the entrance of the tunnel was flooded with water, and the water ingress accident did not cause any substantial damage to the inside, the melting snow water poured into the location was not deep, and the temperature inside was maintained relatively well, so the water froze quickly after entering the tunnel, and there was no time to install waterproofing and drainage equipment inside, because the safety of the three deepest seed warehouses was not affected.

The tunnel was very quiet, only everyone's footsteps could be heard, and the people who entered it were all in awe, no one made a loud noise, everyone followed Xia Yunli and Zhang Dada quietly.

Zhang Dada walked slowly in the tunnel, and he kept looking around, not letting go of the walls and the ground. The only information deciphered from the alien text was the coordinates and a time, and he didn't know where the clues would appear in the seed vault.

The walls are recessed in an arc on both sides, with rocks in the mountains in some places and concrete in others, lighting fixtures on both sides and on top of the tunnels, and some pipes placed above the heads.

When he walked further inside, an explosion-proof door appeared on one side of the tunnel, Xia Yunli walked over and pressed the switch on the door, and the door with electricity turned on slowly opened.

Inside is the control and management room of the "Doomsday Seed Bank" and the room where the refrigeration equipment is placed, Xia Yunli has visited here, so he knows what they do.
