There is an old saying: "He who has not worked hard will never understand the preciousness of every grain of grain." In the same way, people who have not lived in the dark world will naturally not be able to understand the hardships and fears experienced by hunters.

The day of the sun, for every human being who survives the war, means things and happiness. Only on solar days can you not have to consume precious fuel. Only on the day of the sun can you get out of your own corner and enjoy the happiness of being a human being. In the same way, it is only on the day of the sun that you can get the most and the most enough food to fill your stomach. Bugs fear the sun, just as the devil fears angels. This is common sense that all hunters understand. However, the gap between understanding and exploiting is too great. After all, the sun only appears for a measly few hours at a time. If you want to wait until it reappears, the interval between them will take dozens of times the same amount of time. And darkness, for suffering human beings, simply means the most terrible death.

Such threats and nightmares will never be seen again. Because, from this moment on, the light of the sun will continue to shine on the earth forever. The "Umbrella" has been closed. The era of warm sunshine has come. However, this also means that from now on, all hunters, except for those bugs that can withstand warm climates, will no longer be able to get any food from nature.

The celebration lasted for three days before it was forcibly stopped by the administrators. It's not that they don't want to see such a happy scene. It's because of the harsh reality that they have been facing since then, and they must keep a clear head at all times. This is the biggest difference between the rulers and the poor. The atmosphere of the celebration is good, but to do so is also to consume a lot of food. This is undoubtedly an unnecessary waste for the next few years when there will be no harvest and no land. Therefore. After announcing the relevant food rationing order, all the dragons began to slowly wake up from their initial joy and return to their busy and happy work. "The food rationing system must be resolutely enforced." In the spacious conference hall of Dragon City, Tianxiang looked cold and said to all the participants: "No one can be an exception. From today onwards, the implementation of specific plans will be the responsibility of the individual city administrations. As for the supervisory side, it is entrusted to the military. The Secret Service will set up a large number of law enforcement teams to find any manager to engage in illegal possession or corruption, if there is credible evidence. It can be killed without approval. The most resolute means must be used. Let the whole family smoothly survive the period of food scarcity. "The order was carried out without reservation in the shortest possible time. This hectic scene is not limited to the hinterland cities of the Dragons. In fact, compared to the tense and somewhat mysterious northern border, the city is too relaxed because of the relatively busy situation.

The foundation of the newly built fortress has been laid, and a large amount of mixed reinforced concrete has been poured on the hard foundation under the transportation of engineering trucks and in the direction specified in the drawings. Although the closure of the "Umbrella" has filled the air with a warm smell again, it is already winter after all. The biting cold that permeates the wind. Makes it difficult to dispel any warmth. The work schedule is too tight. Tianxiang left only three months for the construction of the northern fortress. This does not include the natural solidification and hardening of cement. In the words of the fortress designer: "This is simply an impossible task." ”

"I know you can't do it within the allotted time, but the work must be done. I don't care what method you use, anyway, three months later, on the northernmost border of sexually Beijing. A well-fortified fortress must be erected. These are the words of Tianxiang when he met with the people who asked for an extension of the construction period. Although it sounds a little untouchable, Tianxiang understands that there is not much time left for him. Three months, this is already the maximum limit I can give. The consequences of closing the "umbrella" are quite serious. In less than half a month, the "insect mountains" built artificially around all the central cities, as well as the "insect circles" for raising carnivorous insects, have already appeared abnormally on the first day when the sun returns to the earth. Fearful of light and temperature, the bugs have retreated back into the deepest part of the earth, and the sudden climate has made it impossible for them to adapt. After a week, more than fifty percent of all the insects that were raised had died, and the rest were already showing obvious signs of physical weakening. It doesn't seem long before they follow in the footsteps of their own kind. Before the sun was released, the managers of all places had already followed the orders of Dragon City, except for a very small number of insects left for observation and breeding, the rest were all slaughtered and frozen in advance. It's just that no one thought that the change in climate would cause so much harm to these poor little guys. The same is true for insects, and the situation for plants is not much better. Although they are not as pronounced as insects, the pace of death is getting closer and closer from the shrunken leaves and yellowed branches. In particular, the tubers, which are buried deep in the ground and become the main daily food of the dragons, are also slowly shedding their leaves in the aboveground parts. The roots, which were supposed to be thick from the ground, were either rotten or had already turned into a puddle of disgusting yellow water.

Warmth, sunshine, these terms that once represented beautiful meanings in ancient books, are now the biggest killers of all living creatures in the dark world. Of course, not all animals and plants are afraid of sunlight. There are also a very small number of drought-tolerant and temperature-loving insects and plants, which show vigorous vitality on the first day of closing the "umbrella". It's just that there are too few of them. The specific value that can be used in it has not yet been fully revealed. Both the No. 1 and No. 2 sites have a considerable area of underground greenhouses. There, a large number of food crops can be cultivated using ancient liquid cultivation methods. Rice, wheat, and corn, which were once commonly eaten in ancient times, continue to play their due role here. According to calculations, the ancient food crops cultivated in the greenhouses of the two bases were enough to supply the consumption of more than 30,000 people. However, for a large ethnic group with a population of more than millions, it is just a grain of leftovers between the teeth. Similar artificial greenhouses have been built in Dragon City. However, since the preparation time was mainly used to collect food and build warehouses, the hunters simply did not have time to conduct relevant liquid cultivation research. In addition, the construction of fortresses on the northern border has drawn a large number of manpower and material resources. Therefore, the range of greenhouses in the city has always been maintained in a small area. The amount of food available is only enough to feed a few thousand people. Not all of them are busy. The children in the group are obviously much luckier than the adults. Not only are they able to be exposed to the warm sunlight every day, but they are also free to play freely in a sunny environment. For them, the darkness has already served past. Tomorrow will be a world full of infinite light.

Of course, the prerequisite for all this must be peace, complete peace. Regarding the warning of the sea clan, Tianxiang was not careless at all. On the day he returned to Dragon City from the bottom of the sea, he quickly checked the latest satellite pictures. It turned out that behind the mountains near the desert on the northern border, there seemed to be patches of inexplicable cover like black mist.

The topography of the world has changed much more than it did 600 years ago. The frequent use of earthquake tactics not only brought unexpected opportunities for users to win, but also laid the groundwork for the violent movement of the earth's crust. Man-made underground explosions brought rivers of magma that had been hidden underground out of the ground, and after spurting and flashing, new mountains were formed. After hundreds of years, new protrusions were formed that could not be found on a map before. At first glance, the black fog difficulty is nothing more than some kind of obstacle floating in the atmosphere. But when the photo is magnified dozens or hundreds of times, it also clearly shows small protrusions in the shape of round grains. It looked like a group of black ants clustered together and swarming towards the south.

The magnification of the photo has an insurmountable degree. Able to scale up to this point. Already the limit of the space technology department of the dragons. After all, it was a weather satellite that was launched 600 years ago that could still capture such images with its old terrestrial camera. It's not easy." I need a clearer picture. High-altitude light reconnaissance planes were dispatched to conduct strict observation of the area where the target was located. I had to see what was in the picture. ”

This is Tianxiang's new request to the observation department after being disappointed again. It was at this time that he gave the order for the construction of a new fortress. It's just that what he never dreamed of was that the high-altitude reconnaissance plane sent out never came back after it set off that day. In some respects, the flying aviation skills mastered by the dragons are probably far inferior to similar works made by the ancients 600 years ago. But in any case, a machine that can fly into the sky is quite powerful in itself. What's more, this is the first human-made aircraft that appeared after the extinction of civilization. Since it is a high-altitude reconnaissance aircraft, as the name suggests, the ascent of 20,000 meters is already its limit. At the beginning of the design of this aircraft, Tianxiang repeatedly asked Qin Guangduo to consider the speed and safety of the aircraft itself. Therefore, the main manufacturing advantages of the aircraft are also concentrated in speed and flight stability. As for the maximum ceiling of more than 20,000 meters, it was not within Qin Guang's consideration. After all, apart from the dragons, there is no other hunting group in this dark world, and they have the same level of technology as themselves. A group of hunters still using their guns and steel spears will never pose any threat even if it is a helicopter with an altitude of only a few hundred meters. However, the change of events is so unacceptable. A high-altitude reconnaissance plane with excellent performance disappeared without a trace in this way. Such a thing is obviously unacceptable.

What happened to the plane? Was it because of the weather conditions that had to make a forced landing? Or is it because magnetoelectric particles in the clouds have caused damage to its navigation instruments? Or, by mistake, did you stumble into something that could fly? Caused an accident on the plane? Everyone is speculating. Everyone thinks the same way. It was at this time that the order from the Supreme Commander made all their nervous minds return to the busyness of reality at that moment.

Send another reconnaissance plane. The flight path is exactly the same as previously arranged. That's right! The same blunder. It is absolutely impossible to happen twice. With this sobriety and anxiety of trying to find out the truth of the matter, the air command redispatched another reconnaissance plane as quickly as possible. However, a few hours later, the plane lost contact with the ground again.

Probably with the inexplicable disappearance of the first plane as a lesson from the past! The pilots of the second plane appeared to be quite cautious. He communicates with the ground tower almost every few minutes. Therefore, the ground command center has a clear idea of everything that happens on the route of the aircraft. And the last message sent back by this plane seems to say something. "What's that? Look...... It's like a giant fireball. It's flying off the ground, look. It seems like it's going to be me......"

The news was delivered to Tianxiang as quickly as possible. Look at this thin sheet of paper. He didn't say a word. It seems that he is lost in thought...... After a few minutes, as if he had suddenly come to his senses, he said eagerly to the guards beside him: "Order Fang Xu's troops to assemble immediately." Let the command center prepare a plane as quickly as possible, and I will rush to the northern capital immediately. At the same time, a supreme alert order was issued, so that all armies were ready for all battles. "The distance between the northern capital and Base 1 is not far. In addition, after the opening of the base, a new road connecting the two places was built. Therefore, at the speed of a small air-cushion vehicle, it only takes more than ten minutes to complete the one-way journey between Beidu Airport and the base. Therefore, when Tianxiang's figure appeared in the central control room of the No. 1 computer, the time was only more than two hours later.

"It seems that we are completely on the same page." The computer's unique electronic synthesis voice sounded in the empty room: "It's just that even I didn't expect that the plane crash would be related to this incident." It seems that we are still underestimating our opponents. "It's not difficult to shoot down a plane from an altitude of 20,000 meters. Of course. I mean the military power of the dragons. Judging by the last message sent back to the ground, it was supposed to be some kind of long-range anti-aircraft weapon that shot down the plane. If this is the case, then is the defense force on the northern border too thin? ”

"You're right." The computer sighed: "Although the fortress is strong, it can't keep all the enemies out. What's more, if the other side has the ability to blow up all these fortresses. This is definitely not good news for anyone. "In that case, will you help me?" Tianxiang's question was full of eagerness and anxiety.

“…… Help ......" The computer hesitated.

"What? Isn't it possible? "Probably can't help you more......"

"I know, your maker is Zhao Lun. But he's also an intelligent human! What's more, all the "pathfinders", including me, are also derived from his genes. Helping me is actually helping him!" You're wrong, my maker...... Actually, it's not him. ”

"This, how is this possible?" Tianxiang exclaimed in surprise: "Didn't you once say that he is the only master of all intelligent computers?" "That's exactly what I said." The computer's voice sounded a little helpless: "But...... But...... The master is not the maker. Although all intelligent computers are subject to his will, we are not the products of his creation. It's the same as the ancient slave society, where human beings were born from their mother's womb, but could only obey the wishes of their slave owners. ”

Although there are not many words, the truth in them is very clear.

"You mean, the makers of smart computers...... Someone else? "Yes." The computer replied affirmatively: "It's also a computer, but it's far more powerful than us, even incredibly powerful." Its name is "Zhilong".
