Legend of Tiger Wolf

The fire on the ground gradually extinguished after half a year, and the entire earth's atmosphere was shrouded in thick volcanic ash, preventing sunlight from shining in, causing the surface temperature to continue to drop.

The Arctic and Antarctic ice caps and glaciers in various places melted by the fire caused the sea level to rise sharply, and large floods gushed out from the mountains, submerging large areas of land.After the flames all over the world were extinguished, gray-black snowflakes floated down from the sky, and one after another fell on the ground and water, first turning into water, and then no longer melting.All the rivers, lakes and seas on the ground have started to freeze, but very few of them are white, and there are dark gray, pitch black, earthy yellow and other strange colors everywhere, and some seem to have terrible foamy substances on the surface, revealing dilapidation and destruction breath.

There are no more cameras left on the ground. Only some pinhole cameras embedded in high mountains with special technology and a very small number of detection devices are still working and can observe limited areas.These images and data will not be made public, and only relevant research institutions and senior leaders of the central government can see them.

The first year of the dungeon was spent in a peaceful and peaceful atmosphere. Partial construction has been going on, but no information has been disclosed. Most people have gradually settled down. The safe and comfortable living environment here makes them feel at ease .

Ling Zihan's condition still hasn't improved significantly, but it hasn't deteriorated further either.Wei Tianyu is very patient, as long as his condition can be maintained, that is a good thing.

The days passed quickly, Wei Tianyu and Fang Cheng started their research on a new topic, and the Xiaoyao brothers also participated in their spare time.

After the completion of the Lingkong School located in the Lingkong area on the second floor of the underground city, the children all went to boarding, and the core area became quieter.Ling Zihan adjusted his mood and lived a leisurely life. When he was awake, he would sit up and read books, listen to music, watch news and movies.

Apocalyptic novels and movies are still popular, and the imagination is more abundant. The two major series of Resident Evil and Alien have been filmed dozens of times, and they are still enduring. All kinds of movies and TV shows of aliens invading the earth flooded every channel, and the computer special effects were all done beautifully.

The current news channels do not have so many valuable news to report, so most of the time they show science and education films, special interviews and expert lectures. Ling Zihan occasionally watches them, but most of the programs for the public only talk about the surface and do not go deep. The central idea is to report the good news but not the bad news, so as to appease the public's emotions, so he rarely spends time watching the show from the beginning to the end, and often changes programs after just listening for a few minutes.

The star grass in the courtyard grows taller slowly, and every sky-blue blade of grass emits a little silver light, like a sky full of stars, which is extraordinarily beautiful in the special environment of the dungeon, which makes people feel at ease when they see it Give birth to a sense of peace and tranquility, and then the tense mood will gradually relax.This is a perennial herbaceous plant, which is not tolerant to cold and intense heat. It is easy to grow under a constant temperature, water it, and apply organic flower fertilizer every three months, and it will be full of vitality.

Now the landscaping department has planted this kind of grass all over the city, together with various flowers and trees, to decorate the underground city beautifully.Almost everyone thinks that life will be peaceful and peaceful, and everyone can return to the surface after hiding underground for decades and recreate a better world, but Ling Zihan can intuitively feel that the crisis is getting closer and closer, and it is almost imminent.

After thinking for several days, he managed to sort out a clue from his chaotic mind, so he asked Wei Tianyu, "Do all our dungeons have lock procedures?"

The so-called "lockdown procedure" is to completely close the access to the ground.In order for the army or national security personnel to attack quickly, each dungeon has reserved exits leading to the ground, and the "locking procedure" is to set the opening level of these exits to the highest level, and theoretically there will be no Any hacker can intrude and modify.

When Ling Zihan asked this sentence, it meant that the authority to open the exits of the top ten cities would be withdrawn, and no one would be forcibly allowed to open the exits.

Wei Tianyu called up the defense systems of the top ten cities from the database to check one by one, and then said: "It is not locked. The military and political leaders of each city have the authority to open the exit when necessary."

"Hmm." Ling Zihan pondered for a moment, "Could you set up a lockout procedure in an emergency on top of this authority? In the event of an accident, you can manipulate the defense systems of ten cities to lock down automatically and refuse to execute other people's orders." instruction."

"Are you sure?" Wei Tianyu was a little surprised, "Isn't this matter approved by other leaders of the National Security Council?"

"Adding a small program is nothing more than adding another insurance. This is just a technical problem, and there is no need to make a big fuss." Ling Zihan said calmly, "To start this program, you need to notify them."

"Well, that's right." Wei Tianyu nodded immediately, "Then I'll do it right away."

Ling Zihan stretched his waist and asked with a smile, "Is the subway open to traffic?"

"Not yet." Wei Tianyu opened a map of the intercity transportation network and zoomed in for him to see, "It is relatively far from our Jiugong City to several other cities, and it is only half completed now, and it may take another year to open to traffic. "

"Oh." Ling Zihan looked at the big screen on the wall and thought about it for a while, then took a deep breath and relaxed, "Then if you install a lock program on those cities through the Internet, won't people find out? Also, How do you control those programs if the cables to the various dungeons are down and you can't connect to the internet?"

Wei Tianyu said with a smile: "I think it is possible to install a pre-program for automatic identification and set a few key items. As long as these conditions are met, the master control computer of the dungeon will automatically open the lock program. If it is finally determined that it is a misjudgment , I can unlock it later, do you think it will work?"

Ling Zihan closed his eyes slightly, as if he had fallen into a deep sleep.Wei Tianyu understood that he was sensing something in the dark, so he sat beside him silently and waited.After a while, Ling Zihan opened his eyes, with a serious expression on his brows, "I can't describe the feeling, but I feel that there are loopholes in the plan you proposed, which is not safe. I mean you are now Directly lock all exits in every city, and no one is allowed to go to the ground."

Wei Tianyu's expression also changed, "Is it so serious?" Ling Zihan nodded slowly, "Yes."

"That's good." Wei Tianyu didn't ask any more, "I'll deal with this matter immediately and lock all the dungeons as quickly as possible."

Ling Zihan emphasized, "We can't control other people's cities, but our own underground city and the two cities in South Asia that we helped build must be locked. In extraordinary times, compulsory measures must be taken."

"Okay." Wei Tianyu agreed without hesitation, "I'll transfer a few people and form a special team to do it."

Looking at his back as he left in a hurry, Ling Zihan sighed.Sitting there in silence for a long time, he slowly stood up and decided to visit his little son who was learning to walk, and let the child's innocent and cheerful smile dilute the inexplicable worries in his heart.
