After the powder, a large black 'hole' was revealed, and a long staircase led to the ground.

"It's finished?" Liu Ye and Nan Tiancheng were a little in a daze.

"It seems that the fortifications of this square building are a bit like tempered glass, either nothing at all, or all of them are shattered!" Seeing the scene in front of him, Liu Ye somewhat understood.

"Lie' Attention!" The jade ''gate' has been opened, and the second plan begins, and the squads are ready to assault and occupy the ruins. Liu Ye ordered directly.

"In addition, the construction personnel collected the powder around the square building and brought it back to the construction department for research!" Liu Ye did not forget the construction that made him spend a lot of time just now, and ordered his subordinates.

This is the control base of the 'jade' belt system.

The 'Jade' Belt is a global defense system signed by mankind before the war, and this global defense system was originally intended to defend against stars in outer space, prevent them from hitting the earth, and destroy them in advance once discovered.

However, when the 'jade' belt system was built, the design was changed. Environmental scientists have called for the construction of a giant controllable sun umbrella on the 'jade' belt system to block the sun and prevent ultraviolet rays from continuing to harm the earth's life.

Due to the development of human science and technology, the earth's environment is seriously polluted, the ozone layer has been thinned repeatedly, there have been different degrees of ozone hollows in the North and South Poles, and the global temperature has also warmed repeatedly.

In order to stop the further deterioration of the global environment, humans have come up with the idea of erecting parasols on the 'jade' belt tracks, which are made of treated metal sheets to form a ring.

This ring-shaped parasol blocks sunlight and 'shoots' it back, thereby lowering the Earth's temperature and curbing global warming.

The ring parasol can also act as a solar energy absorber, greatly improving the energy efficiency of the 'jade' belt system.

It was assumed that a motion was passed at the federation, and this proposal only added a setting to the 'jade' belt system and did not interfere with the original design.

According to scientists' predictions, the Earth's ozone layer can recover again after only three years of blocking sunlight, and the Earth's environment will regress to the pleasant environment of 200 years ago.

According to the records of the mastermind, the earth's temperature did drop within a year of initial use, but then a series of environmental problems appeared, which made people anxious.

Due to the lack of light, the output of grain crops in various places has repeatedly declined, and fruits and vegetables in many places have also appeared to varying degrees of disease.

Almost all industries that need solar energy have been hit, so the governments of various countries have asked the United Nations to urgently turn off the shading function of the 'jade' belt and restore sunlight.

This proposal was of course rejected by scientists, who believed that such problems were normal, but now turning off the shading function would nullify all previous efforts.

As a result, there has been a protracted war of words and foreign 'diplomacy' in the international community, and people have launched a 'fierce' debate on this issue.

Later, in the face of strong demands from various countries, scientists had to give in and agree to turn off the shading function for a period of time every year to allow sunlight to re-enter the earth.

Originally, this matter was over, and the politicians of those countries also understood that going on like this would not be beneficial to their long-term development.

But just at the end of the matter, war broke out.

The reduction in sunshine has made the world's already strained energy sources even more urgent, and OPEC has once again announced a reduction in oil supplies for its own benefit.

This announcement became the straw that broke the camel's back, and the NATO-led military organizations launched the 10th Gulf War for the sake of energy and resources.

The flames of the Gulf War spread rapidly, from the NATO military organization to the Warsaw military organization and the Chinese alliance, and finally to the whole world, forming the third world war.

At the end of the war, NATO, which was in decline, launched a nuclear bomb in a frenzy, and the Japanese betrayed it at that time. The Huaxia Alliance was caught off guard, and the capital was hit and turned into a scorched earth.

At that time, the control center of the 'jade' belt system also happened to be destroyed, and in order to retaliate against NATO and Russia, the Chinese alliance also 'fired' nuclear bombs. All countries in the world have been 'affected', and mankind has collapsed and perished.

The Jade Belt, which was supposed to be closed after three years, was forgotten, and the Earth fell into a long period of darkness.

This matter was told to Liu Ye by the mastermind a month ago, telling him that the solar day was coming, and this was the best time to turn off the 'jade' belt system.

This is exactly the purpose of Liu Ye's visit, according to the procedure set a hundred years ago, to close the "'jade' belt" forever.

"Access to the stairs...... The third junction...... Turn right...... Signage...... That's right, this is it! "Liu Ye and Nan Tiancheng first rushed into the black 'hole' that was 'exposed' out of the square building, ran through the empty hall, and came to a large metal 'door' with a blue 'color' sign after a dash.

According to what the master said, this 'door' is the guard 'gate' that must be entered to enter the control center of the 'jade' belt, and as long as you pass through here, you can reach the control center.

"There is no mechanism!"

"Can't find the opener!"

"No hints!"

A team of city-dwellers stepped forward to inspect it for a week and said.

"Again! But luckily I'm prepared! Stand back for me! Hearing the city's answer, Liu Ye 'revealed' a smug smile on his face. At this moment, the dragon scale formation on his body had not faded, and he saw that he opened the scale armor on his left shoulder and turned out a small 'shooting' device.

"Huh~la~snort~la~!"

The sound of energy gathering came, and soon a ball of light surrounded by white 'color' electricity appeared at the muzzle of the 'shooting' device, and the ball of light continued to expand, and finally burst out, making close contact with the alloy 'door' in front of it.

呲~~

There was no rumbling sound, only the scalp-numbing sound of melting metal, and the alloy 'door' in front of him looked like a scorched candle, and under the attack of the particle cannon, a semicircular breach more than a person high was 'revealed'.

Liu Ye didn't stop, he squinted his eyes slightly and rushed in, and the others followed closely behind Liu Ye.

Behind the alloy 'door' is a small space, rows of flashing red and green lights on the roof, and blue 'color' arcs emitted by computers still working, all indicating that this control center is still faithfully carrying out the work of a hundred years ago.

Liu Ye and the others were extremely excited in their hearts, and they finally arrived at their destination after spending so much effort.

It's just that they didn't pay attention, a gun hole stretched out from the 'yin' dark corner of the rear, aiming at Liu Ye and his party.

A pale red 'color' light emitted, and a citizen standing at the back of the city was horrified to find that his lower body and upper body had been separated at some point, and only then did he feel a sharp pain.

"It's a mechanical guard! Everyone disperses, looking for cover, hurry! Liu Ye was the first to find out about the death of the city's citizens, and he didn't have time to explain anything, so he roared loudly.

At the same time, Liu Ye suddenly jumped up and rushed towards the mechanical guard.

The barrel of the mechanical guard immediately locked on to Liu Ye, and as his body kept moving around, from time to time the metal pipe wall was 'shot' by the mechanical guard and fell down. The tinkling sound is non-stop, which makes the already messy scene even more 'chaotic' and 'chaotic'.

Da-da-da-da!

The person was still in the air, so Liu Ye took the AK-99 in his hand and shot fiercely at the mechanical guard, but it was useless, except for a few more bullet marks on the guard's mechanical body.

"Nan Tiancheng, the commander will give it a blow with rocket artillery! Others attack with grenades, don't worry about me! Concentrate your fire to take it out! "Liu Ye, who was jumping like a monkey, hurriedly yelled, he didn't dare to stop now, Menglong had warned him more than once that he was locked by mechanical guards.

If it was just Liu Ye alone, he could definitely kill him with his own strength, but there were other city residents around. Just now because of his negligence, one had already died, and Liu Ye didn't want to let his citymen take any more risks.

Sou! The rocket launchers on Nantiancheng's side were finally installed and fired, followed by six electromagnetic grenades that came in a parabola.

After a thud, the scattered corpses dispersed with disgust, and the heavy body of the mechanical guard could no longer bear it, and fell off the staircase, causing a 'stirring' sound of metal colliding with the ground.

"Well done! Clever! Liu Ye praised and rushed to the side of the mechanical guard, raising the AK-99 to the crack on the surface of the mechanical guard.

The sound of crackling arcs was remembered, and the red 'color' light in the mechanical guard's eyes dimmed, and gradually fell silent.

"Shi Qiang, clean up this brother's corpse and take your people to guard the stairs!"

"Nan Tiancheng, bring the computer programmer, follow me!" Liu Ye came over with a body full of dust, and he was startled by the accident just now, but fortunately, the loss was not big.

The computer programmer pressed the keyboard, turned his head and asked, "Turn off all the alert systems?" “

"No, you don't! As long as the alert system to the control center is turned off! Liu Ye threw the depleted AK-99 into Nan Tiancheng's hand, and said in a deep voice: "Other alert systems, maybe they can be used in the future!" Now the marker line comes, we have to move fast, who knows what else awaits us! ”

"Yes!" The computer programmer responded, his hands flying up and down on the keyboard, and soon a three-dimensional architectural department outlined with lines appeared in front of the computer screen, and one of the lines marked by green 'color' photoelectricity was the route behind Liu Ye and them.

"Still going to the ground? Twenty-three floors? That's a good number! Liu Ye stared at the screen, and after confirming that it was correct, he walked out of the control room and shouted to everyone:

"The second squad is on guard here! The 1st and 3rd squads come with me! ”
