To put it simply, a 100-storey, 5,000-resident building only needs a 0.2 cubic meter ion battery to supply all residents of the building with electricity for 3 months!

-- This is a 10,000-fold compression-ion battery for civilian use, and it is said that the compression level for industrial and military applications is more than a few hundred thousand times or even a million times.

However, this is also the great progress of energy technology, and the others, at most, are technologies that have exceeded the hundreds of years of time on the earth on Zhou Sheng's side;

Who makes people have fewer families!

Even now in 2217, the world's population is only three billion!

Sufficient resources per capita!

The strength of the new energy source has completely reduced the traditional oil system and has disappeared from the earth for a hundred years;

The traditional way of power transmission has also completely declined, and there is no need to build resource-consuming transmission pipelines and lines, and only a suitcase-sized ion battery is needed, which replaces the original infrastructure that has been laboring for a long time and costing people and money;

Some scientists predict that in another 50 years, it will be able to enter the era of universal space migration.

However, at this time, an alien invasion species invaded the Earth.

A meteor shower that humans did not expect has hit the earth;

Originally, for the prediction of orbit, these space meteorites would not even pass through the solar system. As if they had detected the existence of the earth, they actually changed their flight path and came straight to the ground, and by the time humans found out, it was already too late.

In fact, these meteorites are the flying machines of those invasive species!

Just one day. These meteorites land evenly in every corner of the earth, and the shock wave that descends. Directly destroyed half of the human city.

And as soon as they reacted from the shockwave disaster, humanity realized it again. A second wave of alien invasions ensued.

It turns out that these meteorites that landed are actually alien biochemical giant trees:

They release invasive species and exterminate a qiē creature; Stretch the roots and branches and leaves to plunder all resources, water, air, and all kinds of materials in the soil;

Especially metal resources!

This is also the reason why Zhou Sheng did not see any metal supports in the wreckage of the building in the first place - they were all collected by the group of invading species that descended!

As for animals and plants, they released invasive species as soon as they landed, not only for humans, but also for all life on earth. The exterminating hunt is carried out, and the carcasses of organisms (including plants) are broken down into nutrients, and while they continue to grow themselves, new invasive species are cultivated indefinitely.

Of course, humans are not vegetarians either, and all kinds of mass killers that have been stored and maintained for many years have been reloaded into the gun chamber and launcher, which is not good for conventional strikes, and there are plasma bombs.

A plasma bomb is enough to completely destroy a qiē creature within a radius of 100 miles. The raging, high-temperature and high-velocity ionized plasma was enough to melt a single qiē within the reach of the bomb;

In terms of power alone, the power of this plasma bomb is far above that of a nuclear bomb; And there are no after-effects of nuclear bombs!

In the second wave of encounters. With the huge superiority of air strikes and the terrifying power of plasma bombs, humanity has almost wiped out 2/3 of the alien giant trees.

But. In this second confrontation in which humanity dominates, the human race has been building a city for an unknown number of years. and destroys five or six out of ten;

Before the invasion of invasive species, the census of the Earth in 2217 was three billion; After the second encounter. down to 1.7 billion;

The shock wave of the invasion species killed and buried nearly 700 million humans;

More than 300 million humans have been killed by invasive species;

……

On the fourth day of the arrival of the invasive species, humanity began its third confrontation with the invasive species:

Eventually, and before today, the third confrontation between humanity and the invasive species ended in a lose-lose situation for both sides;

Because, the invasive species base from the alien planet, which humans call the Biochemical Giant Tree, has hatched a flying invasive species!

Flying species, bird-shaped, two-winged, four-clawed, not large, all about three to five meters; But the terrifying thing is that it can move in the sky at a speed close to the speed of sound, and its claws and wings can directly tear through steel.

Humanity's air superiority has been shattered, and it can no longer unscrupulously pull bombs on alien invaders.

Long-range missiles will be destroyed by the flying species that are dispatched when they enter the detection range of the invading species; It doesn't work at all!

In this case, the unprepared human beings lost the first hand and were counterattacked, losing 1/3 of the city and population.

Many small countries have been completely erased from the map, and only a piece of wreckage remains!

Humanity is completely on the defensive!

Now, it is only seven days before the arrival of the invasive species;

Today is the afternoon of the eighth day of the arrival of the invasive species; On the afternoon of the first day of Zhou Sheng's arrival;

At this time, the remaining human population is about 1.3 billion, and there are still more than 30,000 giant trees in the alien base, and the invasive species are innumerable.

The two sides are licking their wounds and preparing for the next wave of exchanges.

"It's really fucking being forced to a life-and-death point!"

Looking at this information, Zhou Sheng couldn't help but burst into a foul mouth;

"In this case, the mission is to find out the source of this invasive species, and to protect a human base! This task is an easy one! ”

However, thinking about it like this, it is impossible for Zhou Sheng not to really do this task!

"Forget it, whether you can complete the task or not, you have to do it anyway;"

"Let's see where you are!" After clarifying his thoughts, Zhou Sheng began to prepare for the various matters of the mission;

Just like Google, there are similar websites on the Internet here, which provide map query functions, and this laptop can also be used as GPS, and Zhou Sheng finally found out where he is now - Huaxia, the suburbs of Qiyuan City;

Powerful network, even a detailed street map, the shops on the street, are displayed.

It's just that it's all ruins now! This powerful feature is useless anymore!

Continue to search for all kinds of materials on this network, and with the high-tech knowledge that he has previously analyzed, he has invaded the national network. access to information;

"Well, that's it!"

Zhou was born on the network of this earth. Plans for the standing armament in active service were found, as well as new ones. second-generation substitute for gunpowder): molecular formula G-1;

It has the characteristics of high explosive power and low sound;

Among firearms, the sound of ordinary submachine gun fire is only about 30 decibels, which is smaller than the sound of ordinary people when they speak;

On sniper rifles, the sound of shooting is about 45 decibels, which is the sound of ordinary people when they speak;

These things were found by Zhou Sheng in the most secondary research materials of the Academy of Sciences in Huaxia, and they are all common-sense things here, anyway, they are all high-tech things, if there is no corresponding equipment. It can't be synthesized at all;

And those special synthesizers are in the hands of the state;

The most important thing is that these things are in the hands of various countries;

Collecting these things, Zhou Sheng is preparing to use a small material reorganization instrument to assemble a single weapon on this earth;

Demon Hunter Remote Sniper, 12 mm caliber; The hunting range is 10,000 meters (within 10,000 meters, the power is enough to penetrate the special steel plate thick with a palm); The bullet has no deflection range (no gravity, wind force below level 6). 5 km; The weight is only 23 pounds;

However, because of the huge reaction force, it is also a special equipment in the army;

Daredevil glasses, a high-tech product with both telescopic and night vision functions;

Pull out the small material reorganization instrument that you have stuffed into the soul space. Zhou Sheng began to assemble these two things according to the information found in the national network;

There are also bullets equipped with demon hunter sniper rifles; and the clothes and shoes that Zhou Sheng prepared for the body he now occupies;

Fit for the action, snug up. Muffling;

After doing this, Zhou Sheng hid the assembled Demon Hunter sniper rifle and bullets. Put away the material reconstitution apparatus and bring the assembled clothes, shoes, and Daredevil glasses. reflexively went back to the ground, ready to bring the little white-collar girl up;

By the way, I collect some 'supplies' at the girl's 'next door'!

went down to the room where the little white-collar worker who was 'should' be called Meng Xian Xian, Zhou Sheng carefully knocked on the wall and went to 'next door' to shop!

The house next door is quite complete, with 3 rooms, 2 bedrooms and 1 bathroom;

The bedroom on one side is completely gone, only a door and wall remain, the bathroom in the middle and the bedroom on the right are preserved, and the room that Zhou Sheng knocked and came in is the living room of the family.

In the room, there are a lot of things, all kinds of things commonly used in life, it should be just that you are not at home when the disaster comes;

A few little pieces of cosmetics, cute little trinkets!

Here, it seems, should, probably, be a girl's room!

After looking at the room where he didn't know it was the girl, Zhou Sheng collected some useful things, some high-calorie food that he could carry, shoe polish, etc., and a pair of tall cloth boots!

And shoe polish and cloth shoes are prepared by Zhou Sheng for isolated white-collar workers!

Found a flashlight, Zhou Sheng pushed the switch and tried it, the light was on, and the brightness was very good, indicating that the power was sufficient.

But it's not useful to Zhou Sheng!

"Keep it for that hapless kid!"

Leaving the flashlight, Zhou Sheng continued to look through it to see what could be used;

At the very least, Zhou Sheng wants to disguise himself as a person in a disaster!

Entered the bathroom, turned on the faucet, unsurprisingly there was no water, only some echoes of the air, the waterproofing of the toilet tank was good, and there was a full tank of water, but it was useless, Zhou Sheng just wanted to disguise it, and he was not really forced to a dead end!

Putting the lid back, Zhou Sheng walked out, looked around, and looked at the layout of the room: in his current direction, the building on the right-hand side was basically damaged, and at the other end of the corridor, there was a corner on the left-hand side, which should be the kitchen.

Zhou Sheng walked over and found that he had guessed correctly, and there was a large dining table, which seemed to have the function of a dining room.

Although the power was cut off, the food in the refrigerator had not completely melted, and it seemed that the battle had taken place in the last two days, and the corpses outside had just begun to decompose;

I found some unopened drinks and bagged food, took out a few and looked at them, the production time was July 2217, and the origin was a green tea beverage group in a certain place; (To be continued......)
