The Hell Plane is a huge world on a near-cosmic scale, and it is impossible to solve the problem of demons at the root.

Demons will kill and devour souls, and just as hell will devour the souls of ordinary people in all worlds to strengthen themselves.

At the operational meeting, there was a round of debate among the generals about how to fight, and some said that they would intervene with manpower and use various weapons of mass destruction in the hell position.

But human life is very valuable, so many lands on the earth need people to protect every place, and there is simply not so much combat power that can be consumed in hell.

Then some people said that unmanned equipment is used, although this proposal is very good, but the manufacture of unmanned equipment also costs money, hell is so big, no matter how many unmanned equipment they build, they can't fill it!

Doesn't it matter?

That's not it, the problem is not how to deal with hell, but how to deal with it in order to get benefits, at least not in a state of making ends meet, otherwise how to maintain the high welfare of society, and how to maintain the rapid development of plane joint organizations and groups?

As mentioned earlier, the Demon Generator can be tried, and the stones that are special to Hell may be able to find a way to use them, and I don't know if there are any special ores in Hell either.

It would be easier to deal with the unmanned equipment if it could expand itself in the Underworld, and the Furnace of Hope, which is currently capable of converting stone into metal, has undergone two rounds of upgrades and is now capable of producing at least a few more elements.

The periodic table has been partially conquered and can be applied in unmanned chemical plants.

It is still complicated to realize the self-operation and self-repair functions of the equipment, but fortunately, the group's current technology can do this.

After a month of careful study and discussion, the military department decided to unite scientists interested in hell to conduct a detailed investigation of the hell plane.

And let the laboratories that have obtained samples of various things in hell transform materials into valuable commodities, which can lose some money, but are afraid of sticking too much money.

First of all, the stones in the hell plane are also stones, but they can be classified as new types of stones, which have good earthquake resistance and high temperature resistance, and can be collected and sold as slates, but the color is not very easy to wash, and it is brownish-yellow.

Secondly, it is the ore in hell, the ore element in hell is basically the same as the universe in the ordinary world, but with a small amount of sub-gold energy characteristics, this kind of sub-gold energy that can be shaped into various forms is stored in large quantities in the metals of hell, and the ores in hell can be processed into good metal raw materials.

These materials have a good conduction effect on metal materials and sub-gold energy, and their strength is stronger than that of ordinary metals, so they can be used as special materials.

A demon generator that eats garbage has also been made, using biogas combustion to drive turbines to generate electricity, a demon generator is five meters high, four meters wide, and six meters long, which can process 20 tons of garbage a day and produce 12,000 kilowatt-hours of electricity.

They will build power plants on the in-situ plane of hell, process megatons of garbage every day, and send the electricity produced to other worlds through battery packs.

Not only the Gluttonous Demon Generator, but the Little Devil can also be used as a generator, and the Manic Little Devil will often throw fireballs, and the temperature of the fireball explosion is not low, so it can also be used.

The same is true of the beams on the Hellbreaker's right hand, the energy they shoot is manifested in the most intuitive form of heat, which can be collected and utilized.

Even though the group now has a variety of energy production technologies, all of them are more expensive than Hell Biopower, and the cost of building a set of antimatter power generation equipment is enough to build sixty Gluttonous Demon Waste Recycling Plants.

The feedback from various research results strengthened the group's determination, and finally after designing all the equipment drawings necessary for the construction of the factory, the hell development plan began!

The 6.3 million Navy and Army and the 720,000 engineering team used the Mars of the strange world as a springboard to march into Hell on a large scale, and came to the Shadow Plains where Ultron had arrived!

Countless warships and mechs filled every corner of the plain, and a large number of demons who were fighting each other on the vast plain were grabbed by the army that suddenly appeared in the next moment.

Those who resist and disobey all have their limbs cut off, and if they are high-value units, such as the Gluttonous Demon and the Helldestroyer, they will be controlled and temporarily imprisoned with restraints.

An army of 6 million seized a corner of the Shadow Plains, and the 720,000-strong engineering team quickly entered the field with building materials and engineering equipment, and built huge factories directly out of steel on the Shadow Plains.

Modular construction did not take time, the engineering team only had to dig hundreds of deep enough holes in the plain ground, and then insert steel bars into them to fix them, and the bare surface part became the framework of the factory.

Steel plates are inserted between the reinforcing bars as the exterior wall, and the ceiling is spliced with curved panels, which are supported by the forces of interaction.

Seventy-two factories were set up quickly, sprayed with a special coating to cover the dust, and the equipment was transported into the factory in batches through dimensional lasso to complete the assembly.

Because the little devil is the most demon in hell, fifty of these power plants are small devil power plants that use the little devil to throw fireballs to generate electricity.

Of the twenty-two factories, fifteen are garbage disposal plants, five are hell destroyer power plants, and the remaining two are meat processing plants, processing demonic meat.

It took less than half a day to install the plant and equipment, and those restless demons that couldn't be caught were put to use.

Front-trained staff enter the factory in white engineering exoskeleton armor and let the soldiers bring different demons into the factory.

The screaming and struggling imp was impotent and furious under the strong body of the army soldier, and finally pressed against the pre-treated metal table, his legs were cut off by the machine, and the bleeding was stopped by the heat and put on the conveyor belt.

The little devils who lost their legs were held together by their palms to stop them from unleashing fireballs to destroy the machine before they reached their intended position.

The conveyor belt sent the little devil to the next processing point, and the waiting staff there used pliers to expand the little devil's mouth, then used a hammer to crack the sharp teeth, and then applied a special gel around the teeth to seal the possibility of it continuing to grow teeth.

The imp, who had been tormented for two rounds, was thrown into the conveyor belt again, and was shackled by the last staff member to a long cabinet just enough to fit the imp into, its palms released and aimed at the energy harvester, and its mouth tucked into a food delivery tube.

The severed legs and teeth are then transferred to a meat processing plant, where they are mashed into a mash and fed again.

The enraged imp begins to condense a fireball, which explodes on the target, and the heat generated by the explosion is recovered and used as heat to generate electricity.

It is hoped that the furnace will convert the ubiquitous stones into water, and let the collected heat heat heat the water in the steam turbine, and finally generate electricity by pushing the turbine.

Working in three threads, the first little devil power plant was soon crammed into more than a thousand little devils, and the generators also turned, and the power was continuously poured into the blue energy block.

The employees of Hell Destroyer's power plant are similar to the way the little devils are hired.

With the exception of the power-emitting right hand, the Helldestroyer's limbs were chopped off, his teeth shattered and placed in a cupboard, and his mouth was also plugged with an esophagus.

Unlike the Imps, the Hellbuster has a high power generation efficiency.

The energy beams they emit can reach temperatures of up to 6,000 degrees Celsius, and the heat collected is enough to boil more water and propel larger turbines to turn.

Two factories are up and running, and a third plant has new employees.

The mecha takes the Gluttony Demon into the depths of the garbage disposal plant, and the Gluttony Demon is an explosive demon that inserts a tube into the Gluttonous Demon's round belly to release the swamp gas before cutting off their limbs.

Make sure they don't explode and then cut off their legs, cover the wounds with discs and nail them.

After that, the mouth will be brutally surgically reconstructed, and then the tongue will be cut out before it can be put into the black box to be used as a generator.

Once in the black box, the gluttonous demon will not stop generating electricity until it dies, and the tens of trillions and hundreds of millions of tons of garbage produced by humans every day need to be disposed of by this environmentally friendly machine.

The garbage sloped down from the feed opening, and the surgically modified mouth was stuffed with serrations, and as the garbage sloped down, the machine was running, and a large amount of garbage was crushed, directly into the stomach pouch of the gluttonous demon.

Two-thirds of the Gluttony's fat and bloated body is a stomach, so the Gluttony Demon only has an effect comparable to a missile bombardment when it explodes.

"Gross! Vomit! ”

The gluttonous demon in the machine kept making strange noises, and the engineer outside the machine saw that the machine was running normally, and the biogas began to burn to push the turbine to generate electricity, and then nodded with satisfaction, and casually closed the side panels, and the screws were directly screwed to death.

……

The army of six million, except for the 500,000 people and supplies left behind, all expanded outward with supply ships as the core to capture the demons scurrying in the plains.

Lesser Devils, Hell Destroyers, and Gluttonous Demons are all of high value and can be captured alive.

The remaining Hell Knights, Pink Devils, and others who have no economic value for the time being will be killed, and the corpses will be processed into demon feed at the meat processing factory.

Take this, use this.

Half a million troops still have to go to prospecting, and there are also many exposed mineral deposits in the vast Shadow Plains, and after finding rich ore, they will unload automatic mining platforms and self-exploding drone factories from supply ships to carry out unmanned operations.

The rumbling giant machine roared, the metal bucket fell again and again, digging the earth, and a series of cleansing in the principality eventually turned into slag, which was cauterized and placed into the storage room, and when the storage room was full, the machine would activate the dimensional lasso and send the produced hell metal ingots to the factory's warehouse.

Cold, efficient.

The drone factory acts as an umbrella for the autonomous mining platform, and when it detects that the demon is close to a range of five kilometers, it will release the drone to kill the demon.

Mobile factories descend from the sky, and the roar of steel behemoths shatters the silence of hell.

Soon the demon spotted this group of uninvited guests, and let out a screaming laugh, only the demon has invaded other worlds, and it is the first time that it has been invaded!

】

The demon lords with advanced wisdom were all laughed out loud in anger, and immediately began to gather the demon army to crusade against the invaders.

The demons gathered in large numbers were soon discovered by the group's army, and the pace of expansion was temporarily slowed.

Soon, several demonic armies were killed, and a large number of ground and air units were approaching like a line connecting heaven and earth.

The group's warships were aimed in the direction of the demon army with their flanks, and the ground forces also formed an impregnable defense line with tanks as the core phalanx.

As the demon army approached 10 km, all the ships fired shells together.

The electromagnetically propelled projectile exploded in mid-air after reaching the predetermined position, and white spider silk flew out all over the sky, netting the demons in the sky, and after falling, netting the demons on the ground.

Thousands of spider silk shells were fired one after another, and the range was extremely wide, and the amount of spider silk blasted by the spider silk shells was also very large.

Peter Parker has a small bottle the size of his index finger tied to his wrist, which can swing around the city for hours, and the cannonball is loaded with two kilograms, and after exploding, the spider silk shoots directly out for nearly 100 meters, becoming a real spider web.

The dense cannonballs netted one demon after another, and the charging demon could not get out of the spider silk and would also fall.

The posture of the demon army's charge was intercepted in the continuous spider silk shells, and the army on the ground looked at the demons that were still numerous, and felt that they couldn't catch it, so they let the tank array open fire and knock out some of them.

Boom Boom!

A large number of shells fired by the electromagnetic tank fell into the encirclement web of the spider silk, and the demons that could not be dodged were blown apart by the explosion, and the scattered shrapnel killed countless demons.

There were still plenty of demons in waves, and finally the hive battleship dispatched a swarm of drones to clear a large area of demons with sheer numbers and firepower.

Compared with the war race, man-made weapons of war still triumph in productivity.

Demons will flee when they sense that something is wrong, they are not ignorant of fear, and there are many beings in hell that can make demons fearful, such as high-level demons, and the green man......

The fleeing demon was intercepted by the spider silk again, and the infantry in the rear began to press, and the physique of the captain per capita was not much worse than that of the demon, especially with equipment bonuses.

A large number of demons that have not yet died are transported back to the factory, and the tenacious demons can be alive again as long as they are fed a little feed, and it is better to blow up their legs, and it also saves a process of joining the factory.

The first factory to be filled was the Little Devil Power Plant, which covers an area of 1.2 square kilometers and can accommodate nearly 100,000 Little Devils, with an average working area of 35 square centimeters, and 5.5 Little Devils are stuffed into a small space of one square meter.

It is estimated that the daily output of electricity is 29 million kilowatt-hours, which is much more than that of a thermal power station of the same size, and the cost is very low, green and pollution-free.

A large number of little devils have made a lot of contributions to the green cause, and the second power station is quickly filled.

The Helldestroyer power plant was slower, with the first plant crammed into 3,000 employees.

The Gluttonous Demon Waste Treatment Plant is even smaller, with only 200 employees, and their daily job is to binge-eat the food produced by the six million army to give back to the company's cultivation.
