The convoy entered the erosion zone, the scenery outside the window was desolate, and the car shook along the rugged road.

It's like a long-distance shuttle. Zhang Su thought to himself. But the end of this trip is hell.

The land is shattered and barren, and demons have polluted the wasteland.

Soldiers wear self-priming, filtering protective masks to avoid inhaling excess dust and ash in the air.

There was a mixture of mixed emotions in his eyes, and he couldn't tell whether it was hesitation or determination.

The chief officer sent by the defense force was an officer named Second Lieutenant Moriya, who had tanned skin and a meticulous expression.

"The planned construction target this time is located on the high ground codenamed 'Red Leaf Mountain', which is easy to defend and difficult to attack, and once we reach this place, we can defend against scattered demon forces." Moriya introduces the current situation in the mobile command vehicle.

After the rebellion of Kagura Mountain in the previous life, the human defense army overwhelmed the territory and swept the caves of the demon court, trying to offset the tragic retribution of the collapse of the wall of Dongzhou with meritorious deeds.

Zhang Su had participated in the counteroffensive, so he was very familiar with this area.

Momijiyama is indeed a good choice.

If they were able to safely pass through the 10-kilometer treacherous terrain, they would soon be able to establish a stable supply line between the mountain and the headquarters, opening up a safe passage for humans to enter the erosion zone.

A rugged mound appeared in Zhang Su's field of vision, which was the Red Leaf Mountain, which rose from the wasteland and could control a large area around it.

Once humans can build an outpost in Momiji Mountain, they can project many demons around the clear sky through firepower.

Demons love melee combat, and souls can only be sucked if they kill humans face to face, otherwise the human souls will escape.

Some demons are accustomed to shooting cold guns from a distance, but they can't eat their souls for a long time, and they become weakened.

"I'll plan the way forward." Zhang Su proposed.

Each order involved the life and death of 600 soldiers, and he doubted that no matter what he said, the line of fate on them would be reversed, which meant a heavy burden.

"You don't have more experience than our scouts." Second Lieutenant Moriya was skeptical.

"The demons are moving around all sorts of makeshift altars, and if we go forward like this, we'll soon run into one." Zhang Su said.

"We had a course of action before we set off, which was drawn up by Colonel Seibei." Second Lieutenant Moriya said.

Serious military men do not like to carry out unplanned orders. Everyone has their own style. Zhang Su was clear.

In less than half a minute, a telegram came from the car in front: "The enemy in front has found traces of demons, do you want to change the route?" ”

I've really met a demon!

Roaming imps and bladed demons wander aimlessly across the wilderness, convoys of oversized transport trucks that startle and deliver messages.

For their team, a single demon has the potential to reveal their whereabouts.

It is best for them to reach the Red Leaf Mountain in seclusion first, and then engage the demons, if they are delayed on the way, they will be discovered by the demon army in advance.

Second Lieutenant Moriya looked at Zhang Su with a slight surprise.

“…… From there, follow my route. Zhang Su mapped out a new path on the map.

"The route is full of sandstorms and dust storms, which are dangerous for the tires of the vehicles and the precision machines." Second Lieutenant Moriya pondered.

"The rewards outweigh the risks, so please stop now, change into dust covers, wrap the machine in plastic sheeting, tighten your military boots, and prepare to drive into the dust zone." Zhang Su ordered.

Second Lieutenant Moriya immediately made a decision and carried out Zhang Su's arrangement.

The convoy then paused to prepare for a dust storm through the erosion zone.

Although Zhang Su's path needed to pass through a heavy sandy area, it was better than being directly discovered by the demon.

The chaotic erosion zone is home to hidden demon altars, where demons etch elaborate ritual symbols into the ground, piecing together rituals out of obsidian, blood, or the limbs of their companions, communicating with the powerful demons they worship in the hope of gaining some favor.

The convoy set off again, bypassing the altar hidden in the hills and driving through the storm zone.

The wind was blowing, the sand and gravel were hitting the windows over and over again, like thousands of ghost hands, and some soldiers were suspicious, aiming their guns at the outer edge.

After passing through the heavy sand and dust, the investigation army outside the wall arrived at Red Leaf Mountain.

The others had a slight complaint about Zhang Su's arrangement, but they kept their mouths shut after finding that the convoy had arrived at Hongye Mountain unscathed.

"It's really time to Momijiyama......"

"Great, I didn't meet the demons......"

"The first step of the plan has been realized." They were satisfied, and many breathed a sigh of relief.

It is true that I avoided the colony of demons and only encountered a few demons. They scattered and fled, not daring to confront the hundreds of men and heavy vehicles.

They will send messages, but by then, the humans have established a stronghold in Red Leaf Mountain, and the "Sky Spear" cannon designed by Transwarp Technology will unleash its fire on the demons.

They climbed the 3.9-square-kilometre hill along the slope, the loose gravel on the slope creaking under the heavy tyres, and looked around to see the wide open view, which was easy to defend and difficult to attack.

Once at the top of the hill, they unloaded their building materials and began construction of the vital outpost, where soldiers quickly disembarked with boots and the sound of footsteps, sentries and orders.

Because Zhang Su showed foresight about the erosion zone, Second Lieutenant Moriya also respected his opinion more and referred to Zhang Su's professional ideas.

Now they were 10 kilometers away from the wall of Dongzhou, like the first nail that had been driven into the heart of a demon.

"Let's get to work." Second Lieutenant Moriya jumped out of the car, "Time is limited. Don't repeat the mistakes of the previous three surveys. ”

The team members were engaged in intense work.

The erosion zone is illuminated by the eternal blood-red sun, and there is no day or night. Demons can't be unaware and are planning a massive attack, so they must race against time.

Zhang Su inspects the cliffs of Momiji Mountain.

According to the results of the investigation, this is the best place to set up an outpost, not only because of the difficult terrain, but also because there are 4,500 tons of water stored inside, which can be mined by installing water purification equipment.

Soldiers unloaded supplies, including supplies, tools, materials, rations, and prefabricated shelter pods, from trucks, armoured vehicles, and the large shuttle.

Second Lieutenant Moriya personally commanded a unit of engineering robots to clear rubble and level the ground.

In addition to the small robot, there is also a large robot codenamed "Shenwu" put into work, designed by Yuwang Manufacturing Company designated by the Human Defense Program, 6 meters tall and weighing 100 tons, and the fleet has a heavy truck dedicated to transporting it.

It resembles a multi-armed King Kong, with four heavy-duty robotic arms quickly assembling prefabricated parts to form buildings and military fortifications.

Each robotic arm is equipped with a deformation drill bit, a welder unit, and a smart polymer nozzle at the end for instant material handling.

Like a very large mason, he quickly builds the defenses of Momijiyama to fend off the demon army that arrives at any time.

Zhang Su rolled up his sleeves and personally joined in the hard work, using his broad and muscular shoulders to carry the goods himself.

"Stronger than a robot...... If I had come, I would have been squashed a long time ago! ”

"No wonder he can be the one who oversees witches." The soldiers watched as Zhang Su loaded and unloaded hundreds of pounds of building materials from the car.

Steel was as light as plastic on his shoulders, and he walked in stride, making it easier to do a lot of work.

Wholehearted work, construction and labor.

The soldiers would rather defend the wall of Dongzhou than go on an expedition, so they have a lot of criticism about Zhang Su, who led the investigation outside the wall. But now, it seems that his determination to seal the gates of hell is serious.

Zhang Su lucked, and the sweat evaporated quickly.

He looked at the mountain, and the rust-colored cliffs seemed to be a world away, casting huge shadows on the ground, which seemed strange to him.

What did this land look like before it was assimilated by Hell? In their previous lives, they didn't seal the gates of hell, so they had no way of knowing.

Today there is no trace of life here, only lifeless rocks and sand.

The sky was filled with smoke, and the scarlet blood sun hung low.

It's covered in knife marks, all of which were cut out by Saho's mother, the Shadow Witch.

In order to find a secluded place to cultivate, she slashed many demons, expanded and broke into the gates of hell, and went to the Infernal Hell, leaving a witch egg in the human world, and also leaving behind the mess of Kagura Mountain, so that the demons roamed rampant, and the erosion zone expanded day by day.

How can you resist the next demonic attack and reclaim this land? Competent decision-makers must always ask themselves questions.

Zhang Su initiated the fourth extramural investigation, and he is constantly evaluating the feasibility of the plan.

He believed that there was hope for the gates of hell to be restored.

"Zipline." Roy stood in place and launched a zipline towards the end of the far camp so they could lift the cargo far away.

After the construction of the basic barracks, the "Shenwu" engineering robot continued to unfold, and after building the basic barracks, it took heavy steps, cutting the surface and digging the foundation with a huge laser beam, preparing for the subsequent construction of high-speed projects.

Primeur, the Casting Witch, began her work, fully embodying the Casting Witch's hands like an advanced workbench, her magic radiating into an ever-expanding lattice matrix.

In her hands, the chips from Transwarp were synthesized into a more complex beacon grid to connect with the signal bands of the Defense Forces.

As long as Priscilla sets up a well-functioning communication facility, the invincible air force of mankind will be able to enter the airspace in time to bombard the demons indiscriminately and ensure the safety of Momiji Mountain.

Akasawa smelled the smell of war, and immediately set up a marching pot before fighting the demons.

She piles up the stones everywhere into a ring with a dozen solid fuels in it, lights it with a lighter, blows air into it, and makes a fire.

Yoshiyo Akasawa takes out his favorite food from the logistical supplies and prepares to put his cooking skills to the next level, making a family-heirloom stew.

As the hot fuel boiled, she hung an iron pot over the fire and added carefully sliced oregano, lotus roots, carrots and bamboo shoots, as well as chunks of pastrami and dried shiitake mushrooms.

Shiitake mushrooms quickly swell in the hot soup and give off a rich aroma, followed by a can of beer.

She stirs the pot with a long wooden spoon to gauge the temperature by looking at the foam and bubbles, and soon she adds potato wedges, cabbage, tofu, ginger, cod and kelp seaweed, and finally chopped green onions and minced garlic.

She filled herself with a bowl of food, which was super delicious, hot food rolling on her tongue, plenty of nutrients hitting her gut and making her magic and physical strength rise quickly.

After each meal, her combat power increases dramatically.

Spirits, stew, and sleep are the three treasures that Yoshiyo Akasawa uses to deliver the perfect blow, helping her defeat demons.

Yoshiyo Akasawa cherishes the taste of the food, because she doesn't know if this will be the last meal.

Within an hour, many prefabricated barracks were built.

Turrets and automatic machine guns are deployed, and the Shenwu Engineering Robot places its heavy anti-aircraft guns in a well-grounded location with a good view to fend off demons from the sky.

Smaller drones dig bomb shelters, underground tunnels, and warehouses underground.

Temporary berths for vehicles, warehouses, barracks, outlying positions, artillery positions, headquarters and communications centers, underground facilities, field hospitals......

Countless facilities have risen in front of Zhang Su! Both the scale and the quality are considerable.

The human defense plan is at its most efficient here, they are used to such efforts, everything is to build up their combat power as quickly as possible to resist the demons.
