Zhang Su drove, silently looking at the out-of-phase space at the top of Kagura Mountain.

A sea of lava flowed on the top of the mountain, and the remnant sun shone scarlet fire.

The world was in danger for Zhang Su, the world line was deflected many times, and in 1861, the American Civil War attracted the opening of a door to hell.

The blood shed by humans attracts demons, who smell death from the high-dimensional hell and take a desperate turn.

The soldiers of the two armies were still fighting for Maryland, bayonets glistening in the summer sun and artillery roaring.

Suddenly a hole opened in the sky, and the whirlpool opened like a giant mouth full of sharp teeth.

Within minutes, 200,000 soul-hungry demons leaped from it, their piercing screams flooding the battlefield more piercing than any cannonball, their strong bodies crushing human bones, bloodthirsty claws chasing deserters.

At least one-third of the demons fell to their deaths on the spot, but the others became stronger by devouring the souls of their dead companions.

The demon killed all the northern and southern armies in this way, and the soul was enough to feed hundreds of imps into big demons. Tasting such sweetness, the gates of hell are more and more.

North America was defeated, slavery was never abolished, Washington survivors fled to London, and exiled missions traveled to every country to call for a human defense plan, based in Fort Jun, the "heart of the world". Junbao is a good place, a node of communication between East and West.

Total Warfare Theory, Radio, Aircraft, Theory of Relativity, Nuclear Weapons...... Humanity's military technology develops faster under demonic threats.

It was not until after the victory in the North American War thirty years ago that the Human Defense Program announced the restoration of all of North America.

The long battle against the demons is not over. Innocent men and women are caught in a never-ending war against demons, and they are threatened by demons from birth.

A few witches can sing about escaping from the world and going to the spirit world, and many more will stay and suffer the fire of hell with humans.

The Nine Councils of Witches Left Behind have reached a cooperation with humans:

As part of the cooperation, the Witch should actively help the Witch create a "Witch Egg", breed the Witch's offspring, and continue the rare bloodline.

Zhang Su drove his Naihara Senjun pickup truck through the security checkpoint on the special highway to the foot of the wall of Dongzhou.

The 50-meter-high massive wall is truly spectacular, defending the gates of hell and protecting New Tokyo from falling again.

Separated by 300 miles, the men, women, and children of New Tokyo know that Mt. Kagura is protected by this impenetrable steel barrier, so they can sing and dance with peace of mind.

The main body of Dongzhou Wall is made of high-performance concrete, which can withstand a magnitude 10 earthquake unscathed, and the surface is coated with photocatalytic nano coating, which cannot be climbed and strengthens the protection at the same time.

The foundation of the rampart extends 50 meters underground and is reinforced with dense steel piles to prevent demons from tunneling.

Permanent warehouses have also been set up to store food, building materials and ammunition. It's an ideal fortress.

Barracks, warehouses, drone outposts, airfields, and heavy batteries surround the main building of the wall, and radar and high-altitude satellites scan the gates of hell on Mt. Kagura around the clock.

"Welcome to the Wall of the East Continent." An orderly took them out of the car and split up to find a place to settle down.

Shui Li protects Lianwu and goes to the barracks, and Li Yixin, Akasawa Yoshiyo and Robot Roy go straight to the training camp.

Zhang Su went to the headquarters to meet the commander, a school officer named Takagi Kiyobei.

"Please be seated, I'm Kiyobei Takagi, the commander of the Wall of Dongzhou." Kiyobei Takagi sat behind a steel desk, staring at Zhang Su with a bird-like gaze.

"It's rude, Colonel Takagi, I'm Zhang Su from the Anxin Asylum Shelter." Zhang Su bowed slightly.

"I have been ordered to push forward with the fourth extramural investigation." Takagi Kiyobei asked Zhang Su to take a seat.

Zhang Su looked at the other party.

He was about 40 years old, with black hair and grayish sideburns, a sturdy figure and a worried expression. Assault rifles, military uniforms, and family heirloom katanas hang from the surrounding walls.

[Memory "Takagi Kiyobei": The commander of the wall of Toshu, he has a traditional and serious temperament and aims to keep the wall safe from demonic aggression.] Both parents died as a result of demonic warfare, so they took the safety of their soldiers very seriously. Died 6 months later in the Kagurayama Rebellion]

Takagi Kiyobei will live and die with the wall of Dongzhou.

"If we can seal the gates of hell on Mount Kagura, we can save more innocent people." Zhang Su said.

"Merit is not a reason to die. In other words, Mr. Zhang is clearly the director of the detention center, but he has also experienced the battle? Kiyobei Takagi asked.

"It's not just the director, but now I'm listed as the supervisor of the local witch in Echigo, representing the local existence of the Witch Countermeasures Bureau, and the local witch should be controlled by me." Zhang Su said.

Strictly speaking, all the witches who are active in the area are under the management of Zhang Su, and he is the highest-ranking person in the Witch Countermeasures Bureau within the Kagura Mountain area.

"We urgently need the support of witches, and there are only a few witches in the camp who are not worthy of going to battle, and I am afraid that they are not the enemies of the demons." Kiyobei Takagi Road.

"I brought a witch who broke the position once, Yoshiyo Akazawa, according to the regulations, she can exert her full physical strength, and she can break the position when necessary." Zhang Su said.

"Isn't she a famous prisoner? But...... Also counted as a usable person. Takagi Kiyobei seemed dissatisfied with Zhang Su's answer.

He took out a strategic map and explained it in detail.

"The road to the gates of hell is divided into two areas, the safe area and the corrupted area, and each is divided half." "I'll make it clear, once you pass through the safe zone, you're half a foot in hell. ”

“…… I know very well that it's due to the effect of the Gates of Hell, right? Hell is colliding with our world, the reality of the Corruption is becoming unstable, space is warped, demons are infested, and we have no direct fire support. Zhang Su nodded.

The so-called safety zone is the area where the artillery and missiles in the wall of Dongzhou can play a role.

Once the boundary of the security zone is crossed, the wall of Dongzhou is useless, and the investigators outside the wall can only rely on themselves.

The atmosphere is dignified.

The sight outside the safe zone of the Dongzhou Wall is nothing short of a nightmare, but the safe zone is also shrinking, and as long as the gates of hell exist, it will continue to eat away at the real world, transforming the normal world into a part of hell.

That's why it's necessary to seal it completely.

"You are well aware of the risks. We will provide supplies, weapons and assistance to the soldiers, about a battalion, about 500 people. Takagi Kiyobei said slowly.

There are a total of 20,000 standing troops in the Dongzhou Wall, which belongs to the second army in the Dongming region of the Earth Defense Force.

Zhang Su nodded.

Six months later, 20,000 people supported the Kagurayama Rebellion for less than five hours, and the entire Dongming Kingdom fell into despair.

"I understand that according to the plan, we will first build an outpost in danger, which will be used to open a safe route from the wall of Dongzhou to the gate of hell and establish the first strategic stronghold." Zhang Su pointed to a location in the Corruption Zone.

The process of closing the gates of hell is well known, but few dare to work outside the walls across the safety zone.

Kiyobei Takagi thought deeply about it.

He slid a dossier across the table.

"This is our latest surveillance report that may be useful to you." There was a slight softening in his expression.

"Thank you." Zhang Su flipped through slightly.

While traditional monitoring methods are unable to penetrate deep into the Corruption, and most of the equipment loses signal in the unpredictable infernal gales, a small number of reconnaissance drones have managed to return, bringing back effective demonic intelligence.

The Demon Leader of the Erosion Zone is Irini, a powerful beauty demon.

Only demons who have reached a certain level of strength can have their own name.

"The work of the extramural investigation is very difficult, the previous three investigations only cost us more than 2,000 people, and the fourth time, it may also be futile, I can't stop you, but I urge you to reconsider." Kiyobei Takagi said.

Zhang Su and Takagi Kiyobei looked at each other.

"The fact that this work has been approved by all parties shows at least one thing: we all know how important it is to close the gates of hell. And something important, someone has to do it. Zhang Su said.

Takagi Kiyobei bowed to Zhang Su.

He stretched out his leather-gloved hand and shook Zhang Su tightly.

"You have courage, I admit it, although courage is not enough." He said, "Please rest for the night and leave on time tomorrow morning." ”

"Understood." Zhang Su saluted Takagi Kiyobei and left.

Coming outside, Zhang Su walked through the metal corridor.

For the fourth extramural investigation, go to the erosion area occupied by the demons, and establish a preliminary stronghold to facilitate the follow-up troops......

It's kind of some support, but it's not yet trusted. Zhang Su said secretly. The job was risky, but he didn't want to sit still.

He went to find Lianwu, because Miss Lianwu was most afraid of life, and if she came to such a chaotic place rashly, she might be too frightened to walk.

Zhang Su turned on his phone and sent a message to Miss Lianwu.

"Where?"

"East, top." Lian Wu replied briefly.

Zhang Su left the barracks and climbed the 50-meter-high Dongzhou Wall from a rumbling metal elevator inside.

Dressed in the Green Uniform of the Earth Defense Force, the soldiers are well trained and ready for battle.

At the top of the wall, Zhang Su walked along the aisle at the top of the wall, wide enough to accommodate two heavy armored vehicles walking opposite each other.

As he gazed out at the breathtaking demonic landscape in the distance, a cold wind lapped against his cheeks.

The lotus mist must be very cold,

Zhang Su soon saw Lianwu, she changed into relatively heavy clothes, wearing a brown and gray Patagonian windproof coat, slim jeans and white sneakers, which was very fashionable.

It was also the father of Lianwu, Mr. Hideyuki of Anxin Temple, who funded Dongzhou Industrial Company and eventually built the wall of Dongzhou.

The survival of this wall is closely related to the Anxin family, Zhang Su thought silently.

"Miss Lianwu." Zhang Su stepped forward.

"......" Lianwu walked on his own.

Shui Li looked at her from a short distance with her back against the wall, her blue hairband fluttering in the wind from the cold wind in the heights, and the mechanical arm was not afraid of the wind.

"The walls of Dongzhou are impressive." Zhang Su followed Lianwu, "There are similar defensive projects in other places, but the wall of Dongzhou is second to none in terms of grandeur. ”

Lian Wu didn't answer, just looked up at the metal guardrail on the wall, stretched out his finger, and gently stroked the lines on the wall, and the metal guardrail was covered with ripple-like weathered lines.

"I just met with Lieutenant Colonel Kiyobei Takagi, and he has a lot of confidence in the wall of Dongzhou, but he lacks confidence in the investigation outside the wall." Zhang Su said.

Lian Wu remained silent.

Her fingers lingered on a crack in the "high-performance concrete" and then tapped a steel support bolt.

Eventually, she even poked her head out and looked down at the vertical wall, as if to see where the base of the wall joined the bedrock.

"If Saho is here, I'm afraid I'll be scared to death at once." Zhang Su looked ahead.

The erosion zone is the place where the red cloud and gray fog are filled, and the farther away is the molten lava gushing and the remnant sun hangs high.

That is hell, part of which has intersected with the real world, and it is inseparable from each other.

It has a larger area than it seems, and any guided weapon will get lost once it is fired into it, so it will require manpower to enter the erosion zone, find out the situation, and establish a base inside.

Lian Wu continued to move forward.

As she walked, Zhang Su found that she had checked for flaws, and they were very clear flaws.

Stains, cracks, the rough edges of the concrete, they are carved into the giant wall like scars.

She often paused, leaned against the guardrail, and closed her eyes with a serious expression.

Soldiers along the way stood at observation posts and electromagnetic cannon points, ready for battle.

They didn't turn their heads to look at Zhang Su and Lian Wu, but silently watched the city wall for the humans behind them to resist the demons that might appear at any time.

But Zhang Su felt that they were a little strange, as if they didn't care about the work of the guards, and they were superficial, and even a little tired.

"Don't you think it's safe here?" Zhang Su asked.

Lian Wu didn't speak, she reached out, grabbed a piece of broken concrete, and pushed it forward hard.

It crumbled, and after a few pushes of the lotus mist, it shattered like a cardboard of paper, rolled forward, and fell all the way down the wall to the ground.

She looked to the other side.

Following Lian Mist's gaze, Zhang Su saw a hidden flaw, the turret itself had been slightly tilted, unable to withstand the weight of the central heavy artillery, and the connection was incomplete, making it difficult to withstand the demon's brute force.

Lian Wu turned her head and looked at Zhang Su sadly.

"Yes." Zhang Su sighed, "As you can see, we are walking on the largest tofu slag project in the history of Dongming Kingdom. ”

"......" Lian Wu shook her head.

"Once the demons invade, the damage to the walls of the East Continent will become known. Dongzhou Industry will become the biggest laughing stock in history, and its stock price will fall to the limit, so I told you at the beginning, don't buy Dongzhou Industrial shares. Zhang Su said.

When he first came to the wall of Dongzhou in his previous life, it had been trampled by demons, leaving it full of devastation. But Zhang Su now found out for himself that it was also broken when it was in good condition.

"......" a miserable smile appeared on Lian Wu's face.

How many times did she look at the black wall in the distance, fantasizing that this wall would keep the demons of Mt. Kagura out forever.

Could it be that Zhang Su eliminated the demon outside the wall, and the scandal on the wall of Dongzhou would disappear without anyone discovering it?
