The purification efficiency is more than ten times higher, this is the royal heritage, but Xia He glanced at the consumption, which was about five times that of his own design and construction, and he knew that there was still room for improvement. He directly threw the drawings to the Magic Academy in Sun City, and now that the Magic Academy has a number, the number of legendary mages is also there, and the progress in research ability is not half a bit.

And the academy and Cape Stormstorm are also in contact all year round, and when they get the task, they transfer the task to the academy in Cape Storm.

It only took two days of work for the improved version of the drawings to come out.

After Xia He saw it, after a little calculation, he knew that it was almost close to the fine products produced by the royal family, and there would be no big gap. But in terms of cost, it must be much lower.

Mechanical element construction, Xia He can produce it here in the New World, and soon he began to provide this equipment to the northern nobles and temples. His mechanical element construction has its own strengths with the royal family, and the nobles in the north have bought some on both sides. Not everyone has the ability to produce locally, and the cost of manufacturing and transporting it from the local side is not low.

To the east of the mountain range, the area occupied by the royal family is the richest place of mineral deposits, extending in both directions to the north and south, and the conditions of the mining area are getting worse and worse. However, compared with the area occupied by the emperor, on the whole, the mineral reserves in this north-south trending area are surprisingly high.

Xia He didn't need money, and all the nobles who bought mechanical element constructions and all other robots had to pay with refined raw materials.

It is not impossible to use ore, then the other party has to provide transportation.

The nobles were even happier, everyone needed gold coins, and if Xia He collected gold coins, they would not be able to make up for a while.

The sales on the royal family's side occupy almost the entire southern theater, and Xiahe's sales in the south are not ideal.

Fortunately, he didn't have that much capacity himself, so it was until September.

After all the nobles were ready, His Majesty the Emperor issued an order to attack. In the past half a year, the speed of the expansion of the Demon Domain has been extremely slow, that is, it is less than twenty miles, and the forces such as the Noble Temple, fighting on the edge of the Demon Domain, do not dare to go too deep inward, they have not exceeded fifty miles, basically in the area of twenty miles, and the casualties are large.

Therefore, the mechanical warrior sells very well, because this thing will not be polluted by demonic energy, although it will be purified after it comes out, it is because there is demonic energy residue on the body, but it will definitely not be demonized.

On this side of the Xia River, there is a war zone more than 300 miles wide, and it cannot be pushed flat. To the north, there are scattered fortresses in the Xia River and the temple, which are also more than two hundred miles wide, adding up to an area of nearly a thousand miles.

These are the two largest joint forces in the north, and no other family has been able to occupy such a wide area, more than a hundred miles, and as few as twenty or thirty miles.

On the side of the Xia River, the troops were divided into two routes, all the way close to His Majesty the Emperor's war zone, and entered close to the south. On the other hand, unite with the Shrine and enter with the Shrine army by leaning on the edge of the area occupied by the Dukedom. As for the further north, Xia He only arranged a small number of people to unite with other nobles and allow the other party to enter a hundred miles of his war zone.

The people who are willing to be on Xiahe's side have a good relationship, and Xiahe doesn't eat alone.

Approaching the front line of the emperor's war zone, Xia He handed over to Cotton Jack and asked him to lead part of the forces of the Third Field Army. Xia He himself took seven battalions of the Second Field Corps and stationed in the area of the Great Wall.

This is a super-massive battle, with more than 100,000 mecha fighters in one battalion.

On the side of the temple, there are more than 80,000 people in their own army, and there are more than 40,000 temple mercenaries, and the number of robot warriors is not as high as Xia He, but there are many of them, and the number of robots is close to one million.

The mecha soldiers are all mass-produced in alchemy factories, and they can be built with money, and quantity is not a problem.

Of course, Xia He is willing to act together, and the temple has ordered a powerful mechanical structure from him, the Angel of Dawn.

The materials of the Angel of Dawn are definitely of the legendary level, Xia He estimates that the temple has the means to strengthen it, and it must have been upgraded, and it is a legendary divine magic structure that can fly.

Don't look at the Dawn Angel is expensive, but compared to summoning a real angel, it is much more cost-effective.

Summoning angels requires a terrible amount of divine grace, and there is also a certain limit to stay. When an angel comes, his own power will be suppressed. It's better to consume a small amount of divine grace and upgrade the magic construct, which can fight in the army for a long time, also has a legendary level, and can also fly, and even release some powerful divine arts.

Xia He's attack on the Demon Domain was purely to destroy the Demon Clan, and any feats and the like were all by-products, which were not very attractive to him. He didn't want the demons to destroy this world, and his heart was quite pure.

So with the help of the power of the temple, it might affect his merits, and he didn't care.

The two sides have been working together for a while, and the combination of magician and magician is super efficient. Many nobles in the northern war zone secretly cooperated with the temple. The two sides were suspicious of each other, that was another matter, but when facing the demons, there was no such thing as a stab in the back.

The demons are the biggest enemy, and they are too strong.

In the previous war on the seaside, the nobles were still very proud, and the glory of mankind was maintained in their hands, but when they entered the Demon Domain, the casualties rose straight up, which calmed down the nobles.

It was during this period that there was more cooperation.

The commander of the Second Field Legion personally led the troops to the Great Wall Generation, first met with the head of the Temple Legion, and the two sides selected an area with a width of about thirty miles to enter the Demon Domain. This time it was not a small amount of cooperation, but a large army battle, which involved logistical aspects.

Xia He and Chang Quinoa have already negotiated, and the rest is the specific coordination issue.

There are seven battalions on the Xiahe side, and the first batch of forwards is only 6,000 people, but the heavy knights of this battalion, that is, the command center, will be a forty-four-level legendary great swordsman, and the deputy general will be a forty-level legendary mage. In the entire Second Field Corps, this battalion was second only to Sauron's general's battalion.

On the side of the temple, there was also a temple knight regiment of 3,000 people, a temple legion of 6,000 people, plus 3,000 mercenaries, a total of 12,000 people, and entered with this battalion in Xiahe.

The two sides gathered their men and horses, and the army slowly advanced, and when they reached the edge of the Demon Domain, a separate engineering force on the Xia River side dispatched robots to build a base at the edge of the Demon Domain.

A few hundred meters in front is the demonic domain shrouded in demonic energy, this camp is rapidly uprooted, there is a city wall more than twenty meters high in the front, the center is a tall magic tower, and then there is a fort, and the temple also has a special altar.

This kind of mixed chaotic architecture also appeared in the New World.

In the green forest, the area under the management of the temple is dominated by the temple, and the area managed by the dynasty is also difficult for the temple to be the master, and it is mainly noble.

Xia He and Chang Quinoa personally went to the front line and sat in this camp.

The walls of the camp are added with various anti-demon materials, and the entire area is double-covered, with magic and magic.

Chang Quinoa didn't care about his identity, and he and Xia He sat in the magic tower in the center, looking at the demon domain in the distance.

The following army deployments are constantly refreshed and demonstrated on the platform in front of the two people.

Chang Quinoa sighed: "Magic is really practical, it can let us know the dynamics of the soldiers below at any time, but it's a pity that magic is used too little in this regard." ”

"It's just that you don't care, magic can do the same, I've been to the technology world, these things are also necessary for the technology world. ”

"Thanks to the cooperation with the Duke this time, otherwise the casualties would have exceeded 50,000 by now. ”

"My side has also reduced casualties, you are welcome. ”

"If this war can be won, the temple plans to go to the Demon Realm to see, what does the Duke mean?"

"I don't have this plan yet, the Demon Realm is vast, and there are many worlds that have been invaded by the Demon Realm, so the power in my hands is simply insufficient. The temple controls more worlds, and the army is not worried. ”

"Then I hope that the Duke can provide technical support. ”

"For the Demon Realm, I definitely support it. ”

"Then it's decided?"

"It's decided. Xia He smiled. The ambition of the temple is not small, and it is a shortcut for the gods to improve if they want to invade the demon realm?

The Lord of the Dawn has always been known for its gentleness, but how could the nature of the gods change?

The coalition forces only began to enter the Demon Realm on the second day, and each side sent 500 men each, with a large number of constructed and mech soldiers. On the side of the temple, two giant divine constructs were dispatched to take the lead, and the dukedom was just a mechanical element constructs carried by the army, mixed in the team, and there was a separate purification chariot.

The two troops entered the Demon Domain, and the giant divine structure emitted a white light, dispelling the demonic energy within a radius of five hundred meters. Within three miles, the demonic qi had become sparse, and it was no longer in a state of being out of sight.

As soon as I entered, a monster appeared in front of me.

The gathering of the human army is not a secret at all, and the demons in the demon domain can see it clearly. It's normal for monsters to appear now. It's just that unlike the scattered monsters before, what appears this time is something that really crosses over from the demon world.

The beetle demon insect more than one meter long, with eight legs, has a hard back shell, two pairs of transparent wings, the wings stretch out from under the carapace, spread, and eight long legs run like flying.

The wings fluttered faintly, adjusting their angles like a speeding chariot.

The quantity is boundless!

A young female priest stepped forward, stabbed her scepter to the ground, bowed her head, and silently recited a prayer.

The whole team stopped, even the people on Xiahe's side. As if the demon worm in front of him did not exist, every soldier was in a calm mood.

A white glow lit up on the scepter, spilling in front of it, covering a thousand meters in width. Wherever the holy light passed, the wings of those demon insects began to burn, and the speed of running not only decreased, but even the balance was difficult to master, and many demons stumbled and rolled on the ground.
