Two battalions were left in Yamaguchi Castle, and the rest of the army marched slowly in a southeasterly direction in battalion units.

The nobles in the central part didn't build many good roads, and the demon domain created by the demons made the creatures in many places extinct, and there were many places where the demons artificially created demonized plants and animals. It's fine in the north, especially in the middle.

More than two hundred miles away, there is a forest with a width of more than a hundred miles, the vegetation is demonized, and there are some mutated animals, insects, and soil that are not suitable for the vegetation of the main world to survive.

Cotton Jack ordered the two battalions to open the way, and the demonized plants were also afraid of fire, and in front of them were large machinery to advance, cutting down trees, and letting the robots throw them into the forests on both sides. Then it was set on fire to make the road wider.

The pioneering behavior of the duke has always been simple and rude, anyway, these demonized plants will have to be eradicated sooner or later, and it is not a waste of resources to spend some energy to deal with them. If this land is not purified, the species born here will become more and more ferocious, and then spread around, threatening the survival of human beings.

In other worlds, the demons often get some demonized creatures to throw them over first, and slowly sit down, and some small worlds don't know how powerful they are, and they haven't been purified, and in a hundred or two years, the whole world will fall into disaster.

Large machines are cut with lasers, and the attacks of demonic plants are ineffective against large machines, and the propulsion speed is ideal.

Xia He really handed everything over to Cotton Jack and let him handle it. He and Xia Ye were both concentrating on modifying the data of various equipment drawings. In fact, the Taoist priests and magicians below have done the most work, and both of them are the final gatekeepers.

Some genius ideas are difficult to implement, because maybe the designer is a mage of more than ten levels, let alone a dozen levels, and epic mages have a lot of technical difficulties that cannot be overcome quickly. Xia He and Xia Ye, even to complete the final steps, it will take a lot of time.

On Cottonjack's side, he just made a general direction, calculated specifically, and Fire Raven No. 1 was also in charge, and then passed on all the details and handed them over to the following for implementation.

But the first time Cotton Jack commanded such a major battle, he probably had to mobilize millions of men before and after. It's impossible to say not to be nervous. He always pays attention to the battle situation, even the smallest details, and observes them personally.

In his room, the large phantom array was always open, and the battlefield screen was mobilized at any time.

The large metal machine, which is not too tall, only less than five meters in appearance, is just a multi-legged system, and the width and thickness are considerable. The metal arm structure is not an imitation of a human, but a kind of magic worm with excellent load-bearing capacity.

The laser cutter in front of the machine can cut off the big trees three meters in diameter at once, and the molecular oscillation knife removes the messy branches in the crown. A giant tree swings its branches and pulls them down at the metal machinery below. The metal machine also ignored it, and the calculation core automatically calculated the attack force, and the branch only made a slight scratch on the black metal surface.

It's not that construction robots are incapacitated, but their combat target is usually not an army, but a complex environment.

Cottonjack was lying on the bed, the picture adjusted upwards, and he saw that in the dark forest, there were demonic insects making a buzzing sound, converging in the direction of the troops.

Dozens of robots rushed forward, carrying huge fuel tanks behind their backs, and flamethrowers in their hands spewed flames tens of meters long. The demon insect born from pollution was incomparable to the demon insect of the demon world, and it was burned on its body by a thousand-degree flame, and it suddenly fell to the ground.

The body that was still burning, constantly bouncing and twitching, and the ground was also ignited by demon insects. These liquid fuels cannot be extinguished when they are attached to the body, and the flame will continue to burn.

Behind the construction machinery unit, there are robot warriors and human-controlled combat vehicles.

Cotton Jack frowned, the speed of advancement was slower than expected, and it could only advance about four to five miles in an hour. There are a lot of construction robots sent this time, and it is so difficult to face the forest. If you rely on human infantry to advance, I don't know how much danger there will be.

Those demonized plants are more troublesome than the dryads raised by half-elves. After all, there are not many dryads, and in this forest, every tree is demonized.

Microrobots are collecting samples, and the materials of these trees have become particularly tough and have a certain amount of magic defense. At the same time, the branches are activated, and the attack power is nothing for huge construction machinery, but for infantry, it is possible to hurt the soldier's neck.

Some construction robots weigh hundreds of tons, and they won't shake if they are pumped. Human soldiers are only more than 100 catties, and some sturdy ones may be more than 200 catties, but is there a difference?

Only heavily armed warriors can resist such an attack, ordinary soldiers, the magic array on the armor stopped working, and the weight was only more than fifty catties.

Smoke and fly!

The armor of ordinary soldiers is against light weapons and magic muskets, and when they encounter heavy hammers and battle axes and the like, they are smashed on the head, even if the neck part is supported by an external metal spine, it depends on luck if it is broken. If you don't smash it, you can still survive the unloading.

The armies of these nobles are also a squad of five, but the heavy armor of the squad leader, the additional magic is not the phase frost dragon shield, but the air shield, which is more popular in the wizarding world.

The air shield is actually wind element magic, and its defensive power is not as good as the phase frost dragon shield, but after being penetrated, it will not collapse, and the broken position can be quickly repaired automatically.

The high-level air shield, like the phase frost dragon shield, has a complex internal structure and can deflect enemy attacks.

The important thing is that the excitation and existence of this thing are less than the consumption of the Phase Frost Dragon Shield. Xiahe's own main force is not too concerned about the cost of use, although it has been considered when designing. But the equipment of each soldier, in fact, has been optimally optimized.

The army is moving forward in squadrons, following the mech troops, and the mech warriors are also covering on both sides. There are also small special robots, such as mechanical spiders, that operate in the forest that has not yet been cut down, and are responsible for keeping watch.

The mechanical spider, which is a more satisfactory mechanical body designed by Xia He, walks quietly in the forest, and eight metal mechanical feet bounce silently on the ground and tree trunks.

Cotton Jack's image only shifted for a moment, and he stopped paying attention to the small special robots on the periphery.

Airplanes......

Huge beetles flew on the side of the forest, listening to the sounds, and there were hundreds of them. They relied on their sense of smell to act, ignoring the cyborg troops in front of them, and pounced directly on the human soldiers.

The cyborg warrior on the side immediately raised the magic musket in his hand, and the auxiliary metal eye was also opened, and the muzzle of the gun was aimed at the forest that was still burning on the side.

On the ground, a mechanical spider suddenly jumped violently, this jump was more than eight meters high, and it pounced on the body of a demonized beetle. The beetle's slender body was more than a meter long. Inside the sharp mouthparts, there are also dense small teeth, which look like the tips of needles.

The metal spider's forelegs were staggered, and in a flash of cold light, the head of the demon worm was cut off. From the inside of the wound, a dark green liquid is sprayed. The liquid spilled on the ground, making a sizzling sound, and the accumulated fallen leaves were corroded into a hole.

The metal spider let go of its legs, and a demon worm from behind it had already swooped down on it.

The metal spider directly spewed out a web, the size of which could easily encircle an adult man in armor. The demon worm slammed headlong into the net, and the net immediately contracted, its wings were strangled, and its body lost control, rolling forward, and falling to the ground.

The metal spider also fell, and when it landed, it made a crashing sound, and then rolled on the ground, burrowed into the fallen leaves, and disappeared.

The demon worm in the air hovered down, looking for the whereabouts of the metal spider.

A dozen or so small robots hiding behind the trunk of the tree fired lasers at the same time on their backs, knocking the swooping demon insects into a scorching smell.

The energy of the small robot is not sufficient, and even such a weak laser attack will run out of energy in a few clicks.

It's just that these lasers contain light element information, and the enemies that are hit can be detected by the army of the Duke of Xiahe. These small robots were originally on guard, whether they could kill or injure the enemy or secondary, they were too small, and they did not have the sharp forelimbs of mechanical spiders.

The battalion general of the previous battalion had given an order at this time not to go deep into the forest at once, and now a few miles of road had been carved out, and a battalion was piled into it, which was not conducive to defense.

Bang!

The robot's musket fired, and there were already beetles flying into the burning area, which was a slashed demonic plant that the robot had thrown over, and when the beetle flew over the burning area, it was already on fire.

These beetles are large and much more powerful than the demon insects that appear in front of them.

"Mind you, it may have been raised by people. The battalion will be alerted, and the soldiers below have all raised their weapons one by one. The squad leader is ready to activate the magic shield on his body at any time.

The battalion general is also aggrieved, in the north, this kind of demonized forest has long been dealt with, and there are more powerful mechanical troops on the duke's side, so they will not leave this kind of trouble. Now that the Great Wall has passed, a large area of forest has appeared, and what have the nobles in the central part done?

The width of the road, which is about 50 meters, is covered by two ancient trees, plus even lower forest shrubs on both sides. Fifty meters wide, just in the formation of the squadron, there is still room to arrange the robots on both sides of the defense.

Fifty meters away, there were also low shrubs, which had been laser-cut so that only a small section of the ground remained.

The trees that were dragged into the depths of the forest burned a hundred meters away, and the magic flames seemed to be very heavy, and the smoke and dust from the burning fell directly to the ground, not affected by the driving force of the hot air at all.
