In Northrend, most of the region is extremely cold.

Duke did not know under what conditions the historical Silver Crusade had organized its army. He only knew that even if he had made so many preparations for the battle against Northrend, all kinds of cheating situations were still emerging.

However, there are many soldiers in the alliance.

An old dwarven soldier taught the recruits: "Let me tell you that the commander of the Alliance, Duke Marcus, is the commander of the most knowledgeable soldiers. If it was before, you would have had to wear torn leather boots, and when your toes freeze black, your toes will be dead and useless. Now it is a collection of animal skins imported from the tribes, plus cotton boots made of cotton to protect your feet. ”

Cotton boots, padded jackets, spiked shoes, snow tracks, military rations and hot soup that can be heated by pulling the line, and even Duke strictly ordered that the toilet must be connected to the barracks, because if a soldier leaves the barracks in the middle of the night to go to the toilet, even if the toilet is five meters away, he may freeze to death because of the snowstorm and cannot find the way.

All the details reflect the meticulous preparation of the alliance for this Northern Expedition.

Normally, if you sleep in such a cold and snowy terrain, even if there are tents, many soldiers may never wake up the next morning.

Not dying on the battlefield, but dying in an unknown place, is quite demoralizing.

But with the introduction of simple hot kang heads and new movable central heating, non-combat losses for soldiers camping in the wilderness have been reduced to single digits for almost every regiment.

Varian led the Alliance army into the Howling Fjord, and fewer than 10,000 people in history have been able to reach Utgard Castle. It's not that the alliance and the Horde don't want to commit more troops, it's that the logistics can't keep up at all.

Now it's a different story.

The Sky Fortress Naxxramas opened the way, and the Alliance forced its landing on the shallows on the east and west sides. Huge conveyor tracks were then erected on the shallows, driven by diesel engines to transport boxes of military supplies to the Howling Fjord plateau, which was tens of meters high, while ordnance such as soldiers and heavy tanks were transported back and forth by large elevators.

Watching a group of soldiers burn the lower part of the diesel engine with a pre-prepared fire, Varian just had a feeling of being out of the blue.

He smiled wryly, "Could it be that Uncle Duke really has the ability to predict the future?"

Once upon a time, Valilla always played the role of cheering, encouraging Varian, saying that he could surpass Duke, but after getting along for a long time, Valilla couldn't say: "Maybe......"

The alliance popularized the diesel engine in the past few years, and the steam engine could not operate in extremely cold weather, so it was tested. But it's hard to gauge how the diesel engine would behave in a hellish place like Northrend.

After all, there are not many extremely cold regions on the Eastern Kingdom Continent, even if it is the ice-covered Lockmodan or the former Alterac, the weather is only a few degrees below zero. There was no military adviser or staff officer who asked how to start a diesel engine that had been completely sealed in frost at minus 40 degrees.

When the problem arises, most of the Alliance legions are desperate. If you leave out the alliance's technology side products, this means that you can only rely on the most primitive infantry and griffin knights and other air forces to fight.

Fighting like this, the casualties of the alliance are absolutely large.

Who knew that the question was sent, and within two minutes Duke replied, asking them to set up a stove under the engine to roast.

It sounds ridiculous, but during World War II on Earth, both the Soviet and German armies did this in extremely cold weather, otherwise even if the soldiers smashed the ice slag on the outside with a hammer, the inside would still be frozen into a lump of ice, and they couldn't move at all.

If you want to roast, how far will it go?

Answer: "When the ice melts, the outer armor starts to turn black, and the rest is given to antifreeze oil." ”

Simple violence, a connotative solution, that's it.

Everyone knows that Duke has never been in the snow for the first half of his life. What even the dwarves can't do, he can do it. Not only do you use a roast fire to deal with frozen machines, but you also have antifreeze oil.

People can only try a better formula after thousands of trials, Duke is good, this side of the project, that side has given the result formula, you can do it for me.

One by one, black technology was smashed out, smashing the dwarf and dwarf inventors into a daze.

Gerbin complained more than once that Duke would have ruined their scientists by doing so.

Duke shrugged: "It won't take ten years for the Burning Legion to make a comeback, and I can't help it! Or if you make the Burning Legion late, I'll give your scientists more time to practice?"

Gerbin had nothing to say.

It was under such strong modern equipment that the armies of the eastern and western fronts, almost advancing while laying railways, with a momentum like a bamboo, would be under the castle of Utgard in just over a week.

The army of the Eastern Front directly set up heavy artillery across the Imiron Falls to the east of the castle, while the main force led by Varian on the Western Front lined up the orc infantry corps of Little Sarufar while setting up the cannons.

This is both a deterrent and a deterrent.

The bombardment of 155mm heavy artillery left the fortress of King Imiron, the boss of the Viku people, completely damaged in just a few minutes. A castle that has not been reinforced by a magic protection circle is a large target in the eyes of the Alliance gunners.

The city that the Viku people spent ten centuries building was torn apart in a matter of minutes by the Union cannons.

"Air Defense Ready!" Varian held aloft his twin swords, the Shadow Ripper and the Shadow Marauder.

As expected, a steady stream of gigantic Vekus, with their half-giant blood, poured out from behind the castle's shattered walls, spreading their feet and swarming into the Alliance and Horde forces in a disorganized formation.

The Viku are loyal to their King Imiron, and although the Orcs always say that they are a race made to fight, it seems that the Viku are more worthy of the title than the Viku.

If it was simply a Giant-Race Veku, it wasn't enough for the Alliance to take it so seriously. The real name of these Viku people is the Dragonsnatcher Clan.

Unlike their five-colored guardian dragon relatives who have been given some power and intelligence by the Titans, these beasts are the most common Archaeopteryx, which has no magical constitution and is slightly less intelligent, and is technically a standard dragon beast.

They don't have the long necks that protect their distant dragon relatives, they have shorter tails but larger heads, and mouths with strong jaws that make up more than 40% of their heads. The wings are very powerful, but the front legs are almost completely degraded. When not flying, the wings play the main supporting role for the body. The hind legs are stout and are the main tool for predation. The whole body shape tends to be more adapted to the streamlined shape of flight than that of the guardian dragons.
