In order to win, Friedman needed to centralize authority. In order to survive, Bishop needs to get rid of the disobedient nobles of the Banshee Castle. In order to make money, the nobles and wizards of the Banshee Castle teamed up to bring Powell to the forefront.

But when Powell disguised himself as a corpse collector and took a carriage transporting seriously ill patients to Dense Fog Town under Adrian's surprised attention, Zhou Qingfeng was arriving outside Dense Fog Town with an engineering team.

It's a peculiar team, a hundred kobolds plus five hundred human laborers. They were transported by more than 100 heavy wagons to the outside of the town several times, and after unloading tools and materials, they began to build improvised houses and survey construction sites.

Due to the severance of trade routes, hundreds of caravanserans gathered in Dense Mist Town. They desperately hope that Coldwind will send a powerful army to open up the trade and transportation routes.

As a result, an engineering team came.

The arrival of the leader of the team immediately aroused onlookers.

People stood outside the construction site and exclaimed, "Look, it's kobolds." This little monster in the dark dared to come out during the day. What do they wear on their eyes? It's weird stuff. ”

The construction site was marked with lime, and the townspeople crowded out of the lines with great novelty, pointing and pointing.

Skinny kobolds are not used to being watched in broad daylight. They dodge dodging dodge. But with His Excellency the lord personally supervising the work, they were at least not too afraid.

Due to their extreme weakness, some people in the town habitually throw stones at the kobolds, deliberately bullying and even expelling them. In the past, it was only swallowed, but now the person who threw the stone and spat will be pulled out and smoked.

After a few terrible screams, no one doubted Lord Hugo's determination to engage in racial equality—a kobold who knew engineering was obviously more valuable than an idiot who couldn't read a word.

During the time when Powell went to the Banshee Fortress with the magic potion, the kobolds living in various parts of the Northland heard that a human lord was willing to contain them, and they tentatively sent some emissaries to see the situation.

After confirming that Coldwind was willing to contain harmless races, there was an endless stream of kobolds who arrived - this kind of people are small in individual strength, so they are particularly adept at using tools and building fortifications to protect themselves.

As the number of kobolds increased, the engineering strength of Coldwind City skyrocketed, and Zhou Qingfeng decided to implement his long-planned offensive and defensive strategy in advance.

Build military forts on the main transportation routes around Coldwind City to avoid the enemy's long drive and provide convenient logistical support for future military attacks.

The north is so big that there are hundreds of kilometers between cities. Even in the real world, an assault by armored forces for one or two hundred kilometers is an extremely risky operation. Only big countries bully weak chickens to do this.

Now that the family has a big business, Coldwind City can't allow the enemy to appear under its walls at every turn. In order to carry out a big project in the cold winter, Zhou Qingfeng also used an artifact that can change the world - explosives.

In order to fuel the furnace body, Alsie's coke oven has to dry distill dozens or hundreds of tons of lignite every day to increase its calorific value. As a by-product of dry distillation, the production of various magic potions is also particularly large.

The spirit slaves were too busy in the alchemy workshop, separating and refining magic potions from the crude products of coal tar and wood tar every day.

Through the repeated selection of Wizard Jason and the addition of stabilizers to ensure safety, the workshop can obtain about half a ton of explosives per day.

As an alchemist, Jason has seen a lot of explosive items, and he doesn't realize that there is anything special about the explosives he accidentally discovered. But Zhou Qingfeng cheered all day when he heard the news.

There is no other ......, cheap, large quantity, and enough.

Although this magic explosive can be used in battle, it doesn't matter if it is used in engineering. It doesn't matter if it produces highly toxic smoke after exploding, just dissipate naturally in the open area.

Zhou Qingfeng deliberately brought a few tons of hoarded explosives to Dense Fog Town, and the first thing he had to deal with was the environment that was frozen to the hard ground in the winter - the ground was as hard as iron, and there was only a white spot under the pickaxe.

The kobolds spent one day surveying and selecting the construction site of the fort, and the next day they drew a lime white line on the ground. As for the reason why they can come out and work during the day – it's simple, wear sunglasses.

Stalls, ten pieces and five pairs, the amount is preferred.

Zhou Qingfeng entered a few hundred pairs in one breath so that the light-phobic kobold could come out during the day and work with human laborers. This greatly improves labor efficiency, after all, it is very difficult for many manual labor to rely on kobolds.

The residents of Fog Town are also extremely curious, they can't figure out what such a group of kobolds from outside the town does.

The little monster made holes in the ground, and took out cylindrical things from the wooden boxes brought by the carriage and stuffed them into holes.

What is this mysterious thing to do?

A bunch of people were full of question marks and speculation. When many people heard that the kobolds were coming to build a fortress, they laughed even more, and found it unimaginable.

Before they could figure it out, the human laborers who maintained order began to clear the site. Residents asked, what the hell are they going to do? They don't say it directly, they just answer for a while.

Only one explosive was placed in the first gun, and all personnel retreated to a distance of 100 meters. The kobold pulled out a half-meter-long fuse, lit it, and fled quickly.

The onlookers couldn't see clearly from a distance of 100 meters, and they put their heads on the outside of the blockade line, talking to each other, very curious. But when the fuse burned out, there was a thunderous sound from a hundred meters away!

The do-gooders were frightened and all scurried and scurried against each other like headless flies. Most of the people ran and fell down, but they didn't care about the bleeding from their heads, they got up and continued to run, and they stopped after running a few hundred meters away.

There are even worse farts and urine, falling to the ground crying and even fainting on the spot, which is extremely humiliating. Only the laborers who had experienced it laughed beside them, not mentioning that they themselves had been frightened by the explosion.

Each borehole was one meter deep and two kilograms of explosives were placed. Although the explosives were of average power, they blasted through a large crater about one and a half meters deep and four or five meters in radius on the hard ground.

The pit was a crumbling clod of earth, which could be dug up with a hoe. This is much easier than burning the ground and costs and time is greatly reduced.

Relying on the explosives produced by this alchemy workshop, the speed of the recent construction of water conservancy and irrigation projects in Cold Wind City has greatly increased.

In the past, hundreds of people could only dig 50 meters of shallow ditches when they were tired to death a day, which was still extremely tiring and heavy physical work. Now the same labor can dig deeper, longer, and easier.

The kobold engineering team rushed to Dense Fog Town, and carried out dozens of ground blasts on the same day, completing a volume of work that used to take a month or two to complete.

Discovering the power of the explosives, the townspeople go from extreme shock to extreme curiosity. They crowded around the construction site again, covering their ears every time they lit a gun, but they didn't leave.

When the cannon goes off, hundreds of do-gooders will compete to chant, attracting more people from the town to come and watch - such free dramas are not watched in vain, and people talk about and gossip endlessly.

By the time Powell arrived in Fog again, the foundations of the fort had been almost blown up. He shook off the wagon and walked into the town on foot, and when he heard the townspeople greet each other with a smile on their faces—did you fire the guns today?
