Renault made several one-centimeter-thick steel plates, each one meter square, the largest size a mobile phone could make at the moment, and then she asked Vivi to try to put them together. Pen ~ fun ~ pavilion www.biquge.info

A small black mist slid through the gaps, and several steel plates were integrated, just like the whole steel plate.

This is the magical power of the 12th Demon Spirit Fusion, which can put anything together perfectly, as long as there are enough materials, it is not a problem to build a spaceship.

Of course, Weiwei is not very skilled in manipulation now, and too much time is the biggest problem at present.

Renault built another cage out of steel bars, and the demon rat he brought back yesterday was still tied there, just to try which was harder, his teeth or the steel bars.

The caged demon rat looked very angry, but whether it was biting wildly with its sharp teeth or scratching with its claws, it could only leave a few scratches.

In this way, Renault was relieved, and he couldn't help but be happy and rejoicing.

Demon rats have appeared in the mine and Black Iron Town, and the nearby mines are already very unsafe, and there may be hundreds of demon rats hidden.

After discovering the demon rat, Luo Xi immediately blocked Black Iron Town, probably not wanting to hand over the mine to the temple to seal it, and planned to deal with these demonic beasts by himself.

But does he have that ability?

Demon rats are not very high-grade magical beasts, but they are incredibly numerous, ferocious, and easily infected with plague, and every time they appear, it is a disaster.

If Roshi can't stop these demon rats, not only will Black Iron Town usher in a catastrophe, but it will also affect Renault. When the temple gets the news and sends someone to come, I'm afraid that the people will already be dead.

Without Vivi's demonic powers, Renault would have had to take everyone to take refuge elsewhere, but not now.

His mobile phone can make steel plates indefinitely, as long as he makes reasonable use of manpower, there is no problem in making more than a dozen tons a day. Then add Vivi's demon spirit, fusion, and soon build a sturdy steel fortification.

After careful investigation and calculation, Renault decided to make a large iron bucket with a diameter of 30 meters, located at a three-way intersection not far away. This requires about 1,800 one-meter steel plates, all calculated according to the thickness of one centimeter, totaling more than 140 tons, and nearly 500 tons of ore.

For a world without construction machinery, this is a huge project. Fortunately, there has been no business in the past few months, and the mined ore is piled up at the foot of the mountain, which is enough.

Everything is ready only to the east wind, Renault threw the quill on the table, relieved, this drawing drawings is too inefficient, and when it is free, the first thing that must be made must be a pencil.

He doesn't understand architecture at all, and the drawings are drawn casually, calculate the data, anyway, it's an iron bucket, just have a rough appearance, I believe that a centimeter of steel plate surrounded by five meters high, how will it not collapse, and it will be a big deal that he will personally construct it on site at that time.

Time was of the essence, so Renault had the underground warehouse renovated first.

The underground warehouse was directly below the hall of his house, and he had two holes dug in the floor of the hall, one with a funnel so that the ore could fall straight down. A gallows was attached to the other hole, and the steel plates were made and hoisted up with a gallows to carry away.

In this way, a simple assembly line was built.

At first, the miners felt very magical, they didn't know what mysteries were hidden in the underground warehouse, so much ore could not be filled, and they kept transporting steel plates. It wasn't until they saw Vivi fuse the steel plate into a single piece that everyone knew that it was the power of the demon spirit.

As a result, everyone was in awe of Renault, and the double salary also made everyone full of energy. Renault had planned to finish the steel plates in five days, but it took only three days to complete them, and with Vivi's efforts, the floor of the large iron bucket was also spliced.

He came to the construction site, and there was a large round board with irregular edges on the ground. After three days of non-stop use of the Demon Spirit Ability, Wei Wei also looked quite tired. But at the same time, she is in a good mental state, perhaps because she can finally tie up Renault's busyness, and she is no longer a little maid who can't cook well.

It's just that Lauren took people to fight the steel plates here for a few days and felt very puzzled: "Lord Renault, I really don't understand, you use so much high-quality steel just to lay a floor in the field, this is too wasteful! These steel plates can be sold for at least thousands of gold coins!"

Renault smiled, what was the use of more gold coins when he didn't have his life, and when he knew what this thing was really for, he wouldn't feel wasted.

At this time, the convoy sent by Momiji to deliver food came, a full ten carriages, four more than Renault expected. After reading the list, Renault realized that the price given to him by Hongye was three copper coins per catty of grain, which was two copper coins less than the market price in Black Iron Town, so it cost thirty gold coins, and Renault got a total of ten tons of grain.

Picking up such a big bargain, the favor is owed, and it seems that after this incident passes, I will go to Sequoia Town in person.

Thinking of this, Renaud asked Lauren to immediately set off for Sequoia Town with the remaining ten gold coins, the purpose of course, to buy saltpeter and sulfur. Although with the big iron bucket, defending against the demon rat is no longer a problem, but Renault is not willing to shrink into the big iron bucket and wait for the temple to send someone to save him. Not only did he have to defend, but he also had to fight back, which would require more powerful weapons.

After Lauren and the people left, Renault made several small warehouses in the middle of the iron barrels, poured all the grain into them, and covered them with wooden planks.

Then the construction of the fence was started, and the miners were allowed to build improvised shelters, public canteens, and most importantly, toilets in large iron barrels, and to collect large quantities of wood for fires.

In addition to leaving gates in the direction of each intersection, he also deliberately left some small holes, and then installed a sturdy steel cage inside. If the rat gets into the cage, the people inside can use a spear against them.

The five-metre-high wall was erected in just two days, and Renault added a two-metre-wide platform to the four-metre-high position and made a triangular diagonal brace with thick steel bars, so that the fence was impregnable.

Touring around the platform, Renault found another serious problem. There are at least 300 miners and their families, and they eat, bathe, and go to the toilet every day.

The usual domestic water is brought back by Lauren in a horse-drawn cart to the creek at the foot of the mountain, but once besieged by demon rats, who would dare to fetch water?

He couldn't find a good solution after thinking about it, so he went to Badge to discuss. Bhaji told him not to worry, because in ten days at most, snow would begin to fall in the West, and it would continue until next spring. If Renault plans to live in a big iron bucket all winter, he will have to clear the snow every day.

Baggy's words reminded Renault that he had not thought about drainage at all when designing the big iron bucket. It's fine if it snows, but when it rains, it's troublesome.

Rubbing his aching temples, he has worked hard these days, and there are too many things to consider, and it is inevitable that some omissions will be missed. But now there is no time to remedy it, the fortifications are basically formed, and the next thing he should think about is the weapon.
