North of Orgrimmar, east of Ironforge Castle, north of the forest edge of the mountain pass.

There is a trail of felling in the woods here, and looking down from the air, it looks like a piece of green bread has been bitten hard.

In the open space of the gap, there are also several thatched huts that look dilapidated.

A few years ago, the first "lumber yard" was built here, and the earliest timber in the territory came from here, but after the discovery of the "Iron Fort Fort", the entire lumber yard was moved there for unified management, next to the "quarry".

At that time, the thatched hut was left as a resting place for the Spider Rider Patrol.

These thatched huts are also the products of the system, and even after a few years of wind and rain, the exterior is tattered, but the inside is still intact, and it happens to be a resting place for the logging brigade now, well...... It's a little smaller, but it's better than nothing.

Today is the second day of the formation of the logging brigade.

In the woods directly in front of the hut, a large group of green-skinned orcs and goblins were like locusts passing through, wielding a variety of weapons in their hands, cutting down the trees in front of them in various ways, and then uprooting them and piling them up in the clearing.

Inside the hut, Stone is explaining the next precautions to several leaders, including the "Flag Bear" Big Bear, the "Brawl Boss" Kicking Teeth, and the two new champions of the Big Gymnastics Championship, Simu and Mogru.

He won't stay here all the time watching the boys cut down trees, the more important matters of the territory are waiting for him to solve, this kind of unskilled work has the leaders to watch, but the premise is to explain clearly.

What the leaders have to do is very simple, that is, to keep an eye on the boys under their command and not to run around, just follow the gap left by the hard workers in the timber yard before, go all the way to the north, and cut a passage seven or eight meters wide, as for the specific location of the city wall, wait for a few days, the stone will take the time to come back to check, and tell them when the time comes.

After making sure that the leaders had memorized it, Stone took two barrels of beer from his ring and threw them at them, and then ran back to Ironforge to prepare materials for the future construction of the wall.

Now the manpower and material resources of the tribe are not comparable to before, so this time he decided to do it in one step, what earth walls, wooden walls are not in the scope of consideration, and directly mount the strongest and most time-consuming stone wall.

Nowadays there are quarries in the territory, mostly stone, and even simple processed strips of stone, which are very suitable for the construction of city walls.

But the stone was not intended to be made of stone alone, and in his plan, the main force for the construction of the city wall in the future would be those who were hard workers, for whom the weight of the stone was too large, and if it was built a little higher, the difficulty of the project would be greatly increased, and it would be time-consuming and labor-intensive.

After pondering for a long time, he finally came up with a perfect solution, which was to build a city wall mixed with brick and stone by referring to the famous miracle building in China in his previous life, the Great Wall.

The so-called masonry mixed wall, is the following with ordinary stone as the foundation, they bear good load, but also can resist natural erosion, etc. is the most suitable for laying the foundation, and so on the stone stacked to more than one meter high, the top began to lay bricks, the size of the bricks is small and light, the use of flexible and easy to construct, so the masonry is on the upper floor.

This kind of city wall is not only solid in structure and extremely resistant to all kinds of cold weapons, but more importantly, it is easy to construct and can be easily built very high, especially suitable for those who are only a few tens of centimeters tall under the stone men.

However, in order to build this kind of wall, in addition to the ready-made stones, there are two key materials that need to be solved, the first is the bricks for the wall, and the second is the adhesive that binds these bricks and stones.

Both of these materials require technical content, so the stone immediately thought of the technical talents of his own territory, the Chaos Dwarf Xueba, Ayigunu Golden Lock.

As soon as he returned to Ironforge, the stone rushed directly to Ayigunu's room, ignoring the little bell's surprised gaze, and led the Chaos Dwarf to the stream outside Ironforge.

Ironforge is located in a valley with a meandering stream next to it.

Although I haven't read much about stone, the most basic common sense is that you need clay to make bricks, where to find clay? Dig on the bank of the river, of course.

Along the way, he told Ayigunu about his idea of building a brick wall, and the latter immediately showed great interest, and her recent days as a teacher had been too boring for her.

When she heard that the leader would build a masonry wall from scratch and then gradually expand it into a fortress, she immediately activated the technical gene in her heart and volunteered to be the chief engineer of the entire project.

The stones, of course, are desperate.

Sure enough, as soon as the connoisseur made a move, he knew if there was one.

Under her guidance, the two quickly found a suitable clay by the river, which, according to the scholar's professional statement, has little sand, reddish soil, and is full of stickiness, which is very suitable for burning bricks.

The stone immediately made a decision, built a brick kiln next to it, and took soil to burn bricks nearby.

Ayigunu has no opinion on this, and she also knows how to repair the brick kiln, but she also raised a question.

If you want to make enough strong and durable city wall bricks, then these clay digging out, can not be used directly, to go through up to half a year of wind and sun, wait until the interior is naturally loosened, and then manually crush and screen, and then select the fine pure soil can be used, with the treated clay, you can start to make bricks and burn bricks, the whole process may take more than half a year.

She was also impressed by the stone, but he decided to burn the simplest batch of bricks before the first batch of suitable clay was completely dry, which he was going to use for experiments.

As for the bricks for the city walls, he asked Ayigunu to make a kind of cyan brick.

This is a type of brick unique to Huaxia, which is more troublesome to manufacture because it needs to be manually poured with water to cool down during the firing process.

Having traveled to the Great Wall in his previous life, he knew that blue bricks were stronger than ordinary red bricks, and this kind of brick was used in many city walls and passes in ancient China.

Now that he knows the principle, Ayigunu also said that there should be no problem, that is, a large number of qualified workers are needed.

For this reason, the stone also made a bloody investment, and all the fart laborers in the territory were mobilized, and they left the "quarry", "lumberyard" and "garbage dump" where they had worked, and gathered together to be at the disposal of the Chaos Female Dwarves, a total of 1,500 people.

Their original work will be replaced by lower-level fart slaves, and although their efficiency will be greatly reduced, there is no way, and only they can do the brick-making and more complex work that follows.

Stone has sent someone to inform Old Rotten Tooth to suspend the transformation of the fart tyrant while keeping the mushroom field running, and send all the remaining fart slaves to Ironforge to replace these laborers.

After these little cabbage heads were promoted to hard labor, they did very good manual work, neither as clumsy as the orcs, nor did they want the goblins to be so clumsy, the key is that they were easy to raise, and they were very satisfied with any leftovers, and they were very suitable for the work that did not require a lot of physical strength such as burning bricks.
