Han Cheng has already made his choice regarding the location of the furnace in the Tongshan residential area.

There is a relatively flat land between the copper mountain and the tin mine, which is where the furnace will be built.

Generally speaking, when building an industrial zone that requires a large amount of raw materials, the factory will generally be built in the raw material production area. Some factories will also be built in places with convenient transportation.

The Qingque tribe will now come here to develop the same residential area as above, which is oriented towards raw materials.

The furnace was built at the foot of Tongshan Mountain, close to the mountain and slightly far from the tin mine. This is because when smelting bronze, the consumption of copper is generally large.

By building the furnace here, people only need to pour the excavated copper ore down the hillside, which is very convenient.

When preparing the stove, Heiwa gave a suggestion. He thought that they should first build a small wall outside the Tengshe tribe’s cave. After all, the people of the tribe would live in this cave for a long time.

The people of the Qingque tribe have long had a deep understanding of walls, so now as soon as they settle down outside, they want to build walls or protective measures similar to walls. Without these, they always feel insecure.

Heiwa's suggestion is actually almost the same step that the Qingque tribe took when they first became rich. They first built a wall outside the cave to enclose everything, and then slowly built houses inside the wall and let people move out to live in the houses.

This method certainly had no problem in the past, but it is not applicable to the Tongshan residential area.

There is no doubt that the most important things in the Tongshan residential area are copper mines and tin mines, so the buildings must be centered around these two things, or around the furnace.

The cave of the original Tengshe tribe was about four miles away from the place chosen by Han Cheng for the panluo.

This distance is OK for a short period of time, but it won't be suitable for a long time.

One reason is that once the copper furnace is burning, it will generally start to refine copper 24 hours a day, day and night, and someone must be on duty at all times. It would be inconvenient if the residence is too far from the copper refining place.

The second is the safety of the furnace and the people who smelt copper.

The nature of copper smelting, which takes place day and night, dictates the need for a two-shift or three-shift system, which means that it is impossible for all these people to work at the same time.

The distance between the residential area and the copper smelting place is too far, which will lead to the dispersion of manpower. It would be fine if we don’t encounter the enemy on weekdays, but once we encounter enemy attacks, it would be quite dangerous.

Thirdly, for the safety of personnel, a wall must be built around the furnace. In this way, two walls need to be built.

This is undoubtedly very labor-intensive and time-consuming.

So Han Cheng’s idea was to put the industrial area and the residential area into the same large courtyard, where people could live on one side and smelt copper on the other.

Establishing industrial areas downwind can reduce the impact of pollution on people to a certain extent.

In fact, compared with later generations, the "industrial zone" that the Qingque tribe is going to build is really simple and pitiful, and its scale is also pitifully small, so the corresponding pollution it can bring is extremely limited.

Even if they live in close proximity, there won't be much harm.

After Han Cheng expressed his thoughts, Heiwa thought for a while and nodded in admiration. The Son of God is the Son of God. He thought that he would be right if he followed the original plan. Now it seems that things are not what he thought...

After selecting a residence and deciding what to build first, on the third day after arriving in Tongshan, the people of the Qingque tribe began to get busy under Han Cheng's arrangement.

Heiwa and two others were working on the stove, while the rest were building the wall according to the lines drawn by Han Cheng.

In addition to the twenty citizens led by Junior Brother Sha and fifteen slaves, the people who came to the Tongshan residential area this time included ten people led by Han Cheng.

Han Cheng came here to take charge of the situation, Heiwa came here to make the bed, and the rest of the people were here to protect Han Cheng's personal safety.

It is very necessary for these eight people to protect Han Cheng's personal safety, because after getting on track here, Han Cheng and Heiwa will have to return to the tribe early.

It would definitely not be possible for only the two of them to travel together back to the tribe. Even if Han Cheng had such a big heart, other people in the tribe would not agree.

These eight people who came out, in addition to protecting Han Cheng's safety on the way back, can also be involved in the early development of the Tongshan residential area at this time.

By this calculation, including Han Cheng who did not work hard enough to cover the cost, the number of people who could participate in the construction of the wall reached forty-two people.

The forty-two people were all strong adults, so they built the wall very quickly.

Of course, the construction of the wall in the Tongshan residential area is fast, not only because there are many people involved in the construction and the scale is far smaller than the large wall being built by the Qingque tribe, but also because the materials used are different.

At the foot of Tongshan Mountain, there are stones everywhere, and none of them are particularly large.

With ready-made building materials available, Han Cheng would certainly not ask people to dig and tamp the earth to build the wall.

If there are enough stones, building a wall with stones is much faster than rammed earth, at least twice as fast.

Because the stones only need to be piled up there, unlike an earth wall where after digging the earth, you have to tamp it down again and again for fear that it is not solid.

If you pile up a stone, it will take a while to tamp the earth to the same volume.

Moreover, compared to rammed earth, stone is stronger and can withstand wind and rain.

Many foreign civilizations in later generations were made of stone, and because they were strong and difficult to shake, many of them have been preserved.

In contrast, Han Cheng's motherland has a long history and has produced many exquisite, magnificent and fascinating buildings. However, because most of them have carved beams and painted rafters, many of them have been blown away by rain and wind.

The Afang Palace, which covered an area of ​​more than 300 li, was burned down by a Chu man, and ended up as a scorched earth. The Yuanmingyuan, like a pearl, encountered two robbers...

Another advantage of a stone wall is that no one dares to dig a hole in it. For example, cattle thieves in later generations would never choose to rob a house built of stone.

Because if you do that, there is a high possibility that you will be crushed to death.

Time passed by minute by minute, the sun set in the west, casting an orange glow, and the evening breeze blew, bringing coolness to the people who were moving stones and working hard to build another home for themselves.

"Try harder!"

Wearing leather gloves, Junior Brother Sha piled a stone weighing over 100 kilograms on the wall and supported it with small stones. He glanced at everyone and spoke loudly.

The most comfortable time to work is in the morning and at this time of the day, so of course you should do more work while it is cooler...
