At the construction site of Xinma City, the jungle has been cleared north for several miles, and the mountains of wood on the ground are already lined up like mountains.

Taichang held up the telescope and glanced at it, then discussed with Wang Chong, Su Feng and others for a while, but decided to build a row of city walls first and then build a row of hanging wooden buildings behind the city wall to try it.

This city wall must be built because there are no artillery that can destroy the city wall at this time. The city wall is still a natural turret and bunker, which still has a great effect on defense.

Moreover, there are no infantry fighting vehicles in the continental countries at this moment. It is almost impossible for them to destroy the city walls made of cement and steel.

As for why we should first build a row of hanging wooden buildings behind the city wall, it is mainly because the height of the hanging wooden buildings in his plan is one zhang, and the height of the city wall is also one zhang. In other words, the top of the city wall is basically flush with the platform of the wooden building.

In this way, by directly putting a springboard on the platform of the wooden building, the soldiers guarding the city could quickly run to the city wall.

This is a brand new way to defend the city, and he really wants to see the effect.

Moreover, the hanging wooden building is equivalent to a new building model. He doesn’t know how effective it is if he doesn’t build it first.

This kind of wooden building is not a pure wooden stilt building, but is supported by steel and concrete columns. There must have been no such house in the past, and there seems to be no such house in later generations.

To be honest, he didn't know what the effect of building it, so he wanted to repair a row first to see.

At this moment, the Indian tribe civilians in the entire Xinma City area have migrated, and the young and strong Indian tribes in North America are fine for the time being, so they are just allowed to build the city walls and houses.

The 90,000 young and strong people from the North American Indian tribe, plus nearly 10,000 civilians from the tribe, and the Jinyiwei and Shenwu Camp generals who helped to command were roughly 100,000 people. It was still easy to build such a little thing.

This section of the city wall is actually less than ten miles, because both sides are tributaries of the Amazon River, and the city wall cannot cross it.

Although the port terminal is more than twenty miles wide, the tributaries on both sides shrink in the middle at the entrance, so it becomes narrower less than three miles behind the terminal, so it is still very simple to build this section of the city wall.

However, there is another problem. More than ten tributaries are equivalent to cutting off the city walls on the south side of Xinma City into more than ten. Moreover, these tributaries have penetrated deep into the city. The entrances of the tributaries must be defended, otherwise the city wall will be built in vain.

This problem is not solved yet, so I can only wait until this section of the city wall is built before checking it out.

Taichang, Wang Chong, Su Feng and others discussed the location of the city wall and the style of the foundation, and 100,000 people started digging the foundation together.

Unexpectedly, as soon as I excavated, I encountered another problem.

The ground is full of tree stumps left after the trunks are sawed off!

Moreover, the stumps are densely packed with tree roots. In some places, the roots are like spider webs, which are scary.

The roots of this tree are fresh, not the kind that has been buried for a long time and rotten, and ordinary hoes cannot be dug.

This may be one of the reasons why no one has developed the original jungle of South America. It is too difficult to dig out the foundation in such a place.

However, this does not seem to be a big problem for the Ming Dynasty.

Because there are many people in the Ming Dynasty and are not afraid of difficulties.

Taichang looked at the dense tree roots underground, then looked at the dull hoe, thought about it again, and then said decisively: "Try it with a black iron knife."

Upon hearing this, Su Feng waved his hand quickly. Several young and strong men from the North American Indian tribe immediately pulled out the black iron sword and slashed at the roots of the tree underground.

The effect is pretty good. At least, the tree roots that are less than the thicker than the wrist will be cut off with one knife. However, no matter how large the tree roots are, it is a bit difficult to cut the black iron knife, especially some tree roots that are thicker than the arms, and the black iron knife is a little unable to cut.

After all, this thing is underground, and the black iron knife is equivalent to chopping together with soil, which is equivalent to increasing the area of ​​chopping.

Taichang thought about it again, then gritted his teeth and said, "Try taking the axe."

He didn't believe that a bunch of tree roots could stop them.

Soon, a Jinyiwei took out the axe.

Taichang waved his hand and then swung his axe directly to the tree root that was thicker than his arm and went down a few axes.

Fortunately, it was not difficult to cut the axe, and it was cut off in a few strokes.

That's all.

Taichang nodded slightly and said, "Split the person's hand, first cut off the tree roots with a black iron knife and an axe, then dig with a hoe, and take turns to go together."

Wang Chong, Su Feng and others quickly bowed and said, "I will understand."

Such a foundation is indeed a bit difficult to dig, but fortunately, they have 100,000 people.

These 100,000 people were scattered on a line less than ten miles away. Each meter was equivalent to about twenty people. No matter how many tree stumps and roots were there, it would not take too much time.

Moreover, the young and strong Indian tribes in North America were very familiar with digging foundations, firing bricks and tiles, and even watering columns. They were quite quick to do their work. In less than three days, the city walls and the foundations of the columns were dug.

However, at this time, they found another embarrassing problem, and there was no wooden squares and wooden boards used to water the columns!

There have been quite a lot of cement steel bars coming, because there are so many trees here that Taichang didn't think about pulling wooden boards or wooden squares from other places!

Moreover, there is not even a saw machine here now, no matter how many logs there are, they cannot automatically turn into wooden squares and wooden boards!

Taichang looked at the logs piled up like mountains, which were really embarrassing.

There are quite a lot of human tug-of-war here, but the Ming Dynasty has no need to tug-of-war with wooden squares and wooden boards for many years.

Because it is too difficult to use human tug-of-war to saw wooden squares and wooden boards, and it is very inefficient, which is a waste of time and manpower.

He frowned and pondered for a while on the construction site, and finally remembered that when the transit base was built on the southernmost part of the Xinyindu Islands, he pulled many saw machines over, and there were only more than 3,000 miles away from here, and it only took a few days to pull them over from there.

As for the 100,000 people, they don’t have to be idle these days, they can do their best to build the city wall.

Thinking of this, he said decisively: "Ziru, ask Yuanfang to send a ship to the southernmost transit base of the Xiyindu Islands and pull all the saw machines there. Wang Chong and Su Feng, you will bring all the people and build the city wall first."

With so many people working together, the construction speed of the city wall is still quite fast, and it is not a problem to have two feet tall in a day.

Six days passed, and the sawing machine on the Xinyindu Islands had just been pulled over, and the one-meter-high wall foundation had been almost completed.

After the sawing machine, sawing the wooden square and wooden boards became simple. The wooden square and wooden boards used for inverted columns were sawed out in less than two days.

When he was about to cast, Wang Chong came over again.

What else is there?

Taichang followed Wang Chong to the construction site and saw that the wooden frames about meter high had been erected, the steel bars inside had been tied, and the wooden tables about meter high were also built. Just carry the mixed concrete and go up and pour it into the wooden frame.

There seems to be no problem with this!

Taichang couldn't help but look at Wang Chong with confusion.

Wang Chong carefully pointed to the top of the wooden frame and said, "Master, if we water all the cement columns and then put the wooden square on it, the wooden square will not be fixed on the cement column. The wooden house on it is equivalent to being built on the cement column. The wind may blow away the wooden house on it!"

Uh, this one.

Fortunately, Wang Chong didn't take action recklessly, otherwise, once the cement was poured, it would be impossible to imagine.

Taichang touched his forehead awkwardly, then walked onto the wooden rack and looked at the steel bars in the wooden frame.

The steel bar is well-tied, and it is only necessary to put the wooden square card used to make the beam.

He looked carefully, then pointed to the top of the steel bar and said, "Piece here again, it's probably the height of the wooden square, and then put the wooden square on it and then cast the cement."

Wang Chong carefully reminded: "Your Majesty, we use one inch of wood square for cross beams. It's easy to say that if you put two pillars on it, if you put three or even four pillars on it, the cement that stirs the gravel on it will basically not be able to pour it down!"

This is simple.

Taichang said without hesitation: "You can pour the cement mixed with gravel to almost level with the newly tied steel bars on the top and then put the wooden square on it. In this way, there is only one little bit above, and it is no problem to use cement mortar directly."

All right.

Wang Chong hurriedly bowed and said, "I understand."

Taichang looked at the wooden frames around him, but sighed in his heart: "Oh, everything is difficult at the beginning, it is even more difficult without anyone helping me.

If there is an official from the Ministry of Works, these problems may not occur and he doesn't have to worry about them.
Chapter completed!
