The power of technology is really amazing after it explodes.

Although the technology of the Ming Dynasty is not very developed at this moment, it is quite terrifying when applied to building bridges and roads.

It is quite difficult to walk twenty miles a day in the tropical rainforest, but it seems quite simple to work together with hundreds of trees and wood cutting machines.

Taichang held up a telescope and looked at the falling trees in the distance. He couldn't help but sigh that if people were to cut them, they would probably not have the ability to cut through these two or three thousand miles wide tropical rainforests even after cutting them for a few years.

It’s different now. Using a machine to chop it is really like cutting melons and vegetables.

South America seems to have many unique features in the application of technology in tree cutting and wood cutting.

They even installed large rollers like maces under the large machinery. The guy flew over and the wooden stakes left after cutting down the big tree were gnawed to the same level as the ground.

No wonder he didn't see anyone digging the roots of a tree this time. With this thing, the roots of a tree can be leveled without digging them out.

Taichang looked at it for a while, then couldn't help asking: "Bogong, what if you plant saplings after cutting off the big tree, do you have any way to quickly dig out the roots of the big tree?"

Du Linzheng nodded without hesitation and said, "Yes, Master, if you want to plant saplings, we will match rollers of the corresponding width according to the size of the stump.

That type of roller is pushed by a steam piston and can be gnawed directly to the ground. No matter how big the roots of the tree are, the roller will be gnawed hard and will be gnawed quickly.

Well, I thought of it.

Taichang nodded slightly, then put down his telescope and looked at the Amazon Tribal Alliance soldiers who were preparing to water the road nearby.

At this moment, a foot thick wooden square was used to form a rectangular frame that could not be seen at all. A foot tall wooden board was fixed every ten feet in the middle of the frame, and in the middle of the wooden board were small squares tied with steel bars.

With such a structure, the chariots and carriages will definitely not be damaged.

But he was a little curious about what would happen if the tree-cutting machine pressed on it.

You should know that the machine for cutting trees is not easy. The docks must be covered with thick steel plates, otherwise they will be crushed.

He couldn't help asking, "Can this road surface withstand the crushing of large machines?"

Du Linzheng shook his head repeatedly and said, "This may not work. It has to withstand the crushing of large machines. At least two feet thick reinforced concrete must be poured on the road surface."

Taichang couldn't help but say, "Then how can these machines be transported back after they are driven?"

Du Linzheng said without hesitation: "There are many ways. We can build another dock on the beach, drive the boat directly, or cut off a piece of trees on both sides of the road and drive it back directly.

Or, we can find a larger tributary and directly drive the road.

In short, there are many ways to transport these machines back. Master, you don’t have to worry.”

Well, he really doesn't have to worry about these things.

Taichang nodded slightly, then waved his hand and said, "Let's go back and see how the bridge is being repaired."

Originally, this bridge was easy to build. If you just pass by people and cars, it would be repaired in about a month.

However, Taichang also wanted to drive over under the bridge by armed merchant ships and flying dragon warships, so it was a bit difficult to build the bridge.

If the armed merchant ships and the flying dragon warship can drive over, the bridge deck must be at least three meters above the water surface.

Moreover, Du Linzheng also planned to use the suspension bridge structure to cross the river channel about a width of about a hundred feet on both sides, and the piers would be built higher.

At this moment, a row of three-meter-high bridge piers in the middle have already dug the foundation, tied steel bars, and prepared to pour concrete in it, but the foundation is still dug on both sides.

Taichang looked at the big pit with a depth of more than three meters and couldn't help but feel embarrassed: "Is my requirement too high? If the bridge only needs to be built to reach one meter high, will the piers be poured now?"

It is indeed quite troublesome to dig a hole in this river, because it will seep water if it is less than ten feet deep after digging. If you don’t use a water truck to pump it up, it will become a big hole and you can’t dig it at all.

Du Linzheng quickly shook his head and said, "This is actually nothing. Cultivating a bridge of about 100 feet high is no longer a challenge for the soldiers of the Amazon Tribal Alliance. This time, they just let them exercise and cultivate a higher one."

Uh, you guy is really good at talking.

OK, it's fine.

Taichang couldn't help but run under the flagship every day, checking the progress of road construction, checking the progress of bridge construction, checking the food of the soldiers, and then trying the herbal tea that they had cooked.

Running back and forth day by day, life is passing quickly.

The construction speed of the China-Africa channel is also amazingly fast.

Twenty days later, the passages on both sides were built for more than 500 miles, and the first relay station for the hot air balloon was also repaired.

Unexpectedly, good news came after the hot air balloon had just flew over for a day.

That afternoon, Taichang and Du Linzheng were inspecting the construction progress of the bridge. Aluka suddenly rushed over and said excitedly: "Master, we have seen the camp of the Black God Army."

ah!

What's going on?

Did they accidentally choose the place closest to the Black God Army Camp to repair the road?

When Taichang heard this, he couldn't help but be surprised and said, "How far is the Black God Army Camp? Have you built the road out of the jungle?"

Aruka quickly explained: "No, Master, we have not built the road out of the jungle yet. The Black God Army camp was discovered by hot air balloons.

According to the hot air balloon's voyage, the Black God Army's camp should be less than a thousand miles away from here, and our avenue is about four hundred miles away from the edge of the jungle."

It turned out that it was discovered by the hot air balloon.

This is rare good news. After all, as long as it is connected to the Black God Army's camp, he can understand the specific situation of the Black God Army.

It was more troublesome to contact the outside world after they entered the tropical jungle. Especially the camp of the Black God Army was not on the coast, and he had not received any news about the Black God Army for a long time.

Now that they were all going to build the road near the Black God Army's camp.

Taichang thought for a while, then ordered decisively: "Go back quickly and ask your soldiers to speed up the progress as much as possible, so as to only build the road out of the jungle in half a month.

Then you send someone to search. After finding Zhang Hengchuan and Lin Chaojie, you can quickly bring them over to report the specific situation of the Black God Army."

Aruka hurriedly bowed and said, "I will understand."

After saying that, he turned over and ran backwards.

Du Linzheng looked at his back and frowned slightly and said, "It's less than a thousand miles north, but there are at least one thousand miles south, or even two thousand miles south.

At that time, it will be more troublesome to transport steel bars, cement, sand, gravel and wood. After all, the carriage can run a hundred miles a day, and it will take half a month to run a thousand five hundred miles a day. It will take a month to get back and forth!

Your Majesty, why don’t we build more carriages?

Otherwise, the supply of materials may not be urgent at that time.”

Taichang shook his head slightly and said, "No need for this. The Black God Army has at least 100,000 wooden chariots. That kind of chariot is easier to use than a flatbed chariot. Not only does it contain more things, it is not afraid of rain.

Just ask them to help transfer the fortunes at that time.

The key now is to quickly repair the bridge. As long as the Black God Army's chariot can pass, it will definitely be no problem to transport materials."

Half a month later, Aruka really built the avenue out of the jungle.

However, when he ran out of the jungle with his personal guards, he was stunned for a moment.

Because all the people who appeared in front of him were dark people, he didn't know how to communicate with others.

He was stunned for a while before he tentatively said: "Anyone of you can speak the Ming Dynasty's official language?"

Are you talking nonsense?

Zhang Hengchuan immediately rushed forward and said, "You are soldiers of the Amazon Tribal Alliance, are you?"

Hey, this person seems to be from the Ming Dynasty.

Aruka deals with Ming officials every day, and he can recognize him even if he slanders his face.

Just now, he was stunned by this dark man and didn't look carefully.

He naturally saw this.

He nodded repeatedly and said, "Yes, yes, I am Aruka, the chief of the Amazon Tribal Alliance.

Do you know where General Zhang Hengchuan and General Zhang and General Lin Chaojie are?"

Zhang Hengchuan said without hesitation: "I am Zhang Hengchuan, and the one behind is Lin Chaojie, what's wrong?"

Oh, this is so good.

Aruka quickly explained: "That's right. Half a month ago, the emperor issued an order to ask me to find you, and then I will take you to meet the saint."

You didn't say it earlier!

Zhang Hengchuan asked quickly: "How far is this place from where the Holy Divine is?"

Aruka said without hesitation: "It's about a thousand miles."

Upon hearing this, Zhang Hengchuan immediately turned around and said, "Chaojie, hurry up, order one of his personal guards to prepare three transfer horses."

Now there are hundreds of thousands of war horses here, and preparing hundreds of war horses is naturally very simple.

After a while, hundreds of personal guards came with four or five hundred war horses.

Zhang Hengchuan didn't say much, so he took Lin Chaojie and a group of personal guards to set off with Aruka.

They didn't have time to sigh at the spaciousness of the forest avenue along the way, just kept covering their heads and running forward. The next afternoon, they arrived at the bridgehead of the Congo River Bridge.

Taechang didn't expect that these two people would come here so soon.

After the monarch and ministers greeted him for a while, he couldn't help asking: "Hengchuan, how about it? Are Atlanti's men gathered?"

Zhang Hengchuan hurriedly bowed and said, "Master, the two million new recruits from the Kingdom of East Africa have already gathered on the grassland in the north, and they are stepping up their training now."
