"Roar—"

When the thick black iron chains reached the shore safely and smoothly, everyone in the river and on both sides of the river involuntarily let out loud shouts to vent the pride and excitement in their hearts.

And they succeeded!

With such a thick and heavy black iron chain, even the most powerful warrior in the Fire Tribe could not transport one end of it smoothly to the other side of the river.

When Su Ming proposed this method of transportation and installation, everyone was still very worried, for fear that the black iron chains would directly sink those ships, after all, the black iron chains were so heavy, and when they were coiled together, they were even bigger than the size of the ships.

This couldn't help but worry them, but with their trust in Su Ming, they also made an attempt with trepidation.

Now, they have completed the transportation of a black iron chain, which proves from the side that the method proposed by Su Ming is feasible, safe, and can be used.

And this cannot but say that this is a feat, this chain has been safely transported by them, then there is a second, a third...... Until all chains have been transported.

When all the black iron chains have been completely transported, then the most important part of their construction of the bridge has been completed, how can this not make them excited and excited.

Seeing the excitement of these soldiers, Su Ming and Hei Er were also infected by it, and they couldn't help but be happy, and even joined in with it, letting out bursts of huge and heavy shouts, they were also venting their excitement and pride from the bottom of their hearts, although for such a result, it was all expected by Su Ming.

When the warriors had almost vented their excitement, they began to prepare to fix the black iron chains.

When those black iron chains were created, Su Ming specifically asked them to be much longer than the width of the mountain gap, in order to facilitate the current safety operation.

I saw that the big iron hook at one end of the black iron chain was directly carried by the warriors of the Fire Tribe and buckled to a already made iron ring, and fixed it well.

Then the other end of the black iron chain was tightly fastened to a strong black iron ring in the same way. In this way, the ends of the chain are fixed on either side of the gap in the mountain.

And after the installation of the first black iron chain, those warriors of the Fire Tribe, without stopping, transported the second black iron chain in the same way.

After transporting it, it was followed by the same method, fastening it to the gap in the mountain, on the black iron ring that had been laid out, so that the two chains were side by side.

As the days passed, and after several days of continuous operation, the fifteen black iron chains used to build the bridge were all transported across the river and fixed to the gap in the mountains.

Next, there is another process that is not only a heavy task, but also becomes dangerous and boring, and that is to raise the height of those black iron chains, you know, the current black iron chains are only less than a meter above the top of the river.

It is also the location of the dry season of the great river.

Not to mention, the distance from the water surface is so close, there is no attack distance from the wild beasts in the water, let's just say that when spring comes, the snow melts, and a large amount of snow water flows into the big river, and the raised water surface can directly submerge all the black iron chains, and there is a huge safety hazard.

The lifting of the black iron chain is also very simple, even in the era when there is no construction machinery, it can be successfully completed.

The warriors of the Fire Tribe were divided into five groups equally, and the average group of warriors was responsible for the lifting of the three black iron chains, and then continued to lay thicker planks on both sides of the three chains according to the method of paving the pontoon road.

Because at the beginning of the construction of the bridge, Su Ming formulated such a construction method, so that the middle of the three black iron chains was higher than the other two, so after the completion of the laying, the two black iron chains suddenly became a wooden iron chain bridge.

The chain in the middle was slightly suspended on the wooden planks of the bridge deck.

Then, the soldiers carefully installed the three frames that had been made on the bridge deck at intervals.

On each tripod, there are two smaller chains, two forks at one end and two stout iron hooks at the forked ends.

At the top of the chain and the tripod, there are also some rough pulleys, and those black iron chains pass through those pulleys to become a simple and practical engineering tool, commonly known as a gourd.

Under the operation of the Fire Tribe warriors, one end of the chains on those gourds steadily hooked the huge black iron chains, and then those warriors pulled the other end of the chains, and as the warriors continued to pull repeatedly, you could see that the black iron chains of the bridge were driven by the gourd chains, slowly rising upwards.

Under the hard work of the soldiers, the black iron chain in the middle was slowly raised to the end of the tripod, and it had been raised to more than one person, and Su Ming estimated that it was almost two meters.

The height had reached the highest point that could be raised now, and then the raised chain was firmly fixed to the black iron ring that had been made long ago.

In this way, the chain of the first bridge was lifted, and the next step was to directly fix the hoist on the tripod to the black iron chain that had been lifted, and then hook one end of the lifting to the remaining two chains.

Then, with his own strong strength, he began to pull the gourd, lifting the hooked black iron chains, so that the remaining two black iron chains, along with the laid wooden boards, slowly continued upward.

Then it was fastened to the black iron ring that had been prepared for a long time. Then attach the hoist to the tripod again and use it to lift the black iron chain in the middle.

In this way, each group in charge of the Fire Tribe warriors is constantly raising the black iron chains upwards at a rapid pace.

Every day is the same work, constantly improving and fixing, improving and fixing, and the cycle repeats. Eventually, those black iron chains will reach the height of their design, be fixed, and be out of range of the attack of the savage beasts in the water.

It has become a real black iron chain bridge, connecting the two banks of the river, breaking the tradition of waiting for the season to cross the river, facilitating the flow of people and materials on both sides, and strengthening the communication between the tribesmen on both sides.

And it also increases the voice of the Fire Tribe in the alliance of the three clans, after all, with this chain bridge, the Fire Tribe can deploy personnel on a large scale anytime and anywhere to and from both sides of the river.

Originally, the author Jun was playing mahjong, and he won more than 3,000 after a while. But it suddenly occurred to me that there was no update tonight, so I pushed off the game and went home to code words. But just after thinking about it, I coded for a month, and the manuscript fee was up to one month's water and electricity bills, and the gas bill had to be paid again. Why do you keep changing today and continue to play mahjong, maybe the water and electricity have been settled this year...... In the midst of remorse............
