Although Han Wenzheng does not have a complete design of this kind of flyship in his brain, it is not difficult for him, he is no stranger to ships, and he has seen countless ships, so the design is not difficult, at most it is to design while doing it, and if it is not done well, it will be done again. According to the characteristics of the Nianxiang River - the river is wide and deep, even a 3,000-ton ship can sail, so he designed and built a cargo ship named Flywheel No. 1 with a displacement of 2,000 tons, of which, the ship weighs 1,000 tons and can transport 1,000 tons of goods, which is a very large ship.

Shipbuilding is not an easy task, especially a two-thousand-ton ship, fortunately, Han Wenzheng's carpenter is experienced, and he is no stranger to the work of a carpenter, coupled with his own infinite strength, even parts weighing dozens of tons can be easily moved, so that the manufacturing is not so slow.

Shipbuilding, of course, can't use ordinary wood, if you want to use all the best wood, fortunately, there are countless trees on this planet, and some are high-quality wood, otherwise, Han Wenzheng will have a headache for a longer time, but now there is no such problem, but it took him a long time to log.

Wooden nails can no longer be used for shipbuilding, iron nails must be used, it is not difficult, and there is iron, just hit. The adhesion between the parts is not enough, it is not difficult, use lime as a binder, lime, no, it is not difficult, dig limestone to burn. In the process of shipbuilding, Han Wenzheng overcame all kinds of difficulties and took more than a year to build Flywheel No. 1.

In this year, Han Wenzheng also made a lot of wooden boxes, and a large number of wooden boxes were needed to load coal when digging coal, but it didn't take much time to make a wooden box, and it only took a few minutes for Han Wenzheng to make one.

Han Wenzheng stood on the shore, looking at the huge body of the flywheel No. 1, and a little bit did not believe that he could actually build such a large ship, although it took more than a year to build, but he thought it was still worth it, the tools still had to be made the same, with this ship, it will be easy to do anything in the future, if you want to do it, you must first sharpen its tools, the teachings of the ancients are very correct, he Han Wenzheng is fed up with the days when there is nothing.

The coal on the shore has already piled up, and for more than a year, the one hundred and fifty agencies have been constantly transporting coal, and the result is so much, now, there are tens of thousands of tons, and after these coals are transported back, it is almost possible to make the first clansmen.

After carefully inspecting the ship again, confirming that there were no problems, and preparing all the supplies, Han Wenzheng ordered: "Load." The organisers brought boxes of coal from the shore onto the ship, and stacked them neatly, and soon 4,000 boxes of coal were loaded.

Finally set sail, Han Wenzheng still carefully inspected the ship, and then ordered to sail. He sat in the wheelhouse, activated the mechanism, all the mechanism at the bottom of the ship started at once, three on each side of the six flywheels, on the pedal at the bottom of the cabin, there were sixty people on the same step, the six flywheels rotated together, the flywheel turned very fast, and the speed of the ship was also fast. Han Wen was turning the rudder of the ship and driving the Flywheel No. 1 downstream. After half an hour, Han Wenzheng felt very satisfied with the flywheel No. 1 that he had exhausted and built with all his might, needless to say, the wood of the hull was eight inches thick, and there was nothing to say if it was not strong. Steering and so on can be done in the wheelhouse, no need to go out of the wheelhouse at all, he has a time and space illusion, he is not driving a primitive wooden ship, but driving a modern warship, the ancient mechanism is really unpredictable. When it comes to speed, it is super-first-class, and the machine people will never get tired, the flywheel they step on gives the flywheel No. 1 a strong power, the speed of still water can reach 40 kilometers, which is already very fast, and now it is down the river, almost able to reach a speed of 50 kilometers, this speed is really fast enough, but it is really presented in front of Han Wenzheng.

The straight-line distance from the coal mine to Yanhuangcheng is 770 kilometers, and down the river, the river bends, almost a thousand kilometers away, even with the adjustment of the flywheel No. 1, it will take 20 hours to return to Yanhuangcheng, which of course has to be done without any obstacles on the way.

The night is deep, although Han Wenzheng has a pair of sharp eyes, he can see things in the dark like day, but he does not dare to let go of the speed of the flywheel No. 1, in case of any special event, the flywheel No. 1 has an accident, even if he wants to cry, he can't cry, stop the No. 1 and No. 2 flywheels, leaving only four flywheels to operate, so that the whole ship travels at a speed of thirty kilometers per hour, after all, safety first.

The journey was finally smooth sailing, and it took thirty hours to arrive at Yanhuang City safely, considering that this was the first voyage and the unfamiliarity with the waterway, this time was still acceptable, and in the future, it was familiar with the waterway, and this time could be shortened.

The agency people in Yanhuang City began to unload, moved the boxes to the river, then moved them from the river to the energy pool, and then poured coal into the "cannibalistic" mouth of the energy pool, and then sent the empty wooden boxes back to the ship, and there was still a 7,000-meter distance from the shore to the energy pool, and it took six hours for the 300 agency personnel to complete the unloading task.

During these six hours, Han Wenzheng was inspecting the ship to see the degree of wear and tear, to see if there was any damage, and now, the flywheel number one was his biggest possession, and he had to be careful. Then add some pine oil extracted from the resin of the oil pine tree to the bearing as a lubricant, and when everything is ready, drive the boat, go up the river, and return to the coal mine.

Going upstream, the speed is naturally not as fast as going downstream, but when going downstream, it is fully loaded, and upstreaming is unloaded, and the speed is basically the same as the speed when still water, and it took 35 hours to return to the coal mine. In this way, it took a total of 71 hours, that is, three days can be a round trip, and a thousand tons of coal can be transported in one round-trip, which is not a small amount.

Now the energy in Yanhuang City is only two crystals, and there are still eight crystals, so it still needs 160,000 tons of coal to be able to produce the first clan, and in the case of sufficient coal supply, it can be transported one hundred and twenty times a year, of course, this is the ideal value, deducting bad weather such as rain and windy weather, it is good to be able to transport one hundred and ten times. That is, it can transport about 100,000 tons of coal every year, which means that it only takes more than a year or two to be enough, compared to just logging, it is much faster, and it does not damage the environment much.

For the next year or so, Han Wen was concentrating on transporting coal, and everything else was put aside, of course, occasionally two shovels and hoes, and some boxes were made, and a few people were also made, which was a trivial matter that could be ignored.

For more than a year, it has basically been smooth sailing, there is no hindrance, but it is not entirely smooth sailing, for example, there was a battle with a huge python, that time it was night, I don't know what the python in the road was faint, and actually came to attack the boat, this damn python is very big, the body has the thickness of a bucket, up to more than ten zhang, however, since it dares to attack the ship, Han Wenzheng will naturally not be polite to it, and the gun is broken and picked it, and the fat snake meat is cut to make a delicious snake soup, Han Wenzheng still feels that the aftertaste is endless, I haven't eaten such a delicacy for a long time。

There have also been crocodile attacks, but under Han Wenzheng's moon-chasing bow and sharp gold arrows, they can only be sent to death. At other times, nothing happened, it was very smooth, there were few people here, and there could be no robbers or anything like that, and peace was inevitable.

Yanhuang City was attacked once, and that was last year, when the wolves attacked. I don't know what the problem is in the road, there are wolves who come to attack Yanhuang City, and 10,000 evil wolves attack Yanhuang City under the command of the wolf king, but, alas, the consequences are too miserable, these wild wolves with an average strength of not even one level go to attack a city with a ten-level defensive formation, what is it that is not looking for death?

Under the command of Qiushui, the system started the defensive counterattack mode, don't think that the defensive formation can only be defense, and there is also a certain attack ability, but the strongest attack is only about level seven, but, even if it is only a seven-level attack power, dealing with these evil wolves whose strength is less than a level is already a super knife to kill chickens, as a result, only dozens of ten thousand evil wolves escaped, and these dead evil wolves have become two hundred tons of meat resources stored in the unlimited capacity warehouse of Yanhuang City, which is also a little gain, at least, Han Wenzheng will not have to worry about no meat to eat in ten years。

Although, Yanhuangcheng is now the only one in Han Wenzheng, and the demand for food is extremely low, and it can even be said that there is no demand at all, after all, a person is not hungry when the whole city is full, there are fish in the river, and wild animals in the hilly areas on the shore, so to speak, food is not a problem, if Han Wenzheng is hungry, he can hit the prey with his hands. However, Han Wenzheng still used his rest time to open a few acres of wasteland in Yanhuang City and plant some wild vegetables and rice. Isn't it? If you have a lot of harvest, you can store it, and it will still be useful in the future, and you can use it as a seed even if you don't eat it.

Standing at the door of the City Lord's Mansion, looking at the numbers displayed on the display board on the left side of the City Lord's Mansion. Population: 0 (Hangul is not counted in the urban population). Energy (crystals): 10. Staple food (tons): 0.5. Meat (tons): 200. Vegetables (tons): 0.5. Fiber (tons): 0. Timber (t) 10. Stone (m³): 5. Medicinal herbs (tons): 0. Jade (tons): 0. Precious metals (tons): 0. Base metals (tons): 1.

His heart suddenly gave birth to an infinite feeling, since coming to this planet that he named the new earth, to today, almost six years, finally, relying on his own hands to make enough energy to create the first compatriot, his lonely days will be in the past, from today on, he also has a companion, there is a compatriot who can speak, can help himself, the future, is beautiful.

(Finally one more person, guess what, who will appear first?)
