Yao Ran left two teams of guards, and rushed back to Canglong City by boat early the next day. Pen "Fun" Pavilion www.biquge.info

Because Yao Ran began to issue various orders again, such as recalling Yao Bones who built an anti-wolf net wall in the grassland fortress, and recalling all the escort teams who were training and seconded outside.

Asked to transfer a batch of firewood knives, ten alpaca carts, armor, bows and arrows, iron spears, and other items from the direction of Yao Village, Yao Ran gave priority to directly picking up some stockpiled tools and weapons in the warehouse of Canglong City.

Twenty people were seconded to the local guards in the grassland fortress, and after the order was issued, it only took one day from the time the order was issued in Canglong City to the time everyone came back to restore their lives.

After the fifty people were assembled, led by Yao Shi, the captain of the guard, Yao Ran informed Yao Shi of a clear purpose, that is, to kill all the four-legged animals around the Great Lake tribe. The mission was bloody, but it just sounded.

That's not what I did when I was hunting. But this time it was not, it turned out that when I encountered a wolf's den, or the habitat of some large animals, if it was not a special situation, the hunters did not like to move those places.

But Yao Ran's order this time was to cut off the household, and within a radius of five kilometers from the grassland tribe, the first to draw a map, clear out the forest path, and mark the road.

Second, clean up all animals that threaten human life, including big bugs and the like. The rabbit that is in a hurry is also counted, as long as it can bite, it will not leave a live mouth.

The third is to deter the villagers of the grassland tribe, but you can't bully, you have to show your muscles, and you have to coexist peacefully, of course, hooking up with a little girl or something, it's not within the ban, it's also a kind of showing muscles.

The fourth is to set off on the same day to protect the personal safety of Yao Bones and other construction team members.

The order that Yao Gu received was even more complicated. After arriving at the other side, build a dock as soon as possible to facilitate the docking of the Gonggong.

Roads were then opened to facilitate the transport of supplies by alpaca carts. From the pier all the way to the steppe tribes. Strengthen the transportation capacity around the steppe tribes.

The third is to build a dock near the pier, including a harbor camp. Including residences, warehouses, aquatic terminals.

At the same time, the work was carried out to help the steppe tribes to build guardrails, fences, build brick kilns, and stock up on timber, but not to cut down rubber trees, only when the roads were planned, and if there were more than ten rubber trees, they needed to be transplanted.

The follow-up materials for the subsequent work, the personnel are allocated by Yao Bone at will, and Yao Bone is directly responsible for it, and Yao Ran doesn't even look at it.

After sending another drawing to Yao Huo and the others, he went back to his residence in Canglong City. What drawings did you draw again?

At noon the next day, the fishing boats were full of all the people and set off for the Great Lakes tribe. Yao Ran stayed in Canglong City first, continued to allocate supplies, and most importantly, a drawing in his hand, a simple ferryboat.

This is a kind of propeller made by Yao Ran using a simple one-way rotating impeller, as long as two people press the lever left and right, the impeller can rotate. It is also expected to be able to reach 200 revolutions per second if it idle.

Of course, it can reach about 10 revolutions in the water, and the hull is half the size of a fishing boat. But such a ferry boat is actually the prototype of an assault boat. Because the weight of this two-person steering gear is not light, Yao Ran also designed a matching hull.

In the end, Yao Ran, who had been holding back all night, finally completed the design, and the next morning began to study in the dock with a group of carpenters, taking materials, cutting, and then the general shape production began to be made within three days.

And Yao Huo and others also started the day after receiving Yao Ran's drawings, the mold production of the overall casting, and the grinding and production of the steel construction of the key components.

Although the productivity of the entire territory under Yao Ran's name is still in the era of craftsmen's workshops, it is definitely impossible to reach the standard of an industrial age without the inheritance of craftsmen and the combination of theoretical knowledge.

Unless Yao Ran can directly produce, or make CNC machinery and equipment, now even the simplest turning, milling, planing, and grinding are measured according to drawings and tools, and three workers produce the same part. In the end, the best can be barely made.

Yao Ran, who holds a retinal weapon, if there is no problem with the energy supply of the parts, Yao Ran can try to make a spaceship.

Of course, if you really want to build a spaceship. Maybe one of the materials is enough for several generations of R&D and manufacturing, even if it is supported by Yao Ran's data drawings, but when it comes to the actual production, it will be difficult. The simple truth is that no science is independent of its own system.

If we want to translate theory into practice, then what is needed is the progress of the entire scientific chain, not just the sudden progress of one item. If any one link drags on, then the whole project may be stalled.

And now after Yao Ran returned to the mountains with the expedition and the retinal system, it took less than a year to find iron ore, lime, and cotton, which is already a leap forward, and now rubber has been discovered, which is an important part of the Iron Age.

If the carbon content of molten iron can be reduced and the castings of steel components can be cast, then Yao Ran's current scientific and technological capabilities will be greatly improved, and Yao Ran is now using whether it is a method of frying steel or a forging method, one is that it is difficult to achieve low-carbon standards. Another is that it is difficult to recast. are not suitable for mass production.

If the population is really huge, it can be made in batches simply by hand, but the population is one of the problems that Yao Ran is facing now.

Sometimes Yao Ran often thinks, shouldn't I be able to be an uncle? Why didn't the uncle do it, every day he was either striking iron or burning coal, and now he is working as a boatman.

Finally, with a length of eight meters, a width of three meters, and a depth of two meters without sails, the first ferry boat was completed, and such a ferry boat can also be used as a fishing boat, but the catch is relatively small. Fortunately, such a small boat can be operated by three or two people.

But the ship has not yet been delivered, Yao Ran sighed, looking at the calm lake from the dock. "It would be nice to have a phone call, and then make a call and ask, why hasn't it been done yet? Isn't it all done! ”

Of course, Yao Ran is idle here, which does not mean that the shipbuilding work will stop, but with the first prototype ship, the follow-up ships will be built by others Yao Ran will come to the stage acceptance inspection.

Lazy people create the world, Yao Ran is such a lazy person, I'll just accept and check that you guys. So now Yao Ran has time to lament and sigh here.

In the afternoon, a huge convoy finally drove into Canglong City. So far, it has only taken seven days from the news to the completion of production. (To be continued.) )
