This kind of plant that uses breath to grow can only survive for a few months. The vines are very tender when they sprout. After being cut off, they can be peeled off into thin strands, which is considered an extremely precious material. Even on the World Island, only a few people can afford such clothing.
When the vines grow up, they will become much thicker and tougher. Not only is it difficult to process, the color will also become dull. Elves usually use it to repair houses and make armor, but the most indispensable thing on the world island is all kinds of high-quality wood, so the aging golden vine is only included in the manual as a substitute for another fast-growing vine. in.
However, when the first batch of samples were delivered to Golden Spike City, Xia Fan quickly noticed that it was extremely tough and had high strength, making it suitable for use as a cushion. Especially under the control of elves, it also has a certain degree of clinging and can wrap itself around solid objects.
This idea was immediately applied to the machine beast.
Facts have proved that the combination of the two has an excellent effect. It is no longer a rigidly connected skeleton, and its impact force is immediately reduced by most of it. The vines wrapped around the outside are like muscles clinging to the bones. Each contraction absorbs a large amount of kinetic energy and loses pressure. It will be released from time to time, which in disguise improves the flexibility of the machine beast.
Compared with the prototype that can only move at low speeds, the movement performance of this new product has been greatly improved.
Of course, this is not the only practical benefit obtained by adding cushioning joints. For example, wood wear and the durability of the telescope are all improved due to the slowing down of impacts. It's just that compared to the flexibility visible to the naked eye, these advantages are not so eye-catching.
Xia Fan had always been troubled by the fragility of wood. The most straightforward solution was undoubtedly to replace wood with metal. But just relying on a blacksmith's hammer to hammer out a reliable skeleton would definitely be a job that would take years, not to mention the mass production demand later.
Now, he has the idea of simply using wood to make the main components. Putting aside the fact that it is easy to damage, wood has many advantages - it is easy to process, has many sources of materials, is lightweight, and can be repaired wherever it breaks down. I really want to give up the telescope. Yes, it doesn't hurt to throw away the wooden frame.
"What about the price?" Ning Wanjun asked, "I remember that the exchange price for golden vines is not low."
"It's not low, it should be said to be very expensive." Xia Fan smiled, "But the main reason for the high price is that the quantity is small. The seeds produced by tree spirits are limited, and they will not be able to produce this kind of luxury in large quantities during their escape. It is a product of high quality. In addition, there are very few new shoots of golden silk vines, so the elves naturally will not reserve too much."
"So it's more cost-effective to exchange seeds here?"
"Or ask them to increase the catalytic capacity of the golden vine, but don't pick the new buds. According to Ai Li, this thing can grow quite well."
"Having said so much, it's time for me to give it a try, right?" Ning Wanjun rubbed her hands and climbed towards the machine beast.
"Your Highness has never manipulated this thing, is it okay?" Qiuyue asked worriedly.
"It shouldn't be a problem, right?" Xia Fan thought for a moment, "As long as she doesn't use too much force—"
Click!
Before he finished speaking, the machine beast sat on the ground with its legs raised and doing splits.
"your Highness-"
"Wanjun, are you okay?"
In the blink of an eye, Qiuyue and Mo Yun rushed over together.
Xia Fan couldn't help but cover his eyes. This is the disadvantage of using a heavenly motion instrument as a joint. There is no locking mechanism at the joint? As long as the operator doesn't control it, it can make more than one turn.
Except for the golden vine? There are two other types of seed products that Xia Fan is also very fond of.
One type is rhizobia? It anchors the sea sand to the tangled base of the tree boat until a soft patch of land is formed. It is also the basis for the formation of the World Island. Can it be said that there is no rhizobia? There would be no place for the islanders to survive today. So even if it doesn't produce results, it can't be used for sewing or processing? Will the elves still convert part of the seeds into rhizobia? To ensure that the roots underneath the tree boat can withstand the impact of waves.
Xia Fan doesn't have any original ideas about this? They are grown from the same crops as crops. Rhizobium plants are generally mutations caused by symbiosis with rhizobia bacteria. In addition to improving soil quality, their biggest role is to fix nitrogen. And until the chemical synthesis of ammonia was invented, all nitrogen came from natural cycles? This leaves most land with a nurturing limit. Can it be said that it is a breakthrough in ammonia synthesis? Only then did modern fertilizers come into being, and with chemical fertilizers, humans were able to break through the limitations of nature and feed most people with crops from a small amount of land.
In an era when separation of elements is difficult? It is obviously more difficult to develop chemical fertilizers than to reach the sky, so using rhizome plants to provide nitrogen sources is undoubtedly a tricky method. certainly? If it were just an ordinary nodule plant, the nitrogen output would be so minimal that it is basically impossible to count on it. As a product of tree spirits, rhizobia's potential is obviously much greater than those of ordinary crops - at least he has never seen any grass that can transform sea sand into soil bit by bit, and on this basis, give birth to a vibrant tree boat.
Of course, the specific effect of rhizobia fattening can only be determined by comparing the experimental fields, which can take at least a year. But even if the effect is not obvious, it can still be used to green the beach and prevent the alkalinization of the land around the salt fields. It can be said that as long as you buy it, you will not lose money.
The other type is the soft bamboo nan at the front of the manual, which Xia Fan originally thought was the "rainwater collection grass".
This plant looks like a shrimp cage, lying on the ground one after another, and can extend hundreds of feet; it can be as thin as a bamboo pole and as thick as a bucket. According to the elf, it has a very wide range of uses on the world island. It can not only collect rainwater and send the water to the residents living in the canopy through internal peristalsis, but also pump seawater to help the islanders put out fires. In a nutshell, it can be called a biological pipeline, shouldering the important task of water distribution on the World Island.
The mere fact that it can pump and drain water is attractive enough. Whether it is salt fields to divert tides or farmland irrigation, it has its own stage to shine.
But what really attracted Xia Fan was not this.
When it comes to pumping water, both water trucks and overturning trucks can do it, but at best they are inefficient and require people to step on them, and Jinxia City is far from being short of manpower.
What he likes is the ability of Ruanzhunan to propel itself by water jet.
If this thing was allowed to grow at the bottom of the cabin and continuously spray water outwards, wouldn't it become an axial flow pump? If one is not enough, you can have a row. As long as more water is sprayed out, the greater thrust the ship will get.
Compared with the green shuttle that also paddles by itself, the swing efficiency of the tentacles is undoubtedly much lower than that of water spray, and it is not naturally suitable for high-speed navigation. Once the speed increases, the irregular swing of light itself will bring huge resistance, but water jet propulsion does not have this concern at all.
The weak surface power has always been a major hidden danger for Jinxia City. Dongshengguo can bring one sailing battleship, but there is no guarantee that there will be two or three next time, let alone the West Pole Fleet that destroyed the World Island,
He doesn't want to let go of anything that can be used as a source of power - whether it is natural or man-made.
