Heavenly Dao Formula Chapter 189: Use of plants

This kind of breath-promoted plant can only survive for a few months. The vines are very tender when they sprout, and after being cut off, they can peel off strands of filaments, which are extremely precious materials. Even on the island of the world, only a few people can afford such clothes.

　　 When the vines grow up, they will become thicker and harder. It is difficult to process, and the color will become dull. The elves usually use it to repair houses and make armor, but the most indispensable thing on the world island is all kinds of good woods. Therefore, the aging golden vines in the manual are only listed as a substitute for another fast-growing vine. among them.

　　 However, when the first batch of samples were sent to Jinsui City, Xia Fan quickly noticed that it is extremely tough and has high strength, which makes it suitable for use as a cushion. Especially under the control of the elves, it also has a certain degree of clinginess, and can wrap around solid objects on its own.

The idea of ​​　　 was immediately applied to the mechanical beast.

　　 Facts have proved that the combination of the two is very effective. It is no longer a rigidly connected skeleton, and its impact is immediately reduced by more than half. The vines entangled are like muscles clinging to the bones, and each contraction will absorb a lot of kinetic energy. , It will be released when the pressure is lost, which in a disguised form increases the flexibility of the organ beast.

　　 Compared to a prototype that can only move at low speeds, the sports performance of this new product has been greatly improved.

　　 Of course, the actual benefits obtained by adding cushion joints are not the only one. For example, the wear of wood and the durability of the Tiandong instrument have been improved due to the reduction of impact. Compared to the flexibility that is visible to the naked eye, these advantages are not so noticeable.

　　 Xia Fan had been having trouble with the fragility of wood. The most straightforward solution is undoubtedly to replace wood with metal. But relying on a blacksmith's hammer to hammer out a reliable skeleton is definitely a work counted in the past few years, not to mention that there is a demand for mass production in the future.

　　 And now, he has the idea of ​​simply using wood to make the main parts. Putting aside the fragility, wood has too many advantages-it is easy to process, has many sources of materials, is light in weight, and it can be repaired wherever it fails. I really want to abandon the Tiandong instrument. It doesn't hurt to throw away the wooden skeleton.

　　"What about the price?" Ning Wanjun asked, "I remember that the exchange price of 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 the small quantity. The tree spirits produce limited seeds, so there will be a large number of them on the way to escape. It is similar to a product of luxury goods. In addition, there are very few new shoots of golden vines, so the elves will naturally not reserve too much."

　　"So it is more cost-effective to exchange seeds here?"

　　"Or let them increase the catalytic capacity of the golden stalk, but don't pick new shoots. According to Ai Li, this thing can grow."

　　 "I have said so much, should I have a try?" Ning Wanjun rubbed her hands and climbed towards the organ beast.

　　 "His Royal Highness has never manipulated this thing, can it work?" Qiuyue asked worriedly.

　　 "There should be no problem, right?" Xia Fan pondered, "As long as she doesn't work too hard--"

　　 Click!

　　 Before he could finish his words, the organ beast sat on the ground with his legs raised in the splits.

　　 "Your Royal Highness—"

　　 "Wan Jun, are you okay?"

　　 In a blink of an eye, Qiuyue and Mo Yun rushed over together.

　　 Xia Fan couldn't help covering his eyes. This is the shortcoming of using the Tiandong instrument for joints? 　There is no locking mechanism at the joints? 　 As long as the operator does not control it, it can turn a circle more.

　　In addition to the golden vines? 　There are two other types of seed products that Xia Fan likes.

　　 is nodular grass? 　 It can fix the sea sand on the bottom of the intertwined tree boat until it forms a soft ground. It is also the basis for the formation of the World Island. It can be said that without root nodule grass, there would be no place where the islanders live today. So even if it can’t bear fruit? 　 Can’t be used for sewing or processing? 　 Elves will still convert part of the seeds into rhizobia? 　 To ensure that the rhizomes under the boat can withstand the impact of the waves.

　　 Xia Fan didn't have any ingenious ideas about this, and he used it as the same kind of crops. Root nodule plants are generally caused by symbiosis with rhizobia, in addition to improving soil quality? 　 The biggest role is to fix nitrogen. And until the chemical synthesis of ammonia was invented? 　All nitrogen comes from natural circulation? 　 This makes most of the land there is a limit to nourishment. It can be said that it is the breakthrough of synthetic ammonia that makes modern fertilizer come out? 　With chemical fertilizer? 　Human beings are able to break the limits of nature? 　Using a small amount of crops to feed most people.

　　In an era when it is difficult to separate the elements? 　It is obviously more difficult to make chemical fertilizers than to climb to the sky? 　It is undoubtedly a trick to use root plants to provide a nitrogen source. Of course, if it is just an ordinary nodule plant, the nitrogen yield can be described as negligible, and it is basically impossible to count on. The root nodule grass, as a product of tree spirits, has much more potential than ordinary crops—at least he has never seen any kind of grass that can convert sea sand into mud a little bit, and on this basis give birth to vigorous tree boats. .

　　 Of course, the specific fattening effects of root nodule grasses can only be determined by comparing them with the experimental field, and it will take a year to say less. But even if the effect is not obvious, you can use it to green the beach and prevent the alkalization of the land around the salt pan. It can be said that as long as you buy it, you will not lose money.

　　The other type is the soft bamboo phoebe at the forefront of the manual, which is also what Xia Fan originally thought of as "rainwater collecting grass."

　　 This plant looks like a shrimp-catching cage, lying on the ground ring after ring, and can extend hundreds of feet away; it is as thin as a bamboo pole~IndoMTL.com~ and as thick as a bucket. According to the elves, it has a very wide range of uses on the world island. It can not only collect rainwater, send water to the residents living in the tree canopy by internal peristalsis, but also extract seawater to help the islanders extinguish fires. In a nutshell, it can be called a biological pipeline, taking on the important task of allocating water resources on the world's islands.

　　 just because it can pump and drain water, it has enough attractiveness. Whether it is salt pan tides or farmland irrigation, there is a shining stage for it.

　　 But this is not what Xia Fan is really attracted to.

　　 If you pump water, you can do it with waterwheels and rollovers. At most, it is less efficient and requires people to step on it. However, Jinxia City is far from the point of manpower shortage.

　　 What he fancyed was the ability of the soft bamboo pheasant to spray water.

　　 If you let this thing grow at the bottom of the cabin and spray water continuously, wouldn’t it become an axial flow pump? One is not enough to come in a row, as long as the more water is sprayed, the more thrust the ship gets.

　　 Compared with the green shuttle that is also stroked by oneself, the swinging efficiency of the tentacles is undoubtedly much lower than that of water spray, and it is not suitable for high-speed navigation by nature. Once the speed is increased, the irregular swing itself will bring huge resistance, but the water jet propulsion does not have this concern at all.

　　The weak surface power has always been a major hidden danger in Jinxia City. Dongsheng National Energy has launched a sailing battleship, and it is guaranteed that it will be two or three next time, not to mention the destruction of the West Polar Fleet on 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.
