Heavenly Dao Formula

This kind of air-promoted plant can only survive for a few months. When the vines sprout, they are very delicate, and after being cut off, they can peel off strips of filaments, which are extremely precious materials. Even on World Island, only a few people can afford such clothes.

And when the vines grow up, they will become thicker and tougher. Difficult to process not to mention, 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 high-quality wood, so the aging golden vine in the manual is only listed as a substitute for another fast-growing vine in.

However, when the first batch of samples were sent to Jinxia City, Xia Fan quickly noticed that it was extremely tough and not low in strength, making it suitable for use as a cushion. Especially under the control of elves, it also has a certain degree of clinging ability, and can wrap itself around solid objects.

This idea was immediately applied to the mechanism beast.

Facts have proved that the combination of the two has an excellent effect. The impact force of the skeleton that is no longer rigidly connected is reduced by more than half. The vines wrapped around the outside are like muscles clinging to the bones. Every time they contract, they absorb a lot of kinetic energy and lose pressure. It will be released again at times, which improves the flexibility of the mechanism beast in a disguised form.

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

Of course, the actual benefits obtained after adding cushioning joints are not the only ones, such as wood wear and durability of the astronomical instrument, all of which are improved due to impact mitigation. It's just that these advantages are not so eye-catching compared to the flexibility visible to the naked eye.

Xia Fan had been having a headache about the vulnerability of wood, and the most straightforward solution was undoubtedly to replace wood with metal. But relying on a blacksmith's hammer alone, hammering out a reliable skeleton is definitely a job that counts in years, not to mention the need for mass production in the future.

Now, he has the idea of ​​simply using wood to make the main components. Leaving aside the fact that it is vulnerable, wood has too many advantages—it is easy to process, has many sources of materials, and is light in weight. It can also be repaired wherever it breaks down. I really want to give up the astronomical instrument. Once pumped, the wooden skeleton doesn't feel bad after throwing it away.

"What about the price?" Ning Wanjun asked, "I remember that the exchange price of the golden silk vine is not low."

"Not only is it not cheap, it should be said to be very expensive." Xia Fan smiled, "But the main reason for the high price is that the quantity is relatively small. The seeds produced by the tree spirit are limited, and they will definitely not trigger a large number of such near-luxury seeds on the way to escape." The product of high-quality products. In addition, there are very few new shoots of golden vines, so the elves will naturally 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 shoots. According to Aili, this thing can grow quite well."

"Having said so much, it's time for me to try it?" Ning Wanjun rubbed her hands and climbed towards the organ beast.

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

"It shouldn't be a problem, right?" Xia Fan pondered for a while, "As long as she doesn't use too much force——"

Click!

Before he finished speaking, the organ beast sat on the ground with its legs raised high and its legs split.

"your Highness--"

"Wan Jun, are you alright?"

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

Xia Fan couldn't help covering his eyes. This is the disadvantage of using astronomical instruments as joints. There is no locking mechanism at the joints. As long as the operator does not control it, it can turn more than one circle.

In addition to Golden Silk Vine, there are two other types of seed products that Xia Fan likes quite a bit.

One is phylloxera, which fixes sea sand on the gnarled bottom of tree boats until it forms a soft ground. It is also the basis for the formation of the world island. It can be said that without phylloxera, there would be no living place for the islanders today. Therefore, even if it can neither bear fruit nor be used for sewing or processing, the elves will still transform part of the seeds into root nodules to ensure that the rhizomes under the tree boat can withstand the impact of the waves.

Xia Fan didn't have any ingenious ideas about this, and he used it to grow the same crops. Rhizobium plants are generally mutations caused by symbiosis with rhizobia. In addition to improving soil quality, the biggest effect is nitrogen fixation. And until the invention of the chemical synthesis of ammonia, all nitrogen came from natural cycles, which put most lands at their nurturing limit. It can be said that it was the breakthrough of synthetic ammonia that led to the advent of modern fertilizers, and with chemical fertilizers, human beings 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 element separation is difficult, it is obviously more difficult to obtain chemical fertilizers. Using root nodule plants to provide nitrogen sources is undoubtedly a tricky method. Of course, if it's just an ordinary root nodule plant, the nitrogen production can be said to be negligible, and it is basically impossible to count on it. As a product of tree spirits, phylloxera has a potential far greater than those of ordinary crops—at least he has never seen any kind of grass that can turn sea sand into soil little by little, and on this basis, give birth to a tree boat full of vitality. .

Of course, the specific effect of fattening phylloxera can only be determined by comparing the experimental field, at least it will take a year. But even if the effect is not obvious, it can be used 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 nan, which is placed at the front of the manual, and it is also the "rainwater harvesting grass" that Xia Fan thought.

This kind of plant looks like a shrimp cage, lying on the ground one after another, and can extend hundreds of feet away; the thin one is like a bamboo pole, and the thick one is like a bucket. According to the elves, it has a very wide range of uses on World Island. It can gather rainwater and send water to the residents living in the canopy by internal peristalsis, and it can also pump seawater to help islanders put out fires. In a word, it can be called a biological pipeline, undertaking the important task of water resource distribution in the world island.

The fact that it can pump and drain water alone is attractive enough. Whether it is salt pans to attract tides or farmland irrigation, there is a stage where it shines.

But this is not what really fascinates Xia Fan.

In terms of pumping water, water trucks and overturned cars can do it, but the efficiency is low at most, and people need to step on it, and Jinxia City is far from the point of manpower shortage.

What he likes is the ability of soft bamboo Nan to propel with water.

If this thing grows at the bottom of the cabin and sprays water continuously, wouldn't it become an axial flow pump? If one is not enough, you can come in a row, as long as the more water is sprayed, the greater the thrust the ship will get.

Compared with the green shuttle that also moves by itself, the swing efficiency of the tentacles is undoubtedly much lower than that of the water jet, and it is not naturally suitable for high-speed sailing. Once the speed is increased, the irregular swing of light itself will bring huge resistance, but the water jet propulsion has no such concerns at all.

Weak water surface power has always been a major hidden danger in Jinxia City. Dongsheng Guo can send a sailing battleship, and there is no guarantee that there will be two or three ships 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.
