"Noah, what are you doing?" Blue Fairy, Daniel, and Nicole broke into Noah's workshop laboratory and asked curiously, "I haven't been out of the lab for several days, why is there a miasma here?" ”

"Sister Blue Fairy!" When the haggard Noah saw Lan Xian'er, he suddenly exclaimed excitedly, "Yes, how did I forget your brewing technique, great, there is a way!" ”

The three of them looked at each other, not knowing what Noah was talking about, and Nicole shouted angrily: "What the hell are you doing, if you continue like this, you will be as crazy as Altai!" ”

Noah, who was most afraid of Nicole, immediately quieted down and said, "I'm improving Noah's airship, and I'm about to make a breakthrough!" ”

"Develop Noah's airship?" Lan Xian'er was surprised, "Noah's airship needs hot gas to vapor before it can rise and fly, in the Marishen planting place, unlike the lava, your airship can still fly?" ”

"So we need to create an environment like steaming so that the airship can climb!" Noah said, "We can burn a fire under the airship, let the hot air pour into the boat, keep the airship constantly supported by the heat, so that we can keep the airship in the air and not fall, we can increase or lower the climb height of the airship through the fire, and then install sails and windmills to adjust the direction of horizontal movement!" ”

Nicole asked curiously, "What do you want the airship to do?" ”

Noah smiled and said: "Your Royal Highness Princess, the development of Fuxing City is because of the convenience of land and sea transportation, Malishen does not have this condition, why can't we think of other modes of transportation, such as the sky!" ”

"You're going to open up a heavenly fellowship?" Nicole laughed and said, "General Noah, how dare you think about it!" How much fuel does your Noah airship need to burn to keep up with the climb, and the more fuel you have to load, the heavier your airship will be, and the less it will be able to fly! Hahaha, it's so funny! ”

Noah shouted angrily, "Your Highness, I am over sixteen years old, and it is not funny that I don't need you to remind me how much fuel to load!" I'm going to continue the experiment now, please get out! ”

"You-" Nicole was angry and funny, but she didn't know what to say, she used to always treat Noah as a child, but now unconsciously, a few years have passed, this child has grown up, and has experienced a lot of things, people and things are changing, time is impossible to go back to the past, and she can no longer stay in the same attitude towards people, things and things. Nicole is extremely embarrassed now, neither to go, nor to stay! She can yell at Higg, play tricks on Daniel and Blue Fairy, and command the revival fleet to gallop the waves, but she doesn't know how to deal with the child who once feared her and now needs to be respected.

"Hahaha!" Lan Xian'er laughed and said, "Aren't you interested in my brewing skills, why do you want to drive me away?" ”

"I've already learned about your brewing device, but I just can't think of it for a while!" Noah said, "It's okay if you don't leave, but you need help me build a new brewing unit, and it's going to be big, let's call it a distillation tower!" ”

Daniel was even more curious: "What do you want to distill for, do you want to make wine?" ”

Noah said, "Purify the fire oil and use it as fuel for Noah's airship!" ”

Lan Xian'er and Nicole were also surprised: "Purify fire oil as fuel? ”

Noah pointed to the jars of black liquid in the laboratory and said, "In the past, we used fire oil, which was used as an auxiliary combustible, and its own combustion capacity was limited!" I found that after the combustion of the oil is completed, there are a large number of non-combustible impurities, and if we can separate these non-combustible impurities from the part of the fuel that can be burned, then we can only have this fuel on the Noah's airship! I have extracted some of the fuel, but the amount is very small, and a lot of the fuel will be lost as air during the extraction process, and it will not be able to be collected! I think it should be possible to collect the lost fuel by distillation. I've done experiments and boiled a pot of water at the same time, using four to five times the weight of dry firewood than essential oils, and the size of the fire is very easy to control! This kind of black oil is abundant around Marishin, and the cost is low, as long as the dwarves can mine it back! ”

Blue Fairy, Daniel and Nicole looked at the bottles and cans in the laboratory in surprise, which contained all kinds of liquids, from dark to light in color, and each bottle and jar had detailed labels, as the great magician, Daniel, knew very well the value of these liquids in the bottles and cans, and said to Noah: "You need to rest now, we will do the things of building the distillation tower, this matter is not in a hurry, many things are still in the experimental stage, you can't collapse your body!" What else do you need besides the distillation column? ”

Noah said, "A lot of dwarves are needed, so mine the fire oil and transport it here!" I also need a lot of lime, and I need the dwarves to mine and burn. There are also a lot of sheep skins, whole skins, at least 50,000 sheets! There is also a large amount of cowhide rope. ”

"Fifty thousand?" Daniel exclaimed, "Do you know how much 50,000 sheepskins weigh, and that a blimp can fly with that bit of essential oil?" ”

"It's up to you to see what you're capable of!" Noah said, "The Alchemy Kingdom can make a flying spaceship, of course, it has the technology to deal with sheepskin, as long as you, the magician, cooperate with me, I guarantee that I can make the sheepskin as thin as silk cloth!" It's a pity that Master Altai is not here, otherwise, with his ability, we don't think we need so many sheepskins! ”

"Sister 50,000 sheepskins will make it for you!" Lan Xian'er said, "All the costs of manufacturing airships can't be paid by the Forest Country, we can pay for it ourselves, and the Noah Airship made by the Forest Country can be used, but the ownership must belong to us!" ”

"No, let Her Royal Highness the princess pay for this fee!" Noah said, "My Noah airship is actually inspired by the Alchemy Country's Qi Swinging Spaceship, and in addition, it also needs to use a lot of Alchemy Kingdom's technology, so this airship should be given to the Alchemy Country, but now we will borrow it for the time being!" Back then, in the Alchemy Country, I promised Her Royal Highness the Princess not to pass on the technology of the Alchemy Country, especially the core technology! ”

Nicole looked at Noah with emotion and said excitedly: "Noah, you want to make Noah's airship for the Alchemy Kingdom?" ”

Noah smiled and said, "Your Highness Princess, some techniques I have already improved, and they are not entirely the techniques of the Alchemy Kingdom, and I also need Her Royal Highness the Princess and Daniel two magicians to fuse my techniques." ”

Lan Xian'er said: "This is a big project, it can't be completed in a while, we must do more work in the laboratory stage!" And Noah's airship is not trivial, it must not be peeped at by others The core technology, otherwise, it will be a disaster for the whole world! ”

Noah nodded and said, "Don't worry, even if the core technology is snooped on by others, it can only be mastered, and I have this confidence." I also don't want Noah's airship to become a killing machine, so we must have the core technology in our own hands! ”

Daniel also said: "We are very happy that you think so! When the time comes, I will personally test fly your airship. Don't say so much, let's go our separate ways! ”

……

Although there is a plan, Noah's airship cannot be made in a short time, and the first thing to solve is the problem of manpower and food! Marishin has only 500 dwarves in total, and there is no industry except to serve the army, so everything depends on foreign supplies! The dwarves must first build a road to the outside world and connect it with the outside world, so that Marishen can truly connect with the outside world, in order to transport supplies from the outside, and to recruit more dwarves. In short, everything in Marishin is not on track. Everything is difficult at the beginning, and Benjamin gives Marishin's renovation task to Lan Xian'er and the other four, and the four of them also know the difficulty of the task.

More than 40 kilometers of mountain roads were built out of the mountains, and although 500 dwarves worked day and night, it was not until a month and a half later that Pantony led the old men, women, children, and children of the Desi tribe to Marishen that it would be completed. Happily, Pantony also brought back more than 300 dwarven slaves, some recruited on the road and some exchanged for jewels in the slave trade.

There were more than 2,000 old and weak women and children of the Desi tribe, plus more than 300 new people and 500 people from Marishen, and the number of Marishen who wanted to open his mouth to eat and drink suddenly reached more than 3,000. Fortunately, the road has been built, and the purchase of supplies and food can be handled by Kavanagh, and Pantoni continues to absorb the surrounding dwarven slave market or recruit dwarven labor, and the original military camp can be lived in with slight modifications, and there is no need to build too many houses.

Only then did Noah Airship really come out of the laboratory and began to enter the production implementation stage.

Some of the dwarves mined nearby fire oil wells and transported them back to the base camp in sealed wooden barrels; Some of the dwarves mined limestone to burn lime, which was then transported back to the base camp as well.

The oil contains a lot of water, which needs to be poured into the quicklime pond to let the quicklime absorb most of the water and then separate it to obtain the fire oil with very little water content, and then put the fire oil into the distillation tower for high temperature distillation, extract the flammable and light fire oil essence from the fire oil, and finally put it in a jar for sealed preservation.

Noah's airship consists of three systems, one is a semi-enclosed airbag made of improved sheepskin and cowhide ropes; the second is the heating system, which burns the fire oil essence by a special furnace and heats the gas to the air bag; The third is the gondola system, which is mainly to carry people and goods, plus direction control windmills.

One of the core technical difficulties is the airbag, which must be made large enough, light enough, not breathable and leaky, and the flexibility and heat resistance requirements are also very high, so in addition to requiring the dwarf to sew skillfully, many magical elements must be added to melt the entire airbag into a whole.

50,000 sheepskins, if not improved, at least more than 50 tons, plus the weight of cowhide ropes, burning furnaces and hanging baskets, it is impossible to make the airship fly no matter what, so the core technology of the airbag is to improve the sheepskin cowhide rope, so that the total weight of the sheepskin and cowhide rope is greatly reduced, so that it is possible to make the airship take off.

According to Noah's design calculations, the airship airbag made will have a diameter of nearly 100 meters, which is simply a super behemoth.
