The rooster is dawning, the east is white, and today is the fifth day of the wedding. Nominally, today is the day of "Na Zheng", the eldest princess said, many of our brides and grooms are orphans, and they are poor and white when they come to Ryukyu. In order to ensure openness, fairness and justice, those who win the lottery will have two copies of their room tickets, commonly known as male and female tickets. In order to improve the status of women, this morning's lottery is limited to women, and only female tickets can be received after the medium number; This afternoon, the male ticket will be divided, and the male will receive the corresponding male ticket with the female ticket; Then both parties will go to collect the keys with the male and female tickets stamped with the re-examination seal. This is a big deal for Harvard students. But this matter has nothing to do with Chinese and foreign guests, except for envy, jealousy and hatred. Therefore, Wang Mumu brought a group of 200 guests to his cement aircraft carrier, bathed in the morning light, and explained the use of goods to them.

Most of the 200 Chinese and foreign guests boarded Wang Mumu's cement aircraft carrier for the first time. This aircraft carrier, No. 999, is the first bamboo-reinforced steel fiber cement aircraft carrier built by Wang Mumu, with a length of 220 meters, a width of 46 meters, a height of 16 meters, and a tonnage of 70,000 tons. It is powered by 4 steam engines and 4 steam boilers, with 4 shafts, 4 propellers and two rudder propulsions.

Wang Mumu and his entourage took the elevator directly on the deck to get on the 106╳280-meter "doctor's hat" on the top of the ship. Today's "doctor's hat" has been emptied of the original airboat, and today here, Wang Mumu is going to teach Chinese and foreign guests how to use hot air balloons.

The most eye-catching thing for Chinese and foreign guests is all kinds of things that fly in the sky, especially Ye Tao of the Great Song Dynasty, who always has a bit of the taste of the suzerainty and the central leadership, so he does not discuss with the head of the group to the queen mother, and has been pestering Wang Mumu to ask for an artifact that can make people fly to the sky. He has privately communicated with guests from all over the world, and he thinks that it can be as small as a personal aircraft; airships as large as 53 meters long and 10 meters in diameter; It is even more huge to a wingspan of 156 meters and a fuselage of 156 meters; There are also fast and fast monsters, all of which are very good, why don't you ask for them? Others, on the other hand, are behind, and those who want to follow up can follow up.

In this era, Harvardians are the only ones who can rise to the skies. In the face of everyone's eyes, we must stick to this core cutting-edge technology, but also take care of the face of the mutual organization, and not be too rigid, so Wang Mumu launched this hot air balloon.

Wang Mumu introduced to the guests and said that the hot air balloon is composed of three parts: a balloon, a hanging basket and a heating device. The ball skin is now made of rubberized silk and is lightweight, but also strong and breathable. The gondola is made of rattan and has a cushioning effect when landing. Four fuel cylinders are placed at the four corners of the gondola, and instruments such as thermometers, altimeters, and of course sandbags. The burner is the heart of a hot air balloon......

Wang Mumu knew that in his previous life, there were those who burned large-scale compressed gas or liquefied gas, and there were those who burned gasoline spray furnaces, which involved compressed gas, which was not economical and not conducive to technical secrecy. Wang Mumu is very thoughtful about the burner of this hot air balloon, and after experimental testing, he finally selected and eliminated the open gasoline furnace that is almost directly combusted; All kinds of external pressure gasoline furnaces have been eliminated; Elimination of unsafe tubular gasoline furnaces; The self-heating type gasoline spray furnace with complex aftercare treatment has been eliminated; Flue self-injecting gasoline furnaces were eliminated; A self-vaporizing gasoline injection furnace based on the previous life was selected. The shape of this furnace is very simple, its section image is a "concave" word, the line of the concave word represents the section, of course, the regular drawing method of the line should actually be a double thick straight line with a 45-degree oblique angle of fine solid cross-sectional line. In the "concave", the inner and outer "U" with a diameter of 200 mm is very small, only about 0.8 mm, while the upper and lower clearances between the inner "U" and the outer "U" are about 15 mm. The 628 mm long circumference connected to the upper part of the inner and outer "U" is covered with 63 small holes with a diameter of 0.8 mm. This 250 mm high self-evaporating spray furnace is deceptively simple, but the machining accuracy is very high, which is used to ensure the excellent combustion performance of the furnace.

The working state of the furnace is as follows: before starting, ignite the gasoline that has been placed at 35% of the elevation in the inner "u"; Because there is a large hole at the bottom of the inner "U", there is gasoline at the bottom and in the gap between the inner and outer "U"; The burning gasoline heats the inner wall of the inner "U" (note: the furnace is made of 0.5 mm aluminum alloy with good heat transfer), so that the high temperature inner "U" quickly vaporizes the gasoline between the inner and outer "U"; The vaporized gasoline is ejected from 63 small holes in the upper part of the inner and outer "U" and ignited by an open flame in the center of the furnace; The ring-shaped flame deprives the center of the furnace of oxygen, so the central flame with low combustion efficiency immediately extinguishes itself; In this way, the self-vaporizing spray furnace has entered an ideal working state of high efficiency and energy saving.

Of course, the outer "U" bottom of the "concave" of the self-gasifier is connected to the fuel cylinder, and the furnace is also equipped with a flame regulator, that is, a 200.4 mm ring with a small and large receding spike from 0.3 to 2.6 mm. There are three types of rings, with spikes of 21, 42, and 63. Understood? These three rings can be put on or swapped to make two-thirds of the flame burn, or one-third burn, or extinguish the flame of the furnace.

Wang Mumu positioned this furnace as a gasoline stove, that is, a furnace that burns gasoline. This makes it necessary for users to use this hot air balloon normally and correctly, and to buy gasoline that is monopolized by flow, if any smart person wants to replace gasoline with other fuels, even coal and firewood. However, the precious hanging basket space will be lost a lot, or the time in the air will be shortened a lot.

Wang Mumu's furnace seems simple, but in this era, absolutely no one can imitate it. First of all, no one has aluminum alloy. Smart people use copper, the processing accuracy, roundness and tolerance, no professional machinery can not achieve it. Even if you make a similar copycat, even if you can eventually vaporize and burn, the flame will definitely be two-thirds lower......

Li Daocheng and Li Changjie, who were in Jiaozhi, saw that Wang Mumu finally let go of the artifact, and hurriedly chased after him, saying, can this thing fly into the sky? How can I fly into the sky? Teach us! Let's demonstrate!

Wang Mumu asked the Harvard air force to explain and demonstrate to the Chinese and foreign guests step by step how the hot air balloon was folded into a quilt to be correctly unfolded, spread out reasonably, pick open the air inlet with a bamboo pole, ignite the self-vaporizer and wait for it to be normal, and then use the air duct to send hot air into the balloon, and as the balloon expands and expands, carefully protect the fire with fine barbed wire to prevent the balloon from burning the balloon. Finally, the bulging balloon lifts off with the basket.

Xiao Xiamo of Liao, Gao Shengtai of Dali, Zhangxiong of Guge, and Ali Gu of Qingtang all wanted to go to the sky to see, so they asked, can we go to heaven with these student soldiers?

For the guests' requests, Wang Mumu asked each hanging basket to stay six air troopers and bring three more guests. After liftoff, the aviation unit also taught the guests how to use the tension of the sling and the position of the sandbag to control the direction of the balloon's flight. Finally, the application of parachutes in a state of emergency, the landing of curved bodies, etc., were explained and demonstrated, and the three air forces also parachuted directly from the hot air balloon. The people in the hanging basket once again experienced the inverse relationship between weight and height......

At this time, Wang Mumu's side Jiang Sangge, Fairy Jima, Shouyuan Yijia, Wu Liugui, Qun Tuo Biluo, Tuo Pan Yali, Pan Changjiang, Han Zhongli and others came to inquire about the specific purchase price, Wang Mumu pushed the sale of the hot air balloon to Zhong Yidong around him, and promised to give 100 liters of gasoline and 100 packs of windproof safety matches for each ball, plus ten parachutes, priced at 1000 grams of gold.

When the Chinese and foreign guests saw the small victory in the first battle, they wanted more advanced power boats and monsters. The princess of Babylon said, I can order ten of these airships a year!

Wang Mumu said, you can't become fat by eating in one bite, you come step by step, when you are familiar with it, there is no fear of heights, and when you hold a rose wedding next year, I will talk to you about upgrading, okay?

Now, Boccaccio in Italy, Uncle Mar in France, Everdeler in green, Iraq and Tirac in Ghaznavid are all pestering Wang Mumu, and now, everyone has an artifact that can fly into the sky, and they want something to open in the sea. Nowadays, Wang Mumu's cement ship is 6,000 tons, the ironclad ship is 17,000 tons, and the cement aircraft carrier is 70,000 tons. Whether it's from the military, logistics, or shipping safety, who doesn't want it? In this regard, Wang Mumu can't be as generous as a hot air balloon. Wang Mumu's countermeasure is, everyone, I will sell all kinds of trade with you, and I will deliver them to the door; I buy it, and I pick it up. Trade with me, don't think about logistics. In addition, I will organize a shipping company to undertake logistics business between countries. And so on, don't you think it's better to build a ship than to buy one? Is it better to buy a boat than to charter one? Is chartering a ship better than consignment? So, can this question be passed?

Khayyam of the Seljuk Empire, Vladimirovich of Kievan Rus, Stankovic of Serbia, and Adidas of Holy Rome were very scheming, and although they had not come into contact with the telegraph, they all knew that Harvard had a secret weapon for transmitting information over long distances. Especially with the recent disclosure of broadcasting equipment, the first thing delegations do in the morning in a few days is to exchange whether the music you heard in your room last night is the same as what I heard in my room. For comparison, the guests are still learning to sing famous Chinese and foreign songs, and radio broadcasting has greatly enriched and promoted the process of world culture, and music without borders has been launched. Now, on behalf of the representatives of various countries, several of them proposed to Wang Mumu that we also want these things.

Wang Mumu's reply was that he is now willing to build a radio broadcasting network for the people of the whole world, and initially envisages setting up points in the following places, with the principle that the distance between points is not more than 800 kilometers, promising to provide telecommunications services for all countries, and forecasting that weather forecasting will be carried out on a trial basis after one year of exploration. These stations are located in Luzon, Hangzhou, Hainan Island, Nansha Island, Kuala Lumpur, Cochin, Cham, Siam, Angkor, Bagan, Pandia, Djibouti, Karachi, Dubai, Qatar, Basra, Baghdad, Sai, Istanbul, Cairo, Rhodes, Rome, Paris, Berlin, Tirana, Budapest, Kyiv, Minsk, Moscow. The countries provided the land, logistics and security, and Harvard was responsible for the construction and opening and operation. At this stage, this project is only used by the royal family and the authorities of various countries, and for the public, it is a special forbidden area, refusing to visit and comment, and the computer room is equipped with a self-destruct device. In view of social integration and legitimacy, the points are intended to take the form of mainstream local religious buildings, such as Buddhist temples, Catholic houses of worship, and Islamic mosques. We will try to respect the architectural style of the religious houses of all religions and denominations. Catholic churches will be Gothic, Baroque, Rococo, etc., and will have a lot of very ornate sculpture decorations, and there will be a lot of sculptures inside, as well as icons. The whole layout is in the shape of a Greek cross that is as long as horizontal and vertical or a Latin cross that is as long as horizontal and vertical. Buddhist buildings like Chinese palaces often have pagodas. Mosques in Islam have domes and towers around them, and individual domes are also found in some churches, but only mosques are with them. The interior is also very ornately decorated, but it is all flat and there will be no three-dimensional works such as sculptures. For the spires of Catholic churches, Buddhist pagodas and Islamic pagodas, these are all building supports for the radio transceiver antenna that Wang Mumu needs. As for the connotation of these religious houses, in addition to our telegraph stations, radio stations, transit stations, relay stations, meteorological stations, health service centers, turnover and trading points that control commodities, and loan and mortgage banks for huge financial resources, we can also use high-profile buildings as places for religious activities......

Kaspersky of the Eastern Roman Empire asked, our church of Elena or St. How about you move in after the renovation of Sofia Cathedral?

Stankovic from Serbia asked, "How about you move in after our Serbian church is renovated?"

Vladimirovich of Kievan Rus' asked, "How about you move in after the renovation of our Isa-Kyiv Cathedral?"

Boccaccio in Italy asked, "How about you move in after the renovation of our Basilica of Our Lady of Flowers?"

Pan Changjiang of Pandia asked, how about you move in after our Nalanda Temple is renovated?

……

Chinese and foreign guests also fancy Wang Mumu's "spear" and "shield". If you want Wang Mumu's weapons and armor, in fact, the * person only thinks that these full-body armors are exquisitely made, and they don't know their offensive performance of electric shock and electric heat. As for dagger guns and saber guns, they are just sharp daggers and sabers, or magic weapons of Harvard immortals, and they don't know that bullets will fly out of them. Wang Mumu agreed to lift the ban on the first generation of full-body armor, which was not charged and did not stop the mouth, but its good protective performance was still full of praise.

As far as Wang Mumu is concerned, because he has completely mastered air supremacy and has all kinds of javelins and hammer balls, Wang Mumu no longer considers the development of various cannons in his armament. In fact, in naval battles, 90% of the shells are bombarded into the sea, and the efficiency is too low. Wang Mumu agreed to sell solid plain javelins and chain balls and solid plain daggers and sabers, although without stuffing, little Helen's dagger broke Wu hook and made a deep impression.

The Chinese and foreign guests also took a fancy to Wang Mumu's medical medicine, and Wang Mumu agreed to have two doctors, one male and one female, in each of the above-mentioned "points". Wang Mumu subdivided aspirin, penicillin, artemisinin, etc., complicated it, and released it in a controlled manner.

For the needs of Chinese and foreign guests, starting from the general direction of favorable flow, Wang Mumu began to open the door cracks under the premise of protection. Wang Mumu's small abacus is very good, however, Seong lost his horse, how did he know that his crack in the door would become a catalyst in the future, and became a fuse for the European Crusades......
