In the next few days, the test of the personal aircraft of Wang Mumu and other thirteen people went smoothly, and a few young people were high up for a while, looking into the distance; After a while, it will fly horizontally, the ground effect, the wind and water will rise, the waves will be chopped, and the fun will die, and the madness will not end. Hu Sanniang also slapped little Helen's head and said, "Princess Golden Diamond, my little apple, don't you want to make a mistake?" ”

After a few days, Wang Mumu saw that there was no problem with the aircraft, and after making some engine adjustments, he let the eldest princess, Yuwen Rounu, Hu Nanbei and others also get on it. Even Shen Zhang's family was strongly requested by herself, and Wang Mumu agreed to take off under the escort of her two sons and prospective daughter-in-law. As a result, in March and April of 1087, more than 100 human aircraft soared in the sky on the northwest sea of the Great Ryukyus. Some fly high like big birds, some fly through the beams and pillars like birds, some glide close to the water like water birds, and some soar into the sky like high birds. For a while, the trapeze in the sea and sky became a hot spot in the Ryukyus.

Fingers wrestling, Wang Mumu said, my wedding with Hu Dong is scheduled for the Mid-Autumn Festival next year, because, I want to inform many international friends that the distance is far away, the time is in a hurry, and people are too late, and they also have to make some preparations for international trade and prepare some silver. So, what international friends is Wang Mumu going to invite?

The first thing Wang Mumu wanted to invite was the Liao people. Although the Song State has always regarded the Liao people as strong enemies in his heart, but, at least, on the surface, everyone has an alliance with the Yuanyuan, so it is normal for each other to be allies and have diplomatic contacts. As for Wang Mumu's selfishness, he wanted to once again show whether he could promote the Liao and Song Dynasty to join hands to fight the enemy, mainly against the rising Jin.

Wang Mumu invited Xixia this time, because, since the death of Song Shenzong, the old party came to power, and recently, Song Xia was very friendly on the surface. In addition, the Tangut people captured by Wang Mumu in the past saw that the Liao people, who were also captives, lived very nourishingly here, especially the injection of exoticism, which made these old hats adrenaline soaring, repeatedly expressed their submission, and asked to return to China to recruit rebels like the Liao. Therefore, Wang Mumu thought that he could probably open this way.

Wang Mumu transferred Xiao Zhixian from Luzon and asked her to envoy Goryeo and Tamna; Wang Mumu transferred Xiaohua Cheng and asked him to send an envoy to the Wa Kingdom.

Wang Mumu transferred Maiba and Geng Haoshan from the island and asked him to send envoys to the Tibetan tribes bordering the Song State and the Dali Kingdom, as well as the Western Uighurs in Western Xia, the Huangtou Uighurs in the southwest of Western Xia, the Uighurs in Western Xia and Hara Khan in Western Tibet, and the Ghaznavid Dynasty and the Seljuk Empire in Greater Iran.

Wang Mumu handed over his dealings with Southeast Asia to Xiao Hairui and Xiao Shanni, targeting Champa (South Vietnam), the Bagan Dynasty (Burma), the Angkor Dynasty (Cambodia), the Cochin Li Dynasty (Vietnam), the Sriwijaya Kingdom (Indonesia), and India.

Wang Mumu asked Hudong to take time to return to the island to contact the countries of the Mediterranean: the Eastern Roman Empire (i.e., the Byzantine Empire, the Flak Kingdom), the Green Food, the Kingdom of Serbia, the Principality of Kievan Rus (Russia), the Kingdom of France, the Holy Roman Empire (Germany), the Italian Republic of Cities, and the Arab Empire. And, of course, the kingdom of Rhodes in Husse. Europe is now very chaotic, one is the religion involved in politics, and the other is the change of suzerain. For example, Serbia, France, Germany, Italy, including the Serbian state in eastern Hudong and the Rhodes state in western Huzhou, all recognized Byzantium as their suzerain. Therefore, the invitation from Europe is mainly the Eastern Roman Empire, which the Song people called the Fula.

Of course, the most important invitations were given to the top boss of the sea state, the Great Song, to the Ryukyu Kingdom on the Ryukyu Islands (although the king of the Ryukyu Kingdom was temporarily replaced by Wang Mumu), to the Luzon Kingdom of Lü Dongbin, and to the Siam Kingdom of Little Helen (in preparation).

Wang Mumu sent out invitations in the name of the wedding of King Jinghai, the governor of Yipin Haizhou Prefecture of the Song Kingdom, and Princess Ruth, the queen of Sai Island.

Wang Mumu for this big wedding, in addition to the innovation of the form of the rose wedding collective wedding, he already has two eye-catching artifacts of a personal aircraft and a radio receiver, he also wants to build a bigger thing, build a project and a building, so as to show himself, deify himself, market himself, deter local tyrants, suppress strong beams, and surrender to wealth and nobility, so as to achieve the purpose of replacing fire with the Cold War, defeating barbarism with civilization, replacing blood with sweat, and replacing military exercises with showing strength.

Wang Mumu patted his head, this thing, not only can be made by himself, but also try to be as advanced as possible to be inconceivable to others, thinking and thinking, he finally came up with an idea, Wang Mumu decided to build a musical fountain on the welcome square at the gate of Harvard University.

To create a musical fountain, one is to have music, which, no problem. Wang Mumu had already brought back all 2,000 students and soldiers of the marching band from Hujiazhuang to Ryukyu. If you want music, you can play it live. Its own electronic amplification equipment is also accompanied by radio equipment, so this piece is no problem.

To create a musical fountain, the second is to have a fountain, and the fountain is formed by a water pump. And need to convert the rhythm and intensity of the music into a control signal, the different frequencies of the music are processed by the single-chip microcomputer and sent to the control end of the frequency conversion motor, this signal controls a voltage control device again, after the power supply passes through this voltage control device, the output voltage also changes with the tone, rhythm and strength of the music, and then controls the pump motor, changes its frequency to change the speed of the motor, also changes the pressure of the water pump, the water sprayed has a high and low change, and is controlled by several sets of equipment to a plurality of nozzles.

For Wang Mumu, there is a big problem with this piece, he now has a motor but does not have a frequency conversion motor, he now has a semiconductor but does not have a single-chip microcomputer. However, this is not difficult for Wang Mumu, Wang Mumu has a large group of hard-working, diligent and loyal student soldiers, Wang Mumu spent a lot of money on the structure, under the nozzle of the water spray pool, that is, in the basement of the bottom of the water spray pool, he is equipped with a student soldier for every 1 nozzle, and controls a rocker, which can be rotated in a 360-degree plane, so that the water group can do various shapes; It also controls one set of two rotary valves connected in series and parallel on the water pipe to control the size of the water flow and the amount of diversion to control the height of the water jet. These student soldiers were all wired to convey the melody, rhythm, and strength of the commander-in-chief and the music to each person. Theoretically, this system is no worse than the intelligent electronic control system in the previous life, and in practice, if you don't make mistakes, these student soldiers have to be trained.

To create a magnificent musical fountain, you also need to have a 3D animation design with a laser. For this reason, Wang Mumu brought Monet and others from the Academy of Fine Arts. Wang Mumu roughly introduced how the laser music fountain in his brain became a magnificent waterscape fountain, which includes computer technology, laser technology, holographic technology and garden waterscape art, etc., which is a garden art shape with a high degree of unity of light, sound, water and color. Among them should be a galvanometer scanner and a controlled all-mirror with its axis of rotation perpendicular to each other. In the continuous tumbling motion of the space, the laser beam is repeatedly scanned on the water curtain, and the light spots are constantly reflected (scattered) in motion, showing specific patterns. Spot scanning, on the other hand, takes less than a tenth of a second for a week, and text, images, and animations appear on the spot due to the human visual persistence effect.

Wang Mumu told the principle of the waterscape fountain and the pursuit of the goal, but due to the constraints of the conditions, he now does not have computers, lasers and holographic technology, Wang Mumu on the ground, from low to high, Wang Mumu first asked the students of the Academy of Fine Arts to replace the water screen with the screen, on the fountain slide lantern. This is not difficult, but it is necessary to change the tendency of the Academy of Fine Arts to strive for excellence in recent works, and change all the graphics to simple stick figures.

In the second step, because the water screen is larger than the silver screen, the slide image can be adjusted to change the size, so, preliminarily, let the stick figure move simply.

Third, because the water screen is much larger than the silver screen, the entire slide projector can be shaken and rotated when the slide projection is projected, so that the stick figure can gallop and deform on the water screen. But these changes are still too low-level. If it is a horse, it can go from one end of the water curtain to the other, and there is some feeling of near and far and some deflection of perspective. However, the horse's four legs had not yet run.

In the fourth step, Wang Mumu took the horse as an example and asked to set up a large turntable before projecting the light source, and the center line of the turntable was parallel to the light column. There are 24 frames of a horse running continuously on the turntable, and the turntable rotates at a speed of one revolution per second, so that the horse can run smoothly. And so on, the dance of people, the flight of birds, the swimming of fish, the scattering of clouds, the swaying of trees, the chopping of knives, the shooting of arrows, etc., etc., can all be realized. The size and number of frames of the turntable can be adjusted by the speed of change of the object. For specific data, you can play and explore by yourself.

In the fifth step, Wang Mumu called the students of the School of Architecture and accepted the task together with the students of the Academy of Fine Arts, that is, to arrange the civil engineering support for the construction of a musical fountain. Hu Erniang was most interested in this, she flew in the sky by little Helen, and plunged into the engineering drawings by herself, becoming the project manager of the civil engineering sub-project of Wang Mumu's music fountain project.

Wang Mumu's musical fountain was built on the welcome plaza inside Harvard's main entrance. Wang Mumu's synopsis is, such as the monumental viewing platform is a bit like a very beautiful and luxurious three-tier wedding cake, the top layer is based on the appearance of the eldest princess Zhao Qianyu Zhao Qiannu Lin Mo Niang white bronze statue, wearing a costume is the crown of the Song Dynasty first-class lady, its demeanor is not only the great mercy of Guanyin, but also respectable, amiable, lovely sage Mazu, or loving, inspirational, tolerant, fraternity of the Hongling fairy, her feet have famous mountains and rivers and oceans, expressing the Chinese culture and the oriental marine culture, She also has a net bottle and a willow branch, similar to Guanyin Bodhisattva. Standing behind the eldest princess are Yuwen Rounu and Hu Sanniang, who look like a literary girl and a martial girl, and they are also a bit like a jade girl and a dragon girl; It's just that there is no golden boy.

On the second layer of the cake, there are four bronze statues to be molded, that is, the southeast and northwest of Hu, but now one is molded first, that is, the statue of Hudong. Wang Mumu explained to Hu Dong and said, although the eldest princess and other flowers bloomed three times, it was given by the emperor for marriage, and you should be one step later, but in my mind, as long as you become my woman, there is no importance. The reason why there are layers here is entirely due to the structure and aesthetic composition of the building, don't you mind.

Hu Dong immediately said that he could be accepted by the prince, and he was overjoyed, and he didn't have any other plans at all. It is already unexpected and flattered that this "cake" can have its own share.

The third layer of the cake is the painting wall, which will record Harvard's singing, crying and memorable deeds in the form of pictures and texts. The existing themes are: "Aspirin", "Cement Ship", "Whale Fight", "Swiss Bank", "OECD", "Gold Shines", "Classic Naval Battles", "Shoot at Me", "Three Female Monkeys", "The Battle of Rhodes".

In front of the big cake is a large pool, 100 meters long, 20 meters wide, and there is a horizontal row of nozzles in a distance of 80 meters on the inside, with a spacing of 50 cm, a total of 8,241 nozzles; There is also a nozzle matrix in front of it, 30 meters long, 20 meters wide, and the spacing is the same as above, a total of 2,501; So, if this musical fountain is performed in the best condition, there will be nearly 10,742 nozzle control personnel alone, so, with the lighting, animation, and music, this performance team is terrifyingly large, because it has 14,000 people!

Wang Mumu built a 35-meter-long corridor on the left and right sides of the "three-layer cake", in addition to being available for leisure, stopping, staying, resting, and reading, there are many square holes on its 1-meter-high foundation, and these holes are partly ventilation holes and partly projection holes. Wang Mumu wants that when the water curtain is formed, the performance and projection of the animation will be rear projection, which is based on: if it is not a rear projection, like a movie theater, the projector projection is in the same direction as the audience's line of sight, then the audience sees the reflected image of the water curtain; However, if the projector is facing the audience's line of sight, with a water curtain in between, the audience will see a transmitted image. Comparing the two, the image quality is definitely better than the latter, but when the audience is watching in the same direction as the projected light column, the audience will undoubtedly realize that the image on the water screen is projected from the luminous place; And the latter, because the audience does not know that the image on the water screen is produced by the projector, then, at this time, if you need to explain that the image is aquatic, that it comes with the water, that the spirit in the water is shining, or that the spirit is shining in the water, then this is not very helpful for creating gods and engaging in some feudal superstition?
