Broad World

Coming to the basement, Henry quickly started electrolyzing water. The electric energy transmitted from the energy pool is converted into direct current, respectively connected to the bottom of the glass container. A large amount of water is decomposed into hydrogen and oxygen, which enter the magic compressor through metal pipes, and all the liquid gas is packed into a sealed metal tank.

The hydrogen generated by the negative electrode and the oxygen generated by the positive electrode are separated and released. Hydrogen is not only used as the filling gas of the airship, but also can explode violently when mixed with oxygen. Its power is so powerful that it is probably no worse than some ninth-level spells. After several demonstrations, he let the gray dwarves take over the work here, and he returned to the laboratory to start researching the rare items obtained in this adventure.

The first is the shell of the dragon turtle, a material with a hard texture and a smooth surface, which is very suitable for resisting physical attacks and some elemental damage spells. Henry carefully pieced them together and connected them into a complete full body armor. Then I made a large three-layer tower shield and a magic ax hammer for the armor, and finally cast an activation spell, and this very mighty-looking guy stood up.

Henry tried to control the two-meter-tall guy with his hands. The activated armor complied with him, walked a few steps at random, and then demonstrated the movements of raising the shield and slashing. He cast a "fireball technique" on the armor. After the violent explosion and fire, the entire armor had no scars other than a little hot. It seems that in addition to the adamantine golem, there will be another automatic guard that does not need to rest for 24 hours.

It was already dark after finishing this work, Henry hurriedly ate something and went back to his room to sleep. In the next few days, he was completely immersed in the ocean of magical knowledge. Cagan and his people continued to send specially processed steel skeletons to the Mage Tower, and the gray dwarves and golems were also working hard to dig deep pits outside.

When Henry thoroughly read the materials exchanged from the Huber family, it has been more than a month. The huge pit outside the mage tower has already been dug, and the huge steel skeleton outside has been built according to the drawings. Tenoben loudly directed the gray dwarves to connect the steel frames with rivets. It seems that at the current speed, it will be completed in two weeks.

"Cortana, how much rubber and hydrogen are in stock now, is it enough for the big guy below?" Henry looked at the busy crowd and asked Tarling.

"The gas storage is sufficient, and the total area of ​​the rubber has exceeded three times what is needed. However, the gum brought back by the tree spirit is seriously insufficient. If you want more, it is best to send people to collect it deep in the forest."

Henry smiled and touched the stubble on his chin. "Let the people who make the rubber stop working when they run out of all the raw materials, and continue to extract the gas until the two warehouses are full. Then let them stop. These things should be enough for me to build two or three airships of this size." After speaking, he picked up a piece of paper and began to design the power system of the airship. Otherwise, this big guy can only slowly float in the sky.

As far as Henry knows, most of the early airships on the earth used a structure such as a steam engine, a propeller and a tail. However, he didn't intend to invent the steam engine, because this kind of machinery would cause too much damage to the environment and go against the natural harmony of druids. He intends to directly replace the entire machine with an electric motor. At that time, he only needs to install a micro element pool on the airship, and recharge it every once in a while. Because there is a hydroelectric generator set that supplies power around the clock, there is no problem with this consumption.

With this in mind, Henry built four motors in two weeks. According to his design, there are two on each side of the pod of the airship. In this way, even if two of them have problems, the other two can continue to work, and the safety and speed are very guaranteed.

Since it was the first ship, Henry paid special attention to safety work. After all, it is possible to survive a shipwreck, but an air crash basically kills everything as soon as an accident occurs. Falling from a height of thousands of meters, apart from a few spellcasters, even legendary warriors would be smashed into a pulp. Both the rubber and the steel frame were covered with fireproof magic patterns, and the huge air bag was divided into dozens of individual air chambers. Finally, the oversized cabin is fixed below, and the main part of the entire airship is completed.

Henry personally placed the micro-element pool in the strongest room at the stern, the four electric motors were placed separately, and the gray dwarves installed the oversized propeller. The moment the circuit was connected, the motor started to spin, and the strong wind from the propeller almost blew the surrounding iron frames.

Seeing that everything was fine, Henry ordered the golem to add the final tail fin, which is an important steering device for the airship. Soon bottles of hydrogen gas were lifted out and rushed into the airbags with rubber tubes. As the buoyancy increased, the airship slowly began to fly slowly. After the main airbag was inflated, the fixed ropes were stretched tightly.

"Lift some heavy objects up, and call out all the people in the tower. Let's test its load-carrying capacity, and fly around the islands by the way." Henry gave instructions to the gray dwarf leader, and walked into the hangar with Debra.

Tenoben nodded excitedly, turned around and ran towards the mage tower. It didn't take long before all the people inside came out, even the dryad who didn't like to be lively was among them. Following the set up wooden boards, everyone walked inside, they whispered about this huge object, and sighed from time to time.

After Henry saw everyone coming up, he let the golem below loosen the fixed rope, and then continued to inflate the two auxiliary airbags. As the airship slowly left the ground, the people on board cheered. They squatted in front of the glass window, looking at the shrinking Mage Tower, their excitement quickly infected everyone.

When controlling the airship to rise to about two kilometers above the ground, Henry activated the power unit. The generator rotated rapidly with the propeller, controlled the tail to adjust the direction, and this behemoth flew in the direction of Bruwent City. The current auxiliary airbag is only filled with less than one-third of the hydrogen, and if it is full, it is estimated that it can rise to an altitude of 6,000 to 8,000 meters.

"It's an amazing creation. This is the first time for me to fly in the sky of the main plane." Dai Lina walked to Henry and said with a sigh.

Amy nodded in agreement. "It's really great. With this aircraft, we can avoid many dangers in the future, and the speed is much faster than the ship."

"Yes, at the current speed, we only need a quarter of the original time to go to and from the west coast, and the sky is much safer than the sea. In the future, I plan to use it to replace some ships, responsible for transporting valuables and passengers." After speaking, Henry explained the airship promotion plan in detail.

Debra looked at him in surprise and asked, "You mean two more ships will be built soon? My God! This is really a crazy move."

Henry accepted the compliment with a smile on his face. "My plan is to use two ships to trade and transport passengers to and from the west coast. I believe those wealthy merchants and nobles will love this fast and safe way of travel."

The speed of the airship was very fast, and it reached the sky above Blue Winter City in about ten minutes. Countless citizens looked up at the behemoth in the sky, and even the mayor Hawke was startled. He pointed to the sky and asked the guard loudly: "Who can tell me what's going on! Where did the monster in the sky come from?"

The guard pointed awkwardly at a small mark under the airship and replied: "My lord, it flew from the direction of the mage's tower, and there is a mark on the side, which should be the family crest of the Earl."

Hawk narrowed his eyes, and sure enough, he vaguely saw a shield-shaped pattern on the side. But because it is a little too far away, it is really hard to see what is painted. "Now send someone to the mage tower and the lord's mansion to ask what's going on, and ask the city guards to step up their guard just in case."

Just when Hawke was extremely nervous, a pot exploded in the Lord's Mansion. Shikodi and Lily grew their mouths and looked up at the airship. Although they had heard Henry talk about building an aircraft, they didn't expect it to be so big. The always polite butler standing behind also lost his composure, he didn't even wipe the saliva that inadvertently dripped from the corner of his mouth.

"Damn it! I should let him take me up for a flight." Shi Kodi was the first to recover and complained.

"Since it has been built, are you afraid that you won't have to sit on it in the future? I believe Henry will agree with you even if you want to live there." After speaking, Lily rubbed her sore eyes with a smile.

The butler bowed deeply to the two ladies. "If you want to go up, please take me with you. I also want to experience the feeling of flying in the sky once in my lifetime."

Shi Kodi covered her mouth and smiled happily. She didn't expect this old man to have such a cute side. "Of course, the Earl will definitely not disappoint a loyal butler. Let's enjoy the feeling of air travel tomorrow."

Henry stood in the cockpit of the airship and looked down, and soon found the soldiers moving back and forth in the city. "It's really bad. I seem to have forgotten to notify Hawke before taking off. Look at the guards below. They seem to be moving in the direction of the flight."

His words made the three ladies laugh. Debra pointed to the slightly flustered citizens and said, "Look at their expressions, they probably regard this huge flying machine as some kind of monster. You'd better get out of here quickly, or you might launch the siege crossbow later."

This sentence made Henry break out in a cold sweat. He hastily activated the vertical tail to change direction, and soon left the sky over Blue Winter City, and began to fly around the archipelago. Hawke breathed a sigh of relief after watching the airship leave in the sky. This huge unknown object brought a lot of pressure to the city, and he didn't dare to act rashly until the person who inquired about the news came back. (To be continued.)
