Coming to the basement, Henry soon began to electrolyze water. The electrical energy transmitted from the energy pool is converted into direct current, which is connected to the bottom of the glass container. A large amount of water is broken down into hydrogen and oxygen, which are passed through metal pipes into the magic compressor, and the liquid gas is all packed into sealed metal cans.

The hydrogen produced by the negative electrode and the oxygen produced by the positive electrode are separated, and the hydrogen is not only used as the filling gas of the airship, but also can cause a violent explosion when mixed with oxygen. Its power is so great, I'm afraid it's not much worse than some ninth-level spells. After a few demonstrations, he had the grey dwarves take over the work, and he returned to the lab to begin researching the rare items he had obtained from this adventure.

The first is the Tortoise's shell, a hard, smooth material that's perfect for fending off physical attacks and some elemental damage spells. Henry carefully pieced them together and joined them together to form a complete full-body armor. Then he made a large three-tiered tower shield and a magic axe for his armor, and finally cast a activation spell, and the mighty-looking creature stood up.

Henry tried to control the two-meter-tall creature with it, and the activation armor complied with him, walking a few steps at will, and then demonstrating the action of raising the shield and slashing. He performed a "fireball technique" on the armor, and after the violent explosion and fire, the entire armor was not scarred except for a little burn. It seems that in addition to the Adamantite Golem in the future, there will be an additional automatic guard who does not need to rest twenty-four hours a day.

It was already dark after the work was completed, and Henry hurriedly ate a little and went back to his room to sleep. For the next few days, he was completely immersed in a sea of magical knowledge. Cagan and his people are endless. Send a specially treated steel skeleton to the Mage Tower. Grey dwarves and golems were also digging deep pits outside.

When Henry thoroughly read the information exchanged from the Hubbell family. It's been more than a month. The huge pit outside the mage tower has already been dug, and the huge steel skeleton outside has begun to be built according to the drawings. Tenoben commanded the gray dwarves in a loud voice, riveting the steel frames, and it seemed that they would all be completed in two weeks at the current rate.

"Cortana, how much rubber and hydrogen are in stock now, is there enough to use the big guy down there?" Henry asked Taling, looking at the busy crowd.

"The gas storage is abundant, and the total area of the rubber is already more than three times what is needed. However, the gum brought back by the tree spirit is seriously insufficient, if you want more. It is better to send someone to collect deep in the forest. ”

Henry smiled and touched the stubble on his chin. "Let the rubber makers use up all the raw materials and stop working, and the gas will continue to be extracted until the two warehouses are full. That's enough for me to build two or three airships. After saying that, he picked up a piece of paper and began to design the power system of the airship, otherwise this big guy would only float slowly and leisurely in the sky.

As far as Henry knows, most of the early airships on the earth use a steam engine plus a propeller and a tail. However, he did not intend to invent the steam engine, because such a machine would be too damaging to the environment and contrary to the natural harmony of the druids. He plans to replace the entire machine directly with an electric motor, and when the time comes, he will only need to install a miniature elemental 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, this consumption is no problem at all.

Come to think of it. Henry built four electric motors in two weeks. According to his design, two were placed on each side of the airship's cabin. So even if two of them go wrong. The other two were able to continue their work, and the safety and speed were very assured.

Because it is the first ship, Henry attaches great importance to safety work, after all, it is possible to survive the shipwreck, but the air crash is basically dead as soon as it happens. Falling from a height of thousands of meters, even legendary warriors will be smashed into a pulp except for a few spellcasters. Both the rubber and steel skeletons were covered with fire-resistant magic patterns, and the huge airbags were divided into dozens of individual air chambers. The oversized cabin at the end of the day is fixed underneath, and the main part of the entire airship is completed.

Henry himself set up a pool of miniature elements in the sturdiest room at the stern, four electric motors were placed, and the grey dwarf installed the oversized propellers. The moment the circuit was turned on, the motor spun rapidly, and the strong wind set off by the propeller almost blew the surrounding iron frame into it.

Seeing that everything was fine, Henry instructed the Golem to add the rearmost tail, which was an important steering device for the airship. Soon bottles of hydrogen were lifted out and rushed into the air bags with rubber tubes. As the buoyancy increased, the airship slowly began to fly slowly, and when the main airbag was inflated, the fixed rope was already tightened.

"Carry some heavy loads up, and call out all the people in the tower. Let's test its load capacity and fly around the archipelago by the way. Henry instructed the leader of the grey dwarves as he and Debra stepped into the warehouse.

Tenoben nodded excitedly, turned around and ran towards the Mage Tower. It didn't take long for everyone inside to come out, even the dryads, who had always disliked the hustle and bustle. Along the planks that had been erected, the crowd walked inside, whispering about the huge object, and from time to time let out a sigh.

When Henry saw everyone coming up, he let the golem below loosen its rope and continued to inflate the two auxiliary airbags. As the airship slowly left the ground, the people on board let out a cheer. They lay in front of the glass window, looking at the mage tower that was shrinking little by little, and their excitement quickly infected everyone.

When controlling the airship to rise about two kilometers above the ground, Henry activated the power plant. The generator spun rapidly with the propeller, controlled the tail to adjust its direction, and the behemoth flew in the direction of Broomt. The current auxiliary airbag is filled with less than a third of the hydrogen, and if filled, it is estimated that it can rise to an altitude of 6,000 to 8,000 meters.

"What an amazing creation, this is the first time I've flown in the skies of the main plane." Dai Lina walked up to Henry and sighed.

Amy nodded in agreement. "It's really great, with this craft we can avoid a lot of dangers in the future, and it's much faster than a boat."

"yes, at the current rate, we can get to and from the West Coast in a quarter of the time, and the skies are much safer than the sea. In the future, I plan to use it to replace some of the 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 will be built soon?" Oh my God! It's a crazy move. ”

Henry accepted the compliment with a smile on his face. "My plan is to use two of them to trade and transport passengers to and from the West Coast. It is believed that wealthy merchants and aristocrats will love this fast and safe way to travel. ”

The speed of the airship was very fast, and it took about ten minutes to reach the sky above the city of Bluvent. Countless citizens looked up at the behemoth in the sky, and even Mayor Hawke was shocked. He pointed to the sky and asked the guards in a loud voice, "Can anyone tell me what is going on?" Where did the monsters in the sky come from? ”

The guard awkwardly pointed to a small mark under the airship and replied, "My lord, it flew from the direction of the Mage Tower, and there is a mark on the side, which should be the family crest of Lord Earl." ”

Hawke narrowed his eyes, and sure enough, he saw a shield-shaped pattern faintly on the side. But because it's a little too far away, I can't really see what is being drawn. "Now immediately send someone to the Mage Tower and the Lord's Mansion to ask what's going on, and let the city guards strengthen their guard just in case."

Just when Hawke was nervous, the Lord's Mansion also exploded. Poety and Lily looked up at the airship with their mouths grown, although they had heard Henry say that they wanted to build a flying machine, but they didn't expect it to be so big. The butler, who had always been polite standing behind him, also lost his temper, and he didn't even wipe the saliva that flowed from the corners of his mouth inadvertently.

"Damn it! I should have asked him to take me up for a lap. Sykodi was the first to come back to her senses and complain.

"Now that it's been built, I'm afraid I won't have to sit in the future. I'm sure even if you want to live on it, Henry will agree. After saying that, Lily smiled and rubbed her somewhat sour eyes.

The butler bowed deeply to the two ladies. "If you're going up, be sure to take me with you, and I want to experience the feeling of flying in the sky once in my lifetime."

Shi Kodi covered her mouth and laughed happily, she didn't expect this old man to have such a cute side. "Of course, the Earl will not disappoint a loyal butler, and tomorrow we will go and enjoy the air travel."

Standing in the wheelhouse of the airship, Henry looked down and soon spotted the soldiers moving back and forth in the city. "It's awful, I don't think I forgot to inform Hawke before I took off. If you look at the guards down there, they seem to be moving in the direction of the flight. ”

His words made the three ladies laugh, and Debra pointed to the slightly flustered citizens and said, "Look at their expressions, eighty percent think this huge flying machine is some kind of monster." You'd better get out of here, or you'll probably be firing the Defending Giant Ballista in a moment. ”

This sentence made Henry break out in a cold sweat instantly. He hurriedly maneuvered the tail to change direction, and soon left the sky over the city of Bluvent and began to fly around the archipelago. Hawke breathed a sigh of relief after watching the airship in the sky leave, this huge unidentified object had brought a lot of pressure to the city, and he didn't dare to act rashly until the person who inquired about the news did not return.
