When the helium tanks that were no longer needed for the aerospace ship were transported out by the staff of the Goblin Chamber of Commerce, a large amount of modification materials were also continuously transported into the elevator.

The materials used to transform the aerostat are mainly obsidian and steel, otherwise it would not be called an obsidian aerostat.

Among the materials sent up, there is also a part of mithril alloy, which is used to transform the keel of the aerospace ship.

Since the black technology engine of the Void Spirit family will soon be available, the overall shape of the aerospace ship will undergo major changes and become more suitable for sailing in space.

The original bulky black fish shape is not worthy of a high-end and classy star battleship.

Originally, Zhang Weidao considered that a streamlined shape might be more suitable, and wanted to adopt the shape of a big black fish like a submarine to reduce wind resistance.

But in fact, when the speed of the aerospace ship cannot reach the level of breaking the sound barrier, talking about wind resistance is simply thinking too much.

During World War II, those fighter pilots even opened the windshield of the fighter plane to blow out the wind even though the flying speed was not slow!

These guys dare to drive the fighter plane into a convertible sports car. It can be seen that wind resistance and other things, as long as the speed is not abnormal, will not harm them and the fighter plane.

In fact, it doesn't matter if the aerostat is designed as a pie or even a ball, it will probably still fly very smoothly.

The shape of those UFO flying saucers on the earth is definitely not aerodynamic, and they are not being tested again and again.

What makes the public confused every time is that aliens have come to the earth, but it is actually an aircraft experiment by scientists.

Especially in terms of anti-gravity and hovercraft, wind resistance is not that important.

In front of the strong shells of these powerful aircraft, there really is no big limit to the so-called wind resistance.

No matter how strong the wind resistance in the atmosphere is, it cannot shake the outer shell of the star battleship, which is always made of alloy and needs to cruise around in the cruel universe all year round.

The space shuttles on Earth that return from outer space are violently rubbed by the atmosphere every time, and their armor plates are burned to the point of roasting. They still land successfully, and go back and forth between space and the Earth again and again.

However, the shape of the space shuttle is still relatively conservative, and Zhang Weidao will not make the shape of the battleship too exotic.

Most of the star battleships in science fiction novels are in the shape of long strips, and there is no need to really make them into a sphere or a disk shape.

Star warships that can be spherical or disc-shaped are often the mothership of the star fleet, playing a role similar to an aircraft carrier in naval battles, and can even launch star destroyer cannons to directly destroy planets at the slightest disagreement.

Such a powerful interstellar carrier is not something Zhang Weidao can temporarily include in his plan. It will be a long-term goal that requires the resources of the entire Azeroth to support it.

After all the personnel and materials were in place, the casters gathered together and began to transmit mana through the energy transmission network deployed by Zhang Weidao, preparing to work together to open the obsidian armor of the aerospace ship and adjust and reorganize the external structure.

The material obsidian is indeed quite excellent. With the infusion of mana in place, the armor on both sides began to be decomposed, and it was perfectly integrated into the upper and lower parts of the aerospace ship that were originally relatively flat.

After the outer obsidian armor plate was disassembled and integrated, the inner skeleton-like mithril alloy keel was revealed.

Every ship has a keel. From fishing boats in the sea to aircraft carriers, to airships and planes flying in the sky, and even interstellar battleships in the universe, they all cannot escape this ancient structure.

These keels used to strengthen the structural strength of the ship are actually the same as the load-bearing walls and steel bars of the house. Without the support of these things, cement and bricks alone cannot guarantee the sturdiness of the house.

When the goblin technicians inspected the keels that were changing shape, they just used instruments to roughly measure them, and then went to the next measurement point with satisfaction.

When the caster's mana is extended on an object suitable for guiding magic, they can operate the object down to the molecular level. Even with a humanoid high-precision CNC lathe like the goblin technician, it is difficult to find any problems.

.

The power of spells is so overbearing. In fact, a large part of the core of those cutting-edge robots needs to be built by spellcasters.

Otherwise, with goblin and gnome technology's level of electronic technology at the tube level, they wouldn't even be able to build a mobile phone for the elderly, and at most they would be able to build a radio.

In a world like Azeroth, where technology and magic coexist, in fact, many technologies require the power of magic to maintain, otherwise it would not be able to support those so-called black technologies.

Judging from the transformation of the keel and obsidian armor, the general appearance and structure of the aerospace ship can be judged.

When this floating ship is completed, there will definitely be no arc-shaped shell. Didn't you notice that the keels have been tossed into square shapes by spellcasters and goblin technicians?

However, the cross-section of this aerospace ship should not expand too much, after all, the overall length is there.

If it is too outrageous and the hull becomes a square shape, it will be funny!

The overall length of the aerostat cannot be easily expanded. There are too many lines laid out on the main body by goblin technicians. These complex lines that have been laid out long ago cannot be easily changed.

If you forcibly change the wiring, it is equivalent to reassembling it, and it will take at least a month to fix the complicated wiring.

At this critical time when this powerful aerial battleship is needed everywhere, Zhang Weidao will never accept lying in the aerial battleship dock for a few months.

Just modify the external armor and structure, and make preliminary use of the vacated main space. It can at least become an effective military depot and weapons and equipment warehouse. This is the transformation index that Zhang Weidao needs the aerospace ship to achieve.

Once the aerial ship is transformed and combined with Prince Kael'thas' aerial mage tower, Zhang Weidao will have some confidence to enter the planet Draenor.

Two star battleship-level aerial behemoths are enough to carry the entire expeditionary force, making them unstoppable in both attack and escape.

Only in this way can he have the confidence to cross the Dark Portal and enter Draenor, which may already be occupied by many legion demons.

Seeing that everything was normal on the aerospace ship that was being renovated in full swing, Zhang Weidao took Irene around to visit this very important industry of the pantheon.

The Alterac production base, which integrates production and mineral extraction, now looks like a considerable industrial city.

The merchants from the surrounding kingdoms all rushed to the train to purchase and sell various supplies.

Various weapons and equipment, as small as kitchen knives, iron pots and tableware, as well as various specialties from the fertile wilderness of the west are all treasures that businessmen from all over the world are eager to acquire.

The red molten iron flowing out of the tall giant chimney-like blast furnace is like gold coins in the eyes of businessmen.

Of course, in a certain way, these steels are really the embodiment of gold coins.

Even though the price of steel has been suppressed a lot, this metal, which is in high demand, still has a high value.

Strong scientific and technological productivity has brought strong development momentum, which is incomparable to those backward kingdoms.
