From a distance, this castle is at least twenty meters high, but it is not made of bricks and tiles, but is made entirely of black and silver metal, giving it a mechanical feel.

Its exterior is extremely exquisite, and the inside and outside are closely arranged together, making full use of the space, but giving people a very grand feeling.

Black metal is used as the main material of the castle, and silver metal is used as the skin to cover it. In addition to blocking the scorching sun outside, it can also absorb solar energy and convert it into the power source of the entire mechanical castle.

Two crawlers appeared strangely below the castle. Each crawler track was more than a hundred meters long, and the crawler chassis was four to five meters high, occupying a quarter of the height of the castle.

It is these two tracks that move the entire giant castle.

This movable castle is like a giant tank, racing arrogantly in the sea of ​​sand, careless and ignoring everything.

Although the mechanical castle is huge, it runs extremely fast, no slower than a real tank.

And whether it is a tunnel in the desert or a terrain on a slope, the speed of the mechanical castle is not affected at all, just like walking on flat ground.

The mechanical castle kicked up a lot of sand and dust, and behind it a group of armored lizards with a size of seven to eight meters were chasing the crawler castle, like unyielding enemies.

They originally had no grudges against this mechanical castle, but this thing inexplicably crushed several of their clansmen to death.

This group of armored lizards were extremely vengeful, and they chased after them while manipulating the sand in the desert to attack the castle.

Although they knew a little earth magic, before the sand fell on the mechanical castle, a silver light bloomed and blocked all the sand.

The sand in the sky could only slide down the smooth wall of the mechanical castle, and fell into the sea of ​​sand again.

Later, the mechanical castle seemed impatient to be attacked. Suddenly it turned around and the huge tracks rolled over, instantly crushing the large armored lizards into meat pies. The panicked group of iron-headed lizards immediately fled in all directions.

.

In the main hall on the highest floor of the Mechanical Castle, Wang Zhan was standing in front of a transparent glass, looking at the endless sea of ​​sand in the distance.

Behind him, a group of goblin alchemists are constantly busy recording various data of the mechanical castle.

"It's really ugly."

Wang Zhan sighed. He originally wanted to build a floating city, but unexpectedly he built a large tank.

The current mechanical castle cannot fly in the sky, nor can it run if it is equipped with legs. It can only be driven by these crawlers to run.

"Craig, how long will it take for the power issue to be resolved?"

Craigie was the gnome who had no mental power and was unable to become an alchemist, but he made a hot air balloon.

After Chen Luo let him awaken his spiritual power, Craigie grew step by step with his extraordinary mechanical talent, and now he has become a sixth-level alchemist. He is also relied upon by Wang Zhan and becomes his core team.

"Your Majesty, the size of the floating city is too large. The power we can create now can only make it rise to a few tens of meters at most before it can no longer support its continued flight."

"This is not even as good as an alchemy airship. What's the use of coming here?"

Wang Zhan frowned, the floating city has extremely strong strategic significance.

If this thing could be manufactured, it would allow the goblins to gain air supremacy in the Western fantasy world.

The floating city is different from the alchemy airship. It can carry a large number of alchemy weapons, and its sturdiness is unmatched by ordinary war airships.

Taking height as an example, in Wang Zhan's vision, the floating city can fly to an altitude of nearly 10,000 meters.

Even extraordinary beings above the holy realm cannot continue to fly in a state of lack of oxygen.

And even if they can fly up, the alchemy cannon on the floating city is enough to resist threats from any direction.

Nowadays, the goblins' alchemy cannons exceed those of other races in terms of power and range. They can completely use the floating city to fly to a range that other races' alchemy cannons cannot attack and achieve artillery coverage.

But the trouble now is that there is insufficient power to maintain the floating city flying for a long time, let alone permanently floating.

"Your Majesty, the main issue is the conversion efficiency. Although the sun's energy is endless, the conversion efficiency through solar panels is too low, making it difficult to maintain a long-term flight."

"Then use the alchemy array to absorb magic energy and increase power!"

Craigie was stunned for a moment, "Your Majesty, although the alchemy array can absorb and convert energy, its duration is also limited and does not meet the conditions for being permanently empty."

Wang Zhan said calmly, "Since we don't have the conditions to leave it empty permanently, we just need to let it fly now."

Craigie's expression changed slightly. He was also a smart man and he immediately understood what Wang Zhan meant.

During this period, the Buya Empire was undercurrents, and it would be no exaggeration to describe it as wave-yun and treacherous.

But Wang Zhan knew this, but he didn't take any action. He just concentrated on studying the alchemical machinery that converts solar energy into power.

Wang Zhan named it "perpetual motion machine". Although it can only absorb solar energy at present, the ultimate goal of the perpetual motion machine is to absorb any energy and convert it into power, such as wind energy, tidal energy, thermal energy, etc.

Wang Zhan can't wait for the perpetual motion machine to be fully developed, but wants to use this flying floating city to once again improve his prestige.

As long as this floating city flies to Lophes City, it will temporarily suppress the secret actions of the sages and great nobles.

Although it is only temporary, those people will definitely continue to make small moves secretly in the future, but this is all Wang Zhan needs.

Because Wang Zhan only needs to return to Lophes City to immediately build his faith in the God of Alchemy.

As long as you gain the power of faith and ascend to the throne of God, those people will be as fearless as clowns.

"But Your Majesty, those sages will definitely find a way to ask for inspection of the floating city..."

"Hmph, can they inspect my things if they want?"

Wang Zhan sneered, waved his hand to interrupt what Craigie wanted to say, and decisively ordered, "Take off directly."

Craigie hesitated to speak, but when he saw Wang Zhan's appearance, he knew that it was useless to say anything.

He had no choice but to bow and salute, "As you wish, Your Majesty."

The mechanical castle now penetrated the edge of the desert and stopped at a huge ridge. The exposed ridge showed pure black and stretched to the sky.
