[Capacity: The size of the space will increase as the castle level increases]

[Supplies: more than 130,000 units of food, more than 2,730,000 units of wood, more than 2,800,000 units of stone, more than 1,040,000 units of refined iron, some monster materials, some gold coins, gold and silver utensils, gems, and noble ornaments]

[Current status: Invincible]

[Special reminder: If the heart of the castle is destroyed, the warehouse's dimensional space will collapse, and all the stored materials will fall and become spoils of war for the hostile forces.]

【Protect the heart of your castle!】

“That’s enough!”

Tang Xiaofan looked at the amount of supplies stored in the castle warehouse with a smile on his face.

Tens of thousands of pieces of equipment and thousands of high-level equipment, including dozens of level 20 equipment, are for sale or auctioned.

All were sold out overnight.

The total harvested wood and stone exceeded three million units.

With his existing supplies,

He now has a total of more than 2.73 million units of wood and more than 1.8 million units of stone.

Another overnight fortune! The most important thing is,

After just one night, his castle could be upgraded again.

"Attacking the kingdom's forces is really a great way to make money!"

Tang Xiaofan couldn't help but sigh at the wealth of the kingdom. The sale of equipment this time, plus the supplies previously seized directly from the Goblin Kingdom, the total amount of supplies harvested exceeded 10 million units.

He gained so many resources from just one goblin kingdom.

How could it not be rich? At least, compared to those large, medium and small local forces, the Goblin Kingdom is truly rich.

"Upgrade the Black Tech Castle from an advanced town to a primary main city,"

"It will take two million units of wood, one million units of stone, and five hundred thousand units of refined iron!"

"My current resource reserves are more than enough!"

Tang Xiaofan did not hesitate and immediately opened the castle's upgrade information prompt.

[Whether to upgrade the castle]

"yes!"

As soon as Tang Xiaofan finished speaking, a dazzling golden light instantly appeared, covering the nearly 100-meter-high black technology castle.

Then the golden light began to spread, quickly covering the buildings inside the castle and the castle's entire direct territory.

soon,

The entire black technology castle was completely shrouded in golden light.

Tang Xiaofan was very familiar with this upgrade process, as he had experienced it many times.

However, Tang Xiaofan could still feel that the difference from the past was that the changes in the upgraded castle this time were even more drastic.

His castle was growing wildly, and the castle's direct territory was also expanding wildly.

Even the city wall he had just built yesterday was madly getting wider and taller! The sudden change in the city wall was something Tang Xiaofan had not expected, because the castle had been upgraded many times before and the wall had never changed.

But this time with the upgrade, the city wall, a defensive building that is a higher level than the wall, has changed.

Tang Xiaofan guessed that this should be related to the upgrade of the black technology castle to a primary main city.

After all, after this upgrade is completed,

His castle was no longer a town, but a real city! Time passed slowly, and when the upgrade of the Black Technology Castle was not yet completed, about a hundred kilometers away from the Black Technology Castle, there was a human figure, but the strange thing was that the figure's head was the head of a dragon.

That is, a human body with a dragon head.

It stands on the top of the mountain like a human, with its hands behind its back and its golden vertical pupils looking in the direction of the black technology castle.

Even though it is more than a hundred kilometers away, it can still see the dazzling golden light.

“Another upgrade!”

The monster with a human body and a dragon head spoke human language.

His tone was dull and solemn, and he looked very upset.

The powerful Dragon's Nest suppressed the entire forest. Which local forces dared to disobey? Even the kingdom forces trembled under the deterrence of the Dragon's Nest Dragon Legion.

But suddenly, a large number of castle owners from another world appeared in the forest.

Among these castle lords, there appeared another super perverted guy.

Not only did he conquer the elf tribe, but he also captured the goblin kingdom hidden in the underground world.

What Dragon Nest feared the most was that a demigod-level strongman had appeared in this castle force! Olivia, the former spirit of the elven mother tree of the elven tribe, broke through the peak of level 21 and was promoted to the demigod realm not long after she joined the castle force.

This is what Dragon Nest fears the most, "The power of this castle is growing too fast!"

"If we leave it alone, the Dragon's Nest will be conquered by the castle lord sooner or later!"

"But if war breaks out,"

"Many dragons will die at the hands of Olivia. After all, the power of a demigod cannot be underestimated!"

“My head hurts!”

“Just hope everything goes well this time!”

The voice fell,

A figure emerged from the monster with a human body and a dragon head.

This figure looks almost exactly like it, as if it is a replica of it.

This is its energy consciousness body! It is condensed from pure energy and controlled by spiritual consciousness.

Then, its energy consciousness body flew high into the sky and flew straight towards the black technology castle more than a hundred kilometers away.

It was obviously afraid that its main body would go over and be killed by the owner of the black technology castle, so it mobilized the energy consciousness body.

Because even if the energy consciousness body is blown up, it will at most lose a little energy and mental consciousness, and it will be able to recover after resting for a day or two, so there is no need to worry about encountering danger.

However, how could it know?

Its figure had long been discovered by the Skyless City, located hundreds of thousands of meters above the sky.

As the Sky City absorbs energy and operates normally, its functions become stronger, and the area that its core divine pattern can monitor is getting larger and larger.

Sky City has no interest in life forms at level 20 or below.

Because it is too weak! The core divine pattern of the Sky City cannot sense such subtle energy fluctuations.

The lowest level is twenty-one.

Before the Great Elf Monica joined Tang Xiaofan, she approached the Black Technology Castle alone and was discovered by the Sky City on the spot. Then Tang Xiaofan activated the Terminator without saying a word and locked the Great Elf Monica.

Now, the same is true for this monster with a human body and a dragon head, and its level is also twenty-one.

It has reached the minimum monitoring standard of the Sky City, so as soon as it appears, it is monitored by the core divine pattern.

Both its main body and its energy consciousness were tightly controlled. Tang Xiaofan only needed one command. It thought it was more than a hundred kilometers away from the black technology castle.

It is very safe to hide its true body and send out its energy consciousness. In fact, it is only one step away from death.

Black technology castle,

Tang Xiaofan also received a warning from the Sky City.

In addition, Jarvis also projected the figure of the invader discovered by the core divine pattern of the Sky City in front of him.

Coupled with the drone's surveillance and reconnaissance, the intruder has almost nowhere to hide.

Let's not talk about this.

Just to say that when Tang Xiaofan saw that figure, he was still shocked.

A human body, a dragon's head.
