The core crystal of Castlevania, located beneath a statue of the Virgin Mary in the center of the dungeon.

When Locke came to the statue and looked up, information about the statue came into his mind:

The former lord, Ms. Isabel, is a benevolent vampire, and this statue of the Virgin was built by her, and the core crystal can reach its current scale, which is naturally due to her credit, but also because of her kindness, it directly led to the fall of the previous generation of Demon King City.

Locke stood there and looked up for a long time, next to him, little Annie, who was wearing a maid's costume and biting her fingers, while holding Locke's hand, looked at him strangely, and didn't dare to disturb him.

For a long time, Locke, who had been staring at the statue, sighed faintly:

"Dear Lady Isabel, you are worthy of boasting for your contribution to the castle, but as a member of the Dark Clan, your kindness almost brought our people to a point of no return, but in the end you interpreted everything with your own life. As a successor, I would like to sincerely wish you all the best in the other world. ”

After speaking, Locke bowed deeply to the stone statue, and Anne next to her quickly bowed when she saw it, although she didn't understand it very well.

After Locke finished saluting, he directly stepped forward and pressed the mechanism under the statue, and suddenly a secret door appeared in front of him.

Inside, through a long, narrow and dimly lit rock passage, you finally come to a huge karst cave filled with blue light.

Locke took Anne's small hand and walked down the stairs made of rock, slowly walking towards the towering core crystal in front of him.

The giant crystal that glows blue is diamond-shaped and 10 meters high, about the height of a three-story building.

There are other smaller crystals floating around the core, each of which corresponds to a related facility in the castle, and there are only a few of them at present, which means that there are quite few buildings in the city that can be powered by crystals.

Not far from the core, there are piles of building materials and magic crystals stolen from the bandits, which will be used later, and if the buildings in the city are damaged, the building materials here will be consumed in advance to repair the cracks.

Looking at the giant crystal in front of her, Anne let go of Locke's hand, flapped her wings, flew into the air, turned her head and asked, "Are you ready?" The expression looked extremely solemn.

Under Locke's nod, her figure quickly shrank back to the shape of an elf, and her body also sank into the core crystal, and after a while, the light brightened.

When Locke came back to his senses, he seemed to be floating in the air, and a panoramic image of the entire castle was displayed below.

"Please tell me what you want to build, where you want to build, where you want to build, how much space you want to build, and how much energy you want to consume." Annie's voice echoed all around, but it sounded very cold, like an emotionless machine.

This may be how the core system works.

Locke stood in the void, scanning back and forth at the buildings below, and finally reached out and pointed at one of them and said, "There it is." ”

The image zooms in instantly, and the address is located on a small corner to the west of the city.

"What do you want to build?"

"Graveyard of Terror, Screaming House, Forge, Alarm System, Elf Assist System."

"The size of the first three facilities?"

"A standard second-order building that leaves room for sustainable upgrades."

"Interior space?

"General."

"Base energy loss?"

Hearing this, Locke paused, the greater the energy provided to the facility, the higher the output in it, but the total amount of the castle will be reduced accordingly, so the reported energy should not be too large, but if it is too little, the output will be less.

This is a great loss in wartime!

"2,000 square meters per facility." That is, the two points of energy that Locke converted in his heart before.

"It may take half a day to receive your order, please be patient."

As the sound fell, a large amount of building materials were sucked into the crystal, and then all of them poured into the location of the Graveyard of Horrors and began to build automatically, as for the alarm system and the elf assistance system, it was given away for free, because their consumption did not cost much energy.

"Do you have any other questions?"

Locke looked at the image of the castle below, and when he heard the voice, he looked up at the pitch-black sky, and said, "Can you upgrade the crystal now?" ”

"The criteria for promotion have been met."

"Then do it."

"Yes."

With Locke's order, the entire castle began to shake to the ground, and the buildings in the middle of the city began to rise and expand like trees at a speed visible to the naked eye, as did the outer city walls.

Locke stretched out his hand and flicked the image, and the scene instantly switched to the interior of the castle, all the rooms stretched quickly to the sides like rubbers, and the decorations inside, such as crystal lamps and vases, were not affected in the slightest.

After a few seconds, a brand new castle that had doubled in size, with a large number of black flags flying on the top of the clock tower, appeared in front of him, and a patch of arrow battlements appeared on the edge of the surrounding city walls, and the whole castle was completely renovated inside and out, completely devoid of the dilapidated appearance of the previous low-level level.

The second-order castle has begun to take on the shadow of a quasi-military fortress castle.

Looking at the city under his feet, which was larger and grander than before, Locke couldn't help but sigh in his heart, and at the same time, the cold system voice of the core crystal sounded again:

"At present, there are 210,000 square meters of Dimon Cuin, and it will take 800,000 square meters to enter the next level."

This translates to 210/800 energy reserves.

"Is there anything else you need?"

Locke shook his head and smiled and said, "Thank you." ”

"Will serve you, my noble king."

After speaking, the surrounding space returned to its original state, and Locke looked around, it was still the karst cave, or the ten-meter-high giant crystal pedestal, but the building materials and magic energy crystals in the distance behind him were mostly missing.

It seems that I still have to worry about future resources.

Forget it, just count it as the overall goal, life in the world, isn't it just to run around for all kinds of resources?

"The host ~~~"

Little Annie's cheerful figure burst out of the crystal, then quickly expanded into the shape of a child, and threw herself into Locke's arms.

"How? Did it work? Anne asked excitedly, looking up at Locke.

She enters the crystal unconsciously, just like when she writes the fairy diary, all under the control of the building in question.

Locke looked at her and smiled and nodded, then looked up at the crystal, where the three crystals representing the Graveyard of Terror, the Screaming House, and the Forge slowly formed, and finally floated around the main crystal like stars, moving slowly around it.

"Let's go and see what we did together." (To be continued)
