After discovering that it was no longer possible to find out the purpose of the tunnel, Lu Cheng gave up the idea of continuing his exploration and rushed to the Skull Fort with the militia.

Skull Castle as a subordinate area of the sword wielder's territory can not exceed the main area in terms of population and size, because Skull Fort belonged to the bandits' territory before, all of them were robbers and there were no civilians, so the previous Skull Fort city wall was relatively small, and after Jona took charge of the management of Skull Castle, the entire original wall was demolished and re-planned for construction.

The first is to move the entire Skull Castle to the edge of Crescent Bay, the terrain of Crescent Bay is very suitable for defense, and it is very suitable as a shipbuilding base and trading dock, in the future development plan of Skull Castle agreed upon by Leah and Jona, Skull Castle will build large dry docks on both sides of the opening of Crescent Bay, and the place directly opposite the opening will be built into a huge comprehensive dock, and Skull Castle will contain the entire Crescent Bay into the city.

Lu Cheng very much agreed with this plan, but was frightened by the astonishing financial needs calculated by Liya.

The scale of the first phase of the dry dock on both sides is 200×60 meters, each of which is 4 times the size of the sword-wielding dry dock, and unlike the sword-wielding waterwheel power, the skeleton fortress needs a new power source in drainage because there is no large river nearby, and Leah and Jona decided to use wind power after fully investigating the environment of the skeleton castle.

As a result, each dry dock requires the construction of 10 wind towers with blades up to 15 meters long, which were converted from the wind mill drawings acquired by Lu Cheng. However, the original wind mill was only 7 meters per fan blade, and the wind tower directly doubled to 15 meters, and the cost was also terrifying.

As for the cost, the price of each dry dock was as impressive as his configuration: 200,000 gold coins.

As for the dock area, the 30 large piers lined up along the coastline almost fill the coastline, and of course only 5 of them will be built in the first phase of development, but even so, the total cost of the 5 completely renovated large piers is more than 100,000 gold coins.

The construction of the city wall and the production and living facilities in the city are also configured in the direction of luxury.

In Leah's words, this is a city paved with gold coins.

Lu Cheng was very happy to reward her with a brain.

In terms of burning money, ten Lu Cheng couldn't catch up with Liya, but Lu Cheng finally gritted his teeth and agreed to Liya's idea, one is that the dry dock of the sword bearer has been operating normally, and the efficiency of producing 3 Galen-class warships and 7 primary ordinary transport ships at the same time is many times higher than that of ordinary docks at a time, and the initial construction is expensive, but as long as the ship can be sold, it won't take too long to earn back the money invested.

Second, the geographical location of Skull Fort is relatively good, the topography of Crescent Bay is very conducive to the development of shipping, and the narrow entrance and wide water surface inside are also a good haven, which is much superior to the Sword Bearer base. Moreover, in the future, as long as the shore defense artillery is arranged on both sides of the Crescent Bay, the defensive force will also be very strong. Under Lu Cheng's vision, Skull Fort will become a future naval shipbuilding base and a major naval port.

Third, the sword-wielding base is closer to the kobold forces in the west, the player and the Kandi Kingdom, and in the event of a war in the future, the skull fort to the east of the sword-wielding base will become the most favorable strategic support for the main base, expanding the strategic space.

In addition, the cost of terrorist development is not the only obstacle at present, and the biggest difficulty at this stage is to increase the population.

Lu Cheng was still a short distance away from the Skull Castle when he met Jona, who was inspecting the work.

"My lord, why are you here?" Qiao Na was extremely surprised when she saw Lu Cheng.

Lu Cheng said with a smile: "Come and see our hard-working Miss Jona, what are you doing here?" ”

At this moment, there are more than 100 citizens around Jona, who are busy with something.

"I was going to tell you the good news the next time I saw you." Jona pointed to the citizens who were busy next to her, "A few days ago, we found a copper mine in this place, because the construction of the territory needs copper mines, so we arranged for people to come and mine, and when we brought the collected copper ore back to be smelted, we unexpectedly found that for every 100 units of copper ingots extracted, we could get 0.5 units of gold. ”

"Is this a copper-gold mixture?" Lu Cheng asked in surprise.

Jona grinned and nodded, "Yes." ”

Gold and gold coins are not 1 unit for 1 gold coin, in fact, the value of each unit of gold has not been accurately defined for the time being, but according to some players on the world information, 1 unit of gold can be sold for more than 200 gold coins in the ports of some NPCs.

"Have you estimated the reserves of this mine? How much does it produce per day? Lu Cheng asked eagerly.

"There are 3,000 groups of estimated copper ore reserves, and 15 groups of gold mines are calculated according to the proportion, and I have arranged 150 citizens to mine them, and they can collect 150 groups of copper ore and 75 units of gold ore every day." Jona said.

Lu Cheng quickly calculated that 75 units of gold ore were worth 15,000 gold coins based on 200 gold coins per unit! The entire reserve is worth 300,000 gold coins!

It's a cornucopia!

"Yes, this mine will be a huge help in the construction of Skull Fort." Lu Cheng affirmed, "Jona, all the gold produced will be sent to the sword wielding base, and I will sell the gold and exchange it for gold coins to develop Skull Castle for you." ”

Qiao Na was overjoyed, she didn't expect Lu Cheng to not take even a single unit of gold and give all the income to her for the construction of Skull Castle.

"My lord, how about I show you around our new Skull Castle?" Jona said happily.

"It's an honor!"

In fact, the new skull fortress that Lu Cheng saw had not even been built yet, but from a distance, all kinds of buildings had been built along Crescent Bay, and the core administrative hall (also known as the council hall) was next door to the dock area, and Qiao Na obviously adopted the management model of NPC, all agriculture and animal husbandry were arranged outside the planned city wall, so the number of habitable people in the city was many times higher than that of the sword wielder's territory, and Lu Cheng felt that after returning home, he also needed to learn NPC to gradually transfer agriculture and animal husbandry outside the city.

"At present, there are 3,000 citizens in Skull Castle, and hundreds of new citizens will join every day, and it is expected to reach the upper limit of 6,000 population soon, because it was taken from the robbers and then demolished and rebuilt, so the prosperity needs to be recalculated after zero, and it is expected that it will be successfully upgraded to a level 1 village in about a week."

Jona led Lu Cheng all the way through the streets.

"Miss Lia gave me some ideas for urban planning, I think Skull Fort should be positioned as a ship production base and a maritime trade center city, so I have a functional division of the city, you see, the east of the administration hall is Crescent Bay, the administration hall is divided into 4 areas as the center of the circle, the area from the north of Crescent Bay to the north of the administration hall is the commercial area, and the area from the south of the crescent bay to the south of the administration hall is the military construction area, and all military facilities will be set up in this area. In the middle of these two areas, because of the existence of Crescent Bay, the area is the smallest. The other 2 areas will then become residential areas. ”

Jona said, pointing to the continuous construction site.

Lu Cheng could only keep nodding, Leah and Jona's urban planning made him very satisfied, although the sword holder's territory was built neatly, but many places he did not carry out functional planning, and they were just filled in if there were holes.

"My lord, do you have any instructions?" Jona asked cautiously after the basic introduction.

Lu Cheng pinched his nose, to be honest, he didn't pay much attention to Skull Castle, and he was far from expecting that Qiao Na would be able to build this place so well, so if he wanted to talk about instructions, he could only encourage and encourage him to make new requirements by the way.

"I am generally very satisfied with the construction of the new Skull Castle, but one thing I hope you can improve, the construction of the city wall must be accelerated, and the current surrounding situation You also know that the Skull Fort is still in an undefended state, which is more dangerous."

Qiao Na's face was slightly red: "Follow the instructions of the adults, I will arrange the construction of the city wall immediately." ”

Lu Cheng nodded: "Is there anything you need my help with?" ”

Jona is not pretentious: "Thank you, first of all, in terms of funds, the start-up capital of 20,000 gold coins for the development of Skull Castle has been basically used up, and before starting a big project, it is necessary to invest another 50,000 gold coins, and once the construction of the dock and dock starts, the gap in funds and talents will be very significant." ”

"This time I came here to prepare for a new investment fund." Lu Cheng already knew that the funds were still not enough before he came to inspect, "Here are 50,000 gold coins, if it is not enough, send someone to me to get it." ”

Jona: "Thank you, my lord, I will make Skull Castle a powerful city." ”

Lu Cheng said: "The exploration of the sea area in the east should also be arranged immediately after the dock is built, and we must know the situation in the east in order to better develop the skull fort." ”

"Follow your instructions."

Lu Cheng looked around with Qiao Na again, with the pace of construction and development, the number of citizens is also increasing, and a new citizen will be refreshed at the door of the administrative hall almost every few minutes, and occasionally you can see the colored light pillars of skilled citizens.

"My lord, at present, Skull Castle has recruited 19 junior professions, 3 intermediate professions, and there are no advanced professions for the time being." "And when you're building a big project, it's going to be very difficult without a corresponding senior professional." ”

Lu Cheng: "Well, when the time comes, I will send someone from the sword wielder's territory to assist, don't worry." ”

After chatting for a while, Lu Cheng summoned Arthur and Gru to learn about the defense situation, the initial 200 militia has expanded to more than 300, and the weapons and equipment cannot be self-made for the time being, all of them need to be transported from the territory of the sword wielder.

After encouraging everyone, Lu Cheng returned to the territory of the sword-wielder, and then he had to wait for the Calais-class battleship to go to the surrounding waters to investigate the situation.
