The System to Become a Dragon

Building a Demon King Castle

Bloody Giant Wang Shi: "Sister, don't say such a thing. Dark gems are rare gems. They are much rarer than the four ordinary elements."

"How about.. 1500. Call this price a friend!"

Zhang Yi: "800!"

Bloody Giant Wang Shi: "1200. I can't go lower. I almost lost my life chasing this gem."

Zhang Yi ignored him.

He decided to leave the other side to hang out for a while.

As expected, Bloody Giant Wang Shi could not last long.

After a few minutes, he finally gave up.

"1000 gold then, alright!"

"800!"

Bloody Giant Wang Shi, upon seeing Zhang Yi so unmoved, could only agree: "Alright, alright. Agree. Call it the price of friends. Please take care of me in the future, man!"

Wang Shi was actually not wrong.

Dark gems are very rare.

However, such gems are not widely used in the current period, while gold is a resource with many uses. Thus, Zhang Yi was confident that the other party would agree to the deal.

He did not lose this deal at all.

Even if Zhang Yi stored the gem without using it, the price would definitely go up many times over in the future if he kept it for sale later.

However, there is no need for that.

Zhang Yi spent more money and bought 100 iron, at the price of 2 gold per iron. As for wood and stone, that he had plenty in his territory.

After collecting everything, he built a castle.

The Demon King Castle was different from other buildings because its location remained.

As the core building of the territory, it could only be built on top of the Demon King Altar.

After a few shocks, an enormous pitch-black castle rose up from the ground.

The castle was built in a gothic style, giving the impression of obsidian. It was not very large, but it was still more than enough to accommodate several thousand people inside.

[Demon King Castle]. All production in region +25%. Within a radius of 1000 meters, all units of the region obtain +30% for all statistics. When the Demon King is inside the Castle, recovery speed is +100%, all stats are +50%.

As expected of the core building.

This effect is very strong.

Just a 25% increase for all production is something that generates immense value.

After the Demon King Castle was created, all the units, be they skeletal warriors, goblins, or draconians, felt an explosion of energy within them. Their movement speed, stamina, and energy were all strengthened.

The Demon King's castle affected everything within a thousand meters.

Thus, it could cover most of the Valley of Darkness.

This is basically the equivalent of a permanent buff to almost the entire region.

Not only did it increase the productivity of the entire region, but it also strengthened the region and the army. The increase it gives is very visible.

The Demon King himself was also much stronger while inside the Castle.

Thus, it was easy to imagine how difficult the Heroes tried to challenge the Demon King inside the Castle.

Plus, the Demon King Castle was a powerful fortress by itself.

The entire castle is designed with three layers. There was only one entry and exit path for each layer as well, so it was very easy to set up guards and defenses. Finally, the Altar is installed in the deepest location.

In this situation, it would definitely not be easy for any Hero to sneak in and try to destroy the Altar.

You could say, with this castle, life will be more comfortable and the region becomes safer.

Zhang Yi could also be more relaxed.

Although the cost to build the Castle was not cheap, the cost was very small compared to the full repairs it brought to the region, making it worth it!

Moreover, food had only become a rare item for the time being.

Zhang Yi checked the trading menu again.

The second round of giga potatoes had all sold out right now.

Zhang Yi was in no hurry to supply the market. Commodities are more expensive if they are scarce. If he continued to add more to the market, it might instead cause the other Demon Lords to refrain from buying so eagerly, thus increasing the transaction fees.

Moreover, Zhang Yi also did not have that many potatoes left.

The cost of maintaining its territory is also not arguably small.

Moreover, Zhang Yi also had no way to replant the potato giga directly for the new harvest.

Therefore, he had no choice but to figure out a way to buy more seeds himself.

He contacted the person concerned.

Zhang Yi: "Are you there?"

Fey Chen Guoguo Flowers: "Yes! I'm here boss!"

Zhang Yi: "i want the seed of 10,000 giga potatoes!"

Fey Chen Guoguo Flowers: "..."

Zhang Yi: "Do you not have it?"

Fey Chen Guoguo Flowers: "Yes, I have. However, it's too much, so I need time to prepare it!"

Zhang Yi: "How long?"

Fey Chen Guoguo flowers: "i will hand over 3,000 seeds now. I will send the rest in three days."

Zhang Yi: "Good!"

Fey Chen Guoguo Flowers: "Do you have any other seeds that you are interested in? I have a pretty good herbal seed here!"

Zhang Yi thought about it a little.

Although this flower fairy seemed to have the ability to grow more seeds quickly, her ability also clearly had its limits. He also happened to have a part of the Spirit Field that was still neglected, so he might as well plant some other items.

Zhang Yi looked at the catalogue and selected two types of herb seeds from it.

The first is a living herb, with a normal growth time of one and a half years. This herb can heal wounds quickly, and its HP recovery effect is powerful.

The second is moonlight ginseng, with a normal growth time of two years. This kind of potion could recover MP and stamina quickly, so it was an absolute necessity for battle and production.

After a bit of bargaining, Zhang Yi bought a thousand live herb seeds at the price of 2 seeds per gold. Then he bought 500 moonlight ginseng at a price of 1 per gold.

The more food and medicine, the better.

Zhang Yi basically monopolized the entire production of Fey Chen Guoguo Flowers.

He could obtain several thousand gold from Zhang Yi just through the sale of seeds.

This undoubtedly made him one of the richest Demon Lords during the current period.

Fey Chen Guoguo's flowers were shocked and overjoyed.

He had decided to cling to this super power. Then, in order to fulfill this whiz request, he immediately summoned more lower flower elves to plant more seeds and exert all his efforts to become the other party's chosen merchant.

Now that the seeds are treated, new problems arise.

There are not enough farm workers.

Zhang Yi only had around 100 goblins. Given the high harvest speed of Spirit Fields, they were only able to plant around 10 to 20 fields. They just don't have enough numbers to support more.

At that moment, a ruthless soldier ran to report.

"Sir. The two runaway goblins have returned."

Zhang Yi did not understand what happened, "They fled, but now they are back? What the hell is going on here?"
