Chapter 237: Large Weapon—Crystal Cannon!

The rest of the day passed in the forest near Iron Skull City. He was still short of 10 million experience points to level up Aisha.

Unfortunately, the monsters around were relatively low in level, and he did not find enough monster maps, causing him to only obtain 2 million experience points per day.

The next day, Lorne put away his short staff and used the magic circle of Iron Skull City to return to the Gnome Mineral Company.

“Mr. Tyrant, the Purification Crystal you need has been refined.”

Tully led Lorne to a warehouse. There was an altar built with special ores. On the rocks were countless runes that formed a special magic circle. All the energy was gathered in the center.

Above the center point, a huge Dragon Crystal floated. It emitted a dazzling light, like a high-powered light bulb.

“This is the Purification Crystal you want.”

Tully explained, “This huge energy magic circle will transmit the purification power to the gem at the top. Then, the gem will radiate light and cleanse the surroundings. An ordinary Purification magic circle can be refined with only an ordinary crystal. However, the range you want to cover is too large, so you have to use the dragon crystal as the main body to withstand the energy. Only then can you purify the huge range of 100,000 hectares.”

“So big…”

Lorne did not expect that the so-called Purification Crystal was not only a crystal, but the magic circle at the bottom. Only by combining the two could the effect of regional purification be displayed.

“Mr. Tyrant, you can install this Purification Crystal in the center of the city. When you drive it with all your might, the Dragon Crystal will fly into the sky like a round moon, illuminating the surrounding darkness. Its light is very gentle and beautiful. It might be a large landmark in the city.”

Tully smiled and introduced it to Lorne. It could be seen that he was also proud of his results. After all, in the history of the Gnome Mineral Company, there had been few cases of using the Dragon Crystal to refine the Purification Crystal. This was an extremely great honor for him.

“Yes, that’s my plan.”

Lorne stepped forward and used the Dragon’s Treasure Vault to collect the huge Purification Crystals. Then, he looked at Tully and said, “We’re about to leave. Are you ready?”

“Everything’s ready.” Tully said, “There are a total of 1,000 technicians, 5,000 construction workers, and 4,000 manufacturing workers who followed me this time. There are exactly 10,000 people. I wonder if we can arrange for so many people to stay in Mr. Tyrant’s territory?”

“Of course, it’s not a problem. The gnomes who have joined the territory will receive the best treatment and will give you the most dreamlike research area and projects. I promise you in the name of the City Lord.”

Lorne gave the other party a confident answer. In his eyes, the technology of the gnomes could benefit the people. Even if it could not extend into their lives, they could still move towards the armed main city. Therefore, Lorne would give them the best treatment. This was definitely not empty talk.

Tully was grateful for this answer, and he led Lorne to the landing site.

The gnome airship was ready. Due to the large number of people, many airships were chosen to transport it this time. However, because the airship was specially transported this time, its armed strength was relatively poor, so there were still a few offensive airships escorting it.

Lorne was interested in the weapons on the offensive airships.

On those offensive airships, there were several cannons and a large crystal tower. What was their specific use?

“That’s a crystal cannon.”

“Under normal circumstances, such large crystal cannons are installed on the city wall. Because the magic circle engraved is very large, it’s difficult to move around. However, in order to let the airship equip a cannon, our gnomes have specially studied the miniature crystal cannon. This magic cannon can be installed in the small space of the airship and use the high mobility of the airship to suddenly attack the target!”

“But of course, while undergoing special optimization, some performance will naturally be sacrificed, such as power and energy conversion efficiency.”

“Under normal circumstances, the crystal cannons of the city defense need 100 units of magic energy each time, but the cannons on these airships need 200 units. Their energy conversion is relatively poor, so each attack will consume twice the energy and unleash 40% less power.”

“Fortunately, mobility is their greatest value, making them our most important defense weapon.”

Noticing that Lorne was interested in the magic cannons, Tully explained in detail.

Then, he pointed at the tower and said, “That is a crystal energy protective device. It was specially created to protect the airship from the attacks of long-range artillery. Because it occupies a huge space, only the offensive airships are equipped with a protective device. Ordinary transport airships do not have such defense methods.”

These were all good stuff…

Lorne looked at the equipment on the offensive airships and could not help but sigh. In this magic world that worshiped personal strength, the gnomes had actually created a “fighter jet”. Cold Desolate Dragon City had to have such advanced technology!

“Tully, how many gold coins do you need to build a crystal cannon for the city defense?” Lorne could not help but ask.

“Er, if we only use gold coins, we can’t build any crystal cannon.”

“To build a conventional crystal cannon, you need 47 materials, 25 of which can’t be bought with gold coins. For example, the most basic Star Patterned Iron can only be bought by going to a main city with rich minerals. Moreover, you need to obtain the other party’s permit. You can also buy it in the Gnome Mineral Company, but unless the two sides are close enough or if there’s a chance, under normal circumstances, they will not be sold.”

Tully did not want to discourage him, but it was inevitable.

However, Lorne did not think much of it. Instead, he asked, “Do you have anyone who can create such weapons?”

“Yes. To be honest, I started my career by building crystal cannons. Later, for some reason, I transferred to building design. If you only want the crystal cannons and have enough materials, I can quickly let you develop your own city defense weapon.” Tully was also very excited. After all, building cannons had always been his dream.

“Let’s wait first. During this period of time, you guys have to first reconstruct the main city, and I’ll think of a way to gather the materials to build the cannons.”

“Yes, Mr. Tyrant, let’s go now.”

“Yes, let’s go!”
