Train Survival: You're really trying to survive!

A massive amount of metal materials were delivered to Zurich through trade.

"The bats are hunting them down. It'll take a while."

Zuli unfolded a huge sheet of paper in the room. "Let's get the design drawings done first."

Zuli quickly sketched the outline of the metal detector on the drawing paper, while also marking various dimensions.

Ivan watched his brother-in-law draw up the plans, occasionally discussing the design with Su Li.

Ivan is a blacksmith, skilled at forging equipment, but he is not as good as Zuli at designing such ingenious tools.

By the time the blueprints were finalized, the bats weren't ready yet. Fortunately, the samples had already been sent over.

Su Li took out the sample and examined it.

【Overtone Crystallization】

[A certain naturally occurring mineral has an amplifying and focusing effect on multiple waveforms of energy, especially sound waves, with excellent results.]

Su Li played with the crystal in her hand and asked Sun Keke, who had just returned, "Do you think it can be processed?"

Sun Keke is a skilled craftsman, and she is particularly adept at processing various gemstones.

Sun Keke lost her eyes, but she can gain another kind of vision through magic.

She took the gemstone, twirled it in her hand, and examined it carefully through her elemental vision and tactile sense. After that, she nodded. "It has unique properties, its grade isn't very high, but it's easy to process. What kind of gemstone do you need?"

Su Li began to describe her needs, "The cursed sand outside, combined with its granular structure, is essentially equipped with a certain level of magic resistance and detection resistance. Therefore, we need to increase the detection capabilities of the metal detector."

"I want to use this crystal to make a transmitting device to enhance the signal's penetration ability."

Sun Keke thought for a moment, then said, "Give me some magic cores from bats, overtone crystals, and paper money. I need to do some calculations and design."

She handed the items to him. Zuli then began preparing with Ivan.

The entire metal detector is approximately 10 meters tall. The main frame is made of iron. Its purpose is to serve as a support and main bracket.

The detector's interior primarily uses copper as the energy conduction circuit. Silver and gold are used to create the high-precision sensing array.

The most crucial signal transmission support is cast in gold. It is used to mount the signal transmission crystal.

During the forging stage, Zurich primarily acts as the furnace. Ivan manipulates the earth to create molds and cast the metal. After casting is complete, Ivan inspects the work.

After setting up the support frame, Ivan began to inscribe the runes.

Sofia watched her younger brother and husband bustling around with tenderness. "It feels like we're back on Earth. Back then, when our snowplow broke down, Grandpa was the one who fixed it, and Ivan could only stand by and pass me the wrench. So many years have passed, and Ivan has grown up and even has a wife now."

Having finished her design, Sun Keke sat down next to Sophia and asked with a smile, "Sister, can you tell me about Ivan's past?"

"Sure, let's start from when Ivan was little, when he ran away from home in a huff, and ended up with his snot frozen solid, and slunk back home..."

Ivan, in the distance, paused for a moment.

Su Li, who was adding metal nearby, suppressed a laugh, "You actually do this kind of thing?"

Ivan rolled his eyes. "I was only 7 years old then! Let me tell you, brother-in-law, when my sister was 10, she wore makeup for the first time... Sorry, sister, I got carried away. Can you put the gun down?"

Sofia, far away, fired a blank before finally letting go of her dream.

After joking around for a while, Ivan got to work.

He is now beginning to inscribe runes on this massive 10-meter-tall metal structure.

This thing is to be forged as a piece of equipment.

Su Li watched Ivan's actions and began comparing his runes with those of the other members of the team.

He specializes in crafting consumable items. He's not particularly skilled in runes. His runes are rather crude, focusing on squeezing the full potential of materials, resulting in high destructive power.

Sophia's runes, as a means of combat, do not require long-term stability but focus on energy utilization, which is somewhat similar to Zuli's runes.

Ivan's runes, on the other hand, were incredibly stable.

Each rune is like a complex lock. As equipment, stability is paramount. The rune array contains numerous structures to prevent rune degradation and damage. Su Li mentally calculated that even with 15% damage to these runes, the impact on the rune array's main performance would be minimal.

So Su Li had to remind him: "We're not making equipment. Once we find the train, we can abandon this thing."

Ivan paused, scratching his head somewhat sheepishly, "But this is the only kind of thing I know how to make..."

Su Li started to lend a hand, "Remove this part; we don't need any content related to anti-degradation. Then do this, and then this..."

Ivan watched as the runes were completely altered by Zuli.

This was a rare opportunity for rune exchange. After a while, Sophia and Sun Keke also came over to exchange ideas, as Sun Keke's craftsmanship also required rune design.

In the evening, Song Mingyu returned. She was also knowledgeable about runes and joined the discussion.

Outside the crowd, Sun Lili carried the corpses of two gold-level magical beasts and several treasure chests. "What's going on? This atmosphere where only I can't do it? Wait, I also know runes, I have runes related to the Sea of ​​the Mind..."

The group looked at each other, "Sorry, we don't need it..."

"What kind of extraordinary bullying is this? It's infuriating! When will our Mind Department finally be able to stand up for ourselves?"

Joking aside, the project is progressing very well.

Sun Lili, who was delighted to have taken on the role of a laborer, carried the overtone crystal, which was as tall as a building, and installed it in the core part of the device.

After being carved by Sun Keke, this overtone crystal looked like an ivory sphere.

Ultimately, Sophia's runes transformed the energy within the spiritual essence to power the device.

"It feels a bit like the laser cannons that aliens often use in games."

Sun Lili patted Su Li on the shoulder and said, "Stop talking nonsense and get to work. I want to go home!"

Sophia pressed the rune, and energy began to flow.

Silver patterns lit up gradually from bottom to top, like a galaxy pouring down, finally converging at the golden core at the top, bursting forth with a colorless and invisible enhanced lightning pulse, generating a rapidly changing alternating electromagnetic field that spread outwards.

A few seconds later, the gold-plated receiving coil did not detect any change in the magnetic field.

"No metal ahead. Change direction."

With incredible strength and power, Sun Lili lifted the device in one go and changed its direction.

I restarted, but still nothing. I tried changing directions again.

Unfortunately, nothing was found in any of the six directions: up, down, left, right, front, and back.

"Looks like we've got a lot to look for." Su Li sighed. "Let's go. No sleeping tonight. Leave two people to guard the camp, and the rest of us, we'll go find the train."
