"I didn't expect there to be another exit underground, but only the iron-toothed boss knows the details, I don't think I can believe it. Ice Bear Abyss leaned back in his chair with his hands on his chest, "I think that exit must be the same as the box exit I'm looking for now." ”

"I think so, too, the installation club and Screw Alley are mostly aware of the existence of that exit. Catherine sat across from the Ice Bear Abyss, the iron tooth of the trade on the table between the two.

"They know for sure. Ice Bear Abyss gestured with his chin to the iron teeth on the table, "This thing can obviously be obtained by bartering, and it is impossible that the Device Club and Screw Alley have not been exchanged." Maybe we can ask the mountain and casting directly, and we can ask for some relevant information. ”

"Why don't we split up. Catherine proposed, "I'll go find the mountain, and you can talk to the casting." ”

"Good. Ice Bear Abyss stood up, "I'm just about to practice flying, and the casting should be adapting to Iron Feather." I'll go to the training ground right now. ”

Catherine and the Ice Bear Abyss exited the shop and went their separate ways. Catherine didn't rush to find the mountain, but went to the ingredient room. If she wants to improve the air cannon, she needs to find some metal plates to practice alchemy pattern carving.

Grabbing a few metal plates in the batching room, Catherine walked into the repair room diagonally across from the batching room. Rounding the hill of parts, she saw the assembler Tu working at the metal bedside.

Lying on the metal bed is an incomplete metal body of a female, with no head or arms, but a right leg, and Tu is mounting the left leg.

Catherine stood silently and watched until Earth attached her second leg to her metal body.

Dirt put down his tools and turned to look at Catherine. "What's the matter with you?" he asked.

"I need some tools at my disposal. Catherine raised the metal plate in her hand, "I'm going to engrave some alchemical patterns." ”

Tu said: "You have seal carving tools in your shop, do you want to carve precise patterns?"

"It's a delicate pattern. "Catherine has seen the improvement plan of the air cannon that the old wrench gave herself, and the alchemy pattern is very complicated, and ordinary seal carving tools can't handle it at all.

"I don't believe it. The metal head of the earth shook from side to side, "I know all the people in the entire Gear City who can carve precise patterns, without you." ”

"I've got a draft of the pattern here, you might as well take a look at it. Catherine pulled out the plan she had gotten from the old wrench, "Actually, I want to improve the air cannon, if you can re-engrave the air cannon according to the style of this draft, I can leave it to you." ”

Tu took the draft and looked at it for five minutes before he said, "This is too complicated, except for the old wrench, probably only the casting mold of the installation club can be carved." I can't achieve this kind of accuracy. ”

"So I want a tool that can carve this kind of delicate pattern. ”

"Seal carving of this precision can only be done with special seal carving tools. Tu walked over to the metal cabinet next to the metal bed, and pulled out a pair of glasses and a pair of metal finger knives.

"I have two special seal carving tools that I can lend you. "But you have to add tentacles to your eyes and fingers before you can use it." ”

"How effective are these two things?"

"The long barrel is used to magnify the grain, up to fifteen times, and the thinnest cutter in the finger knife can cut through the hair. After Tu introduced the special seal carving tools, he added, "I can add a touch to you." ”

When Catherine heard this, a strange feeling flooded her heart. Since coming to Screw Alley, she has been trying her best to avoid the transformation of her body, but the situation forced her to increase the degree of body transformation little by little.

Now Catherine finally realizes that if she wants to learn more about the making of machine golems, and the seal carving of alchemy patterns, transforming the body is the basic premise. Perhaps the rain didn't really agree to teach Catherine the alchemy of the machine puppet, because he saw that Catherine was unwilling to further transform her body.

Catherine figured this out and decided to follow her instincts. "I'm not going to install the contacts just yet. ”

After hearing this, he turned around and walked back to the cabinet and put the special tools back.

"You just said that there are people in the Device Club who can carve this kind of delicate pattern, don't you have one in the Iron Tooth Bar?" Although the seal carving tool could not be borrowed, Catherine had no plans to leave. She was going to use the opportunity to inquire about the underground exit again.

"Of course there isn't an iron tooth bar. What kind of lines do you think they can carve with their claws?" said Tu with a hint of a smile in his tone.

"Then what if they want to carve a precise pattern?"

"Come to us or install the club, as long as there is enough to pay, you can engrave for them. ”

Catherine caught something from this sentence and hurriedly asked, "Then have they asked you to carve a seal?"

"I found it. Tu walked back to the metal bed and sat down, picking up a part and grinding it.

"Have you ever changed to Iron Tooth?" Catherine said quickly, "the kind of Iron Tooth that can safely get in and out of the Iron Tooth bar once. ”

"Huh?" Dirt looked up at Catherine, "You want to change the Iron Teeth?"

"Nope. Catherine shook her head, "I've heard that you can go to the underground exit to enter the Iron Tooth Bar. ”

"I haven't heard of any underground exits. Soil lowered his head and polished the parts in his hand, "The Iron Tooth Bar is underground, so if you want to go, you will go through an entrance to the underground. No one can get through that entrance without iron teeth. ”

Walking out of the repair room, Catherine was still thinking about the words of the earth. The Iron Tooth Bar is underground, and the Iron Tooth Bar can indeed be traded in exchange for entering and exiting the Iron Tooth Bar, and the Iron Tooth is used to pass through a special underground entrance, but that entrance is obviously not the deep well cavern from which he and the Ice Bear Abyss escaped from underground, and most of the time it is impossible to get to the Iron Tooth Bar from there.

The mountain is not in the screw alley now, and Catherine asked the soil before leaving, but the cloud is there. According to Tu, Yun should be at the training ground at this time.

The training ground is on the opposite side of the weapons shop.

Catherine's first visit to the training ground, which is a very large open-air venue with a view of the towering steel buildings of Cogwheel City. Catherine looked up to see two small figures flying around in the sky surrounded by three or four steel buildings, presumably Ice Bear Abyss and Cast practicing flight.

Retracting her gaze, Catherine looked around and spotted the figure of the cloud in the corner of the field. She sat on the sidelines, as if wiping her weapon.

Catherine walked over and saw two torn machine golems lying on the ground, the shards of which were flat cuts.

The cloud was wiping down the two new elbow knives. As Catherine approached the clouds, she suddenly raised her head and rushed towards her with a knife.
