It's right to think about it. The giant's corpse will evaporate and nothing can be left. It's already great that Han Ji can sort out a bunch of handwriting.

Han Ji was already waiting for Mo Tie in the house. She mainly wanted to learn about the special skills in Mo Tie forging, and then study whether there is room for improvement.

After hearing what she meant, Mo Tie said, "So it's this. I'm afraid you'll be disappointed. The method I used can no longer be improved within the wall."

In Han Ji's concept, the only remaining humans in the world are inside the wall, so the meaning of Mo Tie's words is understood by her as "already the top technology of this era."

"Awesome! Are you convenient to talk about it?" Han Ji said excitedly. She was interested in all the awesome things.

"Yes. There is no special thing in principle. Like other blacksmiths, they are mixed with charcoal and wood ash during the forging process, but what I do more than them is precise control."

“Precise control?”

"Well, normal craftsmen make weapons and dopant charcoal, and they judge the completion degree of weapons based on their naked eyes and experience. Before forging, I will prepare a specific weight of charcoal powder based on the weight of the weapon, and mix all the charcoal powder into the weapon, and then I can create an iron with consistent hardness and toughness."

Mo Tie explained in detail.

Han Ji nodded thoughtfully: "Is the ratio problem?"

"Yes, this is a precious data inherited from our family. It is only reserved for direct descendants, and ordinary apprentices will not teach it." Mo Tie said proudly.

"It's understandable, but have you ever thought about improving the data?"

"I thought about it, but it was useless. This is the best data in the charcoal doping method. I have tried many other ratios, and there is no one that has more hardness and toughness than it."

Han Ji was excited and slapped the table: "Then keep testing! Not only charcoal, you can try to mix something else; and it doesn't have to take into account both hardness and toughness. We have many instruments that focus on certain properties. You'd better test all the data, the hardness is the best; the toughness is the best; the strongest strength is the best, etc.."

"I don't care, but are there so many raw materials to test?"

"Don't worry, you can do it." Han Ji promised, "We will be given priority in the entire wall."

This is just a small episode, it doesn't matter what Mo Tie does, anyway, he will leave after half a year.

So he started working, and his room became a place to change equipment. In addition to knives, there were three-dimensional motorized devices and gas tanks. He was responsible for handling everything that could be forged.

Alvin also asked Han Ji to send various equipment drawings with detailed structure and size data.

A few days later, Alvin sent someone to inform him that the Wang government would send a group of refugees to the Maria Wall in one month to reclaim wasteland. Not long ago, the equipment investigated outside the wall should be replaced in an effort to speed up the replacement of the equipment.

The sound of irons echoed in the barracks all day long, "Ding Ding Ding..." and constantly trained the soldiers' will.

Everyone was surprised that Mo Tie could knock on it all day and his endurance was very long.

He even gained some fake fans and asked him for ways to improve his endurance in the name of admiration. After all, the daily training of the Corps is very laborious.

Among the female soldiers, there are many who are good-looking, and Mo Tie will refuse anyone. Even if he doesn't get it, it's good to keep it pleasing to the eye.

The male soldier is stricter, he ignores his bad tone, and throws him out if he is provoked.

After a few times, no one dared to cause trouble again. Everyone respectfully asked for training methods, and even when changing equipment, they were in order.

Half a month later, Mo Tie rarely rested for a long time and lay on the lounge chair at the door to bask in the sun.

After a while, a tall man with yellow hair ran over and shouted anxiously: "Iron, my catapult is broken again. Please change me a new one, don't let anyone discover it."

Mo Tie got up helplessly, took his three-dimensional mobile device, checked it and said, "You have broken two of them in just ten days. If this continues, I will tell the team leader."

The young man pursed his mouth and said unhappily: "It's obvious that you didn't change it for me, I still have to tell the team leader."

Mo Tie smiled: "Haha, you have the nerve to say that others have told me that you can break the catapult on the device in three days, and what I have replaced you with are all good goods."

"Okay, Brother Ain, it's my fault. Don't tell the team leader. I promise to use it well this time." The young man begged.

"Forget it, you'd better not use it. You're not using it incorrectly, but using it too many times. I really don't understand why you like flying in the sky so much? Does gas gas cost money? Is it?"

Mo Tie rolled his eyes and said.

Yize smiled, looked at Mo Tie to replace parts for him, and said, "Why don't you like flying? Every flight is from a different perspective and you can see different scenery."

Mo Tie glanced at him and said, "Do you like different scenery so much?"

"Of course, before I joined the Corps, I had already walked all over the Wall of Rosse, and I had long been tired of seeing the markets and villages. I wanted to go outside the wall to see more scenery, which must be spectacular."

Izawa said with his eyes lit up.

"I don't know whether it's magnificent or not. I just know that you may die in the mouth of a giant." Mo Tie said angrily.

"Hahaha, how is that possible? I fly in the sky every day. No one in the Investigation Corps is better at using three-dimensional mobile devices than me. Even giants don't want to catch up with me."

Ize laughed loudly, looking like "You're over-concerned".

"Change it, take it. Don't stand it casually." Mo Tie threw the three-dimensional mobile device to Yize and taught him by the way.

"What Fulig?"

"Nothing, get out of here."

After driving away the yellow hair, Mo Tie continued to bask in the sun.

The young man just now was actually quite interesting. When Mo Tie met him, he almost thought that his real name was Ezrel. He was very exploratory and liked to see unknown scenery. He heard from others that during the investigation outside the wall, he always actively investigated the terrain and investigated the movements of giants.

A budding explorer!

Not long after I lay down, the sun was blocked again.

Mo Tie opened his eyes and it was Han Ji.

"What's wrong?"

Han Ji looked a little serious, and she said solemnly: "Ain, do you want to join the Investigation Corps?"

"Ah? Am I here now?" Mo Tie asked strangely.

Han Ji thought for a while and said, "This is how you come with me."

Mo Tie stood up and asked, "Where are you going? I will take a rest once every half month."

Han Ji had turned around and walked in front, saying, "It won't delay you for long."
Chapter completed!
