"Goodbye, but don't forget our agreement!" After Art and others left, Marin and the other children followed them to the door and waved goodbye to several people.
"Do you have any agreement?" After hearing this, Apple Blossom, who followed him out, asked Marin out of curiosity.
"Of course it's an agreement between men!" Marin showed a happy and innocent smile towards Apple Blossom.
…
"I'm back."
After saying goodbye to Lansa and Mamo, Art took Tier back home directly. To be honest, Apple Blossom's cooking was not to his liking, but his own food was delicious.
I don’t know what skills Tiyi learned today when she came back.
"Welcome home, Master." As usual, Dee was standing behind the door waiting for Art, and Art also habitually slumped down on the sofa and casually picked up the books on the table to read.
"I'll go upstairs to replenish some magic stones. If you need anything, just call~" Tier waved her hand. She had been working almost all day today, and the magic stones should indeed be used up.
"Did you go there to play today? You actually took Tier out." Tiyi asked while sitting next to Art. Although her tone sounded the same as usual, she always felt that there was an extra layer.
meaning……
"Ahem, because there is nothing going on at school today, I went back home in the morning." Art naturally understood what Tiyi was talking about, and said with a slight embarrassment: "You know, you were not at home at the time.
"
"Yes, I went to Alice's house to learn cooking skills." Dee smiled and continued: "Okay, in that case, please taste my cooking. Although I can't taste the quality of the food, I
At least Ms. Corlando said it was good at the time."
"Of course, I will taste it." Art also walked down the steps provided by Tiyi. Although he wanted to sit down and rest for a while before eating, there was nothing he could do now.
"By the way, where's Ravens? He hasn't come back yet?"
But Art came to the back hall, looked around the kitchen and back yard, and was surprised to find that a certain man squatting in the kitchen on time was missing!
This is not quite right...
"I don't know. Indeed, according to his usual habits, he should be back now." Tiyi shook her head, moved Art's chair away from the table, then moved him to the chair, and then faced the table.
Perfect one-stop service.
"Haha, you also learned this from Alice?" Art was a little surprised. Although this was the first time for this kind of service, the experience was indeed good.
"Yes, Alice told me that if she has a child in need of help, she can provide him with such help." Tiyi said with a smile.
"Well, it sounds a bit weird...forget it, I'll just do it myself from now on."
After finishing the meal, I have to say that Tiyi's skills have improved very quickly, and the dishes she made are very good. She has the ability to be a restaurant chef, and she can make many different tricks with just a few simple ingredients.
The only regret is that Ravens did not come back, which resulted in a much larger portion of food, and Art could not ignore the capacity of his stomach and serve it all in one pot just because it was delicious.
I can only pity these foods...
After dinner, Art immediately returned upstairs to his room. He looked at the anvil that had not been used for a long time and immediately made up his mind.
This world is so scary! Bandits can be seen everywhere outside the city, wild beasts are waiting for opportunities in the desert, and even riots may suddenly occur in the city. Boys like me must protect ourselves at all times when we go out!
Swords and the like are only for the bravery of ordinary men, armor and others are just for survival, only real guns and live ammunition can carry out one's own justice!
...But of course, it is unlikely that real guns and live ammunition will be born from an anvil.
What Art plans to make first is a small thrower to quickly throw the thermite grenade he made before. This small device should fit the size of a minor, and the weight is best concentrated on the wrist. It can be used by a dwarf.
The force amplitude of the glove is offset.
The device requires a high-strength spring and its matching contraction mechanism, an ultra-small engine (the power does not need to be high, it can be replaced by instruments from this world), a bomb release port, and a trigger device.
This device is very simple and user-friendly. Art even just drew a sketch at random in a book and determined the operation process - after placing the thermite grenade at the bomb release port, the device will automatically ignite it, and then use a compressed
The spring ejects it out, and after the end, the small engine resets the spring again to complete a cycle.
As for how far it can be ejected, it depends on the material of the spring.
Now there are three options that you can use. One is iron-carbon alloy, which is commonly known as steel. Although this thing is quite common in reality, if you can control it without any instruments,
The carbon content is still a bit difficult...but it's just difficult, and it's not completely impossible to control.
The second is the sandworm alloy that has been tried before. According to Yat's initial observation at the time, this metal has a fairly good toughness, is not difficult to cast, is relatively rough in terms of iron content control, and also has magic.
In terms of applicability, it can be considered as the main option.
The third is the sand scorpion alloy used before. In terms of hardness, as long as it is blessed with magic stone, it is definitely the best. However, the strength is really terrifying. Although the casting is relatively easy, Art is deeply doubtful.
This thing cannot be moved by a small kinetic energy machine.
As for ordinary cast iron, the most common cast iron on the market, Art just excluded it and did not consider it.
In terms of prioritizing craftsmanship, Art decided to make springs first, which were relatively simple. As for the kinetic energy machine, since we have come to such a magical world, of course we have to try a fresh magic stone furnace, but the magic stone furnace
I still don’t understand how it works, so I’d better go to Teacher Sarayetti’s when I have time tomorrow and ask if there are any corresponding books I can look up.
After having the target, Art took out the sandworm carapace fragments that he had collected for a long time, and asked Tier to help move the anvil to the open space in the backyard. After lighting the fire, he began to melt the sandworm alloy.
With his previous experience, Art easily obtained a small bucket of molten sandworm alloy.
However, if you need to break away from the mold to make a spring, you need the combined efforts of three people. Two people clamp the two sections of the red-hot iron bar respectively, twisting them in opposite directions while constantly approaching each other, and the two people are close to each other.
The speed of approach determines the radius of the spring.
The third person acts as an assistant and uses external force to adjust the curvature and size of the spring.
"Tiyi, Teal, come on, we need your help here!" Ate shouted, and Tiyi and Teal, who were watching from the side, immediately came to Ate's side.
