Wang Shuo became very busy, he always locked himself in his room and thought about his own affairs.

The affairs of Tianwei City are stable, and he doesn't need to do everything himself. He didn't ask much about the things outside, and it seemed that everything was in order.

In the room, there are many crystals on the floor, and there is a pile of residue on the ground.

On the table, there are many lenses, made of crystal.

On top of that, it's some iron pipes.

What he wants to do now is very simple, he doesn't need to be of a high level, he just needs to make it.

That's the telescope!

The principle of the basic telescope is not difficult, a lens and a magnifying glass can be used, and an upper concave mirror can also be used, Wang Shuo is no stranger to this thing.

It's just that he needs to make the lenses by himself, and here, the only thing he can think of is crystal.

On top of that, there was a lot of paper in the room.

He was perfecting the blueprint of the siege crossbow given by the old man, and correcting it according to his own advanced concept, so that it could be made more easily.

Except for Xiao Lu, who was in charge of delivering food, no one would disturb Wang Shuo at this juncture.

It took half a month for Wang Shuo to leave the room for the first time, and there were already people waiting outside, it was Niu Bai and the stone monster.

The stone monster probed his head and glanced inside, "Master, what are you doing? ”

"Close one eye and look with this. ”

Wang Shuo handed a single-barreled telescope to the stone monster, and the stone monster looked at it curiously, "What is this?"

Wang Shuo smiled and handed Niu Bai another one.

Niu Bai is also curious, because this thing doesn't look like a weapon no matter how you look at it.

"Wow!"

The stone monster glanced at it, hurriedly put it down, put it on his eyes again and began to move and watch, and couldn't help but be surprised: "Master, what is this? How can this be...... It's as if something in the distance is getting closer. ”

Niu Bai was quite surprised, and he also used it himself, and quickly took it down as soon as he put it on, because he suddenly felt that the thing in front of him had become bigger.

Wang Shuo smiled and said nothing, just let the two of them experiment.

After a while, the two were still in a state of excitement, and they couldn't help themselves.

"Lao Wang, what kind of spell is this?"

Niu Bai was surprised: "Did you add a spirit talisman or something to it, but I think it's also very common." ”

"It's called a telescope. ”

Wang Shuo smiled: "Even if it is used by ordinary people to see things in the distance, the result is the same as yours." ”

"Telescopes?"

The stone monster smacked his tongue, "It seems to be quite far away." ”

The voice fell, and he shouted, "Daosan, come here." ”

Dao San heard the voice in a hurry, and hurriedly rushed over, and said in a deep voice, "What happened?"

"Haha. ”

The stone monster laughed and put his arm around Michizo's shoulder, "Here, use this to see, you have to close one eye." ”

Dao San frowned, "What are you doing?"

"Hurry up and see, I don't lie to you. ”

The stone monster smiled, pretending to be mysterious.

Dao San couldn't help but look at Wang Shuo, Wang Shuo smiled and said, "Try it." ”

Dao San took the telescope at this time, his complexion changed suddenly, he took it down in a row, put it on several times, and then checked it carefully, and said blankly: "Master, this is ...... This...... What's going on?"

In this telescope, he did not feel any power.

The distance between things can be seen in an instant, but it is several times, more than ten times closer.

"It's just a gadget. ”

Wang Shuo smiled, "I'm just sitting here and explaining to you, and you may not understand, so don't ask." ”

It's not that I cherish myself, I really can't say.

Do you want to discuss with them the problems of small hole imaging and then using a magnifying glass?

Niu Bai said happily: "Lao Wang, do you want to give me this thing?"

"Give. ”

Wang Shuo said with a smile: "The worthless thing is a tool that allows people to observe the surroundings of Tianwei City in the future. ”

With this thing, as long as you look closely, you can still see it clearly.

The stone monster snatched the telescope of Dao 3 and laughed, "I'll take it and play with it first." ”

Dao San was angry, "What are you anxious about? I'll see again." ”

"Go to the head of the house yourself. ”

The stone monster laughed and walked away.

Dao San gritted his teeth angrily, "This guy is really unqualified." ”

Wang Shuo smiled: "By the way, Dao San, I need you to help me in a while." ”

Dao San nodded and said, "No problem." ”

When the words fell, he said with a little embarrassment: "Master, this telescope ......"

"There was ...... in the room.

Before Wang Shuo finished speaking, Dao San had already rushed in, grabbed one and stuffed it around his waist, and said solemnly: "Master, what did you just say you wanted me to help with?"

“......”

Wang Shuo was speechless for a while, so he had to say: "Regarding the matter of the siege crossbow, I have made some modifications, and it is not difficult to build it. Now it's a matter of starting to smelt the material and make the mold. However, you may need your rune technique to help. The craftsmen here are relatively ordinary, and compared to the refiners of the level of the cultivator, the gap is really too big. ”

Speaking of this, Wang Shuo couldn't help but laugh dumbly.

Practitioners, refiners, sometimes it's really stupid and can't tell the difference.

Dao San smiled and said, "What's so difficult about this?

Wang Shuo nodded, went back to the room to get the drawings, and went with Dao San to find the ten refiners who were brought by Niu Bai. Those people are naturally very idle now, but as a refiner, they are still a little arrogant.

It's a pity, how did they know that Wang Shuo didn't look down on them at all?

"City Lord. ”

The ten refiners shouted a little perfunctorily, no matter how strong Wang Shuo is, he can't control them, right?

Wang Shuo called ten refiners and spread out the drawings one by one, the drawings had already been analyzed by Wang Shuo, such as the size, materials, overall assembly, etc., all of which had been calculated by actuarial calculations.

With Wang Shuo's explanation, the ten refiners looked awe-inspiring, and their attitudes towards Wang Shuo became more and more respectful.

"There are some materials that I need to make tough, such as ......"

Wang Shuo pointed to one of the parts and explained it according to his own ideas, which naturally involved the production of the mold.

The ten refiners could only memorize what Wang Shuo said with all their might, and they also felt that their own knowledge was useless in front of this city lord.

Their duty is purely to become craftsmen of iron.

Wang Shuo said for nearly an hour, and then straightened his waist, "The third brother of the Dao will draw some spirit runes for you, so that it can ensure that those materials can better remove impurities in the process of quenching, and it is easier to quench." ”

After the words fell, he said, "Do you think, how many days will it take to make one for me?"

One of the refiners stepped forward and said respectfully, "Lord City Lord, the younger one's name is Feng Gang. Since the adults are in urgent need, we will do our best, and in ten days, ten days, we will hand over the first thing to the lord of the castle on time. ”

Wang Shuo said: "Don't be too anxious, what I need is success, not failure." ”

Feng Gang hurriedly said: "City Lord, don't worry, after what you say, we already know it in our hearts, and we will definitely not let you down." ”

Wang Shuo smiled: "Okay, at that time, I will definitely not treat you badly." ”

When Feng Gang heard this, he hurriedly bowed down to thank him, and the others also saluted.
