Xu Chen took it in a hurry, didn't pay attention to the appearance at all, and put it in front of him, opened one eye and closed the other, and carefully inspected the inner wall of the hollow steel bar.

The threads are compact and regular, and he hurriedly stretched out his middle finger and inserted it into the hollow steel bar, carefully checking the thickness of the pipe wall, and it was really exactly the same, almost all of them were of the same thickness.

"Not bad! Not bad!" At this moment, Xu Chen's heart was already overwhelmed by ecstasy, but his face tried his best to suppress the joy in his heart, just smiling normally.

Xu Chen has already seen the quality of the steel plate on the armor just now, whether it is hardness or flexibility, it is no worse than the forging steel, and then looking at the level of drilling now, it has also met the requirements.

"It seems that the civilization of 10,000 years ago didn't need to make more concessions in terms of metal smelting than later generations!"

Xu Chen was extremely satisfied, with the hollow steel pipe in his hand, the biggest technical problem had been solved.

"By the way, if I want to build a longer and thicker hollow steel pipe, I wonder if it's possible?"

"Or do you want to drill holes like this?" asked the shopkeeper.

"Yes!" Xu Chen nodded hurriedly, his face full of anticipation, this time, he did not suppress his desire again.

"This ......," the shopkeeper pondered for a while, and then asked, "How long and how thick?"

"There's a play!" Xu Chen's heart trembled, and he hurriedly replied: "It is about a zhang Xu Lai long, the diameter should be one foot, and the thickness of the pipe wall is about four inches." ”

"That means at least half of it will be removed?" asked the shopkeeper again.

"Yes, but the outer wall at one end can be thicker, and it shouldn't be difficult to leave more when cutting, right?" Xu Chen asked expectantly.

"Well...... shopkeeper hesitated.

"It's still the same, as long as it can be made, money is not a problem!"

At this moment, Xu Chen only wanted to know if the technology of the cultivator world could meet his requirements, and as for the money, he would have to find a way.

"It's not impossible to make it...... the shopkeeper seems to be well versed in the method of doing business, and after fully satisfying Xu Chen's appetite, he said: "It's just that you also saw that I don't have such a big drill here, but my master has it!"

"I don't know who the shopkeeper's master is?" asked Xu Chen.

"My master is a master craftsman in the weapon workshop of the City Lord's Mansion, and his craftsmanship is first-class in the whole city!" the man said proudly when he heard this.

Xu Chen hurriedly showed a look of admiration, and said in surprise: "I see! No wonder the shopkeeper's skills are so superb, he is really a famous teacher and a high apprentice!"

"It's not worth mentioning! It's not worth mentioning! I haven't even learned the master's fur at this little skill, I'm ashamed, ashamed!" The shopkeeper was a little embarrassed by Xu Chen's naked praise, and hurriedly said modestly.

"Okay! I'll go back for the time being, and I'll come back after drawing a detailed drawing in a few days!" Xu Chen's words are naturally a pretext, just the small hollow steel pipe in front of him, Xu Chen doesn't know if he can afford it, let alone the longer and thicker, more cumbersome large hollow steel pipe.

"It's easy to say! If the guest officer comes again next time, I will definitely give the guest officer a reasonable price!"

"Then thank you!" Xu Chen thanked him, and then asked, "I don't know how much this steel pipe is worth?"

The shopkeeper glanced at Xu Chen and said, "Ten taels of gold!"

"What?" Xu Chen and Yang Ziyun were both shocked!

Yang Ziyun only woke up yesterday, and Xu Chen didn't have time to explain the price here to him, but when he went out this morning, he put a dozen taels of broken gold in the house. When Yang Ziyun went out in the morning, she thought that it would not be good to visit empty-handed, and that she should bring some things to Xu Chen's workers, so she pulled a girl named Selling on the street and bought a basket of melons and fruits in the hands of others.

This basket of melons and fruits cost Yang Ziyun five taels of gold! It's just that Yang Zihua saw that the basket of melons and fruits was strange and extraordinary, and the fragrance was refreshing, thinking that this was in the realm of cultivators, and it was estimated that this melon and fruit were not ordinary. So, I gritted my teeth and bought it!

When she was shopping all the way just now, Yang Ziyun just said "Buy, buy, buy!" It was Xu Chen who paid the money, and it was not clear how much money she had spent.

So when I heard the shopkeeper's words, I was immediately shocked! What are you kidding, such a black iron rod dares to ask for ten taels of gold? Blatantly robbed, right? If that treasure armor is about the same!

Saying that, Yang Ziyun was about to get angry, but Xu Chen hurriedly grabbed her.

Compared with Yang Ziyun, who doesn't understand prices, although Xu Chen is shocked at the moment, he is pleasantly surprised!

Is ten taels of gold too much? Not much at all! This made Xu Chen, who was originally ready to be slaughtered, very happy!

After Xu Chen's understanding, the average income of the people in Biancheng is about seven to eight taels of gold per day, although the price of Biancheng is not low, but the cost of three meals a day per person is only three or four taels of gold. This proportion is not to mention that compared with those slave-like ordinary people outside Biancheng, even in the outside world, the proportion of food expenditure of well-off families in the total income is much higher than this. Even if it is placed in Xu Chen's original era, the Engel coefficient is much higher than this!

And Xu Chen's job can be regarded as a special type of work in Biancheng, and his income is already more than ordinary people.

Xu Chen worked on the dock on the first day, and only earned more than four taels of gold, but as Xu Chen's body gradually rose, the wages of the next few days were about ten taels, and today he was doubled by Yun Ye's wages, and now Xu Chen has a hundred taels of gold on his body, except for the money spent on shopping just now, there are more than seventy taels of gold left.

If Shi San is changed, that guy is talented, and his daily salary is thirty or forty taels of gold, which is more than Xu Chen's salary after doubling!

So, for me, ten taels of gold is really nothing!

But for the blacksmith shop, ten taels of gold is equivalent to half a day's income, and the most important thing is that the cost of such a hollow steel pipe is really not high for the blacksmith shop!

That steel bar only costs a few dollars of gold, and although drilling can be regarded as a technical job, this bit of technology is really nothing compared to making armor and blades suitable for the ability of the people! Even if you count the labor cost of the shopkeeper, it is only one or two gold, but now it has increased tenfold, and the shopkeeper feels that he is already very profitable!

In this way, after seeing Xu Chen and the others all showing shocked faces, he hurriedly said: "Haha, I have a relationship with the guest officer today, so let's get a seven-fold discount!"

This time it was the shopkeeper's turn to be anxious, and seeing that Xu Chen was still groaning, he said again: "Actually, I really didn't make much money from you with this thing, if you want to talk about this technology, there are really many people in the city who are better than me." Especially those refining workshops run by those cultivators, I am afraid that as long as they make tea, and the craftsmanship is more exquisite, the materials are naturally better! But it is impossible for a dignified cultivator to do something for us mortals, right?"

"What are you talking about?" When Xu Chen heard this, he didn't care about dwelling on these few taels of gold, but grabbed the shopkeeper's words, and hurriedly asked, "What kind of refining workshop do you say those cultivators can make better quality?"

"Of course!" The shopkeeper suddenly laughed and said, "People are cultivators, and they all use magic to refine weapons, but they don't work as hard as us!"

"Let's just say such a hollow steel pipe, if you want to meet the requirements of the guest officer, I must first cut a whole steel bar, and then drill holes hard, and pay attention to the thickness of each place, as well as the threads on the inner wall. ”

"But if you change the cultivators, it is directly driven by divine consciousness, smelting by earth and fire, not to mention the speed, and the material is not the ordinary steel plate we use, and there is almost no possibility of failure!

"Hahahaha......! This...... Why didn't I think of this?" Xu Chen had a smile on his face, his expression was a little sluggish, but in fact, he was already excited in his heart!

"That's right! Since these ordinary people can have such superb metal smelting skills, there is no reason why those cultivators will be worse! Let's just say that the flying swords they got, although they are smaller, which one of them is not as sharp as clay?"

"Haha, that's good! Not bad! The smelting skills of the cultivators must be even more superb!"

Xu Chen was happy in his heart, but his face showed a bitter color: "What about this...... But how can the immortals have the kung fu to help us? If we spend money...... Alas, a spirit stone is equal to a million taels of gold, so when do I have to save it!"

"What the guest officer said is right, how can the cultivators of the people care about us little people?" said the shopkeeper comfortingly.

Xu Chen pretended to sigh helplessly, and after paying ten taels of gold, he took the hollow steel pipe, led Yang Ziyun, and left the blacksmith shop a little lonely.

After the two turned an alley, Xu Chen "cheered up".

"Hahahaha, great! great!" Xu Chen raised the hollow steel pipe from time to time to take a closer look, and couldn't help but be happy.

"Are you so happy? Soon a pipe will break!"

Xu Chen only cared about the steel pipe in his hand, and when he was shopping just now, Yang Ziyun was carrying all the things in his hands at the moment, and the girl suddenly said angrily.

"Hey, hey!" Xu Chen walked over, and after taking half of the things, he walked side by side with the girl, sharing his joy with him: "You don't know, with this thing, I can have one more hole card in my hand!"

"Huh?" Yang Ziyun was puzzled.

Xu Chen didn't say anything, but took Yang Ziyun to turn a few more alleys and came to another street.

"Where are you going, this is not the way home!" asked Yang Ziyun.

"Hehe, go get some of the things I ordered earlier, and if I can make it, I will be able to ...... it again"

"Can you have one more hole card?" said Yang Ziyun angrily.

Xu Chen smiled stupidly: "Wait a minute, I'll talk to you in detail when I get home, okay?" R1058
