"According to his son's inference, the industry in Lu Chen's Lujiazhuang does not seem to be developing outside Chang'an City!" Xiao Rui took a sip of tea from the teacup, moistened his throat, looked at himself and said.

Seeing Xiao Rui drinking tea, Xiao Yu subconsciously picked up the teacup and took a sip, then tapped on the arm of the chair and thought for a while, before saying leisurely: "It seems to be true!" ”

Even a few days ago, I heard that a few Hu merchants bought goods in "Shengshi", and two Hu merchants had already gone west with some of the goods, but that was Hu Shang, to put it bluntly, this batch of goods was sold outside the Tang Dynasty, and the stores of "Shengshi" were still concentrated in the east and west cities of Chang'an City, and I never heard that "Shengshi" intended to open branches in other towns, so Xiao Yu agreed with his eldest son's analysis.

"Since Lu Chen's industries are concentrated in Chang'an City and Lujiazhuang, then it can only mean one thing, that is, the raw materials that Lu Chen needs must not be too far away from Lujiazhuang!" Xiao Rui rubbed his teacup and continued to analyze, "Moreover, my son heard that before Lu Chen contributed to the method of iron smelting, what he mastered was only a small iron mine, and the carboniferous mine was not very far from Lujiazhuang, yes or no?" Xiao Rui looked at Xiao Yu and continued to ask.

"It's true!" Xiao Yu nodded.

"Since this is the case, then the son speculates that if this Lu Chen really wants to do this salt business, he will definitely not look far and far to find the salt producing area, but when the son was a child, he heard that there were poisonous salt mines around this Chang'an City!" Xiao Rui continued.

"Not bad!" Xiao Yu nodded even more simply this time, if it comes to the mastery of the "salt origin", their Xiao family said first, no one in the entire Tang Dynasty dared to say second, what are the salt mines and poisonous salt mines around Chang'an City, it can be said that Xiao Yu is clear, was reminded by Xiao Rui, Xiao Yu directly appeared in his mind The location of several toxic salt mines came out, and coincidentally, one of them happened to be in the back mountain behind Lujiazhuang.

"Son, do you mean to say that Lu Chen's salt is extracted from the poisonous salt mine in the mountain behind Lujiazhuang?" Xiao Yu looked at Xiao Rui and asked.

"Quite possibly!" Xiao Rui nodded directly, "That Lu Chen often does things that 'ordinary people can't reach', and my son thinks this salt," Xiao Rui said and pointed to the refined salt in the bag, "It is very likely that Lu Chen used some method to refine it from the poisonous salt mine!" Xiao Rui continued.

"If that's the case, then wouldn't our Xiao family be in calamity!" Hearing her son's analysis, Xiao Yu became a little worried again, and muttered a sentence in her mouth.

"This is just my son's speculation, it's best to send someone to investigate!" Xiao Rui saw his Ayana's worried look, and said directly in a comforting tone.

"But now that the whole area is Lu Chen's fiefdom, how can ordinary people and others get in?" Hearing Xiao Rui's words, Xiao Yu still said sadly and helplessly.

"The investigator does not necessarily need to go deep into the hinterland, if you go around from behind and observe from a distance, you can understand the general idea!" Xiao Rui continued to comfort his father and said.

"That's all there is to it!" Xiao Yu nodded, "I hope that Lu Chen doesn't have this ability!" Xiao Yu sighed and said.

As for arranging someone to investigate, it is naturally Xiao Rui's turn to talk more, after all, when it comes to the familiarity with this Chang'an City, his Aye is much stronger than himself, who has returned from Yizhou.

This matter is over, Xiao Yu and Xiao Rui gossip for a while, among which Xiao Yu naturally mentioned Xiao Rui's return to report on his work this time, and let Xiao Rui have time to visit Li Shimin.

Xiao Yu is naturally on the side of the crown prince Li Jiancheng now, but the family does things, it is impossible to put eggs in one basket, he, the assistant of Lao Tzu, Li Shimin, naturally wants to let the eldest son stand on the other side, of course, before finding out the situation, Xiao Yu does not allow Xiao Rui to participate too much, and only let Xiao Rui contact Li Shimin, and leave a thought, even if Li Jiancheng really does not succeed in the future, he is unlucky to be a father, doesn't he still leave Xiao Rui for the Xiao family such a breath!

Of course, this Xiao Yu arranged it like this, if Lu Chen knew about it, Lu Chen would laugh at most, after all, when it comes to betting at both ends, what Lu Chen admires the most is the old thing Feng Deyi, this "double agent" finally got mixed into the position of prime minister in Li Shimin's place, and became the right servant of Shangshu to shoot, this thing is very good.

Even this old boy's son Feng Yandao also mixed up with Li Shimin to become an uncle Lang, married Li Yuan's twelfth daughter, Princess Huainan, and when he arrived at Emperor Wu, he was also mixed into Shangzhu Kingdom, this thing has to be said, "The son inherits the father's business" is still quite powerful, but with Lu Chen here, whether this Emperor Wu will still appear is another matter.

As for how Xiao Yu and Xiao Rui, the two fathers and sons, study countermeasures, Lu Chen naturally doesn't know, even if he knows, Lu Chen won't care, Lao Tzu can turn poisonous salt mines into salt, what can you do with Lao Tzu?

Lu Chen is now in the workshop area watching Xu Gaofeng and his son install Jenny's spinning machine according to the drawings, with this thing, you can spin thread, spin wool, spin wool yarn can weave sweaters, with woolen sweaters, you can say goodbye to this brocade fur.

Compared with this somewhat cumbersome brocade fur, Lu Chen prefers light and warm clothes.

Lu Chen looked at Xu Gaofeng and his son intently, to say that this Mo family heir is really ingenious, he can really make things with drawings, looking at the Jenny spinning machine that is gradually taking shape, Lu Chen is in a better mood.

Soon, a Jenny spinning machine appeared in front of Lu Chen.

"Grandpa, it's installed!" After Xu Gaofeng wiped his sweat, he rushed to report to Lu Chenyu.

"Hmm!" Lu Chen nodded, "Hard work!" Go back to Lao Duna to receive the reward! Lu Chen circled around Jenny's spinning machine, and then said to Xu Gaofeng and his son.

"Grandpa Xie!" The father and son rushed to Lu Chen in unison to salute again.

"Where's the wool?" Lu Chen sat directly in front of Jenny's spinning machine, and then asked.

When Xu Gaofeng and his son made Jenny's spinning machine, Lu Chen had already ordered someone to collect wool.

"Grandpa, wool!" Hearing Lu Chen ask where the wool was, Xu Qizhi hurriedly brought a bag of wool over.

"Put it in! My father wants to try this weaving machine! Lu Chen motioned to Xu Qizhi to put the wool in the funnel.

"Grandpa, let the little ones do this kind of rough work!" Seeing that Lu Chen's posture was to be operated personally, Xu Gaofeng on the side hurriedly rushed to Lu Chen and said, mainly because although this thing was made according to the drawings given by his father-in-law, no one had seen and used it before, not to mention that this thing had to be hand-shaken, in case there was a mistake in one piece and his grandfather was injured, even if Lu Chen did not punish Xu Gaofeng, Xu Gaofeng would have to be scolded to death by the people on the Zhuangzi and beaten to death by his mother-in-law.

Now Lu Chen is in Lujiazhuang's heart, just like the immortals they worshipped before, if this hurts Lu Chen, Xu Gaofeng will never want to raise his head in his life.

"Will you?" Lu Chen glanced at Xu Gaofeng directly, Xu Gaofeng suddenly stayed in place, indeed, he and his son made this thing according to the drawings, but how to use it, I really don't know.

"That's it! I'll try it! It's okay! Lu Chen directly waved his hand and motioned Xu Qizhi to put the wool into the "funnel", Xu Qizhi poured some wool into it, and then Lu Chen began to shake the runner, at first the runner was still "crunching", after all, it had just been made, even if it was polished well, but in the final analysis, there was still no "running-in".

Listening to the tooth-sore "crunch" sound, everyone stared intently at the textile machine in front of Lu Chen, as the parts continued to run in, the "crunch" sound gradually weakened, and the wool in the "funnel" gradually decreased, with Lu Chen's shaking, the wool appeared.

Seeing the appearance of the wool, Lu Chen knew that the distance between himself and the woolen sweater was getting shorter and shorter, Lu Chen continued to try for a while, and then stopped, of course, with the appearance of the wool, the other people were naturally surprised, after all, the spinning wheel was one thread at a time, and the thing called "Jenny Weaving Machine" made by his grandfather could produce several threads at once, although he didn't know who this "Jenny" was, but it did not prevent them from worshiping Lu Chen.
