"It's okay, it's okay, Manager Deng doesn't have to be nervous, Gu just thought of some interesting things."

Seeing that Deng Cheng was embarrassed, Li Xian suppressed his laughter and comforted him amiably, but the reason is really far-fetched, as for the real reason, it is easy to say, that is, Li Xian has completely concluded that this is the real ancients in front of him, not the Xibei goods that have crossed over - when he was wandering around in the Zhuangzi before, Li Xian had found that this "ecological farm" lacked such an element as a biogas digester, and now he is tempted again, Seeing that Deng Cheng had never heard of such a thing as biogas, he could naturally make up his mind - the discoverer of biogas was the Italian physicist Volta at the end of the eighteenth century, and the first practical biogas digester was invented by the French in the nineteenth century, and it was introduced to China at the beginning of the twentieth century. The biogas digester is the key to the key, only by building the biogas digester, the effect of the entire farm can be maximized, obviously, this Deng Cheng does not know, so the answer is about to come out.

"Your Highness, what is that swamp, what is methane?"

Deng Cheng is obviously a good person to study and has a lot of curiosity, and when he saw Li Xian's kind attitude, he also had the courage to ask.

"Well, Steward Deng has ever found that the pool where you hoard manure often bubbles, and the smell is slightly smelly, if you put it on fire, it will be able to ignite, and this gas is biogas."

The composition of biogas is complex, and it is not easy to explain, and Li Xian is not easy to bring out the modern chemical system, so he can only mention it superficially.

"Ah, it's this thing, the subordinates know, a few years ago, there were children in the village playing with fire by the manure tank, and it was dangerous to cause a big disaster, the subordinates felt strange at the time, but I don't know why, now I heard His Royal Highness say this, but I understand a little, but this gas is diffuse, how can it be used?" As soon as Li Xian said this, Deng Cheng suddenly realized, but then frowned again, and he didn't know how to use biogas.

"This matter has been seen in the previous person's codex, but has never seen the real thing, it has been a long time, and Lone is a little unclear, so I will look back and check it." The principle and design of the biogas digester are not difficult, Li Xian personally supervised the construction when he was a township official in later generations, and he knew that even if there were no steel pipes, valves and other things at this time, Li Xian could also come up with a set of alternatives, but if he really wanted to explain it clearly, it was not possible to do it in a few words, Li Xian didn't want to bother with that tongue, besides, although the biogas digester was a good thing, compared to Li Xian's plot to come, it was not worth mentioning at all, and he didn't want to be entangled in such trivial matters, so he casually found an excuse to shirk it. Then, without waiting for Deng Cheng to react, he changed the topic: "I heard that Steward Deng had been in business all over the world, and Yu Shang must be proficient in it. ”

"Don't dare, Your Highness has something to order, and your subordinates should do their best."

Deng Cheng was thinking about the method of using biogas, and suddenly saw Li Xian change the topic, he was stunned for a moment, and then hurriedly bowed down and answered.

"Hmm, if Lone gives you a sum of money, thinking that it is for business, how much can you get in the annuity?" Li Xianyi raised his eyebrows and asked in a deep voice.

"If you go back to Your Highness, it depends on the size of the principal, there are big usages, and small places to go, so it's hard to make a conclusion."

As soon as he heard Li Xian ask such a question, Deng Cheng's eyes lit up, and he had vaguely guessed the true intention of Li Xian's "Cake Village", and his spirit was suddenly lifted, and he replied aloud without thinking.

"Oh, that's right, how can you go if it's forty times?"

Li Xian nodded with a smile and gave a restriction.

"If according to this number, the north and south sell goods, a year back and forth, or can make twice as much profit, if the situation is good, five times is also possible, and more, then it must be lucky, if the judgment is wrong, it is not uncommon to lose all the money." After thinking about it, Deng Cheng replied in a calm tone.

"Oh? What if it's 400? Li Xian smiled noncommittally and expanded the amount tenfold at once.

"If there is this number, the choice will be several times larger, safe some can open a shop, subordinates have operated silk, this amount to open a silk village is barely enough, if the business is successful, the whole year may be more than three times more profitable, if it is combined with people to form a caravan, walking in the Western Regions, a back and forth need to get more than two years, the profit can be ten times, but the road is difficult, the road is uneven, success or failure is difficult to reverse, as for other livelihoods, such as restaurants, restaurants, etc., or can be stable, but there is no windfall at all."

Four hundred is not a small number, but it is not too amazing, if you take it as a business, it can only be regarded as a medium to small scale, and a business of this scale is the most difficult to operate, it is difficult to do a big business, and it is too wasteful to do a small business, even if Deng Cheng is good at business, he did not dare to answer easily, but pondered for a moment, and then opened his mouth cautiously.

"Well, what if it's 40,000?"

Li Xian had contact with business when he mixed officialdom in later generations, but he just knew that he didn't know why, of course, the concept of business was advanced enough, at least he couldn't be regarded as a layman, even if he was not familiar with the business of this era, but the basic judgment ability was still not lacking, just listen to it and know that what Deng Cheng said was not a lie, but Li Xian did not have any expression, but quietly raised the amount to an astronomical amount.

"Forty thousand?"

As soon as he heard such an astonishing number, Deng Cheng's body trembled obviously, looked at Li Xian in disbelief, and muttered hesitantly.

"Yes, if there are 40,000 guan, how will Steward Deng use it?" Li Xian smiled slightly and replied affirmatively.

"This ......" Deng Cheng was stunned, and after his face changed a few times, he shook his head with a wry smile and said: "Your Highness Haihan, my subordinates have never calculated so much principal, and I really don't have the slightest certainty about it. ”

"Oh? Hahaha......" As soon as Li Xian heard this, he couldn't help but laugh out loud.

"Your Highness forgives your sins, subordinates, subordinates ......"

Seeing Li Xian smiling happily, Deng Cheng couldn't help but feel a little embarrassed, with a bitter face, and didn't know what to say.

"It's okay, Steward Deng is really a sincere person, good, very good."

The more the principal, the better, especially when the ability to control so much money is not yet available, it often either causes a backlog of capital and wastes, or it leads to a total loss due to extravagance, this truth Li Xian is naturally very clear, and he will not be disappointed because of Deng's honesty, but he appreciates his ability a little more, so he praised it with a smile.

"Your Highness has won a false award, and your subordinates are ashamed." As soon as he heard Li Xian say this, Deng Cheng hurriedly thanked him, but his eyes flashed with anticipation and longing, and there was a bit of nervousness in his heart.

"Steward Deng doesn't have to be nervous, Lone doesn't have 40,000 yuan of principal to play with, well, it's only 200 yuan, but Lone has to recover 5,000 yuan a year, can Manager Deng do it?" Deng Cheng's face changed, Li Xianzi saw it all in his eyes, his heart was happy, he laughed playfully, and asked jokingly.

"Ah, five thousand? This ......"

Deng Cheng was shrewd, guessing that Li Xian was here to do business, and he was looking forward to it, but he never expected Li Xian to make such a ridiculous request, and he was dumbfounded for a while, looking at Li Xian dumbfounded, and couldn't understand whether his little master was making fun of himself.

"Five thousand guan is only the first year, from the second year, if this number can't be doubled, then it is considered a failure, can Steward Deng understand?" Without waiting for Deng Cheng to react, Li Xian smiled, and then put forward an even more outrageous request.

"Ah......h

Dumbfounded, Deng Cheng was really dumbfounded, his mouth was so wide that he could almost stuff a duck pear, and the sweat on his face was surging like a waterfall, and after being stunned for a long time, he raised his hand, wiped his sweat with his sleeve, and said with a bitter face: "Your Highness forgives your sin, your subordinates and subordinates are incompetent, you really don't dare to accept it, and please ask Your Highness Haihan to be one." ”

Gotta not tease you! Seeing Deng Cheng embarrassed like this, Li Xian couldn't help laughing, laughing so that Deng Cheng was even more frightened, after a long burst of wild laughter, Li Xian said with a solemn face: "Lonely is not a foolish person, dare to say this, there is a reason for loneliness, Deng only needs to do things with a solid heart, there is no reason, there are some gadgets here alone, you just have to do it." As he spoke, Li Xian took out a letter from his arms, weighed it in his hand, and then stretched it out to Deng Cheng.

"This, this is ......"

Deng Cheng took the letter with a puzzled face, opened it and saw that there were more than a dozen thick pages inside, not only with drawings on it, but also text descriptions, but Deng Cheng couldn't recognize what those things were, frowned and thought for a long time, but he still couldn't help it, so he had to look at Li Xian, hissing and asking.

"There are four things here, one is a folding fan, with poems, calligraphy and paintings, which is a good tool for scribes to show their grace; the second is the distillation tower, which can purify the light rice wine and make fine wine; the third is soap, which is the most suitable for washing; Fourth, for the first time, can make firecrackers, flowers, for the festive use, there are these four things, why worry about the business road is not open, today has become hotter, just take the folding fan as the beginning, give a month alone, be sure to make the folding fan first, as for the market, alone has its own opinion, can Deng Guan do it? Li Xian casually explained the four things, and then made a request.

"If there are 400 pieces of use, the subordinates can barely give it a try."

Seeing that Li Xian had already said this, Deng Cheng didn't dare to slack off, and after thinking about it carefully, he gritted his teeth and agreed.

"Well, that's good, lonely ......"

Seeing that Deng Cheng was so cautious, Li Xian admired it very much, and was just about to open his mouth to say a few more words of comfort, when he suddenly saw Gao Miao hurriedly entering from outside the door, his face seemed to be unpleasant, and he couldn't help but be stunned, and stopped halfway through the words, frowning suspiciously......
