There is a process called Kraft pulping, which uses the interaction of caustic soda and odorous alkali to remove acidic lignin from the pulp.

Caustic soda is good to say, and now it is this kind of thing used to make soap, but stinky soda is more troublesome, and it has to be reduced by high-temperature burning of miscanthus nitrate and pulverized coal, and then treated with diluted alkali solution.

After Li Wei came to the newly established paper mill of the Ordnance Bureau, he asked the craftsmen to prepare things and start these things.

After personally operating it several times and verifying that this method is feasible, Li Wei taught the production steps in detail to several craftsmen he trusted.

Li Wei pointed to some white powder that had just been prepared and smelled of rotten eggs and said: "These are called stinky alkalis, and you will be responsible for making this thing in the future, remember not to get it on your skin!" ”

This thing will burn the skin when it gets on the skin, and in order to make this thing, Li Wei specially asked the pottery kiln to make protective glasses, as well as leather gloves, and he also sent these things to these craftsmen.

"Yes, sir."

Several craftsmen endured the stench, took the gloves and glasses distributed by Li Wei, and bowed down to reply.

Li Wei nodded slightly, handed over the work to them, and turned to leave.

With these two things, acid-free paper can be produced on a large scale.

And he doesn't plan to just produce acid-free paper, in this era, paper is also a very valuable thing, he can completely improve the papermaking process and sell paper to make money.

The huge amount of goods produced by the huge productive forces is the fundamental support for the value of money, and no other momentary manipulation can really solve the problem of currency depreciation.

In this era, it is impossible for him to go to the Middle East to grab oil, so he can only try his best to develop the manufacturing industry while printing new money.

After leaving the paper mill, he went to look at the painters who made the engravings, and now he just made some sample templates, and simply designed a few banknotes similar to those of later generations, and let these painters compare the engravings.

In order to improve the fineness of the engravings, he provided them with magnifying glasses and carving knives made of quenched high-carbon steel, which was made of soft and easy-to-work mild steel.

The engraving does not need to be as high-precision as that of later generations, as long as it is far ahead of the current process conditions.

When the metal engraving is ready, it is loaded onto a hydraulically driven roller, brushed with ink, and rolled through the middle of the large sheet of banknote paper, and the gravure is completed.

In addition to gravure printing, there are also watermarks that are pressed during the manufacturing process of banknote paper.

Acid-free paper, ink, gravure printing and watermarking, these technologies alone are enough to make people in this era desperate, and it is impossible to imitate counterfeit banknotes.

And the main thing is that this banknote is more resistant to wear and fold and is not easy to damage.

Li Wei inspected the various processes required for printing banknotes to ensure that there were no problems, and then he breathed a sigh of relief.

Now that you're ready, it's time to move on to the next step.

After leaving the Ordnance Bureau, he went to the Minghuang Chamber of Commerce and came to Fu and Shen Jing.

"How many goods are there in the Chamber of Commerce now?"

Li Wei asked directly.

"Master, I've already hoarded 500,000 pieces of all kinds of goods here!"

Laifu reported with a happy face.

Recently, due to the depreciation of treasure banknotes, prices have risen wildly, and the price of these various goods, which were originally 300,000 yuan, has risen to more than 600,000 yuan at this time.

Of course, now that the treasure money is depreciating, even if you earn these 300,000 yuan, it is only equivalent to less than 200,000 yuan last year, but most of these goods are taken on credit from Shen Bin's Wanshan Chamber of Commerce through those shopkeepers, which is equivalent to an empty glove white wolf, even if you give some benefits to those shopkeepers, it can also net more than 100,000 yuan.

Li Wei nodded slightly after listening to Laifu's words, and then looked at Shen Jing again.

"I've also stockpiled a lot of materials here, as well as our own goods, and if we sell them now, we can have about 400,000 yuan."

Shen Jing also looked relaxed and happy, since Li Wei drove away the eunuchs arranged by Wu Qi, his workshop is now better, although because of the leakage of the secret recipe, he is not making as much money as before, but it is much better than when he fed all the profits to those eunuchs before.

Both of them looked at Li Wei with happy and reverent eyes on their faces at this time.

This time, due to Li Wei's advance arrangement, they were lucky to avoid the depreciation of the treasure banknotes and exchanged most of the cash for physical goods, which have now nearly doubled. If it weren't for Li Wei's arrangement, the cash in their chamber of commerce would have depreciated by nearly half now.

Li Wei can be regarded as a big gamble this time, and now he not only basically spent all the working capital of the Minghuang Chamber of Commerce and hoarded all kinds of raw materials and goods for production, but also owed 300,000 yuan of goods to those shopkeepers on credit.

Of course, these shopkeepers are just passing hands, and Li Wei actually owes Shen Bin the money.

However, as the manager of the shopkeeper, if Li Wei can't pay back the money, then they won't be able to run, and Shen Bin will look for them at that time, not Li Wei.

If they know that the liquidity of the Minghuang Chamber of Commerce has bottomed out now, I am afraid that they will immediately come to the door to collect the debt.

Fortunately, they have always felt that the Minghuang Chamber of Commerce has a great cause, and they have not noticed these for the time being.

Li Wei pondered for a moment, feeling that it was almost the same now, and the ability of the Minghuang Chamber of Commerce was also limited, at most it could only go to this extent, and if he hoarded it again, he would have to borrow usury.

"In this way, from today onwards, we will ship slowly, and we will collect some treasure money first." Li Wei said softly.

"Okay."

Laifu immediately nodded in response, to be honest, he was already a little flustered at this point, and in two days, Li Wei couldn't help but take the initiative to ask for instructions if he didn't say anything.

Compared with Laifu, Shen Jing seemed to be indifferent, because he felt that the treasure money would continue to depreciate, and there was even a tendency to never look back.

But since Li Wei gave the order, he didn't force it, and then agreed.

"Remember to collect the old banknotes as much as possible when collecting money, the discount should be discounted, it is best to press down, and take all the old banknotes in our hands to the bank to exchange for new banknotes, and the old banknotes received from the shipment will also be reversed immediately!"

"Yes, sir!"

Li Wei instructed again and again to unfold his plans one by one.

The Minghuang Chamber of Commerce changed the image of Pixiu who used to only eat and not vomit, and began to ship out on a large scale, and the shopkeepers who secretly purchased goods from Shen Bin according to his instructions also immediately changed their doors and purchased goods from him, and a large number of treasure money quickly returned, and the business of the Minghuang Chamber of Commerce immediately became prosperous, and the faces of several people who knew about it, such as Shen Jing, were filled with smiles.

However, if some people rejoice, there will naturally be people who are worried.

In the central city of Jingshi, Shen Bin was in his own mansion, listening to the report of his shopkeeper, his face was mixed.

Since his father Shen Rong and eldest brother passed away one after another, as the third generation of the Shen family, he relied on the advantage of his elders to take away most of the family property from the hands of Shen Jing, the fourth generation of descendants, and replaced them in one fell swoop, becoming the third generation of the main line of their Shen family with the greatest wealth.

Originally, his nephew Shen Jing had always been so pressed by him that he couldn't raise his head, so he could only hold on to the remaining bit of family property to survive, and it wouldn't be long before he could annex the remaining shops and take over all the businesses of the Shen family.

However, just when he was about to succeed, Li Wei's accident appeared, Shen Jing found Li Wei and cooperated with the Minghuang Chamber of Commerce, and the shops in his hands that were already about to be unable to operate quickly came back to life, and as time went by, the business became more and more prosperous.

This incident made him extremely uncomfortable, and he immediately sent someone to inquire about the situation of the Minghuang Chamber of Commerce.

As a descendant of Shen Wansan, Shen Bin is still quite discerning in business, and after figuring out the origin and business model of the Minghuang Chamber of Commerce, he was immediately impressed!

This kind of business model of distributing goods has great potential, even if it is not to deal with his little nephew, he must also intervene! So he immediately followed the model of the Minghuang Chamber of Commerce and established the Wanshan Chamber of Commerce.

It's just that Li Wei is in a high position, and the Minghuang Chamber of Commerce has a royal signboard, so he has not dared to make a big move, so he can only follow behind and eat some clear soup and little water, until Li Wei is demoted.

During that time, he gave Wu Qi a lot of bribes, not only did he take the opportunity to take down the secret recipe for soap, perfume and other things through Wu Qi, but also took advantage of the relationship between Shen Jue, a cousin who was a member of the household department, in another branch of the Shen family, to get involved with some officials in the DPRK and China.

With the support of Wu Qi and these officials, he finally had the confidence to quickly seize a lot of business.

But this situation changed again after Li Wei became a concubine, Wu Qi directly cut off all contact with him, and many of those officials began to become unclear.

But his business has already done this, and he must not stop easily, so he can only grit his teeth and persevere.

However, to his surprise, after Li Wei returned, not only did he not rely on his power to suppress him, but many shops that originally cooperated with the Minghuang Chamber of Commerce also switched to his side, which made him both happy and worried.

"Master, the arrears of those stores have reached more than 500,000 yuan, do you think we should stop for a while, collect them and then supply them?"

A shopkeeper said with some concern.

Recently, the treasure money has continued to depreciate, and the price of goods has risen wildly, and even if the arrears outside can be recovered in full now, it will have to pay a lot, and he is a little worried that something big will happen if it goes on like this.

Shen Bin frowned when he heard this, he invested heavily in the Wanshan Chamber of Commerce, in order to grab some shops, he gave a longer amount of arrears and account periods, but with the depreciation of the treasure banknotes, these arrears have become a big problem, and the goods sold, when the money is recovered, the money is no longer valuable, and a lot of losses will be lost when it is in and out.

It's just that now that the stall is spreading, let him just give up, and he is a little reluctant.

His current situation is the same as those Internet companies that burned money to grab the market in later generations, the money has been burned, and the market that was finally grabbed is reluctant to give up, but if you want to keep it, you have to continue to burn, otherwise the Minghuang Chamber of Commerce will definitely grab it back immediately.

I'm sorry, I sent it so late, so I made everyone wait for a long time, friends who haven't slept, go to bed early after reading, good night
