Chapter 448: Test firing

This creates the problem of taxation, which looks very amiable in the tax code of the Great Song Dynasty, but is not so in practice.

Su You copied the tax system for road transportation from Meishan to Chengdu, and there is no reason why the tax system is smooth on land, and the waterway is still eaten and asked for by cards.

Only the tax is collected at the place of delivery, and the tax is collected at the place of receipt, and only the quotation is checked along the road, and no exorbitant taxes are allowed.

There are only three ways for the local government to obtain income, one is to develop production and become a source of excellent products; the second is to do a good job in service, and thousands of merchants gather vehicles and ships to stay; Three, welcome to join the ranks of commodity transportation, pull out the goods to make other people's money.

At the same time, merchants with assets exceeding a certain amount can open an account in the bank, so that in addition to interest, they will also get various conveniences, such as paying taxes, which can be transferred directly on the account.

Of course, more is the transfer between merchant accounts, and in the entire Xiajiang Economic Belt, such a way of capital turnover has become the norm.

The upper reaches of the Yangtze River have developed to this day, and have become the most economically active area in the Great Song Dynasty, and the eyes of many businessmen have been put into the middle and lower reaches of the Yangtze River, where there is still a large amount of fertile undeveloped land, as well as a large number of lakes and swamps rich in aquatic products.

The boat passed through Luzhou, and Zhang Qi, who had always been mentally forgetful, fell ill.

At first, Su You didn't care, and sneered: "I've been in Qingtang for so long, but I can't adapt to the soil when I go back to my hometown?" ”

Shi Wei has now changed her hairstyle, put her hair in a bun, taken off a lot of childishness, and is more bright and moving.

I drank the antidote medicine that I was prescribed, but my condition worsened that night, first I was tired and yawned, then I shivered, and after a while, I had a fever and headache, and the cycle continued.

Now Su You is also a little panicked, this is a swing, malaria!

Asked, "Are you bitten by a mosquito?" ”

Zhang Qi said weakly: "A few days ago, it was hot, and I was greedy for coolness, so I dragged the cool board and slept on the deck for a few nights, and smoked mosquito repellent coils......"

Su You rolled his eyes: "The river is so open, how much can a stick of incense be used?" ”

Shi Wei smiled: "It's okay, it's just that Little Seventh Brother will suffer for two more days." This is the meridian miasma, Changshan, Shu lacquer, betel nut, there are ready-made recipes in Banxia, add or subtract as appropriate, and two days later, the little seventh brother will be alive again. ”

Speaking of this, Su You felt that he had a very right to speak: "The compatibility of these four herbs can be more effective than Artemisia annua?" ”

Shi Wei said with a smile: "Actually, it's okay to count three flavors, Shu paint is actually the seedling of Changshan." The Artemisia annua you are talking about should actually be Artemisia annua, but to use that recipe, the dosage is very large, you need a lot of fresh grass juice to take, and you have to take it continuously, it's too troublesome, so let's use the prescription. ”

After the medicine was boiled and Zhang Qi took it, Su You muttered to Shi Wei: "I don't know how the microscope research of Daxiangguo Temple is......

The great monk Daolong of Daxiangguo Temple, once said the Dharma with Su You, and then talked about "Buddha view a bowl of water, 84,000 insects." ”

At that time, Su You despised it, saying that there was no need for Buddha's eyes, and everyone in the world could see it.

The two made a bet that if Su You could do it, Daxiangguo Temple would allow Sitong to open a pickle counter in Daxiangguo Temple, free of charge.

If you have a cheap advantage, you don't take advantage of it, that's a bastard. With the experience of a telescope, Su You and Shi Tong soon came up with a microscope with knobs and a fill light plate.

Daolong Monk Heshi praised, Su Tanhua is really a pedantic heaven and a man who is enlightened and good, and the pickle counter of Daxiangguo Temple, no problem belongs to you.

When it came to the second gathering of ten thousand surnames, the great monk Daolong moved the microscope out, and the dignitaries of Bianjing competed to watch, and it turned out that there were so many small insects in the clear water in the eyes of the Buddha!

The Buddha didn't lie to us!

Since then, this has become a traditional pretending project of Daxiangguo Temple, every time the surname is gathered, the incense money is received by the monks.

Not to mention the rent of a pickle counter, a hundred are earned back!

Su You couldn't help but stomp his feet when he knew that he regretted it, and when he dealt with Monk Daolong, which time did he win?! The hemp egg microscope is sold cheaply!

However, the great monk fell into a problem and didn't dare to drink water.

In the end, Su You sent a set of filtering equipment for the little sister to raise goldfish to the great monk, and after the monk observed the eighteen layers of filtered water with a microscope, he thanked him: "Tanhualang really saved the old monk's skin." ”

Zhang Qi's malaria reminded Su You that it was time to get the ether out.

Ether is actually very simple to make, hot alcohol is dropped with nitric acid and the vapor is condensed.

Nowadays, with glass containers, with alcohol and nitric acid, there is no difficulty at all.

It is useful as a perfect extractor for various organic oils, dyes, alkaloids, resins, nitrocelluloses, fragrances, medicines, and can also be used for anesthesia and surgery.

With it, artemisinin is no longer a problem.

Artemisinin plus mosquito nets, combined with clean drinking water habits, the existing epidemic prevention measures, in fact, the so-called miasma in many areas, can already be prevented.

Today's Pengli Dongting, many areas are still mosquito-infested, crocodiles-infested wildlife kingdom, to develop Jinghu Lake in the future, artemisinin is an indispensable life guarantee.

There is also playing with incense, with ether, you can extract aromatic substances from a variety of flowers and plants, mix and add alcohol, and after dyeing, it is perfume, even in later generations, it is a profiteering industry.

In addition, the Meishan dye processing industry should also be upgraded.

The ship soon passed through Yuzhou and began to cross the Three Gorges.

This is Su You's second trip to the Three Gorges, but his mood is completely different.

Last time, I brushed the questions every day, where was I in the mood to travel, and now looking at Su Yuanzhen who was frantically brushing the questions in the room behind the cabin, Su You said to Shi Wei that people are not sages, and sometimes their own happiness is indeed based on the pain of others.

Chongyi's ballista control technology is already quite good, the progress of this baby's practical operation is far better than the accumulation of mathematical knowledge, after the finger aiming, the parameter conversion is carried out quickly in the brain, and the mental arithmetic ability is now first-class.

Su You is ready to find a remote place to try.

That night, the ship docked in a large bay, a tributary.

At the other end of the bay, there is a river stone in the water, as big as a cattle.

Everyone on the boat gathered around to see the surprise.

Chongyi adjusted the ballista: "Teacher, it's okay." ”

Su You put on gloves and took out a white porcelain bullet from the oilcloth box.

The porcelain bullet is drop-shaped, and at the end of the droplet, there are four pieces of thin wood made of tail.

There is a hollow in the dripper head, and a brass nut is glued with glue.

Su You opened another box, and there was a tube inside, and at one end of the tube was a bright red hemisphere.

Su You pulls out the pin under the hemisphere, carefully inserts the tube into the nut, and then tightens.

Sure, Su You stood up and put his eyes on the theodolite next to the ballista: "Thirty-five meters ahead, the target is a big stone cow, put it!" ”

As soon as Chongyi pulled the trigger, with a "boom", the white porcelain bullet drew a beautiful parabola in the air, and under the stability of the tail, it fell towards the big stone cow.

Everyone watched as a small white dot landed at the feet of the stone cow in a blink of an eye, and then there was a loud "boom", forming a huge layer of echoes in the mountain gorge.

The twilight birds flew in fright, and the stones, porcelain pieces, and silt blown up by the porcelain bombs flew into the air in a fan shape.

Immediately after that, like a hailstorm, it fell in the bay in front of the stone ox, covering an area of more than ten meters.

At the feet of the big stone ox, a stone pit appeared, and a piece of silt rose around it, staining the already not clear river water even more turbid.

Su You estimated that the killing radius of this porcelain bullet should be about five meters, and the power can be described as quite powerful.

The thick smell of gunpowder smoke wafted along the river, and everyone was dumbfounded, only Chongyi and Su You jumped up and high-fived: "Also!" It worked! ”

The friendship is still unfinished: "Teacher, do you want to come again?!" It's so enjoyable! ”

Su You rolled his eyes: "It's so beautiful that you know how much it costs?" The light jade porcelain practice bullet is hundreds of texts! In the future, I can only play that, and I have to hit the straw target on the lawn and try to recycle it as much as possible! ”

After speaking, he pointed to the white belly that was turned up by the stone cow, and the large and small fish floating over with the river: "Hurry up and catch it!" There's fish to eat tonight! ”
