Chapter 448 Test Firing

This gave rise to the issue of taxation. The tax code of the Song Dynasty looked very friendly, but in actual implementation it was not.

Suyou has copied the taxation system for road transport from Meishan to Chengdu. There is no reason why the taxation system is smooth for the land route, while the waterway is still being blocked.

Only seat taxes are collected at the place of delivery, and line taxes are collected at the place of receipt. Only invoices are checked along the way, and no exorbitant taxes or miscellaneous taxes are allowed.

There are only three ways to gain local income. One is to develop production and become a source of high-quality products; the other is to provide good services so that thousands of merchants gather, cars and ships to stay; third, welcome to join the ranks of commodity transportation and pull goods out.

Make other people's money.

At the same time, merchants whose assets exceed a certain amount can open an account with a bank, so that in addition to interest, they will also get various conveniences, such as paying taxes and being able to transfer them directly to the account.

Of course, more is the transfer between merchant accounts. In the entire Xiajiang Economic Belt, this method of capital turnover has become the norm.

With the development of the upper reaches of the Yangtze River today, it has become the most economically active area in the Song Dynasty. Many businessmen have set their sights on the middle and lower reaches of the Yangtze River, where there is still a large amount of fertile undeveloped land and a large number of lakes rich in aquatic products.

and swamp.

After the ship passed Luzhou, Zhang Qi, who had always been forgetful, fell ill.

Su You didn't take it seriously at first, and laughed: "You have been living in Qingtang for so long, but you are not used to it when you return to your hometown?"

Shi Wei has now changed her hair style and put her hair in a bun. She has shed a lot of her childishness and is more bright and attractive. She stepped forward to measure her body temperature with a thermometer, looked at it carefully, and found out that she was suffering from miasma.

I was prescribed Qingsan medicine to relieve symptoms, but my condition worsened that night. First, I felt weak and yawned, then shivered, and then developed a fever and headache, and the cycle continued.

Su You was also a little panicked now. This was a pretense, malaria!

Asked: "Did you get bitten by a mosquito?"

Zhang Qi said feebly: "It was hot the past few days, and I wanted to cool off, so I dragged a cooler on the deck and slept for a few nights, and smoked mosquito repellent..."

Su You rolled his eyes: "The river is so vast, how much use can one piece of incense do?"

Shi Wei smiled and said: "It's okay, Brother Xiaoqi will still have to suffer for two days. This is Ziwu Miasma, Changshan, Shuqi, Areca, and Pinellia. There are ready-made prescriptions. Add or subtract as appropriate. Brother Xiaoqi will be here in two days.

It’s alive and kicking again.”

Speaking of this, Su You felt that he had the right to speak: "Can the combination of these four herbs be more effective than Artemisia annua?"

Shi Wei smiled and said: "Actually, it can be regarded as three flavors. Shuqi is actually a seedling from Changshan Mountain. The artemisia annua you mentioned should actually be Huanghao, but the recipe requires a large dose and requires a lot of fresh grass.

It’s too troublesome to take the juice and have to take it continuously, so I’d better use a prescription.”

After the medicine was boiled and given to Zhang Qi, Su You murmured to Shi Wei: "I don't know how the microscope research at Daxiangguo Temple is going..."

The great monk Daolong of Daxiangguo Temple once preached to Su You, and then said that "Buddhism sees eighty-four thousand insects in a bowl of water."

At that time, Su You despised him and said that everyone in the world could see without Buddha's eyes.

The two made a bet. If Suyou could do it, Daxiangguo Temple would allow Sitong Company to open a pickle counter in Daxiangguo Temple for free.

He's a bastard but doesn't take advantage of it. With experience in telescopes, Su You and Shi Tong soon came up with a microscope with knobs and a light-filling plate.

Monk Daolong is very grateful, Su Tanhua is really a scholar of heaven and a man who understands the good way. The pickle counter of Daxiangguo Temple will be yours without any problem.

When the second gathering of all surnames was held, the great monk Daolong brought out the microscope, and the dignitaries of Bianjing rushed to see it. It turned out that there were so many small insects in the clear water in the Buddha's eyes!

The Buddha really did not lie to us!

Since then, this has become a traditional show-off project in Daxiangguo Temple. Every time there is a gathering of Wan surnames, the monks are lenient when collecting incense money.

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

Su You regretted it so much that he couldn't help stamping his feet when he found out. How had he ever won when dealing with Monk Daolong?! The Ma Dan microscope was sold cheaply!

However, the great monk fell into a problem and did not dare to drink water.

In the end, Su You gave the elder monk a set of filtration equipment for raising goldfish for his younger sister. After the elder monk observed the 18-layer filtered water with a microscope, he expressed his gratitude: "Tanhua Lang really saved the old monk's life."

Skin."

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

Making ether is actually very simple. You can get it by dropping hot alcohol into nitric acid and condensing the steam.

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

This thing is very useful. It is a perfect extraction agent for various organic oils, dyes, alkaloids, resins, nitrocellulose, spices, and medicines. At the same time, it can also provide anesthesia and perform surgery.

With it, artemisinin is no longer a problem.

Artemisinin plus mosquito nets, coupled with clean drinking water habits, the existing epidemic prevention measures can actually prevent and treat the so-called miasma in many areas.

Today's Pengli Dongting, many areas are still a wild animal kingdom where mosquitoes are rampant and crocodiles are infested. If Jinghu Lake is to be developed in the future, artemisinin is an indispensable life guarantee.

There is also incense. With ether, aromatic substances can be extracted from a variety of flowers and plants, mixed with alcohol, and dyed to create perfume. Even in later generations, it was a huge profit industry.

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

The ship soon passed 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.

The last time I answered questions every day, I was not in the mood to travel. Now looking at Su Yuanzhen who was madly answering questions in the back room, Su You said to Shi Wei that people are not saints, and sometimes one's own happiness is indeed based on the pain of others.

above.

Zhong Yi's ballistae control skills are already quite impressive. The child's practical progress is far better than the accumulation of mathematical knowledge. After aiming with his fingers, parameter conversion is carried out quickly in his mind, and his mental arithmetic ability is now top-notch.

Su You was going to find a remote place to try.

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

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

Everyone on the boat gathered around to see the strange thing.

Zhong Yi adjusted the ballista: "Teacher, that's it."

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

The porcelain bullet is in the shape of a water drop, and at the end of the water drop, there are four tail pieces made of thin wood.

There is a hole on the drop head, and a brass nut is glued with glue paint.

Su You opened another box and found a tube inside. At one end of the tube was a bright red hemisphere.

Su You pulled out the pin under the hemisphere, carefully inserted the pipe into the nut, and then tightened it.

Confirming that it was correct, Su You stood up and put his eyes on the theodolite beside the ballista: "Thirty-five meters ahead, the target is the big stone cow, let go!"

Zhong Yi pulled the trigger, and with a "boom" sound, the white porcelain bullet drew a beautiful parabola in the air, and with 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 the blink of an eye, followed by a loud "bang" sound, forming a huge echo in the mountain gorge.

The dusk bird flew away in fright, and the rocks, porcelain pieces, and mud exploded by the porcelain bomb flew into the air in a fan shape.

Immediately afterwards, it was like a hail of mud, falling in the bay in front of Shi Niu, covering an area of ​​more than ten meters.

A stone pit appeared at the feet of the big stone cow, and a piece of mud rolled up around it, making the already not clear river water even more turbid.

Su You estimated that the killing radius of this porcelain bomb was about five meters, and it was quite powerful.

The thick smell of gunpowder smoke floated along the river bay, and everyone was stunned. Only Zhong Yi and Su You jumped up and high-fived: "Yeah! Success!"

Zhong Yi still has more to say: "Teacher, how about two more?! It's so enjoyable!"

Su You rolled his eyes: "You are so beautiful, do you know how much one of them costs? The light jade porcelain practice bullets cost hundreds of renminbi! From now on, I can only play with that, and I have to shoot straw targets on the lawn and try to recycle them!"
