The benefits and opportunities contained here are simply too great. This is not only comparable to the two Zhejiang Roads, this is basically a trade circle that controls half of the world.

No matter how gentle Su Shaobao operates and takes into account the interests of all parties, Da Song will always get the absolute majority.

The annual fiscal revenue of the Song Dynasty was more than 100 million guan. After Su You's 25 years of hard work, it has now quietly increased to 160 million guan, of which 100 million guan came from Shuzhong (including Dali), Bianjing, and Liangzhou.

Zhejiang, and if it continues to develop according to Jiangsu Oil's plan, it should not be a problem to exceed 200 million yuan in a few years.

The substantial improvement in the financial situation allowed the Song Dynasty to do more things. The completion of the reinforcement of Bianjing City was a strong signal.

This is not a simple project. The renovated Bianjing city wall spans fifty miles in circumference. Each city wall is supported by twenty reinforced concrete forts. Each fort has two country-defending general cannons. When equipped with new ammunition, the range

Able to reach eight miles!

With them and the new army, Bianjing City no longer needs 400,000 troops to defend it, a mere 40,000 people are enough!

The huge cancer attached to the finances of the Song Dynasty, the redundant army, will be removed by the major transformation of the capital.

But until now Su You is still holding on. As long as things develop in that direction, no one in the court is a fool, and sooner or later someone will see this step.

So now he is taking advantage of the rainy season to patrol leisurely, which is equivalent to giving himself a holiday. After inspecting Jiaozhou, he went to Yezhou again.

In the huge dry dock of Yezhou Shipyard, four huge Hangzhou-type schooners are being maintained and renovated.

It’s time to eat oysters again.

Zhao Zongyou is an otaku and has no interest at all in the colorful world of Yunzhou City opposite Halong Bay.

The purpose of this exploration was still not to complete the circular exploration of Southern Songzhou. Zhao Zongyou arrived at Mingzu Island, stationed a fresh force for the team members, and sent a large amount of supplies, craftsmen, livestock, engineering machinery, axes and saws, experimental equipment, and observations.

After setting up the equipment, the sail started to the west of Mingzu Island and along the coastline.

However, his luck was not as good as Shao Bowen's. There were deserts and red rock beaches all the way, but the depth of the water seemed to be more conducive to navigation.

I carried a lot of supplies, so I didn’t need to worry, so I surveyed and measured all the way. The wind was strong and the sailing was fast.

The entire western front is almost a wilderness area with no human habitation and relatively dry conditions. It was not until we passed the most prominent part of the west that the situation began to improve.

A large number of the wild animals sketched by Shao Bowen's reporter team were also found here, as well as patches of huge eucalyptus forests, where a cute little bear that poops in cubes lives and lives by eating eucalyptus leaves.

The more he measured, the more terrifying he found this place. From the golden beach in the east where Shao Bowen measured to the west where he finally arrived, the area at 2 degrees 52 minutes east longitude and 31 degrees 52 minutes south latitude was all black.

The length of the Swan River Estuary and the measured coastline exceeds tens of thousands of kilometers!

This river is the most suitable place to live in the entire western part of Southern Song Dynasty. Because of the black swans that have never been seen before, Zhao Zongyou named it Xuanhu River, and also set up an observation camp on the Jiangwan Highlands, named

It is Xuanhu City.

This is Perth in real history.

He ordered his sergeants to build a wooden walled city at the mouth of the river. When Zhao Zongyou was exploring the inland river, he discovered that a beach along a riverside stream was full of shimmering sand gold.

There must be a huge gold mine upstream here.

But Zhao Zongyou made a mistake, Shao Bowen left in a hurry, and the information did not mention this - it is winter in the southern hemisphere!

What makes me angry is that I didn't think of this. This should be inferred!

Fortunately, apart from the strong wind, the climate here is very livable and the winter is not freezing.

Zhao Zongyou hurried back to Xuanhu City, slaughtered the sheep to get their skins, bought a pair of wallets and jackets for the soldiers left behind, and left enough supplies before returning home as soon as the weather was okay.

On Mingzu Island, he also presided over the completion of the observatory, smelting blast furnace, lime kiln, pottery kiln, and coke oven, renovated the military camp, village walls, and warehouses, built the bay trestle, and designed the breakwater. After completing many of them, he left three

Hundreds of troops were stationed to protect the base before returning to Yezhou.

The materials and equipment brought by this voyage are terrifying. The royal family is very wealthy, so it is just right. The three large ships can be used to transport various metal ingots on the Jiaozhi Road.

Su You walked into the design office of Yezhou Shipbuilding Department, followed by Zhang Qi, carrying a basket full of big oysters in his hand.

"What are you doing?" Su You general Zhao Zongyou was studying the drawings there: "Relax and relax when you come back, don't study hard every day."

Zhao Zongyou put the pencil on the table: "Jingrun's design triples the power of the steam engine. It can basically be put into large-scale use and can be used as a power source."

"Look, Grand Master, Zhengzhou and Yunzhou encountered floods this year and suffered heavy losses. What's the reason? Isn't it because most of the workshops rely on water energy and can only be built near the water, making it difficult to withstand a big flood?"

"If this machine can be enlarged, can it replace water power? In this case, the workshop will no longer be restricted by location and can be installed anywhere in the Song Dynasty!"

"Also, every time you cross the equatorial windless zone, you have to wait until December or June when the winds are strongest. It is still too slow. If a steam engine is used as power, can the ship be pushed through the windless zone?

"

"Can you look at the blueprint of the ship I designed?"

Su You took the drawing over and saw that it was a schooner with two huge paddle wheels hanging on both sides.

Su You nodded: "You are stealing the design of my fish pond oxygen supply device. In fact, there is a problem. When the sea wind is strong, the wind will cause huge resistance to the wheels, which will cause the steam engine to be unable to push under the existing power.

Turn the wheel.”

Zhao Zongyou took a piece of paper and started calculating. After the calculation, he threw the pen on the paper: "It's true, if the wind speed exceeds four meters per second, the wheels will not turn."

Su You said: "Also, the force of waves on the wheels will also affect the stability of the ship, leading to the risk of capsizing."

Zhao Zongyou nodded: "It seems that you have already thought about this problem. What is your plan?"

Su You brought Zhao Zongyou to the laboratory, opened the drawer and took out a small boat.

There is a rubber band in the middle of the boat, connected to a brass shaft, and the tail of the brass shaft is connected to a small three-petal flower-like thing at the stern of the hull.

Turning the little flower with his fingers and tightening the rubber band, Su You put the boat in the water tank. As soon as he let go, the small flower started turning and the boat drove towards the front of the water tank.

Zhao Zongyou's eyes lit up: "Wonderful!"

He took out the model from the water tank and glanced at the tail: "Is this...the principle of the equidistant spiral water pump?"

Su You smiled and said: "Sure enough, it is not difficult to understand. It is exactly the principle of equidistant spiral. Since it can draw water, if it is turned in the opposite direction, of course it can push water."

"Not bad, not bad." Zhao Zongyou was full of praise: "This completely solves the problem of the paddle wheel."

"This part is called a propeller." Su You took out some more drawings from the drawer: "These are some plans I imagined for your reference. This thing is mainly difficult to design. It is difficult to actually process it. Use wax molds and

The lost wax method can be obtained by casting bronze or brass."

Zhao Zongyou nodded: "I also discovered during this voyage that copperware is not easy to attract those nasty creatures."

Su You pulled Zhao Zongyou out: "Haha, if you didn't mention Jiedu, you would have forgotten it. Those guys are not annoying, they are delicious!"

I took out a blowtorch and a thin copper basin from the laboratory. I put it on the suyou table and used it as a pot. I took out the knife from my schoolbag and broke open the oyster shell. I took out a mortar, washed it and poured in the minced garlic, soy sauce, oyster sauce, and tea.

Oil

Mix them together to make a seasoning, put the empty oyster shells on the bottom of the basin, add water, put the shells with oyster meat on top, use a glass spoon for experiments to apply the seasoning on the oyster meat, and then find a copper basin.

Turn upside down and steam.

Zhao Zongyou was stunned: "Why do you have these things in your bag?"

Su You said: "I came here specifically to eat oysters today."
Chapter completed!
