At this moment, on the distant sea, ten sea ships are heading towards their destination, above the sea, the temperature is quite moderate, and the boatmen outside the cabin have already taken off their clothes and bare their chests and backs.

In the cabin, Wuyongzi leisurely held a fan and sat on a rocking chair, very leisurely. Wan Song closed his eyes and recuperated, the bumps on the ocean for more than a month, Wan Song didn't know how many times he vomited, but fortunately, Wu Yongzi knew some medical skills, and carried some seasickness medicine with him to relieve Wan Song's seasickness symptoms.

At this moment, the hired man on the bow of the ship at the front had already seen a piece of land in front of him, and he ran into the cabin while cheering, and said breathlessly: "General Wan, Dao Chief, good news!" There's a place ahead—"

"Oh, really!" Then Wan Song and Wu Yongzi went out of the cabin together, and saw that there was a harbor in the distance, and it was getting closer and closer, and then looked at the map, it was indeed here, and this place was the Keelung Port in the future.

"This must be the port marked on the map!"

Everyone on board was very happy, and after a few days of exploration, they finally saw the unfamiliar mainland, and this is the northern end of Liuqiu [the northeast corner of Taiwan].

Soon after, ten ships entered the port, which is a natural harbor, surrounded by mountains on three sides and facing the sea on one side, and the mountains here are shaped like chicken coops, which is quite hot.

Wu Yongzi's poisonous eyes have clearly seen the importance of this port in the Great Song Dynasty in the future, and Zhao Dezhao clearly wrote the word "Keelung" on the map, presumably His Royal Highness already has it in his heart, and it can be used as a major port in the future.

When the ship docks, the soldiers of the forbidden army on board first get off the ship to find out the surrounding situation, and if there is no danger, then the personnel on board can disembark. The soldiers of the Forbidden Army probed for a while, and found that there was no situation around, and there were no people, so all the people on board disembarked.

Everyone got off the boat and began to observe the topography of this place, which is a hilly area, and there is a harbor, surrounded by mountains on three sides, ancient wood jungles, distant mountains and green, and clear water in the distance. Strange flowers bloom in the forest, and the young willows dance with golden silk on the ground. Basically, it is concluded that there is a possibility of no human settlement. With the crude map drawn by Zhao Dezhao, everyone soon found that there was a river meandering on it, and the group walked up the river.

On the waterfall of the stream, the spring water dingdong, everyone groped the road ahead, constantly waved the firewood knife in their hands, poked out a road, and along the way can see all kinds of snakes, insects, rats and ants, it is really a natural and primitive taste.

The group walked for a long time with tools, food and other equipment, and camped on the top of the mountain for the night, and the next day they saw the target they were looking for on the map.

In front of him is a mountain, this mountain faces the sea, the valley overlaps, the water is wide and peaceful, the valley crosses, this place to the south is hilly, the terrain is not precipitous, and Wan Song, Wu Yongzi they stand on a flat stall, and then everyone began to cut down trees and collect wages, clean up the wasteland, and at sunset, build five houses.

At night, the sky in Keelung is full of stars, and the five rooms on the ground are lit up.

Inside the house, Wan Song picked up the wine glass and toasted: "Thanks to all of you, everyone came here together, let us open up this land in the future and expand the territory for my Great Song Dynasty." Thank you for this glass of wine, big guy. ”

"General, let's give this wasteland a name!"

"yes—"

"This ......" Wan Song is a vulgar martial artist, and naturally he doesn't know how to write.

Wu Yongzi immediately joked: "When I first arrived today, I built five houses in one day, so it's better to call this place No. 5 Liao in the future!" ”

"No. 5 Liao is good!" The name has a memorable meaning.

As a result, the name of the No. 5 Liao began to be recorded in history.

In this way, several houses were built in the area, and some experienced miners began to look for veins around.

The crew of the ship began to search for the veins, and after a day of searching, they did not find them, and at this moment someone entered the valley and saw a golden waterfall on it, which in fact was caused by the high sulfur content of the mine, which caused the yellow-brown iron hydroxide precipitates to settle here.

I wanted to search to no avail, but who expected that in the afterglow of the setting sun, a dazzling brilliance came, and the man ran towards the golden light, and when he got there, he lifted the soil layer, and a golden unearthed object the size of a cold melon appeared in front of him.

"Whaha--gold, I actually found gold."

The man took the object in his hand and ran to the house, and the man who was staying here at the moment saw a man coming across from him with an object in his hand, and when he looked closely, he found that it was not gold.

"I haven't seen this much gold since I'm so big, I bet there must be a gold mine here!"

"It's a dog's head of gold. Thousands of dollars have obtained a piece of gold for the dog's head, which is the mother of gold! "A miner who is familiar with gold mining has taken the gold fast track.

"Doghead gold?"

"Yes, this is a placer gold mine, we just need to look for it in the nearby river beach, and then the gold in the water, we can find a lot of it."

When the man handed this thing to Wu Yongzi, Wu Yongzi's eyes were straight, such a big piece, it seems that what His Royal Highness said is true, and Wan Song was also dumbfounded, such a big gold nugget has never been seen.

Early the next morning, the miners began to look for gold in the surrounding mountains, forests, streams, and streams where the miners found the dog's head gold yesterday, and then did find some impurities in the stones, mixed with gold, and then crushed them, and began to wash the ore in the stream.

After that, at the end of the valley, tracing its source, the miners chose a slope, and then on this basis, began to dig up the earth, digging several feet of earth in the mountains every day, and seeing that the stones below were mixed with gold, digging and chiseling the stones, and using the method of water and gold.

Here the miners are mining gold, and the farmers are starting to grow southern crops such as rice on flat terrain, and northern crops such as beans on mountainous land.

The expedition is well underway, with three ships continuing to follow Zhao's map in search of other minerals, including copper.

――――――――――――――――――

In the second year of Jianlong, on the third day of the first month, Xiang Quanzhou Qingyuan Jiedu envoy stayed in the effect to explain that the opening of the special city port finally had an eyebrow, and Liu Han hurriedly entered the palace to resume his life as soon as he got off the Bianshui wharf.

Liu Han saw Zhao Kuangyin, who was reviewing the folds, and said: "Your Majesty, the minister did not disgrace his mission, and finally brought a letter from the envoy of the Qingyuan Army. The minister sent an envoy to Quanzhou this time, and learned that the Qingyuan Festival envoy attached great importance to maritime trade, and he asked people to open Qu in the city, build a cloud house, attract barbarian merchants on the sea, remove all kinds of harsh taxes and miscellaneous taxes, and allow freedom. Overseas trade includes ivory, rhino horn, hawksbill turtle, pearl, floating incense, camphor and other goods. Under the rule of Quannan, Yi merchants came to China, and the goods in Quanzhou City were abundant, and the commerce was prosperous, known as 'ten thousand cloud houses, and several miles of pheasants'. ”

"It's been a great job." When Zhao Kuangyin heard this, he promoted him to the Shaoqing of Honglu Temple.

Liu Han received the order to thank him, and Zhao Kuangyin issued an order to send other officials to Quanzhou, and sent a decree to let Huang Yuxi temporarily serve as a foreign envoy in Quanzhou City, and bear the taxes of Quanzhou City.

The next day, the attendants of the Yellow Gate who carried the decree went south to deliver the decree.

In Kaifeng City, Zhao Dezhao has been supervising and supervising the ordnance in the past few days, of course, the development of armaments is still under discussion, and it has not been able to achieve Zhao Dezhao's expected goal for a while, and at this time, after the improvement of the blast furnace, two kinds of kilns are produced, such as crucibles and pond kilns, and the feeding material is melted at high temperature.

After Zhao Dezhao's painstaking efforts, the craftsmen who will be the supervisors lived up to expectations, and the improvement of their glaze production and under the guidance of Zhao Dezhao, the glaze began to become transparent, but there were still some impurities, and the texture was not hard and easy to break.

So Zhao Dezhao asked the craftsmen to use the waste, make this part of the glass into beads, and then send it to the market to sell. Such a seemingly transparent glass bead is at least worth the same amount of money, and such a batch of waste can be sold at such a high price, Zhao Dezhao also feels uneasy about his conscience, but he doesn't feel his conscience black when making money from rich people.

However, the work of the glaze has not yet been completed, and it is necessary to continue to purify and improve the hardness of the glazed products, unless some zinc oxide is added in the refining process, and Zhao Dezhao will not be able to find this thing for a while.

Zinc oxide, as a binder, commonly known as zinc white, its characteristics are insoluble in water, soluble in acid and strong alkali, used in plastics, silicate products, synthetic rubber, lubricating oil, paints and coatings, ointments, adhesives, food, batteries, flame retardants and other products in the production.

The boiling point of zinc is 906 °C, when the boiling point is reached, the zinc becomes a vapor state, which is lost with the smoke, and is not easy to be detected by the craftsmen when they smelt, and the memory is a painful thing, Zhao Dezhao remembered for a few days and then remembered the method of refining zinc in "Tiangong Kaiwu": as long as the calamine (i.e. siderite ore) is filled in a clay pot and sealed, piled into a cone, and the gap between the jars is filled with charcoal, and the jars are broken, and the extracted metal zinc ingots can be obtained.

Subsequently, Zhao Dezhao informed the craftsmen who would be the supervisors, and used this method to mobilize a batch of ore containing zinc from the warehouse, and then extract the zinc ingots according to the description of "Tiangong Kaiwu".

After the direct zinc oxide production method is adopted, the waste ash is used to remove impurities by impurity removal equipment to obtain qualified zinc ash, and then the qualified zinc ash is added to the coal [coal] and lime, and the ingredients are batched according to the technical requirements, mixed and crushed, and the crushed material is pressed with a charcoal ball machine, and the pressed zinc-containing carbonite balls are stacked and dried; The dried charcoal balls are smelted with a zinc oxide furnace, and zinc oxide products are collected after reduction, oxidation and cooling.

Then this material was added during the firing process, and after repeated attempts and failures, the fired glass products began to harden, and after the improvement of the craftsmen, the transparent glass finally began to be fired.

On the day the glass was fired, Zhao Dezhao couldn't sleep with excitement.

――――――――――――――――――――

ps. China was the first country in the world to discover and use zinc, and in the 10th~11th century, China was the first country to produce zinc on a large scale. At the end of the Ming Dynasty, Song Yingxing wrote the book "Tiangong Kaiwu", which has the world's earliest record of zinc smelting technology.
