Not long after Zhu and Gu cooperated to build a porcelain workshop, a craftsman who used to make pottery in the pottery workshop and now moved to Taiwan, because his share of land is at the foot of the extinct volcanoes in Datun. Clay was accidentally discovered while reclaiming wasteland, and the large reserves made the craftsmen who had been cooking pottery for most of their lives overjoyed. Relying on the craftsmanship of the family, he pulled his children and grandchildren to make a family-type pottery workshop, and sold the pottery bowls and pots produced to nearby residents, and embarked on the road of well-off.

Subsequently, exploration teams organized by some powerful and wealthy businessmen made more astonishing discoveries when they explored the Taipei Basin and nearby mountains.

Mercury has been found at the foot of Keelung Mountain, and several alum deposits have been released.

Clay was also found on the west bank of Tamsui ten miles north of Taipei County, but after being inspected by craftsmen in the Governor's Mansion of Taipei County, it was found to be refractory clay, which was the refractory material used by King Yan to build a steelmaking blast furnace in the cast iron city of Liaodong.

Low-grade iron ore (limonite magnetite) has also been found in the Taipei Basin, iron ore sand has also been deposited in the Tamsui estuary, gold sand in the Keelung River, and the later Badouzi Coal Mine has been found not far from the coast in the east of Keelung Port.

In the place where Zhu Dan found porcelain clay also found rich sulfur ore, in the Datun extinct volcanic group is very distributed, as soon as the news came out, it was valued by Xue Maoxun, the governor of the Governor's Mansion, and wrote to Li Yu.

It must be known that sulfur is the main raw material for making gunpowder, and Li Yu does not have a sulfur production area in his hands, and the discovery of sulfur ore in the extinct volcano of Datun undoubtedly makes up for a major shortcoming in Li Yu's development of gunpowder weapons.

The extinct volcanic group of Datun has successively discovered porcelain clay, clay and sulfur, which attracted many prospectors for a time. After careful investigation, it was surprising to find that clay was the most abundant, followed by sulfur.

When the businessmen from Liangjing in Taipei County learned the news, they were all overjoyed. They knew that King Yan had monopolized the cement market in Liangjing by using the cement production in his hands, and the cement transformation of the streets of Liangjing alone made a lot of money, which made them businessmen very angry.

Spending a lot of money to explore the methods of cement production finally let them know the secrets of cement production. Originally, cement was just made of limestone, clay and a small amount of iron ore powder ground in proportion to mix into raw meal, and then calcined to obtain clinker. The clinker and gypsum are ground together and mixed in proportion to obtain cement, which is the most common Portland cement.

Limestone, which accounts for 80%-90% of cement, is ubiquitous in Taipei. Coupled with the discovery of low-grade iron ore and the accumulation of iron ore in the freshwater estuary, the Taipei Basin is simply a natural place to produce cement.

What's more, the clay of the extinct volcano of Datun has the same properties as volcanic ash, and the special porosyl Portland cement with better performance than ordinary Portland cement will be obtained when used to make cement. In terms of performance, the cement produced by Li Yuxuanji Commercial Bank's cement mill was directly thrown off a few streets.

Li Yu was a non-science student before he crossed over, and he didn't know that there was special cement, and he didn't know that he could get special cement by adding volcanic ash.

Unbeknownst to the businessmen of the two capitals in Taipei County, they happily organized people to build cement mills under the extinct volcanoes in Datun, and by mistake produced cement with several grades of performance better than that produced by Li Yu, the inventor of cement.

There was no patent in the Tang Dynasty, and the merchants who opened the cement mill would not pay Li Yu royalties.

The cement market in the Liangjing area was completely monopolized by Li Yu's Xuanji Commercial Bank, which was not owned by Li Yu alone, and its shareholders involved many powerful people in the DPRK and China. The merchants of the two capitals did not have the courage to pick up the tiger's whiskers and go to the bowls of the powerful to grab food. Taiwan is different, Xuanji Commercial Bank's cement has not even carried out business in the south, let alone the newly developed island of Taiwan.

Don't you see the county seat of Taipei, whether it is the city wall, the street or the official office, it is all rammed earth? There was not a shadow of cement in sight.

There is a lot of cement produced in Taiwan, and it can't be used locally, so it can be shipped back to Jiangnan, Huainan, and Lingnan for sale. Cement is such a good building material as it is not worrying about the road at all, not to mention that there is no competitor in the south.

The minds of the merchants are very good!

By mistake, the businessmen took advantage of the rich clay deposits contained in the extinct volcanoes of Datun to develop Taipei into the largest and highest-quality cement production base in Datang.

Nanyang is a tropical rainforest with high temperature and rain, and the trees decay very quickly, and it will not take long for the city to be built with rammed earth and timber before it collapses under a heavy rain, and it is necessary to build the city with cement.

As a result, Li Yu has been developing Nanyang and implementing the plan of building a city to control the surface of the city, and has long relied on high-quality cement produced in Taipei.

……

With the discovery of limestone, china clay, clay, refractory clay, alum, sulfur, iron ore, and mercury in the Taipei Basin. The scope is then expanded from the Taipei Basin to the whole of Taipei, and the gold sand in the Keelung River originates in the Keelung Mountains, and the rich gold deposits in the mountains on both sides. Tens of thousands of years of guano fossils are stored on Cotton Island outside Keelung Port, and there are abundant coal mines from the east coast of Keelung Port to Keelung Mountain.

It includes gold and copper deposits in the Jinguashi Place, the largest gold mine in East Asia, oil from Miaoli and graphite in the Yilan region that has not yet been conquered.

The abundance of minerals, coal, clay, gold, sulfur, limestone is famous for its enrichment and good quality, so that Taipei deserves to be called a cornucopia, and the Taipei Basin is a small cornucopia.

Of course, Li Yu, who was the initiator of the development of Taiwan Island, still knew nothing about the treasure he had picked up. The only thing I remember is the richest gold mine in East Asia located in the upper reaches of the Keelung River.

The discovery of various minerals in the Taipei Basin has led to the emergence of corresponding workshops. Lacking workshop labor, the powerful and wealthy merchants who set up workshops chose to spend money to rent slave laborers in the Governor's Mansion, and the Governor's Mansion was also happy to rent out to them the tens of thousands of slaves captured by the previous conquest of the Fan Society to make a sum of money.

The establishment of a workshop requires craftsmen with corresponding skills, and Taiwan cannot solve the needs locally, so the powerful and wealthy businessmen can only recruit a group of craftsmen from the mainland, bringing a small wave of immigrants to Taiwan, and they are all skilled talents.

Coupled with hundreds of square kilometers of fertile land in the Taipei Basin, the grain and sugarcane produced when it is all reclaimed; The navigable freshwater river that runs through the basin brings easy navigation.

It has laid a solid foundation for the development of Taipei into a commercial city with developed handicraft industry in the future.

……

When the tide was sparked by the discovery of business opportunities in the Taipei Basin, the 10,000-strong army assembled in the north of Taipei City in ten days waited solemnly.

As the governor of Taiwan, Xue Maoxun rode a tall horse to inspect the whole army, and his eyes swept around the various armies, so that the hearts of the generals of all departments were raised to their throats, for fear that the soldiers and horses under his command would dissatisfy the governor, so they were punished for this.

Among the 10,000 soldiers and horses collected this time, 800 soldiers of the Chaos Guard were transferred, and 5,020 unity soldiers were recruited, including 300 cavalry. Each subordinate society conscripted 4,000 soldiers, led by the head of each society or the eldest son of the head of the society.

After Xue Maoxun checked that it was correct, he stood on the platform of the generals, waved his hand and escorted a Magalan leader who was captured last time to the front of the whole army to kill the sacrificial flag, and shouted: "Go!" ”
