Early the next morning, the Thunder Sword team set off with a few Ming guides to explore the surrounding mineral deposits. And Pan Mingzhong's side started the transaction early: several delegations from indigenous societies started to set off in the middle of the night.

The villages and communities under the Kaida Gran tribe, who have trade needs, will come here today and tomorrow to trade. Therefore, Pan Mingzhong did not dare to be careless, and after allocating the guard and trade personnel, he began to patrol the field with an AK.

By noon, more and more natives came to trade, and when Pan Mingzhong saw the big customers with bamboo baskets coming one after another, he ordered his subordinates to take out their own fist product: glass balls.

The glass balls that crossed the crowd weren't the kind of junk that the Dutch used to buy Manhattan.

The glass ball that crosses the public: the shape is round, the surface is smooth, the interior is clear, the light transmittance is high, the size is like a walnut, it is carefully polished and polished by the glass factory in the kiln area with scraps, and some of them are also used to drill holes and wear ropes with high-speed drilling machines, which is a rare high value-added glass ball treasure.

The natives are really knowledgeable.

The natives, who had already finished changing the sulfur in the basket and were about to go home, flocked to the glass ball booth one after another. When a fat earth chief was dazzled by the sunlight refracted by a large necklace of glass balls, he hung the glass balls around his neck like a sand monk, and then poured out a thing from the bamboo tube behind his back and handed it to Pan Mingzhong.

A piece of dog's head gold the size of a cigarette box.

Pan Mingzhong is a kind-hearted person, and after quickly putting the dog's head gold into his trouser pocket, he grabbed a few glass balls from the big glass bowl in front of him with an expressionless face and supplied them to the chief: We can't let the comrades in the countryside suffer! The crossing force is high, and it is not to take advantage of this.

The base exchange rate was set at this moment.

Later that day, someone who had been secretly laughing in the cockpit for 10 minutes was playing with the dog's head gold and golden sand in front of him, and at the same time used the radio to report the achievements of the thunder sword 10 miles away.

"The place where you stay is called Jinshan District, and the Qing Dynasty is called Jinbaoli, why is it called that? Isn't it because there is sand gold in Sulphur Creek? Lei Jian tried his best to show that his brother didn't care in an understatement tone, and at the same time stepped up to order the team members to dig sand - he also wanted to go back and see the real dog's head gold, people who study geology are obsessed with this thing!

Originally, Liao Tianding thought that the people on the ship would take out high-quality iron pots to exchange for gold, but who knew that people would use glass balls to get it......

Therefore, Comrade Liao Tianding, the local comprador, was also smacking his tongue at this moment. You must know that the natives here have been tempered by foreign trade for thousands of years, and they know very well what goods are worth, and it is usually difficult for outsiders to exchange them for yellow and bright sand gold.

But the traversal did.

Not only did they do it, but after that, the people on board also took out a few beautiful "big paintings" for everyone to see. At the same time, they also asked Liao Tianding to tell the natives that the things on the paintings could be traded in the future.

A few large photographs show pyrite, alum and volcanic ash.

Pyrite and alum stone have clear records of production in the Datunshan volcanic group. In addition, volcanic ash is a high-grade cement fine aggregate. The volcanic ash that has undergone natural magma calcination and eruption grinding can be added to cement up to 40% to become Portland pozzolana cement.

This kind of cement is naturally suitable for concrete engineering in water and humid environments, and is the most needed building material for a certain force currently entrenched in the coastal temperate and humid zone.

......

At the end of the afternoon, guests from afar gave the host an impromptu performance.

The sailor, who was 200 meters away, fired the rifle in his hand. Accompanied by white smoke, fire, and gunfire, were broken bamboos, wooden blocks, and broken stones on the stone platform in the middle of the fair.

The natives sitting in the bamboo hut on the side, this time they didn't need to pay the price of blood, and they saw the power of the hot weapon.

After the performance, looking at the villagers who were leaving while discussing fiercely, Pan Mingzhong stood at the bow of the boat and sighed: I hope these people can meet each other in the future. You must know that once the war starts, it will not be a simple suppression. In order to pass through the urine sex of the public, it is necessary to uproot it, and the next step is forced migration, and the Madou Society in Tainan is a ready-made example.

......

The Yuandou stayed in the bay at the mouth of the sulphur stream for three days. Due to the fact that some of the "high value-added" goods were relatively large, which exceeded the expectations of the nearby natives, when the Yuandou returned to the sea, there were still a lot of goods left with the representatives of Mingren Village.

These goods would be exchanged for sulphur from the natives and then transported back to Dacheng by the next batch of ships.

Thunder Sword's side also completed the task. The high-grade iron sand producing areas near Sulphur Creek have now been marked on the map by him; In addition, just like Xiuguluan Creek, the terrain near Sulphur Creek was also photographed by him, and after turning it over to the big office, someone would naturally study how to open a base.

Three days later, before returning, the Yuan Dou also went to the Spaniard's castle and made a simple announcement of the situation in Mingren Village, and the subtext was: You have nothing to do in the future.

...... Rounding the Cape of Fugui in the upper left corner of Taiwan, the Yuandou began its journey southward homecoming.

When they arrived at the mouth of the Tamsui River, a certain ship deliberately lowered its speed and used its binoculars to observe the castle that the Spaniards were building.

Since it was a tailwind to the south, the Yuandou was very fast, and it ran to the mouth of Houlongxi the next day.

Houlong River, which originates in the Kali Mountains of Miaoli, is the largest river in Miaoli, with an average width of more than 60 meters. At the present day in the 17th century, Houlong Creek was the only way to enter the Miaosu Mountains. The purpose of choosing Taiwan to take root was for the Miaosu Oilfield on the bank of Houlong River.

And the Yuandou, who was in a hurry to return home, only turned around and left after a brief exploration of the mouth of Houlongxi this time - oil exploration is different from iron sand exploration, and Yuandou needs to rest and recuperate.

As the expedition team was about to return home, the dried timber stored in the hold was useless. On the final voyage, the Yuandou's gas generator began to operate at full capacity, sending the sand boat back to the crew as fast as possible.

......

Entering the Dayuan Channel after a half-moon absence, and seeing that the Haidilao that passed by was still slowly digging a sandbar there, Pan Mingzhong and Lei Jian were still a little excited at the moment.

Naturally, the princes of the big office who heard that the exploration ship was going home did not dare to slack off, and held a meeting on the same day to quickly arrange the results brought by the exploration team.

Once the information is available, the preparatory team, which has been formed jointly by the mining and military sides, will now begin its work. The planned occupation of the Spanish castle in Taipei and the development and remediation of the Sulphur River basin should be formed into a plan for use in the development process. As for the iron sand on the Xiuguluan River, we have to wait for the time being: Taipei, which has access to both sulfur and iron, has a significantly higher priority for development.

Of course, these tasks will not be implemented until August at the earliest.

First of all, the upcoming summer, the period from June to August, is the time when Tainan has the highest rainfall/typhoon concentration of the year. Therefore, all the industrial and mining areas, factories, and residential areas under the jurisdiction of the forces have recently been carrying out flood control, drainage, reinforcement, and bundling of these disaster preparedness work, and the entire force is in a state of contraction, and there are no spare resources to go to Taipei to do things.

Secondly, it is already mid-June, and according to the information sent back by Fuzhou, Zheng Zhilong is already on his way to meet Xiong Wencan. It is foreseeable that there will be a series of land and sea battles waiting to cross the army, so this is the number one event that has attracted most of the attention of the crossing crowd at the moment, and the rest will have to be sidelined.

At the end of the meeting, after Xia Xianze hastily praised Pan Mingzhong, the topic quickly changed: "When will you go to Miaosu?" ”

Pan Mingzhong glanced at the bosses of various departments in the venue who were blinking and staring at him with big eyes, and couldn't help swallowing and foaming: "7 days, rest for 7 days and set off!" ”

"The people of Africa are still grazing, you are gasping, 5 days!"

"Well, 5 days ......"

The sad Pan Mingzhong and Lei Jian had to compress their rest time. Originally, I was going to linger with my sister for two more days, alas, not to mention the capitalists, and the traverser was not merciless when he squeezed his hands.

......

The sun is dazzling, the sky is blue, the sparse clouds are floating overhead, and the refreshing sea breeze is just a pleasant day on Dayuan Island.

Dayuan Island is close to the northwest corner of the beach on the side of the strait, and it is noisy.

This piece of sand is commemorative: it was here that the traversers on the Dog's Eye rushed down the beach, bravely charged forward, and led the sailors to seize the Dutchman's merchant house and begin the great journey.

Today, the beach has been turned into a training ground.

Originally, the training ground was near the merchant hall, but later a big man was noisy, so he drove the recruits here. Although it is a little off, the facilities of the training ground are still very complete, and some obstacles and equipment used for military training in later generations are found on the beach.

Today's training ground was a 400-meter obstacle crossing assessment, and the soldiers of the first battalion and the first company of the army participated in the assessment.

As the first batch of soldiers recruited by the crossing forces, these people in the first company can be regarded as the royal family with red roots - although the crossing people have not yet pulled up the imperial flag, but this is already a technical problem and will be solved soon.

The 100 soldiers who are sweating on the playground have another identity: cadets.

Fortunately, they were trained as cadets, and as the ranks grew, they became natural junior officers. Moreover, the conditions for their graduation are very relaxed: they only need to learn elementary school language and be proficient in calculating battlefield data, and they can successfully graduate and get their military officer certificates.

After the whistle of "Di......", another row of soldiers began to stride on the runway, which was composed of eight groups of obstacles, including cross-piles, trenches, low walls, high-board jumps, ladders, single-plank bridges, high walls, and low-pile nets.
