Kong Zhang stayed in Anping for two days, rested a little, and then boarded the "Feiyan" fast traffic ship with Zheng Sen. www.biquge.info The wind was good along the way, and the "Feiyan", accompanied by the "Blue Bird", maintained a speed of nearly fifteen knots, and after two days of sailing, it arrived in Luzon smoothly.

Once ashore, Zheng Sen and Kong Zhang got into the carriage and, escorted by a team of cavalry, went to Zheng Zhihu's headquarters. He will temporarily succeed Zheng Zhihu and will be in charge of all affairs on Luzon. Zheng Zhihu will take the "Feiyan" back to the north.

The carriage drove along the bluestone-paved streets towards Zheng Zhihu's station. Because it was estimated that the siege of Manila would last for a very long time, maybe even a year or two, the Zheng family also built several permanent military camps while enclosing Manila with several earthen walls. Mr. Zheng's base is in a military camp south of Manila.

Escorted by the cavalry, the carriage walked for about two quarters of an hour and approached Zheng Zhilong's station.

This barracks housed an infantry battalion and a cavalry company, an artillery company, as well as direct personnel of the command organs. Because it is a temporary military camp, the conditions are not good, but the safety is quite guaranteed. The barracks were built directly behind the second of the two walls surrounding Manila, and against the back of the wall surrounding Manila, a ring of identical walls made of logs and rammed earth, with several tall watchtowers built on top.

There were two moats on the outside of the wall. There were drawbridges on them, and when the convoy reached the front of the drawbridge, a cavalry officer rode up on horseback and said a few words, and then the drawbridge was lowered, and the convoy rumbled across the two drawbridges and entered the barracks. Then he stopped in front of an empty field.

As soon as Zheng Sen got out of the car, he saw Zheng Zhihu with a few people coming up. Zheng Sen hurriedly saluted and said, "How dare Second Uncle Lao greet him?" ”

Zheng Zhihu hurriedly supported Zheng Sen and said with a smile: "Ah Sen, I shouldn't have let you come over so early, but things here are too messy, and your second uncle and I are really too big...... Now, those Spaniards are determined to be turtles with shrunken heads, and they will not come out. Those natives, like a swarm of rats, come out from time to time to make trouble. If you want to hit them, they will burrow into the woods, like a rat in a rat hole...... If you want to say that it was still Damu, you dealt with these people in Taiwan back then, and you have some experience. So, I had to call you. By the way, your mother-in-law didn't complain about the second uncle, right? ”

"What did the second uncle say? How could she have such an idea about her own affairs. Zheng Sen also smiled, "Second Uncle should tell me about some of the situation here." ”

"It's fine." Zheng Zhihu glanced at Zheng Sen and said, "Look at you like this, you haven't been tired after two days on the boat, but you have a bit of the taste of your second uncle and me." Your second uncle and I just don't care how long we sit on the boat, as long as we take the boat, we won't be tired, and we will feel comfortable. Well, since you're not tired, I'll take you for a walk. ”

Speaking of this, Zheng Zhihu turned his head and glanced at Kong Zhang, who came down from the carriage with him, and saw that his face seemed to be a little not good, so he said: "Mr. Kong, you can't compare to us who are floating on the sea when we are young, this journey is really hard." Now that there is still a while before eating, why don't you go to the room and rest first. ”

The comfort of the "Feiyan" has never been very good, this trip was in a good direction, and it ran fast, but at the cost of swaying even more. Originally, Kong Zhang was not unable to take a boat, but this time, he still vomited many times along the way. Kong Zhang was also very familiar with Zheng Zhihu at this time, and in front of him, he didn't want to deliberately support it, so he nodded and said, "Thank you, Second General." I do need to take a break. ”

Zheng Zhihu led them through several barracks built of logs, and when they reached the back, there was a courtyard with a two-story blue brick building. Zheng Zhihu said: "This house has just been built recently, and it is not as good as the house, but it is still much stronger than the log house." The other barracks are gradually being converted into brick houses, and several have already been renovated over there, and in about a month or two, everyone will be able to live in brick houses. ”

Zheng Zhihu said as he walked in with them, and the soldiers and officers he met along the way all raised their hands and saluted them, and Zheng Zhihu also returned the salute one by one, it can be seen that he has adapted very well to these rules in the model army.

Zheng Zhihu called a soldier and said to him, "Baoguo, you take Mr. Kong to the back house to rest." Then he turned his head and said, "Asen, I'll take you to see the map first." ”

The two said goodbye to Kong Zhang, and then went into the map room together, where there were many maps of the area around Manila that the Zheng family had recently drawn.

Due to the lack of surveying and mapping technology, the maps of this era are completely incomparable with the maps of later generations in terms of accuracy. Even though Zheng Sen tried very hard to introduce some modern map drawing techniques into the drawing of maps, and even wanted to make a more intuitive sand table for a while, the technical limitations of reality quickly gave him a blow to the head. Accurate maps rely on accurate mapping, and accurate mapping relies on a series of high-precision mapping tools. Although Zheng Sen's skilled craftsmen have worked hard under his guidance to make such an artifact as vernier calipers, because of material problems, Zheng Sen's vernier calipers are heated. The effects of expansion and contraction are so obvious that when it comes to making high-precision measurements, Zheng Sen's vernier calipers need to be soaked in a mixture of ice water to ensure that the temperature is zero degrees Celsius. In other words, every time you use this thing, you have to consume a lot of saltpeter. But even so, the baseline accuracy is still only one-tenth of a millimeter, which is still far from the accuracy of two percent of the millimeters in later generations. However, this is already a very high accuracy for this era, but for the tools used to make mapping, such accuracy is not enough, because in long-distance mapping, small errors in the initial stage will be magnified. And even today's precision is completely handmade, and the speed and cost of manufacturing are also highly problematic. So, not to mention making a sand table, even a map, it's just slightly better than the average level, and it can't be compared with those maps of later generations.

However, at this time, Zheng Zhihu only used the map to explain the situation to Zheng Sen, and the requirements for the accuracy of the map itself were limited.

"Asen, you see, this is Manila City, and now we have two walls to surround it. Of course, there is also a sea side, and our fleet has blocked the sea routes, but at night they still have the opportunity to transport a few people out or in small boats. Of course, if there are too many people, it will definitely not work. And then with Manila as the center, you see, along the wall, we have three more barracks. Then there is the Chinese Ghetto and the Xingang District. This area is relatively fine, basically nothing will happen, and it is relatively safe. Even if you go out empty-handed, nothing will happen. Zheng Zhihu pointed to the map and introduced to Zheng Sen, "And here, here, and here, these Zhuangzi, the vicinity of Zhuangzi is quite safe, but on the way to and fro, you already need to carry a gun to travel." But these places can at least be able to farm safely, and it's not the worst. The worst part is ...... in this piece."

Zheng Zhihu pointed over there again, and then found that that it was already outside the map. A young officer hurriedly pulled out some new maps and unfolded them on the large table.

"Asen, this map, you just need to look at the general meaning, these places are not very peaceful, and they are newly occupied, this map is not drawn seriously." Zheng Zhihu explained first.

"Second uncle, I understand." Zheng Sen said.

"You see, here, Zhaozhuang, Gaojiazhuang, and this Majiahe by the river, these villages are all newly robbed by Boss Zhao, Boss Gao and Boss Ma with the militia after we beat the Spaniards into Manila recently, and they were originally indigenous Zhuangzi. Well, hehe, even in Zhuangzi, you have to take a knife and put it next to you when you sleep at night. Otherwise, some natives would quietly take advantage of the night to crawl in from the wall to kill people and set fires. Also, just two days ago, there was an incident in Zhao Zhuang. Early that morning, the men on duty saw that someone was moving the seedlings in their fields, so they hurriedly organized a group of people to go out with muskets to expel the people, and who knew that the natives had put hundreds of cobras in the field...... These people rushed over recklessly, and as a result, seven or eight people were bitten to death at one time...... Another time, in Majiahe, in broad daylight, someone touched the edge of the fence and threw fifteen or sixteen hornet's nests into it, and as a result, almost everyone in the Zhuangzi was injured, and three others were stung to death. Now Boss Zhao, they are almost unable to invite anyone who dares to go to their new village. I want to lose Zhuangzi and return it, but I am unwilling to continue to guard it, and I can't plant the field well, and I always have to spend money there...... In short, these places are very dangerous. ”

Zheng Sen nodded, thought for a while, and said: "In this way, according to the different security status, well, that is, the different security status, we can divide the territory we control now into the following three categories: like the area near the military camp, and the area near the port, which is very safe, and usually a person can go out empty-handed, we call it the 'security area'; A place like Majiahe where security is completely unguaranteed can be called a 'non-security area'. We need to expand the number of security zones and reduce the number of non-law zones. Well, it's called 'Operation Law and Order Enhancement'. ”
