Green Butterfly squinted her eyes and smiled quietly as she watched the children playing in front of her. The other three wives and concubines didn't know what they were saying, and laughed like a bunch of laughter. The eldest sister Bi Niang didn't come, but the third sister Run Niang and the twins were also there. The pair of villains were very likable. Even Li Shu was a little jealous sometimes, why didn't she give birth to a daughter?

During this period, the third sister Runniang went here all day because of picking up Helan Minzhi and Helan Ping'er. Sometimes she just sat in the classroom and became a student. However, this little girl is indeed smart and deserves to be the sister of the palace maid.

The third sister Runniang pulled the hand of Green Butterfly and didn't know what she was saying. Green Butterfly pursed her lips and slapped the third sister Runniang gently, with anger on her face. He hesitated for a while, and then picked up a wine cup from the side and handed it to the third sister Runniang. The girl's proud expression seemed to be a general who had won a battle, and she slapped it in small mouth. Green Butterfly was whispering something in a very cute expression. When I first saw Green Butterfly, the beautiful little girl had grown up now. Her original green body seemed to be like a day, and she was almost as tall as Cheng Luanluan, the tallest among my wife. That time, if I hadn't discovered something wrong earlier, I'm afraid that now, this dear Green Butterfly had already...

Thinking of this, I couldn't help but shudder. Well, at least the appearance of the coal stove saved countless lives. Even if I had a polluted atmosphere, even if the environmental protection organizations in later generations used my head to draw a red cross as a sign of pollution behavior, I would never regret it.

Li Zhi nodded in agreement: "This is, in the past winter, when the palace was burning carbon, my head hurts. Now it's much better. Moreover, this reduces the damage to the forest and keeps the water in Guanzhong area." The subsequent words were very heart-wrenching. It seems that the prince is quite concerned about my teachings. I have made progress. I happily greeted the prince again.

However, Li Zhi asked me in a greedy manner, "Have you found other mineral deposits?" Li Zhi's eyes glowed yellow, and after I used visual measurement and positioning. After using psychological spectrometer analysis, the conclusion was that the prince was crazy about copper and his eyes were full of brass color.

I could only shake my head helplessly: "I didn't find this. Even if I had it, it would definitely not be as good as Luzon. Oh. It's a pity to say that I came here. I don't lack anything in the Tang Dynasty, but the copper and iron are really powerful. I need copper to cast coins and copper to build utensils. My Wushu Institute of the Tang Dynasty is almost crazy about copper. But I just have a little pitiful land output every year. If it were this time, Luzon would be in the hands of my Tang Dynasty."

———————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————

Su Dingfang also sighed: "Yes, if there is enough copper, I don't know how many times the artillery of my Tang Dynasty can be increased. It's okay to attack cities and villages or defend the city with all my heart. This thing works very hard. If the Tang Dynasty had such a powerful weapon back then, I would probably have been able to pacify the Central Plains in the early years." Su Dingfang's words were suspected of flattering, but I still happily accepted this praise. After all, the emergence of firearms represents not only the birth of a new era. It also represents the great invention and creation of the advantage of force from nomadic peoples to farming peoples.

"Bronze..." Li Zhi gritted his teeth and said with hatred, as if that thing was a feud with him. "For the people's livelihood of the Tang Dynasty for thousands of years, I will find a way to ask my father to send troops to occupy Luzon as soon as possible. I, the Tang Dynasty, can't always worry about copper." Li Zhi patted the table with his ground force, and could see that Li Zhi's expression was no different from the gambler who lost in a hurry. But it was also true that in this era, copper could be called an all-round metal, and even steel was not as important as copper, because copper could not only make daily necessities, but also the raw material for currency in the Tang Dynasty.

It is not easy to cast copper coins. It was a major event that caused the government's headache from the former Han Dynasty to the Zhenguan period. The output of copper land was not small compared to the Tang Dynasty, but because of the wide range of uses of copper, it caused the shortage of this base metal. Moreover, the cost of the mint industry was also extremely high. Under normal circumstances, only small profits could be made. Jia Yi of the Han Dynasty pointed out that "the feelings of minting money are not confused and tricky, and it is impossible to win." The same was true in the early Zhenguan period. The cost of minting money for the government was about 700 coins per thousand coins, which is a hundred. The cost rate of 70 parts is not included in the craftsman's land servitude money. Moreover, in addition to Chang'an, Luoyang and Jinyang, the Jianghuai land also had coins in the Jianghuai land. However, if the Jianghuai money was transported from the Jianghuai land to Chang'an and the freight was connected, the total cost of each guan was 3,000 coins, that is, three guans, which means that minting money is not profitable, but loss, and it is a big loss. Therefore, someone once wrote a letter to Uncle Li, the Emperor of the Tang Dynasty, if the money is not mixed with lead and iron, there will be no profit, and if it is mixed with money, it will be bad, which is the so-called inferior money.

The government was in an embarrassing situation in this dilemma. Generally speaking, in the early days of the dynasty, the economy was running well and the national treasury was abundant. At this time, the money was often of good quality and heavy as the document, and the control of bad money was stricter. However, when the middle and late period was full of crises and the finances were short, bad money was often issued as a means to alleviate the crisis.

However, this situation has improved since the previous year and has begun to change. Now, the Tang Dynasty coins are no longer the casting method, but the hydraulic press used by the Wuyan Institute to stamp armor. Using this method not only greatly reduces the cost, but also speeds up the speed of minting. What is even more gratifying is that the cost has dropped from the initial 700 coins to 300 coins. After all, it costs money to collect copper, and tin and lead to dissolve copper and lead into copper plates.

But the problem is that there is only so much copper, and no matter how fast it is to cast coins, it is useless. Not to mention Li Zhi, Uncle Li is also worried, and the Ministry of Revenue is also worried. The copper coins of the Tang Dynasty are in a tense state every year, not only because of the Tang Dynasty, but also because of the surrounding countries. They have already regarded the copper coins of the Tang Dynasty as hard currency, which is equivalent to the Tang Dynasty's minting industry that needs to support the economic development of dozens of countries. This is of course a good thing, but the problem also caused the currency tension of the Tang Dynasty. Fortunately, in addition to copper coins, silk cloth can also be used as physical currency. Otherwise, the Tang Dynasty would really fall into an embarrassing situation where there is no money available. This has also formed a strange phenomenon. The Tang Dynasty is rich in oil, but the oil and water are too thick. If there is no fresh water mixed in, everyone stares blankly at the lumps of oil.

"Xiaozhi, your idea is good, but you should not disturb your father for the time being. If you want to occupy Luzon Island, it is not something you can do just by saying it. It also involves all aspects of things. Moreover, the port of Liuqiu Island is also in the early stage of preparation for construction. Therefore, we must be patient. At least within this year, I think it is unlikely to develop Luzon Island." I also feel a little regretful, but I cannot make the aggression and thoughts of Li Zhi.

———————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————

"Why?" Li Zhi didn't understand at once, but Su Dingfang narrowed his eyes and looked thoughtful. Don't look at Su Dingfang as a military general. This guy has more eyes than anyone else. His eyes are unique when he sees things and judges things. Seeing me smiling at him, Su Dingfang smiled and said, "Your Highness, actually, Brother Jun means that when we can handle things in the north first, then your Majesty can breathe a sigh of relief. There are people in doing things. There must be a lot of people in mining, right?"

Li Zhi slapped his head: "Haha, I'm negligent, right. With people, our Tang Dynasty can do these things, right?" The three of us used a look of temptation that could only be understood. After all, only the top leaders of the Tang Dynasty knew about this matter. Ordinary people should not talk nonsense, otherwise it would definitely cause storms. Although there was no big impact on the overall situation, corrupt scholars always muttered in their ears, no one could stand it. Although the slaves still existed in the Tang Dynasty, they just quietly entered the village and shot them.

Li Zhi skillfully opened the topic: "Brother Jun, you are so powerful this time. Tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk

"Come on, what's the number one person in the Tang Dynasty? I'm just following the old man's butt and waiting for the dirt." I still have a clear understanding of this. Whether we command infantry and cavalry or navy, we are all lay people at the level of laymen. But we are lucky and are the leader. Besides, our troops have been guided by famous generals for thousands of years, otherwise we will definitely throw our face to grandma's house.

"Oh, it's rare. This is the first time I've seen Brother Jun say humble words." On the side, Li Yexu came up with a drink. I glanced at him: "When did you say that, when will I be humble? But generally speaking, I plan and then act and don't fight a battle that I can't be sure of. However, I'm really a big girl's marriage. If I'm not humble, how can I get benefits from General Zhang?"

"Hahaha, I said, it turns out that Brother Jun, you have such an idea. You are so smart. Well, it seems that Lao Su must learn two tricks from you to achieve it." Su Dingfang also pretended to be on the side.
