The next 3 days. The various materials, equipment, and carriages needed to make salt became more orderly after Pei Yun arrived at the post, and Pei Yun even knew how to make some tools, such as special shovels and gauze for filtration equipment. At Yang Er's suggestion, Pei Yun was able to arrange it in an orderly manner. Yang Er was very satisfied with this, and waited for the news of them to protect them.

Finally, on the afternoon of the fifth day, the entourage of the soldiers who came to protect the children came outside the big tent and brought a message. The entourage of the soldiers reported the situation of Gulu Village and Jiehu Pond to Yang Er and others in detail. plus where Pei Shiju got the information from Luzhou Mansion Yin. Yang Er has a general understanding of the current Gulu Village and Xie Lake.

Yang Er said to Pei Shiju, Pei Yun, Li Jing and Zhai Rang: "It seems that Gulu Village can be built into a military camp on its basis, which can accommodate at least 2,000 people. Water is a problem that needs to be solved by ideas, and everyone will discuss it. In addition, Gulu Village is not far from the lake, and I originally wanted to dig and build a salt pond outside the village based on Gulu Village, but there are no stones around, so it is not easy to solve. Is there any other way for Pei Gong? After Yang Er finished speaking, he looked at the four people, and finally his eyes fell on Pei Shiju. He was a native and he should know where the stone was produced.

"Lord Wang, it's not difficult to get water. It can be solved by digging a few deep wells in the village. But it's quite difficult to build a drying pond with stones. The east of this river is full of sand mountains and earth mountains, to take the stone must go east to Taihang, Wangwu two mountains or west to Huashan, both places are far from suitable for travel. Pei Shiju lowered his head and replied slowly.

Yang Er agreed with this and nodded, even if he guessed the stone, it would be a problem to transport it if it was too far.

"Lord Wang, do you have to build a pond to dry salt? Can other containers be used to hold water and dry salt, such as buying and making large quantities of iron pots, or other water containers? Pei Yun said at this time.

"It makes sense, you can buy a thousand large iron pots, with a wooden frame as a seat. There is no need to dig salt ponds. Money is not a problem, it can be provided by my Jin Wangfu, but this large iron pot needs to be specially cast, can Master Pei have a way? ”

"There are many blacksmiths in Luzhou, and you can solicit blacksmiths to customize, and we can buy them. It's just that there is definitely not so much rough iron in the blacksmith shops, and this needs to be done by Yin of Luzhou Mansion to use the inventory of iron and stone. ”

"Then Lao Pei calculated the amount of iron needed for a thousand cauldrons of more than 5 feet. This king personally went to Caifu Yin to take a trip, and there was not enough iron in his treasury, so I wrote a letter to Jinyang Mansion to find Tang Guogong. The matter of using iron must be resolved within 20 days. ”

Everyone nodded yes.

"General Daoxing, you will lead 1,000 soldiers to Gulu Village early tomorrow morning, and merge with Lai and Liang Er to build a shack on top of the original village for the use of soldiers and all the people. Remember that men and women are separated from each other. ”

"Order." Li Jing got up and replied.

"General Zhai, you take 500 pro-soldiers and 600 people to escort grain and grass to follow General Li to Gulu Village, and protect the safety of Pei Gong on the road, there must be no loss."

"Order." Zhai Rang got up and replied.

"Pei Gong, after you arrive at Gulu Village with the brigade, you will arrange for the craftsmen to survey and drill wells, and wait for me to come back." Yang Er turned his head and whispered to Pei Shiju. Pei Shiju is older, nearly 40. Yang Er didn't want him to go back and forth to Luzhou with him, and he might have to go north to Jinyang for a long time, for fear that this old Pei Tou's body would not be able to bear it.

"Your Highness, don't worry, I will survey the water source as soon as I arrive, and when His Highness comes back, I may be able to drink water, hehehe!" Pei Shiju twisted his beard and said with a smile.

"Master Pei will go to Luzhou with me tomorrow, bring a few clerical relatives with gold and silver, maybe there will be a big purchase to ensure the smooth production of salt." Yang Er said to Pei Yun next to him,

Pei Yun nodded yes. "I'll make a list of what I need tonight, and when I get to Luzhou, I can buy them separately, so that I won't make a mistake."

At dawn the next day, after breakfast, the teams set out as a team. Li Jing led two flag officers in front, 1,000 infantry divided into 500 teams, led by the main and deputy flag officers, set off neatly, and went east to Gulu Village under the guidance of the soldiers who came to protect the children who reported yesterday, a straight-line distance of about 120 miles. It takes two days to arrive. Because behind the infantry, Zhai Rang's people, grain and grass marched more slowly.

Yang Er took Pei Yun and others and 200 personal generals before dawn and rushed to Luzhou on horseback. It is estimated that it will arrive after noon.

The flowers are divided into two flowers, one on each branch. Li Jing and Zhai Rang and their entourage will not talk about it for the time being. Let's just say that Yang Erluzhou and his party.

At noon, Yang Er and his entourage arrived in Luzhou. Hearing Menzi's report that the King of Jin came to the mansion in person, Cai Fuyin was really scared, and hurriedly greeted him to the back hall study to serve tea.

Yang Er's face was dusty at this time, although the air in ancient times was good, but the sun was too scorching. Yang Er's face was even more ruddy, and he also looked a little mature that did not match his age. Cai Fuyin hurriedly asked the two maids to fan behind Yang Er.

"Your Highness has never been far away to greet the official of our mansion, and I hope Your Highness will not blame you!" Cai Fuyin greeted him with a smile.

"It's okay, this king asks you a few questions, and I hope that Lord Yin will tell you the truth." Yang Er took a sip of herbal tea and said softly.

"But it's okay for the prince to ask, the official should know everything."

"Then the king asks you, your Luzhou Mansion is the seat of Hedong County. The people's livelihood is safe and healthy, and the people are prosperous. Lord Cai has made a lot of contributions. But I don't know how much refined salt is stored in Fuchu? How much can the people in the market buy? Yang Er went straight to the topic of salt.

"Don't hide it from Your Highness, other states in this dynasty are short of salt, but because of the Yellow River waterway leading directly to Shandong, there are still salt merchants from Shandong in Luzhou. Therefore, there are thousands of catties of salt in the state treasury. However, there are not many sales in the market. In addition, the price of salt is too high, and ordinary small households cannot ensure that they can eat it. Cai Fuyin said.

"Then what is the price per catty of salt in Lord Cai's market salt?" Yang Er asked.

"Huh! If the prince is short of salt in the army, he can transfer it from my treasury. The waterway of the Yellow River is difficult and dangerous, many salt ships have sunk, and the long distance here, the price of salt has become gold, and the merchants seek profits, so even if there is salt for sale, the common people will not buy it, so that it can still be replaced by salt and stone. Cai Fuyin replied cautiously with a smile.

"This king has come here to solve the problem of the people's use of salt. There is a solution pond in Gulu Village, which is enough to mine refined salt for the people to eat. Yang Er got up and paced, whispering.

"Gulu Village is remote, and the water from the pond is inedible. I've never heard of salt. Lord, what are you 。。。。。 ”

"This king wants to open a salt field in Gulu Village, next to the Jiechi, and widely collect the salt from the Jiechi to relieve the suffering of the people of Beijing and Luoyang. I wonder if Master Cai is willing to help me? Of course, the first batch of salt should meet your needs in the east of the river. Enough for the parity! Yang Er said to Cai Fuyin with a smile on his face.

"This... I don't know what the prince needs to do? I hope to make it clear. Cai Fu Yin Xin said, can you not agree? You, the prince of Chitose, have opened a golden mouth in front of me. If you don't say yes, you can't do it! Salt mining in the pond is really a miracle through the ages! Let's have some blood to play with you, the young prince!

"I really only need one thing in your treasury, iron ingots. All iron ingots in stock. I don't ask for it in vain, I will make an IOU, and in the future I will deduct it with the equivalent amount of refined salt. Yang Er turned his back, didn't look at the rich and strange expression on Cai Fuyin's face, and said coldly.

"The prince is a thousand years old, and it is not a secret that in the counties of Hexi, mainly around Jinyang, there are many iron mines. Every year of war and Turkic invasion, each county government has a standing iron ingot, and every year Tang Gong transferred a lot of iron ingots from Jinyang to this county. Because the war has subsided for many years, it is difficult for the Turks to invade our county, so there are a large number of iron ingots in the prefecture. But if the prince Chitose wants to allocate iron ingots, he still needs to say hello to Shangguan, otherwise if the official knows about it, then the official will not be able to protect his head. Cai Fuyin followed Yang Er's footsteps and said.

"Hmm," Yang Er nodded, agreeing with Fu Yin's statement. Iron ingots are strategic materials and cannot be moved lightly until wartime. Unauthorized use of war preparation materials for profit, in accordance with the Sui law.

"Otherwise, I will write an explanation in the name of the Jin Wangfu and attach the king's IOU, and you can send someone to the Tang Mansion in Jinyang. I thought that you didn't have much iron in the treasury, and you still need to go to Jinyang to visit Tang Gong! I don't want you to have enough iron ingots, hehehe! Well, that's good! Yang Er turned around and said with a smile.

"That's so good! I don't know how much iron does the prince use for Chitose this time? The official is good to allocate the full amount. Cai Fuyin also sighed, thinking that this little prince was quite decent.

"Later, Pei Yun, the chief bookkeeper of my house, will present the list. You can just pay as ordered. If the king wants to stay in Luzhou for a few days, you can arrange a post house. ”

"This official obeys His Royal Highness's orders, and the accommodation and food arrangements are in place, Your Highness should not worry." Subsequently, Cai Mansion Yin Lingfu was engaged in leading Yang Er to the post house. Pei Yun also handed over the number of iron lists to Cai Fuyin. Fu Yin looked at it and breathed a relaxed sigh, the amount required was not too much, and he only needed to use one-sixth of the iron stored in the treasury. So he immediately arranged for a small subordinate in the house to cooperate with the supply. The matter was easily resolved, and Yang Er felt a lot more relieved. If you really go back and forth to Jinyang, which is 800 miles away, it will be a very sinful thing. Of course, the matter of writing is indispensable. Otherwise, it may really make Lao Cai's head unsafe.

Next is Pei Yun and his subordinates who are as busy as civil officials. Gathering blacksmiths, buying coarse cloth, buying charcoal, buying wood, etc., could not be done in a week. What Yang Er has to do is to take his personal escort soldiers to play around in the bustling Luzhou, and also take this opportunity to take a good look at the women of the Great Sui, it seems that they are not as open as the legendary Tang Dynasty, and there may be a reason for the northern climate! There are few girls and daughters-in-law, and it is no wonder that the real Yang Guang wants to go to Jiangnan when he has nothing to do. In the past few days, Cai Fuyin has been serving him with good food and drink, and he does not dare to have the slightest slackness and dissatisfaction. Yang Er was also full of praise for Cai Fu Yin's ability to come to things, thinking that he was a talent. All aspects are thought out thoroughly, and big and small things are done meticulously. After receiving the praise of King Jin Chitose, Cai Fuyin felt beautiful in his heart, and felt more and more that his official career was unlimited.

On the third day of Yang Er's stay in Luzhou, he received a letter from Pei Shiju, who had arrived at the Jiechi Lake in Gulu Village.

The letter said that the whole army had arrived at Gulu Village and began to explore digging wells to get water, and it was estimated that the water would be available within half a month. In addition, the garrison and the people have begun to build barracks, and the wood used to build the barracks is to cut down trees in the mountains in Xie County and Yi County or directly purchase dehydrated and air-dried wood from the timber shops in the two counties, totaling more than ten tons. It is enough to build a military camp and resettle a civilian camp. At the same time, the water quality of the solution pond was also investigated. The letter also specifically mentioned a person, this person named Liu Xuan, when the army passed through Yi County, the closest to Gulu Village, after hearing about the salt production in the pool, he took the initiative to join the army to participate in salt production. This person is proficient in engineering and physics, and he has also studied the method of drying salt, and this person is responsible for the investigation of the water quality of the solution.

Liu Xuan? Yang Er fell into deep thought when he saw this name. There are very few well-known people who can be called scientists in the entire Great Sui Dynasty, and I know that one named Zhao Chun is just the one who designed and built the "Zhaozhou Bridge", and there are not many other famous people. Could it be that this is one of the most famous "two Lius" in the Sui Dynasty, Yang Er only remembers that one of them is named Liu Zhuo, and the other person really can't remember, is it this Liu Xuan. If so, that's not a problem. This person is a scientific expert today, a doer, and knows the method of drying salt, so he is the general manager of the salt field, which is called knowing people and employing people in a good way.
