"Pei Gong, Mr. Chief Bookkeeper, I put the local government soldiers in charge of Mr. with the intention of letting them go here and around to find the origin of this black stone. The black stone smoke is thick and choking, that is incomplete combustion, and when it is fully burned, the black smoke will be gone, and the firepower is sufficient, which can be used to smelt refined iron into steel. Many of today's weapons can only produce wrought iron because of insufficient firepower, and the hardness is not enough, so the weapons created in this way are easy to break when fighting. Yang Er slowly explained to Er Pei, Er Pei couldn't help but nod when he heard it, and slowly felt that this black stone was a good thing.

Yang Er continued: "Mr. Pei is right, now the black stone is only found in the northern wilderness, and it was discovered by the Turks in advance, but the Turks are stupid and don't know the use of the black stone. In fact, as far as this king knows, there are many black stones at the foot of the Tang Dynasty in Shanxi, but the depth of the burial is different. The black stone in the hands of the Turks must have been bare or only a few feet deep in the place of origin, and it was very easy to obtain. ”

"Then the lord means that I should wait north to mine the black stone? But what a long way to go! The horsepower is unbearable! Pei Gong couldn't help but sigh at this time. He now knew that the black stone was indeed a good thing, and could be used to smelt steel, and the old man knew the value of the black stone at once.

"No, Pei Gong. What does it mean to leave the black stone in front of you and not dig it? Yang Er said with a smile, and at the same time, took a sip of the tea on the table.

"Is there a black stone nearby?" Pei Gong and Pei Yun asked almost at the same time.

Yang Er walked to the front of the desk and unfolded the Hedong atlas he had drawn, pointed to a point on the map and said: "Look, this is here, according to this, it is not very far away, when it is in Zezhou, east of Wenxi County, on the west bank of the Dan River, there are shallow black stones that can be mined." Master Pei, you can arrange for a shrewd and capable person in the army to specialize in this matter. Won the Zezhou Blackstone Mine Prize. I think that the old fairy who is a monk with dead leaves will not deceive me! "Yang Er must let this enlightened monk and ancestor come out to endorse him, otherwise he can't tell why he knows about the coal production in Naze Prefecture. As early as in junior high school, in geography class, Yang Er knew that there were several major coal-producing areas in Shanxi, and Shanxi Jincheng was one of them, and this Zezhou was the approximate location of Jincheng in later generations. Due to the changes of the city for thousands of years, the location of Zezhou is not necessarily the location of Jincheng in later generations, but it is generally not bad here.

"Is there a black stone in Nadan River? Okay, just ask one person to find out. Pei Gong laughed when he heard this.

"The person Pei Gong said is not the same family master Zheng Gong who is not far from the north of Zezhou?" Pei Yun guessed. He knew that Jicheng, where Zheng Fengchi's family was located, was not far from the Dan River in the south, so he guessed.

"Exactly, it's very easy to leave this matter to Elder Zheng." Pei Gong said with great certainty.

"Okay, Your Highness, your majesty will arrange it. When the prince returns from Beijing, there will be good news at that time. Pei Yun got up and bowed to Yang Er.

"Okay, when the king is not here, I bother to ask Pei Lao to take care of it. In addition, Mr. Pei also has to arrange people to go to the surrounding areas of Hedong to explore the black stone, and the more black stone mines, the better! After Yang Er finished speaking, Er Pei got up and gave the order, turned around and walked out of the big tent.

Yuwen Chengdu stared at Yang Er like a monster, Chengdu was not good at talking, and when the three of them discussed, they couldn't interject at all. It's okay to talk about martial arts, but when it comes to government affairs and economics, he doesn't understand it at all.

"Alright, Brother Xian, let's get ready for the campfire barbecue party in the evening!" Yang Er's face was relaxed, and he stepped out of the big tent under the escort of Yuwen Chengdu's eyes.

This return trip was accompanied by Yuwen Chengdu, and Yang Er was called a down-to-earth person in his heart. Laihu'er no longer has to follow left and right, but leads 50 cavalrymen holding high the banner of the word "Jin" in front of 100 meters Yang Er and Yuwen Chengdu are in the middle in parallel, followed by 20 personal generals, Yuwen Chengdu's guards also follow behind, and they can be distinguished from their clothing. Followed by a hundred elite Jin Palace's entourage guards. The whole team is more than half as small as it was when they left. But all of them are cavalry, and their combat power when they encounter the enemy is much improved.

Yang Er talked and laughed with Yuwen Chengdu along the way, talking about childhood troubles. also asked a lot of Yuwen Chengdu's experience of practicing martial arts with his master Yujuluo, but in his opinion, the pain is far greater than the happiness. When Yuwen Chengdu talked about practicing martial arts and being punished by his master, the more Yang Er laughed wildly, and the angry Yuwen Chengdu rolled his eyes and didn't want to continue.

Yang Er saw that Yuwen Cheng was ignoring him, so he took a few deep breaths and finally calmed his mood. Then, I took Yuwen Chengdu's weapon: the phoenix wings and gold hammer, and I felt very heavy in my hand. Yang Er's arm strength has increased a lot when he came to this era, and he has been working hard every day for several months, which is said to be a 300-pound divine weapon, although his hands are heavy, he can still hold it. This weapon is really not ordinary in Yang Er's eyes, it is more than a zhang long, there are three blades in the head of the blade, the blade in the middle is wide and straight, the blades on both sides are slightly shorter, and a small wing arc forward is born outside the side blade, making the entire battle part of the front wide, like a rake, and a red cherry whisker is wrapped between the rod, which is to block the blood flow of the enemy to the rod. The rod is two meters long, the mouth of the cup is thick, which requires a pair of large hands to grip, and the end part is a puff about a foot. The entire body was covered with a layer of gold dust, and the divine weapon radiated a golden light in the sunlight.

After Yang Er finished looking at this weapon, he couldn't help but admire: "This weapon is not a mortal weapon, and it is not available to non-gods!" Yuwen Chengdu, who was originally depressed, couldn't help but raise his chest and laugh after listening to it. I thought to myself, this boss has just destroyed my existing weapon and compared me to a god descending from the earth, which is really unusually useful. Yang Er looked at Yuwen Chengdu laughing with disdain, this guy is really coaxing!

The front suddenly rode to the front, and the immediate general was Liang Shitai, who arched his hand and said: "Lord Chitose, 10 miles ahead is my hammer village, and the farmers are now on the side of the road in front to greet His Highness." ”

"Okay, Chengdu will come with me." With that, the reins of the horse rushed out of the queue, and Yuwen Chengdu then rushed to the forward open road camp horse team.

Yang Er, who was far away, had already recognized that the old man standing in front of the crowd was Uncle Liang, and at a distance of nearly 10 meters, Yang Er and Yuwen Chengdu both reined in the horse's head, and then jumped off the horse and walked towards Uncle Liang.

Uncle Liang Sanshu led all the villagers to kneel down to greet him, and the mountain called the king of Jin for a thousand years. Yang Er returned the salute and beckoned everyone to get up and speak, at this time Yang Er was most concerned about the growth of several crops he left in the village, according to the calculation of normal days, plus the sunshine during this period of time, it can be said that the wind and rain are smooth. My sweet potato and potato crops should be yielding.

After Yang Er's polite words were finished, Uncle Liang turned around and asked a few young men to move over a few big back baskets, and said: "Look, the new thing planted by the prince himself a few days ago has already had the first harvest a few days ago, please take a look." ”

Yang Er hurriedly stepped forward, only to see that there were three baskets of pale yellow potatoes, all of which were huge. Yang Er was very surprised, the potatoes in later generations were different in size even if they grew from the same vine, and these baskets were similar in size and shape. I took out one and put it in my hand and weighed it, and there were three or four taels.

"Third uncle, this potato is growing well, how much has been harvested?" Yang Er asked, putting down the potatoes in his hand and looking at the other baskets of sweet potatoes.

"Lord! At that time, more than 200 plants were planted, and each seedling harvested nearly ten catties of fruit after it grew up. The whole harvest of this potato is nearly 2,000 catties! As the prince said, this thing is really a high-yield grain. Third Uncle Liang was already excited at this time.

"Have you ever eaten cooked food?" Yang Er turned around and asked again.

"Lord Wang, without your will, Xiao Min'an dares to steal food, a capital crime! If the prince doesn't come, Xiaomin is preparing to send this thing to Luzhou! Uncle Liang said cautiously.

Yang Er picked up the sweet potato again and weighed it in his hand, and couldn't help but feel inexplicably abnormal in his heart, why did this sweet potato and potato grow so big, and the weight of this sweet potato in his hand was at least half a catty, which was quite heavy. What's going on? Damn, the manpower and weapons of this era are heavy, which may have something to do with the living environment. How is it that the grain produced in the field is more than the Hereafter? Moreover, later generations also used the crystallization of various scientific and technological achievements - fertilizer. Could it be the reason why the air in this world has a high oxygen content and is free of all kinds of pollution?

"Third uncle, how is the yield of this sweet potato?" Yang Er came to his senses from puzzlement and asked again.

"According to the planting method instructed by the prince, the planting of sweet potatoes has been divided three times, and now here are the results of the first two plantings, about 3-4 thousand catties. After several rounds of planting, there are still more than 20 acres of unripe sweet potatoes in the field. This thing is very easy to maintain, easy to grow and grow, and the villagers have been skillfully planted and planted. Uncle Liang touched his beard and said very happily.

Yang Er looked around at the Zhuang men and women around him, and saw that all of them had bright smiles on their faces.

"Third uncle, have you ever shared this sweet potato with the villagers to taste?" Yang Er asked. I really hope that these honest people have already tasted sweet potatoes.

"Lord! The little old man has already said that without the order of the prince, all the results have been collected and stored, and even the little old man has never eaten a penny. Third Uncle Liang looked at Yang Er and said with an oath.

Yang Er sighed in his heart, the monarchy in this feudal society is not all bad, and the people under this strict hierarchical system really abide by etiquette and dare not cross the thunder pond by half a step. The innocence of human nature in this era really moved Yang Er from later generations and blushed. Has humanity degraded over time?

Suddenly, a rooster crows from the crowd. Yang Er looked up, only to find that several coarse cloth women in the crowd were holding a pure white rooster with a big red cockscomb in their arms. Yang Er was happy again, he could feel that this was not a chicken that could be found in this era. Seeing Yang Er walking towards him, these women hurriedly stood up and raised the chicken in their hands to Yang Er, with a happy look on their faces.

"Auntie, this chicken is my egg... Phew, but the eggs I gave you and others hatched? Yang Er's face was embarrassed. A few of the near-forehead posteriors were holding back a laugh. Uncle Liang stepped forward and waved at these young men. Suddenly, the faces of the descendants returned to their normal smiles.

"Back to the prince's words, the rooster in the hands of the woman is hatched from the eggs left by the prince. The egg production of hens is very high, and a chicken can lay eggs almost every day from the beginning of its own eggs, which is amazing this year! Now every household in the village is feeding this kind of chicken, as few as a dozen, and as many as more than 100. "This Zhuang woman, when it comes to raising chickens, she can't stop smiling. Several village women behind him were also overjoyed. Yang Er deeply felt the diligence of the people in this era at this time. The more than 100 eggs left by himself have already bred thousands of chickens, and they are still in the non-stop laying of eggs and chickens. It is conceivable that even worthless things such as sweet potatoes and potatoes are reluctant to eat, and eggs are even more reluctant to touch.

"Good, good! Third uncle, call the villagers and elders to go back to the village. Yang Er followed Uncle Liang, Liang Shitai and others all the way back to the village. Yuwen Cheng didn't understand what was going on, it seemed to be something that made everyone very happy. But he didn't feel it, just silently led the two horses and followed behind.
