It is said that in the 18th century, a Chinese merchant returned from Burma with his little donkey. At that time, he had not much goods, so in order to balance the goods on the little donkey's back, he picked up a stone from the ground and put it in the cargo frame on the donkey's back to make a counterweight. When I got home, I naturally threw the counterweight stone in my hand...... Then, the stone broke open, revealing the crystal clear green jade inside.

As a result, jade mining in Myanmar was discovered and quickly attracted countless miners.

All over the world, only countries and nationalities in the Greater Chinese cultural circle that are deeply influenced by Han culture will be interested in jade. On the basis of history, there are four major jade producing areas in China, which produce Hetian jade, Lantian jade, Dushan jade and Xiuyu. Among these four types of jade, Lantian jade was developed and applied at the earliest time (the jade seal of the country is Lantian jade), but after Zhang Qian's passage to the Western Regions, Hetian jade, as a relatively simple color, white and transparent nephrite, was quickly recognized by the Chinese upper class. Its status in China's jade culture began to flourish. However, due to this era, the Han family is engaged in self-mutilation, so the Han people's control over the Western Regions is extremely weak, and the production of Hetian jade is also very small.

Specific to Guan Yi's point in time, before the Wei and Jin dynasties, jade was mainly used for ritual vessels. It is occasionally used as an ornament, but only to show the identity of the wearer. From the Wei and Jin dynasties, Chinese jade began to be used as a wear item, and gradually from the ruling class to the people. Therefore, it is very interesting to mine and sell jade during this time period.

The unique Burmese jade, as well as the real jadeite, sapphire, and ruby, have not yet been discovered and developed by anyone. If he is mined in this era. Well, this is Shuhan's new fist product again.

"Bow down, my Han Dynasty has served as the governor of the city, and your grandfather is the most respected by the people of Nanzhong. We've been all the way this time, and we've seen it. As soon as I heard that Ma Zhennan's grandson was coming, all the villages along the way opened their gates and greeted and entertained us with the highest courtesy. Therefore, in the seven counties of Nanzhong, your bloodline is much better than the official position of this official. Therefore, this official needs you to stay here for a long time and build this place into a large jade city. ”

"Please rest assured!" Ma Yi didn't even ask Guan Yi why he said that there were large jade and gem mines here—Guan Da Sima's fingers were metallic. He said that where there is something underground, there must be something. There is a consensus within the Shu Han government.

"Da Sima, the lower officials must take root here with peace of mind. Recruit the local natives and dig up the jade and gem mines in the area. This is not only to make money for the treasury of my Han Dynasty, but also to make a living for the people in this mountainous area who have never been able to eat and clothe. This is also what I, the grandson of Ma Dexin, must do for the people of Nanzhong! ”

"Good. When I return to Chengdu, I will send you a small army. Later, military control was implemented here. In addition, after the first batch of jade mines is produced, I will also open up the right to purchase jade to domestic families. In the future, the production will belong to us, and the transportation and sales will all belong to the families. ”

Hey, hey, I heard Guan Yi say that. Ma Yi, Wang Ji and even Lao A and others all laughed wickedly: In the past two years, the great Sima of his own family has made the family in Shu Han want to die, and the high (anti-harmony) tide has been wave after wave: once you want to give the family a little benefit, there will inevitably be a new policy to cut the flesh of the family - and vice versa.

But then again, if this is really a brand new jade species according to what his own great Sima said, there is no doubt that this will cause the madness of all the families of Shu Han. No, to cause the collective madness of the entire upper class of the Three Kingdoms. At that time, whoever cooperates with the reform of his own big Sima will have the right to buy, and those who do not cooperate will go coolly......

"This place." Guan Yi knocked on the map of Yongchang County's county governance Buwei County: "This place is very important. In addition to using this as a base to build a jade industry chain. Kong Shuo (Wang Ji) will also use this as a base for activities in the next few years. ”

"Hehehe, Da Sima, are you finally going to use it?"

Looking at this person on the historical plane, he first sailed to Japan on behalf of Cao Wei and announced that the Yamatai Kingdom was a vassal of the Wei Empire. Follow Biqiu Jian to pursue the Goguryeo royal family for thousands of miles, and have been fighting until today's super bull of Leshi Jigong in Xiaoxinganling. Guan Yi's mood is also very complicated.

"How are Kong Shuo and my big man okay in the past two years?"

"Lao Da Sima cared about me and brought the whole family for me. In the past two years, Wang Ji has lived well in Chengdu. It's just that there has been nothing specific to do, so I can only go to the Fuxing School to learn all kinds of agricultural knowledge according to Da Sima's order. It was an eye-opener for me, but after all, I was a hard worker, and I wasn't fit to sit in a house all day. To be honest, in the past two years, everything has been good, but the whole body is almost rusty when it is idle. ”

"Hahaha~~ Kong Shuo is about to get busy. Well, Kong Shuoke still remembers the hybrid rice that the official talked about in the Fuxing School before? ”

"Remember!"

"Well, the rice seeds on the Chengdu Plain of my Han Dynasty are mainly from the ancient Shu Kingdom, which is indica rice. Its advantages are good taste, large ears of rice, and naturally large rice grains. The disadvantage is that it is not cold and drought tolerant, and the yield is not high. And in the Nanzhong rice system represented by Qiqi County, it is glutinous rice. It tastes better, but the yield is lower. The advantages and disadvantages of these two main rice varieties are very consistent, so the new generation of rice varieties crossed with these two rice varieties actually has no obvious advantages compared with the old rice varieties. ”

"Kong Shuo, please come and see." Guan Yi's finger pointed to Yutu again: "The east and west sides of Buwei County are large rivers running north-south. The one on the east side is Cangshui (the upstream is the Lancang River, and the downstream is called the Mekong River). In Buwei, along the river valley, from this to the south, you can go directly to Linyi, Zhenla and other countries. There is nothing to say about these small countries, poor and weak. The official is not interested in their land now. But they have a rice seed there, and it's Indica. The taste is average, but it is superior to high yields, drought tolerance, and does not require much from the fields in which it is planted. So Kong Shuo's first task was to go south along the Cangshui River to find high-quality rice seeds over there! ”

The high-quality rice varieties mentioned by Guan Yi are the famous Champa rice on the historical plane. This rice variety entered China during the Five Dynasties period and was later vigorously promoted by the Northern Song Dynasty government. Rice varieties native to China have been greatly improved. Taking the Chengdu Plain as an example, the rice fields of the Chengdu Plain in the Shu and Han dynasties produced ten stones per mu. However, after the introduction of Champong rice in the Northern Song Dynasty, the highest peak output value was two seasons a year, with a total yield of 30 stone per mu.

As an agricultural student, Guan Yi has long been accustomed to the value of 30 stone (800 kg) per mu of rice in a single season in modern society. Therefore, after crossing over, he was extremely dissatisfied with the current situation of generally producing five or six stones per mu. But in the past, he was busy preparing for Cao Wei's war to destroy the country, so he didn't have time to do this. And now, he finally pulled out his hand.

"If Kong Shuo can retrieve such rice seeds, this official is confident that he will expand the area of rice fields in Dahan by more than fifty percent, and increase the yield per mu by more than three times!"

"Hiss~~~" As a monster that has repeatedly shown magic, everyone present did not doubt the authenticity of Guan Yi's words. So when they heard such data, they were all shocked.

"And here." After Guan Yi gave the group of guys a little time to digest, he pointed his finger to the west side of Buwei County. "The big river on the west side of Buwei County is called the Nu River (the lower reaches are called the Salween River), and from there, you can go south to the Nanyang (the mouth of the Nu River is in the Bay of Bengal). Further west of the Nu River, there is a large river called Lishui (Irrawaddy River), which runs through the entire territory of Chenli (ancient name of Burma). From there, head south to the mouth of the sea and then go west. to enter the Kushan Empire. The country is strong, and Buddhism flourishes. Let's not talk about him, the key is that the rice seed in this country is the best rice seed in the world, if it can be brought back to the Han Dynasty and crossed with various rice varieties...... And there is another crop in this country, called sugar cane. With this thing, I will be able to make the people of Dahan all over the country eat sweetness! ”

"Ladies and gentlemen, never underestimate the power of trade routes, as long as there are enough benefits, any moat is a path. Four hundred years ago, when Bowanghou (Zhang Qian) went to the Western Regions, he saw bamboo canes and silk produced in Yizhou in the Dayue clan. From this, Bo Wanghou knew that there must be a trade route out of the mountains in the southwest mountainous area of China. Where is this trade route? Yes, there is! ”

Looking at the people who had fallen into a stupor, Guan Yi patted Wang Ji on the back: "Kong Shuo, if you do a good job here, the history books of future generations will record: Ma Yizhi, the first person to mine jade and jade, the beauty of a gentleman, bow to it." And if you do it well, well, it will be recorded in the history books: Wang Qi, introduce high-yield rice seeds, and raise the people of China! ”

Go down in history! There is no need for any more mobilization. Ma Yi and Wang Qi both kowtowed to Guan Yi with red eyes: "Da Sima, thank you for pointing out such a clear path for us." We dare not exhaust ourselves, and then die! ”
