One gave Gongsun Hannan a great benefit.

A practical approach to coal.

In exchange, he successfully obtained the ownership of the high-level land on the edge of Tuyi Village, and it was the kind of Yongye Field, so their Liu family, in addition to the 400 hectares of cultivated land, also had a coal mining industry covering an area of about 50 hectares.

Moreover, Liu Yiyi also promised Gongsun Hannan that in the next few rainy days, the 'Liu's Coal Mill' would provide free coal for boiling water and rice to the villagers of several villages around Sanyuan County.

While earning a good reputation, it also made a resounding name for its own coal workshop, killing two birds with one stone.

Therefore, after obtaining the title deed of the coal mine from Gongsun Hannan, Liu Yiyi led the idle tenant farmers in the manor to Tuyi Village.

Braving the heavy rain, he built a huge straw hut on the high post, covered it with some oil-paper canvas, and began to dig up coal in it one by one.

After the excavation is completed, every time in a while, a carriage sent by the yamen will pull it away, and distribute it to those users who are in short supply of dry firewood, and hundreds of catties of coal will be pulled away in vain every day.

In this regard, Liu Yiyi does not feel distressed at all, there is giving, there is gain, this is like selling snacks on the street, let the guests taste a few bites for free in advance, reluctant to a little cheap, how can you attract others to buy your things?

Not only for the yamen, but also for all the big families in Sanyuan, Liu Yiyi almost all asked people to send a car over, of course. At the same time as sending coal to the past, it will also be accompanied by a copy of the use of Indy coal by the county, and there is an official certificate that the persuasiveness is not ordinarily strong.

In just one day's work, nearly one-third of the households in Sanyuan County have used coal to eat, and the word 'Liu's Coal Mill' has gradually entered their hearts. Before you know it. A coal mine brand. And so it was erected.

"When the rainy season is over, and the minerals are profitable, they will recruit another group of people, sign contracts, and pay them monthly, and these tenant farmers can't stay here forever." Liu Yiyi stood on the edge of the straw hut and watched as his tenant farmers carried baskets up the coal mine one by one. Whispered to Liu Wuchen on the side: "You can give priority to the villagers of Tuyi Village, and have the time to communicate with Nahong Village." ”

"Yes, young master!" Liu Wuchen bent over and replied lightly, following Liu Yiyi in the past two days, he can be regarded as having seen a lot of knowledge, and at the same time realized the true value of the coal mine bought by their young master.

It's a mountain of gold.

Simple, convenient, flammable. Liu Wuchen can almost imagine it. In the near future, all households in Datang will use this black stone.

The young master is a genius.

Before the farm implements, marketing methods. There is also the current coal fuel, not anyone can think of it, Liu Wuchen glanced up at their young master, and has been secretly congratulating him for the correct decision at the beginning, it is his honor to be able to become the housekeeper of the Liu Mansion.

"Well, okay, let's go back, here, there's nothing to do with us anymore." Liu Yiyi patted Liu Wuchen's shoulder, smiled and put on the rain, and walked out first, running in the rain for two consecutive days, he was really tired.

When he returned home, he learned that Feng Xiaoyi had led his subordinates to rush back, along with Li Ji and the two guards who had left behind before, Liu Yiyi nodded lightly, the hidden dangers over there of Hou Junji will not be born in the short term, it doesn't matter if they leave, and it is not appropriate to always let a team of guards who protect the queen stay in their own homes.

Back in his room, taking off his clothes, Zhang Chuchu hurriedly took out a set of clean underwear for Liu Yiyi to change into, and Xiaoxi went to the stove room to bring a bowl of hot ginger soup to get rid of the cold.

Holding a dry towel, Zhang Chuchu carefully wiped Liu Yiyi's forehead, the rain on his head, and whispered a little distressedly: "It's raining outside and it's cold, and my husband must have suffered a lot of sins by soaking in the rain all day long, right?" ”

"Hehe, how can the lady say it so seriously," Liu Yiyi put down the soup bowl in his hand, and said to his daughter-in-law with a chuckle: "The husband and Wuchen have not been in the rain for a long time, there is no big problem, the lady should not worry." ”

Saying that, Liu Yi grabbed Zhang Chuchu's little hand, gently helped her to sit down on the side, looked at Zhang Chuchu's bigger belly, and said softly: "It's the lady who should pay more attention, this rain and the road is slippery, if it's not necessary, don't go out again, and then teach Xiaohui to read in the future, just let that little girl come to our room." ”

How can you be so delicate, husband, you are too worried," Zhang Chuchu saw that Liu saw that his husband cared about him so much, and smiled sweetly.

"Young Master, Young Master Helan is here," In the distance, through the hazy heavy rain in front of the window, Xiaoxi saw Gongsun Helan walking towards this courtyard with an umbrella, so he opened his mouth to report to Liu Yiyi.

"Oh?" Liu Yiyi glanced out and laughed softly: "Don't worry about him, he will come in by himself in a while, and Xiaoxi will go and prepare a bowl of cups for him." ”

really responded to Liu Yiyi's words, and before Xiaoxi walked away, Gongsun Helan pushed the door and stepped in.

"Big brother, sister-in-law, little brother is polite here." With a big grin, he bowed to Liu Yi and his wife, and Gongsun Helan sat down under Liu Yiyi.

"Uncle is polite," Zhang Chuchu bowed slightly, returned the salute, and looked at Gongsun Helan with a hint of a smile in his eyes.

After Xiaoxi brought the tea, Liu Yiyi glanced at Gongsun Helan and said softly: "Brother Xian is here, but do you want to say goodbye to your brother?" ”

"Uh, big brother is a god, hehe," Gongsun Helan shook off the folding fan in his hand, chuckled and said to Liu Yiyi: "Originally, when Feng Xiaoyi and they were about to leave in the morning, the younger brother also had the intention of going, and after staying here for four days, the younger brother should also go back to have a look, otherwise the old man at home should be angry again." ”

"I already knew that you wouldn't stay here for long," Liu Yiyi nodded with a chuckle, looked at Gongsun Helan and said, "After I go back, say hello to Uncle Gongsun and Aunt Gongsun on my behalf, our two families are not far away, and we can often come over when we have time." ”

"That's what you call coal?" In the Taiji Palace, Li Shimin walked lightly to Gongsun Hannan, looked at the coal brought by Gongsun Hannan, and asked Gongsun Hannan softly.

"Yes, Your Majesty, the things of charcoal have existed since ancient times, and they are also very rich in my Tang Dynasty, but there has been no proper application method, and it has not been used by the world, and it is still buried among the mountains." Gongsun Hannan took out a piece of tissue paper from his arms, bent over and handed it to Li Shimin, and said: "Weichen has a side here, it is very convenient to ignite this charcoal and use it for daily needs, please take a look at it." ”

Dedicating this method to the emperor is the great benefit that Liu Yiyi gave to Gongsun Hannan, but obviously, Gongsun Hannan did not have that kind of meritorious mind, and while handing the method to Li Shimin, he did not forget to tell Li Shimin about its source: "This method is what Mr. Liu Yiyi Liu thought, and it has also been tried in Sanyuan, so there is nothing wrong with it." Now the rain is non-stop, dry firewood is difficult to continue, with this kind of charcoal, you can protect the previous epidemic prevention prescription worry-free. ”

"Oh? Another willow? Li Shimin took the paper, glanced at Gongsun Hannan, and remembered that the last epidemic prevention prescription was also handed by him, looking at his appearance, he really had a bit of a feeling of worrying about the country and the people.

Li Shimin glanced at the paper, but did not see anything unusual, handed the paper to Li Ran on the side, and asked him to make a short cylindrical shape of the charcoal and water brought by Gongsun Hannan according to the description on the paper, and then roughly inserted a few small holes evenly on it with a wooden stick, and put it on the fire.

"It's on! Your Majesty, it's really on! Seeing that the honeycomb coal was roasted on the fire for a while, and a fiery red flame came out, Li Ran replied to Li Shimin with a sharp voice, the burning stone, in his opinion, was amazing.

"Yes, it's really on," compared to Li Ran's excitement, Li Shimin was much calmer, he knew that this kind of coal could be ignited, but he didn't expect it to burn so violently.

That Liu Yiyi is really a talent.

It's a pity that such a talent is unwilling to contribute to the court, Li Shimin sighed lightly, with this method, it is indeed possible to solve the urgent need, not only that, whether it is daily life, or marching and fighting, with this kind of coal, it will be much more convenient.

"Gongsun Qing, I don't know where you got this coal?" Li Shimin looked at the charcoal balls that were burned red, and asked softly to Gongsun Hannan on the side.

"Back to the emperor," Gongsun Hannan glanced up at Li Shimin cautiously, and said, "These are all obtained from the 'Liu's Coal Mill', and the 'Liu's Coal Mill' was opened by Mr. Liu, who called this kind of coal 'coal'. ”

"'Liu's Coal Mill'?" Li Shimin's brows furrowed suddenly, no wonder Liu Yiyi's kid was so enthusiastic this time, and he made trouble for a long time, it turned out that he was waiting for me here?
