Datang Lingnan King

Chapter 61
"Grandfather, please look, these are cotton quilts and clothes made of white folds." After the meal, everyone was resting in the pavilion. Feng Daiwen took out a few quilts and cotton clothes that the workers had just made:
"Oh, it's really soft," Li Yuan stretched out his hand to press the quilt and said:
"Not bad, very light, very hot." Li Shimin put on the cotton coat and quickly took it off, saying:

"Hey, with this quilt, Grandpa Emperor, you only need two quilts in winter. You don't need to warm the bed and it will be very warm." Feng Daiwen looked at the 10-jin quilt in Li Yuan's hand and said:
"Oh. That's really great. I don't need to cover 7.8 beds of silk quilts in the winter. It's dead heavy and not warm. If it wasn't for warming the bed, I would be worried about freezing to death." Li Yuan said happily:
"Weiguo, this is cotton, right? Is it easy to remove cotton seeds? Can it be mass-produced? This thing is really good. I sweat profusely as soon as I wear it, and it's light. If I equip a lot of frontier troops, I can fight even in winter." "Li Shimin asked Feng Daiwen excitedly, Li Shimin is worthy of being an emperor through the ages, and he thinks about the soldiers and civilians first in everything.

"This is the white folded cloth of the Western Regions, which is made of cotton cloth with cotton in the middle. It is airtight and can keep out the cold very well. It is easy to make. It's just that there is not much cotton in the Tang Dynasty now. My son has already told the merchants in the Western Regions to buy a large amount. Cheng Chumo, Yuchi Baolin and others went to the Western Regions in person, there should be a lot of them this autumn, and I can plant them in Tang Dynasty," Feng Daiwen explained:
"Okay, very good, can I grow it in Datang?" Li Shimin was very happy with Feng Daiwen's arrangement, clapped his hands and said:
"It can be planted in the northwestern region of my Tang Dynasty, as well as in Guanzhong. I plan to bring the existing seeds to Shuofang to plant, and the cotton clothes are thick, and bows and arrows can't penetrate them far away. It's just that we need to prepare a lot of manpower now." Feng Daiwen said:
"No problem, Weiguo's arrangement is that, I want to see the results as soon as possible, and I need someone to recruit it." Li Shimin waved his hand and said:

"I want to ask my mother to choose maids in the palace and learn how to weave cotton, so that I can promote it from top to bottom. It just so happened that the subjects entrusted by the emperor to Guang'an have nothing to do. Chen intends to let them manage and learn how to remove cotton seeds and pluck cotton. I don't know what my mother thinks." Feng Daiwen said:
"That's right, I know that I feel sorry for Guang'an. After removing the cotton seeds, this cotton is similar to silk. Weaving is very simple." The eldest grandson looked at Feng Daiwen with a smile and said:

"He's a good boy, Guang'an is a lucky one." Concubine Wan Gui also chimed in and said with a smile:

"Uh, father and mother, please drink tea," Feng Daiwen and Guang'an both blushed, and when they saw the maid brought tea, they hurried over:

"Hey, Weiguo is not bad, you still have ice cubes now." Li Yuan asked in surprise:

"This is made of saltpeter, not stored ice," Feng Daiwen said:
"You, you, said that this ice was made." Li Shimin also asked in surprise:

"Yes, father, the son does not talk about strange powers, but in fact, many incredible things are passed on because of ignorance," Feng Daiwen said while asking for a water basin and saltpeter.
When everyone heard that Feng Daiwen was about to condense water into ice, they gathered around to watch. Feng Daiwen took the wooden basin and poured clean water into it, asked Li Shimin to test the temperature, and then put in saltpeter. Thin ice begins to condense,
"This,, this,, is really incredible," Li Yuan sighed:

"That's right, it wasn't Wei Guo who explained it in advance, so I never thought it would be the effect of saltpeter." Concubine Wan Gui echoed Li Yuan and said:

"It's just that this ice can't be eaten, but it can be used to cool off the heat and freeze items. As long as you don't put food directly on the ice, it's fine." Feng Daiwen put some saltpetre on it, and soon a basin of water turned into ice.

"You mean the ice made from saltpeter is poisonous?" Li Shimin frowned and asked:

"Father, in fact, as long as it is made of minerals, it is poisonous and harmful to the human body, but the human body can decompose toxins, and you can't see it when you take a small amount. On the contrary, you think it is a good thing, just like the elixirs made by Taoists with mercury and cinnabar." Feng Daiwen thought of Qin Huang and Han Wu's crazy alchemy in pursuit of longevity, so he explained carefully:

"I saw with my own eyes a Taoist priest who took elixir all the year round and came to life after death. What's going on?" Li Yuan asked:
"This is the elixir made from minerals all the year round. His body and blood are full of minerals, which attenuates his transformation. If the emperor doesn't believe it, you can use animal experiments to give him the elixir for a long time. When it dies, see if it takes a long time to rot, but reduce the dosage. If you increase the dosage, the animal will die immediately. The smaller the animal, the faster it will die." Feng Daiwen can't say that there is a lot of blood in his body Mineral toxins, slow growth of bacteria to explain, I have to use the reason that everyone can understand:
Li Shimin nodded and did not speak, Li Yuan's face became a little ugly,
"However, if you take it in a small amount, as long as you don't take it in the future, eat more vegetables, and you'll be fine. If it's ice water like this, we can drink it." Put on a bowl of tea, wait a while for the ice in the bowl to condense, then drink it, "It's comfortable," Feng Daiwen smiled in satisfaction,
"Brother-in-law, brother-in-law, I want to drink too," Chang Le and the others ran over and shouted anxiously after playing hot:
Feng Daiwen quickly froze the water of the tea and gave it to everyone, "You can't drink too cold if you run hot, just freeze it a little bit."

"I've met the Supreme Emperor, the saint," sending Yuan Tiangang away, who was in a hurry to gather people. Ma Zhou brought a few guards carrying two stoves, one large and one small, and the guards came over carrying a box of black coal.

"It's done so quickly?" After Ma Zhou saw the ceremony, Feng Daiwen asked unexpectedly: "I couldn't help but feel happy for the craftsmen of Datang. They are really amazing. They made samples quickly with just a few hints.

"What is this?" Li Shimin looked at the stove and asked in confusion:
"Father, this is a good thing. With this thing, it is much more convenient. You can have hot water at any time, and you can also save fire." Feng Daiwen said happily while having someone bring a fire to light it for trial use:

One of the two stoves is a single-hole stove, and the other is a three-hole stove. As the coal was finely ignited, it ignited quickly. After waiting for a long time, a raging flame ignited. There is a cork made of wood on the top and bottom. When not in use, the flame on the bottom will be small. "If a coal block is plugged on the bottom of this fire, it can be managed for 3 or 4 hours. Even for cooking, ordinary families only use one Coal," Feng Devin explained:
"Yes, it's a good thing. In the future, poor families can have hot water at any time, and they can sit around the fire in winter, but how to solve this carbon poisoning?" Li Shimin even if Li Shimin's first consideration is the people,
"Just put it in a ventilated place, as long as the room is well ventilated, there will be no problem," Feng Daiwen replied:

"That's right. When I was in Taiyuan, I've seen two carbon-poisoned people with closed doors and windows." Li Yuan thought for a moment:

"Okay, okay, Wei Guo is really my good son-in-law, haha" Li Shimin laughed happily:
"Father, this charcoal is also called coal. Father sees who will be in charge of mining it. My son has only bought two small mines. Taiyuan has the most of them," Feng Daiwen said:
"Taiyuan?" Li Shimin frowned:
"Yes, there will be a large demand for this product in the future, so it's better to control it, but it can be handed over to others for mining, and the state is responsible for production, just collect taxes." Feng Daiwen said:
"Give it to others to mine, isn't it controlled by others," Li Shimin said:
"Yes, the government only needs to send people to supervise the amount of mining and not abuse the power of the people. It is best to use captives for mining. For example, it is stipulated that there is less tax for mining with captives. Only mining can be done, and another company must be used for production. There will be chaos, and there is not only one place in the country where it is produced, if you are not satisfied, you can make it impossible to sell it." Feng Daiwen said with a sinister smile:

"Haha, haha" Li Shimin laughed happily:
"Haha, haha" Li Yuan figured out the key point, looked at Feng Daiwen and laughed loudly at the same time:
