The eldest grandson Wuji and Fang Xuanling, who got the answer, are about to retire. "Zhao Guogong, Lai Guogong is slow, I just have something to discuss with the two of you," Feng Daiwen hurriedly stopped.

"Oh, what's the matter with Weiguo, but it's okay to say it, the old man listens," Fang Xuanling said kindly.

"Sage, please take a look at the two princes," Feng Daiwen took out the clay pot he brought and opened it.

"It's a fish, what is it?" Li Shimin looked at it and asked.

"Hui sage, this is made of sea fish and pig and mutton, first cook the meat, dry, add salt, mustard, ginger, etc., can be used for marching meals, can be preserved for more than half a year, these are the vegetables of the sea, respectively, kelp, seaweed, sea cabbage, dried, only need to be soaked in water to cook to eat, and fresh, not only can be preserved for a long time, but also very convenient to transport." Feng Daiwen introduced them one by one.

"Yes, it can be kept for so long, it is a good food on the march," Li Shimin also has been on the battlefield for a long time, and naturally understands the benefits. "Spread my will, the Lingnan area procured a large number of them, and had their own rewards after the war,"

"The ministers understand,"

Li Shimin thought for a moment and said in embarrassment: "Defend the country, collect and make this sea vegetable, and give it to the coastal people, so that they can also have one more food and a little income." ”

"Yes, the ministers will arrange for people from Lingnan to teach, and ask the saints to arrange for them to go to the place." Feng Daiwen agreed without hesitation.

Li Shimin looked at his son-in-law with satisfaction, Fang Xuanling was amazed, and said: "Defending the country is broad-minded, and ordinary people are not as good as many. ”

"Fang Gong has won the award, by the way, this time the military ration can be ground into powder, add oil and salt before the war, stir-fry, add milk powder on the way to the march, boil it with water to brew and eat, and it is also full, Fang Gong can let people try how to make the taste better." Feng Daiwen suggested.

"Weiguo is really caring, I think there was so much convenient food in the war back then, it was all some dry food, coarse grain, just starve people and don't die, but now it's right to have time to prepare a little as much as possible." Li Shimin sighed.

The eldest grandson Wuji and Fang Xuanling also nodded with affection. "Weiguo, the old man has something to ask for," Fang Xuanling wanted to talk about it several times today, and when Feng Daiwen said that he couldn't help but say in embarrassment.

"The house has something to do, but it doesn't hurt to say it, and it will definitely be done if it can be done in the future." Feng Daiwen looked at Fang Xuanling curiously, no wonder he was very kind to himself today.

"Cough, the old man and his second son are loved, they are stupid by nature, they don't like to study literature, so they have a lot of strength, the old man and the literati really can't do anything about him, I want to ask Weiguo to take him with him to discipline him, you are all people of the same age, you should be able to play together, how can it be better than him all day long, please." Fang Xuanling said and saluted Feng Daiwen.

Feng Daiwen hurriedly avoided it, "Fang Gong can't be like this, but the hearts of parents in the world, the younger generation must try their best to teach their beloved brothers," bereaved love, Fang bereaved love, Feng Daiwen thought about this celebrity through the ages, but it was his wife, Gao Yang, who was only a few years old now, couldn't help but have a big head, hoping to change their fate.

Fang Xuanling grinned happily when he heard Feng Daiwen agree, Li Shimin rarely saw Fang Xuanling so out of shape, patted him on the shoulder and took out a map and said, "Wei Guo, this is a map of your home, explain it to me." ”

Feng Daiwen couldn't help but be stunned when he saw this unfinished map, and then remembered that it was piled up with other maps and was taken out by Li Jing casually, so he stepped forward and said, "This is the land we live in." The ministers and paintings are complete, and many places have not been to them. ”

"Is it a mistake to defend the country, we are only in such a small place in Datang!! The eldest grandson Wuji was taken aback.

"Zhao Guogong, you read that right, Datang is indeed so big, there are many bigger places in the world than Datang now, and there are many places that are richer," Feng Daiwen said with certainty.

"What's on the edge of the continent? Chaos? Did the Guardian ever know. Li Shimin asked with interest.

Feng Daiwen picked up the map and gathered in a circle and said: "Actually, the earth where we are is a ball, just like the sun and moon in the sky, and this ball is diagonally rotating around the sun, but it is too big to feel it. ”

"This,,This,,It's incredible, but there is evidence." Several people were wise people in the world, and they did not object, and the eldest grandson Wuji asked.

"The grassland is endless, but we are the first to see the heads of the people who come from afar, and the first to see the sails of the ships coming from the sea," Feng Daiwen said, gesturing on top of a clay pot with a cup.

"So, you said we were on a spinning ball, why didn't we fall?" Fang Xuanling rubbed his forehead and asked.

"It's a lot of reasons, there's the pressure we breathe gas, there's the attraction of the earth, and it also explains why some places are hot, some are cold, and if it's a piece of land, the temperature difference shouldn't be so big." Feng Daiwen explained in plain language as much as possible, otherwise talking about atmospheric pressure and the earth's gravity would probably be regarded as a neurosis.

A few people thought about it quietly, and also thought that Feng Daiwen was reasonable, Li Shimin looked at the map and said with bright eyes: "I didn't expect that the Central Plains is only so small, and there is such a big place outside waiting for me to conquer, haha," Looking at this big map, Li Shimin's restless heart was activated.

Although this is not deliberately taken out by Feng Daiwen, it is always a good thing for Datang to be able to let Datang's high-level officials understand the world, and not to keep staring at this one-third of an acre of land, and it is also an unexpected gain.

"But it's too far away, this is the big uninhabited island, with countless wild cattle and sheep, horses, rich mineral deposits," Feng Dewen said, pointing to Australia.

"Ahh It's actually more than twice as big as the current Datang," Eldest Sun Wuji said in surprise with a gesture of his hand.

"Yes, there is also this continent, which is full of people with stone weapons, which is equivalent to our Shang and Zhou Dynasty ago, if we can go there and let Confucianism and Taoism go to educate, it will be a good source of population." Feng Daiwen thought of the Indians on the American continent now, isn't that the best object of conquest, and many of the same yellow people are more acceptable than Westerners.

"This is what Aiqing said about the place where there is gold to build the city?" Li Shimin stared at the map and asked.

"Yes, what Master Gu said, it may be the descendants of the ancient remnants who inadvertently went there to combine with the local natives." Feng Daiwen recalled the controversy about the origin of the Indians in later generations.

"It turned out to be my Chinese relics, and I must let them return to their homeland in my lifetime," Li Shimin said with a righteous and righteous face.

"The saint is wise, and the ministers will help to complete the meritorious deeds," several people hurriedly complimented.

"Haha, with the help of all Aiqing, I will definitely be able to make my wish come true." Li Shimin looked up to the sky and laughed happily.
