After brushing his teeth, Tang Qi led the three of them to the east side of the wooden house.

When he arrived in front of a sweet potato field, Tang Qi pointed to the field and said, "Now, this field is full of sweet potatoes, you pull a little sweet potato and bring it back to me, I'll go and make a fire first!" ”

"Wait!"

Liu Che stopped Tang Qi and said, "Mr. Tang, didn't you say last night that you were going to make sweet potatoes?" Why did you let me pull this sweet potato again? Isn't it ready for a change of dishes? ”

Tang Qi was almost so angry that he spurted blood: "Isn't it, do you still need to act at this time?" Sweet potatoes are sweet potatoes, big brother! ”

Liu Che suddenly said: "I see, but I am lonely and unheard!" ”

"Okay, you guys pull it out quickly, I'll go live first!"

After Tang Qi finished speaking, he walked quickly to the wooden house stove.

The fire in the stove is extinguished every night.

After all, the forest vegetation on the island is too lush, and if he accidentally catches fire, Tang Qi will have nowhere to escape.

To be on the safe side, it's better to extinguish it.

As soon as Tang Qi left, Wei Qing couldn't help but say, "Your Majesty, this land is full of green, and it is called sweet potato, why don't you see the fruit?" ”

Sweet potatoes were only introduced to China during the Ming Dynasty.

So for the people of the Han Dynasty, sweet potatoes were a completely foreign thing.

Liu Che is well-read, and he doesn't know what this sweet potato is.

However, in front of Wei Qing as a courtier, Liu Che still said cheekily: "Didn't you listen to Mr. Tang, this sweet potato is also known as red vegetables, that is, a type of vegetable, and it is normal to have no fruit." ”

Wei Qing nodded, and then said with admiration on his face: "Your Majesty, you know so much!" ”

Liu Che laughed and said: "It's nothing, read more, you can also understand a lot of things!" ”

At this time, Wei Zifu said: "Let's not waste time, hurry up and pick this red vegetable, Mr. Tang is still waiting to use it!" ”

"Yes, yes, yes!"

Liu Che nodded again and again: "Let's hurry up, the sweet potato is delicious when I hear it, I can't wait to taste it!" ”

After speaking, Liu Che took the lead in running to the field and began to pick.

……

Tang Qi crouched in front of the stove and collided with the iron and flint, striking sparks that ignited the haystack in the stove.

Flint is the ancient flint, also called fire saltpeter, which is naturally formed.

The iron block was smelted by Tang Qi with sand and gravel at high temperature.

As for the early high temperature, it was naturally a stupid way to drill wood for fire.

Without further ado, Tang Qi took a lot of effort to finally light the fire in the stove.

At this time, I saw Liu Che and Wei Qing rushing over with a ball of emerald green.

"Mr. Tang, we have already picked the red vegetables you want, are these enough?"

Liu Che asked Tang Qi excitedly.

Tang Qi looked at the emerald green in the hands of the two, and then looked at the excited expressions of the two, and almost scolded his mother.

"What are you doing? I told you to pick sweet potatoes, what are you picking a ball of sweet potato seedlings for? Play me? ”

Tang Qi was about to despair, feeling that he had been played badly.

Liu Che's eyes widened and said, "Isn't this just red vegetables?" We picked it in the field you designated, Mr. Tang! ”

Wei Qing followed and said: "Yes, there are no other fruits in the ground, only these!" ”

I'm Nima!

Tang Qi rubbed his eyebrows, held back his anger, and said, "Who let you pick the ground?" Sweet potato, sweet potato, of course, grows in the ground! When you pluck the sweet potato seedlings, don't you see the sweet potatoes underneath? ”

"Pour ...... I did see a few! ”

Liu Che smiled awkwardly and said, "I thought it was an inedible rhizome, so I threw it away, so it turned out that it was a sweet potato?" ”

Tang Qi said helplessly: "Big brother, everyone is an adult, don't play this kind of childish game, don't you know what sweet potatoes look like?" Didn't you eat it when you were kids? ”

Liu Che shook his head very sincerely and said, "I really haven't eaten sweet potatoes, and I haven't even heard of them!" ”

Wei Qing followed and said: "Wei is the same, I have never heard of the name of sweet potato or sweet potato!" ”

"You ...... Alas......"

Tang Qi sighed and said, "That's it, I'll go with you, let you be a primary school student today, and I'll do popular science for you!" ”

After speaking, Tang Qi walked quickly towards the sweet potato field.

Liu Che and Wei Qing hurriedly followed.

At this time, Wei Zifu was still working hard in the field to pick sweet potato seedlings.

Tang Qi shouted: "Sister, stop for a moment, I'll teach you how to pick sweet potatoes!" ”

Wei Zifu straightened up, hammered his waist, and said a little tiredly: "I really need to teach Mr. Tang, it's too difficult to pick red vegetables!" ”

Tang Qi shook his head helplessly, jumped into the ground, took out the simple shovel he carried with him, first loosened the soil for a sweet potato seedling, and then pulled it out vigorously.

A large bunch of plump, enticing, red sweet potatoes were pulled out.

Tang Qi patted the soil off the sweet potato and showed it to the three of them: "Na, this is the sweet potato, also known as sweet potato, sweet potato or sash, the taste is relatively sweet, you can eat it raw, you can also eat it baked, steamed, fried, fried, understand?" ”

"This ...... Can this be eaten? ”

Liu Che was a little skeptical.

Tang Qi didn't say a word, he directly wiped one of the sweet potatoes with his sleeve, and then took a bite, and Hulun swallowed it twice into his stomach.

Liu Che's eyes widened instantly: "This ...... Is this really edible? ”

"Of course you can eat it, you can taste it!"

Tang Qi handed the sweet potato he had bitten into to Liu Che.

Liu Che hesitated for a moment, then took the sweet potato and took a bite.

After chewing twice, Liu Che suddenly said excitedly: "The taste is really sweet, I really didn't expect the fruit growing underground to have such a taste, son, you can taste it too!" ”

Liu Che said and handed the sweet potato to Wei Zifu again.

Wei Zifu is a woman in the end.

She didn't take it for the first time, but first used the silk scarf she carried with her to wipe the sweet potato up and down again, and the wipe was cleaner than washing.

Then, Wei Zifu tasted a bite of sweet potatoes.

"Well, it does taste good, like fruit!"

Wei Zifu also exclaimed.

At this time, Tang Qi said: "This thing is much better than fruit, there are more ways to eat, and it can also be used as food!" ”

Liu Che instantly lifted his spirits.

"Mr. Tang, can this thing really be used as food?"

Liu Che asked Tang Qi with great interest.

As the emperor of the Han Dynasty, he broke his heart in order to make the people have enough to eat.

Tang Qi raised his eyebrows and said, "Of course, this can be used as food, it's very full!" ”

"It's really worthy of Xiandao, there are new food crops, it's really ...... What a surprise to me! ”

Liu Che shook his head and praised loudly.

Tang Qi was speechless: "As for it? It's just a sweet potato, and there are many crops that are suitable for food, such as potatoes, which are the most suitable crops for food! ”
