The Journey of Immortality of the Peerless Medical Concubine

"Well, I'll leave this child to you to take care of. Don't let her suffer any injustice."

"My son obeys the order!"

"Father, why did you come to my house today? Is there something important?"

After bowing to Tang Zhentian, Tang Tianyu slowly asked.

Logically speaking, shouldn't Tang Zhentian be in the imperial study dealing with memorials at this time? Why did he come to Prince Wu's mansion for no reason?

Could it be that he came to see his elder brother? But his elder brother hadn't woken up yet.

"Nothing, I'm leaving the palace for a private visit today, and I'll come and sit with you."

"Oh, Father please!"

Hearing this, Tang Tianyu was stunned at first, then he quickly stepped aside and made a gesture of invitation.

In fact, Tang Zhentian had originally planned to go directly to find Wen Liuli, but he had just met Tang Zhiqian, and his thoughts were a little confused for a moment, so he decided to put it aside for the time being.

Tang Tianyu seemed to have realized something. He said nothing, but asked the servants to make two cups of tea.

"The tea in your house is still delicious. After drinking it, I actually feel a little warmer."

"Haha, if your Majesty likes it, I will have someone prepare some for you so you can take it back and enjoy it slowly."

"Have a heart."

Nodding, Tang Zhentian was full of praise for the fried tea. Not only was it delicious, it also seemed to warm the body better than boiled tea.

In addition, he also discovered a characteristic. The tea often does not taste the best when it is first brewed. Perhaps it is because the taste is a bit strong, or there is some bitterness in the middle. Only when it is brewed for the second time can the fried tea bring out the richest aroma.

"Why don't you see Ali girl?"

Putting down the teacup, Tang Zhentian felt that his mind had calmed down a little, and he looked at Tang Tianyu and asked.

"Replying to Father, Madam went out today, and after she came back, she locked herself in the Liuli Garden to study the greenhouse."

"A greenhouse?"

Another new term. Tang Zhentian raised his eyebrows after hearing it. Could this greenhouse be related to the group of servants holding farm tools they saw before?

"Well, greenhouses are a technology that allows plants to grow out of season, which means that vegetables can be grown in winter."

"This is happening!"

Hearing this, Tang Zhentian was completely upset. You know, green vegetables are a rare commodity in winter. Even the royal family can only eat some green vegetables sent from the south. Due to the long journey, the quality of the green vegetables sent is often not very good.

But despite this, Tang Zhentian still regards them as treasures. After all, rare things are valuable. If it were any other season, Tang Zhentian would not even look at those things twice.

But now Tang Tianyu said that he could grow vegetables in winter, which made Tang Zhentian a little uneasy.

If this is true, then this technology must be in the hands of the royal family at all costs. It will benefit the world.

"Haha, it's true that I have built a greenhouse before. But the conditions here are limited, and I don't know if Ah Li can succeed. If she can, the vegetables she grows will be sent to the palace for my father to enjoy."

"No, no, no, vegetables are a piece of cake! If you can really grow them, you must teach this method to the Ministry of Agriculture. This will be a blessing to the whole world."

"Yes!"

Hearing this, Tang Tianyu was stunned at first, then he bowed and the next moment he understood Tang Zhentian's intention. He thought that Wen Liuli would not be stingy with this kind of technology, so he agreed first.

"Old White!"

At this moment, Wen Liuli's voice suddenly came into the front hall. Both of them turned their heads when they heard it, and then saw Wen Liuli running in with mud all over his face.

"Hey! His Majesty is here too! Ahri greets His Majesty."

When Wen Liuli saw Tang Zhentian, he was visibly stunned, then quickly bowed and said.

"No gift."

"I heard that you were researching some kind of greenhouse. Have you made any progress?"

"Um...you already know all this."

Hearing what Tang Zhentian said, Wen Liuli smiled and then hurriedly explained.

"Your Majesty, I don't know if it will work, but I have just planted some seeds in the yard. If you want to know the results, it may take a few days."

"Oh? Take me to see it!"

Hearing this, Tang Zhentian immediately became interested and quickly stood up. He didn't expect that Wen Liuli had figured it out so quickly, which surprised Tang Zhentian.

Naturally, he was also very curious about what kind of technology could make plants grow out of season.

After Tang Zhentian finished speaking, Wen Liuli brought Tang Zhentian and Tang Tianyu to Liuli Garden.

At this time, the original green plants in Liuli Garden had completely withered. After being completely removed by Wen Liuli, only a piece of soft land was left. Above the land, there was an obvious arch made of bamboo strips, and the arch was covered with some insulation materials.

This material was specially found by Wen Liuli. It is almost translucent and can maintain the temperature in the shed while absorbing photosynthesis.

“Is this what you call a greenhouse?”

Seeing the arch in front of him, Tang Zhentian couldn't help but frown. It didn't look like a big deal.

"Your Majesty, the full name of this greenhouse is a greenhouse. In fact, the reason why plants grow in different seasons is mainly due to climate reasons. If the weather is too cold or too hot, it will not be conducive to plant growth. The function of this greenhouse is to isolate the internal and external temperatures."

"No matter what happens outside the greenhouse, the temperature inside remains the same. Of course, just keeping warm is not enough. Plants also need sunlight to grow. This is called photosynthesis. I don't know much about it, but anyway, as long as they are exposed to the sun and kept warm, plants can grow in any season!"

"I see!"

Hearing this, Tang Zhentian immediately understood. Although Wen Liuli said she didn't quite understand, Tang Zhentian still understood it. The general meaning was that plant growth requires three conditions: one is the right temperature, the second is moisturizing to absorb water, and the third is sunlight.

With these conditions, it can grow no matter what the season or the environment.

The specific principle of this greenhouse is not something that a poor student like Wen Liuli can understand. She is just copying. When she was on Blue Star, Wen Liuli had seen many greenhouses. Even in rural areas, almost every household has some simple greenhouses for seed germination.

Growing up in the countryside, she naturally knew some relevant knowledge, but not much.

“How long does it take for it to germinate?”

This is what Tang Zhentian is really considering. If the germination period is too long, it will definitely be too late for disaster relief.

"Should be... three or four days?"

"Ok?"

Hearing this, Tang Zhentian raised his eyebrows. Is this thing so fast?

In fact, what Wen Liuli said was a bit conservative. In the greenhouse, the speed of plant germination and growth is much faster than in the natural environment. Some seeds planted today may sprout tomorrow. Usually it takes two to three days. After all, the growth of vegetables is different from that of trees. The growth cycle of vegetables is very short, so germination is naturally fast.

"Okay! If it sprouts, Yu'er, send someone to the palace to inform me. I want to come and see it in person!"

"My son obeys the order!"

Hearing this, Tang Tianyu smiled slightly, then bowed to Tang Zhentian.

“Why didn’t you build a greenhouse on that piece of land?”

As he was talking, Tang Zhentian pointed to an empty space on the side. The land there had obviously just been turned over, and it was unknown whether there were any seeds in it. However, Wen Liuli did not cover the greenhouse, which made Tang Zhentian a little curious.

"What's grown there is spinach, which can grow in winter, so there's no need for a greenhouse."

Looking in the direction Tang Zhentian pointed, Wen Liuli hurriedly explained.

In fact, she didn't expect Tang Zhentian to be interested in this thing. The reason why she could say in front of the shopkeeper that she would take care of the vegetables was not entirely because of the greenhouse.

Some things can grow in winter, but the locals don’t know about it. They eat pickles every winter, and I don’t know how these natives survive.

Take spinach for example, it is a standard item in winter. In the cold winter, who wouldn’t have a few spinach leaves in their fields?

"Oh? Is this happening?"

Hearing this, Tang Zhentian's eyelids jumped. Regardless of whether the greenhouse technology was really as Wen Liuli said, the spinach alone was amazing.

You know, the most lacking thing in winter is vegetables, and if spinach can grow in winter, it can solve the urgent problem even without a greenhouse.

"In addition to spinach, there are many more. I remember that celery also grows in winter, as well as Shanghai greens, leeks, rapeseed, winter cabbage, etc."

"is it?"

"If your majesty doesn't believe it, you can ask the people from the Ministry of Agriculture to come and try it out and you will know."

"Okay, Yutai! Go to the Ministry of Agriculture later and tell them what the princess said, and ask them to keep busy for me during the winter!"

"I obey your order..."

Yu Tai had just washed his face, and there was still a burst of white smoke on his face, obviously he was very cold. But he didn't care about the coldness on his face at the moment, and secretly took note of the vegetables Wen Liuli had just mentioned, and decided to go to Sino-Agriculture Department soon.

But what are Shanghai green and winter sorghum? Why have I never heard of them?

Forget it. The queen is a remarkable person. It is normal that I don’t know what she knows. I think the people in the Sinong Department should know it.

"Your Majesty, it's cold outside. Why don't you go inside and rest?"

"Yes, come on! Follow me into the house!"

Hearing Yu Tai's words, Tang Zhentian also shrank his neck, then nodded, and walked into the house with Tang Tianyu and the others.

As for Wen Liuli, she went to wash her face. She had a lot of mud on her body from farming just now. She also went to change her clothes.

Originally, these tasks could be handed over to servants, but Wen Liuli still did it herself. After all, she was not sure that she could grow the fruits at the moment. If she ordered others to do it, some mistakes would inevitably occur.

However, Tang Tianyu, who was following behind Tang Zhentian, couldn't help but frown.
