Datang: I was exposed by Princess Changle

"This is a photosynthetically active radiation meter, that is, an instrument that detects the intensity of light, and its function is similar to that of a hygrometer."

"With these instruments for measuring various environmental data, we can artificially create an environment suitable for the growth of tulips in the shed, and change the external environment at various stages of tulip growth, so that tulips grow faster. better!"

...

Chapter 782 What do you think about this matter?

Hearing Lin Xuan's explanation, Du Ruhui and the three of them looked at these magical gadgets, their eyes sparkled suddenly.

magical!

Amazing!

No wonder!

No wonder Lin Xuan said that within half a month, he could cultivate countless kinds of tulip flowers.

Turn this place into a sea of ​​flowers!

It turned out that he had so many magical methods.

It seems that after half a month, they will really be able to see a beautiful sea of ​​flowers here!

Du Ruhui and the three praised in their hearts.

Afterwards, Du Ruhui and Duan Lun were thinking about whether these magical gadgets could be used in other ways.

For example, they quickly thought that hygrometers can be used in metal smelting, papermaking, printing and dyeing, etc., where the humidity of the environment needs to be controlled.

The photosynthetically active radiometer can be widely used in astronomical exploration, crop planting and so on!

These gadgets are simply artifacts!

Lin Xuan looked at Duan Lun and Du Ruhui's eyes and knew what they were planning.

He smiled bitterly and said to the two: "Don't think about using these instruments in other places now, I used all the raw materials to make just a few, which are barely enough for these greenhouses!"

Hearing what Lin Xuan said, Du Ruhui and the two were slightly disappointed.

However, do not despair.

Because, at this moment, Lin Xuan continued to say to them: "Although I don't have any more of these gadgets now, after our advanced precision instrument industry develops, don't worry, how many of these things do you want in the future? That's how many!"

Hearing Lin Xuan's words, the eyes of Du Ruhui and Duan Lun suddenly lit up.

At this moment, they are looking forward to a bright future.

But the warrior guard looked at Lin Xuan in shock.

He found that the more he got in touch with Lin Xuan, the less he knew this amazing son-in-law!

Could it be that there is really nothing in this world that Lin Xuan can't do? !

Afterwards, the samurai nurse thought about it carefully, and he found that until now, there is really nothing that can stop Lin Xuan!

After Lin Xuan finished speaking, he began to place these measuring instruments around.

Afterwards, Lin Xuan divided the entire greenhouse area into four areas.

At the same time, it corresponds to the four levels of spring, summer, autumn and winter.

And, by using various means, the four areas were adjusted to the best environment for the growth of tulip flowers.

Afterwards, Lin Xuan began to take out various tulip seeds and let the farmers plant them.

Three hours later, the entire area in the greenhouse was planted with various tulips by the farmers.

The next day.

The imperial palace, in the Tai Chi Palace.

Morning above.

"See Your Majesty!"

A group of civil and military officials bowed to Li Shimin in unison.

"My dear friends, do you have any important matters to announce?"

Li Shimin asked calmly as usual.

"Report to Your Majesty, I have something to play!"

Tang Jian, Shangshu of the Ministry of Rites, stood up after hearing the words, and said to Li Shimin respectfully.

"Sure! Tang Aiqing, what's the matter?"

Li Shimin asked casually and dignifiedly.

"Your Majesty, Queen Seondeok of Silla sent an envoy to ask for assistance from Tang Dynasty."

"Most of the grain they planted in Silla this year was submerged by seawater a few days ago."

"Therefore, their food supply is very short now, and Queen Seondeok specially sent their envoy Jin Chunqiu to borrow food from Datang."

Tang Jian, Shangshu of the Ministry of Rites, replied reverently.

As soon as this word comes out.

Li Shimin showed a slight look of surprise, and said majestically, "Oh? The food in Silla was flooded?!"

"Where is the Minister of the Household?"

"The minister is here!" Liu Zhenghui, Minister of the Ministry of household affairs, immediately came out of the queue and replied after hearing the words.

"Liu Shangshu, do you still have surplus food in the treasury?"

"If you lend them, how much food can be lent to Silla?"

Li Shimin asked with a serious face.

"Your Majesty, this year our army expedition defeated the two great empires, the Byzantine Empire and the Great Food Empire, and now our railways leading to the Sun Empire and the Charlemagne Empire are also under construction."

"Datang's current territory is also expanding and getting bigger. Suddenly, the population of Datang has surged rapidly. Thanks to the surplus food we left before, our own food supply in Datang is barely enough this year!"

"Besides, the grain seeds we distributed this year have already been sown."

"We don't have enough surplus food to borrow for at least half a year!"
