Among the officials who stayed, they were all of the same mind as Li Shimin, even if it was Wei Zheng, who was at odds with Li Shimin, they were actually on the same front as Lao Li.

In terms of personality charm, Li Shimin is not the first in 5,000 years of history, but at least it can be said to be the top five stable.

"Dare to ask Your Majesty, what is technology?" Wei Zheng was the first to ask questions.

Li Shimin naturally replied according to the script, seeing that the courtiers did not fully understand the importance of technology, Li Qing showed them two movies with holographic projection.

This time, it was the decisive battle for Midway, and the "Liberation" trilogy filmed by Big Brother.

Several military generals, Qin Qiong, Wei Chigong, Cheng Zhijie, and Hou Junji, stood up involuntarily from the first time they saw the plane.

Think about it, which general can resist the temptation of planes, big ships, and huge guns?

"If there is such an artifact, why should Pharmacist Li raid Yin Mountain?" Wei Chigong patted Fa Fu's stomach, "With just one partial division, you can pacify the Turks!" ”

He was referring to the torrent of tanks rushing in Kursk.

"What does His Royal Highness King Qin mean that if the development is carried out according to the guidelines you gave, in the near future, Datang can also have such an artifact?"

It was worthy of the first merit of Lingyan Pavilion, and the eldest grandson Wuji immediately understood the true meaning of Li Qing showing them the movie.

In addition to being excited, he even pulled off one of his beards and gasped in pain.

"The development of productive forces has never been achieved overnight," Li Qingtan regretted, "but at least it is certain that if Datang goes all out to develop science and technology with my help, it may be able to create these things in a few decades." ”

He wasn't sure, so he drew the cake first.

"The minister thinks it's feasible!" Fang Xuanling arched his hand.

Wei Zheng reached out and took out the potato chips in Cheng Biting Jin's arms, but felt empty. He was not embarrassed, but asked: "With all due respect, His Royal Highness King Qin, can your so-called technology have products related to people's livelihood?" ”

"Absolutely."

Speaking too palely, Li Qing waved his hand, and the hologram began to play.

"This is a medium-sized combine harvester," Li Qing pointed to the harvester working in the field in the picture, "You should also know what it is for when you see the picture, it can harvest about 300 to 500 acres of land a day." ”

"This is a large mechanized cultivator," Li Qing pointed to the giant cultivator in the picture and introduced: "This thing can plough nearly 200 acres of farmland in half an hour, and there are also small and medium-sized ones, and the amount of work is different according to different models." ”

Wei Zheng's eyes lit up as he looked at the roaring machinery in the picture, and he wanted to rush inside and grab one.

It's a pity that he can only watch and be anxious.

"Well, this is an indica-type hybrid rice, with a yield of more than 1,000 catties per mu." Li Qing continued to introduce to the Tang Dynasty, "There are also potatoes and sweet potatoes, which are all high-yield crops with a yield of four or five thousand catties per mu, which can be eaten as vegetables or as food...... These need to be cultivated by the development of science and technology. ”

"Rice...... Sweet potato...... Potato! Li Shimin's eyes were bloodshot as he looked at the mountains of crops in the picture, and his eyes were extremely red.

"Sweet potatoes and potatoes, here." Li Qing transformed the picture into a world map as he spoke, "We set off from here by boat and arrived here......"

With his words, a striking light emerged from the location of South America.

"If a steam ironclad ship is developed, it will take about half a year or even less to make a round trip." Li Qing said.

After saying that, he looked up and saw that the atmosphere was a little wrong.

Everyone stared at the origin of the piece of potato and sweet potato that Li Qing had marked, panting, and looking at people who were choosing to devour.

"The yield per mu is 5,000 catties...... The yield per mu is 5,000 catties......" Fang Xuanling trembled and muttered, his mind was now completely occupied by high-yield crops.

"Who dares to obstruct the development of science and technology! I, Wei Zheng, and him will never die! Wei Zheng stared at the location of South America with tears in his eyes, eager to fly over now and bring over the high-yielding crops of potatoes and sweet potatoes.

"Minister, please order!" Several generals shouted and said: "Please Your Majesty wait for me a few sea ships, if you don't find these crops for my Datang, I will not be human!" ”

Li Qing sighed secretly, this is the Zhenguan court, the court that has not been polluted by the qi of collusion......

"A few generals don't have to be anxious," Li Qing immediately persuaded them, "According to the existing shipbuilding technology, we can't cope with the wind and waves on the sea at all, and we must wait until the shipbuilding technology is discovered and matured."

"So what to do!" Niu Jinda had tears in his eyes, "Every quarter of an hour in the morning, maybe one person will not starve to death because of this......"

"That can't be a joke with the lives of soldiers, General Niu." Li Qing sighed, "What if you go to sea now?" In the vast sea, with the current navigation technology, you can only rely on the ocean current to float over, and you don't want to go back and forth in three or five years? ”

"In this time, the steam ironclad can be built!" Li Qing hated the iron and said with iron, "At that time, not only will the sailing speed be greatly improved, but even the safety will be guaranteed, not much stronger than the current sampan?" ”

"Is what His Royal Highness King Qin said true?" Niu Jinda Huo Ran raised his head, "Is it really only three or five years to be able to build an ironclad ship?" ”

"Of course, as long as no one stands in the way of technological development!" Li Qing said firmly.

Niu Jinda took a deep breath and focused his head, he didn't say anything, but it could be seen from his eyes that those who dared to obstruct the development of science and technology were doomed.

"In addition, the development of science and technology is not only these, such as airplanes......" Li Qing changed the animation again, this time replaced with an airplane for spreading pesticides, "It can be used to spread pesticides and eliminate pests." ”

"This belongs to the category of chemistry and biology, and when it comes to biology, you can also completely exterminate the locust plague by studying the habits of biological restraint!"

Li Qing turned his finger, and a group of beautiful birds with pink bellies appeared on the screen.

"This is a pink starling, like to eat locusts, scientific studies have shown that locusts produce toxins in the body when they are plagued, and this pink starling is immune to this toxin, don't look at their small size, but they can prey on about 200 locusts a day."

The screen jumps to the scene of a pink starling feeding its young birds with locusts in its mouth.

"This ...... Is there such a sacred bird in the world? Li Shimin looked at the birds in the picture with bright eyes, he already likes birds, how can he not like pink starlings that like to eat locusts?

The locust plague in ancient times can be described as one of the most serious natural disasters, starting from the records of the Qin and Han dynasties, the locust plague averaged once every 8.8 years, the Song and Song dynasties averaged once every 3.5 years, the Yuan Dynasty once every 1.6 years, and the Ming and Qing dynasties once every 2.8 years......

Now it is possible to restrain the locust plague through this inconspicuous bird, without the need for large-scale manpower to kill, and for a while, everyone, including Li Shimin, became short of breath again.

"There is not a lack of beauty in the world, but a lack of eyes to find it." Li Qing pointed to his eyes.
