I became emperor in the Tang Dynasty by relying on the palace fighting system

Qingluan looked over quietly, and the faces she saw, regardless of gender, age or status, were all filled with ecstasy.

Insects, how many people in ancient and modern times, both in China and abroad, hate them to the core.

Now that they have pyrethrum, they can save some energy when working and no longer have to work so hard to catch insects.

The people around were all delighted, and Li Zhao also laughed particularly happily when he landed.

"This is a good thing! Thank you, Nuyi!"

Nvyi's smile was as bright as a spring flower: "No need, if His Majesty Xuanzun wants to thank someone, then thank His Majesty Taiyi Jiuku Tianzun."

Li Zhao smiled widely: "Taiyi Mother Goddess is still the best. I know that she will definitely help me accumulate 100,000 good deeds!"

Nuyi chuckled: "It's good that Xuanzun knows, but His Majesty Taiyi also has something for me to bring to Xuanzun."

The smile on Li Zhao's face never faded: "What? Tell me about it."

Nüyi said: "Your Majesty Taiyi, please make sure to work hard for the welfare of the people and stop acting recklessly."

Li Zhao pursed his lips, pretending to be reluctant but had to submit: "I know! Am I not doing it now?"

Nvyi's smile deepened, and she walked in front of Li Zhi and Wu Meiniang again: "Emperor and Empress of the World."

Li Zhi and Wu Meiniang looked solemn and bowed to her: "Your Highness, Nuyi, thank you very much for your grace, Taiyi Jiuku Tianzun, and for giving me the magic herb."

Nüyi said, "You don't have to thank me. But I have something to tell you."

Wu Meiniang hurriedly said, "Your Highness, the Goddess, please speak."

Nvyi smiled and said, "Pyrethrum can kill most pests, but there are some insects that cannot be killed, such as locusts. You must be careful and not be careless."

Li Zhi and Wu Meiniang nodded seriously: "Yes, I understand."

Nüyi said again: "Come again, the gods in heaven showed themselves to help Yudou Xuanzun overcome the calamity and not to seek the incense of the mortal world, but they did not help you in vain."

Li Zhi understood immediately, and he bowed down and said: "In the name of the emperor, I will make the merits of the gods spread throughout the world, and future generations will continue to worship them."

He was so wise that Nuyi nodded with a smile.

She turned back and said to Li Zhao, "Xuanzun, your three mother goddesses, Xiling Jinmu Emperor, Taiyi Jiuku Tianzun, and Wahuang Zhisheng Da Tianzun, have all sent people to the mortal world to find your sisters and come to help you."

"Xuan Zun, just be at ease."

Li Zhao raised his eyebrows: "Nüqing... No, Taiwei Mother Goddess, she didn't say anything?"

Nüyi smiled calmly, her tone meaningful: "Your ancestor god, the Great Heavenly Venerable Taiyuan Holy Mother, has come forward."

Li Zhao was slightly startled, then slowly raised the corners of his mouth.

Everyone instantly saw that Yudou Xuanzun put his hands on his waist and revealed an extremely arrogant smile.

Sure enough, favored children are always fearless.

Everyone was muttering in their hearts that Xuan Zun had only been at peace for two days and they were afraid that her arrogance would rise again.

Qingluan: Humph! What do you know! Yudou Xuanzun is the darling of the heavenly court.

What’s wrong with being a little arrogant?

Some second-generation rich people also have a deep understanding of this.

Back then, they had the support of their grandparents, so they were really naughty kids.

Yudou Xuanzun is probably the worst of the worst.

The female barbarian left the basket and said, "In addition to white pyrethrum, there are also red pyrethrum and tobacco seeds. They can also be used to make insecticides."

"I am leaving now. Take care, Xuanzun."

Qingluan retracted her clone, and Nuyi disappeared in a puff of green smoke.

Only a field of colorful flowers remained as evidence that Nuyi had once descended to the mortal world.

The people happily began to pick and dig flowers: "These are flowers left by the gods, they will definitely sell for a good price!"

Some scholars and ladies looked reserved, but their sleeves were stuffed full of flowers.

Some scholars and ladies had already started looking for plants left behind by the Nuyi.

Li Zhao and others did not hinder them, but watched their actions with a smile.

The learning banquet ended successfully. Li Zhi and Wu Meiniang issued another decree to build Taiyi Palaces in various places in the two capitals to worship Taiyi Jiuku Tianzun and Nuyi Goddess.

There were not many pyrethrum and tobacco seeds, so Li Zhao planted most of them in his own estate, and gave some to Li Zhi and Wu Meiniang.

Wu Meiniang and Li Zhi issued an edict to hand over the seeds to the ministers of the Sijia Temple for planting.

Wu Meiniang said solemnly, "Si Jiaqing, pyrethrum and tobacco are of great importance. You must carefully study the planting booklet that the goddess Nuyi left in the bamboo basket, and breed them as soon as possible and promote them to all counties in the Tang Dynasty."

Si Jiaqing's face was full of joy and glow: "I obey your command! Your Majesty, Your Highness, please rest assured!"

Li Zhao's disciples have been trained almost completely, so she uses the [Live Travel Module] to enter the virtual world and tells them that the time has come.

In June, when the red and white pyrethrum flowers were in full bloom, Yudou Xuanzun issued an order to collect new agricultural tools, and each one was rewarded with 100 strings of cash.

Huang Jiaoniang took the lead in presenting the flying shuttle loom, and Li Zhao took her and several children to meet Li Zhi in person.

Li Zhao pulled Huang Jiaoniang over, full of hints.

"Le Xian is now an official at Tongwen Temple."

Li Zhi: “…………”

Before he could have a headache, Wu Meiniang smiled and said, "The flying shuttle loom is indeed a good thing. Your Majesty, why not confer a title on Huang Niang first?"

Li Zhi's heart moved.

Qingluan coughed and said, "Lord of the Weaver Girl, also known as His Royal Highness the Grandson of Heaven, is the daughter of the Goddess of the Nine Heavens and the grandson of the Emperor of the Golden Mother of the West Spirit. She is also the little master of this god."

The implication is that the title cannot be given to a young person.

Li Zhi smiled and said, "Then confer the title of Kaiguo County Marquis on Huang Niangzi, Jinzi Guanglu Dafu, and let her enjoy the same honors as the other star gods, but she doesn't need to bow when she sees the emperor."

Li Zhao was happy. She smiled and said, "I have asked them to make something. Emperor, Empress, gather all the ministers and go take a look together?"

Li Zhi and Wu Meiniang readily agreed and took the prime ministers to the polo field in the imperial palace, where the three things had already been placed.

The first invention, the flying shuttle loom.

The second invention was the spray vehicle and sprayer modified by Li Zhao.

The third invention was the foot-operated thresher and wheat thresher.

Needless to say, the flying shuttle loom was useful. Li Zhao specially asked someone to demonstrate the use of the spray truck and sprayer.

Li Zhao took the opportunity to open the live broadcast room and let the audience fans listen to the female official of Taiwei Changzhu Mansion introduce these three types of inventions.

The barrage was full of surprise.

[Shi Qian Gai]: I didn’t expect that the host’s transformation was actually successful!

The spray truck is a small one-wheeled cart with a bracket and a handle. A long pole stands high at the front and is tied to a thin bamboo tube in a cross shape.

A water tank is fixed above the wheel. The water tank has gear blades and is connected to the wheel with a gear chain.

When the water tank is filled with water, the spray truck is pushed and started running. The gear blades stir the liquid in the tank, which is transferred to the thin bamboo tube in front through a long-necked funnel-shaped object and sprayed out from the small hole to form water mist.

Li Zhi, Wu Meiniang, and the prime ministers surrounded the spray truck and looked at it again and again.

As I watched, I marveled at it.

"Wow, this thing is very unique!"

"This is the first time I've seen a small car like this in my life."

Li Chao said: "This car can be filled with human and animal urine, medicine, and clean water for spraying, and nothing else can be done."

Li Zhaoze told fans: "The specific production principle of the spray car is Bernoulli's principle and gear transmission device."

"Please refer to your high school physics textbook for details."

I understand the barrage.

【N70-珺】：?! Is this knowledge in the high school physics textbook?

[Destiny Nüwa]: I suspect we studied physics from the same book.

[Shao Yue]: How does the anchor use these principles to transform things?

[Punish the evil and praise the castrated]: Same question, it feels like my brain has the ability but my hands are useless.

Li Zhao smiled and said modestly: "It's not difficult actually. It's just that it's not very good due to the times and the raw materials."

"The spray truck is suitable for use on plains. The sprayer is a common old-fashioned shoulder-mounted rocker sprayer. It is made by splitting a tree stump in half, hollowing it out and thinning it."

“It’s not very convenient without the rubber tube, but at least it can be used and can be promoted to the south.”

Li Zhaohe's fans sighed: "The road to infrastructure construction is long and arduous."

The barrage comforted Li Zhao.

[How can such a gift be given]: Don't push yourself too hard, you've done a great job!

[Lu from Hot Spring Villa]: If we were in the heroine's situation, I'm afraid we would be nothing but waste.

[Dan Jin]: Is the heroine’s next plan to promote these three types of inventions nationwide?

Unexpectedly, Li Zhao denied it: "No."
