After the whole sect traveled to ancient times, I led the rebellion

Master Xu was sitting on a chair. His farming family was in decline, and he didn't know whether his sudden visit would displease the county magistrate.

Footsteps are approaching.

Master Xu's gaze rested on the door frame.

The first person to enter was a child about eight years old.

Following behind the child was a middle-aged man, and Master Xu bowed to the man.

Mu Qing's eyes were filled with joy. She quickly walked to Master Xu's side:

"My name is Mu Qing. I have heard of Master Xu's great name for a long time. Today I finally get to meet him."

Mu Qing spoke first.

Master Xu glanced at Mu Qing, what else did he not understand?

Huang County should be ruled by the child named Mu Qing, but when looking at Mu Shan, Master Xu was full of doubts.

Mu Qing first explained the relationship between her and Mu Shan.

Mu Shan knew his abilities, and the man who came was the eldest son of a farmer's family. Mu Shan had never been interested in farmers, so he found an excuse to solve the case.

There are many trivial cases in Huang County, and there are always new disturbances every day, such as neighbors fighting over soil and fertilizer theft, farmers trampling other farmers' crops...

All kinds of strange events, it’s hard to sort out the mess.

Mu Shan got a headache when he thought about this.

Only Master Xu and his disciple Guangtu were left in the house.

Master Xu was very curious about the vegetables that came from Huangxian, as farmers didn't have so many complicated rules.

Master Xu expressed his doubts about these vegetables when he was in Guangsha City.

Mu Qing understood it clearly.

The agricultural school is also one of the Hundred Schools of Thought. Its disciples are not only engaged in agriculture, but are also well-versed in academic studies.

It is not easy to convince such people with words.

Mu Qing originally wanted to quote classics and use the Four Books and Five Classics to trick Master Xu into joining Huang County.

Unexpectedly, the reason why Master Xu came to Huangxian was to grow vegetables with soil fertilizer.

Mu Qing was already very excited in his heart, but he looked serious on the surface.

"The vegetables in Huang County are different from those in other places. They are fertilized from the beginning, and with the rational use of the soil, they naturally grow tall and strong."

"Tufei?"

When it comes to the level of agricultural development in the Tianchi Dynasty, the highest level is among the farmers. Advanced technology and high-quality seeds are basically concentrated in the farmers.

Farmers have also studied soil and fertilizer, but the soil and fertilizer in Master Xu's hand cannot make vegetables grow as strong as Mu Qing said.

Master Xu felt as if he had been scratched by a cat. He had never had the dignity to begin with.

Like the Mohists, the Nongjia people are all honest and pragmatic.

"Can I take a look at this soil?"

Master Xu said directly.

Mu Qing was waiting for Master Xu to speak. A hint of joy appeared on her brows, and she immediately pulled Master Xu's sleeve.

Mu Qing has a very clear idea of ​​her own position. She is still a child. Regarding the great talent who is about to gather her on horseback, Mu Qing says she does not feel any burden at all.

Master Xu looked at Mu Qing and immediately thought of his own child's childhood appearance, and his eyes softened a little.

The two walked all the way to the Doi Factory.

Now the Toei Factory is the busiest place in Huang County besides the public notice area.

"I think the raw materials of these fertilizers are similar to those made by farmers." Mu Qing pointed to the first place on the production line where processing begins.

Master Xu looked at the cartloads of night incense and nodded.

Mu Qing continued: "However, fertilizer is not just made from night-scented urine, but also from plant ash, animal bones, etc."

"These can all be the raw materials for fertilizer. As for the raw materials for fertilizer, Master Xu must be wondering why these items are used."

Mu Qing paused and repeated the content of the open class on soil fertilizer production that he had taught before.

“Plants need specific nutrients for growth, such as phosphorus, nitrogen and potassium.”

"Phosphorus, I don't know if it is the phosphorus powder needed for alchemy, but what are nitrogen and potassium?"

"Phosphorus is indeed the common phosphorus on the market, while nitrogen and potassium can be understood as an element."

The Tianchi Dynasty is not like the Industrial Revolution era. The current technology tree has not yet touched on chemistry.

The few things that can be linked to chemistry are the small chemical experiments used by alchemists to deceive people and some chemical materials used in alchemy.

Mu Qing began to patiently explain science to Master Xu:

"Matter is composed of elements. A single substance composed of the same element is a simple substance; a single substance composed of different elements is a compound."

Mu Qing did not start by explaining too complicated chemistry topics to Master Xu. He first gave Master Xu a general idea from the first chapter of the chemistry book, "Approaching the World of Chemistry."

"For example, the gas we breathe is composed of various elements, oxygen, hydrogen, helium..."

Master Xu is nearly fifty years old, and his eyes, which have experienced many vicissitudes of life, are completely confused and incomprehensible at this moment.

Guangtu is a young man, and his expression is the same as Master Xu's, but he puts forward his own different views at the right time.

“Air is the spiritual energy of heaven and earth and the source of all things. Isn’t it a single substance?”

The great way is nothingness, the ultimate truth is the abyss. Hands enter the soft void, feet on the floating clouds.

The ancients named air "air" not because they thought air was a non-existent thing, but because they regarded it as the spiritual energy of heaven and earth. However, they did not know the composition of air.

Mu Qing didn't say much. Seeing is believing, so he went straight to the chemistry experiment.

After the Liuli Workshop was built, Mu Qing customized a batch of glass cups and glass rods. They were not as pure as modern beakers, but they were good enough.

The experiment demonstrated by Mu Qing was very simple.

Insert a burning stick of wood into the bottle of air and a tube leading to another glass of water, and then light the stick.

The wood sticks come into contact with oxygen, combustion consumes oxygen, the gas decreases, pressure exists, and the water in the glass flows from the glass into the bottle where the wood sticks are burning.

Mu Qing not only did this small experiment, she also did other simple chemistry experiments.

then……

Successfully saw Master Xu and Guangtu’s eyes becoming brighter and brighter.

"That's it, that's it."

Master Xu was not a stubborn old man. He was committed to developing agricultural ideas and had also worked on soil and fertilizer. After several experiments, Master Xu had a good ability to accept things.

A whole new picture unfolds before your eyes.

Chemistry is a magical subject. Mu Qing thought about it and felt that it was not realistic to cultivate a chemist from a young age.

The arrival of Master Xu gave Mu Qing different ideas about lighting up the technology tree.

Chemistry is not only needed in agronomy, but also in medicine, food, materials, etc., covering all aspects of life.

Master Xu's enthusiasm for chemistry was beyond Mu Qing's imagination.

Before Mu Qing could bring up the principles of the Four Books and Five Classics and talk about the theoretical and practical application of shape in biology, Master Xu decided to join Mu Qing's team.

Master Xu came to Huang County and moved all his family assets here with the intention of settling down, but he would not leave until he had sorted out his doubts.

After receiving Mu Qing's dimensionality reduction attack on his knowledge of chemistry and biology, Master Xu instantly changed his attitude.

What hybrid rice, what recessive traits, dominant traits...

Based on the increase in grain production, Master Xu said that he is not old yet and can continue learning!
