In the past few days, Mo Shang and a group of Mo family disciples have been wandering around the fields, keeping a close eye on the farmers harvesting the crops, hoping to make some discoveries.

"Your Majesty, we haven't made any progress these past few days. You know, we've been watching like this for so long, but we still haven't found a clue! When will we be able to produce what His Majesty needs?"

The old man looked worried. Whether the Mo family could gain recognition and support depended entirely on this opportunity. If they missed it, they might never have another chance.

Mo Shang pondered for a moment and then said, "What do you think is His Majesty's purpose in having us develop tools?"

The group looked at each other, somewhat puzzled.

"I think it should be to speed up the efficiency of the people and save more time. In the past few days, from my observation, each young and strong person can harvest at most about five mu a day, and that is under the condition of only harvesting and not reaping. For those with more land, the harvesting alone will take seven or eight days, or even longer."

"Oh!!!" The old man's eyes lit up. "Does the Grand Master mean to create a tool to speed up the harvest? To reduce harvesting time?"

Mo Shang nodded and said with a smile, "This way, people can save more time to cultivate wasteland or do other work and increase their income. Isn't this a thing that benefits the country and the people?"

"Yes, yes, yes!!! Or we can also start with the threshing process!"

"Yes, yes!! And the plowshares too. Although the plowshares we made according to His Majesty's blueprints are much better, I think there are still many possibilities for improvement. If we can successfully improve them, it will be a huge breakthrough!"

As if inspired, everyone had various ideas and began to discuss them one after another, with everyone extremely excited.

Ordinary farm tools posed no difficulty for these Mohist scholars who were skilled in mechanical devices; the challenge lay in having no direction. Now that they had a direction, they were confident that they could create what they wanted in a short time.

Mo Shang laughed happily at this moment, "Alright, then let's hurry back, work on the research and development, and produce something as soon as possible to present as a gift to the Emperor!"

"promise!"

Soon the Mo family members returned to the Research and Manufacturing Department, and gathered in twos and threes to begin drawing and studying the details.

On the other side, Cao Song and his group returned to the field, accompanied by several doctors from the medical school.

Whether it's medicine or agriculture, as long as it leaves a mark in history books, it doesn't matter what it is. Faced with such a great temptation, they naturally spared no effort.

Cao Song inquired in detail about the old farmer's farming process, which was no different from that of others, whether it was tilling the land, sowing seeds, or irrigating and weeding.

This puzzled Cao Song, who felt he must have overlooked something.

When Zhang Zhongjing arrived at the field, he noticed something different. He squatted down and noticed that the color of the soil here was slightly different from the other soil, as it was a bit darker.

Zhang Zhongjing picked up a clod of earth and approached the old farmer. "Old man, did you put something in the field?"

"yes!"

The old farmer smiled and then said, "I keep two pigs in my pen. They eat, drink, and relieve themselves in the pen all day long. They're smelly and filthy."

I would often cover the pit with soil and then lay down dry grass. Over the course of a year, the pit grew higher and higher. Fearing that they would escape, I would take out their droppings and pile them in the backyard, then cover them with soil again.

Unexpectedly, the vegetation around the excrement was much stronger than in other areas, so I took some and scattered it on the ground, and it did indeed grow better than in previous years.

Zhang Zhongjing seemed to have thought of something. Why were the medicinal herbs from deep mountains and forests better than those from other places? Could it be that the animal excrement, carcasses, withered leaves, and dust neutralized each other, increasing the fertility of the soil?

Cao Song and several agricultural officials also began to ponder. Manure was not unusual, but it was not as good as the old farmer had described.

"Sir, could you please take us to your backyard for a look?"

Cao Song quickly asked, seemingly thinking it must be related to the old man's method of handling the situation.

"Oh! Alright! Please follow me!"

The old farmer, seeing the group of people in official robes staring at him with gleaming eyes, quickly nodded and led them home.

Soon the group arrived at the old farmer's backyard, where a manure pile as tall as a person appeared before them. However, although the manure pile still emitted a foul odor, it was not as pungent.

Zhang Zhongjing and Cao Song hurriedly walked to the manure pile to take a look. The old farmer was dumbfounded. These people, instead of studying crops, have switched to studying manure.

"Zhongjing, why do you think this is?"

Cao Song couldn't figure it out, so he looked at Zhang Zhongjing beside him.

Looking at the pile of manure mixed with soil, Zhang Zhongjing pondered for a moment and said, "If I'm not mistaken, it should be a mixture of loess and dry grass, which neutralizes the manure so that the plants can accept and absorb nutrients that are useful to them. Just like brewing medicine, you always need some mild ingredients to balance the medicinal properties."

"That makes sense!"

Cao Song nodded in agreement.

"This is a major discovery! We must report it to His Majesty immediately!"

"right!"

"Old man, you've done a great service! Get ready for your reward!"

Cao Song chuckled and said something to the old farmer, then waved his hand, and the large group of people left the place and headed back to the palace.

The old farmer was left standing there, bewildered.

"Organic fertilizer...?"

After listening to everyone's guesses and opinions, Liu Hong was slightly taken aback, then looked at the crowd in front of him with shining eyes.
