If you traveled back to ancient times, while others ate Guanyin clay, you would actually have giant

"What? Who is more skilled than the imperial physician? Has someone found a cure?"

Upon hearing that their daughter's condition had improved, the parents quickly pressed for more information.

"It is Zhou Wu, the commander of the Qingyang Army."

The Qingyang Army must be military personnel, but even Gu Xinyuan, a high-ranking military officer, couldn't figure out who Zhou Wu of the Qingyang Army was after thinking for a long time.

"Does he have a way to cure you?"

He said the disease was incurable.

"What."

"Father and Mother, don't worry. Although he said there was no cure, he did have a way to prevent it. Since he saw me, I haven't had a relapse."

"That's good, that's good. Amitabha, may the Bodhisattva protect us."

Mother Gu repeatedly bowed, expressing her gratitude to the Bodhisattva for protecting her.

"Daughter, is there something you need to do when you come back this time?"

Gu Xinyuan was overjoyed to learn that his daughter's condition was under control. However, having lived most of his life, he could naturally guess his daughter's little thoughts.

"As expected, nothing can be hidden from Father. This time, when the Crown Prince and I went to Qingyang County, we happened to be there during the autumn harvest in Niujia Town. Two new crops were planted there. The Crown Prince and I witnessed the entire harvest firsthand. Father and Mother, can you guess how much these two crops yield per mu?"

"Haha, if you ask that, then it must be highly productive."

How could a father not understand his own daughter?

"San Shi?"

"wrong."

"Four stones?"

"That's not right either."

"Five shi is correct, right? That's really good. It actually yields five shi per mu. Have you brought it back to the Sage so that it can be promoted throughout the country?"

Five shi (a unit of dry measure) was already Gu Xinyuan's limit, and it was also a figure that Dalong's grain yield per mu (a unit of land area) had never reached before.

"No, Father, one yields ten shi per mu, and the other yields twenty shi per mu."

Gu Xinyuan was startled at first, then relaxed his brows and laughed.

"Xue'er, are you joking with your old man? In this world, let alone a yield of 20 shi per mu, there has never been a yield of 10 shi per mu."

“Father, it’s true. The Crown Prince and I saw it with our own eyes. The Crown Prince even brought back the samples. He just arrived today and went to see the Emperor, but the Emperor, like you, didn’t believe it at all. He even scolded the Crown Prince. Now the Crown Prince is disheartened and has locked himself in his study.”

Gu Xinyuan certainly didn't believe that there was any grain in the world that could yield more than ten shi per mu, but he knew his own daughter best.

"Xue'er, are you sure you saw all this grain with your own eyes?"

"Yes. Not only me and the Crown Prince, but all the people in Niujia Town know about it."

“Alright, I will go to Niujia Town immediately. If it is true, I will personally report to His Majesty.”

"Thank you father."

Gu Xinyuan was a decisive person, especially since this matter concerned his daughter and the crown prince, as well as the great cause of the Great Dragon. After having dinner with Gu Xueling, he took a few subordinates and rode south at full speed.

Over three days, Gu Xinyuan changed horses but not his rider, and finally arrived at Niujia Town after a long and arduous journey. When he first saw Niujia Town, he was shocked.

A small border town, surprisingly, has city walls.

"Your Excellency, this town is no ordinary place."

The men who had been with him all along were his brothers who had gone through thick and thin with him over the years, and even they were somewhat confused at this moment.

"What haven't we brothers seen in our lives? This is nothing. We've been through dragon's dens and tiger's lair before."

"Yes, the Duke is right."

"Hahaha."

"Ha ha,"

In Gu Xinyuan's eyes, his group was at the gates of a dragon's den, laughing heartily, how magnificent! But in the eyes of the workers building the city wall, it was a different story.

"Hey, look, a few more country bumpkins have come and are grinning like idiots at the gate."

"These bastards, they never ask for anything, what are they laughing about all day?"

. . . . .

"Boiled corn, sweet boiled corn."

A woman was setting up a small clay stove by the roadside, selling boiled corn.

"Go buy a few."

"promise,"

"Boss lady, have a few ears of corn to try."

"Please wait a moment, sir."

When the proprietress saw a customer coming in, she quickly and efficiently wrapped a few ears of corn in lotus leaves and handed them over.

"Boss lady, how do we eat this?"

"Hehe, the customer must be from out of town. This corn, just peel off the outer skin and eat it directly, it's simple."

"Oh, thank you, ma'am."

The group stood in front of the stall and started eating corn. It has to be said that the sweetness and texture of the corn were quite good.

"I've never seen this kind of corn anywhere else, ma'am."

Gu Xinyuan bought corn not only to try the new grain, but also to try and get information out of the other party.

"Guest, this corn is only available in Niujia Town in the whole of Dalong. It's a high-yield variety that Lord Zhou Wu found. You wouldn't believe it, our family's harvest this year is so plentiful that we can't even store it all. That's why we're setting up a stall on the street now, trying to sell whatever we can."

"High yield? How high can it be?"

Gu Xinyuan asked seemingly casually, but in reality he was extremely nervous.

"Not much, about ten shi per mu."

"really?"

The answer of ten koku was exactly the same as what his daughter had said. He was very pleased that what his daughter said was true, but the production of ten koku broke his long-held understanding.

"Haha, can't believe it? I've seen it these past few days, but there's nothing I can do about it. This is the yield. Our other type of potato has an even higher yield, reaching twenty shi per mu."

After the proprietress finished speaking, her face was full of pride, and she was also waiting to see the shocked expressions on the faces of the out-of-towners in front of her.

Gu Xinyuan spent a day in Niujia Town, concealing his identity. The grain yield information was basically true, and Niujia Town left a deep impression on him. In the end, he decided to find Zhou Wu to confirm.

. . . . .

"Sir, Master Niu wants you to go to the town government office right away. He says someone is looking for you."

Zhou Wu rarely goes to the town government office anymore. After all, his identity is the commander of the Qingyang Army, while Niu Ye is the town mayor. That's what Zhou Wu says to the outside world, but whether he's actually just trying to slack off or not, nobody knows.

"Okay, I'll go right away."

Generally speaking, Master Niu could handle most of the town's affairs, so he rarely needed to contact Zhou Wu. However, this time someone specifically asked for him by name, and through Master Niu, so it must be someone from the government. Therefore, Zhou Wu didn't dare to delay for even a moment.

Upon arriving at the government office, Zhou Wu saw a middle-aged man with an ordinary appearance. However, in addition to his ordinary appearance, he was also very upright. Zhou Wu guessed that the man must have come from a military background.

"My name is Zhou Wu. May I ask how you should address me?"

"Scholar, this is General Gu Xinyuan, the current Duke, and the father of the Crown Princess."

"Greetings, Duke Gu."

This was definitely a high-ranking official, so Zhou Wu quickly bowed.

"No need to be so polite. I'm a straightforward person, so I'll just say it directly: the Crown Prince and Crown Princess came to your place some time ago and witnessed the harvest of corn and potatoes with their own eyes."

"Yes, Duke Gu."

"The yield of corn and potatoes can indeed reach ten shi and twenty shi per mu, respectively."

"Yes."
