Nothing happened that night.
The next day.
The sky was just beginning to brighten.
Old Cheng walked out of the room.
This was the most comfortable night he had slept in the past month.
Ever since he came to the north of the desert.
He was on tenterhooks all day, bringing the soldiers beside him.
Eat in the wind and sleep in the open.
Not to mention not resting well, even eating had become a luxury.
Until today.
He had just had a good sleep.
He ate his fill.
Walking in the courtyard, he breathed in the fresh air of the Northern Borderline.
He couldn't help but feel relaxed and happy.
However, he also decided to leave Youzhou City today.
It was better to return to Chang 'an as soon as possible and report the news to Li Shimin.
It was also good for Li Shi Min to report to Li Yuan.
He wanted them to be prepared…
Now, the barbarians seemed to have made no move.
However, Old Cheng had a vague feeling that Jie Li was brewing a bigger conspiracy.
At this moment.
Suddenly.
He saw Lin Wu rushing over with two servants.
"Hmm?"
Old Cheng knew them. He knew that Lin Wu was a lieutenant in the army.
He was also a servant of the general's residence.
"Brat, what are you guys doing so early in the morning?”Cheng Yaojin asked in confusion.
Hearing this.
Lin Wu hurriedly stopped and bowed.
"Oh, so it's Duke Su!"
" Young Master is planting something in the back. He wants us to go over and help…"
"Who is it? Are you talking about Lin Qiu?" Old Cheng was slightly startled.
He did not expect this either.
A dignified young general actually knew how to farm?
This more or less piqued his curiosity.
"Yes!" Lin Wu nodded and replied.”
"Heh, interesting. Let's go, let's go. I'll follow along and see what that kid is up to!”
Hence, he decided to do it.
Cheng Yaojin followed Lin Wu and a few servants.
Together, they hurried towards the backyard.
The General's manor was very large, with a total of thirteen courtyards.
Other than the five courtyards in front, the rest were all abandoned.
Most of them were used to pile up some junk.
After all, there were not many people in the residence, and there were not many servants.
Usually, there were not many people who came to the northern border to be guests.
Hence, the two of them were in a daze.
The number of customers was also limited.
They had only prepared a few guest rooms and the courtyard where the servants lived.
As for the rest, he didn't need them.
At this moment.
Lin Qiu was in a courtyard at the back, turning the entire place into a field.
At this moment.
He was burying the sprouted potatoes and sweet potatoes into the soil one by one.
This was the courtyard that Lin Qiu had carefully selected.
The lighting was the best, suitable for the growth of potatoes and sweet potatoes.
At this moment.
Old Cheng and Lin Wu walked over.
"Kid, what are you doing here?”Cheng Yaojin said with a frown.
Hearing this.
Lin Qiu turned around.
"Oh, it's nothing. I just came over to plant some potatoes and sweet potatoes!"”
"I wonder if the soil in the northern border can grow and how much per mu it will produce!”
"Sweet potatoes?"
"Potato?"
"What is this? I've never heard of it!"
Old Cheng was dumbfounded.
It was normal that he had never heard of it.
After all, sweet potatoes and potatoes hadn't been introduced into the Tang Empire yet.
"Oh!"
"This is something I discovered by accident…This thing tastes pretty good, and the production is also quite good!”Lin Qiu said casually.
"The production is still okay?"
Old Cheng was slightly startled and quickly asked,""What is the yield per mu? Do you have 300 catties?"
Hearing this.
Lin Qiu smiled and shook her head.
"Could it be that it's only 200 catties?”Old Cheng frowned.
Although 200 catties was not a lot.
However, at this moment.
It was not bad, but he still did not know.
How were the sweet potatoes and potatoes used? Was the taste really as good as Lin Qiu said?
"Say it high!"
"Too high? Could it be that there are five hundred catties?" Cheng Yaojin was really surprised.
In the end.
Lin Qiu shook her head with a smile.”
"You still want to guess? Kid, don't keep me in suspense. Just tell me, how much can you produce?”
"Could it be that it can reach more than 500 kilograms?”Old Cheng was getting impatient.
"Yes, Duke Su, you guessed it right this time!”
"These sweet potatoes and potatoes can be eaten as vegetables or as staple food. They can be stored well, and they are not picky about planting. As for the yield…based on the soil in the northern border!”
"It's not a problem to produce about 2,000 catties per mu!”
"What?"
"Two thousand catties per mu?"
Old Cheng's eyes almost popped out when he heard this.
Just 500 catties.
It was enough to shock him.
In the end.
This Lin Qiu was asking for 2000 catties per mu?
If he could really achieve this production.
It was naturally not difficult to solve the crisis of the Great Tang's people.
In fact…
He handed the sweet potato to Li Shi Min, who was still the King of Qin.
If he were to offer it to Li Yuan, perhaps…
"Brat!"
"Are you serious? Can it really produce two thousand catties per mu?"
"No, don't brag to me, even if it's only a thousand pounds!”Cheng Yaojin quickly said.
Lin Qiu nodded.
"A conservative estimate is about two thousand jin!”
"If you take good care of it and get enough sunlight!”
"Maybe the production will increase a little!”
Hearing this.
Old Cheng went crazy.
The yield per mu was two thousand catties, or perhaps even more.
How could he not be shocked?
If this thing was brought back to Chang 'an and given to Li Shimin, the King of Qin…
Just as he was about to say this.
Suddenly.
A person rushed in from outside, looking extremely flustered.
"Duke Su!"
"Young Master, big…something bad has happened!”
"There are, there are barbarians. Their troops are approaching our city!”
"General Qin sent me here to invite you to the city wall…"
"What?"
When he heard this.
Whether it was Lin Qiu, Cheng Yaojin, or Lin Wu.
Their expressions changed drastically.
They looked at each other.
He no longer had the leisure to discuss sweet potatoes and potatoes.
They all turned around and ran towards the front yard.
Not long after.
When they arrived at the city wall on their warhorses.
Qin Baichuan and the soldiers in the city were all here.
He looked out of the city wall.
Instantly.
Even Lin Qiu was shocked.
On the other side of the moat.
It was a vast area filled with barbarian armies.
Additionally, they were all approaching Youzhou City with killing intent…
