Just when the group walked into the Lu Mansion and walked through the alley to the backyard, Lu Tongren and Xiao Shi also followed here.

Outside just now, He De had already found an opportunity to introduce the identities of these people to them, and all of them were big people who couldn't be provoked.

Except for His Majesty Li Er, who has the highest status, everyone else is a national prince, without exception.

As parents, they were really worried that Lu Heng would say the wrong thing and act recklessly before such a character.

At that time, maybe their family will really be raided!

"Heng'er, why don't you go in with you?"

Lu Tongren pulled his son aside and said in a low voice:

"Although my father and mother also know that your knowledge and ability may be greater than the two of us now. But when it comes to dealing with people, we have eaten more salt than you have ever eaten! ”

"There are so many dignitaries and dignitaries, and even His Majesty is here...... If you don't say anything right, if you offend anyone, I'm afraid your life will be lost! ”

Xiao Shi didn't speak, but nodded approvingly beside him.

They both know their son's emotional intelligence.

Lu Heng shook his head very firmly:

"It's useless for you to follow me in. You don't know anything about the yield and function of potatoes and sweet potatoes, and when Your Majesty asks, can you help answer? ”

"Besides, with Uncle Cheng beside them, if I say anything wrong, the field should be able to come back."

"Don't worry so much, wait for me outside with peace of mind!"

The husband and wife glanced at each other, and couldn't think of anything to refute their son for a while, so they could only give up.

But what they didn't know was that the reason why Lu Heng refused to let them go in with him was mainly because he was worried that he would obstruct him when he scolded people later.

There was a creak, and the wooden door of the small courtyard, which had not been opened for a long time, was pushed open again.

This time was different from last time, as soon as Niu Laohan heard the sound of opening the door, he instantly ran to the door in a hurry.

"Young Master, are you back?"

Old Man Niu was happily about to ask something, but when the door opened, he found a group of people standing outside.

Moreover, all of them look quite wealthy.

He was a little dazed for a moment.

Seeing this, Lu Heng took two steps forward, smiled at him, and said:

"Niu Laohan, these are the big people I brought to see the potatoes."

"As for what their identities are, you don't care, just call them nobles."

"By the way, the potatoes that were left in the field before haven't grown, you should confiscate them, right?"

The old man Niu, who was originally at a loss, heard him ask about this, and immediately left his previous doubts behind.

"Ouch, young master, I was just about to tell you about this, but they all said that you were not at home!"

He slapped his thigh and said:

"I think I should be able to accept it, but I can't get an idea if you're not there, so I haven't moved. It's just so that you're here today, so let's harvest all the potatoes together! ”

Lu Heng nodded with a smile and agreed.

When the old man Niu ran to the side of the courtyard wall to get a hoe, he turned his head to look at Li Shimin.

"Your Majesty, this is an old farmer carefully selected by my father from the tenants of the family, he is very experienced in serving the crops, and in the past three months, the old man Niu has been staying here and has never returned home."

"When the time comes, if potatoes can enter your eyes, the minister hopes that he will also get the reward he deserves."

"After all, if you rely on the ministers themselves, it is not certain whether these potatoes can be planted or not."

Lu Heng's idea was simple.

Since Niu Laohan has paid so much for the potato matter, and these things are not within the scope of his original work at all, then what he can get, he must fight for the other party.

Hearing his words, His Majesty Li Er raised his eyebrows and nodded in agreement.

"It's a reasonable request, and I'll be able to grant it."

"But only if you can prove it."

Lu Heng grinned, patted his chest and said:

"I'll do it, don't worry!"

Under his leadership, a group of people walked into the small courtyard one after another.

When he entered, Niu Laohan was already holding a hoe and standing next to the cultivated field with great interest, just waiting for Lu Heng's order, he could start digging.

With the experience of the last time, this time Lu Heng was much more direct.

"You can stand by and watch him dig."

Lu Heng looked at Li Shimin, he didn't call Your Majesty.

Since he didn't tell Niu Laohan the identity of this group of people at the beginning, for fear of scaring the other party, there is no need to rush to explain it now.

His Majesty Li Er readily agreed, and did not dislike the very muddy ground caused by the snow on the ground, even if his boots creaked when he stepped on them, and he was soaked in snow and muddy water after a while, he did not have the slightest temper, but smiled happily.

He read and spoke:

"This ...... Niu Laoman, this crop called potatoes is very novel, and it can be harvested in such cold weather. ”

"Before that, I thought that only the vegetables grown next to the hot springs could be harvested in the month of Layue!"

Niu Laohan didn't know who he was, he just thought that he was a nobleman with a good temper and approachability.

Seeing that Li Shimin was so interested, he was also happy to explain:

"Oh, noble man, don't you know, I heard the young master say that this potato can be harvested in the lunar month, and I was also scared!"

"The most important thing is that this artifact can be planted two or three times a year, the shortest is two months, and the longest can be harvested once in more than three months."

"The high yield is terrifying! I know the yield per mu of this kind of farm work, at least three or four thousand catties, if you count more, then maybe how much! ”

Li Shimin's brows kept jumping when he heard this.

Although Lu Heng had already laid the groundwork for him with this crop three months ago, he still felt outrageous when he heard the yield of three or four thousand catties now.

I didn't expect that as soon as this old man was exported, the output would be even more outrageous!

The two of you said a word, and they talked a lot back and forth, and in the middle of this talk, the old man Niu had already dug out the first potato plant in his hand.

Complete, whole potato!

Seeing that he dug it out, Lu Heng said loudly beside him:

"Hey, old man Niu, you give the potatoes to the noble man next to you to weigh them!"

"By the way, are there any scales in this yard? If you have one, you can find it and measure it directly with a scale, so as not to feel inaccurate. ”

Niu Laohan honestly agreed, handed the potatoes to His Majesty Li Er next to him, and then ran to the yard to rummage through the scales.

When he walked to the front wing.

The group of people who followed Lu Heng in all gathered around Li Shimin at the same time.

Cheng bites the golden monkey and says urgently:

"Your Majesty, you weigh the minister, no matter how you say it, the minister is also a general, he has a lot of swords, guns and sticks, and he naturally knows the weight of his hand better than others!"

Li Shimin glared at him.

Who the hell wasn't a martial artist before!
