If possible, Li Yuanjia really wanted to go back to Chang'an to see his mother's situation.

Although in this era, there is no MRI, no B-ultrasound, not even a stethoscope and thermometer, not to mention all kinds of chemical drugs, but as a former doctor, even if he only makes a highly subjective diagnosis and gives some advice on diet and exercise, it should be somewhat effective, right?

It's just that Li Yuanjia also knows that this wish is quite unrealistic.

Not to mention that he was just sick, he didn't even know if he would have a chance to go back when the emperor and the imperial concubine died in the future. After all, Li Yuanjia is only the emperor's younger brother, not Li Shimin's son.

And......

From the bottom of his heart, Li Yuanjia is not willing to return to Chang'an, which is prosperous but cold to him. Although he was very bored in Luzhou, he couldn't even find a person who could talk and eat on an equal footing, but Li Yuanjia was even more uncomfortable in that place in Chang'an.

So after hesitating for a while, Li Yuanjia simply overturned his idea of sending the horseshoe and Quyuan plough to Chang'an together - obviously the effect of this thing on the Tang Dynasty was far less important than Quyuan plow, at least the person sent by Li Shimin did not say that he wanted him to bring this thing over.

Of course, it may be that the second brother doesn't know that there is such a thing?

So after thinking about it, Li Yuanjia still decided that as long as Lao Li didn't take the initiative to ask for it, he wouldn't take the initiative to send new things to Chang'an. If no one notices, let it sit silent in the palace for a few years......

"Great, King!"

Just when Li Yuanjia's mind changed for a while, Han Shan, who got the news, ran over panting, and asked urgently, "Have you seen the king...... But is Chang'an coming? What's the matter? ”

The last letter made Li Yuanjia go on a hunger strike for three days, but Han Shan was frightened.

What he is most afraid of now is worse news from Chang'an, such as the aggravation of the imperial concubine's condition and even ...... Anyway, as long as he thought about this possibility, and the serious consequences it would bring, Han Shan shuddered.

Without answering Han Shan's question, Li Yuanjia waved his hand directly and said, "Old Han, let Chen Mu prepare five Quyuan plows, and I will do it tomorrow!" Also, prepare a few cars...... Find a few more shrewd guards, and go to Chang'an tomorrow with the carriage and Quyuan plow! ”

"Qu Yuan plow? Changan? ”

After listening to Li Yuanjia's words, Han Shan was stunned for a moment.

"Yes, Chang'an, someone wants to see it."

Li Yuanjia's flat words made Han Shan's two pupils shrink suddenly, and he immediately understood what was happening.

He'd seen that thing before.

Although he didn't really understand how his own king could make this thing, it didn't prevent Han Shan from knowing what a divine thing it was after seeing a cow pulling a Quyuan plow in the field! So as soon as he heard that someone from Chang'an wanted to qu yuan plow, Han Shan suddenly understood who sent the so-called person who came - who else could instruct a prince this year?

Oh my God, even the emperor knows about that thing?

Secretly swallowing his saliva, Han Shan didn't dare to slack off, and immediately nodded and said: "Yes, king, I will immediately send someone to Zhuangzi to pick it up, and I can pull it back at night!" The carriage and the guards will be ready tomorrow morning! ”

The current Quyuan plough in the house is definitely not enough for five units, but there are a lot of Chen Mu who have been sent to the three Zhuangzi after Chen Mu has done it before, so just send someone to get it. As for the carriages and guards that transport the Quyuan plow, the palace will naturally not be lacking.

However, as soon as Han Shan wanted to prepare, he was stopped by Li Yuanjia again: "By the way, there is one more thing!" Lao Han, when you ask people to go to Zhuangzi, find two farmers who can use Quyuan plows, and let them set off with them tomorrow! ”

"Farmers? Let them also go to Chang'an. ”

"That's right, find someone who can use a curved plow!"

Taking a deep breath, Li Yuanjia said in a deep voice: "Tell them, don't worry about the matter of cultivating the land, and send someone to help them take care of it." And tell them that when they come back, the king will reward them with money and food, and they will not lose anything to them......

"Yes, King!"

Taking a deep breath, Han Shan immediately left in a hurry.

Although Li Yuanjia's requirements are not high, that is, a few plows, a few carriages and a dozen people, don't forget, this is to be sent to the emperor!

There is no trivial matter in the heavenly family, how dare Han Shan slack off?

Therefore, Quyuan plough naturally chooses the five most beautiful and sturdy sets made by Chen Mu; The guards should choose the most clever, of course, they must also be responsible, and they can bear something on the road; Of course, there are also candidates such as the coachman who the king didn't notice, and Han Shan also has to pick a few of the most stable, and he won't dare to have problems on the road.

As for the farmers who went to Chang'an, Han Shan felt even more headaches.

It is very likely that he will meet the emperor, Han Shan is afraid that those soil buns who have never even seen the seven-rank officials will cause trouble for the king when the time comes, in case he says something that should not be said, or does something that should not be done, let the emperor turn his anger on the king, it will be bad!

So Li Yuanjia said to let him send someone, but how could Han Shan rest assured? I have to make a trip myself......

……

"Alas......"

After watching Han Shan leave, Li Yuanjia stood under the big tree in the courtyard and sighed softly.

I have to say that he still underestimated the power of Qu Yuan plow.

Thinking about the cheap second brother who was in a hurry to send someone to Luzhou to pick up things and go back, Li Yuanjia couldn't help but sigh again: "Alas, I can't help it, if only I took it out two years later." ”

He really didn't expect Lao Li's reaction to be so fast!

And Li Yuanjia originally thought that if Chen Mu wanted to get this thing out, it would take a year or two to completely perfect it, and it would definitely take longer to completely perfect it, but he didn't expect that it would take more than half a year to achieve this level, and he directly pressed the straight plow on the ground and rubbed it!

According to his idea, it is actually a step by step.

In the first few years of arriving in Luzhou, in fact, he was accumulating strength, so in addition to iron pots, tables and chairs, which Li Yuanjia couldn't wait for at all, whether it was cotton, papermaking, metal type, ink, he didn't have the slightest impatience, but slowly spent money and let the craftsmen slowly study - except for occasionally pointing out their methods of doing "scientific research", Li Yuanjia rarely even made any specific suggestions.

There is only one ultimate goal, and that is to become a different Prince of the Tang Dynasty!

To put it bluntly, it is to realize the wish of the "third way", not to be a prince and assassin for the rest of his life. For this dream, Li Yuanjia prepared the blank books in his study, asked for several craftsmen from his uncle, and even forced two literati in the house to help him teach people to read and break......

But after thinking about it for a while, Li Yuanjia suddenly smiled and said to himself: "Forget it, it's all taken out anyway, can it still be taken back?" ”

With a shake of his hand, Li Yuanjia walked into his study.

Instead of worrying about this, worrying about that, it's better to write something again. Recently, Li Yuanjia has been in a good state, and he has remembered a lot of things one after another, and he sees that the latest mathematics textbook is about to be completed......
