Luzhou City Sewer Project, two years.

It will take two or three years to train five little ones who have just graduated from Chen Qian, and at least they will not be able to really come in handy until they are eighteen or nineteen years old.

Improving papermaking ...... I'm afraid this is endless.

Inventing a truly reliable and usable movable metal type...... God knows when it will be successful!

Mathematics textbooks, the elementary school level should be almost written, and the next junior high school level should be able to make up the work? But if I write later, I'm afraid I can only remember as much as I write.

And also......

"No, no, it can't be anymore!"

In his study, Li Yuanjia looked at the words he had written on the white paper, and shook his head vigorously - plus the previous coal stove, iron pot, stir-fry and thirteen spices or something, especially after adding the Quyuan plow, these things taken out are already powerful enough, and it is better to slow down other things.

So how should we spend the next two or three years?

Lying on the hard table, Li Yuanjia began to be stunned in a daze.

If his memory is not wrong, in the next two or three years, "himself" will face two major events. The most important of these is, of course, the father who is far away in Chang'an...... That is, the death of Emperor Li Yuan, Li Yuanjia remembered that it should have been in the past two years. The second is to marry the daughter of Fang Xuanling, a major minister of the Tang Dynasty and a famous historical minister......

"Well, I don't know what she looks like now."

Thinking of his wife, Li Yuanjia couldn't help but sigh again.

If it was possible, of course he didn't want to marry a girl he hadn't seen a few times, and he had married the other party when he was fifteen or sixteen years old. But there is no way, who let this marriage be determined above? This year, he wants to refuse the marriage designated by the emperor, not to mention that he is a king who has no real power, and even his eldest nephews have no ability.

The only thing to be thankful for is that she married Fang Xuanling's daughter.

That is the prime minister that Li Shimin really trusts, and there is no stain except for giving birth to Fang Jun's wonder, and the daughter who must be taught should not be bad. And with the old man Zaifu of the dynasty, Li Yuanjia can also have more sense of security, which seems to be very good?

"Huh? That's not right! ”

Just when Li Yuanjia was fantasizing about the appearance of his future wife in his mind, a thought suddenly rushed in, which made him stunned for a moment.

It seems a little wrong!

In the next two or three years, my father is likely to die...... Regardless of whether Li Yuanjia can return to Chang'an or not, he believes that he should not be able to change this history! And in the next two or three years, he will marry a wife!

So the question is, which one will come first?

If it is to marry a wife first, it will have no effect, but if the death of the father is in advance, does Li Yuanjia have to keep it for three years...... No, more than two years of filial piety to be exact?

"I'll go, and this problem is there!"

Straightening up from the desk, Li Yuanjia's eyes began to flicker frequently, thinking about the relationship between these two things, as well as the various possibilities that will appear in the future......

"Boom! Boom! ”

Just when Li Yuanjia was just beginning to ponder the connection and possibility of these two things, the door of the study was suddenly knocked on from outside. Li Yuanjia blinked, first let his thoughts back, and then said loudly: "Come in!" ”

After the door opened, Han Shan walked in quickly, and Shi Li said, "I've seen the king......"

"Alright, what's the matter?"

Waving his hand impatiently, Li Yuanjia interrupted Han Shan's words.

Hearing the king's tone that didn't seem to be very good, Han Shan felt a sigh in his heart, knowing that Li Yuanjia must not have much patience at this time, so he hurriedly said respectfully: "King, Chen has joined the army here, and he has brought more than a thousand catties of iron!" ”

"Oh? So fast?! ”

After listening to Han Shan's words, Li Yuanjia was suddenly overjoyed, and stood up from the chair with a sigh.

More than 1,000 catties of iron? It's just the right time!

Feeling refreshed, Li Yuanjia waved his hand and said, "Let's go, go and have a look!" ”

followed Han Shan to the treasury of the government office, and saw more than a dozen strong men carrying heavy iron pieces into it, Li Yuanjia immediately put aside the troubles just now, and was overjoyed: "Yes, with these iron materials, the construction of those tools can start as soon as possible." ”

"I've seen the king!"

When their voices were heard, the crowd saluted.

Waving his hand to let them get up, Li Yuanjia looked at Chen Zhi and said with a smile: "Chen joins the army, this time the iron material is sent so quickly!" But that friend of yours helped a little too? ”

"Back to the king, exactly."

The corners of his eyes jumped twice, and Chen Zhi hurriedly replied: "This time I sent a total of 1,200 catties of iron, I believe it should be used for a while." In half a month at most, we can send another thousand catties to the king. ”

"Haha, good!"

Li Yuanjia nodded and smiled: "If there is no iron material for Chen to join the army this time, it will be impossible to complete the sewer system of Luzhou City within two years." ”

"It is Chen Zhi's blessing to be able to share the worries of the king."

Taking a deep breath, Chen Zhi hurriedly expressed his heartfelt and modest expression.

But before he could say anything more, he saw Li Yuanjia raise his eyebrows, and then said with a smile: "Chen joins the army, I still have something here that I want to ask you for help." ”

This was said very politely, so Chen Zhi hurriedly bowed slightly, and said respectfully: "The king, please say, if Chen Zhi can do it, he must go all out!" ”

"It's very simple, borrow some people to use it."

Smiling slightly, Li Yuanjia said gently: "I want these iron materials to make tools for the people who build sewers, but just with the blacksmiths and carpenters of King Xu's Mansion to build the tools used by two hundred people, I don't know how long it will be delayed." I know that the Chen family is a big family in Luzhou, and there is also an iron-making workshop, I wonder if I can borrow some people to use it? Haha, it doesn't take too much, two or three people each from the blacksmith and the carpenter are enough. ”

"This ...... Of course. ”

When answering Li Yuanjia's words, Chen Lin's voice instantly became a little dry.

No way, does he dare not agree?

In fact, the carpenter is not enough, even if he is not enough, he will definitely be able to find it for King Yu in Luzhou. But if the blacksmith is concerned, Chen Lin can really only be transferred from his own iron-making workshop - although he knows that the workshop is not manpowered, if he sends these two or three people to King Xu, it will definitely have an impact, but since Li Yuanjia has opened his mouth, he has no reason to refuse such a small matter.

It's just that looking at the smiling expression of King Yu, I don't know why, Chen Lin's heart suddenly jumped!

I always feel that something seems wrong?
