There are still many days before March, and during this period of time, Zheng Liwan stayed very happily in the East Palace, mainly chatting with Wu Zetian and the two, and also gradually deepening her relationship with Li Chengqian.

On this day, Li Chengqian, Wu Zetian, Zheng Liwan and others were walking in the back garden.

Recently, the temperature has been rising, and the signs of spring are becoming more and more obvious.

The three of them talked and laughed, and the atmosphere was very harmonious.

It is rare to have such an atmosphere, Li Chengqian originally thought that Wu Zetian would be jealous, but now it seems that he is thinking too much.

There are also a large number of guards around to protect him, and after what happened last time, Li Chengqian was afraid.

Suddenly, Guan Lux came to report.

"His Royal Highness the Crown Prince, the third prince and the fourth prince ask to meet!"

When Li Chengqian heard it, these two boys are not in the Ministry of Science and Technology, what are they doing in the East Palace?

"Oh? Let them in. ”

At this time, Li Ke and Li Tai came in.

"Big brother! Sister-in-law! ”

The two said in unison, and at the same time, they also discovered Zheng Liwan's whereabouts.

Regarding Zheng Liwan's appearance, the two brothers stared at it tightly, just like their father Li Shimin.

These two stinky boys dared to stare at their own women.

Li Chengqian coughed twice, and the two of them eased up.

"Who is this?"

Li Ke asked first.

Wu Zetian sees these in his eyes, and there is no man in the world who will not be moved when he sees Zheng Liwan, and these two brothers are the same.

She responded on behalf of Li Chengqian: "This is Zheng Liwan, the future concubine of His Royal Highness the Prince, and she will be married in March." Your future sister-in-law! ”

As soon as Wu Zetian's words were finished, the two brothers felt rude. It turned out to be Li Chengqian's concubine!

Li Tai first said: "Tai'er has seen the future sister-in-law!" ”

"It turns out that you are Zheng Liwan, it is really better to meet than to be famous! It's really shocking to see it today, big brother is so blessed! ”

Li Tai also said: "Yes, after the eldest brother married the great beauty princess, he has to marry such a beauty, what a blessing!" ”

Two brothers, you say everything to me, which makes Zheng Liwan a little shy.

"The two princes praised it falsely, the little girl can't stand it!"

"In the future, you are our sister-in-law, so you should be!"

Li Ke said again.

"You two stinky boys, when did your mouth become so sweet?"

Li Chengqian asked.

Li Tai laughed.

"I still learned it with my eldest brother, but it's a pity that I can't learn the essence and can't find such a beautiful woman!"

There is a sour meaning in these words.

Li Chengqian gave them 10,000 in vain.

"It seems that you have grown up, and when you go back to the king and His Majesty's queen mother, let you get married earlier, so that you can settle down, don't think nonsense."

Li Chengqian said.

The two said bluntly: "There are not many talented and good-looking existences like the two sisters-in-law." ”

The words of these two made Wu Zetian and Zheng Liwan's faces red.

Wu Zetian said: "Two princes, I know a few talented women, maybe you can recommend them?" ”

Li Ke said: "This has to be checked by the eldest brother, as long as the eldest brother says yes, it is okay." ”

"Good! This king will promise you, go back and ask your sister-in-law to pay attention to you, it seems that you are about to grow up. ”

"Thank you so much, big brother!"

The two saluted.

Li Chengqian knew that these two people didn't just come here to see Zheng Liwan.

So he asked directly: "You came to the East Palace to find this king not only for the sake of the female dependents, right?" ”

They smiled!

Li Taixian says:

"Yes, I can't hide it from my eldest brother! Recently, we have started to study trains, and we have built a lot of trains, but we have encountered problems in iron ore. Because the demand was too large, there was no supply for a while, and there were many problems in transportation. ”

It turns out that this is the case, the minerals needed for the railway are very huge, and the iron stock in Datang is not enough at all, even if there are Turkic people to mine it, it is far from enough.

Therefore, the two brothers Li Ke came to the East Palace to ask for help.

If that's the case, that's a big deal indeed.

Li Chengqian thought for a while, and then ordered: "Guan Lishi take out the map!" ”

Guan Lux took out the map, and Li Chengqian spread it on the table.

Everyone looked at the map on the table, and they couldn't see why.

What can this map do?

Nobody knows.

Even Wu Zetian didn't know what Li Chengqian wanted to do.

And Li Chengqian looked there for a while, staring at the map, looking at it with a fascination.

Suddenly he screamed.

"There's a way."

When he screamed, he attracted everyone's attention.

They asked in unison, "What way?" ”

Li Chengqian pointed to the map, and everyone was still confused.

Li Chengqian smiled and said: "You see that this is Guannei Road, and this is Shannan Road, these two roads are rich in iron ore, and at the same time, there are sufficient waterway resources, and the waterway will eventually flow into Chang'an, and what we have to do is to integrate the nearby iron mines through the waterway!" ”

As soon as these words came out, everyone suddenly realized, but Li Ke said: "This is feasible, but the iron ore is very heavy, and ordinary ships are not able to carry too much ore, so there is still no problem solved." ”

"Yes, eldest brother, the third brother is right, if so, we might as well use horses to transport them directly? It could be faster. ”

Li Chengqian smiled.

"You just don't know how to work around, where is your research on steam engines?"

The two were puzzled.

What's the matter with this steam engine?

"Please solve your doubts, big brother!"

"I want you to build a steamer!"

"Steam engine steamers?"

"That's right, use the steam engine as the power, and the problem will be solved!"

The two exclaimed.

"Why didn't we think of that?"

Anything as complex as a train can be studied, and a ship is even more difficult to learn because it has a simpler structure.

"Therefore, if you want to do things in the future, you must think more comprehensively, and you must understand how to think of solutions when you encounter problems, after all, there are always more ways than problems."

The two responded: "Big brother teaches yes!" ”

From this one thing, Li Chengqian's knowledge is still Li Chengqian's, his height has surpassed everyone by a lot, and his two younger brothers cannot catch up.

"Okay, you guys go and deal with it, the Datang Frontier still needs to build a railway! Iron ore can't be broken! ”

"Yes! Eldest brother. Then let's go first! ”

The two saluted Wu Zetian and Zheng Liwan again, and left the East Palace.

As soon as the two of them left the East Palace, someone came to the East Palace again.

A little yellow door has come to report.

What a time to spare!

made Zheng Liwan a little dumbfounded, it turned out that the prince was so busy, no wonder Wu Zetian asked himself to help him too.

Li Chengqian has long felt that these things are normal.

Without these things, he still feels unhappy!
