Liu Ying was stunned at first, and then suddenly suddenly.

yes, how did he forget such an important thing!

After Liu Feng came, his father-in-law had seen him in person, and he was there at that time!

The father-in-law asked Liu Feng a lot of words, although Liu Feng was vague, but between the words, he was very respectful and admired the princess of Qin.

also said that he was able to burn the glass this time, thanks to Princess Qin.

The princess of Qin is said to be very fond of reading, and after reading the agricultural book, she also improved the existing plough, allowing people to create a kind of deep plough to make His Majesty happy.

Even the cement before it is said to have come up with it after reading the book.

Such a powerful character, how can he care about a Liu Feng?

Liu Fang saw that he had figured it out, and then continued: "When Your Majesty let Liu Feng enter the military battle, King Qin didn't stop him. When Wu Da was eyeing Liulifang, King Qin was not polite to him. ”

When Liu Ying heard this, she was even more sure in her heart.

Since King Qin didn't stop Liu Feng from entering the battle, he must not care about a little person like Liu Feng.

To be more precise, even if Liu Feng is gone, it will not have any impact on Princess Qin's Liulifang.

In this way, how could Princess Qin be dissatisfied with them because of Liu Feng?

Thinking of this, Liu Ying breathed a sigh of relief.

He smiled and admitted his mistake: "It's the son who thinks about it, thanks to the father-in-law who gave him advice and solved his son's doubts." ”

Liu Fang nodded with satisfaction: "Well, it's good that you can figure these out." You have to remember that what we have to do now is to do a good job of the errand assigned by His Majesty. Your Majesty is willing to trust us, and we cannot let Your Majesty down.

This clairvoyance is very important, and this glass lens is the most important thing, you must keep an eye on it, and you must not make a mistake!

As long as we get this done, Your Majesty will definitely remember our merits and will not treat us badly. ”

"Don't worry, father-in-law, son must be careful to watch!"

"We know you're a good boy, go get busy."

"My son obeys!"

……

In the Qin Palace, Su Jinli didn't know about the intrigue between Liu Fang and Wu Da.

She's been busy with mirrors and farm things lately.

Liulifang is processing and creating mirrors, although the finished product is not very satisfactory to her, but Liulifang is on the right track.

The matter of "Wenkui" magazine, she handed over to the Zhou manager of the Zhuangyuan Library, and now she is preparing closely, so she doesn't need to worry.

But it didn't go well on the farm side.

Exactly, it's a matter of farm tools.

Her farm has a total of 10,000 acres of fields, and the number of ploughs needed is not small. There are fewer ploughs, and there is no time to reclaim the farmland, which is destined to delay spring ploughing.

However, the speed of this plough is too slow.

Now, several days have passed, and only thirty sets of deep ploughs have been received. These thirty sets of ploughs, at least half of which are scored in Chu Yan's farm, where is the enough point?

Su Jinli didn't want to go to the blacksmith shop to ask in person, so he had to ask Cinnabar to ask and see if there was a way to increase his speed.

Cinnabar knew that she was very concerned about the plough, so after going out to ask, she hurried back.

As soon as she entered the house, she said, "Master, the slaves and maids have inquired. When building a plough, you need to keep hammering and forging, otherwise it will easily break, so it takes a lot of time. ”

Su Jinli was stunned when she heard this: "Keep beating? Can't you just cast it? ”

"Pouring molding?" This time she was stunned by Cinnabar, although she was the niece of a military general, she really didn't understand the matter of forging farm tools, "Master, what does this mean?" ”

Su Jinli said casually: "It's just to make a sand mold, and then pour molten iron into it, and wait for it to cool and solidify, and then trim the shape." In this case, the speed should be much faster. ”

"I'm afraid it won't work."

Chu Yan suddenly walked in from outside.

He glanced at Ping'an and Cinnabar, and said lightly: "This king and princess have something to say, you go out first." ”

The stakes are so high that these slaves and maids should be made aware of this?

Thinking of this, Chu Yan glanced at Su Jinli a little helplessly.

He didn't expect that Su Jinli actually knew about forging. Good thing he heard, otherwise she would have been in trouble if she had said more.

Seeing that his face didn't seem to be very good, Ping'an and Cinnabar didn't dare to stay longer, so they retreated decisively.

Cinnabar also closed the door by the way, and then pulled Ping An away so as not to hear something that should not be heard.

Seeing her serious face, Ping'an couldn't help but ask her: "Sister Cinnabar, what do you say the prince wants to tell the master?" ”

"That's not what you're supposed to ask." Cinnabar looked at Ping An warningly, "Ping An, you have been with your master for much longer than me, but if there is, I can't help but say it."

The master's current identity is different from before, and although her current identity is noble, it is also easier to be targeted.

Therefore, those of us who are slaves and maids, change our words and deeds, and if we accidentally say the wrong thing, it will affect our master, but it is your and my sin. ”

Ping An was suddenly awe-inspiring, and hurriedly promised: "Yes, I won't ask in the future." ”

At the same time, in the study.

Chu Yan looked at Su Jinli curiously: "Su Bao'er, do you still know about forging?" ”

Su Jinli knew that this matter was a forbidden area, so she deliberately said, "Didn't Ah Yan send some books before?" I flipped through it and found that it happened to talk about wrought iron, so I wrote it down. ”

Wrought iron or something, she naturally knew it for a long time.

But Su Xinai is a military general, and this identity is too sensitive, so she deliberately lied.

Anyway, Chu Yan did send a lot of books over, and it did talk about wrought iron, she said this, not afraid of Chu Yan's suspicion.

When Chu Yan heard her words, he was even more surprised: "Have you finished reading those books?" ”

Su Jinli decided to be modest: "Not yet, but it just happened to turn over." ”

She really turned it over, after all, to survive in this era, and she plans to build more, she must understand the current situation.

Just like this time, she happened to have read the wrought iron and steel-making methods recorded in the book, and she could use it.

If she hadn't just seen it, wouldn't she be suspicious if she said she knew how to make steel?

Chu Yan secretly breathed a sigh of relief.

He hadn't finished reading those books, if Su Jinli had really read them all, wouldn't it seem that he was too useless?

However, Su Jinli's speed of reading books is inevitably too fast!

Chu Yan suddenly felt that he had to find a time to read all those books. Otherwise, if Su Jinli said something in the future, he didn't know, wouldn't Su Jinli dislike him?

Su Jinli didn't know what he was thinking, she asked directly: "You said no just now, why?" Pouring directly with sand molds, the speed will definitely be much faster. ”

"Of course not, as for the reason...... Chu Yan suddenly laughed, "If you are a pro-king, this king will tell you." ”
