.“ Open...... Father, this reading glasses has nothing to do with Li Xianjiu, but was offered by a wandering magician, and after the person sent some ways to use the lenses, I asked Li Xianjiu to find someone to polish a lot of lenses. Pen? Interesting? Pavilion wWw. ｂiquge。 info" Princess Pingyang said in a low voice with a flushed face, she had never lied to Li Yuan since she was a child, this was the first time, and she felt very awkward.

Seeing his daughter's appearance, Li Yuan couldn't guess that she was lying, and with his understanding, it was probably that Li Xiu didn't want this credit, so he forced it out, and it was not the first time he had done this kind of thing, but he didn't expect that he could convince his daughter to help him lie this time, which also made Li Yuan a little angry.

But angry is angry, when looking at the clear picture in front of him through glasses, Li Yuan couldn't help but feel impressed by Li Xiu's talent, this young man seems to have endless novel ideas, and he also knows many things that others don't know, sometimes even Li Yuan wants to know where he learned these things?

In fact, not only did Li Yuan see that Princess Pingyang was lying, but even Li Chengdao next to him could also see it, and he was sure that this reading glasses must have been made by Li Xiu, because he remembered that when he visited him that day, he and a beautiful little girl were playing with these lenses, but he didn't expect these lenses to have such a purpose.

"Dao'er, you go out first, I have something I want to talk to your aunt!" I saw that Li Yuan thought about it for a long time, and finally suddenly said to Li Chengdao.

"Huh?" Li Chengdao was reluctant when he heard this, because his grandfather had not yet given an answer to his request to go out to study with Li Xiu just now, but now he wanted to drive himself away, but he did not dare to disobey his grandfather's order, so he had to agree sullenly and turned to leave.

After watching Li Chengdao leave, Li Yuan waved away the chamberlains and palace maids in the hall, and then looked at Princess Pingyang for a while, then sighed and said: "Sanniang, our father and daughter haven't talked for a long time, you can sit down and chat with your father for a while!" ”

Princess Pingyang was stunned for a moment when she heard her father's words, and then agreed to sit next to Li Yuan, and before he could speak, she saw Li Yuan take the lead and said, "Sanniang, what do you think of Li Xiu?" ”

"Why would my father ask that?" Princess Pingyang was a little worried when she heard this, she also knew that her father must have seen through the lie just now, she was not afraid, but she was worried that he would blame Li Xiu.

"When my father first heard the name Li Xiu, he was out of the house because of a woman, and later he offered the technique of wound suturing and cured your injury, but he beat Chai Shao again, so my impression of him was not very good, but at the banquet on the first night of the year, he successfully showed his literary talent, and I was also impressed by him."

When he said this, he saw Li Yuan suddenly pause and then continued: "But he is a very strange person, it seems that he really has no intention of fame, I don't want the credit for designing the waterwheel last time, and I don't want the credit for reading glasses this time, some time ago, Erlang offered the strategy of splitting the Turks, and this time to guard against Tuyuhun, there is his figure behind him, I was going to give him a reward, but I didn't expect him to enter your mansion first to make sacrificial wine, although it is the official position of the fifth grade, but it is a false title, which makes the father very difficult to figure out." ”

"Father, in fact, Li Xiu's idea is very simple, he really has no intention of fame and fortune, but he has a heart of worrying about the country and the people, so when the court encounters some difficulties, he can't help but do what he can." Princess Pingyang explained with a smile that after this period of getting along, I am afraid that no one understands Li Xiu's thoughts better than her.

"It's as simple as that?" Li Yuan obviously asked rhetorically with some disbelief, he has seen all kinds of people, but he has never seen a person like Li Xiu, although there are also some people who claim not to be fame and fortune, but most of these people are people who sell fame and reputation, and there are few people like Li Xiu who are really not for fame and fortune, or even hide from fame and fortune.

"Li Xiu is such a simple person, this daughter can be guaranteed with her life!" Princess Pingyang was very sure, and was even willing to guarantee with her life, which also made Li Yuan stunned, and her eyes at her daughter also had a somewhat inexplicable look.

"Sanniang, Dao'er came to me just now and asked me for something, but I was hesitating just now whether to agree to him, you can help me think about it!" Li Yuan suddenly changed the topic at this time.

"What made my father hesitate so much?" Princess Pingyang also said curiously when she heard this.

"Hehe, in fact, this matter is also related to Li Xiu, Chengdao saw Li Xiu at your place a few days ago, and was also impressed by his knowledge, so he wanted to go to you more to ask Li Xiu for advice, but your eldest brother disagreed, and he ran to me." Li Yuan explained with a smile, in fact, he also planned to reject Li Chengdao just now, but after what happened just now, he suddenly changed his mind.

"Let Dao'er go and ask Li Xijiu for advice?" Princess Pingyang's eyes suddenly lit up when she heard this, and she immediately nodded in agreement, "This method is good, Li Xianjiu is erudite and talented, and I saw that he and Dao'er were also very good at talking that day, if Dao'er can ask him for more advice, it will definitely be of great benefit to Dao'er's studies!" ”

Emotionally speaking, Li Xiu and Li Chengdao are the closest people to Princess Pingyang, and Li Chengdao studied from Li Xiu, she can also see this nephew from time to time, and even from the utilitarian side, Li Chengdao is likely to be the future prince, Li Xiu can lay a relationship foundation with him, and will also improve his status, so as to make up for the identity gap between him and himself.

"Hehe, I knew you would agree, in that case, let Dao'er go to Li Xiu every few days to ask for some questions, but you also have to supervise more, don't let Dao'er waste his studies!" Li Yuan saw his daughter's happy appearance, and smiled slightly, being able to make his favorite daughter so happy is enough to show that the decision he made was correct.

After chatting about business, Li Yuan's father and daughter talked about some family matters, but at this time, Princess Pingyang suddenly thought of something, and immediately took out a short cylinder from her arms and said to Li Yuan: "Father, my daughter forgot to say one thing just now, in addition to the reading glasses just now, those lenses have another function, such as this telescope!" ”

"Telescopes? What is it used for? Li Yuan looked at this cylinder and asked suspiciously.

"Giggles, just listen to the name, this thing is used to see the scenery in the distance, father, you can try it!" Princess Pingyang said and opened the cylinder and took out the telescope inside, this telescope was designed by Li Xiu himself, divided into three sections, which can be retracted, so that it is convenient for users to carry.

I saw Princess Pingyang pull the telescope open, and then adjusted it to let Li Yuan look outside the palace door, but Li Yuan was also startled at first, the scenery outside the hall was so clear that he could even see a fly on the back of the guard outside the hall, it was like a legendary clairvoyant.

"It's amazing, it's ...... Is this some kind of spell? Li Yuan finally showed a little surprise at this time, he and Princess Pingyang are worthy of being father and daughter, and they all had the same reaction when they saw the telescope for the first time, after all, except for the legendary spell, he really couldn't figure out the truth.

"Giggles, I also said this like my father at the beginning, but Li Xianjiu told me that this is actually the effect achieved by combining two lenses, which can make the distant scenery very clear, so it is called a telescope!" Princess Pingyang smiled coquettishly again, she rarely saw her father's surprised expression, but while she was happy, she said that she leaked her mouth and confessed Li Xiu.

"I see, I didn't expect two small lenses to have such a big effect, if the generals in the army were each equipped with a telescope, wouldn't they be able to detect the enemy situation in advance!" Li Yuan also began to get excited at this time, he is a hero who only seeks results and does not care about the process, the principle of the telescope is not important at all in his opinion, what matters is the role of the telescope.

"The father is wise, and the daughter thinks the same way, but to make the lenses, you need to use pure and transparent water jade or medicinal jade, both of which are relatively rare, so I am afraid that they cannot be manufactured in large quantities." Princess Pingyang expressed her worries at this time, needless to say, glass has always been controlled by overseas businessmen, as for crystal, there was also no large-scale mining during the Tang Dynasty, and the output was also very scarce.

"This is a problem, but only this thin lens is needed to make a telescope, and although there are many generals in my Datang, there is no need for everyone to be equipped with a telescope, so let people collect some materials first, and make a batch of rewards for those meritorious generals, so that you can play the role of a telescope, and you can gather the hearts of military generals, and inspire other military generals to make meritorious contributions to my Datang!" Li Yuan is worthy of being the founding emperor of the Tang Dynasty, and he came up with a way to kill three birds with one stone just from the telescope.

When Princess Pingyang heard this, she couldn't help but be surprised, because Li Yuan's words were almost exactly the same as Li Xiu's plan in advance, and it seemed that he and his father almost thought of going together, so she immediately nodded in agreement, and then offered Li Xiu's telescope making method that Li Xiu had prepared a long time ago, as well as a simple definition of the lens power, so that the craftsmen of Datang could make qualified lenses.

It wasn't until it was getting late that Princess Pingyang had dinner with Li Yuan again, and then she got up and left the palace and went out of Chang'an City, but she didn't go to her own courtyard immediately, but took a detour when she went back and went to Li Xiu first.

At this time, it was already the beginning of the night light, Li Xiu and Qi Niang had just had dinner, he was about to teach Qi Niang some things, but he didn't expect Princess Pingyang to come to visit, so he immediately came to the front yard to greet him, and as soon as Princess Pingyang met, he told her about her entry into the palace today.

"What? The king of Anlu County wants to come to me often for advice, how can I have time to teach him? Li Xiu suddenly exclaimed when he heard the last, he didn't expect Li Yuan to agree to such a thing! (To be continued.) )
