Ministry of Industry

Li Hongtian looked at the things in his hand and nodded. Although www.biquge.info astronomical scope requires a lot of principles to make, as long as you have accessories and know the general principle of focusing. It just so happened that Li Hongtian was also a miscellaneous scholar before, and although he was not very proficient in this point, he still had basic principles.

I personally assembled this bronze mirror, adjusted the distance and kept looking, and finally nodded. Li Hongtian said to the waiter of the Ministry of Industry with satisfaction: "It's very good, go back and make fifty sets of crystal lenses, and make fifty copper tubes like this." ”

Hmm? Do you only have copper pipes and crystal chips? Do you not need accessories? Thinking about it this way, the squire of the Ministry of Works was afraid that he would be punished for doing less, so he asked: "Your Highness, do you want to ask, do you want those spare parts?"

"Well, just make lenses and brass tubes. But remember, the lens and the copper tube are matched in size, and the diameter is two fingers. ”

Hearing this, the waiter of the Ministry of Works nodded in understanding, and said, "Yes, the minister must strictly supervise it." ”

Li Hongtian left the Ministry of Industry with satisfaction and went to Li Xiuning's mansion.

Princess Binh Duong's Mansion

With the arrival of Li Hongtian, Li Xiuning, the princess of Pingyang, said: "Stinky boy, how can you have time to come to me today? Could it be that the one you said is done?"

After hearing the words for two days, he didn't hide it, nodded, and said to Li Xiuning: "Auntie, I have already made the things." But they still need a good location, so I want to ask them to go to Huashan in Huayin County in three days, and I will prove it to them at the top of the mountain at that time. ”

Li Xiuning heard this, although she was a little surprised, she still nodded and said: "No problem, these are all small things, as long as you can really do it, my aunt will have an excuse to attack Du Yan and their family." ”

Hearing this, Li Hongtian smiled, nodded with satisfaction, and said, "This is inevitable. If he didn't involve his cousin, it would be fine, but since he dared to bully my family Mingyue, then he would have to pay the price. ”

Li Xiuning shook his head and said with a smile: "You, it's rare to see that cousin." It's a blessing for this girl to meet such an infatuated child like you. ”

Li Hongtian shook his head disapprovingly, and said, "My nephew thinks it's not like that. On the contrary, it is the nephew who feels that it is the nephew who is blessed. The bright moon is one of my most precious treasures. With her, the nephew's life is complete,"

Li Xiuning did not entangle with Li Hongtian on this issue, but changed the topic and said: "It is not impossible to go to Huashan in Huayin County in three days, but there are two things that you have considered? One is everyone's safety. Since you said Huashan, then we must need to go up the mountain. It's just that the danger of Huashan is very climbable, so how can we go up? The second is that it is the rainy season recently, and rainy days are common. If it rains, I won't allow people to go up the mountain. Whether it will have an impact on your proof when the time comes. ”

Li Hongtian was stunned when he heard this, obviously he ignored this problem. Looking at the sky today, it is still quite clear, and I don't know what will happen in three days. After all, in this day and age, there is no weather forecast. And even if there is a weather forecast, it may not be accurate. After thinking about it, Li Hongtian said: "The days are still the same, although there will be an impact, but this is helpless, at most, we should go green, play for two days and wait for the sky to be clear, it is not too late to verify." ”

Hearing this, Li Xiuning also seemed to understand that his nephew's verification was quite limited. But she still unconditionally supported her nephew and said, "You, you're just so unreliable." Okay, my aunt will do this, and three days later, we will collectively set off in Chang'an and go to Huayin. Speaking of this, Li Xiuning paused and continued: "However, since the stinky boy is here, let's make a delicious meal for my aunt before leaving." It's not in vain that my aunt is helping you, isn't it?"

Hearing this, Li Hongtian sweated profusely, but did not refute, but shook his head helplessly, and said, "My aunt is really becoming more and more like a foodie." Well, it's me who did it myself, and I'm the one who raised you to be a foodie. ”

Hearing this, Li Xiuning laughed, but said sarcastically: "Who do you blame for this, who made you think about eating in your head, and brought us to spoil." ”

At noon, Li Hongtian personally cooked, and when he was eating, he still didn't see the cheap uncle, Chai Shao. Li Hongtian was very curious about this, but this was Li Xiuning's family affair after all, and Li Hongtian was not easy to ask too much. Just knocked on the side and said, "Doesn't my uncle eat together?"

Li Xiuling's expression changed slightly when she heard this, and she said with a little unhappiness: "Stinky boy, don't mention him if you have nothing to do in the future." ”

Hearing this, although Li Hongtian didn't know what was going on between Erlin, he also knew that there was no harmony between the two. nodded, stopped talking, and began to concentrate on destroying the food in front of him, while occasionally talking to Li Xiuning.

Li Xiuning seems to have long been accustomed to being asked about Chai Shao, and he replied just after being angry. Looking at the appearance of enjoying the food, it doesn't look like it's angry, and it doesn't seem to affect your appetite.

Although my aunt is fine, this still reminds Li Hongtian that in the future, this sensitive issue must not be mentioned during dinner. If you don't even have the appetite to eat, then it's a great sin.

The three days came soon, and on this day, most of the talented and beautiful people in Chang'an City gathered outside the Suzaku Gate in Chang'an City. Most of them were people who had participated in the Huixian Yaxu, and were later notified by Princess Pingyang to come to witness it. There are also some people who have heard about the things and come to see them, and they didn't believe what Li Hongtian said about the sky being round and the earth being square. But hearing the reasons that Li Hongtian once said, these people also became suspicious. For this kind of moment, which is likely to be recorded in the history books for people to admire. They don't want to miss it either. Not only them, but even the historians came.

The horse at the front is the forbidden army, because there are so many talented and beautiful people, so Li Hongtian transferred five hundred forbidden troops to defend it. Otherwise, if you really encounter a bold person who comes to rob the Dao, then this group of people will fall except for a few people.

Li Hongtian took Zhou Mingyue and Li Xiuning to sit together. At this time, the weather has warmed up, just in time for hiking, and today's weather looks pretty good. White clouds, blue sky.

Li Xiuning sat in the carriage and looked at the copper pipe with great nature, and said, "Is this what Hongtian said? It seems that it is the first time I have seen it." How does this work?"

Seeing that Li Xiuning was having fun, Li Hongtian said: "You can't use this here." This is a mirror used to look beyond the sky. ”
