Of course, money is not so easy to make. Although the playboys have wasted some extravagance, they are not fools either.

Therefore, the main purpose of Li Muyun recruiting them this time was to get a vaccination first, and let them talk to the elderly at home after they go back, and at the same time, it was revealed in secret that the whole thing was taken care of by a big shot behind it.

The big man, the big man Man Chang'an mentioned by Li Muyun, knew who it was. As the adopted son of the Supreme Emperor Li Yuan, His Majesty the Emperor trusted his brother very much. As long as he did not rebel, he could do whatever he wanted in the Tang Dynasty.

...

Two months ago in Liangzhou, northwest, Cheng Yaojin stood above the city head and looked southwest. A large tent spread to the end of the sky. It was a army that was full of breath.

I don't know what crazy this small country that lived between the Tang Dynasty and the Tubo was going crazy, but actually wanted to take advantage of the Tang Dynasty and sent tens of thousands of troops to Liangzhou. If Lao Cheng and the others had not arrived in time, the Liangzhou City would have been full of misery.

After watching the awning in his hand for a long time, when he couldn't see clearly, Lao Cheng seemed to have thought of something and stretched out his hand to Su Lie beside him: "Get it!"

"What?" Su Lie took two steps back conditionedly.

"Typeg! I won't steal yours, what are you afraid of?" Cheng Yaojinniu glared at him and said carelessly.

On the way to Liangzhou, Su Lie accidentally took out a telescope to observe the terrain and landform during a march, but was seen by Lao Cheng. As a result, the old guy was thinking about the telescope and borrowed it for use if he had any problems.

Su Lie was afraid that Lao Cheng would not return it, so he kept collecting the telescope in person. He could borrow it, but he had to take it himself. He would turn it wherever Lao Cheng wanted to look, and he would never hand it over to Lao Cheng.

This time, it was naturally the same rule. Su Lie reluctantly took out the telescope from his arms and wiped it carefully. He raised his hands and was about to put them in front of Lao Cheng, but he was accidentally snatched by the old man.

"Hey!" Seeing that the telescope was stolen, Su Lie jumped anxiously, but Lao Cheng was so shameless that he ignored him at all. He pointed to the city and said, "Go and go, go down and count the food and grass, and report a correct number to the evening."

What a big deal, did you just count it out yesterday? Su Lie stared at the telescope that fell into Lao Cheng's hand and was crying without tears.

Cheng Yaojin rolled his big eyes and weighed the thing in his hand and said, "You guy is so anxious. The thing was made by your brother-in-law. You can just ask him to make one. It's so stingy."

He took other people's things and said that others were stingy. Although Su Lie knew the temper of Lao Cheng, he was still trembling all over. There was only one telescope in the Tang Dynasty. He had been borrowed from his sister after all. Now, the sheep fell into the tiger's mouth. How could he explain to his sister when he went back?!

However, Lao Cheng ignored Su Lie at this time, held the iron tube and looked at the camp in the distance, muttering while looking: "Well, okay, good thing, you can see clearly. Well, I saw the enemy's handsome flag. Alas, it turned out that the khan was so angry that he didn't come. Oh, they were actually killing cows. It was so cruel!"

Su Lie really couldn't listen anymore, so he turned around and left without seeing each other. This old man was just a bad person, and it was a shame to stand with him.

Looking back, Lao Su felt that he was also proud. You said that there was such an old man around you, and you could just use a telescope to show it out. Now that the thing was taken away by the old man, who would you like to ask for advice? Let me write a letter to tell my sister, remember that she should stop thinking about that thing.

The depressed Old Su wrote a sincere family letter to Su Wanqing with a depressed look, confessing his mistakes and complaining about the shamelessness of Cheng's man.

A month and a half later, before the Mid-Autumn Festival, Lao Su received a receipt from Chang'an - a small box.

Old Su, who was guilty, opened the box with a nervous mood. However, there was no letter in the box, only another box. Old Su continued to open it in wonder, and then it was still the box.

Back and forth, Su Lie opened six boxes in total, and saw a series of "hahaha" on the last box. After he opened the "hahahaha" angrily, an exquisite little cylinder appeared in front of him, and there was a note under the little cylinder: Open it and take a look.

A few days later, Lao Cheng de squeaked all the generals and observed the movements of the enemy on the top of the city. He held up a telescope with a layer of patina that had been rubbed. When he was humming, he was shocked to find that Su Lie beside him also took out something, and saw that the object was only the length of his fingers, made of pure copper, and the light of gold flashed in the sunlight.

Su Lie did not squint his eyes, and twisted his hands gently, then pulled it apart the pure copper object nearly half a foot long, and then raised it in front of him again.

Looking at the high-end, elegant and high-end thing, and then looking at the iron tube in my hand, Lao Cheng felt very low, really low, so he silently put away the telescope that had been grinded out of patina in his hand.

In Chang'an, Li Shimin walked around the study room and finally couldn't help it. He ordered the eunuch Lao Long: "You, go and find that bastard Li Muyun for me, go immediately, go!"

Lao Long agreed and left like a flying one. In less than half an hour, he returned with Li Muyun, who was confused.

"Look at the good things you did!" As soon as he entered the room, before Li Muyun could figure out the situation, Li Er had already thrown a piece of broken paper at his feet, scaring him to tremble.

Could it be that I had done something a few days ago? No, I just am a palace maid, so I shouldn't be so angry, right? Li Muyun lowered his head and picked up the broken paper on the ground. After watching it, he immediately laughed.

Thinking of the battle report sent back from Liangzhou, Li Er felt pain and slapped the table and cursed: "Laugh, you dare to laugh, that's the telescope. My two generals almost fought. Li Muyun, you bastard, tell me how to solve this problem!"

Li Muyun shrank his neck and smacked his lips and said, "Brother, it's just a telescope, it's not a big deal. Just get some more and send them to them."

Li Shimin was so angry that he thought to himself that if I knew what a telescope was, would I have to come to you?!

Fortunately, the eunuch Lao Long saw some tricks when he observed his words and looked at him, and went out to smooth things over and said, "King Xiaoyao, what kind of thing is this telescope? Can you tell us?"

"Oh, that thing is simple, a piece of reading glasses, plus a piece of myopia glasses, find a tube to wrap it up."

Li Muyun explained the principle concisely. This kind of thing is actually just a matter of saying it. Anyway, he didn't expect Li Shimin and the eunuch Lao Long to work hard to get a telescope.

But his explanation still made Li Shimin a little depressed, and he stared at him and said, "What do you mean is that several generals under my command fought for two broken crystals? They were still bruised and swollen?"

Li Muyun touched his nose awkwardly. The telescope was something he made for fun. Who would have thought that Cheng Yao and Su Lie would fight for that thing?

Besides, due to the light transmittance, the quality of telescopes in the Tang Dynasty during this period is incomparable to that of later generations. It is basically not much different from the quality of children's toys. For this thing, it is simply too funny to fight.

Based on this logic, if you use equipment such as infrared telescopes or thermal imagers in later generations, you wouldn’t be able to get the dog’s brain?

Li Muyun secretly laughed at the local tycoons who were thousands of miles away. Thinking that Li Shimin still had to deal with it himself, he had to stoop and said, "Your Majesty, I don't mean that. I actually want to say that the telescope is actually just a small thing, just used to coax children. I also made a trick to coax Wanqing... to make Wanqing happy."

As a result, it was fine if Li Muyun didn't explain. The more he explained, Li Shimin became more angry. At first, he still had two crystal pieces. This one was slightly sticking to cultural technology, and after explaining it, it turned into a toy for children. Cheng Yaojin and Su Lie fought for one toy?

Li Da Killer might also think that this explanation is a bit unfavorable. He scratched his head and thought about it and said, "Uh..., actually, I don't mean that. You know, I'm a stupid person and can't speak..."

Li Er was really unable to bear Li Muyun, so he waved his hand to interrupt him and said, "Okay, okay, shut up your mouth for me and beat me from now on. You just need to tell me if this thing can be made again."

"The way of being able is to be able, but it requires a lot of colorless crystals, that thing..."

Li Shimin didn't want to hear a word of nonsense now. Without waiting for Li Muyun to finish his words, he said directly: "Crystals aren't it? I will mobilize a batch for you, limiting you to three days, and getting fifty pieces."

Li Muyun blinked his eyes, and felt joy and sorrow in his heart. He said to Li Er with a bitter face: "Your Majesty, you misunderstood. This crystal actually needs to be processed. It takes less than half a month to deal with it, so three days is really not enough."

Li Shimin looked at Li Muyun up and down, as if he was sure that his words were true or not, but fortunately, the matter was not so anxious, so he thought for a while and said, "Then it will take half a month. If you can't see fifty telescopes in half a month, I will discount your legs."

Li Muyun nodded quickly: "As long as you go, no problem, but you have to match this man, right?"

Li Shimin hummed and said, "You need someone to arrange it yourself. I will give you a handwritten order."
