Palace.

After the briefing, Cheng Biting Jin and the three of them met His Majesty together, and Lao Cheng Xianbao said, "Your Majesty, the minister got a treasure." ”

"Zhijie, but what kind of blade did you find?"

Lao Cheng's babbling temperament, Li Shimin was also used to it, so he didn't care too much, and asked casually.

In his mind, it is nothing more than swords, swords and other blades, and if he sees a lot, there is nothing new about it, there are countless in the royal treasury, and he has to send someone to maintain it, otherwise I am afraid that they will all be rusty.

Seeing that Li Shimin was not at ease, Cheng Yanjin said seriously: "Your Majesty, this time it is not a blade, it is a treasure newly invented by Fang Boy." ”

"Oh?"

Fang Yiai's body has been branded, "Fang Yiai's products, must be a high-quality product", this time Li Shimin was interested, raised his eyelids, and looked at it seriously.

"What?"

Cheng Yanjin cautiously took out the telescope from his arms, and offered it like a baby, "This is it—the telescope." ”

Fang Yiai never thought that Lao Cheng, a rough man, could be so careful, I'm afraid he has never been so careful with his own son.

Thinking of this, he turned his head and glanced at Cheng Chumo, silently feeling sad for Cheng Chumo, feeling that it was Lao Cheng's own son.

Sensing Fang Yiai's gaze, Cheng Chumo replied with an inexplicable look and asked him what he meant? Fang Yiai patted him on the shoulder as a sign of comfort.

Ahead, the topic of the two bigwigs continues......

Seeing Lao Cheng's attitude, Li Shimin's expression was also a little serious, he knew that Cheng was biting gold, and his attitude was not an ordinary thing.

He was also pondering in his heart.

The name sounds novel, but it's not surprising, Fang Yi loves newly invented things, and he always makes something weird. "Telescopes?"

"But...... Can you see things in the distance? ”

Li Shimin's eyes lit up and he guessed excitedly.

"Hehe, Your Majesty is really discerning, I didn't expect it at the time, it was Fang Boy who pointed it out." Lao Cheng smiled and offered his fart.

Confirming his thoughts, Li Shimin was excited, and also showed a vigorous and resolute side, immediately picked up the telescope and went to the city tower.

On the castle tower.

Looking down on the entire Chang'an City, it's not spectacular.

"How do you use this thing?"

Li Shimin was afraid of foreign appearances, so he didn't try it indiscriminately, and asked Cheng Yanjin. Lao Cheng naturally knew everything, and personally went up to teach Li Shimin, "Your Majesty closes one eye first, if it doesn't work, you can cover ...... with your hands"

Hearing this, Li Shimin immediately closed his eyes, Lao Cheng didn't talk nonsense anymore, and was depressed in his heart: "Why is it so easy for others!" ”

Of course, he didn't stop, and then said, "Keep your eyes on the small one, and look carefully at the scene in the mirror." ”

Li Shimin did as he said, and then he was shocked, his eyes emitted a strange light, and he stared at the eyepiece tightly, as if he had a panoramic view of the entire Chang'an City, and his heart was surging.

"Good, good! This telescope really lives up to its name, and it can be seen thousands of miles away, haha......" Li Shimin stroked his palms and laughed, very satisfied with these telescopes.

Then, he looked at Fang Yiai again, "God bless my Tang Dynasty, give birth to a character like you, with this thing in hand, my Tang Army is invincible." ”

Fang Yiai had a modest expression on his face and said, "Your Majesty has praised it!" The minister is just for the Tang Dynasty, making some meager efforts. ”

"Good! What a child's heart! ”

Li Shimin was relieved and very satisfied with Fang Yiai's answer, and then talked about the matter, "Can this thing be mass-produced?" ”

"Yes! Zhuang Shang Qingque looked at it, and it is being vigorously built, and it is expected that a batch will be created before the ugly cow goes out, and the middle and high-level military will be installed. Fang Yiai nodded and said.

However, as Fang Yiai said, during the time he got married, he produced a lot of lenses, and the polishing technology has long been completed, and the lenses have been polished, and they only need to be debugged and assembled.

"Great goodness!"

Li Shimin was happy, only to hear Fang Yiai continue, "Your Majesty, this group of ministers can provide it for free, but in the future, the telescope will have to be paid by the court, and the ministers can't keep losing money." ”

"Don't worry, the court can't treat you badly."

This is indeed this problem, Li Shimin agreed with his mouth, and then looked at him suspiciously, and asked, "How much do you want to sell this thing?" ”

"Let's just run through it......"

"What?"

Li Shimin felt that his ears had heard it wrong, and he scolded him. Fang Yiai looked aggrieved and explained: "Your Majesty, this lens tube is made of brass......"

"I don't think it will take half the money."

"There are also two glass mirrors on it......" Fang Yiai continued.

Before he could finish speaking, Li Shimin kicked over, "This glass is burned with sand, it can be worth a few dollars!" How dare you ask for two runs! ”

Since the negligence of the lime, Li Shimin has been paying attention to all the movements of the miscellaneous courtyard, although he does not know the detailed steps, the general direction is still understood.

Fang Yiai gritted his teeth and said with a painful face: "That's consistent!" ”

"Half money! Not a single point more! ”

Lao Li didn't look at his expression, he directly bargained in half, with a threatening meaning in his eyes. Fang Yi's love wanted to make money, so he could only compromise and nodded, "Okay, the minister earns a little hard-earned money." ”

……

A few days later.

It's the day when Cheng Chumo goes on the expedition.

He had binoculars hanging from his chest, which were packed in a leather tube to protect the lenses.

The last time, Li Shiming took it for granted, and the one on Cheng Chumo's body was a newly made batch. Zhang Daliang, the governor of Liangzhou, also had one hanging on his chest, all of which belonged to the same batch.

Yes, Cheng Chumo served as the captain of Liangzhou, and his boss was the one who was in charge of all military affairs, and Zhang Daliang, the governor of Liangzhou.

The soldiers around Cheng Chumo are all retainers of the Cheng family, who followed Lao Cheng to fight on the battlefield, and they are loyal to the Cheng family, and they will definitely repay him thoughtfully. There is also Zhang Daliang's light, and it is unlikely that something will happen.

But, even so, Cheng's mother Cui's eyes were red and swollen, but he didn't cry in front of people, which was unlucky.

The mother of the child is worried, after all, Cheng Chumo is on the battlefield......

Cheng Yanjin is very supportive, the disciples of the generals, who are not fighting with their lives, if they want to make meritorious contributions, they will be killed on the battlefield, this is their fate.

Lao Cheng's arrangement still has a deep meaning.

Now that the Turks have been wiped out, the biggest enemies of the Tang Dynasty are Tuyuhun and Goryeo, Tuyuhun has been invading the border all year round, and the imperial court will sooner or later clean him up, and there will be more opportunities.

Since the last incident, Cheng Chumo's heart was stimulated, and it happened that Li Daliang was appointed as the governor of Liangzhou, and Lao Cheng immediately arranged for him to follow Li Daliang to Liangzhou.

Now Cheng Biting Jin's generation has become famous, and they have begun to consider cultivating the next generation to ensure the longevity of this family business.

Therefore, Cheng Chumo went out this time to gain a future for himself and a future for Cheng Jiabo.
