Ying Tianfu, in the palace, Zhu Yuanzhang stood up from the dragon chair, he was furious, he couldn't have imagined that someone would attack his guests, Ma Sanbao was assassinated on the way to the palace, Zhu Yuanzhang felt a little guilty, Ma Sanbao was his guest, and his guest was assassinated, which made him, the emperor's face, a little unbearable.

"What a daring thief! Or is it inside the Ming army? Order all the generals to check the internal soldiers, all in Nanjing City immediately report, if there are soldiers who have lost arrow feathers, they must also report! Those who conceal it will be killed! Zhu Yuanzhang was furious and sent an order to all the officers and soldiers, after he heard Zhu Di's story, Long Yan was furious, and his old face was a little unbearable.

The eunuchs present in the court trembled when they heard this, and cold sweat broke out on their backs, His Majesty's angry appearance at this moment was the first time they had seen each other since they entered the palace, and now, His Majesty was angry for a person who had nothing to do with him, in the eyes of the eunuchs, this person was just Zhu Di's protégé, who would have thought that His Majesty would value an eight-year-old child so much.

..........................

The envoy from the Western Regions did not dare to have any words, he looked at the immortal Ma Sanbao's eyes full of admiration, he was the first time he had heard that someone could survive three assassinations, in their Western Regions, there were many kings who died on the spot after only one assassination.

"Don't talk about assassination yet, Messenger, tell me how to make colorless glass." Ma Sanbao said that the moment he spoke the foreign language without a teacher, even the envoy of the Western Regions looked at the eight-year-old child in front of him with some surprise, and the translator had not yet spoken, Ma Sanbao's fluent English made the translation worthless.

Shocked to shocked, the messenger still answered Ma Sanbao's question very obediently, Ma Sanbao successfully set out the production process of colorless glass from the mouth of the messenger, he was assassinated this time, but also strengthened his determination to make glass, he even decided to make a pair of telescopes in addition to making a scope, in the Ming Dynasty, the telescope is not to think about, it is a Western invention. Don't look at the telescope is very ordinary, but it is a great help to observe the opponent on the battlefield, in the Ming Dynasty, you can get the help of the telescope, you can know the supply status of the enemy army early.

Assassination after assassination made Ma Sanbao's idea of self-preservation gradually clear, since the invention of AK, he also can't care about the wrong behavior of speeding up the progress of history, he doesn't want to die in vain, if there is an assassination next time, the telescope can also help him explore the assassin's escape route, with a sniper rifle that is a shot accurate.

"Your Highness, I think there is an empty space that can be used to produce glass." Ma Sanbao found Zhu Di as soon as he got the glass making method from the messenger, and shared his ideas with the four princes, who were his investors, and all the ideas could only be realized by sharing them with Zhu Di.

"What industry are you going to develop after you get glass?" Zhu Di was puzzled, he had no other role than glass, except for making glass balls and windows that were more beautiful.

"Good thing, when the time comes, our army will be invincible, do you want to remotely monitor the enemy's military situation? As long as I am given a certain chance to produce, I can make it for you! Ma Sanbao said that his knowledge blind spots had been filled, and he was even a little amazed by the craftsmanship of the Western Regions.

"No wonder Westerners can always lead the world in science and technology, don't look at the glass is simple, this is the crystallization of wisdom, Daming now uses papier-mâché windows, if there is glass, even if it is beautiful, it can also make the house brighter." Ma Sanbao sighed in his heart, he didn't want to praise the Western Regions in front of Zhu Di, the Ming royal family thought that they were in the Heavenly Empire, and nothing was comparable to the Western Regions.

Listening to Ma Sanbao's narration, Zhu Di was shocked, he had never associated glass with such a process, he Daming disdained the glass production process, for Daming it was just a product of bells and whistles, unexpectedly, listening to Ma Sanbao's narration, glass still has such an effect, which made Zhu Di curious, and immediately told his father Zhu Yuanzhang.

Still in the lobby, Zhu Yuanzhang got the news, the previous anger was gone, and Zhu Di, he was also shocked by Ma Sanbao's narration, he never thought that the glass technology he had always looked down on could be used in such a way, as Ma Sanbao said, placed in the army, the Ming will be invincible in the world, and can observe the opponent's troops in advance, which can make a lot of changes in the battle situation.

As the father of the war madman Zhu Di, Zhu Yuanzhang is also an emperor who likes to fight in the south and the north. Be ahead of the world! Carry forward the telescope in the army! If it happens, I will protect your innocence! ”

Ma Sanbao was overjoyed when he heard this, and hurriedly knelt down and thanked Zhu Yuanzhang. What is he most looking forward to? is to protect his innocence, he doesn't want to enter the palace as a eunuch, follow Zhu Di's side, he is no longer looking for opportunities to test whether Zhu Di can keep his innocence, but Zhu Di has never given him any reply, now, Zhu Yuanzhang personally promised to protect his innocence, which naturally ignited his passion, as long as he can make the telescope, he can keep his innocence, why not?

After being reincarnated as Zheng He's identity, his worries have been dispelled in Ma Sanbao's heart, and his innocence is Ma Sanbao's wish after coming to this world, and he is about to come true, so he naturally has to vigorously complete the telescope.

As soon as Zhu Yuanzhang's holy decree came out, Zhu Di was a little disappointed, he was still counting on using Ma Sanbao's innocent condition to let Ma Sanbao help him more, but he didn't expect his father to take the lead in giving Ma Sanbao a promise, and he couldn't say anything, the identity of a eunuch is an identity that has existed in China since ancient times, and many talented people have become eunuchs after taking refuge in the royal family, Zhu Di also understands Ma Sanbao's thoughts, Ma Sanbao is capable, and the condition for not wanting to become a eunuch is also Zhu Di's bargaining chips for hanging Ma Sanbao, and now the chips are gone, I don't know if Ma Sanbao will be as worried about himself as he was before.

"Fourth Highness, don't worry, I know that you have always used this as a bargaining chip, it's okay, I will still assist you, you have regarded me as a brother before, I, naturally, I regard you as a brother in my heart. Later, let's go back in the carriage, I'm afraid of being assassinated! Ma Sanbao said in Zhu Di's ear, stabilizing Zhu Di's heart, he also understood that if he didn't explain to Zhu Di, Zhu Di would easily have trouble with himself, and he was still waiting to hug Zhu Di's thighs, he had no ambition to be the emperor, and he only hoped that a man of great talent would be able to support a prince.

..................................

Time passed day by day, Ma Sanbao and Zhu Di's industrial park was also successfully established, under Ma Sanbao's arrangement, his own glass factory was also successfully established, the glass factory covers a large area, not much worse than Ma Sanbao and Zhu Di's other industries, this emerging industry even Ma Sanbao is not so confident, he has not done in addition to the experiment to successfully make glass, has not made his long-awaited convex mirror and concave mirror.

The matching of convex mirror and concave mirror has become a problem that Ma Sanbao wants to think about, he has no mold, everything has to start from scratch, even if it is the focus distance, he also knows it by heart, but the mold has not been completed, even if it is a good woman, it is difficult to cook without rice.

For the telescope and sight of this kind of precision instruments, Ma Sanbao is not too sure, he spent many days to make a lot of drawings, looking for a blacksmith to build for fear that the blacksmith will not be completed according to his requirements, specially made a protractor, which does not exist in the Ming Dynasty invention.

With the help of Ma Sanbao, the workers in the industrial park have also become different from the workers in the outside world, and the process provided by Ma Sanbao is completely beyond their understanding and beyond this era, and even the workers in charge of glass manufacturing have been trained for many days before entering the industrial line.

"Young Master Ma, the master asked me to ask you, do these lenses have to be built according to the requirements of the mold?" In the industrial park, there is a very young lady, only two years older than Ma Sanbao, he is Ma Sanbao recruited the glass master when he found a helper, although the young lady is not very old, a pretty face has the outline of a beautiful embryo, within a few years will be a slim girl.

"Sister Qiao'er, tell your master, just build it according to the mold, this time it should be the most accurate mold I designed, and this time it should be able to complete the telescope required by His Majesty!" Ma Sanbao said that he had been in the industrial park for many days in order to make the telescope, and he had already mingled with many masters in the industrial park, and even Zhu Di did not expect that the workers he recruited would be able to skillfully make the products they needed in a short period of time.

"Okay." The little girl smiled at Ma Sanbao, during this time she would chat with Ma Sanbao in her spare time, don't look at Ma Sanbao's young age, in addition to doing crafts, there is still a hand in storytelling, Qiao'er has also become Ma Sanbao's little fan sister in just a few days of contact, whenever Qiao'er's master has some doubts, she will ask Ma Sanbao.

"This time, we must succeed!" As the amount of glass made by the master craftsmen increased, Ma Sanbao piled up a lot of small transparent discs around him, and he was experimenting piece by piece, stuffing the glass pieces into the telescope shell he made.

"It's done, the telescope is done! Sister Qiao'er, do you want to try looking at the telescope? Ma Sanbao was a little excited, reached out and grabbed Qiao'er's little hand beside him, and put Qiao'er's little hand on the telescope hand in hand, so that Qiao'er could see this cross-era handicraft.
