At this time, there were few people who could enter his room, and from the slightly heavy footsteps, Hu Guang had already guessed who it was: "Big brother, is there something wrong with me?" ”

"Well, it's inconvenient to have a lot of people during the day. Second brother, come here and click on the reward that the eldest brother gave you! As he expected, it was Hu Kuan who came.

Hu Guang knew that he couldn't read it, so he put down the book in his hand, put it down and moved it to the side to make room.

Hu Kuan put a relatively large package on the table and untied it, and turned on the oil lamp so that the second brother could count it.

Hu Guang was not interested in these, thinking that it would be perfunctory. But who knows, he glanced at it, and suddenly his heart was happy, and he hurriedly reached over, picked up something, approached the oil lamp and looked at it repeatedly.

"Yes, the color is very pure!" Hu Guang smiled on his face and praised him.

Hu Kuan saw that the second brother liked it, so he smiled on the side and said, "The eldest brother said that he was afraid that you would read so many books and see a problem with your eyes." These two pieces of water essence are for you. ”

In ancient times, people were short-sighted, and they also had glasses. But it's not glass, it's polished with water spirits, which are modern crystals.

Hu Guang took the water spirit, but he thought in his heart that it was not for glasses. At the head of the city yesterday, when he observed the attack of the Ming army, he had already thought that it would be good if he had a telescope.

Now that you have this water spirit, you can polish the lens to make the telescope. There is no doubt about the advantage of the enemy first.

At this point in time in the first year of Chongzhen, the territory of the Ming Dynasty was already expected to have a telescope, but it was brought from Europe by the German Deng Yuhan. In history, an important milestone in the popularization of telescopes in the Ming Dynasty, that is, the book "Telescope" translated by Tang Ruowang and Li Zubai, will not be published until the second year of Chongzhen.

Therefore, in the first year of Chongzhen, basically no one had heard of telescopes, let alone Hu Kuan, who had never read books and had not been to many places.

When Hu Guang briefly explained the function of the telescope, Hu Kuan's eyes were about to bulge, took the two pieces of transparent water essence, and asked Hu Guang with an incredible expression: "This is ...... Can this really make clairvoyance? ”

"Hehe, it's not that exaggerated. The magnification of this kind of optical telescope is not too high, but it is far better than visual inspection. Hu Guang replied with a smile, and at the same time thought in his heart that the astronomical telescope of later generations would not be clairvoyant, but tenlily.

If you tell the eldest brother now that the high-level telescope can see the moon in the sky, there is no Guanghan Palace, no Chang'e and Jade Rabbit, and the eldest brother is likely to be surprised that he can't keep his eyeballs!

Hu Kuan was born in the military, and he didn't collect at night, so he understood the meaning of having a telescope in the war more deeply than ordinary people.

Looking at the second brother's indifferent expression, looking back on his magical performance in the past few days, although Hu Kuan felt incredible, he still chose to believe in his own brother.

He carefully held the two pieces of water essence and solemnly returned them to Hu Guang. After seeing Hu Guang put it away, he asked excitedly: "Second brother, this thousand miles ...... When will the telescope be made? ”

Water spirits are expensive, especially this kind of transparent water spirits, and it is not easy to find them. Hu Guang hadn't polished the lenses himself, and it was estimated that he would spoil the water spirit by doing it himself, so he had to answer truthfully: "Big brother, I'm afraid you have to find a professional skilled craftsman, otherwise I'm afraid I will waste this water essence." ”

When Hu Kuan heard this, he nodded again and again, he paced back and forth in the house for a while, and immediately stopped, turned his head to Hu Guang and said hurriedly: "I'm afraid this craftsman who sharpens water spirits will have to go to Yan'an Mansion to find it, otherwise, I will go to Yan'an Mansion early tomorrow morning and invite the craftsman to ......."

Speaking of this, he suddenly remembered that he was already the leader of a party, and there were so many things here that he couldn't be busy, so how could he go to Yan'an Mansion at this time!

When Hu Guang saw his eldest brother come to his senses and looked at him, the two of them laughed in unison.

He could understand how much the eldest brother, as a person who was born at night, longed for this telescope. Why don't you wait for yourself to be free, and then go to Yan'an Mansion.

He was still thinking about it, but Hu Kuan turned around and walked out of the door, and said as he walked: "Second brother, you wait, I'll ask the eldest brother if he still has this kind of water spirit over there, so as not to lose and make a telescope......

"Big brother, don't ......be in a hurry" Before Hu Guang's words were finished, Hu Kuan had disappeared at the door. Seeing the eldest brother's urgency, he couldn't help but shake his head, quite helpless.

In fact, the telescope is only an auxiliary tool in the end, not a decisive factor in winning the battle. Thinking about it like this, Hu Guang couldn't help but be a little worried, whether it was the eldest brother or Wang Jiayin, the current ability, if you want to command the army and confront the Ming army, I'm afraid it's not so easy!

Courage is there, but the vision, or military literacy, is not yet up to it. Thinking of this, Hu Guang was a little worried.

Don't talk about your own knowledge, even if the vision of ordinary people in later generations is far better than the two of them.

Hu Guang's eyes turned back to the "New Book of Ji Xiao" on the table, it seems that this rebellion cannot be pinned on these people, although history proves that they can eventually overthrow the Ming Dynasty, but too many people died, and in the end the Manchu Qing picked the fruits of victory, which is not what he wants to see.

As soon as he thought of this, Hu Guang suddenly remembered that during the day, he thought that he wanted to teach them Mandarin, Hanyu Pinyin, and Simplified Chinese characters.

Yes, if you spread these things, oh, and other knowledge and ideas of the 21st century, then your position in the rebel army, a position such as a military advisor or a first assistant after the founding of the country, is far from enough. It must be a group of subordinates with high prestige and obedient subordinates like the Founding Emperor!

Thinking like this, Hu Guang suddenly had a general understanding of what he was going to do at the end of the Ming Dynasty for the first time, and how he was going to do it.

Before that, his thoughts were only to change history, not to let the land of China fall, not to let the Manchus steal Kyushu, not to let the white people do whatever they wanted in the Age of Discovery, and to let China continue to lead the world.

Thinking about it, Hu Guang stayed there all by himself. He remembered that in the past few days, he had had conflicted with the thoughts and concepts of these ancient people, many of which he could not compromise. I thought that if I really became the founding emperor, it would bring earth-shaking changes to the world and a new world would appear.

Such a world, such a China, what a glorious existence it will be!

Hu Guang was so enveloped in his imagination that he didn't even know the sound of chaotic footsteps outside.

It wasn't until the door was pushed open with a "bang" that a gust of cold wind blew in, freezing Hu Guang for a while, that he reacted. When I turned my head to look at it, I couldn't help but be dumbfounded.
