"Next, if His Highness wants to win people's trust, this thing is the biggest key." Looking at this set of polished crystal pieces, Jiang Tian said slowly: "Of course, if Your Highness wants to extend his life in the future, Second, maybe we still have to fall on this thing.”
"Really?" Prince Li Hong looked at these gadgets with interest and whispered softly: "Gu's illness was contracted when he was young, and then it gets better and worse, changing with the seasons. Even if the father, the emperor, and the queen convene a group of doctors from all over the world, they can't eliminate the root cause, they can only maintain it."
"Of course it's not enough to rely on these things alone. These things are just one of the stepping stones to the many possibilities of the future." Jiang Tian nodded and said: "In fact, these things can't cure any disease, but they can cure many pathological diseases of time. The root cause, pry open a gap."
Later, under the guidance of Jiang Tian, these small parts made of gold and silver were assembled by Prince Li Hong himself; for this reason, he even forgot about his instinctive coughing in his concentration. What finally took shape in Li Hong's hands was a set of optical products based on crystal flakes.
But the first thing that was picked up was a pair of gold-framed glasses. After Prince Li Hong got it in front of his eyes, he put it on his face almost like a self-taught person. He was stunned for a moment, and then showed a strange and joyful expression and said : "Real things become clearer and you can see further."
"These are myopia glasses, and conversely, they are reading glasses." Jiang Tian then introduced: "The former can relieve the pain of all-day paperwork and blurred vision; the latter can be used to reconcile the elderly's eyesight varicose. The disadvantage of not being able to see clearly the things close by is because of stretching.”
"It's so good... it's so good." Prince Li Hong read softly: "I intend to enshrine it in front of the two saints to fulfill my filial piety; and then use this to spread the word and promote it to the world; I think it will alleviate the general officials. The soldiers and the people are tired of filing papers and creating a livelihood for the East Palace!"
"Then this is probably the magnifying glass Li Sheng mentioned?" He picked up another lens with a handle and placed the magnifying glass on a small seal with ease; the magnified details were immediately revealed. "Whether it is rubbing gold inscriptions or researching oracle bones, it is very useful."
Then, he picked up the third item again, a two-section silver tube, and carefully stretched it out. Then, he was seen pointing one eye at the long tube, looking towards the edge of the palace in the distance, and praised again: "It's so close, so lifelike?"
"Has Your Highness ever thought about the use of this thing in future generations?" Jiang Tian took advantage of the situation and gestured with his paws. Prince Li Hong just thought for a moment and replied: "It should be... it is of great use in the marching army formation. It can spy on the enemy's situation, and even predict the enemy's opportunities and strike first?"
"That's right..." Jiang Tian nodded in Pei's arms and said: "If this can be popularized in the army, it can be used as a manpower for many generals, or it can be assigned to vanguards and scouts, then there will be very few people in front of the enemy. It's a secret; if it is used for the offense and defense of the city, it will also be of great benefit."
"Even so!" Prince Li Hong also quickly figured out the stakes, immediately put down the monocular telescope in his hand, and solemnly saluted Jiang Tian with his hands in his hands: "I will save the lives and injuries in those future wars." The soldiers of the Tang Dynasty thank Lisheng for his kindness."
"Actually, it's much more than that?" Jiang Tian waved his paws indifferently: "This thing can not only be used for battlefield reconnaissance, but it can also be used to survey mountains and rivers, geography, and observe astronomy and stars; as long as it is large enough, it can even Even the true appearance of the sun and moon can be glimpsed."
"Please ask Li Sheng to continue teaching orphans..." Upon hearing these words, Prince Li Hong's expression became solemn again: the so-called celestial phenomena of the sun, moon and stars have always been the specialty of Qin Tianjian, and it also involves the destiny and destiny of the past dynasties. Once you can take a peek, it will also be a big shock to the government and the opposition.
"Actually, the evolution of the stars and the deviations in the movement of the sun and the moon have been recorded in the past dynasties." Jiang Tian wrote lightly: "This is not so difficult. After the emergence of astronomical telescopes, as long as there is a suitable opportunity, naturally Someone will discover the secret."
"If your Highness is willing, you can start by observing the moon at night; then you can understand that the so-called place of the lunar calendar does not have the secret place where Chang'e lives in seclusion, nor the Toad Palace where the Jade Rabbit makes medicine, nor the existence of other immortals, only omnipresence. Craters and rings created by eternal meteorites are everywhere.”
"Your Highness will also discover from this that the earth under our feet is not completely flat, but is on a huge sphere; and the vastness of the Tang Dynasty and its surroundings is just one of the celestial spheres in the void of this universe. Above, it’s just a corner. There are countless foreign territories outside the vassal domain.”
"As for the verification of the curved surface of the earth, it is even easier. As long as you send people to the sides of the rivers, lakes and seas, you can see the shadows of masts and sails gradually coming out from the sky... From this, His Highness can launch a great Tang Dynasty The surveying and mapping of territories, and the reconstruction of the calendar.”
"Anyway, a few decades later, there will be a monk named Yi Xing, with the support and sponsorship of the imperial court, re-mapping the geography of the world, revising Li Chunfeng's "Linder Calendar", and re-formulating the "Dayan Calendar". Determined the ecliptic meridian for the first time and created the water-borne armillary sphere.”
"... Of course, after thousands of years, the land and sky within sight can no longer restrain people's footsteps; they can use this to communicate thousands of miles in an instant, and they can also fly across the ocean. , turn the sun and moon into the source of infinity, and make a home on Yinghuo.”
After talking in such a divergent way, Jiang Tian couldn't help but feel thirsty. He drank some water in the tea cup; then he stretched out his paw and pointed at the last assembled product and said: "Of course, if you want to tell your highness, It is beneficial to your body, but it still falls on this thing.”
This simple hand-adjusted optical microscope is slightly more advanced than Leeuwenhoek's original hand-polished microscope in terms of basic principles and craftsmanship; it is more like a children's toy sold on a modern PDD. At this moment, both Pei and Li Hong couldn't help but their eyes lit up.
"Unexpectedly, is this part of the truth about everything in the world?" After a moment, Li Hong, whose world view was obviously greatly affected by the observation of microorganisms in the water, murmured to himself: "It turns out that the water, the air, the inside and outside of the human body are full of microorganisms. These thousands of tiny creatures..."
"You have to understand that this actually has nothing to do with Buddhism's one flower, one leaf, one world, one ladle of water, three thousand nymphs, etc." Jiang Tian interrupted him and said: "This has been true since ancient times until the birth of human beings. Before, at the beginning of the chaos of life’s evolution, many microorganisms already existed.”
"Being a human being is not just a small part of the natural cycle of all things in this world. Therefore, Your Highness only needs to understand that some of these tiny creatures are companions that are beneficial to the human body, such as wine, vinegar, yeast, and some are beneficial to the human body. The root causes of human disorders..."
"For example, bacteria and fungi with a core, and viruses that can reproduce without a core;" At this point, Jiang Tian said to the expectant Crown Prince Li Hong: "Therefore, medical science says that the serious illness that has troubled His Highness for many years is Wind evil entering the lungs is caused by a type of tuberculosis bacteria."
"Of course, the principle of microscopy I gave to His Highness is just a key to the beginning; but as long as His Highness can promote it to the world, let more people participate in research and application, and use the results to widely benefit the public, naturally You will also get feedback and find out the right solution.”
"..." After hearing this, Prince Li Hong couldn't help but close his eyes with a complicated expression, but his heart was filled with indescribable excitement. He didn't know whether it was surprise, relief, or relief. But there are thousands of words on my lips, but there is only one sentence: "I only wish, we will wait and see."
Pei, who witnessed this scene with his own eyes, made some determination on the spot. Although she still doesn't understand the prince's pursuit, as long as there is a glimmer of hope, she will definitely use her life to keep this secret. She also had no doubt about her determination to follow the prince in the future.
"Actually, the future that His Highness wants to pursue is a paradox." Jiang Tian couldn't help but say before leaving: "Although an individual's destiny is nothing compared to the torrent of the times; the more His Highness wants to change, , which also means that the future will become more chaotic and unpredictable.”
"Gu... naturally knows." Prince Li Hong let out a sigh of relief: "But since God intended for Gu to meet Li Sheng, and he also knows what will happen in the future, how can he pretend to be indifferent and muddle along; at least this time Is it Gu’s determination that has changed?”
"No matter what, Gu will do his best to go on, whether it is for Zhirou, for peace, or for the people in the East Palace who follow and respect Gu; even the father and mother of Dongdu..., and Those clan members and ministers who died in the struggle for power and selfish desires."
"In that case, I will wait and see if His Highness can create for me a change that is different enough from that era that I am familiar with." Jiang Tian smiled softly and said: "At least until Your Highness completely loses all fun, I will always accompany you. Watching you, observing and witnessing your end."
For the next two days, Prince Li Hong declined most of his affairs and schedule, and locked himself in his room; except for routine meals, decoctions, and medicinal baths, he almost never showed up; until the third day Three days after his appearance, he summoned Meng Xian to serve as his leader.
At this time, the girl who had been with Youxian Palace for six full days was finally able to return to her residence in the Tangyuan. However, when she faced Jiang Tian, she couldn't help but feel uneasy: "Mr. Li Nu, I... I think she is so pitiful, so I... am willing to be punished."
"What's the use of punishing you for this matter?" Jiang Tian shook his head and said: "I have already understood this matter. It was not something you took the initiative to cause trouble; I asked you to stay away from her in the first place just to avoid any trouble. , but now that we have encountered it, there is no need to deliberately escape."
