Walking out of the newspaper office, it was close to noon at this time, the sun was extremely strong, the sun hung in the sky like a fireball, and there seemed to be a layer of heat wave steaming and distorting on the hot sun-soaked street.

Chen Xu got into the carriage and took out a huge pair of wooden-framed sunglasses from his pocket, Yu Wuya also brought sunglasses from the reception room of the newspaper hall and followed, and a group of guards turned over and got on the horse to escort Chen Xu's carriage.

"Master Hou, should you go to the Hou Mansion or go out of the city and go back to the other courtyard!" The coachman asked.

Chen Xu estimated that Shui Qingrou had already invited the fifth princess out of the city at this time, so he said: "It's hot at noon, let's go to the Hou Mansion to rest first, wait for the afternoon to be cooler and then go out of the city, and go to the Academy of Sciences by the way, I still have something!" ”

"Driving~" The coachman shook the reins, the whip snapped in the air, and four horses domesticated by the Xiongnu from Henan pulled the carriage to the Academy of Sciences.

When he arrived at the Academy of Sciences, he found that it was unusually quiet, Chen Xu inquired, only to know that Zhang Cang couldn't wait to take a large group of people to the river to survey the location of the bridge, and almost half of the people in the entire Academy of Sciences left, leaving only some helpers and clerks, but fortunately, in the glass research room, Tang Ting continued to brave the high temperature to develop glass.

The temperature of the room was very high, Chen Xu felt like a crab thrown into a hot soup pot, there was a feeling that it was about to be cooked, and he couldn't breathe in less than half a minute, so he called Tang Ting to the door and told him about making reading glasses, and also roughly explained the principle, let him use the best materials to pour a few pairs of lenses and let people polish and polish them clearly, and after explaining, he quickly escaped.

These ancient people are not human beings, their bodies are as strong as Wolverine, such a hot day, they can work for a long time in an environment of more than 40 degrees in a continuous manner, and it is also a long time, not only Tang Ting, but also the temperature at noon at this time is more than 30 degrees, Zhang Cang, a scribe, also took hundreds of people to the river to survey, as well as the people who smelted steel, made weapons, burned cement and even built a mausoleum for the emperor, all of them worked in this terrible environment day after day, and there was no interruption throughout the summer.

The principle of reading glasses is a convex lens, but to make qualified reading glasses, you have to measure the interpupillary distance and focusing distance, so as to ensure that you can see clearly at close range and not have soreness in the eyes for a long time, but in this era Chen Xu is impossible to know, so he can only let Tang Ting make more lenses, record the thickness and size of the lens, and send them to An Yuliang to wear for testing when the time comes, to see which one is more suitable, if successful, You can also find some people who are more interested in optics to join the glass research institute to conduct more research on lenses, but at the moment, Chen Xu's main focus is still on making glass.

Because there is no high-purity crystal or silicate material, there will be more or less bubbles in the melted and poured glass, and it is definitely not possible to use it to make high-demand optical equipment such as lenses and magnifying glasses, so Chen Xu has not planned to gather more craftsmen for the glass research institute.

And there is one of the most important reasons is that the hundred schools of thought of the Great Qin Dynasty are prosperous and prosperous, and all kinds of ideas are very rich, but there are very few theories about pure physical science, and only the Mohists have dabbled in optics among the hundreds of Zhuzi, Mozi has studied the characteristics of light propagation along a straight line, and has also verified the principle of small hole imaging, and has also studied the reflection imaging principle of plane mirrors, convex mirrors and concave mirrors, but the Mohists are now almost gone, and they can't find it, and legend has it that Mozi's disciples wrote a book of "The Book of Ink", But Chen Xu asked many people, and they all shook their heads and said that they didn't know that this book existed.

Later, Chen Xu also figured it out, even if this Book of Ink really exists, does it know more than those who have read more than ten years of books and been scientifically educated in his later generations, definitely not, because the primary school students of later generations know the working principle of convex lenses and concave lenses, know that this is the refraction of light in the glass medium, and also know that the speed of light is 300,000 kilometers per second, light is also divided into visible light and invisible light, light has wave-particle duality and other basic theories about light, that is to say, In later generations, any elementary school student who traveled to the Qin Dynasty could casually say these profound theories, and if someone believed it, they could study and prove it, until someone calculated the speed of light countless years later, and finally knew that the child was a great prophet, and then guessed whether he had traveled through the past.

The study of optics is not Chen Xu's theme now, his task is to give priority to the development of people's livelihood science and technology, so the biggest role of the glass research institute is to satisfy his own desires, such as making mirrors for his wife, making jewelry, making window glass, and so on.

Since the annex outside the city was repaired, Chen Xu rarely came to the Qinghe Marquis Mansion.

The main thing is that the weather is too hot, you can bathe in the swimming pool outside the city, and you can also use a large amount of saltpeter ice to cool down without being discovered by others.

Moreover, the territory of the reward is too large, and he also needs to plan the planting structure of his fief in the coming year.

There is a Qinghe hotel, the daily consumption of tea oil, sauce vinegar, onion, ginger, garlic, mustard pepper and other condiments are not a small number, he plans to arrange these commonly used ingredients to arrange people to plant some, there is some can be planted in the hilly area of the hillside of the camellia tree, and so on a few years you can use the camellia fruit to squeeze oil, now all the camellia oil depends on the collection of wild tea tree fruit, the quantity is small and the quality is not high, not to mention the oil yield is relatively low, if the camellia planting can be cultivated as an oil cash crop and promoted, Ordinary people will have another means of making money, and they can earn some money to subsidize their families.

What's more, Chen Xu also arranged for people to buy different melons, fruits and grains from all over the country in the merchants who traveled from south to north, as a foodie, as a world-famous foodie, how could he do if he didn't eat rich things at home.

For example, ice powder, in fact, add some watermelon, strawberry, melon, pineapple and other diced fruit pulp to make assorted ice powder is delicious.

"Hiss~" Sitting on the rickety carriage, Chen Xu had a bowl of colorful pulp and diced ice powder floating in front of him, and then Ha Lazi involuntarily dripped down, and Yu Wuya, who was following him, swallowed a mouthful of saliva.

"What delicacy did Eun Gong think of again?" Yu Wuya asked with a saliva wipe.

Alas! Chen Xu shook his head and didn't want to speak.

At this time, the watermelon is still in the Western Regions, the pineapple is still in Hainan, and the strawberry is estimated to be only a wild variety in the south, which is the season of transplanting seedlings, Chen Xu has eaten a lot when he was a child, but he has not found it in Nanyang and Xianyang, the melon is there, but it is not improved, the taste is not very good and the size is very small, only the size of a fist, but Chen Xu decided to get a few small melons to make a melon ice powder after going back today.

At present, there are only about 200 people left in the Qinghe Hou Mansion, and the housekeeper is still left in the Qinghe Hou Mansion to take care of it, because the edicts of the imperial court and the greetings that come to visit are generally sent to the Hou Mansion, so they need to be properly handled.

Most of the personal maids, guards and domestic servants followed them to the outside of the city, and the two giant pandas and monkeys also moved to the outside of the city, and the panda park is directly a small bamboo forest, and there is a pond inside, and the environment is much better than in the city.

The steward also set up two sets of teams, one to take care of the Hou Mansion and the other to take care of the other courtyard, so the current Qinghe Hou Mansion is much cleaner than in the past, and I can't hear the shouting of the two little girls, and I can't hear the laughter of the people in the house teasing the panda, which seems very silent.

After returning to the Hou Mansion, under the service of the maid, he washed his face and washed his hands and changed into a T-shirt and shorts, and after eating a little food, Chen Xu lay on the bamboo bed and prepared to rest, the two little maids sat next to him and fanned him.

Chen Xu got up depressed and was about to go out to greet him, but Li Xin had already run in by himself, wearing a gorgeous brocade suit, sweat rolling down his forehead, and rushed up to give Chen Xu a bear hug when he entered the door, and then held Chen Xu's hand and shook it vigorously, and the gratitude on his face was overflowing.

"Thank you Qinghehou, I can't get off the bed today after my mother-in-law and more than a dozen concubines last night......"

Chen Xu: ......

The two little maids blushed and covered their mouths, looking at Chen Xu together with grievances.

"Di Daohou, you make it clear, when am I going to your mother-in-law?" Chen Xu was stunned for a while, jumped up and pointed at Li Xin's nose and shouted.

This is completely insulting to his own personality, except for Lao Tzu, who slept with his wife and gentle, other women have never touched it, not to mention that they slept in the Qinghe courtyard with their wives in their arms last night, how could they go to the city to sleep with Li Xin's wife and more than a dozen concubines......

"Forgive the sin, forgive the sin, the letter is too excited to say bad, the Qinghe Marquis gave me yesterday is simply a fairy elixir, the letter only drank a bottle last night, and it really regained its majesty and was like a dragon and tiger, carrying a gun and fighting with the lady and concubine all night, how can it be a cool ......word" Li Xin came to his senses and quickly explained.

That's right, isn't that right? If this headless sentence spreads out, he will definitely be spread as a *** female fairy disciple, and men all over the world will not manage their mother-in-law tightly, and women will be easy to go wherever they go in the future, and they will not be able to see it until they are eight years old and eighty.

Chen Xu arranged for the two maids to make tea with a dark face, and after inviting Li Xin to sit down, he said: "It seems that yesterday's diagnosis was still correct, Di Daohou himself has no physical problems, mainly due to lack of energy, since this medicine can take effect, I am relieved, but yesterday's words are very clear, that the potion is not only difficult to configure, but also highly toxic, remember not to overdose, if you don't need to take the medicine today and the wind is still strong, then don't take the medicine for the time being!" ”

"Yes, Qinghe Hou rest assured, the letter must obey your orders, although the letter is not long, but I have also found a lot of doctors and taken a lot of medicines, but they are not used, or your immortal medicine has an effect, not only the medicine is eliminated, the letter also feels a hundred times brave, but unfortunately it can't be taken often, otherwise the letter will have to buy more than ten concubines to meet the ......"

Li Xin was very excited, sitting on the chair as if his body was still shrugging involuntarily, it seemed that the sequelae of piling at night had not passed, and his body was still in a state of memory movement.

Chen Xu's face was three points darker, but he felt that Li Xin was indeed more powerful, and he had also drunk the beef bone soup potion for three or four days, although he was also relatively brave, and the tossing for more than an hour every day did not make the water gently unable to get out of bed.

But it's reasonable to think about it, Shui Qingrou is not only young, but also a disciple of Liezi who cultivates authentic Taoist kung fu, with strong martial arts, and his physical fitness is not comparable to ordinary women.

Let alone...... Most of this must be Li Xin's bragging.

Thinking of this, Chen Xu was also relieved, and waited for the little maid to bring herbal tea, and after drinking a cup with Li Xin, Li Xin gave Chen Xu the land deed and the house deed he brought, and Chen Xu accepted it after a few words.
