In the county test, the government test, and the road test, Wang Ce passed the test easily, but unfortunately he was still a little far from the head of the case, and his score in the road test was sixty-seventh.

With Wang Ce's current level, even if he returns to Guizhou to participate in the township examination, there is almost no chance of being admitted to the examination.

However, there is still some hope for staying in Beijing, because there are very many admission places in Shuntianfu, and the strength of candidates is far inferior to Jiangnan!

But if Wang Ce wanted to take the exam in Shuntianfu, Wang Yuan would have to move over. This practice is easy to attract criticism, Yang Shen's lifting is to return to his hometown to take the exam, Wang Yangming's lifting is also to return to his hometown to take the exam, only shameless and shameless people will choose to move for their son's exam - which involves filial piety, and migration is suspected of betraying the ancestors.

May.

Summoned by the Emperor.

Zhu Houzhao handed over a transparent object and said with a smile: "Erlang, look, what is this?" ”

"Crystals?" Wang Yuan wondered.

Zhu Houzhao shook his head: "No." ”

"Clear glass?" Wang Yuan suddenly couldn't sit still.

Yanshenzhen was the largest production base of medicinal jade in the Ming Dynasty, that is, the manufacture of various colorful glasses.

In the year when Wang Yuan made the clairvoyant mirror, Zhu Houzhao ordered Yan Shenzhen craftsmen to develop transparent glass. It has been 13 years since then, and although some results have been made, the transparency is relatively low. Today's telescopes used in astronomy, military and navigation are still mainly polished crystal. It is also used to watch the clairing mirror of the ball game, or to play with it, it is made of glass.

Wang Yuan couldn't help, even if he did it, he would just add things to try his luck.

"How is it made?" Wang Yuan asked.

Zhu Houzhao pointed to the craftsman kneeling next to him: "You come and say." ”

The craftsman said, "When making glass, add 'nameless' to make it transparent, and the grass people also happened to find it." ”

Anonymous, Chinese herbal medicine, also known as soil, baldness, iron sand, is the main ingredient of gold sore medicine. It can also be used in cooking, and when boiling crabs, it can remove fishy smells. It is also used to refine tung oil, which can collect water and gas. It is also used to cut the wick, and it will break when it touches the wick. When firing pottery, it can also be used to mix and color.

Anyway, it's a natural ore that has a lot of uses.

Its scientific name in later generations is called pyrolite, and the main component is manganese dioxide!

There is nowhere to find the iron shoes, and it takes no effort to get it, who would have thought that refining transparent glass would have to add Chinese medicinal materials to it?

Last time steelmaking, the crucible used a thrush stone.

It seems that in the future, if you can't make progress in your inventions, you will be able to put Chinese medicinal materials and cosmetics indiscriminately, and maybe you will get some miracle results.

Wang Yuan immediately placed an order and paid for the glass, and the craftsmen of Yan Shenzhen quickly got busy.

Microscopes, someone did it, but quickly gave up.

The disciples of the Faculty of Physics, who play with lenses, like to look up at the starry sky, and don't seem to have much interest in the microscopic world.

The lenses of a polished microscope are finer than those of a polished telescope. After countless failures by the craftsmen at home, Wang Yuan finally made a 60x microscope, which can observe fungi clearly, and some large bacteria can also be seen. But if you want to observe small puddings such as E. coli, the performance of the microscope has to be improved.

"Husband, what are you messing with?" Huang E came over and asked.

Wang Yuan smiled: "Observe the little things, come and see for yourself." ”

Under Wang Yuan's teaching, Huang E began to observe yeast. Unfortunately, the microscope magnification is too low, and you can only see dense small particles, and there is nothing to appreciate at all, and those bacteria can't even feel that they are swimming.

It is estimated that this is the reason why the students of the physics school are not interested in the microscopic world - there are not two or three hundred times the microscope, and they can't see that those "little bugs" are living creatures!

I have to keep polishing it.

Wang Yuan said: "Ah Mei, I'll give you a task. ”

Huang E asked, "What task?" ”

Wang Yuan said: "You also understand the principle of lenses, and urge craftsmen to polish finer glass lenses, magnify the power hundreds of times to observe small things." ”

"What's the little thing?" Huang E was puzzled.

Wang Yuan said: "The Buddha views a bowl of water and 48,000 insects. I just wanted to see if there were really 48,000 insects. ”

Huang E couldn't cry or laugh: "You are really bored, you are looking for these pleasures." ”

Wang Yuan Zhengse said: "Looking at the moon with a clairvoyant mirror, you can see that the moon is a potted ball. If you look at the water with a microscope, why can't you see that there are 48,000 insects? If not, it only means that our microscope power is not enough. ”

Huang E pondered silently and nodded for a long time: "Husband is right!" ”

As a result, Huang E didn't write much poetry and lyrics, and no longer voted for "School of Physics", and began to tinker with the microscope at home all day long.

Since the transparent glass was made, Wang Yuan thought about making a glass reflector, but he was blind about how to start. He recalls walking through the old mirror and trying to put a layer of tin foil on it, but the effect is not as good as the copper mirror.

Glass mirrors have appeared in Venice, also with tin foil, but with mercury.

This kind of mirror is poisonous, whether it is the maker or the daily user, it will be more or less poisoned. Before the invention of electrolytic silver plating, glass mirrors could only be made with mercury, and the school of physics obviously did not begin to contact electricity.

And let Wang Yuan make a mirror, even if he tried thousands of methods, he would never think of using mercury. Because he knew that mercury was poisonous and would deliberately avoid it, he would never find the right answer.

It was another day of dusk, and Wang Yuan used a hundredfold new microscope to observe all kinds of things indiscriminately.

"Sir, it's time to eat." Qiyun came over to remind.

Tonight, it's my turn to spend the night in the Xiangxiang room, where a meal has already been prepared. Just because Wang Yuan has been soaking in the laboratory and being with Huang E, it is inconvenient for Xiangxiang to be a concubine. Until the sun was about to set, Xiangxiang couldn't help it, so she sent the maid over to urge.

Huang E smiled: "Husband, go, it's time for Su'er to call for dinner." ”

Wang Yuan got up and said to Qiyun, "Let's go." ”

Qiyun is about to turn eighteen years old, with naturally slightly curly brown-black hair, long eyelashes, and dark gray eyes, all over her body showing an exotic style. What's even more rare is that she is so tall, she has grown to five feet seven inches (1.78 meters), and her long legs and slender waist can simply make a man feel fascinated.

"The master is here!" Xiangxiang greeted warmly and pulled Wang Yuan to take a seat.

The youngest son, Wang Ji, is two years old, and because of mixed race, he is a little different from Han children.

When this kid saw Wang Yuan coming, he ran over and hugged his legs, and shouted in a milky voice: "Daddy, hug, hug!" ”

Wang Yuan picked up his son with a smile and asked, "Have you learned to count?" ”

Xiangxiang hurriedly said, "Ji'er, quickly count for Daddy." What is it after that? ”

Wang Ji shouted: "Three! ”

Xiangxiang reminded: "Two. ”

"Hmm." Wang Ji read vaguely.

Xiangxiang smiled: "Count together." ”

Wang Ji said: "One, three, four, five......"

The pronunciation of the word "two" is difficult, and children obviously do not want to pronounce it.

It's not funny, but Wang Yuan laughs out loud.

Qiyun had already taken the two-stringed piano, played and sang by himself, and used singing and dancing to entertain Wang Yuan's meal. She and Xiangxiang are women of different races, and they have no other skills to marry in Beijing, so they can only rely on these means to consolidate their favors, and they are also the most open in bed.

When they were in Liaodong, Xia Chan and Xiangxiang became pregnant one after another, and Wang Yuan took advantage of the situation to take Qiyun into the house.

After eating and drinking, Qiyun served Wang Yuan to take a bath again, and Xiangxiang was entangled by the child and couldn't leave.

This kid wants to sleep with his mother alive or dead, and Xiangxiang can only sing and coax slowly. After the child fell asleep, Xiangxiang quietly came to Qiyun's room and joined in to play a three-person game with a red face.

is the only one who is willing to have a threesome, and Huang E and Song Linger can't wipe their face.

Rubbing his old waist and waking up, Wang Yuan warned himself to be temperate, these two goblins can simply eat people.

After breakfast, Wang Yuan rode to the imperial city and gave the prince a lesson every morning.

After the lecture, Wang Yuan was called by Zhu Houzhao to go to the leopard room, and the emperor said when he met: "Erlang, prepare to go out of Beijing, I am going to recover Daning City!" ”
