The first legitimate son of the Tang Dynasty

Chapter 108 The powerful netizens

"Haha!" Li An looked at the method of making soap recorded in his notebook with a happy expression on his lips. This was the moment when he returned to modern times and was a little happy.

However, Ang Lee was not satisfied yet. He started a bounty topic on a certain call: If he traveled back to the Tang Dynasty, what would be the most technologically advanced thing he could create?
Ang Lee’s bounty score was very high, so he soon received the expert’s answer:

The first master called Tiantian Chiluobo: Back in the Tang Dynasty, it was very simple. If the saddle was not invented, then the saddle was invented. If the stirrup was not invented, then the stirrup was invented. If the horseshoe was not invented, then the horseshoe was invented. Very military value.If it's already been invented, forget it.

By the way, during the Zhenguan period of the Tang Dynasty, the Quyu plow should not have been invented. This can be invented, because the Tang Dynasty's straight-coupled plow required two oxen to be used, while the curved-column plow only needed one ox to be used. It has good productivity. ah.

As soon as Li An saw it, he quickly recorded it, searched for information about Quyuanli on the Internet, and then printed out all the parts of Quyuanli and put them away carefully. It is true that this Quyuanli is a good thing. You must know that Li Shimin is now He attaches great importance to agriculture. If he can present this curved shaft plow, it will definitely attract Li Shimin's attention.

Doudouhua, the second expert: Well, in terms of living direction, you can make briquettes, and the exhaust pipe is also very simple. The key is refractory bricks.

I don't know the formula or process of refractory bricks. I probably only know that materials with different particle sizes are used to bake them. I can only ask the kiln craftsmen to try them.With briquettes and stoves, heating can be started. These can only be used by wealthy people in a short period of time.

Considering the price of firewood in ancient times, maybe honeycomb can be popularized.

If the iron pan has not been invented, you can also invent an iron pan, using rapeseed oil, or soybean oil and lard to stir-fry, which is extravagant.It can improve the level of cooking and improve the level of enjoyment.Tap water, ceramic flush toilets, ceramic showers, and ceramic bathtubs are luxurious but fun to use, as long as you don’t get criticized.

"Ah!" Li An once again wrote quickly about honeycomb briquettes, refractory bricks, iron pots, rapeseed oil, soybean oil, tap water, and flush toilets. Li An carefully recorded them one by one. Once the records were completed, he would investigate how to make these things. , and then record it in a small notebook, these are kept for future use.

"Ding!"

Several more messages came.

The third person had nothing to say: telescope, it doesn’t matter if there is no glass, use white crystal.

Find a craftsman who polishes jade slowly.

The cost is very expensive, but it has great military and astronomical value.In the same way, myopia glasses and reading glasses can also be made.Don't be afraid of the high cost. Tianhuang nobles are not short of that little money.If you have money, you can build a prism to create an artificial rainbow. These few things can simply promote optical enlightenment research.

With the invention of telescopes, myopia glasses, and reading glasses, which are luxury goods with practical value, we can recruit a large number of craftsmen and smart people to use exhaustive methods to research and develop glass. I only know that we need to use white sand, mica, and tin. The float process is used to make flat plates, but I don’t know the temperature or annealing, so I can only try it.

If you are lucky, you can also make a glass mirror. The principle is known, but the formula and process are not known, so you can only try it through exhaustive methods.

Li An did not remember this, because the method of making glass is too troublesome, and glass was still relatively expensive in the Tang Dynasty. Li An may consider buying some glass products in modern times in the future, so that he can maintain The rarity and price of glass. If Ang Lee makes glass on a large scale, it is another matter whether it can be made first. If it is made, it will be troublesome if others see the huge benefits of glass and leak the secret or fight with Ang Lee. .

So glass, telescopes, myopia glasses, reading glasses, etc. Li An would buy them in modern times and bring them back to the Tang Dynasty. This Li An would keep as his trump card, a trump card that can quickly gather money.The fourth one, Xishan Qianguxiu: Hehe. I am studying the nuclear industry. Time travel in our major is actually quite miserable. We only have two functions. First, we can add a small amount of uranium salt to make super bright luminous pearls to send to the bride.

Second, add a large amount of uranium salt to make a cursed ball and give it to the enemy.

This answer made Li Ang laugh, but the curse ball is not unusable, it is a good thing that can harm people.

Of course, Li An doesn't need it now, but if that Tang Shanshi is ungrateful, Li An will not be merciful and give him a cursed ball so that he can die without knowing how he died.

Later, Li An got some good means of time travel. First, he could make distilled wine and prepare disinfectant based on high-purity wine.

Make a steamer to promote the concept of high-temperature steam sterilization.

Promote asepsis on the basis of 1 and 2, and significantly reduce battlefield mortality and women's postpartum mortality.

Promote the concept of battlefield care, and combine battlefield care with 3, which is obviously helpful in maintaining morale.

There are also improved natural rubber to make durable soles and contraceptive tools. This is a bad idea. If Li Shimin knew about it, he would kill you with a knife, because Datang needs people the most right now. Are you making contraceptive tools for him?

Then there were cement, waterwheels, perfume, printing, black powder, fireworks, penicillin, cowpox vaccine, especially penicillin. This shocked Ang Lee. According to the netizen’s answer, he said that as early as the Tang Dynasty, Tailors in Anseong would apply paste with green hair on their fingers cut by scissors to help the wound heal. This is because the substance produced by the green hair has a bactericidal effect, which is why people first used penicillin.

This is the earliest recorded use of penicillin.

But in time travel novels, treatment is often achieved through the production of penicillin. Is this really possible in ancient times?This is possible because the early purification method of penicillin was to directly extract penicillin from the solid culture medium with water and then make it into dry powder.

However, this method can only be produced in small quantities. If produced in large quantities, ancient conditions would cause contamination by other bacteria.

If penicillin can be made, can syringe needles also be made in ancient times?Some historical novels ignore the invention of needles, and some novels think that making needles is too difficult. In fact, making needles is not difficult. Just make a thick needle first and then use the ductility of metal to make it thin. Yes, the principle is the same as the capillary glass tube.

Li An really admired the netizens on the Internet. It seemed that there was nothing they didn't know. Li An was looking for information while reading, and taking notes along the way. He was so busy until about one o'clock in the morning. , I looked and saw that I remembered almost everything.

Li An finally went to bed to rest, and slept until about 9 o'clock the next morning. Just when Li An opened his eyes and was about to get up, a carriage appeared outside Chang'an City in the Tang Dynasty, and Li Shimin was in the carriage. and Queen Changsun sat in it happily.

Today Li Shimin did not go to court, but announced that he would take a rest for a day, and followed Li Shimin and Empress Changsun and couldn't wait to go to Lijiacun.
