During the Han Dynasty, especially in the Western Han Dynasty, Shanglin Yuan undertook many different functions.

For the emperor and the princes, it is not only a park for the emperor and the royal family to visit for leisure, but also a royal zoo of the Western Han Dynasty, and also a royal hunting ground for the Western Han Dynasty.

For Shaofu, Shanglinyuan was a farm that could provide animal meat, and it was also a test field used by agricultural officials in the Western Han Dynasty to experiment with new crops and new farming techniques.

And for the ordinary people who have no place to stand in Guanzhong, Shanglin Yuan is also their last hope. Landless peasants could rent land in the forest garden, and the rent was generally much cheaper than that of the landlords. This is also one of the important means for the emperor to clean up the hearts of the people.

Of course, if you want to rent the land of Zhongshang Lin Yuan, you must be innocent, and if someone in the family breaks the law, there will be no chance to rent the land of Shang Lin Yuan.

Although Liu De is not an emperor, not a queen mother, not an empress, or even a crown prince, he is just one of the emperor's many princes.

But at present, Liu De is really the closest to the throne among Liu Qi's many princes.

Shaofu was an institution of the Western Han Dynasty that served the royal family exclusively, but it also possessed the same human expertise as the Shaofu officials.

Just like Chao Cuo changed his attitude in front of Liu De when he was getting closer and closer to the throne of the prince, Shaofu faced Liu De, even if he had not reached the emperor's will, he had already chosen to bow his head.

Shaofu almost hesitated to kneel and lick Liu De's request to mobilize a small number of craftsmen and workshops and then carve out a piece of land in Shanglin Yuan.

And the five hundred gold that Liu De promised Liu Jian was soon delivered to Liu Jian.

The five hundred gold of the Western Han Dynasty is not five hundred taels of gold but five hundred catties of gold, although this is a Han catty.

One catty in the Han system is equal to sixteen taels, and one tael is about fifteen to sixteen grams. The weight of a catty is about 250 grams, which is equivalent to half a catty and a quarter of a kilogram in later generations. Even considering the lack of gold content, it has a value of more than 20 million when converted into RMB.

Looking at the nearly one hundred and twenty-five kilograms of gold delivered to him neatly stacked in front of him, Liu Jian had the urge to embezzle the five hundred gold and bring the gifts he had received these days, and then flash back to the modern era to live a corrupt life.

However, considering that he had to work under Liu De for at least four months, Liu Jian could only give up such a tempting idea strategically.

First, the limestone provided by Shaofu is calcined at a high temperature, and then the quicklime after calcination is mixed with alkali to obtain sodium bicarbonate called baking soda, and finally the sodium bicarbonate is mixed with butter, lard and other oils provided by Shaofu for saponification reaction and PLAY.

That's right, the first invention that Liu Jian made after he became a scientific researcher was not a major invention that benefited the country and the people.

It's soap!

God knows how long it has been since Liu Jian took a good shower?

That's right, the water of the Han Dynasty is good.

Is it bad to be pure natural and pollution-free? The water in the small river is so clear that you can see the bottom of the river, and it is almost like mountain spring water when you take a sip of it.

But good water does not mean that its decontamination ability is strong, Liu Jian's skin is a little oily, even if you rub it with a cloth just by washing it, it will still have a little greasy feeling.

What's more, everyone knows that bathing without soap or shower gel is actually difficult to clean, even if you have taken a serious bath, you can still rub a little gray if you rub hard.

It is the product of a mixture of dust on the body and the excrement of the body's natural metabolism and dead skin.

Although Liu Jian has no cleanliness habits, he is really tired of rubbing for half an hour every time he takes a bath.

After getting the soap, the actual product was much better than Liu Jian imagined.

After Liu Jian explained the process and the role of soap, these craftsmen gave full play to their subjective initiative.

The resulting soap is not only beautiful in appearance, but also completely different from the earth-based soaps that Liu Jian has seen before. The soap also has a faint floral scent on it.

If it weren't for the yellowish color, it would be close to the soap of later generations.

Liu Jian first tried to take a beautiful bath by himself, and then sent Liu De some soap with cleaner colors and beautiful patterns and patterns.

Liu Jian wants to shoot Liu De's sycophant, and Liu De also wants to pat his father Liu Qi's sycophant.

Similarly, Liu Jian also needs to shoot Liu Qi's ass.

He believed that after he sent the soap, with Liu De's political consciousness, he would definitely send Liu Qi a copy of the past as soon as possible.

After all, he is the emperor, and in this era I have the power of life and death in the true sense.

If Liu Jian wants to live well in the coming days, it is very important to leave some good images for Liu Qi.

Sure enough, it didn't take long for the Son of Heaven to reward him from Ganquan Palace.

The will to Liu De Liu Jian didn't know what was written, but he also rewarded Liu Jian with ten gold, ten silk horses and 200,000 money.

Silk and 200,000 yuan are nothing, 200,000 yuan is a lot of income in the Western Han Dynasty, and it is not far behind compared with ten gold. But if Liu Jian wants to take it away, the 200,000 yuan can only be sold as copper.

On the contrary, ten gold is worth an extraordinary, about 500,000 yuan when converted into RMB.

Just making a few pieces of soap became half a millionaire Liu Jian was even more excited, not to mention giving all 200,000 yuan to the craftsmen, according to the contribution in the process of making soap, each craftsman received a huge sum of at least 5,000 yuan. The artisan who thought of filtering impurities and adding flower juice to add fragrance was given a maximum of 30,000 dollars.

There is no need to elaborate on the gratitude and chanting of the craftsmen for the Son of Heaven.

After the heavy reward, Liu Jian made new research and development requirements for craftsmen.

Toilet water.

Entering June, the weather in Chang'an is getting hotter and hotter, and there are more and more mosquitoes. It is necessary to make toilet water to improve Liu Jian's own happy life index.

In essence, toilet water is less technical than soap.

The essence of this thing is alcohol mixed with water and floral essential oil, and it can be done by adding some cool and hot Chinese medicine such as mint and yellow lotus, Liu Jian invited an imperial doctor, prescribed a summer heat and detoxification external application formula and handed it to the craftsmen.

However, the toilet water has not yet been made, and the royal road is coming first.

"Mr. Liu, Your Highness has something to discuss." Facing Liu De, Wang Dao said respectfully.

To be honest, before today, Wang Dao was a little unsure of what position this person was in His Highness's mind.

That day, His Highness specially left this one at the end of the summons and chatted for several hours, plus the laughter that came from the temple at that time.

In this way, it is naturally impossible not to pay attention to it.

But then His Highness put this person in a cold place like Shanglin Yuan. That's right, compared to following His Highness to do things, Shanglin Yuan, where Liu De is often missing, is naturally a cold place.

This makes Wang Dao a little incomprehensible.

Until today, such a big thing has happened, and the first thing His Highness did when he knew about it was to ask himself to invite him. From this point, it can be completely seen what kind of status this person has in the mind of His Highness.

This is regarded as a think tank!

Therefore, the attitude of the royal road became more and more respectful.

"Oh good, the prince leads the way." Approaching Wang Dao's side, Liu De said softly: "Does the prince know why His Highness summoned him?" ”

"Temple. How can the mind of the slave be clear. Wang Dao laughed first, and then said in a low voice: "But today, Your Majesty has issued an edict in Ganquan Palace to divide the kings, and all the adult princes have been crowned kings, only His Royal Highness, His Royal Highness Liu Rong and His Royal Highness Liu Fei have not moved. I want to come to His Highness to summon Mr. at this time, it should be for this matter. ”

"Oh." Liu Jian realized that it was for this reason.

"Thank you, Maharaja!"

"Don't dare, don't dare." Wang Dao hurriedly said.

The people of the inner palace are the best at observing words and feelings. Wang Dao found that he couldn't see the slightest contempt and contempt for himself from Liu Jianjian, and he became more and more determined to get close to Liu Jian.

It must be known that in this era, after Zhao Gao's chaotic government, it was politically correct to despise the eunuchs who were guarded, and Sima Qian regarded the palace punishment as a great shame and shame to see people. In the Han Dynasty, it was more difficult to find a scholar who did not despise and despise eunuchs in his heart than a three-legged toad.

Liu Jian came from later generations, and naturally did not have the contempt and contempt for eunuchs and precautions of the scholars of this era.
