Chapter 807
After Jiang Yuheng left, Xiaoer went to teach Ma Shi how to make rose tea.

Not just rose tea, but rose essential oil!
After Shangguan Xuanyi got back the distillation tools, she was going to teach Ma Shi how to distill rose essential oil.

Rose essential oil is called "the queen of essential oils", but only two thousand catties of roses can extract about one catty of rose essential oil, and ten catties of rose petals can only produce one drop of rose essential oil, so rose essential oil can be said to be the most expensive essential oil in the world , more expensive than gold.

But expensive is also valuable. Rose essential oil is very beneficial to women: it can lighten spots, whiten skin, improve dry skin, and restore skin elasticity. It is the most suitable essential oil for women's health care.

The best time to extract essential oils is within 24 hours after the roses are picked. The roses that Xiaoer bought from Boss Feng have already passed the optimal extraction time, so she used them for Ma Shi to practice.

Xiao'er runs a beauty salon, so this rose essential oil must be used. She has already refined it in the space, and now it's time to take it out and sell it!

The extraction of rose essential oil is difficult or not. Just add fresh roses and water, use the principle of steam distillation to distill a floating white oil-water mixture, and then add sodium chloride (salt) to the oil-water mixture in the second step. Carry out oil-water separation, then use a separatory funnel to separate the essential oil and water, and then carry out further dehydration and purification of rose essential oil to obtain pure rose essential oil.

To extract pure rose essential oil, in this backward ancient times, it is difficult to prepare all the materials and equipment and control the temperature.

Fortunately, there is no shortage of materials in Xiao'er's space workshop, and it's not like they can't find these materials in real life. Now they just wait for Shangguan Xuanyi to bring the things back, and then start teaching Ma Shi to refine them.

The price of rose essential oil Xiao'er is one tael of gold and a half taels of essential oil. After hearing this, Ma thought it was crazy!Who will buy it so expensive!

Later, she began to refine essential oils, and she used up five thousand catties of roses, but she didn't extract much (of course, that was because the roses were not fresh enough). Ma felt that two taels of gold and one tael of essential oils were cheap!After working so hard for a year and a half, there are not a few drops of essential oil. Can this oil not be expensive?If she spends all this time digging for gold, how much gold can she dig up!

Since refining essential oils, Ma started her life as busy as a dog.If she were to set the price, she would definitely ask for one or two gold and one drop of essential oil!
Of course, this is something.

……

After leaving the small house, Jiang Yuheng waited outside the town gate, waiting for Shangguan Xuanyi to return.

He wanted to return to the imperial capital, whether it was for his dead father and younger brother, or for the fifth princess, he had to return to the imperial capital as soon as possible.

Shangguan Xuanyi came back in the sunset, and when he saw Jiang Yuheng waiting outside the city gate, he knew he was waiting for him.

The two returned to the small house together and talked for a long time in the study.

Jiang Yuheng expressed his desire to return to the imperial capital as soon as possible, but he also knew that he was no longer the son of Duke Zhenguo, and whoever would recognize him after he returned might be beaten to death before entering the city gate!
Jiang Weiqiang is a scheming man, and his body has never been found. Perhaps it is not surprising that he has sent people to guard the city gate for so many years.

Jiang Yuheng did fall into the water when he fell off the cliff, and was directly swept away by the panting current. Later, he was probably washed ashore by the water, and was rescued by chance by a watchman who went into the mountain to collect firewood.

It can only be said that he should not die!

Shangguan Xuanyi naturally supported Jiang Yuheng's return to the imperial capital as soon as possible, but after trying Jiang Yuheng's skills, Shangguan Xuanyi changed his mind. The martial arts are too bad, should he go back and seek death?
In ten years, the current Zhen Guogong's mansion has long been Jiang Weiqiang's people inside and out.

And now Jiang Weiqiang is the Duke of Zhen, and Jiang Weien is the eldest son, who was appointed by the emperor himself!

Jiang Yuheng couldn't produce any evidence that Jiang Weiqiang was responsible for the deaths of his father and brother ten years ago, so it was impossible for him to return the position of Duke of Zhen!

After all, this is not a child's play, and you can pay it back if you say it.

The two discussed it, and it was impossible to seek justice on the surface. Jiang Yuheng also worried that the old man would not be able to bear such a blow. The second son killed the eldest son's family, and the grandson turned back to revenge on the second son. An old man would not be willing I saw it, so Jiang Yuheng chose to assassinate. He has not many relatives left in this world.

Jiang Weiqiang actually disregarded the interests of the country and the safety of the soldiers for his own selfish desires, and set up a plan to kill his own brothers and nephews. Such a person deserves to die, and even the emperor will not fully condone it, but the premise is that there is evidence, and there is no evidence. Everything is one-sided words.

But after ten years, the Xiyue Kingdom has been destroyed, and all the damned people are dead. If you want to find evidence, you will undoubtedly find a needle in a haystack.

Shangguan Xuanyi and Jiang Yuheng grew up together, so they naturally believed in him and were willing to help him.

If Jiang Yuheng wants to avenge himself, he can only practice martial arts, and then find an opportunity to assassinate him.

In the long river of time, everyone is sailing against the current, and if they do not advance, they will retreat.

The days when Jiang Yuheng lost his memory for ten years were the days when he was stagnant, and if he did not advance, he would retreat!Although he does a set of punches every morning to exercise his body, his martial arts are no longer as good as ten years ago, while Jiang Weiqiang and Jiang Weien are constantly improving, and their power is constantly growing.

Jiang Yuheng wanted to kill them now, it was impossible.

Shangguan Xuanyi decided to arrange for Jiang Yuheng to join his personal guards. Although the hard training there was not as difficult as that of the secret guards, the training was still very strong.

So Jiang Yuheng became a personal guard of Prince Rui's Mansion under the name of Liang Dali.

Shangguan Xuanyi gave him a token and asked Zhao Yong to take him to report tomorrow.

Shangguan Xuanyi's bodyguard training camp is not in the imperial capital, but in a dangerous place, except for his bodyguard and himself, no one else knows.

The two discussed many things, and Jiang Yuheng didn't leave until the middle of the month.

Shangguan Xuanyi returned to the room, and Xiaoer was studying several sets of relatively successful data for drying roses today.

She recorded the amount of firewood used, heat, time, how many dried flowers can be obtained from a catty of fresh flowers, etc., and calculated an average value.

In the future, we will follow this average value to do it, and generally there will be no mistakes.

Shangguan Xuanyi bent down and hugged Xiao'er directly from behind, resting his head on her fragrant shoulder: "Are you done with your work? Are you tired?"

"I'm done, I'm not tired." Xiao'er's energy is relatively good, even if she is standing on the scented tea that has been baked for a day, she doesn't feel tired.
