As soon as he heard that since he was not there, he didn't need the necessary politeness, and immediately said: "Okay, set sail, Shiniuling Zhuangzi." ”

Han Si bowed slightly: "Shaojun, there is no need to be in such a hurry, it is okay to leave at the beginning of tomorrow." ”

"Okay, let's arrange it."

"Yes."

Han Si retreated, Han Jiang leaned on the soft chair and prepared to rest for a while, but the screams in the courtyard were endless, and Han Jiang's scalp was numb when he listened. Han Jiangxin said that he didn't know that it was the rule set by the family of that generation, and for the domestic servants who committed crimes with sufficient evidence, they always beat them first and then questioned them.

Han Jiang asked: "Ying, inquire, how many of them are still not asked?" ”

Ying went out to ask for a while, and came back to report: "Shaojun, there are four of the heaviest, I heard that it is necessary to stop for a while to let the executioner eat, drink and rest for a while, and someone has already gone to prepare new rattan, and fifty rattans must be prepared." ”

Han Jiangxin said that this is to beat the rhythm to death.

Han Jiang got up: "Take my robe and go out for a walk." ”

Ying asked, "It's getting dark, where is Shaojun going?" ”

"Just walk around the water's edge and I'll come back when they're done."

Ying took Han Jiang's robe: "Shaojun, if you want to go to the water's edge, go to the direction of the dock, this side is the boundary of our mansion." ”

"Yes."

Han Jiang agreed.

Outside the door, Ying said to the two entourages who followed Han Jiang: "Bring the cannon, in case something happens." ”

"Yes, girl."

After going out and walking not far, Han Jiang saw the lights on the dock, but he didn't expect the courtyard to be so close to the dock, but it was good and safe. There are family members in the annex, and there are guards from the Han government at the dock.

Tonight is a full moon, so you can see the road without a lantern.

After walking a short distance, an entourage walked quickly to Han Jiang's side: "Shaojun, there are people in the forest over there." ”

Following the direction pointed by his entourage, Han Jiang saw that there were several people standing next to a small forest, and there were men and women, but they were standing separately, there were three lanterns in total, all of which stood still.

Han Jiang also stopped, and at this time he saw a person by the river, sitting on a stone and watching the fire.

Paper-burning?

No, the fire was clearly a pyre.

At this time, Han Jiang saw that the people by the river had picked up a little ash from the fire, and then grabbed something from the side and mixed it with the ashes.

Out of curiosity, Han Jiang motioned to his entourage not to follow and walked towards the river by himself.

Just as they found out that there were people from the forest side on the other side, the people standing at the forest side also found the three people on Han Jiang's side.

Seeing that the lantern did not move, the people on the edge of the forest seemed to argue, and finally did not approach the river.

Walking to the riverside, Han Jiang saw clearly what this person was doing, and was mixing the ashes of plants and trees into oil to make a black ball.

Han Jiang couldn't help laughing, turned around and prepared to leave.

The person sitting on the stone suppressed his voice and spoke: "Brother Tai, why laugh. ”

As soon as he heard Han Jiang speak, he knew that there was a girl in men's clothes in front of him, and he was not very old, Han Jiang didn't want to fight for anything, but said: "It's just interesting, forgive me for being rude." ”

"It's learning, not fun."

"Learning?"

The other party seemed to be very serious, and immediately said: "From the knowledge of Fanshang, this is the method of making soap in the Great Qin of the Ancient Western Regions." ”

"Thank you for explaining, please forgive me for the interruption." Han Jiang bowed, turned around and left.

But if you leave, this encounter will be over.

And the other party didn't seem to say anything more, concentrating on kneading the black oil dumplings.

Han Jiang took a few steps and stopped.

"Girl, there are three rumors about the method you use. The first is that 4,000 years ago, Mesopotamia mixed grease with plant ash, a country between the two river basins, the Euphrates and Tigris. The second is the Gauls, and the third is the Romans, which is what you call the Great Qin of the Western Regions, which is the most reliable statement. A thousand years ago, the ancient city of Rome already had workshops dedicated to the production of soap. ”

With a girl, the person sitting almost fell headlong into the river. Her head was a little dizzy with the rest of the words, and she barely heard them.

The girl said in her heart, I obviously changed into men's clothes, or a man's headdress, my maid didn't see it, and the family in this house didn't see it, how could this person see it at a glance.

Run, run.

Just as she was about to shout, Han Jiang calmed her down with a word.

Han Jiang said: "You really want to make soap, I'll teach you how to do it." Do not use plant ash directly, soak it in water and put an egg in water. When the egg floats in the water, does not sink, and does not float on the water, it proves that the amount of plant ash is just right. ”

"Then the oil is refined, mixed with the refined pure oil, and the essential oil is added when it is boiled over low heat, and then put it in the mold. It can be barely used after three days, and it will definitely be good after seven days. This thing is called soap, and I believe it can surpass all bath beans and soap horn products on the market. ”

The girl suddenly stood up: "I don't believe it. ”

"Believe it or not." Han Jiang raised his leg and prepared to leave.

"No one will easily tell others such a secret recipe."

Han Jiang stopped: "This is just a rudimentary method, I have a method that can be industrially mass-produced, you just see that you are studious, so I taught you a little, or the sentence just now, believe it or not." ”

"Then have you heard that there is a huge building in Great Qin in the Western Regions, built of stone, twenty zhang high and sixty zhang long. Why is it piled up with stones, it is not the way our city wall was built, but it is also extremely strong. ”

Han Jiang looked the girl in front of her up and down, she was not amazing, only these big eyes were very attractive, especially at this time, these eyes full of anticipation were so focused.

Han Jiang glanced up at the full moon, lowered his head and pondered for a moment: "Because of Roman cement." ”

"What is Roman cement?"

"A kind of ash powder made from the ash of Mount Vesuvius and other things, when mixed with water and stone, hardens and is as hard as a stone, and can remain for thousands of years without being damaged by wind and rain."

"No, can't you make it without that volcano?"

"No, take Yanzhou as an example, I know that there are three alternative materials, but the effect needs to be tested." Speaking of this, Han Jiang turned his words: "Look at your clothes, as well as the housekeepers and maidservants waiting over there, you are also from a famous family, and it is useless to care about cement, I can tell you how to make transparent glass in the Western Regions." ”

"No!" With a no, the girl's eyes were firm: "Cheap soap can be used by ordinary people." The method of building with huge stones and high walls can defend against the enemy of my Great Song Dynasty. ”

Han Jiang shook his head: "Girl, your mood is understandable, but you are still young." Song was not defeated by the lack of high walls, but by the hearts of the people. The fort can only be defended, and the result can only be more sad. Gone, the night is cold, the wind is strong by the river, and the girl will go back early. ”
