Xia Hongsheng looked down at the liquid, then looked at the basin in Zhang Laodao's hand, and asked, "Where do you pour it?" ”

"On the fire, we have to put out the stove quickly." Zhang Laodao said to Xia Hongsheng: "Otherwise, the stove will not be used in the future." ”

"Don't pour it, send someone to fetch some glass bottles, and ...... this thing Alum oil, collect it. Xia Hongsheng said to Zhang Laodao.

"Huh?! Master Hou, this alum oil is very dangerous, if you accidentally get a little bit of it, it is enough to turn flesh and blood into a puddle of black water, what do you want this thing for?! Zhang Laodao asked in surprise.

Xia Hongsheng made a look of ill will and looked at the old Dao, and said with a smile: "Naturally, you are left to extinguish, if you are disobedient, Benhou will ask someone to pour this thing on your head!" ”

Zhang Laodao's face turned pale suddenly, and he was so frightened that he immediately wanted to cry out for mercy, but was interrupted by Xia Hongsheng with a smile: "Jokes, jokes, although this thing is dangerous, it is also very useful, as long as it is used properly, it is very useful." You can't use copper and iron to hold it, but when it is in glass, and the mouth of the bottle should be plugged with a glass lid, and it must not be stained with the body, and it is not okay to spit on the stars, understand? ”

"The poor road understands, the poor road understands!" Zhang Laodao nodded and said.

"What about the man who came with this Hu man?" Xia Hongsheng looked around and asked.

"Him?" Zhang Laodao scratched his head and said, "He seems to be sleeping over there." ”

Xia Hongsheng was suddenly annoyed, followed the direction pointed by Zhang Laodao to the hut behind, and sure enough, he saw a person lying on top of a dry meadow, sleeping soundly.

Xia Hongsheng went over and kicked him on the buttocks.

"Who kicked me!" The man straightened up with a carp, stood up rubbingly, and when he saw that it was Xia Hongsheng, he immediately withered again, and said flatteringly: "Hou, Master Hou......"

"I'll let you translate that Hu Ren's words into Chinese and tell Zhang Laodao, you're idle." Xia Hongsheng looked at the man with a smile: "The weather is not cool today, there is a stove here, it is even hotter, and I can't sleep well." Qi Yong, come, throw him into the pool outside, let him sleep well. ”

"Good boy!" Qi Yongying shouted, jumped over, grabbed the man's collar with one hand, lifted his leg with the other, and lifted the man above his head with one move.

"Ouch ouch! Hou Ye, Hou Ye Xiao will never dare to be lazy anymore Hou Ye! The man begged for mercy loudly: "The little one doesn't dare anymore, Master Hou!" Ask Lord Hou to spare his life! ”

Xia Hongsheng glanced at Qi Yong, asked Qi Yong to put him down, and said to the man: "Benhou pays you a regular salary every month, and he asks you to work, but he doesn't ask you to be lazy. If you are lazy, Benhou will not do anything to you, but just tell you to leave and find someone else. There is always money for a month, and there are many people who want to do it. ”

"The little ones don't dare to be lazy anymore!" The man resignedly admitted his mistake to Xia Hongsheng, and said, "But, Master Hou, you can't blame all the small ones." The two of them ...... The two of them always quarrel, when they quarrel, the small one can't pull it away, and when the beard quarrels, he talks fast like a blast rod, and he can't hear it clearly. ”

"Forget it, go get a piece of paper." Xia Hongsheng waved his hand and let the man pass.

Soon, the man took a piece of paper, and Xia Hongsheng squatted down and put the paper on top of the liquid.

Soon, I saw that the place where the paper had stuck to the liquid had become a charred mass, and gradually expanded, and it became a black charcoal-like thing and rotted open.

Sure enough, it was sulfuric acid.

This thing can play a big role in refining and processing oil, as well as steel. However, it seems that this alum oil does not meet the standard of concentrated sulfuric acid.

Xia Hongsheng touched his chin, it seems that it is quite troublesome to turn dilute sulfuric acid into concentrated sulfuric acid, if the water is evaporated by direct distillation or boiling, but then the sulfuric acid seems to evaporate, causing very serious pollution, right? Xia Hongsheng began to hate himself for not studying science well.

Just as he was thinking about it, he saw a shout from outside and asked, "Excuse me, dare to ask if Gongzi is here?" ”

Xia Hongsheng looked at Qi Yong, turned around and went out to Zhang Laodao's alchemy room, and saw that it was a small servant in the family who came over.

"Childe, that Hu man Arhan went to the house to ask to see Childe, saying that the things he was looking for were found last time when Gongzi ordered him, and the things he explained were done. He brought several boxes, and the housekeeper didn't know what it was or what to do with it, so he ordered the little one to come out and look for the son. The little guy saw Xia Hongsheng appear, so he saluted and said.

"Okay." Xia Hongsheng nodded, and went back to explain some things to pay attention to with Zhang Laodao, and specially warned him not to pour the green alum oil directly with water, and told him that he no longer wanted it on the ground, put it in a glass bottle in the stove, and if the stove was broken, he could get another one. Then he left there and went to his house.

When he arrived at home, he saw Arhan, and when he came out of the spy camp, he lost a lot of weight, and when he saw Xia Hongsheng, he immediately came over to salute, looking sincerely afraid.

"Bring things in." Xia Hongsheng said.

Arhan immediately went out to greet the men and carried the boxes inside.

"Master Hou, the cotton you asked me to find, Arhan asked some people, but they haven't heard of it, but there is a person from the Western Regions in the caravan, who said that after listening to Master Hou's description, it seems to be a white stack. The little one looked for Bai Diezi, and he also felt that it was the same as what Hou Ye described, so he brought some for Hou Ye to identify. Arhan said as he opened the boxes.

Sure enough, it was filled with cotton.

Xia Hongsheng nodded: "Yes, this is it." What about seeds? ”

Arhan respectfully handed over a cloth bag.

Xia Hongsheng motioned to Qi Yong to put away the cotton.

At the beginning, in order to solve the problem of keeping warm during the expedition to Liaodong, Xia Hongsheng wanted to find cotton. Cotton made of cotton jackets, the effect of keeping out the cold is many times better than the cold clothes of today's army sergeants.

At this time, cotton was not planted in large quantities, and was only sporadically planted in the Western Regions, so Xia Hongsheng went to find Arhan. He traveled westward to the caravan, and the countries of the Western Regions were places where he often walked, and Xia Hongsheng planned to ask him to send people to look for cotton and seeds in the Western Regions, but he happened to meet Arhan taking Diyega.

Later, Alhan was forced to quit Diyaga, and when he let Arhan come out, he explained two things to him to do.

The first thing is to look for cotton, and cotton seeds. Because April and May are the time to plant cotton.

The second thing was to ask Arkhand to find out how many caravans would bring back Tyega and register them.

"How many caravans will come back with Bottomega?" Xia Hongsheng asked again.

Arhan immediately took out a booklet from his bosom and presented it with both hands: "Master Hou, all the caravans that will bring Di Yejia back, whether they are for their own use or brought back to sell medicine, the small ones have been written down!" (To be continued.) )
