In this thin book called "Secret Recipe", there are more than a dozen secret recipes, including a secret recipe on how to mix dyes, which can be handed over to Uncle Qiao to use in his own auspicious cloud silk village after going back. There is also a way to make glaze, with this secret recipe Daming does not need to buy their glaze from the western countries, maybe in the future Daming ordinary people can also afford to buy glazed products. There are also several recipes for spices used in cooking. What excites Jia Min the most is that there is a secret recipe for making ice, which is not only simple but also extremely low cost, and there is no geographical limit, even in a hot place like Linjia Island, you can also use this secret recipe to make ice.

Jia Min feels that she is so lucky, every time she needs something, God will send her what she needs. Jia Min's whole heart is very good, and he is looking forward to getting dark and Lin Ruhai coming back soon.

In the evening, Lin Ruhai returned to Zhiyuan Hall in a sweat, said hello to Jia Min, and went straight to the underground bathroom to bathe. Jia Min took a piece of Lin Ruhai's clothes from the cabinet and followed him into the underground bathroom.

"Husband, I've prepared some mung bean soup, it's already cold for you, do you want to bring it to you now?"

"It's good that I'm uncomfortable at this moment, drinking some mung bean soup can also relieve the heat" Lin Ruhai took off his soaked clothes and stepped into the bath.

Jia Min put Lin Ruhai's change of clothes on a white jade bench next to the bathroom wall, and then turned out to give Lin Ruhai the mung bean soup and cut it in.

Lin Ruhai took the mung bean soup, drank it in three or two sips, and sighed, "Everything on this island is good, but the weather is too hot."

Jia Min took the empty bowl handed over by Lin Ruhai and said, "Husband, I have a way to make the people on our island no longer suffer from the high temperature."

"Oh, Min'er, if you have any good ideas, say it quickly, thank you for your husband" Lin Ruhai laughed at Jia Min while scrubbing this.

Jia Min glared at him angrily and said, "Husband, I mean seriously, but I'm not joking with you."

"I'm also very serious, Min'er looks at me where I'm not serious, I don't pull Min'er to take a mandarin duck bath with me," Lin Ruhai pretended to look at Jia Min seriously.

Jia Min rolled his eyes and said, "I won't joke with you, I found a book in the space today, which records more than a dozen secret recipes, including the secret recipe for making ice." If we have ice, won't we be able to suffer a lot less?"

"Ice making, we don't have ice caves here, how to make ice," Lin Ruhai was also interested.

"This method doesn't require an ice cave at all, just a little saltpeter."

"Saltpeter is really fake, can saltpeter make ice, we have a lot of saltpeter here, but they are all used to make explosives"

"Wouldn't you know if you really tried it?" Jia Min was still very confident in the book left by the medical fairy.

Lin Ruhai thought for a while, then quickly finished scrubbing, asked Jia Min to help him dry his son and change into dry clothes, and then went to the courtyard to play the dog flute. In a moment, the old shadow appeared in the courtyard of Zhiyuan Hall, and saw that Lin Ruhai's hair was scattered, and he had not yet cooled down, and one of them was in a hurry, so he hurriedly asked Lin Ruhai "Master, but what happened?"

"It's not a big deal, you go find some saltpeter, I need it urgently"

Although the old shadow wondered what Lin Ruhai was suddenly anxious about what he wanted saltpeter, he didn't delay for a moment, and quickly sent it to Lin Ruhai. When the old shadow asked Grandpa Nine to ask for saltpeter, Grandpa Nine was also very curious about what Lin Ruhai planned to do with saltpeter, but Lin Ruhai did not explain, and Grandpa Nine did not ask directly.

Lin Ruhai and Jia Min went to the underground bathroom together, where the temperature was low, which was conducive to ice making. Jia Min asked Lin Ruhai to scrape the saltpeter into powder with a dagger and put it into a bowl filled with water according to the proportion in the secret recipe. Next, the two of them watched in amazement as the bowl of water first rose with white smoke, and then gradually turned into ice at a visible speed.

"This Min'er, you are really our Lin family's great fortune star, such a magical secret recipe can be found by you, and it is also what our Lin Jia Island needs the most, no, no, not only Lin Jia Island, this secret recipe for ice making can make the people of Daming not suffer in the summer heat, this is another merit for the benefit of the people."

"I also think that I am really lucky, but I was bored when I rummaged through the book in the space to relieve my boredom, and I actually found the secret recipe This ice can be made, and the other secret recipes in the book must also work."

"What other secret recipes are in the book?" Lin Ruhai asked.

Jia Min flipped through the thin "secret recipe" in her hand, Lin Ruhai took it and looked at it, his smile became bigger and bigger, and finally he directly picked up Jia Min and turned around a few times, laughing insolently.

"Husband, let me down, I'm dizzy," Jia Min patted Lin Ruhai's shoulders with his two small hands and said.

Lin Ruhai stopped spinning, but still hugged Jia Min and said, "What's the matter, is the dizziness so dizzy, I'm overjoyed?"

Jia Min shook his head and said, "It's okay, it's much better, my husband is really, like a child"

"Hahaha, I'm so happy, don't say anything else, just this method of making ice and glass can bring huge benefits to the people, and it can also make my Min'er make a lot of money"

"Husband, I plan to make the secret recipe for ice making public, so that ordinary people can also use ice in the hot summer. As for the glazed recipe, I plan to ask my husband to come forward to talk to the emperor, let's spend money to build a glazed workshop, in the name of the imperial court, and the interests of the imperial court and our Lin family are half of each. ”

Lin Ruhai thought for a moment and understood what Jia Min meant. There is no technical content in saltpeter ice, rather than holding it in your own hands, it is better to give Lin Jiabo a good name. Liuli's profit is too great, and it is not impossible to keep this secret recipe with their Lin family's ability, but it will offend some people, and it will take too much effort, and they don't have extra effort to use to protect Liuli's secret recipe. And cooperating with the emperor will eliminate the possibility of people wanting to snatch the secret recipe, and it can also make the relationship between the Lin family and the emperor closer.

"It seems that my little wife is not only lucky, but also has a smart head, and I, Lin Ruhai, am really lucky to be able to marry Min'er as my wife, and to be treated sincerely by Min'er"

"So my husband has to take care of me, maybe when I can bring some surprises to my husband," Jia Min joked with a smile. The chapter content is being restored, so please visit it later.
