For several days, Wei Renshi and Sun Youqing were in that room and did not come out.

Every time the meal arrives, let the food be sent outside the house, after Wei Renshi and Sun Youqing finish eating, they will put the things out for the next person to take away, there is a bed in the workshop, and the two of them sleep in the workshop at night.

Wei Renshi and Sun Youqing experimented many times in the workshop, and they sent the brown sugar carriage inside three or four times alone. That's when I finally figured it out.

Mixing the yellow mud water directly into the syrup for filtration, the white sugar is produced faster, and the effect is better. With white sugar - although due to technical and equipment conditions, it still cannot be compared with the real white sugar of later generations, but it is also white anyway - then rock sugar can also be made.

Melt the frosted sugar again, put egg whites into it to further remove impurities, and then put in a few pieces of bamboo stalks, and then cool down and coagulate, and wait for one night, you can make rock sugar.

Although it is not as clear as in the later life, it still looks translucent, and it can barely be called rock candy.

Wei Renshi asked Sun Youqing to clean up the house, remember the method of making white sugar and rock sugar, and then go out with a can of white sugar and rock candy.

If you have good things, you naturally have to give them to your family first.

Back in the house, Wei Renshi found Xi'er who was tidying up the study for him in the study, so he pulled her over, and said with a mysterious smile: "Xi'er, come, this son will show you something good!" ”

Xi'er blinked her eyes, and she didn't know why, but suddenly lowered her head with a flushed face.

"Come here!" Wei Renshi saw that Xi'er was motionless, and urged again.

Xi'er's face turned even redder.

Wei Renshi was stunned, went over and knocked on Xi'er's head, and said, "What are you thinking?!" Honestly, who taught you?! ”

"Huh? What do you teach? Xi'er was stunned, but suddenly remembered something, and suddenly her face was even redder, and her cheeks were about to turn purple, and she said in a voice like a mosquito: "They are talking nonsense, Xi'er didn't hear anything!" ”

Wei Renshi smiled dumbly, shook his head, picked up the two jars in his hand, and said, "This is what I made new in the wine shop in the past few days. We're going to add another property to our family. ”

"Oh......" Xi'er seemed to breathe a sigh of relief, but as if she was a little disappointed, she lowered her eyelids and leaned over.

Wei Renshi opened one of the clay pots, and when Xi'er looked inside, he saw that there were square pieces in the clay pots, which were crystal white, like ice crystals, and looked very good.

Wei Renshi took one out of it and handed it to Xi'er, bringing it to her mouth. Xi'er opened her mouth and took the rock candy from Wei Renshi's hand into her mouth, and her eyes immediately widened.

"Lang Jun, this ice is so sweet!" Xi'er sighed in surprise.

Wei Renshi suddenly retracted his hand, and the soft and glutinous touch like a marshmallow from his fingertips made him tremble in his heart, as if he had been electrocuted.

"Xi'er, do you want to eat marshmallows?" Wei Renshi looked at Xi'er's surprised look and asked with a smile.

"What's that?" Naturally, Xi'er had never heard of marshmallows.

"That's it...... Sugar like a cloud. Wei Renshi replied.

Xi'er's head immediately lit up frequently: "Yes!" ”

"Then this son will ......" Wei Renshi paused, and then said: "Uh, this son will go and make tools first." ”

As he spoke, Wei Renshi sat down at his desk, spread out a piece of paper, and immediately drew it.

The principle of the marshmallow machine is actually very simple, and there are only two conditions that need to be met, one is a heating container, which can melt the sugar, and the other is a high-speed rotation, which can throw out the melted syrup into a flocculent.

These two problems are not insurmountable.

Turning can borrow the foot pedal of the old sewing machine of the previous one, and drive the flywheel through the foot pedal, which can be achieved by placing the flywheel horizontally.

Heating the container was a problem, but at this moment, Wei Renshi's brain was inexplicably excited, and he worked efficiently, and almost immediately thought of a way - add a charcoal box on each side of the container, and fill it with coal. The hot container is grilled at the temperature of the charcoal so that the sugar can be melted.

Wei Renshi put down the pen like flying, and then put the pen down, and said to Xi'er: "Okay, leave this thing to the blacksmith and carpenter to make it, and it will be done soon." When the time comes, you can use this thing to make marshmallows. ”

"Lang Jun is amazing!" Xi'er looked at Wei Renshi with little stars.

"Go, give this to the blacksmiths." Wei Renshi led Xi'er out of the study.

As soon as the two of them walked outside the door, they saw a family member running over, came to Wei Renshi, and saluted: "Xiaolang, Mr. Yin has come to visit you." ”

Wei Renshi nodded, walked to the main hall, and saw Yin Qingfeng sitting there with a few wooden boxes.

"Brother Yin." Wei Renshi went over and said, "What good things did you bring here?" ”

"The best tea I've got there." Yin Qingfeng smiled and said, "By the way, the shop that specializes in roasted tea under my new plate will open in five days, and Wei Langjun must enjoy his face when the time comes!" ”

"That's definitely, this is a teahouse I designed, I must go and see it." Wei Renshi said with a smile: "Brother Yin, you sent someone to inform me about this matter, why did you come to Weinan in person." ”

Yin Qingfeng said with a smile: "First, I heard that the scenery here in Weinan is excellent, and there is a smooth new road, so I came over to take a look." Second, there is indeed a bit of thought. ”

"Brother Yin, it's okay to say it." Wei Renshi said.

"These days, the drunken spring building in Chang'an City is very famous, I heard that it was Wei Langjun who had a few stories with it, which attracted many people." Yin Qingfeng said: "I think, Wei Langjun doesn't know if there are any such stories here, but fortunately, after the opening, he can attract more people." ”

"It's a good idea to tell a story in a teahouse." Wei Renshi listened and said, "However, if you can separate the two, it will be better." After all, some people like to be lively, and some people just want to drink tea quietly. ”

Yin Qingfeng nodded and said, "It's exactly as Wei Langjun said." But Wei Langjun don't worry, those elegant seats that will be made according to what you said are all in the back building, and I plan to put some cheap tea in the lobby of the front building, and get a few people to talk, so that I can tell stories to people like Zuichun Building. ”

"And the front building?" Wei Renshi was surprised: "Brother Yin has made a courtyard!" ”

Yin Qingfeng nodded and said, "I'm very optimistic about this roasted tea, so I set up a courtyard to prepare to make it into the guild hall that Wei Langjun said before." ”

"Good!" Wei Renshi nodded and said, "Five days are a bit tight, but this kind of story is also written while telling it, and I don't have anything to do when I come in, so I want to give it to you." ”

"That's the case, thank you Wei Langjun!" Yin Qingfeng thanked.
