Chapter 23 is quite rich

The carriage was running on the streets of Xuchang, and Cao Shuang was sitting in the carriage and pretending to sleep. After returning home, Cao Shuang handed Cao Cao's secret letter to Cao Zhen, and after reading the letter, Cao Zhen's eyes were like bells looking at Cao Shuang, and his eyes were full of curiosity. Cao Shuang shrugged his shoulders, expressed helplessness, shook his head and said, "I hope my father will forgive me, this matter is confidential." ”

Cao Zhen wanted to put on the shelf of Lao Tzu, but looking at the secret letter in his hand, he shook his head helplessly, "The tiger and leopard will obey your dispatch that day, it is not early, so rest early." Cao Zhen was both happy and disappointed in his heart, happy that his son was reused by Cao Cao, and disappointed that he wanted to know what the secret was, but Cao Shuang didn't say that he was like a cat scratching in his heart, that teasing heart, who knows.

Returning to his small courtyard by moonlight, he saw Feng Hui lying on his desk asleep as soon as he opened the door. Cao Shuang exited the door, looked to make sure that he had not gone to the wrong room, and then walked in with confidence. Cao Shuang gently closed the door and put a cloak on the sleeping Feng Hui, which was rewarded by Cao Cao just now. Cao Shuang's movements were very light, but they still woke Feng Hui up, and Cao Shuang smiled embarrassedly. "Master Cao, you're back." Feng Hui hurriedly got up, rubbed his sleepy eyes, and snatched the jug in Cao Shuang's hand to pour water for Cao Shuang.

"It's so late, why won't Sister Hui go back to her room to sleep?" Cao Shuang looked at Feng Hui with a wicked smile on his face, since Feng Hui lived in Cao Shuang's courtyard, Cao Shuang couldn't help but tease Feng Hui a few words.

Feng Hui looked at Cao Shuang's evil smile, and the deer jumped in his heart, and his face suddenly turned red. Looking at Feng Hui's blushing cheeks, Cao Shuang muttered in a low voice, "Today's children are so precocious. ”

"What did you say, Childe?" Feng Hui finally managed to stabilize his heartbeat, and heard Cao Shuang muttering something in a low voice.

Cao Shuang laughed and sloppily and waved his hand, "What else can I say, I just think Sister Hui is so beautiful today." ”

The red cloud that had just retreated covered Feng Hui's cheeks again, "You hate it." ”

Feng Hui's tone of saying this made Cao Shuang's bones crispy, the hairs on his body stood up, and his back was cold. Cao Shuang shuddered, and hurriedly asked, "Sister Hui, is there something wrong?" ”

"This is the paper that the slave family made according to his father's recipe." Feng Hui said and took out a dozen pieces of paper from the cloth bag, Cao Shuang put the paper on the fine touch, the color of the paper is whiter than the last time, and the touch is not so rough, although the quality cannot be compared with the paper of later generations, but the quality is better than all the paper on the market now. Cao Shuang grabbed Feng Hui's hand excitedly, "This is the paper made according to your father's recipe?" ”

"Hmm." Feng Hui sighed and wanted to pull his hand out of Cao Shuang's hand, but he didn't pull it out after a few strokes.

Cao Shuang didn't think about Feng Hui's feelings at all, and continued to ask, "Can this formula be sold to me, or if the formula is not sold to me, you produce paper for me." ”

"Childe sold the slave family at the beginning, and the slave family is the whole child. Not to mention, let alone the recipe for making paper. When Feng Hui said this, he secretly glanced at Cao Shuang, his face was hot.

"Really, really?" Cao Shuang looked at Feng Hui in surprise, good is rewarded, evil is rewarded, the ancients did not deceive me. Cao Shuang laughed, this is the pie in the world. I spent so much money at the beginning, but I can't figure it all back this time. Cao Shuang's laughter quickly attracted Xu Nu, Li Nu and Li Cong, the three of them looked flustered, and they didn't sleep in the middle of the night, Gongzi wouldn't be the sequelae of being kicked in the head by the war horse last time. Without knocking, the three of them broke down the door and asked in unison, "Childe, are you okay?" ”

At this time, Cao Shuang was still holding Feng Hui's little hand tightly, and the three of them dragged their throats, covered their eyes and turned around, "I didn't see anything, I didn't see anything." Cao Shuang realized that he was still holding someone's hand, and with the laughter just now, Cao Shuang's heart was cold, and it was over, and he couldn't wash it by jumping into the Yellow River this time. Li Nu, who turned around, said with a smile, "We're still worried about our son, it turns out that some beauties are in their arms." Cao Shuang is very approachable, and Li Nu will make jokes about Cao Shuang from time to time.

Hearing Li Nu's ridicule, Feng Hui hurriedly pulled out his hand and retorted with a flushed face, "Sister Li, what are you talking about, people are just here to show Cao Gongzi the paper." Cao Shuang also touched his nose in embarrassment, "Yes, it's not what you think." At this time, it will only get darker and darker, and the three of Xu Nu closed the door and walked out as if they knew what I did. Feng Hui stuffed all the paper in the cloth bag into Cao Shuang's arms and ran out. Cao Shuang yawned, then went to bed to get ready for bed, he was too tired all day. Cao Shuang was lying on the bed, listening to the laughter of Feng Hui, Xu Nu and Li Nu outside, his eyelids became heavier and heavier, and he fell asleep after a while.

After dawn, Cao Shuang asked Li Cong to take Feng Hui to the street to buy the raw materials needed to make paper. When the sun was about to set, Cao Shuang climbed into Li Cong's carriage with a tired body and hurried back to his house. Back in his small courtyard, looking at the scene in front of him, Cao Shuang's eyes lit up.

I saw that there were several wooden basins in the courtyard, and the wooden basins were filled with an unknown liquid, and they were soaked in pieces of moso bamboo. Feng Huizheng and Xu Nu gently stirred with wooden poles. Seeing Cao Shuang walk in, Feng Hui and others saluted Cao Shuang. Cao Shuang motioned to everyone to be exempt, "What are you doing here?" ”

"It's soaking the stuff." Feng Hui replied to Cao Shuang while stirring, looking at Cao Shuang's confused eyes, Feng Hui wiped his hands, and then gave Cao Shuang a popular science. The main raw materials of handmade papermaking are hemp, bark, bamboo, and papermaking has a complete set of production processes. These main processes are: soaking, cooking, washing, whitening, beating, scooping, drying, and baking.

"What's this stuff?" Cao Shuang pointed to the blue liquid in the wooden basin and asked curiously.

Feng Hui picked up a small porcelain vase, "This is the 'blue acid' prepared by the slave father, which can reduce the time for ingredients." It turns out that it takes half a month to soak like moso bamboo, and it only takes two days to add blue acid. ”

"Awesome." Cao Shuang gave Feng Hui a thumbs up, thinking in his heart, what kind of blue acid is this, can't it be sulfuric acid, when will I get a little research, if I can't get it, I can invent some corpse powder or something. Thinking of this, Cao Shuang couldn't be happier in his heart, this is buying a maid, this is simply buying a treasure. I thought I was doing a loss-making business, but I didn't expect to gain a lot. Cao Shuang hummed an unfathomable song and walked towards the room.
