Youzhou Academy was in full swing to prepare, and Zhao Feng was not idle, he sent all the drawings he drew in the study that day to the blacksmith shop.

What are these drawings? One is the keel waterwheel, although this thing was improved by Ma Jun, but in history, the improvements made by Ma Jun were not perfect, not to mention, Ma Jun at this time did not improve the keel waterwheel. Now that he sent the more complete drawings to Ma Jun and Master Wang, the two of them suddenly had a feeling that this keel waterwheel could be so improved!

The second is a crossbow! The crossbow is a heavy offensive and defensive equipment, Li Jing of the Tang Dynasty "Wei Gong Art of War, Offensive and Defensive Tools": "A shot of its teeth, all arrows rise together, and seven hundred steps." The city fortress in the center was all destroyed, and the building was also upside down. It is called a crossbow. ”

From this, it can be seen that the power of this crossbow is huge. Find a copy of this car crossbow is based on the Qin Dynasty's Qin crossbow design, compared to the Qin crossbow, the power is even more amazing!

The third is the formula, which can also be said to be the manufacturing process, what to make? Toilet paper, of course! Historically, the ancients probably practiced "ninja magic", before the invention of paper, the ancients used small pieces of wood and bamboo to "scrape" their buttocks after defecation, and they were not afraid of scraping hemorrhoids.

Even after the invention of paper, because China has a tradition of "respecting the word paper", and paper is more expensive, it is a disrespectful luxury to wipe the buttocks with paper, so the ancients had to continue to be "ninjas". It wasn't until the Yuan Dynasty that the Mongols didn't care about paper, and their buttocks have been treated "gently" since then.

However, as a modern person who has crossed over, Zhao Feng can't stand this habit of the ancients, think about the scratching back and forth on the chrysanthemum with a small piece of wood after the tuba, who can stand it?

Now, the technological level of Liaodong is finally able to manufacture toilet paper, Zhao Feng didn't immediately write out the manufacturing process and send it over!

"My lord, what is this paper for?" Responsible for the production of daily necessities is the original papermaker, Shi Dali. He held the fluffy and soft paper that had just been made, and looked at Zhao Feng inexplicably. He didn't understand what Zhao Feng was going to do to make this kind of paper.

"You cut these pieces of paper into strips so wide and roll them into rolls!" Zhao Feng commanded while gesturing.

"Oh!" Shi Dali nodded, still not understanding in his heart, but he still beckoned his disciples to come and work!

Looking at the rolls of arm-thick toilet paper in front of him, Zhao Feng was still very proud, he didn't expect this thing to be made by him!

"Lord, what the hell is this thing for?" Shi Dali asked again.

"Do you want to come up with Gong?" Zhao Feng asked rhetorically.

Shi Dali was slightly stunned, out of Gong? What does this have to do with this paper? Immediately, Shi Dali shook his head, "I don't want to!" ”

"Hehe, what did you use to wipe your butt after you came out?" Zhao Feng asked.

"Forehead...... "Suddenly asked such a question, and a rugged man like Shi Dali also felt a little embarrassed!" I usually just take small pieces of wood, or some dried leaves. ”

"Hehe, use this later!" Zhao Feng pointed to the rolls of toilet paper.

"Huh?" Shi Dali never dreamed that this strange roll of paper turned out to be made of this! "My lord, this ...... It's a bit of a waste, right? ”

"What's the waste of this, we should be kind to ourselves, don't you think it's very awkward to use small pieces of wood?" Zhao Feng said angrily, "Besides, the cost of our toilet paper is not expensive, and I don't plan to price it too high, after all, it is something that benefits the people, and it should be affordable for ordinary people!" ”

"The Lord is benevolent!" Listening to Zhao Fengde's words, Shi Dali, who originally wanted to price this toilet paper higher, suddenly dispelled that idea.

"It's nothing, but this thing should be consumed very quickly, after all, it has to be like this every day, so you must produce faster, as for the used, we can degrade it, or make it directly into fertilizer, which will be talked about later! Now you can produce with all your might! Zhao Feng said.

"Yes! I see! Shi Dali nodded.

"I'll take these home first!" Zhao Feng smiled slightly, "When the accumulation reaches a certain level, you come to inform me, I will start to promote, and then start selling!" ”

"Yes!" Shi Dali nodded again.

Immediately, Zhao Feng walked towards the Taishou Mansion with those toilet papers.

"Brother Wind!" As soon as he entered the Taishou Mansion, Bian Xue greeted him, and when he saw the roll of toilet paper in Zhao Feng's arms, he was immediately overjoyed, "You have made all this thing?" ”

Bian Xue, like Zhao Feng, has crossed over, and her thoughts are naturally the same as Zhao Feng, and she is naturally very happy to see toilet paper!

"Of course!" Zhao Feng smiled slightly, "Call everyone here, I'll introduce it to you!" ”

"Okay, you can wait in the yard!" Bian Xue nodded, went to the women's rooms separately, and called the women to the courtyard.

"Huh? Husband, what is this? Zhen Mi was the youngest of the crowd, and when he saw the new gadgets that Zhao Feng brought back, he felt very curious.

"It's all here, aren't they? I'll introduce you to it! Zhao Feng smiled slightly, "This is paper, a special kind of paper!" ”

"And what is this for?" The women were still puzzled.

"It's for cleaning!" Zhao Feng said with a smile.

"Clean?" Outside of Bian Xue, the women still had a puzzled tone.

"That's right, it's after you come out, clean the ****!" Zhao Feng said disappreciatively.

Zhao Feng didn't care about what he said, but after the girls heard it, it wasn't like this, and with a "", the women blushed in unison.

"Hehe, what's there to be shy about, our family will use this in the future!" Zhao Feng smiled slightly when he saw the women like this.

"Hmm!" The women nodded, they could also see the benefits of this toilet paper, but after all, it was such a shameful topic, and they didn't want to discuss anything in depth!

"Alright, let's not talk about that!" Zhao Feng knew that the taste of this topic seemed to be a little heavier, so he immediately changed the topic.

"Ying'er, you're about to give birth, how are you feeling now?" Zhao Feng said softly.

"Well, it's okay, it's just that the little guy is a little dishonest!" Qiao Ying smiled and stroked her high bulging belly, her face glowing with maternal brilliance.

"Well, I must pay attention recently, and you must also help me pay attention to Ying'er's situation, and there must be no mistakes!" Zhao Feng instructed the women.

"I know, Brother Feng, you've said it many times!" Bian Xue said with a slight annoyance. Among the women, I am afraid that there is only Bian Xue who dares to talk to Zhao Feng like this! Although all the women knew that no matter what they said, Zhao Feng would not blame them. But they with deep-rooted feudal mentality would not say such things as Bian Xue!
