"The material of this simple toothbrush is available in this world, but what the hell is this nylon and rubber? Little wolfdog, when the hell was this book? The first way to make a toothbrush was a simple toothbrush, and the materials needed were bristles and bamboo chips, and when she saw the second method, she immediately asked in surprise.

"Well, this book is compiled by Shangxian by bringing together the production methods of ancient and modern Chinese and foreign small commodities." The little wolfdog replied a little stiffly.

"Then why is it written in oracle bones?"

"Uh, Shangxian said that he can only write oracle bone inscriptions, hehe."

After listening to the little wolf dog's answer, Xi Yuexin was speechless.

However, according to the introduction in the mythological novel, Erlang God seems to be a person at the end of the Shang Dynasty, and at that time it was still written in oracle bone inscriptions, Xi Yuexin doesn't remember it very clearly, after all, when she studied ancient history, she was only twelve years old, and she couldn't remember what happened more than ten years ago.

"Then do you know which small commodities on this list can't appear in this world?" Although she is happy to be able to make money, she is also worried that if something appears without her understanding of history, will it change history? If she changes history, will it have an impact on her family in her previous life?

Although she is in the dynasty she is in now, she has not seen it when she studied history, but it is related to the safety of her family, and she still has to be careful.

"I don't know about this, I have to ask the immortals." The little wolfdog shook his head and said.

Hearing the little wolf dog's answer, Xi Yuexin's little face welled up with disappointment: "You don't know, then this book is not of much use to me now." ”

"Of course it works, since it was given by the immortals, it must be useful."

"What if history is changed? Wouldn't I be a sinner for the ages? Although the little wolf dog used an affirmative sentence, Xi Yuexin was still not very relieved.

"Master, the world you are in now is an alternate world, and the world you were in before is two parallel spaces, and the history of the world you were in before will not be affected." As soon as Xi Yuexin's words were finished, the little wolf dog raised one front foot to cover its dog face and said with a smile.

"Since it's an alternate world, then I'm relieved." After learning that it would not cause harm to her family, Xi Yuexin's little face smiled again. "When I went out, I wanted to make this simple toothbrush and sell it, and I didn't need to buy this bamboo and pig bristles with silver." Xi Yuexin, who was completely relieved, said her first money-making plan.

"I'll see." As soon as the little wolf dog finished speaking, Xi Yuexin put the book she was reading in front of it and let it read it slowly, although the other party was just a dog, but now it was her partner, of course she had to have a good relationship with it.

After reading it, the little wolf dog expressed his opinion: "Master, this simple toothbrush is so simple, I'm afraid it doesn't make much money, and it's easy to be learned." ”

"This simple toothbrush is simple, but it is in high demand, and when others learn to make it, I have already earned the first pot of gold, and I can make the next variety." Xi Yuexin said his own countermeasure: "Moreover, didn't you say that there are 10,000 varieties in this book?" As long as this book is here, we will not suffer. ”

"Since the master has already figured out how to deal with it, then I will support the master, by the way, master, there is still something I haven't given you." Seeing that Xi Yuexin's eyes and little face were full of confidence, the little wolf dog was also infected, and suddenly remembered that he still had something important to give to Xi Yuexin.

"What's that?" Hearing the little wolf dog say that he had something to give her again, Xi Yuexin asked with sparkling eyes, and at the same time she was expecting that the little wolf dog would give her gold and silver jewelry and other precious items this time.

The little wolfdog did not answer, but led her to the desk, and after standing still, he said, "Master, open the middle drawer." ”

"Okay." As soon as the little wolf dog's words were finished, Xi Yuexin slowly opened the middle drawer with hope.
