……

After sending Qian Junhao away, Li Anran, who was still smiling, immediately went into his room after closing the courtyard door.

Regarding the bed and copper coins, Li Anran is not worried. Although these two things are from the Tang Dynasty, they have not been precipitated by time. Not to mention the bed, where can the things used by ordinary people be exquisite. The material of jujube wood is not a good thing even in modern times. If it had been baptized for thousands of years, maybe it would still be worth two dollars. But this thing is "fresh" inside and out, and it is worthless at all.

As for copper coins, the same is true, without the precipitation of time, these copper coins that have only been issued for a few years are brought to the antique market, and no one will treat them as antiques. Unless Li Anran knows how to make fakes, and then artificially "rust" these copper coins to take "fake" as true. In this way, there is still a high chance that it will be seen through by experts.

After thinking about this, Li Anran naturally didn't take the matter of the bed and copper coins to heart anymore, and even the one hundred taels of silver cakes in the treasure bag didn't take it seriously. Now the most important thing is to find out whether you have crossed over to Datang because of what you have traveled, and what you have crossed back because of what you have crossed, and this process can not be repeated.

If you want to say that after crossing over to the Tang Zhenguan, Li Anran wants to come back or not, naturally she wants to do it very much. But now that I really have to come back, I feel a little reluctant in my heart. After all, in modern times, he is just a little "god stick" in the countryside. Although the business of doing things for people is not bad, it is not comparable to the career in Datang. Even if the career over there has only just begun, according to the development of things. Not to mention the big one, it's still no problem to open a wine shop and buy a Zhuangzi local owner's old wealth.

As for the benefits of ancient men who could have three wives and four concubines, and who could go to the Qinglou openly, Li Anran, who only talked about a girlfriend in college and was kicked by the other party when he graduated, would never admit his inner yearning.

In fact, there was no need to think about it at all, and Li Anran also knew that this crossing of the Dao must be closely related to the mysterious rune in his mind. But for what reason, he didn't have a rune before he crossed over, and after he crossed, he had a rune but didn't wear it back immediately, and for a while, Li Anran could still come up with a clue.

"Wait a minute!"

Just when Li Anran was about to try his traversing ability through practice again, he suddenly remembered that he had neglected something, and hurriedly opened his laptop, and after entering the system, he looked at the time in the lower right corner.

"Judging from the time I spent with Datang, there is a certain time difference between the two time and space. No wonder when I first walked through, it was night, but when I got there, it was morning. ”

"When I practiced before, it was more than eight o'clock in the evening, and based on the current time, it was more than eight o'clock in the morning when I traveled back before, so the difference between the two time and space was almost twelve hours."

"That's not right! It doesn't matter what the time difference is, the important thing is what I did in Datang, grilled barbecued pork and snow sugar are nothing, but the treatment of trauma is likely to have an impact on the trajectory of history! “

Thinking of this, Li Anran didn't care about any practice tests, so he connected to the telecom broadband installed at home, opened Du Niang and used different keywords to check the content of surgical treatment methods in history. This check took almost an hour. After Li Anran almost went through the history of the development of trauma treatment methods, he did not see that there was any record of suturing wounds during the Zhenguan period of the Tang Dynasty.

Could it be that history really has the ability to correct itself? Or is it that the Tang Dynasty I traveled to is just a Tang Dynasty in a parallel time and space, and it has nothing to do with the time and space I am in? ”

Li Anran, whose mind was full of question marks, didn't know what was going on with Lu Dao for a while. After a while, seeing that no matter how much he wasted his brain cells, he couldn't figure out the truth of the matter, Li Anran simply put this question behind him for the time being.

"It doesn't matter what the hell is his reason, it's true that I'm back anyway. And looking at Qian Junhao's reaction, I am still me, and the Dharma I did before still exists, and it has not changed because of the butterfly effect. ”

"In this case, instead of thinking about this problem, I should think about whether I can return to Datang through the mysterious runes in my mind. If it can be done, hehe! Then I'm cool!! ”

Just when Li Anran knew that Lu Dao was not happy at the moment, he was about to enter the state of practicing cross-legged to test his traversing ability, but he suddenly felt that if he could really cross, wouldn't it be too wasteful to wear it back empty-handed. Thinking of this, Li Anran hurriedly jumped out of bed again and sat in front of the computer, opened Du Niang to search for what business was the most profitable in ancient times, and at the same time, it was the least likely to cause trouble.

In addition to the four sensitive materials of salt, iron, wine, and tea, the method of making glass products was used the most often in many novels that traveled back to historical times. In addition, there are various ways to make soap, perfume, underwear, write scripts, become poets, and even become officials. In fact, when he was in Datang before, Li Anran also thought about doing this.

It's a pity that I don't know how to burn glass at all, and soap, perfume, and underwear are also nine out of ten, and the whole is nothing. As for writing a script, you can consider it, but there are a lot of e-books stored in the copycat mobile phone. Even if modern novels are not suitable, there are also four famous novels, Shushan Swordsman, Liao Zhai Zhiwei, and modern and ancient martial arts, mythology, and romance novels such as Jin Gu Huang Wen that can be "borrowed" one or two.

But if you can really go back and forth between the two time and space, the low-income business of writing a script, although it may be useful in terms of reputation, and at the same time can maintain a certain low profile, but from the perspective of making money, it is far behind. Thinking of this, Li Anran searched again, about what is not valuable in modern times, but it is very valuable in ancient times. As a result, I didn't know the way without searching, and I was shocked when I searched, there were too many things that met the requirements.

After picking and choosing, Li Anran finally selected two types of goods. One is the mirror, which is about the size of an adult's palm, and is specially used for the dressing up of girls. The cheapest thing is only a few dollars, and the more expensive ones are only a few dozen dollars. If you just put it in the Tang Dynasty, which is still using a bronze mirror, it will definitely cause a sensation among those ancient women, and I am afraid that I will not be able to make money.

The other category is gemstones, which of course do not refer to natural gemstones. Rather, it refers to a variety of synthetic gemstones, in addition to the well-known zircon, there are also artificial crystals and even glass jewelry.

As for the plot described in a novel that traveled to the Tang Dynasty, the protagonist took artificial pearls to ancient times and sent them everywhere, in Li Anran's opinion, it was really ridiculous. Artificial pearls are actually divided into two categories, one is artificially cultured pearl mussels, this kind of pearl is also called freshwater pearls, absolutely genuine, even in modern value is not cheap. The other is artificially made imitation pearls, which are generally made of ABS plastic in addition to the shape of pearls, and the material is fundamentally two different things.

If it is just used as a new type of jewelry, this imitation pearl actually has some value, but if it is only used to pass off as a real pearl, it does not need to be ground into powder, and those who know how to do it can see the problem at a glance.

In ancient times, the act of giving away fake goods was quite serious. Li Anran really couldn't figure out how wasteful the ancients in that book, especially those dignitaries, would not be able to discover the authenticity of pearls.

Of course, there are many, many more than glass mirrors and artificial gemstones. But for Li Anran, the early development of these two small and easy to carry, and high-value goods is enough.
