After seeing Qian Junhao off, Li Anran, who was originally smiling, had no time to worry about the difference after closing the yard gate, and immediately got into his room.

Li Anran was not worried about the matter of bed and copper coins. Although these two things came from the Tang Dynasty, they had not been settled by time. Let’s not talk about the bed. The things used by ordinary people can be exquisite. The materials of jujube wood are not considered good even in modern times. If they were baptized by thousands of years, this thing might be worth two dollars. But this thing is "fresh" inside and outside and has no value at all.

As for copper coins, the same is true. Without the accumulation of time, these copper coins that have only been issued for a few years will be treated as antiques even if they are taken to the antique market. Unless Li Anran knows how to fake it, he will artificially "rust" the batch of copper coins to take it seriously. In this way, there is a high probability that experts will see through it.

After thinking about this, Li Anran naturally no longer took the matter of this bed and copper coins, and even the 100 taels of silver cakes placed in the treasure bag seriously. Now the most important thing is to find out why he traveled to the Tang Dynasty and why he traveled back. Can this process be repeated?

If you want to come back after traveling to Zhenguan of the Tang Dynasty, Li Anran would naturally want to come back. But now he really wants to come back, but he feels a little reluctant. After all, he is just a little "tale" who is hiding in the countryside. Although the business of doing rituals for others is not bad, it is not as good as the career in the Tang Dynasty. Even if the career there has only just started, according to the development of things, it is still fine to open a restaurant and buy a local owner of the farm.

As for the benefits of men who could have three wives and four concubines in ancient times, they could have a blessed shopping mall. Li Anran, who had only had a girlfriend in college and was kicked by the other party when she graduated, would never admit her inner yearning.

In fact, there is no need to think carefully. Li Anran also knew that this time travel must be closely related to the mysterious rune in his mind. But why did he have no rune before traveling, and after traveling, he did not come back immediately? For a moment, Li Anran could come up with a clue.

"Wait a moment!"

Just when Li Anran was planning to try her way through practice, she suddenly remembered that she had neglected something. She quickly turned on her laptop, entered the system and looked at the time in the lower right corner.

"From the time I stayed in the Tang Dynasty, there is a certain time difference between the two time and space. No wonder when I first walked through it, it was obviously at night, but when I got there it was morning."

"I used to practice it at around 8 o'clock in the evening. Based on the current time, I used to calculate it. When I came back from time to time, it was around 8 o'clock in the morning. In this way, the difference between the two time and space is almost twelve hours."

"No! Time difference is not important. What's important is what I did in Datang. Grilled char siu and snow sugar are nothing, but the treatment of trauma is likely to have an impact on the historical trajectory!"

Thinking of this, Li Anran didn't care about the practice test and traveled through time, so he connected to the telecom broadband installed at home, opened the Duniang with different keywords, and found out the historical content of surgical treatment methods. This investigation took almost an hour. After Li Anran almost searched through the development history of trauma treatment methods, he could not see any record of suturing wounds in the Zhenguan period of the Tang Dynasty.

"Is it possible that history really has the ability to correct itself? Or is the Tang Dynasty I traveled to was just a Tang Dynasty in parallel time and space, and it has nothing to do with the time and space where I am?"

Li Anran, who was full of question marks, didn't know what was going on for a while. After a while, seeing that he wasting brain cells could not be able to figure out the truth, Li Anran simply put this problem behind his mind for the time being.

"No matter what the reason is, it's true that I'm back anyway. And judging from Qian Junhao's reaction, I'm still me, and the rituals I did before still exist, and there has been no change because of any butterfly effect."

"Since that's the case, instead of considering this issue, I might as well think about whether I can return to the Tang Dynasty through the mysterious runes in my mind. If it can be done, hehe! Then I'll be happy!!"

Just when Li Anran knew that he was not happy, he was about to enter the state of practicing martial arts to test his time travel ability, but suddenly he felt that if he could really travel through time, wouldn't it be too wasteful to wear it back with his hands empty. Thinking of this, Li Anran quickly jumped out of bed and sat in front of the computer, opened the Duniang to search for what business was the most profitable in ancient times, and it was the least likely to cause trouble.

In ancient times, what kind of business is the most profitable, in addition to the four sensitive materials such as salt, iron, wine and tea, among many novels that traveled to the historical era, the methods of making glass products were used the most. In addition, there are various methods such as making soap, perfume, underwear, writing a storybook, being a poet, and even becoming an official. In fact, Li Anran thought about doing these things before in the Tang Dynasty.

Unfortunately, I don’t know how to burn glass, soap, perfume, and underwear at all, and I know nothing. As for writing a storybook, I can consider it. There are many e-books stored in the copycat mobile phone. Even if modern novels are not suitable, there are four famous works, Shushan Swordsman, Stories from a Chinese Studio, and modern and ancient martial arts, myths, and Romance novels such as Jin Gu and Huang Wen can be "drawn" one or two.

But if I could really go back and forth in two time and space, a low-income business like writing a storybook may be of some use in reputation and can also maintain a certain low-key level, but it is far from the perspective of making money. Thinking of this, Li Anran searched again about what is not valuable in modern times, but is very valuable in ancient times. As a result, I didn't know if I didn't search. I was shocked when I searched. There were too many things that met the requirements.

After picking and choosing, Li Anran finally chose two types of products. One is a mirror, which is a small mirror that is about the size of an adult's palm and is specially used to dress up girls. The cheapest thing is only a few dollars, and the more expensive thing is only a few dozen dollars. Just put it in the Tang Dynasty, which is still using a bronze mirror, will definitely cause a sensation among ancient women, and they are afraid that they will not make money.

The other type is gemstones. Of course, they do not refer to natural gems. Instead, they refer to various artificially synthesized gems. In addition to the familiar zircons, there are also artificial crystals and even glass jewelry.

As for the plot of the protagonist giving away artificial pearls everywhere in ancient times described in the novel that traveled to the Tang Dynasty, it is really ridiculous to Li Anran's opinion. Artificial pearls are actually divided into two categories. One is artificially cultivated pearl mussels. This pearl is also called freshwater pearls. It is absolutely real and is of great value even in modern times. The other is artificially made simulated pearls. In addition to the appearance of pearls, this thing is generally made of ABS plastic, and the material is simply two different things.

If it is just a new type of jewelry, this imitation pearl is actually of some value, but if it is just used to pretend to be real pearls, it does not need to be ground into powder. Those who know how to do things can see the problem at a glance.

In ancient times, the behavior of giving away fake goods was quite serious. Li Anran really couldn't figure it out that the ancients in that book, especially those nobles, could not find out the authenticity of the pearls.
