Just when Zhang Ai was at a loss for this wordless book, an unintentional move made Zhang Ai's eyes shine.

Zhang Ai, who was born as a salesman, habitually wrote his name on the first page of the book, and then it was the moment to witness the miracle.

I saw a fine light scattered from the book, and it also illuminated Zhang Ai's small room in broad daylight, and then some words began to slowly emerge on the book.

When the words appeared on the slightly yellowed paper one by one, Zhang Ai exclaimed, sat down on the ground, and after a while, curiosity overcame fear.

When Zhang Ai patted his ass and got up, he looked at the book carefully.

Zhang Ai only feels that the world is so big at the moment, these words look like calligraphy words, all square and square.

The first line reads, Dynasty, followed by the time, and a shop sign in the upper left corner.

Zhang Ai thought to himself, shouldn't this book still touch the screen, thinking in his heart, Zhang Ai cautiously reached out to the store and clicked.

Sure enough, just as Zhang Ai thought, a list of black pen and ink situations began to emerge on the side of the book.

I saw that the list was full of herbs and books, and in the upper right corner of the list there was a category, and in the upper left corner was a filter.

There are various medicinal herbs in each of these squares, some with a lock painted on them, while some of the ones in the front do not have locks, but are like ink paintings.

Zhang Ai tried to click on one, and saw the detailed introduction of this medicinal material, not only the name of this medicinal material, its medicinal properties, but also the formulas that appeared in the major treatises, and so on.

Click on the classification, which is roughly divided into four categories, namely, herbal medicine, needles, medicinal works, and dialectic.

At present, only one herb has been unlocked, while the others are still painted and locked, and Zhang Ai continued to flip down.

If the shock brought to him by the first page was not big enough, then the second page made Zhang Ai feel like he was really dreaming.

I saw that Zhang Ai was recorded in detail on the second page, and this book can be said to know Zhang Ai better than Zhang Ai.

Name: Zhang Ai, Gender: Male, Nationality: Han Nationality, Age: Twenty-two years old, Marriage: Single, Characteristics: Narcissism, Disadvantages: I don't know that I am narcissistic, Physical condition: average, and many of Zhang Ai's past events that have happened and even some are forgotten are recorded here.

For example, after clicking on the detailed information, one of them is that Zhang Ai secretly ate the lunch at the same table when he was fifteen years old, but framed it to the male classmate surnamed Li at the front table.

And unconditionally cooperate with their table mates to report to the teacher.

Zhang Ai thought to himself, in fact, he was too hungry at the time, otherwise he wouldn't have stolen other people's lunch, but now that he thinks about it, he is really sorry for the male classmate who was framed by himself.

However, a line of words appeared on the tree, which read, hypocritical, without remorse, in fact, I saw fried chicken legs in the lunch box.

"I went, 9999, and was simply 6. Zhang Ai was hit by this line of words.

After reading this book, I can still perceive the true state of my heart, whether it is through the ups and downs of my thoughts or emotional fluctuations, which is unknown.

What I know at present is that this book seems to be very powerful, but Zhang Ai has no way of knowing what the dynasties and times recorded on the first page mean.

Thinking like this, I saw that under the line just now, another line of words slowly emerged, which said that you can write down the dynasty you want to go to, and the time you stay, and you can complete the crossing.

Damn, is it so good, can I come back after I go, is it still me if I come back, if I go to that dynasty, what about modern times, Zhang Ai silently thought about a series of questions in his heart.

Then, the book began to answer myself one by one.

You only need to record the place you want to go in the dynasty line, and you can travel through, and if you go back to modern times, you can leave the time column unfilled.

If you are found to have disappeared for a long time, your family will call the police, or you will hold a funeral.

After reading it, Zhang Ai only felt that his head was full of black lines, that is to say, if he wanted to play crossing, he had to say hello to people who knew him first, such as going out to travel or something.

Just thinking about it, another line appeared in the book, the idea of tourism is good, but it is very naïve and naïve, but there is still room for improvement in hard work.

Helpless, Zhang Ai is only helpless at the moment, thinking that this book is not going to become a refinement, it is so unserious, it doesn't look like a textbook, what kind of system does it become.

Hehehe, I'm not a textbook, you can call me medical history, small history, history history, etc., or you can give me a name, but you have to pay attention to proportion.

Awesome, this is even better than the robots in the QQ group, Zhang Ai can't help but be a little impressed by this book.

Oh, hehe, don't associate me with the low-intelligence AI of QQ Xiaoice, I have brains.

The black letters that kept appearing on the book made Zhang Ai only feel that his life might change because of the appearance of this book.

So I thought to myself, Master of Medical History, what does the lock in the store mean, and can I only learn medical skills through you, so how can I make money?

Zhang Ai, who asked a bunch of questions in his heart, silently waited for the answer to the book.

After a while, the history of medicine began to answer Zhang Ai's questions one by one.

You are now level 1 and can unlock things in the store by leveling up through your knowledge of TCM, while the virtual currency for purchasing goods is monetized by your contribution to the development of TCM.

I am a medical book, so naturally I can only learn medical skills, but not from me, but from all the masters in the history of Chinese medicine.

As for making money, this can only be up to you, maybe you can try to sell me and see if you can get it for a few dollars, but if you sell it, you can't get it back, you can do it yourself.

No, I said why are you so glassy, I just asked how to make money, and I didn't say that I wanted to sell you, so if I buy medicinal herbs or books in the store, what kind of logistics do you take, free shipping, Zhang Ai thought helplessly in his heart.

.............. Instead of logistics, you can set an output point, and after purchasing, it will be automatically transmitted to the output point you set, Yishi replied.

Oh so, then I don't have any problems, I want to know what dynasty I can go to now, how long I can go, is there a limit to this, Zhang Ai thought to himself, I still have to ask clearly, don't wait and never return.

The dynasties that can be selected now can only go to the Qing Dynasty in the near future, and the time cannot exceed ten days, and after the crossing, the development trend of any future situation cannot be revealed to the dynasty, otherwise it will affect the whole body.
