Looking closely, the cover of this book is carefully made, it seems that there is a layer of iron inside, and then a layer of unknown skin is covered, and this skin does not know what process is used, and it will not rot for hundreds of years.

In fact, after removing the content of this book, as well as the relics of Emperor Taizu Gao, the book itself alone, Chen Kaizhi felt that this was enough to be called a treasure.

Whether it is the craftsmanship of the production or the materials used, it can be preserved after hundreds of years of baptism, and it is enough to be valuable.

And the reason why Chen Kai noticed the abnormality was because of the sound of the book.

He calmly reopened the book, then gently released his hand, and the book closed again, and then poofed...... The soft sound.

This is almost a tiny sound, which is imperceptible to normal people.

But Chen Kaizhi can detect it, because now his ears are much more sensitive than ordinary people.

"The cover of the book, it seems hollow?"

Chen Kaizhi looked at the book with a puzzled expression, and at this time he was a little hesitant and hollow......

Is there something hidden in it? Or is it just an unintentional act of the people who made the book?

"Why don't you take it apart and take a look."

Chen Kaizhi thought in his heart, but he just wanted to do it, but he hesitated again.

This is a cultural relic, or a cultural relic left by Emperor Taizu Gao, Chen Kaizhi also plans to pass it on to his grandson's grandson!

But curiosity is such a thing, it is the legendary Pandora's box, once the seeds of doubt are planted in his heart, Chen Kaizhi can't be calm.

As...... Check it out......

Okay, just do it, Chen Kaizhi took out the small dagger that Chen Dexing gave him, took a deep breath, he found that he was a little nervous, yes, destroying cultural relics, Chen Kaizhi is not afraid, but the destruction of his own cultural relics is another matter.

It's like if you smash someone's glass, you feel a little guilty at best; But who saw someone smash their own glass? This man...... Neurotic.

Okay, okay, if you don't find out today, Ming'er will have to continue to suffer from this curiosity.

Chen Kaizhi took a deep breath again, and finally started, he carefully cut a small opening along the book cover at the edge of the dagger that was as sharp as clay, and then, the dagger slashed down along the gap, his hand trembled a little, and his heart was like a knife.

In the end, the book cover was completely cut, and sure enough, inside the book cover, there was a metal plate of unknown material, and this metal plate was divided into two layers, hanging in the middle, and there was only a very small gap, but in this gap, it was empty.

I knew it!

Chen Kaizhi wants to cry without tears, although the book is still there, it can still be read, but such a high-quality book, now it is under his own hands, unrecognizable, Chen Kaizhi still feels very sad.

He was trying to find a way to make up for it, but he found that the two layers of metal seemed to be a little different, and he quickly moved the candlestick to look at it, and immediately gasped.

...... on a metal plate There are words......

Sure enough, there is something strange.

Chen Kaizhi was shocked, and hurriedly put the metal plate under the candle flame and looked at it carefully.

This is a carved text, densely packed, with both metal plates on the front and back, and it looks like there are thousands of words in the ocean.

Chen Kaizhi became excited, because after only reading the first line, he found that this was the autobiography of Emperor Taizu Gao.

No, not so much an autobiography as a letter to this fortunate descendant.

An epistle that travels through hundreds of years.

Chen Kaizhi only read the first paragraph, and suddenly realized.

It turned out that the reason why this secret was hidden under the cover of the book was a small trick played by Emperor Taizu Gao, because he only hoped that the person who could really comprehend the mystery of the book would be aware of this secret.

Because this is a relic of Emperor Taizu Gao, no one will dare to destroy this book, unless this person discovers this secret.

But how difficult it is to discover this secret, without incomparably sharp ears, in the ears of ordinary people, this is just the most ordinary voice.

What's more, it is not only a matter of testing the ear, but also the real problem is that only those who often take out this book and read it can continue to open and close the book, and the chance of discovering this secret will increase a lot.

Just imagine, if it weren't for the above two kinds of people, who would dare to destroy the relics of Emperor Taizu Gao when they were full?

Even if there is a change of dynasty, such a book is enough to be priceless, who is willing to destroy it?

Therefore, in this world, except for Chen Kaizhi, who has comprehended the mystery and reads it every day, no one has been able to discover this secret.

When Chen Kaizhi saw this, he couldn't help but take a deep breath, and he had to admire the far-reaching plans of this Emperor Taizu Gao.

But......

How could this clever Emperor Taizu Gao think that it was not his descendants who finally discovered this secret?

When Chen Kaizhi thought of this, he couldn't help but sigh that creation makes people, such a treasure, in these hundreds of years, none of these clans surnamed Chen are willing to cherish it, otherwise, how could it fall into his own hands.

Chen Kaizhi calmed down and read slowly, here is all the experience of reading "Wenchang Tu", Chen Kaizhi is like a treasure, and he does not dare to omit a word.

After reading it once, Chen Kaizhi settled down and pondered in his heart.

It turns out that this qi in the body always feels that it has encountered some obstacle because there is no external force to draw it out.

And to elicit it, you need to use something, medicinal herbs......

A large amount of medicinal herbs are soaked together and brewed into wine to drink.

And these medicinal materials, all of which are extremely valuable, from thousand-year-old ginseng to hundred-year-old Ganoderma lucidum, Chen Kaizhi can't help but be speechless.

I'll go, where is this qi induction, this is smashing silver.

From the experience of Emperor Taizu Gao, Chen Kaizhi can feel how great the benefits will be once he can break through this stagflation.

Emperor Taizu Gao only used four short words - a new look.

What does it feel like to be refreshed? After reading "Wenchang Tu" for so long, Chen Kaizhi has noticed that his body has become completely different from before, so ...... Breaking through this layer of stagflation, it will ...... again

It seems that it cannot wait any longer.

These medicinal materials can actually be collected, and most of them need to be bought with money, and Chen Kaizhi probably calculated silently in his heart, to purchase these medicinal materials, it will cost at least three thousand taels of silver, and this ...... It's just the beginning, because of the experience in the back, it seems that the demand for medicinal materials is also huge, of course, what the latter realm will look like, Chen Kaizhi can't understand it, and now it's better to solve the urgent matter now.

After all, it's about earning money.

Chen Kaizhi couldn't laugh or cry, if it was ten days ago, he might not have had too many expectations, but now, it seems that the opportunity is in front of him - refined salt. ... Friends who read books, you can search for "blue book bar", and you can find this site as soon as possible.
