Looking closely, the cover of the book was carefully crafted, as if there was a layer of iron sheet inside, and then there was a layer of unknown skin on the outside. The skin was not used, and it even did not rot for hundreds of years.

In fact, deducting the contents of this book and the relics of Emperor Taizu Gao, Chen Kaizhi felt that this could be regarded as a treasure.

Whether it is the production process or the materials used, it can be preserved after hundreds of years of baptism, which is enough to be priceless.

The reason why Chen Kai noticed something strange was the sound of the book.

He calmly opened the book again, then gently relaxed his hand, closed the book again, and then made a slight sound.

This almost slim sound is unaware of by normal people.

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

"The cover of the book seems hollow?"

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

Is there something hidden inside? Or is it just the unintentional behavior of the person who made the book?

"Why, take a look with it."

Chen Kaizhi thought to himself, but just wanted to do it, but he was trampled 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!

But curiosity is the legendary Pandora's box. Once the seeds of doubt are planted in his heart, Chen Kaizhi can no longer calm down.

Why not... take a look...

OK, I just did it. Chen Kaizhi took out the small dagger that Chen Dexing gave him and took a deep breath. He found that he was a little nervous. Yes, Chen Kaizhi was not afraid of destroying cultural relics, but destroying his own cultural relics is another matter.

It's like if you smash someone else's glass, at most you will feel a little guilty; but who can see someone smashing their own glass? This person... is crazy.

OK, okay, I won’t find out today, and I will continue to suffer this curiosity tomorrow.

Chen Kaizhi took a deep breath again, but he finally started to do it. He carefully cut a small hole along the book cover with the sharp edge of the dagger that was as sharp as iron. Then, the dagger gently stroked down the gap. His hands trembled a little, and his heart was cut like a knife.

Finally, the book cover was completely cut off. Sure enough, in the book cover, there was a metal plate made of unknown material. The metal plate was divided into two layers, hanging in the middle, with only a very small gap, but the gap was empty.

I'll know!

Chen Kaizhi was still crying and could still read even though the book was still there, but such a high-quality book was now inferior to his own hands and was beyond recognition. Chen Kaizhi was still very sad.

He was just trying to find a way to make up for it, but he found that the two metal plates seemed to be different. He quickly moved the candlestick to see it and took a breath.

There are actually words on the metal plate...

There is indeed something strange.

Chen Kaizhi was shocked all over and quickly placed the metal plate under the candlelight and checked it carefully.

This is a carved text, densely packed, with both metal plates on both fronts and backs, and it looks like it is full of tens of thousands of words.

Chen Kaizhi was excited because he only looked at the first line and found out that this was the autobiography of Emperor Taizu Gao.

No, it is not so much an autobiography, but rather a letter to this lucky descendant.

A letter that has traveled through hundreds of years.

Chen Kaizhi only read the first paragraph and suddenly realized.

It turns out that the reason why this secret is hidden under the cover of the book is a trick played by Emperor Taizu Gao, because he only hopes that the person who can truly understand the mystery of this book can detect this secret.

Because this is the relic of Emperor Taizu Gao, no one dares to destroy the book unless this person discovers this secret.

But it is so difficult to discover this secret. Without extremely sharp ears, this is just an ordinary sound in the ears of ordinary people.

What's more, it's not just a test of your ears, but the real problem is that only those who often take out this book to read can constantly open and close the book, and discover the secret, which increases a lot.

Just imagine, if it weren't for the above two types of people, who would dare to eat enough to destroy the relics of Emperor Taizu Gao?

Even if the dynasty changes, such books are worth a lot of money. Who would have to sacrifice them?

Therefore, no one in this world has discovered this secret except for Chen Kai who has understood the mystery and read it every day.

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

But……

How could this smart Emperor Taizu Gao have thought that the one who finally discovered this secret was not his descendants?

When Chen Kaizhi thought of this, he couldn't help but sigh that fate was so good that no one of these Chen clan members was willing to cherish such a treasure for hundreds of years. Otherwise, how could it be lost to his own hands?

Chen Kaizhi calmed down and read it slowly. All of this was the experience of reading "Wenchang Tu". Chen Kaizhi felt like he had gained a treasure and dared not miss a word.

After seeing it, Chen Kaizhi had just entered into meditation and was meditating.

It turns out that the energy in the body always feels that there is some obstacle because there is no external force to lead it out.

To lead it out, you need to use some things, medicinal materials...

Soak a large amount of medicinal materials together and soak them into wine to drink.

All of these medicinal materials are extremely expensive, from thousands of years old ginseng to a century-old Ganoderma lucidum, Chen Kaizhi couldn't help but be amazed.

I go, this is not a way to attract energy, it is a waste of money.

But from the experience of Emperor Taizu Gao, Chen Kaizhi could feel how great the benefits would be if he could break through this stagflation.

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

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

It seems that we can't wait any longer.

These medicinal materials can actually be collected, and most of them need to be bought for money. Chen Kaizhi calculated silently. To buy these medicinal materials, it would cost at least 3,000 taels of silver. This... is just the beginning, because the experience in the future seems to have a great demand for medicinal materials. Of course, Chen Kaizhi cannot understand what the latter level will look like. Now, let’s solve the most urgent matters now.

After all, you have to make money.
