Immortal cultivation starts with copying.

The spirit of the weapon was not willing to say much. It could even open it with ease and see clearly what was inside.

But it cannot tell Chen Yunhao directly. Everything depends on Chen Yunhao to figure it out on his own. This is the path he must take.

After getting a clue from the spirit of the weapon, Chen Yunhao began to study the texture on the secret box again.

The texture on the box is extremely deceptive, otherwise, with Chen Yunhao's meticulousness, how could he have let it go?

The texture on the box is extremely natural, as if it grew there naturally.

From Chen Yunhao's point of view, since the secret lies in this texture, the texture should also be a kind of miniature formation restriction.

But looking left and right, there is no pattern of formation restrictions, only natural texture.

Chen Yunhao stared at it until his eyes were dazzled.

But the spirit of the weapon said that texture was the key, so he had to keep staring at it.

He had been staring at the texture on the box for several hours, and his eyes were really tired and he saw double.

The double image only appeared for a moment, and then disappeared when Chen Yunhao blinked his eyelids.

But it was in this instant that he saw something unusual, because after the two images merged into one, it was no longer a natural texture, but suddenly became an artificial forbidden texture.

"What a brilliant hiding method...!"

Chen Yunhao was amazed, the person who made this secret box must be a genius.

Once you find the method, it will be easy.

Chen Yunhao wiped his eyes with two fingers, making his eyes look blurry as if they were covered with a layer of window paper.

The stripes on the secret box showed double images again, some of which intersected and some did not, forming a new texture.

After looking at it more carefully, it was indeed a restriction. No, strictly speaking, it was not an ordinary restriction, but a special rune.

Moreover, it was a rune he barely recognized, it looked familiar, but upon closer inspection, it was not right.

Chen Yunhao knows how to set up formations and make talismans. The knowledge in his mind is extremely vast and he has read countless classics.

He has some knowledge of the runes of the netherworld, the spirit world, and even the fairy world.

But I don’t recognize the runes on the box. This kind of runes looks older, and it feels like just a few simple lines, similar in shape but not the same.

Although he didn't know it, he still thought about it carefully in his mind for a long time.

Suddenly I remembered a name, which seemed to be mentioned in a very ancient book... Refuting the Elephant's Text.

This is an ancient rune, and it can be said that many modern runes are derived from it.

To be precise, this is a rune that appeared at the beginning of human cultivation records, the first generation of rune.

The more Chen Yunhao thought about it, the more possible it seemed, and he hurriedly searched through the vast ocean of classics in his mustard bead.

He remembered that he had an extremely ancient book, but he didn't know when he had collected it.

It's just that it's too old, and many of the things recorded are from ancient times. It can only be regarded as a legend and is of little use to him now.

After searching for more than an hour, I finally found a book that was earth-gray in color, and I didn't know what material it was made of.

The text on the surface of this book has long been blurred, but the text inside is still relatively clear.

Although this book is very old and written in ancient Chinese, it is slightly more complicated than the current characters. Chen Yunhao can recognize 70% to 80% of the characters.

Although I don’t recognize the other characters, I can guess some of their associated meanings.

After he collected this book, he simply flipped through it and put it aside, treating it as a collection of stories.

I didn't expect that his hobby of collecting would come in handy. Isn't it put to use now?

Chen Yunhao carefully opened the book and found that there were indeed some passages in the book that recorded the ancient Refutation Texts. In addition, on the last few pages of the book, there were many comparisons between the Refutation Texts and ancient characters.

Runes evolved from characters, but were written with special spiritual power. Simply put, they were a kind of text, a symbol, or even a line that contained the laws of heaven and earth.

Boxiangwen is both an ancient writing and a rune. The difference from modern writing is that Boxiangwen uses a large number of lines.

These lines are either circular or wavy, feeling like the texture of trees.

So Chen Yunhao didn't recognize what the texture on the box was. What's more, the maker of the box hid half of the runes, and it required a special method to see them.

Next, Chen Yunhao spent a month comparing the refutation texts in ancient books with the current texts one by one.

Just need to understand the meaning of each refutation text, then you will know the purpose of his engraving on the box.

For example, the Bo Xiangwen character representing the word "天" has multiple meanings. It can represent "up" or "yang".

The word "di" in the Refutation of Xiangwen means "down" and can also mean "yin".

Every word and even every sentence in ancient writing is concise and refined, representing different meanings.

In short, Chen Yunhao spent more than two months guessing and finally figured out what the runes on the box meant.

He analyzed several sentences, one of which he thought was the most reliable.

When a dark moon appeared in the sky and the yin energy was at its strongest at midnight, the moonlight shone on the box and the moonlight box opened.

Chen Yunhao believed that this was the most reliable information among the several pieces of information he calculated.

Of course, whether it is reliable or not, you just need to test it and you will know it clearly.

That night, Chen Yunhao stopped practicing, walked out of the cave, and looked up. Unfortunately, the weather was not good. The sky was covered with dark clouds, and the wind was blowing strongly. A rainstorm was about to come.

With the weather like this, I had no choice but to give up. It has been cloudy for three days in a row.

It was not until the fourth day that a bright moon rose in the sky.

Chen Yunhao stayed up until midnight, when the bright moon reached its highest point in the sky and its light shone directly down.

He took out the secret box and gently placed it on the stone platform in front of him.

Before he loosened his hand, the secret box became like a black hole, and the moonlight floating down from the sky was attracted to the secret box.

Just like when he was promoted, his body would absorb the surrounding spiritual energy.

After a cup of tea, a lotus-shaped opening appeared on the top of the airtight, seamless box in the blink of an eye, like a lotus blooming.

Chen Yunhao hurried forward, took a closer look, and frowned again.

The space inside was very small, with only an object the size of a bird's egg.

It looked like the seed of some plant, and it felt light in the hand, and it was obviously a dried and dead seed.

Chen Yunhao didn't think that this was an ordinary seed. Otherwise, it would be a waste of talent to spend so much effort to store it in such a secret box!
