Su Chen carried the herbal basket on his back, left Yaowang Villa, and went to other counties to carry out the task of delivering letters and miscellaneous labor.

Leaving the prosperous county town of Gusu, to the deep mountains and mountains seventy or eighty miles away, it is almost a deserted place that is inaccessible. Even hunters who hunt for a living rarely set foot in this kind of place where tigers and wolves are often seen.

On the way, Su Chen drilled into the deep mountains and old forests, and found a rock to sit on the ground in the empty and silent dense forest.

Only then did he take out the heavy book of jade slips hidden close to his bosom.

This jade book is made of eighteen pieces of fine jade, threaded with exquisite gold threads, like the shape of a scroll of bamboo slips, but no words are engraved on it.

A month ago, he explored the Hanshan Taoist Temple at night, and failed to find the stolen goods colluded between the Qinghe Dao chief and the water bandit Ding Thirteen, but found such a mysterious book of jade slips in the secret cabinet of the secret room, which can be regarded as an unexpected gain.

However, looking at the Hanshan Taoist Temple, the county government was mobilized to search and arrest the city, and the amazing posture of the five major groups of disciples was mobilized to control and suppress the entire Wu County, which is enough to prove that this lost treasure book is extremely important to the Taoist priests. Perhaps more valuable than the ten heavy chests of gold and silver jewelry in the secret room.

"Could it be that this is the legendary wordless heavenly book, which hides the cultivation mysteries of the Hanshan True True Grandmaster Realm?"

Su Chen looked at the jade book and thought with some curiosity.

In the many miscellaneous books in the library pavilion, there are some legendary stories of heroes in the rivers and lakes, and it has been mentioned that there are no words in the rivers and lakes. In this wordless heavenly book, there are often peerless secrets of the grandmaster realm, and after cracking, you can become a peerless master and be proud of the world.

Of course, these are just legends, not true.

It's not hard to leave a handwriting in a book that isn't visible to the naked eye. With some special tricks, you can hide the contents of the book.

Su Chen had seen it with his own eyes, there was a secret letter from a senior pharmacist, writing words on white paper with rice soup, and after drying, there was no trace, and the handwriting was not visible to the naked eye.

When it is delivered to the recipient, it must be smeared with a mysterious potion that can reveal blue or reddish-purple text.

In this way, if someone peeps at the letter, then the recipient will see the blue handwriting and will also notice that the letter has been peeked at.

This is just one of the most common ways to send confidential letters, in case the sender peeks at the contents of the letter.

Su Chen has seen this kind of wordless secret letter a few times, and he has long been familiar with it and accustomed to it.

Most of the so-called mysterious wordless heavenly books on the rivers and lakes actually have words, but they use different secret methods to hide the words inside.

"I'm afraid that this book of jade slips is also like the pharmacists, who used the secret method to hide the mystery, as long as you find a way to make it manifest. ”

Su Chen couldn't help but get excited when he thought about this.

Cracking the secret of this Book of Jade Slips is also a rare pleasure for him.

This jade is not paper, and of course there is no scribbling on it with rice soup.

Su Chen pondered for a long time, and projected the jade slip against the strong sunlight to see if there were small characters carved inside, but with the strength of his eyesight, he couldn't illuminate anything inside.

Su Chen soaked it in clear spring water again, but it still didn't work.

If you can't use water, then burn it over fire and see if you can bake it!

Anyway, this is an empty wilderness and mountainous area, and it is made of jade, which is not afraid of fire and cannot be burned.

Su Chen boldly burned it with fire, first with a small flame and slowly roasted the jade slip, but there was no reaction. Then a raging fire was raised by a bonfire, and these eighteen pieces of jade were burned red by the fire, but they were still the same.

Su Chen couldn't figure it out, so he had no choice but to give up the method of burning.

Su Chen thought of all kinds of strange methods, but none of them worked, and there was no handwriting on this jade slip book.

"It's strange, could it be that these eighteen pieces of white jade are just pure jade, and they are not the treasure books of the Grandmaster Realm at all?"

"But that doesn't make sense!"

"In the secret room of the head of the Qinghe River of the Hanshan Dao, there is such a treasure hidden in the secret cabinet, which is more tightly hidden than the gold, silver and jewelry of the other ten heavy boxes.

If it doesn't work, why does the Qinghe Dao chief keep it so carefully hidden? Why does the Taoist temple make such a big fuss, please mobilize the official government officials to seal the city, and even the entire Wu County Jianghu gang, come after me?"

"If this is not a treasure book of the Grandmaster Realm, just more than a dozen beautiful jades, this jade itself is not very valuable. It's not worth the effort!"

Su Chen was holding the book of jade slips in his hand, but he was not allowed to enter. It took a few hours of effort to study this jade slip, and I couldn't figure out what secret method this jade slip used to keep it secret.

Su Chen pondered for a long time, and finally bit his lip.

I don't know if soaking this jade slip in turbid water will have a special reaction.

His bluestone is quite magical, after grinding into powder and dissolving into turbid water, it can be used to make herbs grow rapidly and grow overnight for a year.

It's just that there are fifteen bluestones left in his hand, and one grain is missing, so he doesn't want to use it unless he has to.

But now I've tried all kinds of methods, but it still doesn't work.

Su Chen gritted his teeth and decided to give Qingshi a try.

If you don't try it, who knows if it will have an effect? Although this bluestone is also quite rare, if you don't use it, it is equivalent to some waste stone grains after all, and it is not as good as cracking the secret in the Book of Jade Slips.

He took out a grain of bluestone from his small cloth pocket, selected a piece of the rock and made it hollow, smashed it with a stone and ground it into powder, poured it like some clear water, and dissolved it into a pool of green and turbid water.

Then, put the Book of Jade Slips into it and soak it.

Su Chen just stood aside, his eyes widening to see the changes.

But nothing seems to have changed for a while.

Su Chen stared at it for a few hours, and his eyes were a little pantothenic.

It wasn't until it got dark that it was getting darker.

Finally, this book of jade slips has been soaked in the turbid puddle for a long time, and even the cyan color of the turbid water has disappeared.

These handwriting are finer than mosquitoes and flies.

Su Chen's eyesight is extremely strong, but he can distinguish it.

On the eighteen jade slips, each of them showed a piece of text as thin as a mosquito and a fly, and some even had patterns on it.

"Haha, there is indeed handwriting on this jade slip treasure book, the turbid water is amazing!"

Su Chen was pleasantly surprised.

He just risked paying the price of a bluestone and gave it a try, but he didn't expect this method to work.

He didn't know why his bluestone could crack the Book of Jade Slips. Perhaps, what does the bluestone have to do with this Book of Jade Slips?

But as long as you can crack the secret of the Book of Jade Jane, that's it, no matter how much it is.

Su Chen hurriedly carefully studied the handwriting on it.

The first jade slip shows the handwriting such as "Getaway * Mayfly", and there is also a short text introduction, saying that this spiritual book contains an extremely mysterious method of cultivating immortals during the Qi refining period, as well as some commonly used spiritual techniques, and the production of spiritual runes.

The second jade slip records the details of the "Mayfly Chapter", an incomparably mysterious method of cultivating immortals during the Qi refining period.

Of the remaining sixteen jade slips, eight of them each recorded a spiritual technique, and the other eight each recorded a spiritual rune, for a total of eight spiritual techniques and eight spiritual runes.

"The method of cultivating immortals during the Qi refining period, as well as the method of making spiritual techniques and spirit runes?!... This is the Book of Immortal Cultivation for Immortals?"

Su Chen looked at the introduction on this jade slip and couldn't help but be shocked in disbelief.

This jade slip dares to claim to have recorded the method of cultivating immortals, and it is definitely a rare and peerless treasure in the world.

If this book of jade slips was found in the library of the Medicine King Gang, or in a bookstore in the county seat, Su Chen was afraid that he would think that it was a book compiled by a rural Taoist priest.

But this is what he stole from the secret room of the Hanshan Taoist Temple, and it is the treasure of the Taoist Temple.

"No wonder the Hanshan Taoist Temple attaches so much importance to it, it turned out to be a book of cultivating immortals. ”

"This kind of immortal book, it must not be Qinghe Lao Dao who has this ability, it must be an immortal book that Hanshan real people went out to find when they traveled. I don't know where I found it, what kind of immortal cultivation method is this "Getaway"!"

"If he loses such a treasure, the Qinghe River Chief will definitely be unlucky! However, who let him collude with the water bandit Ding Thirteen and harm the people. Hmph, although he couldn't collect the booty of his bandits. But if he lost this immortal book, it hurt more than a knife to him, and he would definitely be punished by the real people of Hanshan. ”

"If this is really a book of immortal cultivation, doesn't this mean that in addition to peerless martial arts masters, there are really immortals in this world?"

Su Chen was pleasantly surprised, and his face turned red with excitement.

Since he joined the rivers and lakes, he is still only a first-order small person in the Medicine King Gang Miscellaneous Service Hall, although he is already a second-rate expert, but in the entire Wujun rivers and lakes, it is just one more, one less small role.

He never thought that one day in his hands, he would be able to get a magical book of cultivating immortals.

Su Chen was also in Gusu County, listening to those storytellers spitting about folk fairy legends, but he always thought that this was a legendary story and did not take it seriously.

Unexpectedly, these legends are likely to really exist... It's just that it's very far away from the rivers and lakes.

I'm afraid that only a worldly master like Hanshan Zhenren in the rivers and lakes of Wu County will have the opportunity to come into contact with one or two, and get such a volume of the method of cultivating immortals.

Su Chen's face flushed with excitement, as if he had found a treasure, and quickly swept the handwriting and spirit runes on the eighteen jade slips.

When he saw the spirit talisman on one of the jade slips, he was suddenly stunned.

A pattern of flames!

It's so familiar!

Su Chen instantly remembered that when he first broke into the room of the Qinghe River Chief, he had found a mysterious flame talisman on his desk.

He took the talisman in his hand, and when he felt it, the heat almost burned his hand.

But then Su Chen went again for the second time, but there was no trace of the talisman, and he didn't know where it went.

He couldn't help but feel a stir in his heart.

"Could it be that the mysterious talisman was made in accordance with the method of making the spirit talisman recorded in this immortal cultivation method?... From this point of view, Hanshan Zhenren and his five great personal disciples, Qinghe Lao Dao and others, should have also cracked the mystery of this Book of Jade Slips and tried to make spirit runes!?"
