Just as Lin Fan was in a daze holding the "Collection of Ancient Talismans", Master Chen also finished reading the book in his hand and walked over.

When he saw the scroll in Lin Fan's hand, he smiled slightly and said slowly.

"This scroll was obtained by the ancestor of my Burial Sword Pavilion in a secret realm, the owner of the secret realm should be a charmer, this scroll is a summary of the ancient talismans he collected, although it cannot reproduce the style of the ancient talismans, but it can also be used for reference."

"Master, you keep talking...... Can't reproduce it?"

Lin Fan asked suspiciously, with the handscroll engraved according to the inscription, what can't be reproduced?

Chen Fuzi smiled faintly, answering questions is his favorite, I saw that he first put his left hand behind his back, and then raised his head slightly and said unhurriedly.

"Ancient talismans are like ancient exercises, occasionally circulated in the world, but they can only be used for reference, and cannot really be refined, but the reason for it is really ...... but it's a mystery."

After listening to what Master Chen said, Lin Fan had some clue in his heart, thought for a while, and then bowed his hand to Master Chen.

"Master, the younger generation will choose this scroll."

Hearing this, Master Chen was stunned......

......

......

At the door of the Chuan Gong Hall, Lin Fan ignored the surprised eyes of the middle-aged man, and directly pushed the door and walked out.

In the eyes of middle-aged people, Lin Fan chose two strange exercises, a strange jade slip that could not be used, and an ancient charm that could not be practiced......

But Lin Fan was in a good mood at this time and full of harvest.

When I returned to the Imperial Soul Palace, I found that the master was not there, there was a bowl of broth on the table, it seemed that Qiu Ying had come, Lin Fan smiled and picked up the bowl and drank it all, the soup was already cold, but he still drank it all over his body, and his heart was even warmer.

After Lin Fan stood in the hall and thought about it, he turned his head and walked towards the bottom of the Burial Sword Pavilion Mountain.

Lin Fan said hello to the guards of the disciples, and then walked straight down the mountain, walked to the foot of the mountain, chose a random direction, and ran away.

To be exact, Lin Fan didn't have an actual goal, he just couldn't get too close to the Burial Sword Pavilion.

After an hour of running wildly......

Lin Fan stood in a dense forest between a mountain col.

Looking left and right, there were tall trees all around, a pile of gravel under his feet, some unknown grass growing tenaciously from the cracks in the stones, and there were no traces of wild beasts around.

"That's it", Lin Fan muttered, and then sat down cross-legged to recover the true yuan consumed on the road.

Without the secret skills of the body, running for an hour just on his legs is also a great consumption of Lin Fan Zhenyuan.

Urging the "Five-Element Transformation Decision", with the assistance of the Transformation Tree, only half an hour or so passed, and the true yuan in the body was refilled.

After slowly exhaling the turbid air, Lin Fan carefully took out a light blue jade slip from the sandwich of his clothes.

That's what I'm here for.

In the Chuan Gong Hall, Lin Fan felt the extraordinaryness of the jade slip, and under the temptation, he found that there was a strange energy in the jade slip.

He couldn't wait to find out what was inside, but no matter what was in this jade slip, whether he could cultivate or not, he didn't dare to try it in the Burial Sword Pavilion, who knew what fluctuations it could cause, and his secrets were still unknown.

Lin Fan slowly released a trace of true yuan to Yu Jian.

"Hiss~"

The jade jian's ghostly light flashed, and there was another burst of numbness, the hairs on his body stood on end, and Lin Fan trembled.

"Hahaha...... If you kid want to release some more true yuan, it is estimated that you will be able to turn into a roast chicken", a somewhat illusory figure appeared in front of Lin Fan's eyes and laughed.

"Elder Ling, have you recovered?"

Lin Fan was overjoyed in his heart, but then asked suspiciously.

"But why did you come out of the Divine Sea Space, why didn't I feel it?"

"If you don't come out again, I'm afraid you'll become charred in a while", Ling Lao yelled at Lin Fan with wide eyes.

"You dare to pick up the jade slip that you don't know from to cultivate, I don't know if you have the courage or lack the heart."

Ling Lao blew his beard and glared.

Lin Fan felt a scorn in his heart, pouting and complaining, "It's not that your old exercises are too profound, so I have to find a way out by myself......

Lin Fan complained, but his concern for Ling Lao was still very useful, and then asked, "Do you know this jade slip?"

Ling Lao stared at Lin Fan angrily for a while, shook his head helplessly, squinted at Yu Jian again, and said lightly, "I don't know ......."

"I don't know?", Lin Fan raised his eyebrows, a little unhappy, and thought, if you don't know anything, you will stink on me......

But Ling Lao's voice came again.

"But I know the material of this jade slip."

Lin Fan was a little speechless, "Can you always finish it in one go, how can I stand it when I pant for breath."

"This ...... It's not an ordinary jade slip, but the pith of the Extreme Yin Wood."

"Cathode wood?wood pith?...... What the hell", Lin Fan asked, scratching his head.

"It's an extreme yin wood, stupid to death, you get ......."

Ling Lao glanced at him as if he was looking at an idiot, and then said.

"Extreme Yin Wood is also extremely rare in ancient times, and Mu Sui is the essence of Extreme Yin Wood, and it is rare to give birth to Mu Sui for 10,000 years, and this jade slip is made of the wood pith of a section of Extreme Yin Wood.

In addition to being a top-level wood attribute material, this Extreme Yin Wood Pith also has a special use...... Store Seal Thunderbolt".

Hearing this, Lin Fan's heart sank.

Storage Seal Lightning ......

No wonder, the crispy and numb feeling brought by that energy turned out to be "thundered", which is not right...... It was "electrified".

"Fortunately, no one can cultivate the true yuan now, and open this jade slip.

And no one in the Burial Sword Pavilion knows about it, otherwise it wouldn't be your turn, just saying that the value of this Extreme Yin Wood Marrow is already immeasurable."

After speaking, Ling Lao looked at Lin Fan with a smile.

Seeing that Lin Fan was hairy, he continued.

"Boy, I have to congratulate you first, this Extreme Yin Wood Pulp should be a Inheritance Secret Jane."

Lin Fan was just about to open his mouth to ask what the "Inheritance Secret Technique" was, but after thinking about it, he still forgot it, so as not to be ridiculed again, so he simply waited for Ling Lao to finish speaking.

Sure enough, seeing that Lin Fan suddenly became well-behaved and no longer looked like a curious baby, Ling Lao really didn't tease him, and continued.

"The inheritance of the secret slip refers to the peak master of the ancient period, in order to protect the inheritance of the continuous extinction, will seal a secret technique or exercise, together with the special materials needed to cultivate it, in a jade slip made of a special material.

This kind of jade slip is cumbersome to make, and the materials consumed are also amazing, and it is generally used when it comes to the inheritance of the top sect.

And judging from the energy that leaked out when you were tempted just now, there is a trace of ...... sealed in this extreme yin wood marrow Thunder source.

And there will inevitably be exercises or secret techniques that match this thunder source.

Hey, hey, hey...... You're lucky again."

After speaking, Ling Lao laughed again and looked at Lin Fan with his strange eyes.

Lin Fan was uncomfortable when he was aiming at him, but he could guess a rough ...... Not a good thing anyway.

"Could it be that this thing is really broken?" Lin Fan asked tentatively.

A smile appeared in Ling Lao's slightly narrowed eyes, and his smile was extremely bright.

"Who said it's broken, although it's too old, this exercise should be intact."

"But if you want to cultivate ......."

Ling Lao looked at Lin Fan and suddenly paused.

"It's up to you kid to be able to withstand ......."

Lin Fan was in a commotion for a while, not knowing what to do......

"Inheriting the secrets, of course, the exercises must be supplemented by the energy in them to cultivate.

And there is a trace of thunder source sealed here, the thunder source is not ordinary thunder, it is the origin of thunder and lightning, as long as there is energy to replenish it, it can continuously generate thunder and lightning.

This thunder source has been sealed in the Extreme Yin Wood Marrow for 10,000 years, and it has consumed a lot of energy, and it has not been replenished, and now it is weak.

Can...... No matter how weak it is...... It's still a thunder source, although there is no intelligence, but there is still a violent thunder and lightning energy, and you will be numb when you leak a trace of electricity, if it all enters your body...... Imagine for yourself."

"Forehead ......"

Hearing this, Lin Fan's whole body trembled, and the crispy and numb feeling was really sour, but it had to be magnified dozens or hundreds of times...... Ling Lao is right, if you don't change the coke, you have to turn it into roast chicken......

But this also shows that Lei Yuan is extraordinary, and the power of the exercises that need the assistance of Lei Yuan to practice can be imagined.

"Elder Ling, is this thunder source very rare", Lin Fan asked solemnly.

Elder Ling knew Lin Fan's intentions, and he also nodded solemnly and replied.

"Not only is it rare, but the vitality of heaven and earth is divided into five elements, metal, wood, water, fire, and earth, and the five kinds of vitality are mutually reinforcing.

The energy of all things is the mutation or evolution of these five kinds of vitality, although the thunder and lightning attribute is not in the five elements, but it is born from the mutation of the wood attribute, so it can be stored and sealed with the extreme yin wood pith.

And the conditions for the generation of this lightning source are very harsh.

In ancient times, there was a "Thunder Island" on the "Endless Sea", and the thunderclouds on the island were shrouded all year round, and the island was baptized by thunder every day for millions of years.

There are often top human masters who go to the island to collect thunder sources in order to cultivate the thunder system exercises, but even the top masters are nine deaths and a lifetime, and it can only be harvested for thousands of years."

Hearing this, Lin Fan had a judgment in his heart, whether it was the "Inheritance Secret Slip" or the "Thunder Source", it was something that could be met but not sought, since he was fortunate enough to get it, it was his own opportunity, and what the cultivator was fighting for was the resource, and what he was asking for was this opportunity.

Now that this opportunity has come, what can be done even if it is more violent.

The path of cultivation is never smooth and comfortable, and there will be high returns at high risk, since you want to pursue the ultimate in martial arts, then such risks are bound to be few.

Sailing against the current, if you don't advance, you will retreat.

After thinking about it, Lin Fan took a deep breath and slowly exhaled it, then looked up at Ling Lao and said firmly.

"That's it, if you don't succeed, you will be benevolent."

......

To be precise, if it is not successful, it will become "charcoal". Ling Lao corrected him.
