This secret method was obtained by his master Thorn Dragon by accidentally exploring the ruins of an ancient immortal, and it was an ancient thaumaturgy of unknown quality.

This secret method can only be practiced by those who have awakened the Thunder Spirit Root in the bloodline.

And on the Spiritual Continent, Lei Linggen is very rare and rare.

After the Thorn Dragon obtained this secret method, he had always thought about accepting a person with a thunder spirit root as a disciple.

However, it has not been possible.

It wasn't until he stumbled upon Su Jian that he faintly felt a trace of Lei Linggen's breath from the latter's body.

Therefore, after he saw Su Jian, he accepted him as an apprentice without any hesitation.

It is said that this Nine Heavens Thunder Gang Scroll is divided into two parts: mental method and fighting technique.

The Mental Method section consists of two subjects.

One is the heart thunder technique, as long as you awaken the thunder spirit root, you can practice, introduce the spiritual energy into the body, and after the transformation of the thunder spirit root, turn into the thunder gang true qi and store it in the dantian.

This method is relatively gentle, safer, and less prone to errors, but the efficiency is slower.

Another mental method is called lightning channeling, which directly connects the power of thunder and lightning in nature to strengthen itself, the means are simple and crude, but there are some risks, and one will be hacked to death if you are not careful. But if it's successful, efficiency is a bargain. This mental method is only tried by a martial artist of the level of the Heaven Level.

In terms of fighting skills, there are two major tricks.

One is a thunderous knife, which induces Lei Gang's true qi to make a desperate knife, and it is a knife that is the most rigid and fierce, and it is a single-attack type of fighting skill.

Another trick is called Thunder Nine Days, which is claimed to be able to summon 3,000 thunderbolts to bombard nine heavens and ten lands between one move, which is a very fierce group attack and killing move.

It's just that the Lei Gang True Qi consumed by this move is a bit huge, and ordinary martial artists can't bear it, and only heaven-level martial artists can barely use it.

Anyway, in Su Jian's current situation, he majored in Heart Thunder Technique and Thunder Sword.

And these two exercises are very mysterious.

Su Jian spent four years to comprehend, and it was barely at the level of entry.

A quiet night.

Next.

As soon as the sky dawned, Su Jian walked down the small hill.

Then, he began a new day of demon slaying career.

kill

kill

kill

In half a day, he killed more than a dozen monsters such as coyotes and wild dogs.

At this time, the sun is at noon, and the sun is a little scorching.

Su Jian has been fighting with the demon beast for so long, although he has not shed blood, but he has shed a lot of sweat, and he is inevitably a little tired.

So, when he saw an unknown tree in front of him, he rode over.

He was going to rest for a while.

"Gotta got"

However, at this moment, a strange sound suddenly came to his ears.

"Well, this sound looks like a herd of wild horses galloping by."

Su Jian couldn't help but be stunned, so he turned his head to look at the left rear where the voice came.

At that moment, he could vaguely see a large herd of bison running for their lives on the horizon in the distance.

The hooves were trampled wildly, and the sound was so loud that it was like an earthquake.

"Hmm, a herd of panicked bison, it seems that something terrible is chasing them"

Su Jian muttered thoughtfully.

So, he deliberately searched for it.

Then he found a clue.

"There seems to be a monster in the herd that is super fast, and its figure is as fluttering as a white cloud, it must be the cloud leopard."

Su Jian thought of this.

At that moment, he couldn't help but get excited.

In fact, it was he who guessed correctly.

There was indeed a moire leopard walking among the herds, waiting for an opportunity to hunt bison for lunch.

This leopard has some cloud-like patterns on its body, and it runs extremely fast, looking like a fluctuating cloud from a distance.

"It's really fast"

"With such a speed, how can I kill it if I can't keep up?"

"Maybe when it stops eating, I'll have a chance to approach it and sneak attack."

"Well, that's it, I'll sit on the mountain and watch the tiger fight, and when it hunts a bison and stops to eat, I'll sneak up on it and kill it."

After thinking about it quickly in Su Jianyu's heart.

And he rode his horse to the herd of wild cattle.

It's not a lot of work.

And he approached the herd of bison.

He stopped when he was still a stone's throw away.

Then, just watch from the wall.

"Moo"

At that moment, I heard a terrible cry coming from the herd.

It seems that some hapless bison was culled.

Su Jian got closer, and he could see it clearly.

When he saw the moire leopard, he bit the neck of a brown bison with his mouth, and the blood flowed profusely.

As soon as the bison fell to the ground, it quickly stopped moving.

It seems that he was bitten to death directly.

The other buffalo fled in fear and soon went away.

The cloud-patterned leopard glanced up at Su Jian, and then lowered his head and began to enjoy his lunch.

He actually regarded Su Jian as if he were air.

It seems that it looks down on Su Jian, thinking that a mere human kid poses no threat to it.

On the contrary, it thinks that this human boy really doesn't know whether to live or die, and even stands there stupidly, doesn't it really think that it doesn't eat human flesh?

At that time, it had already decided to eat the wild bull that had arrived in its mouth, and then it would eat the human boy.

"Hey Feiyu, Lingyun, look at that side, there is a kid there who seems to be stupid by that cloud-patterned leopard, and he is motionless. ”

"It's really said that the man rode a very good horse, and he looked very rich, and I don't know what it came from."

"Ziqing, Feiyu, let's not care what the kid is from, let's take advantage of the fact that the cloud leopard is eating, let's seize this opportunity to hurry up and attack it." Otherwise, when it is full, I am afraid that it will run faster, and if I want to catch up with it at that time, I am afraid that there will be some difficulties. ”

"That's right, then let's work together to hunt that cloud leopard first."

Su Jian's physical strength recovered somewhat.

And by this time, it was getting dark.

He pondered for a while, thinking that this small hill was the territory of the iron-headed mad lion, and other demon beasts generally did not dare to approach it easily, which could be regarded as a relatively safe place.

So, he decided to spend the night in this place.

At that moment, he got up first, settled the horse, and then climbed to the top of the hill.

He stood, looked around, and saw no danger.

So, he sat down cross-legged, and directly entered the cultivation state, running the Heart Thunder Technique to cultivate.

In other words, what he is cultivating now is a supreme secret method called the Nine Heavens Thunder Gang Scroll.
