After getting the Seven Tribulations Lightning Strike Wood, Su Fan didn't have the heart to look at the next lot.

He couldn't wait to run to Shizun's cave mansion immediately and beg the old man to help him refine a thunder-based flying sword.

Don't look at the old man's lack of a good face when he sees him on weekdays, but although he has seen it through, the old man is a hard-mouthed and soft-hearted person, every time Su Fan goes to beg him, he doesn't see him not agreeing.

Su Fan drove the Yin Feng Boat to the Master's Cave Mansion and stood respectfully outside the main building.

"Master, the disciple asks to see ......"

"Come in ......"

Seeing Su Fan, the old man was not used to anything wrong at all, and he split his head and covered his face.

"If you don't cultivate well, what are you running to me every day......

Su Fan was speechless for a moment, when did I run to you every day.

But how dare he talk back, and take out the Seven Tribulations Lightning Strike Wood from the Na Ring.

"Master, look at this ......"

The old man took it impatiently, looked at it carefully, and was stunned for a moment.

"Lightning strikes wood, the ...... of several catastrophes"

"Seven Tribulations, I bought ...... at the auction in Canggu City"

"How much did it take?"

"Twenty-six Thousand Spiritual ......"

The old man shook his head with emotion, and picked up the lightning strike wood again to look at it.

"The quality is good, you can be considered a bargain, we don't have many Demon Gate Lei Xiu, if this thing is in the Immortal Sect, you can't take it without 100,000 spirits."

Su Fan was shocked when he heard this, this thing was actually worth 100,000 spirits.

The old man laughed and said, "Show me this thing, what are you going to do......"

"Master, I want to ask you to help me refine a flying sword."

"Flying Sword, what do you want that thing to do......

Su Fan hesitated, but still told Lao Ye about his sword technique.

"I said, how can you have the shadow of sword cultivation in your kid's swordsmanship, it turns out that there is such an opportunity."

After he finished speaking, he glanced at Su Fan and asked suspiciously.

"You're from Ganzhou?"

"When the disciple was doing loose cultivation, he stayed in Yongzhou for a while."

"I said, how do you know those sword maniacs......"

"Okay, I agreed, but the thunder-based flying sword, I also refined it for the first time, if something goes wrong, then it's no wonder to me."

"Master, even though you are refining, how dare the disciple blame ......"

"Hmm...... Go ahead, I'll have to think about it......"

Su Fan left Shizun's cave mansion, and finally breathed a sigh of relief, the thunder flying sword finally had fallen.

He returned to the cave mansion, sat cross-legged on the futon, and took out the jade slip of the "Zixiao Running Thunder Sword Technique" and put it on his forehead.

It took a long time for him to put down the jade slip.

It seems that it is not so easy to learn this sword technique.

Before cultivating the sword technique, you not only need a thunder-based flying sword, but also use thunder to raise the sword.

According to the sword technique, the flying sword is finally placed in the thunder pool to nourish, so that the thunder flying sword can absorb enough thunder and lightning before it can practice the sword technique.

Let him find Lei Chi somewhere.

Thunder pools are not available everywhere, and they need natural lightning guidance places, which are naturally formed after years of sedimentation.

Even many sects with the inheritance of the thunder lineage may not have a thunder pool.

Suddenly, Su Fan's eyes lit up.

I don't know if the thunder in the Dao species in the body can replace the effect of the thunder pool.

Forget it, don't want to.

It's useless to think about anything now, let's wait until the master finishes refining.

A month later, Su Fan came to Shizun's cave again.

The old man was already standing outside the bamboo building, waiting for him, and when he saw Su Fan coming, he took out a palm-length pitch-black flying sword from the ring.

"The sword has been refined, look at it."

Although the old man said this, there was a smug look in his eyes.

Su Fan knew that this matter was stable, and the flying sword should have been successfully refined.

He took the flying sword from Shizun's hand and looked at it carefully, his heart was excited.

"The Best Flying Sword ......"

The old man smiled and stroked the goatee on his chin, with a smug expression on his face.

"Look at your useless appearance, it's just a flying sword, and it's okay to practice......"

Su Fan said in his heart, you can pull it down.

Your old man's smug beard is about to rise.

After receiving the teacher's examination, he couldn't wait to return to the cave.

Sitting cross-legged on the futon, he took out the flying sword from the ring and looked at it lovingly.

The small sword was only palm-long, and its entire body was as black as ink, flashing with an ancient glow.

Let's call it "Ben Thunder Sword".

Su Fan began to refine the flying sword according to the method in the sword technique, and laid his own divine sense brand.

After refining the flying sword, Su Fan could clearly feel a wisp of his divine sense in the flying sword.

He took a deep breath and looked at it.

Su Fan's eyes froze, and the Dao seed in his body spun violently.

At this moment, countless purple currents overflowed from the Dao seed in his body, which kept circulating in Su Fan's body.

"Whoosh......"

Suddenly, the flying sword turned into a thin streamer, and it suddenly sank into his heart.

Su Fan was completely defenseless, and he only felt that his heart was numb, as if something had penetrated into his body.

With a "buzz", he instantly fell into a state of distraction.

Su Fan hurriedly stared at him, and instantly regained his clarity.

As soon as his consciousness swept away, he saw that the flying sword was levitating in the Dao Seed, surrounded by countless restless purple currents and scorching anode heat.

Su Fan breathed a sigh of relief, the Dao Seed was really as he thought, replacing the effect of the Thunder Pool.

It can also be said that the Dao species has the characteristics of a thunder pool.

Let the "Ben Thunder Sword" slowly nourish in the Dao Seed, the longer the nourishment, the higher the level of the flying sword in the future.

Su Fan's heart moved, if he received the heavenly thunder a few more times, would it improve the quality of the purple thunder in the Dao seed.

Thinking of this, Su Fan's mind moved.

Or else, try it......

Try it, just try it......

A few days later, Su Fan sat on a mountain outside the Mountain Gate Great Array, looking up at the overcast sky.

"Lao Tzu is the life of a thunderbolt......"

Su Fan sighed and began to run the first exercise of the "Heavenly Demon Holy Body Technique".

Ten minutes later, Su Fan was dumbfounded by thunder.

Although the second layer has been consummated, the physical body is no longer the same, and even the skin has not broken after the thunder strikes.

But there is no less sin to be suffered.

Tineema hurts.

Not to mention, the effect is really good, and the purple thunder in the Dao Seed is obviously a lot richer.

Then come on, Su Fan doesn't care anymore.

Come on, let the thunder and lightning come more violently.

A few days later, Su Fan returned to the cave mansion, he had been struck by lightning in the past few days, and he was almost unconscious.

However, the quality of the purple thunder within the Dao Seed has been greatly improved, and it has evolved from light purple to dark purple.

And there is also a lot of potential to continue to improve the quality of the Thunder.

It's just that the weather is clear, and it can't lead to thunder.

Besides, Su Fan is already about to be cleaved stupidly, so he has to rest for a few days.

However, after a few days, Su Fan felt that his divine sense seemed to be stronger.

The physical body has not made much progress, but the impurities in the body, erysipelas, have been tempered again.

Su Fan's current body has no impurities, and it is as pure as glass.
