"This is the Heavenly Thunder Bamboo?"

Yu Xing frowned, because the bamboo itself could not feel a trace of energy fluctuations at all.

"Don't worry, senior."

The woman saw Yu Xing's doubts, and quickly turned over her hand and took out a dagger, and slashed it towards the bamboo body. The moment the blade touched, a slender arc of electricity appeared on the surface of the bamboo, and the dagger immediately bounced off.

Yu Xing nodded and put away the Heavenly Thunder Bamboo.

Back in his cave, he didn't do anything else, but immediately consulted the many books he had stored.

Finally found the cultivation method of the Heavenly Thunder Bamboo from a jade slip, and then Yu Xing transplanted this bamboo to the medicine garden according to the gourd painting.

Heavenly Thunder Bamboo is divided into grades.

The Heavenly Thunder Bamboo under 2,000 years old can only release ordinary white thunderbolts, and over 5,000 years old, the thunderbolts will turn blue, and the power will be much greater.

And when the thunder bamboo reaches more than 10,000 years, the thunder and lightning will turn into a pale gold color. At this time, the power of thunder and lightning will reach an unimaginable level, and it will have various restraint effects on various evil spells and magic skills, which is called "the thunder of warding off evil spirits" by immortal cultivators.

And the Heavenly Thunder Bamboo in his hand is obviously just a white thunder bamboo.

But he doesn't care about it, he has a small green bottle, which can be cultivated slowly, and it will be cultivated into a golden thunder bamboo, and it will be of much use to himself at that time.

Cultivating spiritual objects that last more than 10,000 years is very time-consuming.

In the past, the remaining punishment was only at the level of cultivating the medicine for one or two thousand years, and it could be used for alchemy. But for the sake of this heavenly thunder bamboo, he did not go out for two full months.

The small green liquor that will be spawned is all used on the spawning Tianlei Bamboo.

Nowadays, the bamboo that used to be more than two inches long is now completely different.

Not only did it grow to a height of about a foot, but it was also covered in emerald green, covered with a faint glow.

Yu Xing looked at it intently for a while, flipped it with one hand, and a small sword magic weapon appeared in his hand, and then the small sword turned into a white light and shot directly at this bamboo.

A pale golden arc of lightning emanated from the thunder bamboo that day without warning.

There was a muffled sound, and after the white light was hit by this pale golden arc, it turned into a curling green smoke visible to the naked eye, and disappeared without a trace.

"Yes, it's already a 10,000-year-old golden thunder bamboo."

These days, the rest of the punishment was not wasted, and the seventy-two immortal swords in his hands were re-refined. is also a loss of his wealth, and he is called an outsider, I am afraid that he does not have such a large financial resource at all.

"Cultivate it for a while." A golden thunder bamboo, still not enough to satisfy the remaining sentence, what he thought was that among the seventy-two immortal swords, all of them would be integrated into the golden thunder bamboo, and the power of the sword array would definitely increase exponentially.

A year later.

"Iron slave, help me protect the Dharma."

Before Yu Xing entered the secret room, he gave a word to the iron slave.

Tie Nu nodded, now he is also a strong man in the later stage of the Yudan, and Yu Xing has also begun to think about helping Tie Nu get married.

After entering the secret room, Yu Xing conveniently arranged a small formation outside that he had comprehended over the years.

This formation has no other effect, but it can effectively mask the fluctuations of aura. It is just right for the rest of the punishment to be used when refining magic weapons.

He didn't think that when he was halfway through the refining of the treasure, he was spied on by others. Then, he meditated quietly for three days and three nights in the Yu Punishment Secret Room to keep his spiritual mana completely in the best state before he began to refine the magic weapon.

For the refining of the sword array this time, Yu Xing attaches great importance to it.

Yu Xing waved his hand, and snatched out more than a dozen precious wooden boxes from the storage bag, and in each box, there was a foot-long Heavenly Thunder Bamboo.

Today's scene, if it is seen by others, will definitely shock the jaw of the world.

Yu Xing solemnly pinched a legal decision, and the glow on his face flowed, and a layer of blue light gradually appeared.

As the blue light became thicker and thicker, Yu Xing opened his mouth, and a slender silky cyan pill fire blurted out, spraying right on the heavenly thunder bamboo in front of him.

With a "crackling" sound, a pale golden arc appeared on the surface of the bamboo, and it unceremoniously isolated the Danhuo, preventing it from getting close to half a step.

Seeing this scene, Yu Xing's eyes flashed, and the cyan pill fire immediately became a little stronger, and in an instant, the arc and the bamboo body were wrapped in the green fire, and the long refining process began.

Just refining these twelve golden thunder bamboos took a month to refine.

Yu Xing casually took a pill that replenished mana and continued to close his eyes. A green glow came out of his body.

As soon as these rays appeared, the spirit stones inlaid on the magic circle emitted a dazzling light, and the entire magic circle began to operate in a low sound.

From the storage bag of Yu Xing, seventy-two fairy swords, comparable to magic weapons, swept out and disappeared into the pillar of light.

Suddenly, those pillars of light seemed to come to life, and began to flicker and change colors.

A strange scene appeared, and after the countless changes of those pillars of light, the colors gradually converged. It was followed by the green liquid refined from the twelve golden thunder bamboos.

It was divided into seventy-two parts, and it also submerged in the pillar of light.

In an instant, seventy-two fiery red pillars of light burst into flames. Seventy-two green liquid flying swords officially appeared in the pillars of fire.

If Yu Xing hadn't been for the Yuanying Monk, I'm afraid he would have been unable to bear it a long time ago.

One-time refining, seventy-two magic weapons, who in the world dares to do this?

"Hoo ......"

It took a full day and a night for these flying swords to be refined.

Chu Mo breathed a sigh of relief, looking at the seventy-two small swords nearby, he suddenly exerted his teeth slightly, and the tip of his tongue was about to break a little, and a mouthful of essence blood spurted out, condensing into an egg-sized blood mass in front of him.

Then, under the manipulation of Yu Xing, the blood mass dripped several drops into each sword embryo.

As soon as the essence blood came into contact with the liquid flying sword, it immediately quickly escaped into it, disappearing without a trace.

Seventy-two flying swords with silver light quickly trembled. Chu Mo waved his hand and put it all into the storage bag, and the current sword formation was really useful to him.

In the future, if the enemy is the Yuanying Monk, the other party is estimated to be surprised.

"It's been three years, it's time for me to go back." Yu Xing muttered, and a shadow appeared in his mind, Nangong Wan, he still couldn't let go of the other party.

Before, he was just a monk of the Yudan, and it was useless to stay in Tiannan.

Now that he has become a Yuanying, and his natal magic weapon has been improved, he is confident that Yuanying can also fight in the later stage, so he also moved his mind to go back.

Yu Xing walked out of the secret room, and the iron slave suddenly walked over respectfully.

"Master, there is some news that you may be interested in."

With the enhancement of cultivation, the spiritual wisdom of the iron slave has become more and more complete.
