When he came to Tianzhou this time, Shi Xiaole's first stop was Mingyuan Town in the Fengyang Domain, so he also stored Qingfeng nearby. There is only one master in Mingyuan Town, Zong Xingnan, and with Qingfeng's cleverness, there should be no accident.

Sure enough, there was a whistle outside Mingyuan Town, and after a while, a tall divine horse, like an amber horse, flew over, arching Shi Xiaole's neck affectionately, and did not forget to lick it with his tongue.

After not seeing him for more than half a year, Shi Xiaole keenly noticed that Qingfeng's speed seemed to be a lot faster, and the leap just now was almost not weaker than that of a high-level martial artist in the Longguan Realm.

"Xiaofeng, can you sense this breath?"

Taking out a syllabite, Shi Xiaole asked. As the helmsman of the Anti-Demon Alliance, he has a fixed share of bassarite every month.

Boom.

Qingfeng tilted his head.

Having the heart to test its sensing range, Shi Xiaole put this Xuanjing stone within five hundred meters, one thousand meters, two thousand meters and other distances in turn, and to his surprise, it was easily found by Qingfeng.

Three thousand meters.

Four thousand meters.

5 thousand meters.

When the distance reached 10,000 meters, Qingfeng showed a hesitant look, but Shi Xiaole was already very satisfied.

It must be known that the shallowest spiritual veins are tens of thousands of meters underground, and because of the isolation of the soil, it will also lead to a great reduction in induction. Fortunately, the spiritual energy of the spiritual veins is far more abundant than a single sylvestite a hundred times and a thousand times.

At least it is far more convenient for Qingfeng to find the spiritual veins than himself.

In this way, a man and a horse ran aimlessly in the wilderness.

Qingfeng's endurance is terrifying, basically resting for an hour, he can run with all his strength for three hours in a row, probably knowing that the master is in a hurry, it tried its best, and in just one month's effort, it almost ran through a domain of mountains.

During this time, Shi Xiaole practiced martial arts on horseback, leaving only a distraction to perceive danger in the outside world.

Another month.

Qingfeng's excited shouts sounded in his ears.

Shi Xiaole woke up from his cultivation state: "Could it be that you found it?"

Qingfeng kept screaming, running back and forth around the uneven hillside, meaning something.

The long sword was unsheathed, Shi Xiaole's sword was united, turned into a sword light and pierced into the ground, rushing to a depth of thousands of meters at one time, Qingfeng hurriedly followed, not forgetting to hide the traces.

Sword moves in bursts.

One person and one horse continued to go deeper, but the soil became harder and harder, and the pressure was like countless iron plates squeezing towards Shi Xiaole, and there was a friction sound with the body guard.

The most terrifying thing is the temperature, when it comes to 10,000 meters underground, it exceeds more than 1,000 degrees, and ordinary people will turn into ashes in an instant when they come here.

Fifteen thousand kilometers.

20,000 meters.

When he came to 25,000 meters underground, Shi Xiaole could only dig tens of meters deep at a time, and just breaking through the underground pressure consumed more than half of his strength, and the temperature here reached an astonishing 3,000 degrees Celsius or more.

Even if the Venerable of the Dragon Pass Realm came here, there would be death and no life.

Qingfeng screamed, but strangely, its amber hair glowed slightly, as if it was isolated from the effects of pressure and temperature, and it was more calm than itself.

Sword after sword.

The excavation project became extremely difficult, and it also required a lot of time to rest, and after two hours, Shi Xiaole had only penetrated hundreds of meters, but only a pitiful thirty percent of his strength was left.

If he continues to consume, he is afraid that he will not be able to withstand the pressure and temperature, and the result will be evaporated.

Bang bang bang!

Seeing that the master was tired, Qingfeng volunteered, and kicked the ground with four hooves, although the efficiency was not as good as Shi Xiaole, but it was better to last. And taking this opportunity, Shi Xiaole desperately recovered his strength.

In this way, under the rotation of digging by one person and one horse, they successfully came to 30,000 meters underground.

"What a rich aura!"

Shi Xiaole was suddenly overjoyed.

It stands to reason that neither the spar nor the sun and moon spar can withstand the temperature underground, but the world is so peculiar. It is said that the periphery of each spiritual vein is wrapped with a special aura, making it safe and sound.

And the 'aura' required to cast a medium-grade spirit sword is precisely this breath.

Keeping his skills at fifty percent, Shi Xiaole made persistent efforts, and finally dug up the spiritual vein two days later.

Rumble!

The majestic and gratuitous aura came to his face, and it actually shook away the terrifying heat around him in an instant, and penetrated into Shi Xiaole's pores, making him so comfortable that he almost groaned.

"It's still a medium-sized Xuanjing spirit vein!"

The spiritual veins are divided into five types: non-flowing spiritual veins, small spiritual veins, medium-sized spiritual veins, large spiritual veins, and super-large spiritual veins.

It is not a spiritual vein, in fact, it is not a spiritual vein, it is just a pile of scattered spar aggregates, which are the easiest to find, and it is also the largest source of spars circulating in the rivers and lakes at present.

When it comes to small spirit veins, you need to cooperate with the master of the Dotting Stone.

As far as Shi Xiaole knew, a small Xuanjing Stone Spirit Vein could completely make hundreds of Xuanqi Realm martial artists break through to the Spirit Pass Realm martial arts, while a medium-sized spiritual vein was more than ten times larger.

No wonder the imperial court controls it so strictly.

"Originally, the grasp of casting a medium-grade spirit sword was less than fifty percent, but since it was a medium-sized spirit vein, it could give it a fight. ”

Without wasting time, Shi Xiaole immediately took out the Cloud Tiger Stick, the Farewell Staff, and a few other low-grade spirit swords obtained in the Blood Battle Original.

Snort.

At a high temperature of nearly 5,000 degrees Celsius, the lower grade spirit soldiers began to melt, and because there was no sword fan, Shi Xiaole could only condense the gang qi, and then used the gang qi as a hammer, and began to beat and smelt according to the casting method of the middle grade spirit soldiers.

He didn't rush to take out the Shining Star Stone, there was only one chance, and before that, he had to be familiar with the casting method of the medium-grade spirit soldier.

Bell!

Since this day, in the 30,000-meter underground, there has been a crisp sound of striking iron every moment, and wisps of sword qi have also come from nothing, spreading to all directions with the sound.

The aura outside the medium-sized spiritual vein entered the weapon forged by Shi Xiaole with a trajectory that was difficult to capture.

In the first few days, Shi Xiaole's failure rate was very high.

Dozens of darts made from the essence of the cloud tiger stick were all blown up.

After that, there is the parting stick, and the success rate reaches 10%. Of course, the darts made are by no means medium-grade spirit soldiers, because the materials are not up to standard, at most they are low-grade spirit soldiers.

A month passed.

There are only three lower grade spirit swords left, and Shi Xiaole's success rate has increased to thirty percent.

If there was a swordsmith here, he would definitely be amazed at Shi Xiaole's progress speed. Generally speaking, no matter how talented a swordsmith is, it will take half a year to increase the success rate by 20%.

"The Sword Dao of the Wind has really improved. ”

In addition to the improvement of the level of sword casting, what surprised Shi Xiaole the most was that the Wind Sword Dao in the early stage of Sicheng had obviously improved, and it seemed that while he was hammering weapons, he was also slowly eliminating the dross in the Wind Sword Dao.

What Shi Xiaole didn't know was that some Shenguan Realm swordsmen who had mastered the art of sword casting would also choose sword casting to precipitate and accumulate after encountering bottlenecks.

It's a pity that the time and energy they consume are dozens of times that of Shi Xiaole, and the results they achieve are definitely not as good as his ideals.

"At this rate, at most two or three months, the success rate should reach more than 70%. ”

Shi Xiaole smiled excitedly and continued to devote himself to forging the sword.

In the depths of the endless earth, pitch black and calm, suddenly two white lights exploded like lightning, revealing terrifying anger and hideousness.

Shout!

The wind split the heat wave and swept towards Shi Xiaole.

"Who?"

Shi Xiaole couldn't help but be surprised, there was no sign of the other party's appearance, of course, it was because of his mental concentration, but even so, the hidden kung fu was also first-class.

"A breeze through the court!"

Using his arm as a sword, Shi Xiaole swung out a sword aura.

Boast!

Under the action of underground pressure and temperature, the power of the sword qi was reduced by hundreds of times, and when it collided with the qi energy, it made a dull sound like a drum.

With his eyes like a lamp, Shi Xiaole saw the person coming clearly.

It wasn't a human, it was an ape with snow-white hair and a body like a child!

"Mutant animals?"

In an instant, Shi Xiaole connected the white ape with Qingfeng and the white jade tiger he met in Peony Town.

Roar!

Without giving Shi Xiaole time to think, the white ape jumped like lightning and rushed from the other end of the spiritual vein.

Judging from its familiarity with the terrain, it should have discovered this place very early, and it may even have regarded the medium-sized spirit veins that were useless to it as its private property, so it launched a surprise attack on Shi Xiaole.

"Blade of the Wind!"

The white ape was easily knocked out by the sword qi, but the sword qi that could make the four top earth immortals hate did not leave any traces on its body.

Seeing that he couldn't even get close, the fierceness in the white ape's eyes was even worse, and a threatening angry cry came out of his mouth.

Damn human, although I can't beat you, my mother is transforming, and when she completes her transformation, she will teach you to die without a place to be buried!

With a thick unwillingness, the white ape disappeared into the ground.

"How many mutated animals are there in the world, if they can be organized, they will be invincible in the world to find spiritual veins. ”

Even Shi Xiaole was amused by his whim, and after laughing, the extraterrestrial stone of the Bloody Battle Plain suddenly sounded, as well as the inscription left by the immortal scholar of Peony Town.

Wait, the stone bed of the Hundred Flowers Cave is also from outside the sky, could it be ......

"Well, the future will come to know. ”

didn't take the white ape to heart, Shi Xiaole continued to forge swords, and sometimes Qingfeng would come down, but it was afraid of disturbing its master, and it thought that the underground environment was too bad, so it stayed on the ground most of the time.

Time slipped by in Shi Xiaole's increasingly refined sword-forging skills.
