Wild Wind Hammer Technique

Tian Hao let go of his restraints, using the tens of thousands of catties of coal collected by the Mount Hua Sect to produce entirely coking coal. At the same time, he fired a batch of carbon bricks. Though the quantity was small, it was enough to build the inner furnace. As for the outer furnace, ordinary clay refractory bricks would suffice.

"Can this strange fire furnace really smelt Black Iron?"

Yue Lingshan inspected the bizarre-looking furnace before her, genuinely failing to understand how this contraption could possibly smelt Black Iron.

She had indeed seen that fire furnace in the cave before, but she hadn't known its internal structure at the time. This time, she watched with her own eyes as Tian Hao built the furnace brick by brick; the inner construction was exceedingly complex and peculiar.

Ignoring the young girl's doubts, Tian Hao checked the fire furnace once more. Confirming everything was correct, he finally looked toward the cheap master standing beside him.

"Master, has the ventilation shaft been dug out?"

This karst cave was, after all, located deep inside Mount Hua, and ventilation was a major problem.

Once the fire furnace operated for a long time, it would inevitably generate immense heat. If the ventilation was inadequate, the entire cave would become unbearably stuffy.

Most importantly, ordinary combustion required air as support, and only at the most critical moments would they switch to the produced oxygen for oxygen-enriched combustion to further raise the temperature.

Therefore, ventilation was of the utmost importance!

"There was originally a ventilation shaft in this cave that could form a convection current with the entrance. Your martial uncles and granduncles and I expanded it over the past few days. Coupled with those pedal-powered bellows you designed, it's more than enough to ensure the air inside the cave flows smoothly."

Stroke his long beard, Yue Buqun had long since completed the foundational work according to his disciple's demands, leaving only the opening of the furnace to forge the Black Iron.

"Open the furnace!"

Taking a deep breath, Tian Hao gave the order, and immediately a martial uncle stepped forward to ignite the fire furnace. Li Buli and the others also gathered around to assist.

The forging of Black Iron had to be kept strictly confidential. Even among the current second-generation disciples of the Mount Hua Sect, only Tian Hao and Yue Lingshan were present; aside from them, there was no one else, ensuring the highest level of secrecy.

In no time, the fire furnace heated up, and everyone could feel a wave of scorching heat even while standing away from the stove.

"Stop the bellows, close intake vent number one, open intake vent number two."

Seeing that the temperature had risen sufficiently, Tian Hao signaled for intake vent number two to be opened.

The middle-aged man operating the bellows stopped, closed the exhaust vent on the bellows, and opened the intake vent marked with a two.

Although the bellows had stopped, the flames inside the furnace continued to burn fiercely, as if an invisible wind was blowing on them.

"You can control the wind?"

Yue Lingshan felt a great sense of wonder. Although she had seen it many times in that cave before, this was the first time she had witnessed the entire process, and she truly failed to understand the mystery within.

"Hot air is lighter than cold air. Once the fire furnace heats up and generates hot air, it rises through the upper exhaust vent, creating a suction force at the lower intake vent."

Dropping a casual explanation, Tian Hao was hardly unfamiliar with this sort of thing.

He was a rural native, and in the countryside, there was a type of cooking stove known as a suction stove that could automatically draw in air without the need for bellows, keeping the flames burning fiercely.

Back then, he had simply rigged up a suction stove in that cave to replace human labor in pulling the bellows; otherwise, there was no way he could have carried out the forging all by himself.

"It seems somewhat similar to a Kongming Lantern."

An old man said thoughtfully, feeling that the principle was somewhat similar to the flying Kongming Lantern.

Prompted by this remark, the others also had a sudden flash of understanding.

They had heard of Kongming Lanterns, which could fly high into the sky, and ordinary candlelight flames always pointed upward as well. They hadn't understood it before, but now they finally figured it out.

After figuring it out, everyone could not help but cast gazes of admiration toward Tian Hao.

Although the underlying principle seemed simple, being able to apply knowledge flexibly was a sign of great wisdom.

"Close intake vent number two, open intake vent number three."

After waiting for a moment, Tian Hao issued another order, switching to intake vent number three.

The cold air drawn in through intake vent number three first passed through pipes set over the fire furnace to be heated into hot air, and was then conveyed into the interior of the fire furnace.

Burning with cold air consumed a portion of the heat itself, but the heat consumed by hot air was much lower. Thus, the temperature of the flames in the furnace was further increased.

Tian Hao then placed several pieces of meteoric iron ingots into the core of the flames to be roasted until they turned a dark red.

"Close intake vent number three, open intake vent number four, slowly press down the leather bag."

Issuing another command, a middle-aged man not far away slowly pressed down on the leather bag beside him.

That was a genuine leather bag, specially obtained by having Old Yue find some cattle, shatter their beef bones, and extract the beef and bones bit by bit to ensure the integrity of the cattle hide to the maximum extent. Then, all the openings were sealed with glue and thread to serve as a sealed bag for storing oxygen.

There was no help for it; conditions were limited, and they could only do it this way.

As pure oxygen was introduced into the fire furnace, fueled by the pure oxygen combustion, the flame temperature surged sharply once more. In a short while, several pieces of meteoric iron ingots were burned to a bright golden color.

"It's done, it really is done!"

Peering through the observation hole to see the meteoric iron inside turn a bright golden color, everyone was stirred beyond control.

Earlier, when Yue Buqun said Tian Hao could refine meteoric iron into Black Iron, they hadn't quite believed it. Never did they expect him to actually pull it off; at the very least, the temperature was sufficient now.

"Fetch the iron!"

Wielding a large meteoric iron hammer, Tian Hao gave the order once more.

Immediately, someone used iron tongs forged from meteoric iron to pull out a meteoric iron ingot.

"Wild Wind Hammer Technique!"

With a loud roar, the Great Accomplishment realm Embracing the Origin Inner Force surged, swinging the meteoric iron hammer in his hand down with a heavy blow.

"Clang!"

A deafening sound reverberated outward. Utilizing the rebound force to swing the hammer head back up, his body spun in a circle, driving the iron hammer to smash down fiercely once more.

"Clang, clang, clang..."

Each hammer blow was heavier than the last, with both force and inner force continuously accumulating.

That was right, what Tian Hao was using was none other than the peerless martial art of a certain Tang family, the Wild Wind Hammer Technique. However, having nowhere to learn it covertly, he could only create a knockoff version.

Back when he realized the importance of Black Iron, he had already made plans for his future.

Although martial arts was his primary occupation, he also had to develop a secondary trade. Back then, he chose blacksmithing as his secondary trade.

And speaking of blacksmiths, one could not help but think of a certain Third Young Master, and thinking of Third Young Master, one could not help but think of that set of Wild Wind Hammer Technique.

That technique was inherently a method of borrowing force to strike with force, continuously accumulating strength through the power of rebound.

Therefore, he had specifically requested his master and mistress to search for martial arts capable of borrowing force to strike with force whenever they went out, ultimately obtaining the Eagle Claw Stele-Smashing Hand.

Ever since he cultivated the Eagle Claw Stele-Smashing Hand to the Great Accomplishment realm, he had been pondering over a bootleg version of the Wild Wind Hammer Technique, and finally, he managed to puzzle out a tiny bit of its mysteries.

Especially after overlaying Aunt Dongfang's Innate Attribute, his comprehension ability doubled, and he finally rudely concocted this knockoff version of the Wild Wind Hammer Technique.

Yue Buqun and the others also saw that something was amiss, their expressions shifting between astonishment and suspicion.

Without even looking, the steadily escalating sound alone let them know that the striking force was constantly increasing. Yet this clearly already exceeded Tian Hao's own physical strength limit.

How was he erupting with a force that surpassed his own limits?

Could he be using some kind of desperate secret technique, or had he taken some sort of drug?

At this thought, Yue Buqun and the others grew anxious.

One had to know that Tian Hao was an peerless genius capable of independent epiphany with an immeasurable bright future. There was no need to ingest taboo drugs just for a tiny bit of Black Iron, ruining his future.

The losses outweighed the gains, truly the losses outweighed the gains!

"Don't disturb Hao'er, he's fine."

Stopping her anxious husband, Ning Zhongze's beautiful eyes flashed with brilliant ripples, and a vague suspicion formed in her heart.

If her guess proved true, then this disciple was simply too monstrous, almost comparable to the youth of Zhang Sanfeng, the True Martial Dao Venerable of Wudang.

His future was bound to be limitless!
