Tempering the Body with Spiritual Fire

Upon hearing this, the burly man breathed a sigh of relief. He was genuinely afraid that his martial uncle would take it seriously, otherwise his life would be much more difficult.

But when he heard that Li Yunfan actually wanted to use a room with strong earth fire to refine pills, he was greatly surprised.

Although he doesn't know how to refine pills, he has received many senior uncles who come here to refine pills. Each time, a room with stable earth fire is needed. Why is this senior uncle acting so strangely?

However, after the lesson he had just learned, he dared not ask any more questions, for fear of angering the other party.

"Yes, Uncle-Master! However, according to the rules, one low-grade spirit stone must be paid every three days for using earth fire. I wonder if Uncle-Master..." The big man first respectfully agreed, and then asked somewhat cautiously.

"I will naturally abide by the rules. Consider this mid-grade spirit stone as a deposit, and I will settle the account with low-grade spirit stones after I come out!" Li Yunfan took out a mid-grade spirit stone and threw it over before slowly saying.

"Please register my name, Master Uncle, so I can arrange a Fire-Earth House for you!" The burly man accepted the spirit stone, a smile immediately appearing on his face as he spoke respectfully.

After registering Li Yunfan, the burly man took out a token from his pocket, unlocked the restrictions on the giant gate, and respectfully invited him inside.

After passing through a black passage, a huge black hall, forty or fifty feet wide and more than ten feet high, suddenly appeared before them.

Around the hall, rows of white stone doors of the same size are neatly arranged, numbering more than thirty.

"Uncle-Master, this is where the Earth Fire Chamber is located. The closer you are to the underground, the stronger the earth fire becomes, but the less stable it is. Therefore, uncles-masters who come here to refine pills will choose rooms that are located at the top..." The big man respectfully introduced to Li Yunfan.

After speaking, she glanced cautiously at Li Yunfan, and seeing that his expression remained unchanged, she continued.

"If Martial Uncle desires a more intense subterranean fire, then it should be numbers one through seven, with number three being the most intense but also the most unstable!"

"Okay, then number three it is!" Li Yunfan nodded and said.

The burly man responded, then led Li Yunfan up the stairs to the third white door, took out his token and stuck it on the door, which opened automatically.

The entire house was only seven or eight zhang in size, with a round mound about one zhang wide in the middle. On its outer side, there were eight red dragon heads, facing the center of the mound. On each of the four walls, there was a gourd the size of a fist.

After explaining the layout and usage of the room to Li Yunfan, the burly man handed him a jade token and then respectfully took his leave.

After the big man left, Li Yunfan closed the white gate, walked to the round mound, and began to examine the method of driving earth fire recorded on the side.

In just a short while, he had completely memorized the incantation. Then, he cast a spell to activate the dragon's head, and eight purple flames, each as thick as a chopstick, immediately burst forth from it, instantly filling the entire room with scorching heat.

Li Yunfan smiled slightly, cast a spell to shut it down again, and then sat down cross-legged about ten feet away from the round mound.

He didn't come here to refine pills, but to absorb the earth fire and cultivate the first stage of the Nine Revolutions Burning Heaven Technique!

"This earth fire, also known as the fire of the earth's lungs, is a spiritual fire that can only be born in the land of Xuan Yang. It is even more powerful than the innate true fire of a Foundation Establishment cultivator, making it perfect for my current cultivation level!"

After thinking it over, Li Yunfan took a deep breath, recalled the records of the Nine Revolutions Burning Heaven Technique on refining spiritual fire, and once again cast the spell to activate the dragon head.

Looking at the eight streams of violently surging purple flames, Li Yunfan's expression turned serious. He made a hand seal in front of his chest and then pointed a finger at the flames!

The eight purple flames instantly condensed into a purple fireball the size of a thumb above the round mound.

Looking at the condensed fireball, Li Yunfan's eyes showed a solemn expression, and then he actually opened his mouth and inhaled it into his body.

After the fireball entered his body, Li Yunfan quickly used his spiritual energy to tightly envelop it to prevent it from exploding inside his body.

Feeling the fireball safely resting in his dantian, Li Yunfan breathed a sigh of relief, but soon he regained his focus.

Because the infusion of spiritual fire into the body is only the first step; the subsequent tempering of the body with flames is the most dangerous part...

He gradually withdrew the spiritual energy that enveloped the fireball, and the scorching heat of the earth fire immediately emanated from his dantian, causing even the liquid spiritual energy within it to begin to boil.

Fortunately, the amount of earth fire he absorbed the first time was very small, and with his careful control, it did not explode.

Feeling the scorching heat from the fireball, Li Yunfan made a sudden decision and directly controlled his liquid spiritual energy to rush towards it. The earth fire was instantly ignited by the spiritual energy, suddenly expanding several times, and began to spread throughout his body along with the spiritual energy!

"ah!!"

Li Yunfan screamed in agony, his face contorting in pain!

At this moment, he felt as if the earth fire was constantly burning inside his body, as if it was going to burn his meridians, bones, and internal organs to ashes.

Suppressing the excruciating pain within his body, Li Yunfan began to circulate the Nine Revolutions Burning Heaven Technique, allowing the spiritual energy ignited by the earth fire to rapidly flow through his body...

Seven days later, Li Yunfan sat cross-legged on the ground, his whole body radiating a faint heat, like a newly lit furnace.

He exhaled a breath of warm air, slowly opened his eyes, and a successful smile appeared on his lips.

"Finally, the first step has been successfully taken. The next step is to repeat this process continuously until a trace of fire attribute appears in all my bones and muscles. Finally, I will refine the earth fire to complete the cultivation!"

However, the thought of the excruciating pain of being burned alive still made his eyes twitch involuntarily...

Take a deep breath, clear your mind of distractions, and begin condensing the fireball and absorbing it into your body once more.

A dozen days later, Li Yunfan successfully underwent his second spiritual fire tempering, and wisps of light red spiritual threads gradually appeared in his body's muscles and bones.

A month later, after completing the body tempering for the third time, the strands of spiritual energy on his bones had thickened.

……

And just like that, eleven months passed by unnoticed.

"Bang!"

On this day, a muffled sound suddenly emanated from the once quiet land of fire.

A moment later, several figures with gloomy faces emerged from behind the white stone door.

"Zhao Tianming, get over here!" one of the old men, who had a goatee, shouted angrily.

Seeing this, the others did not speak up to stop it; instead, they showed an expression of "it's only right."

Soon, the rather ugly-looking burly man ran in with a look of terror on his face.

"Zhao Tianming, why did this earth fire suddenly go out of control? My 'Breakthrough Pill' was about to be successfully refined, but it has been completely destroyed because of the out-of-control earth fire! How did you manage this earth fire land?" The old man glared at Zhao Tianming and roared angrily.

The others looked at the old man with surprise when they heard that he had refined a Breakthrough Pill.

This Breakthrough Pill is one of the few precious pills in the Foundation Establishment stage that can increase the chance of a breakthrough. Not only are the raw materials hard to find, but it is also difficult to refine. No wonder the old man was so angry.

Faced with the old man's unfounded accusations, the burly Zhao Tianming was on the verge of tears. It was true that he was in charge of this place, but with his Qi Refining stage cultivation, how could he possibly control the earth fire and prevent it from going out of control?

"Uncle-Master Ye, I don't know why the earth fire went out of control. The earth fire here has always been very docile, and such a thing has never happened before..." Zhao Tianming said with an ugly bitter smile.

"Then why did this subterranean fire suddenly go out of control?" Elder Ye was clearly furious and wouldn't listen to the other party's explanation.

"Senior Brother Ye, please calm down. Zhao Tianming is right. I have been to this Land of Earthly Fire many times, and nothing has ever gone out of control. There must be another reason for this!" one of the middle-aged men suddenly said.

Zhao Tianming looked at the middle-aged man with gratitude, wishing he could rush up and kneel down before him immediately.

Elder Ye was naturally aware of these things, but he still needed to vent his anger somewhere.

But now that the middle-aged man had spoken up for the other party, he couldn't afford to make things difficult for Zhao Tianming anymore, and could only let out a heavy snort.

Just then, an even deeper, more muffled sound came from within the fiery earth, and this time, because everyone was standing outside, they could clearly sense it.

Who is using the No. 3 fire house?
