The surface of the pitch-black xuan heavy ruler was engraved with some blurry, strange patterns.
These patterns extended from the handle, almost covering every part of the ruler's body, and combined with its ancient, dark color, it looked quite mysterious.
Looking at the giant black ruler before him, Xiao Yan, after several recollections, finally reached out and grasped it.
"Rise!"
Xiao Yan let out a low shout.
The terrifying strength he had gained from nearly five months of arduous Cultivation already far surpassed that of ordinary people; in fact, his current Physical Body strength alone could contend with a Dou Practitioner.
Even so, the moment he picked up the xuan heavy ruler, he felt a sense of strenuous effort.
Especially his Dou Qi, even after being refined and solidified, became even heavier the moment it was injected into the xuan heavy ruler.
Xiao Yan's face showed no fluctuation at this change, as he had long been accustomed to the feeling of holding the xuan heavy ruler.
The reason he asked Yao Lao to summon the xuan heavy ruler was to use its unique property to refine his Dou Qi one last time, and then achieve the goal of Cultivating the newly created Cultivation Technique.
For the next month, Xiao Yan continued his daily arduous Cultivation until his Dou Qi within his body was refined to an extreme, and his Physical Body strength also saw another small increase.
At that point, the fifth bottle of Foundation Establishment Divine Liquid was completely depleted from his consumption.
Winter had fully arrived, and a thin layer of ice began to form on the water surfaces in Utan City.
Under such cold, Xiao Yan quietly found a cave in the Xiao Family's back mountain and sat cross-legged inside, bare-chested.
After half a year of refinement, his Dou Qi had solidified to an extent that even Yao Lao found incredible, and his still-underaged Physical Body, beneath its clearly defined muscle lines, concealed an explosive power that could be called terrifying.
Along with the strengthening of his Physical Body and his continuous self-visualization over the past six months, Xiao Yan's Soul Power had long surpassed what it was when he first underwent Rebirth.
At this moment, his Soul Power was already stronger than most two-grade Alchemists.
Once he stepped into the Dou Practitioner realm, he would be comparable to a three-grade Alchemist or even stronger.
At that time, he would experience a heaven-shaking transformation.
"Half a year of arduous Cultivation was all for this moment."
With a light chuckle, Xiao Yan felt his incredibly solid Dou Qi, and his eyes turned to Yao Lao beside him.
"Teacher, let's begin!"
Hearing Xiao Yan's words, Yao Lao was slightly startled at first, then still looked at Xiao Yan with some concern and said, "Do you really want to use that method to Breakthrough to Dou Practitioner?"
"That is natural.
Only by using my method to Breakthrough to Dou Practitioner can my future path be smoother."
Xiao Yan smiled calmly, his eyes filled with confidence.
When it came to playing with fire, who in this Universe could be his opponent?
The name of Flame God had long spread throughout the Major Thousand Worlds in later generations.
After he became a Heavenly Sovereign, during the countless battles against the Extraterritorial Evil Clan, he evolved the Burning Art, and finally, after becoming a Dominator, he deduced an even more powerful Cultivation Technique than the Burning Art—the Flame God Art!
Seeing Xiao Yan's confidence, Yao Lao said no more.
He flicked his finger, and a yellowish Medicinal Pill the size of a Dragon's eye landed in Xiao Yan's hand.
This Medicinal Pill was called the Little Earth Spirit Pill, a weakened version of the Earth Spirit Pill that Xiao Yan had prepared for refining the Fallen Heart Flame, with all Materials replaced by those with lower Medicinal Pill effects.
Even so, refining this Little Earth Spirit Pill still depleted the three hundred thousand gold coins Xiao Yan had originally earned.
Fortunately, he later gave Ya Fei twenty bottles of Foundation Establishment Liquid, which helped his financial situation recover.
"Once I advance to Dou Practitioner, I can also refine Medicinal Pills myself."
A glint flashed in his eyes, and Xiao Yan reached out and swallowed the Little Earth Spirit Pill.
After the Little Earth Spirit Pill entered his abdomen, waves of pure, dense, and vast energy began to spread throughout Xiao Yan's body.
Over the past six months, the drop of Earth Core Spiritual Milk that remained each time Xiao Yan refined Foundation Establishment Liquid had been accumulated and then added to this Little Earth Spirit Pill.
Such dense and vast energy could only be endured by Xiao Yan's body, which had undergone refinement and tempering.
Otherwise, even if it were relatively mild, an ordinary youth at the Dou Qi stage would still have their Meridians burst in an instant.
After his nascent Soul Power sensed that the Little Earth Spirit Pill's energy had completely protected his body, Xiao Yan then turned his gaze to Yao Lao.
Seeing this, Yao Lao's expression was serious.
After a moment of hesitation, he finally condensed a wisp of Bone Spirit Cold Fire from his fingertips, flicked it, and sent that wisp of Bone Spirit Cold Fire before Xiao Yan.
Just this single wisp of Bone Spirit Cold Fire caused Yao Lao's face to turn slightly pale, and his figure became somewhat ethereal.
Clearly, this wisp of Bone Spirit Cold Fire was not an ordinary flame, but a wisp of sub-flame, or rather, a wisp of the Bone Spirit Cold Fire's Flame Origin.
Looking at the wisp of Bone Spirit Cold Fire floating before him, Xiao Yan grabbed the wisp of Bone Spirit Cold Fire sub-flame, which even Dou Spirit experts would be extremely wary of, without a second thought.
Then, under Yao Lao's slightly shrinking pupils, he slapped it into his mouth.
The moment the Bone Spirit Cold Fire was grasped by Xiao Yan, it began to frantically burn the energy light film from the Little Earth Spirit Pill that covered Xiao Yan's body with terrifying high temperatures.
For an ordinary person, even with the protection of the Little Earth Spirit Pill, they would probably be quickly burned to ashes.
Fortunately, Xiao Yan was incredibly familiar with strange flames.
The moment the Bone Spirit Cold Fire entered his mouth, Xiao Yan immediately began to mobilize his Soul Power to make this wisp of flame quickly refine along the path of his Flame God Art.
As if sensing the danger, that wisp of flame immediately began to struggle frantically.
Its terrifying power caused even Xiao Yan's Meridians, protected by the Little Earth Spirit Pill, to experience extreme pain.
"Behave yourself!"
Xiao Yan snorted coldly.
His Soul Power, which had been severely consumed by the Bone Spirit Cold Fire, suddenly became incredibly solid.
Although there was no flame, a more terrifying high temperature seemed to faintly appear in the Void Realm.
Invisibly, a wisp of incredibly brilliant flame phantom quietly appeared above his head.
The moment that wisp of phantom appeared, that wisp of Origin flame seed trembled, then immediately became incredibly docile, like a mouse encountering a cat.
Yao Lao, witnessing this scene, couldn't help but change his expression drastically, because the moment this wisp of flame phantom appeared, even the complete Bone Spirit Cold Fire within his body trembled slightly, as if worshiping this wisp of flame phantom.
After using that simulated Emperor Flame aura to awe the wisp of Origin flame seed, Xiao Yan quickly mobilized his Soul Power and Dou Qi together to push the temporarily docile Bone Spirit Cold Fire to rapidly move through his Meridians.
He spent a sleepless night.
When the sky of the next day faintly showed a hint of dawn, Xiao Yan's face was pale, but his eyes showed no fatigue; instead, they were incredibly bright.
Within his lower abdomen, a wisp of the Bone Spirit Cold Fire's Origin flame seed quietly floated, now completely tamed.
However, after being refined by Xiao Yan, although this wisp of flame seed still possessed the attributes of Bone Spirit Cold Fire, it subtly gained a more terrifying essence.
This essence would, as Xiao Yan's strength continuously increased and the number of strange flames he devoured grew, eventually evolve back into Emperor Flame.
"Emperor Flame Seed, formed!"
