That kind of feeling is just like the way he feels about gold-type real energy and power.
He immediately understood that after the sword embryo swallowed the magma and flames, it was gradually integrating the power of the flames.
The fiery feeling in his body was the power of flames, which was rapidly tempering his acupoints.
In just a few moments, the two acupoints in his fourth sword vein were tempered by the power of flames.
His strength has also quietly increased by 20%, and he is steadily moving towards the fifth level of Tongxuan Realm!
Although, Ji Tianxing still doesn't understand why the sword fetus has such miraculous effects and changes.
But he knew that now was an excellent opportunity to improve his strength.
He quickly sat down cross-legged in the golden shield, concentrating on practicing his kung fu, controlling the power of fire in his body, and continuing to temper his acupoints.
A quarter of an hour later, the tempering of the third acupoint was completed.
Two quarters of an hour later, the tempering of the fourth acupoint was completed.
Half an hour later, the fifth acupoint was completely tempered...
As time goes by, Ji Tianxing's strength is rapidly improving.
The magma and flames in the magma giant's belly were quickly swallowed up completely.
Up, down, left, right, in all directions, there was no trace of flame, not a drop of magma.
Its belly became empty, leaving only a shell made of black rocks.
The magma and flames were swallowed up, causing the magma giant's power to drain away quickly, and its body continued to crack open with cracks.
It roared and howled wildly, lying in the magma ocean and rolling in pain.
It didn't understand what was happening, but it struggled instinctively, opening its big mouth to continuously swallow the magma to make up for the lost power.
But all the magma it swallowed was swallowed up by Ji Tianxing's sword embryo.
Soon, three hours passed.
The magma giant is still flopping in the magma ocean, desperately swallowing countless magma.
But the speed at which it swallows magma is obviously much slower than the sword tire.
At this moment, its whole body has turned into a black reef. Without magma and flames, it can no longer be called a magma giant.
Its huge body burst into dense cracks, and the black reef was rapidly shattering and collapsing, falling into the magma ocean with a 'plop-plop'.
Five hours later, most of its body collapsed, leaving only half its body and half its legs.
One day later, its body had completely disintegrated and turned into a pile of broken black rocks, sinking into the magma ocean.
The magma giant completely disappeared and ceased to exist.
A golden giant sword appeared in the magma ocean, emitting invisible devouring power and continuing to devour the magma ocean and the sky-wide flames.
The bright golden light of the giant sword formed a circular shield, firmly protecting Ji Tianxing.
Ji Tianxing maintained his posture of sitting cross-legged, still closing his eyes tightly, still practicing his exercises to improve his strength.
Two days later, most of the vast ocean of magma was swallowed up, and the level of the magma sea dropped hundreds of meters.
Five days passed, and the entire magma ocean was swallowed up by the golden giant sword.
All directions turned into dark brown open spaces, with mountains of black rocks everywhere.
Even the scattered volcanoes became silent and turned into cold black stone mountains.
Five days ago, this area was a sea of fire, a world of magma and flames.
At this moment, there was no more firelight in this area, and it became a dark and cold world.
The color of the golden giant sword suspended in mid-air changed, becoming half golden and half red.
"Whoa!"
The golden shield disappeared, and the golden giant sword suddenly shrank, turning into a small golden-red sword. It flew back into Ji Tianxing's body and landed steadily in the black hole of Dantian.
Ji Tianxing felt something in his heart, ended his practice, and opened his eyes.
In just five days, his strength reached the fifth level of Tongxuan Realm from the fourth level of Tongxuan Realm!
Moreover, in the past few days, he has also used the power of fire to temper the nine sword veins again.
After being tempered for the second time, the sword veins have become tougher and stronger, giving him a deeper foundation and potential!
He used his spiritual sense to look inside and saw the sword embryo suspended in his dantian, which was faintly emitting surging and blazing flame power.
There is no doubt that he has possessed the second natal attribute and successfully controlled the power of fire!
He withdrew his spiritual sense to explore the sword embryo, and a pleased smile appeared on his face.
"Everyone has only one natal attribute and cultivates a certain power among the five elements."
"Only those who have reached the Tianyuan realm can control the power of the five elements."
"My birth attribute is gold. Now the sword embryo has swallowed up the magma flames, but it allows me to control the power of flames in the Tongxuan realm. This is simply a miracle!"
After muttering a few words to himself, he lowered his head and looked to his left hand.
I saw a red flame mark suddenly appearing in the palm of his left hand.
He could clearly detect that some miraculous changes had taken place in his left hand.
With a thought in his mind, he mobilized his true energy with all his strength and concentrated his power on his left hand.
Suddenly, his entire left arm turned as red as fire, as if it was formed by the condensation of magma.
He couldn't wait to test the power of his left hand, so he stretched out his left arm and slapped forward hard.
From the palm of his hand, he spurted out red flames that filled the sky, turned into a huge pillar of flame light, and hit a volcano ten miles away.
"Bang!"
Amidst the deafening sound, the thousand-foot-high volcano was shattered by the flame beam.
Half of the volcano collapsed and exploded, turning into rubble and splattering into the sky.
Ji Tianxing was stunned immediately, staring at the rubble in the sky, and let out an incredible cry.
"Oh my God! So powerful?!"
As soon as he finished speaking, the voice of Sword Soul Burying Heaven rang in his mind.
"Boy, this palm shot with all your strength used up 30% of the red flame real fire."
"If you try two more times and the Red Flame True Fire is used up, just practice and accumulate slowly!"
Zangtian's voice was low and cold, but there was a hint of joking in his tone.
Ji Tianxing suddenly understood and guessed that the change in the sword fetus must be related to Zang Tian.
He quickly dissipated the power in his left hand and returned his left arm to normal. He communicated with Zangtian through his mind and said, "Senior Zangtian, thank you for your help and reminder!"
"It's just a little effort." Zang Tian said in a calm tone: "The Red Flame True Fire is sealed in your left hand. Its power is too powerful and it is definitely not something you can control now."
"Only if you continue to improve your strength can you truly unleash the power of the Red Flame True Fire."
Ji Tianxing nodded and said to him: "I understand!"
Afterwards, Sword Soul Burial Sky said nothing more.
Ji Tianxing suppressed the excitement and surprise in his heart, looked at the surrounding rocks and open space, and began to look for the little black dragon.
He ran wildly in the vast open space for half an hour, and finally found the unconscious little black dragon on a volcano dozens of miles away.
