"Okay!" Looking at the jade bottle floating in front of him, Zhao Yi's eyes also had a touch of solemnity. Although the white-bearded old man said it easily, as long as he ran this geocentric flame in the meridians for a week, he would be able to refine it successfully, but Zhao Yi knew that when he really did it, it was far from being as easy and freehand as he said.

Zhao Yi took the jade bottle containing the Cold Ice Pill, put it aside, then sat down cross-legged and began to breathe.

Refining the Earth's Core Flame is an extremely difficult matter, if he can't adjust his state to the peak, Zhao Yi will never start easily.

Looking at Zhao Yi, who was not in a hurry to refine the fire of the earth's heart but directly closed his eyes to breathe, a flash of approval flashed in the eyes of the white-bearded old man, but then it was replaced by a hint of coldness. His real purpose is far from being as simple as what he said to Zhao Yi, and after he assists Zhao Yi in refining the Earth's Core Flame, it is time for him to implement his true plan!

Time passed slowly, and an hour passed in a blink of an eye, Zhao Yi was still immersed in pranayama cultivation, and the white-bearded old man's expression did not change at all. He had been waiting here for thousands of years, and when he saw that his long-cherished wish was about to come true, how could he care about waiting a few more hours?

Finally, when the third hour passed, Zhao Yi's tightly closed eyes finally opened, and his whole body exuded a sharp aura. Under the pranayama of these three hours, the spirit spirit has finally reached the peak level!

"It's time to start!" Zhao Yi smiled and picked up the jade bottle beside him, pouring out a crystal white elixir from it.

The surface of the elixir was covered with a thin layer of ice crystals, which looked extremely bright. When the pill rolled down on Zhao Yi's palm, a faint layer of frost quickly condensed on Zhao Yi's hand.

"Goo!"

Zhao Yi raised his palm, raised his neck, and swallowed the cold ice pill in his hand.

As soon as the Cold Ice Danfu entered the abdomen, the powerful power of cold ice instantly exploded in Zhao Yi's body, and Zhao Yi's body surface quickly condensed a layer of white frost, looking like a snowman!

"Quick, run the internal qi to guide the power of the Cold Ice Pill. The white-bearded old man's voice sounded, and there was a shock in the air, Zhao Yi hurriedly sealed his hands, and his internal qi quickly worked in his body, guiding the energy of the Cold Ice Pill to spread all over his limbs.

In a short time, all of Zhao Yi's meridians, including the surface of the dantian, were covered with a layer of crystal white energy, exuding an extreme chill.

"Absorb the fire of the earth's core and start refining. The old man's voice rang out again.

Zhao Yi stretched out a palm and probed towards the slowly rising flames of the earth's core. As he approached the fire in the center of the earth, Zhao Yi's palm suddenly burst out with a strong suction, sucking it into the meridians in his body.

"Boom!"

The extremely hot energy exploded in Zhao Yi's body, and the layer of crystal white ice energy on the surface of Zhao Yi's meridians quickly became cold.

Zhao Yi didn't dare to slack off, and immediately activated his internal qi, guiding the earth's core flame to move slowly in the meridians.

In the meridians that exuded coldness, a golden-red flame flowed slowly, and where the flames passed, it quickly dissolved the cold energy attached to the four walls of the meridians.

Under such alternating cold and heat, he inadvertently carried out an ice and fire quenching for Zhao Yi again!

Carefully pulling the golden-red flame in the meridians, Zhao Yi began to feel bursts of burning pain in his body. After all, although the energy of the Cold Ice Pill is strong, it is also a little dwarfed when facing the geocentric flame of this legendary Fire Row First Treasure Ten Thousand Fire Emperor.

With the loss of time, the power of the Cold Ice Pill began to decrease, and the pain in Zhao Yi's body became more and more intense, but the good news was that the fire in the center of the earth at this time had been running in Zhao Yi's meridians for more than half a week.

Perhaps it was a premonition that he was about to be refined, and the fire in the center of the earth suddenly became manic. The powerful power of the flame violently erupted in Zhao Yi's meridians, and suddenly, the cold ice pill energy that enveloped Zhao Yi's meridians was quickly dissolved, and a wisp of golden-red flame directly scorched on Zhao Yi's meridians.

"Poof!"

A pain that went straight to the depths of his soul erupted from Zhao Yi's body, directly causing Zhao Yi to spurt out a mouthful of blood.

Clenched his teeth, Zhao Yi's eyes flashed with a determined light, and continued to guide the geocentric flame to run in the meridians, and as the distance from running for a whole week got closer and closer, the resistance of the geocentric flamefire became more and more intense, Zhao Yi's mouth and nose began to ooze blood, and even his body began to tremble uncontrollably, and under that trembling, there were actually drops of blood, which began to slowly ooze out of the pores around Zhao Yi's body, and the white robe also began to slowly turn bloody.

"Such tenacious willpower, even compared to me back then, it is not worse at all, but I was the peak cultivation of the Xuanzun Realm back then......!

The fire in the center of the earth was raging wildly in Zhao Yi's meridians, and the blazing temperature came out of the meridians, through the bones, acting on Zhao Yi's flesh and skin, and the skin that was slowly oozing blood began to spread out blood-colored cracks, and blood flowed out of it.

Although the condition of his body was gradually getting worse, Zhao Yi could clearly feel that the fire in his body seemed to have a faint connection with himself.

"There is only the last section left to run for a whole week, hold on!" Zhao Yi's eyes flashed with a crazy color, and he suddenly exerted force, and all the meridians in the dantian quickly gushed out, pushing the earth's core flame directly through the last meridian.

Rumble!

The furious blazing heat broke out in an instant, and Zhao Yi's already cracked flesh and blood suddenly exploded at this moment. Blood splattered. Zhao Yi's eyes gradually dimmed.

At this moment, Zhao Yi was almost facing a life-and-death crisis, and the fire in the center of the earth was still the last trace of distance before the entire Zhou Tian was completed.

At this moment, as if sensing Zhao Yi's crisis, the small sword in the depths of Zhao Yi's mind began to spin wildly, releasing a large stream of innate sword energy, integrating into Zhao Yi's meridians, and began to repair Zhao Yi's meridians that were burned to the ground.

Under the infiltration of innate sword qi energy, Zhao Yi's meridians were rapidly recovering, and Zhao Yi's eyes also rose with dazzling light again!

"Give me refinement!" Zhao Yi roared angrily, his voice hoarse. The last trace of the journey in Zhao Yi's meridians to refine the fire in the center of the earth passed by!

In an instant, the furious geocentric flame became docile, quickly flowing through Zhao Yi's meridians, and finally flowed into Zhao Yi's dantian.

As soon as the earth's core flame entered the dantian, the small sword in the dantian suddenly emitted a burst of light, absorbing all the earth's core flames, and then, the small sword quickly changed into a golden red color, and the sixth strange pattern on the sword body began to improve rapidly, but in a moment, the sixth pattern was completely perfect, and then the seventh pattern appeared, which was also rapidly becoming perfect, followed by the eighth and ninth lines. Nine golden-red innate sword qi were constantly rotating around the golden-red small sword.

And Zhao Yi's breath is also constantly rising, the sixfold peak of the innate realm, the sevenfold peak of the congenital realm, the sevenfold peak of the congenital realm, and the eightfold peak of the congenital realm...... It wasn't until the ninefold peak of the Innate Realm that it stabilized.

When the ninth strange pattern was approaching perfection, next to the golden-red small sword, another small sword appeared out of thin air, and there was not the slightest line on the small sword. Around this small sword, there are also nine innate sword qi around!

At this moment, Zhao Yi's cultivation broke through to the peak of the innate realm, and the cultivation of the Sword Heart Technique also entered the second realm!

The golden-red sword emitted a stream of powerful energy, which merged into Zhao Yi's body, and Zhao Yi's fleshy body began to recover quickly under the fusion of these energies. These energies are manifested by the power of the fire in the heart of the earth to reshape the physical body.

Seeing this scene, a satisfied look flashed in the eyes of the white-bearded old man: "It seems that the refining has been successful, and next, it will be my turn to play!"

After a while, Zhao Yi's fleshy body had recovered as intact as before, and his skin was as smooth as jade, which made people feel like they could be blown away.

"It seems that the refining has been successful, how does it feel?" Seeing Zhao Yi recover, the white-bearded old man asked with a smile.

"It feels pretty good, but the feeling before was extremely painful!" Zhao Yi shook his head and said.

"In that case, then hand over your body, and in the future, I will protect him for you!" Hearing this, the white-bearded old man's expression suddenly became hideous, and his eyes showed a cold glow.

"What do you want to do?" Seeing this, Zhao Yi was shocked, and a look of panic appeared in his eyes.

"Of course I'm going to take you away! Surrender your body obediently!" The white-bearded old man laughed strangely, his body turned into a cloud of light and shadow, rushed towards Zhao Yi's head, and finally completely submerged in it!
