To comprehend all laws and attain immortality

The exquisite wood core is the key to Gu Fan's creation of the spirit in the gray rat.

The Wind-breathing Rat belongs to the Wood element, which is compatible with the Exquisite Wood Heart. In addition, the powerful vitality of the Exquisite Wood Heart can ensure that it will not be overwhelmed by excessive energy.

Chang Yuan's essence and blood are of the water element, relying on the order of mutual generation of the five elements, with water generating wood.

Although you won't die, the process is far from pleasant.

The moment the golden Six Ding Divine Fire surged, the gray rat shrieked.

The blood vessels throughout the body are gradually invaded and devoured, followed by intense pain and a sudden swelling of flesh and blood.

Gu Fan patted the Returning Origin Furnace and comforted it, "Bear with it! Pain is normal; it means you're getting stronger."

The Guiyuan Furnace ran for an entire night.

The squirrel's cries had long since ceased, not because it was no longer in pain, but because it had fallen into a coma.

Gu Fan used his divine sense to examine the situation inside the furnace. Seeing that the spiritual spring had returned to its transparent color, he nodded and took out the Fire Scale Horn, throwing it in.

Intense flames erupted from the Guiyuan Furnace, and the gray rats squeaked again.

After fusing with the Exquisite Wood Heart, the gray rat's wood attribute is greatly enhanced. Adding the Fire Scale Horn is to use wood to generate fire, thus allowing it to absorb all three spiritual creatures.

The next day, the fire in the Guiyuan Furnace gradually faded.

The spiritual energy from all directions seemed to be summoned, slowly converging into the furnace and forming a vortex outside the Blue Stone Palace. Its power was no less than that of Gu Fan when he was building his foundation!

At the same time, a beam of light flew towards Phoenix Perch Island, and the person in the beam stopped in his tracks upon seeing the vortex.

"Is this... someone building a foundation here?"

The person who arrived was Chen Yunfan, a disciple responsible for guarding the second floor of the duty hall, who was quite familiar with Gu Fan.

The cyclone lasted for a full half hour, and the Guiyuan Furnace began to shake slightly.

Seeing this, Gu Fan became serious and cast a series of hand seals to firmly suppress the Returning Origin Furnace.

A moment later, black, blue, and red spiritual light emerged from the Guiyuan Furnace.

"It's time!" Gu Fan's face lit up with hope, and he pointed his finger like a sword at the Returning Origin Furnace, shouting, "Open!"

In an instant, the three-colored spiritual light surged, piercing through the stone walls and protective formations of the Green Stone Palace and soaring straight into the heavens.

A flash of inspiration vanished in an instant, and the Returning Origin Furnace remained silent.

Gu Fan raised an eyebrow, tapped the furnace wall with his finger, and then a rustling sound came from inside the furnace.

A strange, mythical creature, resembling both a rat and a snake, crawled out.

The spirit beast is about two feet tall. Its main appearance is similar to that of the Wind Breath Rat, but the fur on its body has disappeared and is instead covered with a layer of blue scales. It has two short, crimson horns on its head, a strip of fiery red mane on its back, and its eyes have become large and lively. Its tail is also much thicker.

"Awooo!" The spirit beast roared twice at Gu Fan.

"Hey, even its bark has changed!" Gu Fan smiled and stroked the fur on its forehead, feeling its soft, warm texture.

The gray rat had signed a spirit contract with Gu Fan before the spirit was forged. Now, feeling Gu Fan's caress, it narrowed its eyes and shook its round head slightly.

After teasing him for a while, Gu Fan said, "Let me see your talent!"

The gray rat's original bloodline talent was only to sense auras, but after fusing with various spiritual materials, especially Chang Yuan's essence blood, Gu Fan could not predict what other bloodline talents it possessed.

The gray rat was stewed in the Returning Origin Furnace for three days, and the abundant spiritual energy directly propelled it to the second tier.

But Gu Fan knew this was not the limit; the remaining energy was still lurking in the gray rat's meridians and flesh, and needed to be further developed and mobilized.

Black smoke silently spread, and Chang Yuan emerged.

Chang Yuan was also curious about the gray rat that had been infused with his blood essence. Two red lights flickered in the black smoke as he silently watched it.

Upon hearing this, the gray mouse tilted its head and pondered for a while, then opened its mouth wide and pointed.

"Is it... hunger?"

Gu Fan was both amused and exasperated, so he took out a pill and handed it to the gray rat.

Unexpectedly, the gray rat did not take it. Instead, it turned its head and looked around. When it saw the remaining Six Ding Divine Fire under the Guiyuan Furnace, its eyes lit up and it opened its mouth to inhale.

The Six Ding Divine Fire was immediately drawn in and flowed into the gray rat's mouth like water.

After swallowing all the flames, the gray rat let out a burp, twitched its small nose twice, and spat out two flames.

Gu Fan frowned slightly as he watched this scene, and hesitated before asking, "You can devour flames?"

The gray mouse nodded, then shook its head.

"This is my secret technique of devouring the heavens!"

Chang Yuan's voice trembled slightly, and two beams of red light surged from the black mist as he exclaimed in shock, "You've really gotten a treasure, kid! It actually awakened my Devouring Heaven Secret Technique!"

Gu Fan was overjoyed upon hearing this, and the corners of his mouth couldn't help but turn up in a smile.

The Devouring Heaven Secret Technique is Chang Yuan's core ability. This innate technique played a crucial role in Chang Yuan's achievement of the Void Refinement Realm!

"Don't get too excited!"

Just then, Chang Yuan reminded him, "Its Devouring Heaven Secret Technique is far inferior to mine! When I was at the second level, I wouldn't have been reduced to this state by just one flame."

Gu Fan paid no attention to these words.

Although the gray rat's Devouring Heaven Secret Technique is not strong enough, it will gradually improve as long as it absorbs more of Changyuan's essence blood in the future.

"Besides this, is there anything else?" Gu Fan asked again.

Upon hearing this, the gray rat suddenly puffed out its cheeks, leaned back slightly, and its two horns on its head shone brightly. It then opened its mouth and spat out a crimson fireball.

The fireball struck the stone wall of the quiet room, instantly burning a six-foot-wide hole in the wall, through which the furnishings of another quiet room could be seen.

Gu Fan was startled, thinking that the gray rat had spat out the Six Ding Divine Fire it had swallowed, but he quickly realized that this was not the case.

The Six Ding Divine Fire is golden in color and is refined from the Samadhi True Fire Text, possessing a stable nature.

However, the flames that the gray rat had just spewed were extremely violent, comparable to the Six Armor Divine Fire.

This is not a flame that devours, but a talent that the gray rat itself possesses!

The gray mouse stared at the burnt hole in the wall, thinking it had caused trouble, and covered its ears in fear with its two short little hands.

Gu Fan laughed heartily and comforted him, "It's alright, it's alright!"

After calming it down for a while, Gu Fan suddenly realized that he had never named the gray rat before. He stroked his chin and pondered for a moment, then looked at the gray rat's large head and short, chubby body, his eyes lit up, and he said, "I'll call you Gourd!"

The gourd, a homophone for good fortune and prosperity, was a beautiful symbol in Gu Fan's previous life.

Upon hearing the name, the gray rat jumped up and down with joy, while Chang Yuan was somewhat dissatisfied, believing that the spirit beast that inherited his bloodline should have a more majestic and domineering name.

Unfortunately, neither Gu Fan nor Hulu paid him any attention.

Just then, a sound transmission talisman landed on Phoenix Perch Island.

Chen Yunfan waited outside Phoenix Perch Island for a long time, thinking that someone on the island was building a foundation and dared not disturb them rashly. He only sent out a communication talisman after the spiritual light dissipated.

After Gu Fan summoned the communication talisman, he walked out of the Qing Shi Palace, where Chen Yunfan was already waiting outside the formation.

"What brings you here, Senior Brother Chen? Is it a summons from the sect?" Gu Fan asked.

Chen Yunfan nodded, but did not immediately mention the recruitment. After bowing respectfully, he asked, "Which junior brother was establishing his foundation here just now? We should congratulate him."

Gu Fan was slightly taken aback, then laughed and waved his hand, saying, "It's not that someone has reached the Foundation Establishment stage; it's just that one of my spirit beasts happened to advance."

"In that case, congratulations, junior brother." Chen Yunfan said with a smile, but inwardly he was shocked.

Although he didn't know Gu Fan's combat abilities, he did know that Gu Fan had escaped unscathed from the Luofu Secret Realm and gained 40,000 merit points.

The gourd's advancement was far more impressive than that of ordinary spirit beasts, which made Gu Fan's image in his mind even more profound.

After exchanging pleasantries, Gu Fan led Chen Yunfan into the great formation.

The two sat down under the stone table, and Gu Fan asked directly, "Senior Brother, you've come in person, so the sect's summons must be extremely important?"

Upon hearing this, Chen Yunfan nodded solemnly and took out a token from his sleeve.

Gu Fan raised an eyebrow.

Surprisingly, it was just a gold token.
