Starting as a stray dog, I embarked on a journey of cultivation.

Upon hearing this, Gou An suddenly realized what was going on.

Shen Yu deliberately borrowed a large amount right away, which would definitely make the other party refuse and put them in a difficult position. Then he borrowed a smaller amount, which would naturally increase the probability of the other party agreeing.

As expected, the Valley Master of Divine Fire's expression softened considerably after Shen Yu lowered his demands, and he said, "It's not that I'm unwilling to lend you the fire, but are you really going to use it to fight the Demon King?"

Before Shen Yu could answer, the Valley Master of Divine Fire Valley continued, "Do you know that the Demon King Huang Ku is a powerful demon in the Nascent Soul stage? Although he belongs to the wood element, he cannot be easily dealt with by innate spiritual fire alone!"

"Senior!" Shen Yu cupped his hands and said, "I was just joking with you. How could I possibly go and deal with that demon king? I was just using this fire to refine pills."

"Oh?" The Valley Master of Divine Fire was somewhat skeptical after hearing this.

Shen Yu smiled and said, "As you know, my mother is limited by her talent and can only stay at the Golden Core stage for her entire life, unable to transcend to the Divine Realm. Therefore, her lifespan is coming to an end, and we have been searching for a way to prolong her life."

"I recently obtained an ancient prescription on the black market. It requires innate spiritual fire to refine a longevity pill, which is why I have come to bother you."

Faced with Shen Yu's explanation, the Valley Master of Divine Fire nodded and said, "Why didn't you just say it was for your mother?"

At this point, the Valley Master of Divine Fire flipped his hand and took out a ball of burning flame.

Gou An cast his gaze. The flame looked ordinary, but its color was much darker inside, as if it contained a mass of flowing magma.

"This is the Earth Vein Flowing Fire that I have refined!" The Valley Master of Divine Fire slowly said, "This fire ranks fourth among the innate spiritual fires of heaven and earth. It is rooted in the underground lava fire vein. The fire is long-lasting. Although its explosive power is not top-notch, it is the most stable and powerful. It is not difficult to control. Whether it is for refining pills or forging magic weapons, it is unparalleled. Even if it is used for direct combat, it is much more useful than ordinary magic weapons."

The Valley Master of Divine Fire held the dark, swirling flame in his palm and casually gave a brief introduction to its characteristics: the firelight was gentle and calming.

As soon as he finished speaking, he flicked his fingertips, and the ball of earth vein fire floated into the air, landing steadily in Shen Yu's palm, transforming into a gentle flame that was extremely obedient.

"Keep it safe and use it with care."

Shen Yu clenched his fist, put away the fire seed, and immediately bowed, saying, "Thank you, senior. I will return to return it as soon as I am done."

After saying that, he turned around, intending to leave with Gou An.

But just as he took a step, the voice of the Valley Master of Divine Fire came from behind him, abruptly stopping him.

"Wait a minute."

Shen Yu paused and looked back.

The Valley Master of Divine Fire shook his head slightly and sighed softly, "Fine, fine, for your mother's sake, I'll give you the Solar Golden Fire!"

"The fire of the earth veins is ultimately a bit too weak. If the fire is not controlled properly when refining the pills, it will damage the appearance of the pills and delay your mother's important matter of prolonging her life. That would be a loss."

Before he finished speaking, he flipped his hand again and produced another item.

Gou An looked up and saw a perfectly round, white fireball floating in his palm. Its golden light was both restrained and domineering, and it was surrounded by fine golden flames.

From a distance, it truly looked like a miniature sun held in the palm of one's hand, and the temperature of the entire cave suddenly rose several degrees.

"This is the Sun Gold Fire, ranked first among innate spiritual fires." The Valley Master of Divine Fire solemnly instructed, "This fire is the most yang and strongest innate spiritual fire in the world. It is the master of all fires, capable of burning all things, dissolving all evil, and possessing boundless power."

"Remember to be extremely careful when using it, lest you injure yourself."

"Most importantly, this Solar Golden Fire was slowly refined by me by absorbing the power of the sun bit by bit. Every bit used is a bit less, so we must not waste it."

After saying that, he raised his hand and gently pushed the small golden sun out.

Shen Yu quickly reached out and caught it, afraid that the fireball would fall to the ground if he wasn't careful. After he had a firm grip on the fire element, he clenched his palm again and put the fire element away.

He then nodded emphatically and bowed deeply, saying, "This junior will remember your instructions, senior!"

"Hmm!" The Valley Master of Divine Fire nodded and said, "In that case, return the Earth Vein Fire to me. This Solar Golden Fire is enough."

But Shen Yu's eyes flickered slightly, and he spoke up, his tone sincere and natural: "Senior, since both spirit flames have already been given to me, why don't I take them both with me and return them together later!"

"Hey!" The Valley Master of Divine Fire immediately pointed at Shen Yu and said, "How dare you get so arrogant, brat? It's just alchemy; one is enough for you. You want to take two with you?"

"Senior!" Shen Yu smiled, "One or two are all fire to you, aren't they? They'll all be sent back to you eventually anyway."

After saying this, Shen Yu didn't wait for the Valley Master of Divine Fire to refuse, and turned to leave. Gou An could only hurry to follow.

Upon leaving the cave, Shen Yu, as if afraid that the Valley Master of Divine Fire might change his mind, steered his flying boat into the sky and disappeared in the blink of an eye.

Once the flying boat had flown far away, the Valley Master of Divine Fire Valley flew out of the waterfall and landed on the cliff. He watched the direction where Shen Yu's flying boat disappeared for a long time.

Finally, he sighed deeply and said, "With these two balls of spiritual fire, we can at least have some means of self-defense against that barren wasteland."

Meanwhile, aboard the airship.

Shen Yu piloted the flying boat and officially began flying towards the Monster Mountain Range.

Gou An walked up to Shen Yu and said excitedly, "Young Master Shen, could you perhaps show me the Solar Golden Fire and the Earth Vein Flowing Fire?"

"What?" Shen Yu turned around and asked.

"Do you remember when I detoxified you last time?" Gou An laughed. "I also used innate spiritual fire, but it was the eighth-ranked Ten Thousand Poison Fire. I happen to have some knowledge of these spiritual fires, so I'm quite interested in them."

Shen Yu thought for a moment and finally nodded in agreement: "Okay, but you have to be careful."

"Don't worry, young master, I'm an alchemist, and my fire control skills are more than enough," Gou An chuckled.

Shen Yu then flipped his hand and took out the Earth Vein Flowing Fire, handing it to Gou An.

Gou An held the ball of fire, which resembled flowing magma, with great curiosity.

This fire has been refined, making it essentially a magical artifact.

Simply infuse it with spiritual energy, and you can draw upon the power of the fire within.

In Gou An's hands, the Earth Vein Fire sometimes transformed into the shape of a dragon, sometimes into the shape of a tiger, sometimes into a sword, and sometimes into a knife.

In Gou An's hands, the fire was like an extremely obedient toy, which he could control at will.

After playing with it for a while, Gou An was pleasantly surprised to find that his fully formed Flame Saint Body could actually replicate this flame.

So he quickly circulated his spiritual energy and began to manipulate the earth vein fire while slowly replicating the fire seed within his body.

After completing the replica, Gou An returned the fire seed to Shen Yu.

Although the Earth Vein Fire Seed replicated within the body is very small at this time, it can slowly grow as long as it is nurtured with spiritual energy.

"Young Master, let me take a look at the Sunfire too!" Gou An chuckled, becoming increasingly excited.

Shen Yu put away the Earth Vein Fire, and then took out the Solar Golden Fire and handed it to Gou An.

After obtaining the Solar Flame, Gou An immediately tried to replicate it, but after trying for a long time, he found that the flame could not be copied.

After studying it for a long time, Gou An finally discovered the reason.

This ball of golden solar fire is not a seed of fire, but a preserved element of fire. No wonder the Valley Master of Divine Fire said that every bit used is a bit less.

The difference between a fire seed and a fire element is that a fire seed has roots and can grow. As long as the fire seed is not destroyed, it can continue to generate energy.

Fire element, on the other hand, is merely a preserved flame, like a rootless duckweed; once used, it's gone and cannot grow on its own.

So Gou An simply played with the Sun Gold Fire for a moment before returning the fire element to Shen Yu.

"With these two spirit flames, how much of your divine power would you have if you were to fight the Demon King?" Gou An asked curiously.

Shen Yu thought for a moment and slowly replied, "Now that I have reached the Divine Realm, although I am two minor realms lower than the Demon King Huang Ku, I am not incapable of fighting him. With the attribute restraint of the Sun's Golden Fire and the Earth Vein Flowing Fire, I am probably 40/60 against him."

"So confident?" Gou An was somewhat surprised and couldn't help but retort, "Could it be that he killed six times in four quarters of an hour?"

Shen Yu was amused by Gou An's words and said, "Even if it's not 40/60, we can still barely manage a 30/70 split!"

He paused for a moment, then added, "However, I'm not here to fight him to the death, so I'll avoid fighting if possible."

"Alright!" Gou An nodded, then emphasized, "Why don't you give me the benefits you promised me first? Like you said before, if I find Yun Yao's whereabouts, you'll give me more benefits?"

Reminded, Shen Yu nodded: "Don't worry, once we get to the City of Ten Thousand Demons and I meet that female demon Yun Yao, I'll definitely make sure you're well taken care of."

"I think it's more reliable to give it to me now," Gou An emphasized again.

Shen Yu glanced at Gou An and laughed, "What? Afraid I won't give it to you?"

"No?" Gou An shook his head: "I'm so afraid that you'll get killed by the Demon King if you go. How am I supposed to ask you for it then?"

After hearing this, Shen Yu sighed and ultimately did not refute it. Instead, he took something out of his pocket.

Gou An took it and discovered that it was actually a jade slip.

"What's this?" Gou An asked, looking puzzled after taking it.

"There are 300,000 low-grade spirit stones in here that I stored at the Spirit Storage Manor," Shen Yu said. "I didn't bring many spirit stones with me this time because I was in a hurry. You can get them later when you have the chance."

Upon hearing this, Gou An probed a wisp of spiritual energy into the jade slip and found that it contained the certificate for the Spirit Storage Manor. He quickly put it away.

"Also, what are your plans once we arrive at the City of Ten Thousand Demons?" Gou An asked curiously.

Shen Yu replied, "I'll cooperate with you to see the Demon King first. I need to see the specific situation before deciding on further plans."

"I only have one request!" Gou An suddenly said.

"What?" Shen Yu asked.

"If a fight really breaks out, could you choose a time when I'm not around?" Gou An laughed. "Otherwise, it wouldn't be right for me not to help the Demon King."
