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

The black-robed domain lord's gaze was fixed on the flickering green flame in Gou An's palm, and he asked in a deep voice, "How do you plan to refine the poison?"

"This is one of the innate spiritual flames, the Myriad Poison Flame."

Gou An slightly raised his palm, and the eerie green flames flickered gently: "As long as the young master is placed in a pill furnace large enough for a person to sit cross-legged, I can use the Myriad Poison Fire to refine the pills and completely remove the strange poisons that are entrenched in his meridians."

Upon hearing this, the black-robed domain lord frowned even more deeply, his unease deepening.

"Ten Thousand Poison Fire? I've heard that this fire itself is extremely poisonous, so how could it possibly neutralize the poison within the body?"

"Lord of the Domain, you may not know this," Gou An slowly withdrew the flames from his palm and calmly explained, "The Myriad Poison Fire uses myriad poisons as fuel and is naturally able to restrain all poisons in the world."

"Use poison to fight poison, and use the properties of fire to draw out the toxins from the young master's meridians, so that they can be directly burned in the furnace."

"However, this method has a drawback: during the refining process, the fire poison clashes with the strange poison in the body, making the process extremely painful."

The black-robed domain lord neither immediately agreed nor refused. After a moment of silence, he sighed softly, "The antidote you came up with looks like some kind of heretical and crooked method."

Gou An swallowed hard and replied, "But the Domain Lord has already tried all the orthodox alchemy methods. If ordinary methods could work, there would be no need to come to me with these unorthodox methods."

Upon hearing this, the black-robed domain lord chuckled softly, turned to look at Yu'er beside him, and softened his tone: "Yu'er, would you be willing to give it a try? To put yourself into the furnace and be refined by the raging fire, just hearing about it makes one suffer excruciating pain."

The handsome young man gently clenched his fists, which were resting on his knees, and looked up at the black-robed domain lord, his voice calm: "Father, it's alright."

"Since I was poisoned, I have suffered from the torment of the poison day after day. Pain has become a daily occurrence for me."

Seeing his son nod in agreement, the black-robed domain lord finally made up his mind and allowed Gou An to use this second secret method.

He raised his voice towards the door and ordered his men on duty: "Quickly find a large alchemy furnace, big enough to seat a person, the bigger the better!"

After giving his instructions, he turned to look at Gou An, his eyes flashing with coldness again, and solemnly warned, "Remember this: if anything goes wrong during the detoxification process, you will surely die."

Gou An nodded emphatically after hearing this: "Domain Lord, rest assured, I value my life very much and would never joke with my own life."

"That's good!" The black-robed domain lord nodded and pointed to the chair beside him: "You can sit down and rest for a while. We'll begin as soon as the alchemy furnace arrives."

"Yes!" Gou An bowed slightly, found a chair, and sat down to rest.

In less than half an hour, a giant alchemy furnace was set up in the square downstairs.

The group went downstairs and looked up. The furnace was enormous, with a wide belly that could easily accommodate several people at the same time.

Gou An stepped forward and carefully examined the furnace walls and opening, confirming that the furnace was intact and without cracks. Only then did he lift the heavy furnace lid and turn to the black-robed domain lord, saying, "Domain lord, please have the young master enter the furnace and sit cross-legged. Leave the rest to me."

The black-robed domain lord gently patted the handsome young man's shoulder, comforting him, "Yu'er, if you can't hold on halfway, just call me!"

"Father, don't worry, I can do it!" The handsome young man took off his shirt and walked towards the alchemy furnace with his bare chest.

When he reached the entrance of the alchemy furnace, he hesitated for a moment before going inside and sitting cross-legged in the middle of the furnace.

Gou An closed the furnace door, placed his hands on the furnace wall, and took a deep breath.

I've tried using this method to remove toxins from spiritual plants myself, but this is the first time I've used it on someone else to detoxify them.

However, at this critical juncture, regardless of whether the method works or not, we have no choice but to try it.

Having mentally prepared himself, Gou An began to exert slight force with both palms. In the next instant, a dark green flame suddenly ignited in the empty alchemy furnace and began to rotate around the furnace, surrounding the handsome young man in the middle.

The black-robed domain lord stood outside the alchemy furnace, peering inside through the ventilation gaps, his heart pounding with tension.

He couldn't help but remind Gou An again, "Take your time, don't rush!"

"Don't worry, Lord!" Gou An didn't dare to be careless at all, and slowly controlled the rotating Ten Thousand Poison Fire to move closer to the handsome young man in the middle of the furnace.

In order to prevent the poisonous fire from harming the opponent, Gou An could only control the poisonous fire by turning it into thin, needle-like threads of fire.

Then, controlling these fiery threads like acupuncture needles, they were inserted into the young man's body.

In an instant, the handsome young man, who had been expressionless, suddenly frowned in pain and gritted his teeth.

"Yu'er!" Upon seeing this, the black-robed domain lord unconsciously clenched his fists, immediately filled with worry.

He glanced at Gou An, who was still trying to control the flames, and then at the handsome young man struggling in the furnace, his heart filled with increasing turmoil.

Gou An merely offered a reminder: "Domain Lord, calm down. This is only the beginning. Don't disturb me, or all our efforts will be in vain!"

After saying this, Gou An closed his eyes and focused all his attention on controlling the Myriad Poison Fire.

At this moment, several wisps of Wan Gu Poison Fire had already entered the young man's meridians, and began to slowly refine the toxins attached to them along the meridians.

However, these toxins have been attached to the meridians for a long time, as if they have taken root, making them extremely difficult to remove.

Forced to maintain a precarious peace, they could only slightly increase the intensity of their attack, but kept it within the limits that their meridians could withstand.

After doing so, the toxins indeed began to be slowly refined and absorbed by the Myriad Poison Fire.

Unfortunately, the poisonous fire that entered the young man's body was weak. Each time a portion of the poison was refined, it was necessary to control it to return along the same path and then find a nearby location to re-enter the poisonous fire.

Repeating this process repeatedly will naturally make the pain unbearable.

The handsome young man, sitting cross-legged in the oven, cried out in pain, his steamed bun sweating, as if he were being tortured.

Seeing this, the black-robed domain lord instinctively wanted to stop refining the poison and prepare to rip open Gou An's robes.

"Father, stop!" The handsome young man, who had been sitting cross-legged in the stove, suddenly shouted, then opened his eyes, which were already bloodshot: "I can feel that the poison attached to my body is slowly disappearing. I can hold on."

Upon hearing the handsome young man's words, the black-robed domain lord withdrew his hand and took a few steps back, no longer disturbing him.

Inside the furnace, each of the poisonous flames that had burrowed into the young man's body emerged with a few strands of black sediment on its surface, which were quickly refined and dissipated within the furnace.

In this way, a full hour passed.

The young man's screams from the furnace had weakened considerably, but Gou An had not stopped.

"How is it? How much longer?" The black-robed domain lord couldn't help but ask again.

"Domain Lord, don't be impatient!" Gou An sighed and said, "We've only just refined the weak points of the poison; we'll soon be refining the stubborn poison near the heart."

"This step is the most difficult and painful!"
