Chapter 37 Gu He's Grand Project, the Comatose Yun Yun
After a while,

Lu Yu and Hai Bodong slowly walked out of Gu Te's strange residence.

Hai Bodong stroked his silver-white beard and said unhurriedly, "Boy, in my opinion, you don't need to worry. It's actually a good thing that the Ice Spirit Cold Spring has fallen into Gu He's hands."

As he spoke, he stopped, a glint of light flashing in his cloudy old eyes, and continued, "I have heard much about the Five Serpent Poison Seal when I traveled through the Jia Ma Empire. The most troublesome aspects of this seal are nothing more than two points."

"Firstly..."

Hai Bodong raised a finger and said solemnly, "It is the sealing power that has fused the life-long fighting spirit of five Dou Wang powerhouses. It is said that when this seal was at its peak, it could even suppress a Dou Huang powerhouse to the Dou Ling realm."

"Secondly..."

He raised a second finger, his brow furrowing slightly, and continued, "It's a mixture of potent poisons hidden within the seal. If it's not treated in time, the poisoned person probably won't survive more than a month..."

At this point, Hai Bodong suddenly patted Lu Yu on the shoulder, a smile appearing on his lips: "But for you, these two points are not a problem at all."

“Firstly,” he pointed to Lu Yu’s dantian, “the strange fire in your body is much stronger than those fifth or sixth-order beast fires, so dealing with mere snake venom is naturally no problem.”

"Secondly..."

A look of reminiscence flashed in Hai Bodong's eyes as he slowly spoke, "You even broke the serpent seal curse that Queen Medusa herself placed on me. No matter how strong this Five Serpent Poison Seal is, can it possibly surpass that person's methods?"

“So,” Hai Bodong clapped his hands and laughed, “in my opinion, Guhe’s bounty is tailor-made for you. If you take action, others will probably not even get a taste of the soup.”

Upon hearing this, Lu Yu's eyes flashed with a sharp light, but he suddenly frowned and asked, "Elder Hai, can Gu He... still be trusted?"

He subconsciously touched his dantian, "As fellow alchemists, if I use a strange fire to detoxify that Yunlan Sect Master, will he...?"

"Hahaha!" Hai Bodong suddenly burst into laughter, his laughter tinged with disdain. "You're being far too cautious, kid."

He suppressed his smile and said seriously, "Although Guhe is pedantic, his integrity as an alchemist is impeccable. Besides..."

A sly glint flashed in Hai Bodong's eyes: "With me by his side, if he dares to harbor any wicked thoughts..."

Before he finished speaking, a chilling aura suddenly burst forth from his body, and a thin layer of ice instantly froze on the ground.

Upon hearing this, Lu Yu nodded thoughtfully.

According to his memories from his previous life, he had indeed never heard of Guhe doing anything that was an act of ingratitude.

Moreover, Elder Hai has now recovered to the level of a seven-star Dou Wang. As a veteran Dou Huang powerhouse, his strength is probably enough to rival that of a nine-star Dou Wang powerhouse. Even if a Dou Huang doesn't appear, ordinary people can't do anything to them.

The matter of curing Yunyun's poison is something we can consider.

"However, this matter needs to be considered carefully. Mr. Hai, we might as well gather some information first and then make a decision before taking action."

Lu Yu pondered for a moment before saying this.

Hai Bodong nodded and said, "That's only right."

……

Soon after,

Inside a hotel room.

Lu Yu was sitting quietly in his room when the door was suddenly pushed open.

"Young man Lu, take a look at this."

Hai Bodong strode in and slammed a gold-embossed bounty poster on the table. "Even I'm tempted by the bounty posted by Gu He. This Pill King of the Yunlan Sect is certainly generous."

He stroked his beard, a glint of shrewdness flashing in his eyes: "It seems that the situation of that Sect Master Yun is more troublesome than we imagined."

Lu Yu unfolded the bounty notice, which read: "I, Gu, sincerely invite the strongest people in the world to help me break the Five Serpent Poison Seal. Anyone who lends me the help of a fifth-order beast fire will be rewarded with a fifth-grade pill."

If anyone can break the seal, I will reward them with a sixth-grade elixir; if any expert can break the seal and remove the poison at the same time, I, Gu, am willing to repay them with three attempts at alchemy.

If you righteous warriors do not need elixirs, you may exchange them for equivalent cultivation techniques, combat skills, or rare and precious materials. I, Gu, will do my utmost to satisfy you.

During the detoxification process, I, Gu, guarantee your safety in my capacity as a sixth-grade alchemist, and the entire Yunlan Sect will do everything in its power to protect you.

At the end of the signature, Guhe's sixth-grade alchemist badge shone brightly, highlighting the weight of this promise.

"Truly generous..."

Lu Yu looked at the reward notice, nodded, and a thoughtful look flashed in his eyes. He said, "In that case, Elder Hai, let's disguise ourselves and head to Qingnangzhai."

"Hehe, kid, this is the fifth thing."

Upon hearing this, a smug look flashed in Hai Bodong's eyes, and he said with a smile.

Lu Yu was taken aback at first, then shook his head and chuckled: "So you were waiting for me here, sir. No wonder you were being so attentive today..."

……

Soon after,

As dusk settled, in front of an elegant pharmacy in the eastern district of Blackrock City.

The three gilded characters "Qing Nang Zhai" above the pharmacy's door gleamed with a warm luster in the twilight, and the pharmacy was brightly lit.

Inside the apothecary, dozens of people dressed in alchemist robes were conversing in hushed tones, their silver badges gleaming under the lamplight. Passersby invariably stopped to watch, casting awe-inspiring glances at these noble alchemists.

Two men in black robes weaved through the crowd, their silver masks gleaming coldly in the lamplight. A servant in blue hurriedly approached, bowing respectfully: "Are you two distinguished guests here seeking medicine, or are you here because of Master Guhe's bounty?"

"A reward," the black-robed man on the left said in a low voice, "Where is the patient?"

The servant turned his gaze to the burly man in black robes on his right, and hesitated before saying, "This one..."

“My guards,” the man in black robes on the left said calmly.

Just as the servant was about to ask another question, a gentle voice suddenly came from the inner hall: "Since you are an honored guest who has come to remove the Five Serpent Poison Seal, please come in."

Gently lifting the beaded curtain, the candlelight flickered in the inner room, illuminating the surroundings.

A middle-aged man with a slightly haggard face stood quietly in front of the medicine shelf, his brows revealing a hint of fatigue. However, the sixth-grade alchemist medal he wore on his chest clearly indicated his identity—he was none other than the Pill King Gu He.

Upon seeing the two enter, Gu He's gaze lingered on the silver mask for a moment before finally settling on the chest of the black-robed man on the left—where it was completely empty.

"You dare to come here to break the Five Serpent Poison Seal without even wearing your alchemist badge? Are you trying to make a fool of me?"

Guhe's voice turned slightly cold, and he asked with a hint of doubt.

The man in black robes merely chuckled, and with a wave of his hand, a wisp of bluish-red flame danced merrily in his palm, radiating a terrifyingly high temperature that sent chills down one's spine.

"Strange fire?"

Gu He's pupils suddenly contracted, and he involuntarily took a half step back. He stared intently at the flickering cyan-red flame, his Adam's apple bobbing, his eyes flashing with a complex expression of shock, envy, and disbelief.

As a sixth-grade alchemist, he knew better than anyone the value of the strange fire—it was a treasure he had been searching for for half his life but could not obtain!
However, he quickly took a deep breath, suppressed the pounding in his heart, and solemnly clasped his hands in greeting, saying, "I was rude just now. Sect Master Yun is in the inner room. Please follow me."

As they spoke, the three of them passed through layers of curtains and entered the inner room. The room was filled with the fragrance of herbs, a rich aroma that lingered in the air.

On the bed, Yun Yun slept peacefully. Her black hair cascaded down like a waterfall, her eyebrows were delicate and arched, and her pale skin was like the finest mutton-fat jade. However, five serpentine black wisps writhed menacingly between her brows, intertwining like living creatures, adding a touch of eeriness and fragility to her stunning beauty.

Lu Yu's pupils, hidden beneath his mask, suddenly contracted—the toxicity of the Five Serpent Poison Seal was three times more potent than he had anticipated!
