Rune Seal in Medicine Valley

Ten miles ahead, a massive canyon suddenly appeared in what had once been barren desert. Strangely, none of the surrounding yellow sand flowed into it, as though it were restrained by some force, leaving the canyon to form abruptly.

"What a rich medicinal scent..."

Xiao Yi Xian murmured to herself. She was extremely sensitive to the scent of herbs, and even before entering the canyon, she had already smelled the medicinal fragrance saturating the surroundings.

"This canyon was not naturally formed. It may have been carved out by that Dou Venerate before his death. I never expected the Jia Ma Empire to be hiding so many powerful experts."

The three of them stepped forward. Upon reaching this place, the black robe around Medusa vanished. She had worn it earlier mainly because she did not wish to cause a panic in Qingshan Town, or perhaps because Medusa simply did not want to spare those humans another glance.

When Xiao Yi Xian saw Medusa's nearly perfect face beneath the black robe, even she could not help turning to look at Medusa again.

Xiao Yi Xian was already exceptionally beautiful, but compared with Medusa, it was difficult to say...

After all, Medusa was not merely striking in appearance. The cold aura she exuded combined with her beauty, capable of toppling kingdoms and nations, to create an effect far greater than the sum of its parts.

Boom!

The Yin Yang Twin Flames instantly surged up, enveloping the three of them.

As the scorching Heavenly Flames appeared, Medusa could not help frowning slightly. The sensation of the flames burning so close to her made her extremely uncomfortable.

"Bear with it. The air here may contain poisonous gas. With the Heavenly Flames helping us, at least we will not be poisoned."

Lin Mu looked at Medusa and explained.

Medusa did not speak after hearing that. Her willow-leaf brows gradually relaxed. She seemed to feel that this human before her was not quite so irritating after all.

The light around them gradually dimmed. After entering the canyon, it was as if they had stepped into another space. Sunlight from outside could barely penetrate it, and only the glow of the Heavenly Flames allowed the three of them to continue deeper inside.

"You were right. The air here really is filled with poisonous gas."

A grave expression appeared on Xiao Yi Xian's pretty face. "What strange poisonous gas. Although it fills the surroundings, it does not seem to intend to enter our bodies..."

"Could it be because your constitution is special?" Lin Mu asked.

"Probably not. This poisonous gas appears to have leaked out, but it feels as though it possesses a certain awareness. Clearly, someone deliberately arranged this poisonous gas here."

Xiao Yi Xian shook her head, rejecting Lin Mu's guess.

Lin Mu and Medusa fell silent.

They did not understand what Xiao Yi Xian meant. Perhaps only because Xiao Yi Xian possessed the Calamity Poison Body could she so keenly sense the peculiar nature of the poisonous gas around them.

Xiao Yi Xian fell silent for a moment, then suddenly stepped outside the range Lin Mu had created with the energy of the Heavenly Flames.

Lin Mu was startled, but Xiao Yi Xian did not seem to suffer any problems, which made him breathe a slight sigh of relief. He seemed to have forgotten that the Calamity Poison Body was immune to all poisons. The poisonous gas here might even be an excellent medicine for Xiao Yi Xian's cultivation.

"The Calamity Poison Body truly is extraordinary."

Medusa spoke. Xiao Yi Xian was not even a Dou Practitioner, yet she could move freely here. Could it be that the poisonous gas cultivated by the Calamity Poison Body could even recognize its master on its own?

"We're here."

Medusa stopped walking.

Lin Mu and Xiao Yi Xian raised their heads at the same time. Within the dark canyon stood a structure resembling ruins, and before them was an enormous gate.

"Behind this gate should be the mysterious Medicine Valley, I presume. This was where you came before?"

Lin Mu asked Medusa.

Medusa nodded slightly and looked toward Xiao Yi Xian. Xiao Yi Xian had already walked up to the gate, and before her, layer after layer of intricate Rune Seals appeared.

"As expected, the Calamity Poison Body is recorded here."

Lin Mu also saw the words inscribed within the Rune Seals.

"The Calamity Poison Body is born from calamity and fades away amid calamity. I spent my entire life and finally found a method to control poison. Unfortunately, my own body suffered a mutation, and knowing that I did not have long to live, I found this barren place and left behind everything I had gained in my life, awaiting only a fated person of later generations to come here."

Xiao Yi Xian read the words recorded in the Rune Seals, covering her mouth with her delicate hand as she said in surprise, "The master of this place found a way to control the Calamity Poison Body?"

"However..."

Lin Mu and Medusa stepped forward.

"Even a Dou Venerate would perish because of it, so it cannot be an easy method. But since it exists, there is still hope. I will do everything I can to help you obtain it."

Lin Mu smiled.

"Thank you." Xiao Yi Xian nodded obediently.

"Is there a way to open this gate?"

Lin Mu frowned. The Yin Yang Twin Flames coiled around his palm, and he gently placed his hand against the gate. Unfortunately, there was no reaction at all.

If he forcibly broke it open, Lin Mu was worried that something unexpected might happen.

"These Rune Seals may contain the method to undo them."

"You should both step back. The poisonous gas here does not seem threatening to me, but you must be extremely careful."

Lin Mu nodded slightly, then turned to Medusa. "Listen to her. The poisonous gas of the Calamity Poison Body seems to be highly compatible with Xiao Yi Xian. Poisonous gas alone cannot threaten her."

"I do not need you to tell me what to do."

Medusa glanced at Lin Mu and turned to retreat some distance.

Lin Mu smiled helplessly and could only follow Medusa.

Xiao Yi Xian stared at the Rune Seals for a while, then cautiously placed her fair palm against them. The previously tranquil runes suddenly began flashing with streaks of light.

Xiao Yi Xian's expression changed, and panic surfaced on her face. For some reason, the Dou Qi within her body suddenly began to spiral out of control, then was absorbed by the runes before her.

"My hand... I can't pull it back..."

Xiao Yi Xian tried to withdraw her arm, but it seemed to be restrained by some force, leaving her unable to move.

Boom!

A loud crash rang out. Only then did Xiao Yi Xian weakly collapse to the ground. Her face was pale, but when she saw that the gate had loosened, she could not help smiling.

"It worked."

Lin Mu appeared beside Xiao Yi Xian and helped her up. Meanwhile, Medusa swept past them and entered through the gate.

"Are you all right?" Lin Mu asked.

"The seal absorbed my Dou Qi. It seems that only the Calamity Poison Body can open it." Xiao Yi Xian shook her head. Lin Mu could only sigh at that. It seemed this opportunity had truly been prepared for Xiao Yi Xian.
