Yang Che had already made a judgment regarding the strange medicinal scent within the iron cage.

However, he couldn't be entirely certain yet, so he prepared to secretly observe and continue to verify it.

But Sha Rou clearly didn't have much patience.

Moreover, Yang Che could tell that although Sha Rou was still cautious after entering this place, she also relied on her Core Formation Great Perfection cultivation, likely believing that her life was at least safe, and she didn't want to fall behind others when it came to Spirit Medicine.

Yang Che's gaze closely followed Sha Rou until two Late Stage Core Formation Cultivators appeared in front of Sha Rou, at which point he saw Sha Rou stop.

A very fat Cultivator quickly entangled Sha Rou.

Meanwhile, another tall and thin Cultivator took the opportunity to rush towards the entrance.

The only entrance to this 'iron cage' building was a fully open stone door.

Compared to the hundreds of feet high stone wall, this stone door, only a dozen feet high and several feet wide, appeared very small.

It wouldn't be an exaggeration to call it a stone window.

Just as the tall and thin Cultivator, with a wary expression, had just stepped into the stone door, suddenly, without any warning, a thick, dark green flood dragon snake abruptly extended its massive head and bit the Cultivator.

The tall and thin Cultivator was decisive; while activating a defensive Magic Treasure, a jade ruler appeared in his hand, instantly glowing with white light and becoming incredibly huge, firmly propping open the flood dragon snake's jaws, preventing it from fully closing.

Seeing the jade ruler work, a hint of joy flashed in the tall and thin Cultivator's eyes; just as he was about to escape from the flood dragon snake's mouth, he was suddenly swallowed whole by an even larger flying beast.

This scene not only startled Yang Che.

Even Sha Rou and the fat Cultivator, who were still fighting, were startled, and both immediately stopped and retreated rapidly.

However, the flood dragon snake swiftly swayed its long body, lunging towards Sha Rou and the fat Cultivator.

But the huge flying beast that had swallowed the tall and thin Cultivator did not follow out.

Soon, a shrill scream came from within the iron cage building.

At the same time, an incredibly strong smell of blood drifted out from within.

Clearly, the tall and thin Cultivator had most likely met with an unfortunate end.

Yang Che had been sitting in the bushes, continuously using the Stealth Technique.

At this moment, his expression was quite solemn.

He quickly pondered, and soon a glimmer of light flashed in his eyes.

Then, he immediately began to refine Medicinal Pills on the spot.

A type of Medicinal Pill called 'Nixia Pill' recorded in the Qing Yuan Dan Record.

Yang Che was neither afraid of exposure nor concerned about the battle between Sha Rou, the fat Cultivator, and the flood dragon snake; he calmly gathered materials from the Tongyou Medicine Garden and quickly refined 'Nixia Pill'.

This type of Medicinal Pill was only for enticement and was not a very high-grade Medicinal Pill, so Yang Che only spent half an hour refining seven of them.

Putting away the Pill Furnace, Yang Che's face showed a slight hint of regret.

The special medicinal aroma from refining the Medicinal Pills just now had tempted the giant flying beast to rush out of the stone door several times, but it ultimately retreated each time.

Yang Che directly revealed himself.

He saw that the fat Cultivator was already seriously injured, while Sha Rou was still engaged in a fierce battle with the Level 7 Yao Beast, the dark flood dragon.

Although the dark flood dragon's speed was inferior to Sha Rou's, its Physical Body was extremely tough, and Sha Rou's attacks repeatedly failed to be effective.

Yang Che merely glanced lightly before flying directly towards the stone door.

This action of his immediately startled Sha Rou and the fat Cultivator.

Especially Sha Rou, who immediately said anxiously, "Fellow Daoist Yang, don't be impulsive. You should come over and help me kill this flood dragon snake first."

When the fat Cultivator heard that the two actually knew each other, he no longer hesitated and immediately wanted to flee.

Sha Rou suddenly let out a cold snort, and disregarding the dark green flood dragon snake's attack, she directly controlled her long saber Magic Treasure, releasing a greatly intensified Saber Intent that flashed with yellow light, striking the fat Cultivator with lightning speed.

The fat Cultivator was horrified.

He couldn't understand why this beautiful and tall female Cultivator dared to ignore the flood dragon snake's attack.

With this huge doubt, the fat Cultivator, already heavily injured, was struck by the sudden saber light, and a large hole appeared in his chest.

At this moment, the dark flood dragon's tail also fiercely whipped Sha Rou.

However, the Ancient Treasure armor on Sha Rou's body glowed with an unusual light, blocking the attack for her.

Meanwhile, the fat Cultivator, with unwilling eyes wide open, softly fell to the ground, motionless and without any Qi.

Sha Rou reached out and retrieved the fat Cultivator's Storage Pouch, then swiftly flew towards Yang Che.

"Fellow Daoist Yang, that giant strange bird is not something we can defeat…"

Sha Rou's words were cut short before she could finish, unable to continue.

Because Yang Che had already stepped into the stone door.

The dark green flood dragon snake frantically twisted its body, attempting to intercept, but was suddenly blocked by a swarm of red insect clouds that appeared out of thin air.

This was Yang Che directly releasing 'Winged Fire Dragonfly', unhesitatingly controlling them to begin devouring the dark green flood dragon snake.

Piercing rustling sounds continuously echoed, and the huge flood dragon snake rapidly shriveled at a visible speed.

And as Yang Che stepped into the stone door, the giant strange bird from before indeed opened its huge mouth and lunged at Yang Che again.

Yang Che's expression was calm, without the slightest hint of panic.

With a gentle flick of his palm, a small yellow umbrella appeared and instantly grew against the wind, becoming larger than the strange bird's huge mouth, and with a rumble, the massive, yellow-glowing umbrella surface blocked the strange bird's attempts to swallow.

Doubt appeared in the strange bird's large eyes, but then its fierce gaze intensified, and a pair of sharp claws like hooks of copper directly gripped the umbrella surface.

The light on the umbrella surface was instantly shattered.

However, the yellow umbrella itself firmly withstood the strange bird's sharp claws.

Yang Che's eyes narrowed slightly, feeling the strong defense of the yellow umbrella, and only then did he slightly relax.

Then he quickly took out a 'Nixia Pill' and flicked it directly outside the stone door.

The colorful Nixia Pill released an incredibly powerful aroma in mid-air, causing excitement and madness to appear in the giant strange bird's eyes; as the aroma grew stronger, the strange bird finally couldn't hold back anymore and directly chased after the Nixia Pill.

Sha Rou was startled and was about to dodge, but then she suddenly heard Yang Che's voice transmission: "This strange bird's strength will greatly diminish once it leaves the stone door; you stop it and kill it."

Sha Rou was skeptical.

However, the scene before her quickly confirmed that Yang Che's words were true.

After the strange bird chased out of the stone door and swallowed the Medicinal Pill, the powerful Qi emanating from its body suddenly weakened too much.

Sha Rou naturally wouldn't miss this opportunity; the yellow moon long saber in her hand instantly lifted, and the yellow moon Saber Intent shot towards the giant bird's head like a meteor…

And Yang Che, having stepped into the stone door, immediately saw a rare Spirit Plant gathered into a spherical Sha E, the bloodline vine.

After burning a tall, shriveled corpse next to the bloodline vine to ashes, he dug it out whole and carefully placed it into the Void Illusion Magic Stone Space.

However, he did not place it in the Tongyou Medicine Garden, but specifically planted it in a large mountain near the Spiritual Vein.

And instructed Mie and Xiao Gu not to approach it at all.

The Qing Yuan Dan Record records: bloodline vine, an evil Ancient Spirit Plant that can only mature after being continuously watered with fresh blood.

Normally, it contracts into a spherical Sha E, but when attacked, it will extend countless thin vines like threads.

These thin vines possess an unpredictable corrosive power; it is rumored that even Soul Transformation Cultivators dare not easily touch a mature bloodline vine.

And the strange bird swallowing the tall and thin Cultivator earlier was to water the bloodline vine with his fresh blood.

The strange smell Yang Che perceived was also emitted by the bloodline vine.

Although he had never smelled this scent before, based on the detailed description in the Qing Yuan Dan Record, he still identified the bloodline vine.

Yang Che continued to go deeper, constantly picking Spirit Medicine along the way, and even found the 'soul fixing grass' he had been painstakingly searching for without success.

His excitement was beyond words.

His Divine Sense and Soul were already weak; although he had the Heavenly Evolution Art, Cultivation Technique still needed to be Cultivated slowly, while the Ancient Pill 'Soul Pill' could directly and quickly enhance his Soul strength.

The substitute main medicine for refining 'Soul Pill', soul fixing grass, even with Tianxie Ziyin's command, Zi Tian City Lord Sha E used all his power and could not find it in the entire Zi Tian Oasis.

But he never expected to find it in the outer reaches of this Ancient Remnant.

Yang Che calmed down, harvested all the 'soul fixing grass', whether mature or seedlings, and transplanted them all into the Tongyou Medicine Garden.

This way, he would have a continuous supply of soul fixing grass once he cultivated the Seed in the future.

At this moment, Sha Rou, with a somewhat displeased expression, had already caught up.
