Bai Yu said, "But we know nothing about the specific content and purpose of this ceremony, and rashly participating may lead to unpredictable consequences."

Xu Yuehuai's gaze remained unwavering. "If we cannot obtain the 'Secret Manual of Medicine' as soon as possible, all our efforts during this period may be in vain."

At Xu Yuehuai's insistence, they imitated every movement and incantation of the ancients. Although they knew very little about the deeper meaning of these rituals, they gradually became immersed in this sacred and solemn ceremony, guided by their vague memories of the ancient incantations and their intuition.

As the ritual progressed, the inner strength within them resonated subtly with the ancient power permeating the surroundings.

And the sealed "Secret Manual of Medicine" began to shine even brighter thanks to the three's tireless efforts. The sealing power gradually loosened, as if it was about to see the light of day again.

The three of them recited the final incantation in unison. With a deafening roar, the "Secret Manual of Medicine" in the crack trembled violently, and the seal binding it shattered completely. The book slowly rose and floated in front of the three of them, emitting a soft and warm light, like the rising sun, warm and full of hope.

"We got it!" Xu Yuehuai's voice was filled with barely suppressed excitement.

She clutched the book "Secret Manual of Medicine" tightly, as if she held the key to an unknown world.

Upon hearing this, Bai Yu and Bei Ye smiled sincerely, their eyes filled with admiration and affection for Xu Yuehuai.

“Xiaoyue, you are truly remarkable,” Bai Yu stepped forward and stood side by side with Xu Yuehuai, his gaze gently falling on the secret manual in her hands. “This book will surely lead the four countries into a new era of medicine.”

Bei Ye appeared more composed, "Yes, but more importantly, it can solve our immediate problem."

The three slowly turned the pages of the book, and the ancient characters seemed to come alive, transforming into streams of light that flowed directly into their minds.

Xu Yuehuai exclaimed with delight, "These texts are not just records, but also the crystallization of the wisdom of our ancestors in living in harmony with nature."

"I felt that power make my body much stronger." Bai Yu closed his eyes, took a deep breath, as if he could absorb the vitality permeating the surrounding air.

Bei Ye was completely immersed in the world constructed by the pages of the book. His expression was sometimes solemn and sometimes relieved, as if he was having a dialogue across time with the soul of an ancient physician. "This is not only an exploration of medicine, but also a profound insight into human nature and the laws of nature."

Suddenly, the scene in the secret chamber underwent a dramatic change. The ancient people, who had been still, seemed to be awakened by some force. Their eyes turned fierce, and the stone weapons in their hands gleamed with a cold light as they approached them step by step.

“It seems we’ve touched some taboo,” Xu Yuehuai quickly regained her composure and analyzed with a solemn expression, “Obtaining this secret manual doesn’t seem to be simple.”

"We have no choice but to speed up our retreat." Bei Ye tried to find a way out, but the walls of the secret room were impenetrable, and there seemed to be no gap for escape.

Bai Yu remained calm and said in a deep voice, "Don't rush. Since they were affected by the secret manual, perhaps we can make use of it." He closed his eyes, concentrated, and tried to communicate with the new power within his body.

"But we cannot destroy these relics left by our ancestors," Xu Yuehuai added.

Bai Yu smiled faintly, slowly opened his eyes, his gaze sharp as he surveyed the ancients around him who had awakened due to the secret text, and he had already made up his mind.

"We will not destroy the ruins, but we will not allow them to harm you either." Bai Yu gently raised the "Secret Manual of Medicine" in his hand, and suddenly his inner energy surrounded him, forming an invisible barrier.

"Try to feel this power; it might guide us out of this predicament," Bai Yu said, guiding the two to close their eyes and concentrate, immersing their minds in that ancient and mysterious power.

Xu Yuehuai and Bei Ye followed their instructions, and soon they felt that clarity and power. This power not only strengthened their bodies, but also made their minds exceptionally sharp.

As the three people's minds gradually merged with this power, the atmosphere in the secret chamber subtly changed. The eyes of those ancient people who were originally fierce and menacing began to soften, and the weapons in their hands no longer gleamed coldly, but slowly fell to their sides, as if soothed by some kind of power.

“Our understanding is correct,” Xu Yuehuai opened her eyes. “Our actions just now unintentionally touched the gentle power within the ‘Secret Canon of Medicine,’ allowing these ancient people to rest in peace.”

Bei Ye nodded in agreement: "Yes, true power is never about conquest and destruction, but about understanding and coexistence. If we can grasp the true meaning of this, we will surely benefit greatly."

Just as Xu Yuehuai and the other two were immersed in the strange power of the "Secret Manual of Medicine", everything around them became quiet.

Suddenly, a tremor broke the silence. The floor of the secret chamber shook as if it were alive. A huge stone slab covered with the dust of time slowly moved to one side to the astonishment of everyone, revealing a bright secret passage that seemed to lead to an unknown world.

At the same time, all those ancient people lost their lives and turned into clusters of colored light that merged into the stone wall, becoming murals.

"How come a new intersection suddenly appeared?" Bai Yu stared intently at the newly appeared road.

Xu Yuehuai's eyes shifted from shock to determination: "It was fate that led us to this path, but remember, our responsibilities are now even greater. These medical secrets must not fall into the wrong hands." Her tone was both resolute and worried.

Bei Ye dusted himself off, a wry smile playing on his lips. "Yes, I never expected we'd have such a serendipitous encounter. But those ancient people just now were truly terrifying. When they turned into light and merged into the stone wall, I felt as if I were witnessing a thousand years of vicissitudes."

“Indeed, those illusions, though false, serve as a warning that the path of medicine requires utmost caution at every step.” Xu Yuehuai waved his hand. “Let’s go, let’s carry this legacy and do something in the outside world.”

The three of them walked along the secret passage, stopping from time to time to discuss the ingenious aspects of the "Secret Manual of Medicine" and how to deal with the villagers who had been bewitched.

"Do you think these treasures can really help us treat more patients?" Bai Yu asked softly, clutching a jade pendant that had just broken off from the stone wall and was emitting a faint medicinal fragrance.

Along the way, they also occasionally obtained other treasures, most of which were related to medicine.

“Of course, but more importantly, how do we use this knowledge so that it doesn’t become a tool for power struggles?” Bei Ye’s answer was firm and resolute.
