Xu Yuehuai patted the two on the shoulders: "As long as we have good intentions and uphold the benevolence of doctors, no matter how many people want to stop us, we will definitely be able to walk a bright path that belongs to us alone."

Both of them laughed and agreed, showing complete agreement with her words.

Within this deep and unfathomable secret passage, time seemed to stretch out, each second carrying the weight of life and death. Three days might be just a fleeting moment to the outside world, but for Xu Yuehuai, Bai Yu, and Bei Ye, it was an extremely long time.

"Clang!" The sudden, crisp sound, like the whisper of death, instantly shattered the silence in the secret passage.

The three of them leaped up almost reflexively, their bodies tracing graceful arcs in the air before landing steadily, avoiding the deadly trap hidden beneath the stone slab.

After landing, Bei Ye looked up at Xu Yuehuai and Bai Yu, his eyes filled with both fear and defiance: "This secret passage is truly terrifying, every step feels like walking on a knife's edge."

Xu Yuehuai said, "That's why every step we take is all the more meaningful. Every time we escape danger, it's a test of our will and a hurdle to improve our abilities."

“That’s right. We must not only get out of here alive, but also carry this experience with us to become stronger,” Bai Yu said, clenching his fist.

Suddenly, a deep rumbling sound came from the depths of the secret passage, accompanied by a strong tremor. The ground beneath their feet instantly came to life, and huge rocks covered with sharp spikes slowly rose from all directions, completely blocking their escape route.

Faced with this sudden turn of events, the three of them did not panic. Instead, they stood even closer together, their eyes filled with trust and encouragement for each other.

"We need to find a way to move these stones." Xu Yuehuai calmly analyzed the situation, his eyes scanning the boulders for a possible breakthrough.

"I'll try to shake them off with my internal force." After saying that, Bei Ye took a deep breath, his internal force surged throughout his body, and he pushed out his palms. A powerful force burst out from his palms, but the boulder only trembled slightly and did not move at all.

“We can’t force it. These stones seem to be connected by some kind of mechanism,” Bai Yu carefully observed his surroundings, then suddenly his eyes lit up. He pointed to a seemingly ordinary stone wall and said, “Look, there seem to be traces of a mechanism here.”

The three immediately gathered around and examined it carefully, discovering that this was indeed the secret to activating the mechanism.

Bei Ye pressed a hidden button on the stone wall. With a complex mechanical sound, the spiked boulders slowly descended and disappeared back into the ground, and the passage was clear again.

"We can walk again!" Bei Ye exclaimed excitedly, his face beaming with the joy of surviving a disaster.

"When you think you've reached the end of the road, a new path opens up!" Xu Yuehuai strode forward once again.

Xu Yuehuai and his group proceeded cautiously, step by step, in the dim light.

As they walked further and further away, a strange sense of oppression followed them like a shadow, as if the entire cave was silently protesting their departure.

"Xiaoyue, watch your step!" Bei Ye's voice suddenly rang out, tinged with urgency.

Xu Yuehuai looked down and saw a seemingly calm puddle of water that shimmered with an unusual luster under the dim light.

Just as everyone was trying to take a detour, the water suddenly boiled, and colorful tentacles, like living things, snaked out of the water, their target Xu Yuehuai in the group.

"What dares to hurt my sister? Die!" Upon seeing this, Bei Ye's eyes widened in anger. In a flash, he drew his sword, its light flashing like lightning, and slashed straight at the seven-colored tentacles.

However, these tentacles were exceptionally agile, easily avoiding the attacks, and instead coiled around the attackers even more frantically.

"Xiaoyue, don't stand there, it's dangerous!" Bai Yu shouted anxiously, moving swiftly to block Xu Yuehuai's path. A small silver device had appeared in his hand; with a gentle press, it instantly unfolded into a fine net, precisely covering the tentacles. A powerful suction force then drew the tentacles, along with the water beneath them, into the net, where they vanished without a trace.

"What is this?" Xu Yuehuai asked in surprise, looking at what Bai Yu was holding.

Bai Yu smiled mysteriously and explained, "This is my secret weapon—'Purifying Net,' which can absorb and purify all evil things."

The danger here had just been resolved when a series of subtle yet dense sounds suddenly came from above their heads. Immediately afterward, countless tiny black shadows emerged from the cracks in the rocks. These were small beetles they had never seen before. They frantically vibrated their wings and spat out green venom, filling the air with a pungent odor.

"Get out of the way! This venom is corrosive!" Bei Ye shouted a warning, while quickly taking a protective suit out of his backpack and handing it to Xu Yuehuai.

Bai Yu activated his "Clear Sky Net" again. This time, he did not attack directly, but cleverly used the airflow generated by the net to disperse the venom, avoiding direct contact.

“This place is truly fraught with hidden dangers!” Xu Yuehuai said calmly. “But we can’t let this mess affect our mood; we need to get out of here quickly.”

But they had only walked a short distance when suddenly a sharp and shocking sound came from all directions.

The sound seemed to penetrate one's soul, instilling fear and almost shattering one's internal organs.

They all covered their ears, their faces showing pain.

"Where is this sound coming from?" Xu Yuehuai tried to remain calm and search for the source of the sound.

With his keen intuition, Bei Ye quickly located a narrow crevice on the side of the cave, where a faint light was flickering, accompanied by that terrifying sound.

"That's it!" Without hesitation, he rushed forward, picked up a stone of similar size from the ground, and precisely inserted it into the crevice.

With a "crack," the chilling sound abruptly stopped, and the cave returned to deathly silence.

"That was close, I almost got overwhelmed by that sound." Bei Ye wiped the cold sweat from his forehead and exclaimed.

"The slower we go, the more dangerous it might be. Let's speed up!" Xu Yuehuai quickly used her internal energy and activated her lightness skill to accelerate her pace.

Over the next three days, Xu Yuehuai and her group encountered even more terrifying crises. But with their wisdom, abilities, and teamwork, they overcame them one by one and found a way out.

As the first rays of sunlight pierced through the exit of the secret passage, they emerged just then.

Although they were somewhat tired, they were in particularly high spirits.

Now, they are no longer the naive teenagers who first entered the secret passage, but warriors who have become more resilient after experiencing life-and-death trials.

“We’re finally out.” Bei Ye looked up at the long-lost blue sky, his tone a mix of relief and emotion. “But the outside world seems to be more complicated than inside the ruins.”
