If Granny Si or the village chief were here, they would surely scold him for acting recklessly and risking his life.

After all, the divine sound that appears when breaking the wall is different from the divine sound emitted by the girls in the ruins. Using the demonic sound that counters the girls' divine sound to confront the divine sound during wall - breaking is not just a matter of using the wrong "medicine." The key is that if there are other strange changes in the divine and demonic sounds, it won't be as simple as losing his life; he might even be completely annihilated!

However, without anyone to guide him, Qin Mu was unaware of the dangers involved. As soon as he learned the demonic sound, he immediately started the experiment.

When his True Yuan reached the center of his eyebrows, the divine sound that seemed to come from beyond the Nine Heavens rang out again as expected. When the True Yuan encountered the divine sound, it automatically retreated. Qin Mu silently recited the demonic sound, and the divine sound and the demonic sound immediately became locked in a stalemate, colliding and attacking each other.

Qin Mu took the opportunity to urge his True Yuan to charge towards the Spirit Embryo Wall. However, the divine sound still broke through his demonic sound from time to time, forcing his True Yuan back.

He failed again and again but was not discouraged. He continuously stirred up his True Yuan to make attacks. After hundreds of failures, his True Yuan finally reached the Spirit Embryo Wall.

However, the Spirit Embryo Wall still remained intact and was not broken.

"I was interfered with by the divine sound and couldn't gather all my True Yuan for a full - force attack, so I couldn't break the wall."

Qin Mu briefly summarized his mistakes and immediately launched the next attack. After experiencing failure after failure, he finally made his True Yuan reach the Spirit Embryo Wall for the second time.

Again, he failed to break the wall.

Not long after, he made the third attempt, then the fourth, the fifth...

When learning medicine - making from the apothecary, he had developed great patience. Medicine - making requires a great deal of patience, wisdom, eyesight, and skills, with patience being the most crucial. Without patience, it is impossible to refine a good medicine.

After countless failures, finally, Qin Mu suddenly heard a soft "click" sound from the center of his eyebrows.

This soft sound was as beautiful as celestial music. Even though Qin Mu had strong self - control, he couldn't contain his excitement.

A crack appeared on the Spirit Embryo Wall, a crack in the shape of lightning.

The Spirit Embryo Wall was an invisible wall that could only be felt. But when this crack appeared, Qin Mu felt a ray of light shining from the center of his eyebrows, like a lightning - shaped symbol.

This feeling was very strange.

When you close your eyes, all you see is darkness, with no light at all. You can't see the center of your eyebrows, the Spirit Embryo Divine Treasure, or the Spirit Embryo Wall.

But when a crack is made in the Spirit Embryo Wall by the True Yuan, you can see a lightning - like light shining through the darkness. At this time, you can see the Spirit Embryo Wall.

Qin Mu not only saw the Spirit Embryo Wall but also caught a glimpse of the Spirit Embryo Divine Treasure through the lightning - shaped crack on the wall.

The Spirit Embryo Divine Treasure was filled with a dense, golden light, and abundant True Yuan was overflowing from the lightning - shaped crack, continuously merging with his own True Yuan.

The True Yuan in the divine treasure was more pure and powerful. However, like the True Yuan he had cultivated himself, it had no attributes.

Qin Mu firmly believed that the True Yuan he cultivated was the unique True Yuan of the Overlord Body, the Overlord True Yuan, so he didn't care about this at all.

The Spirit Embryo Divine Treasure contained not only True Yuan but also more mysterious things. But since he had only created a lightning - shaped crack and hadn't completely broken the wall, he couldn't see what else was inside.

The lightning - shaped crack was slowly healing. Qin Mu felt a little worried. Obviously, the Spirit Embryo Wall was not as simple as he had imagined. The Spirit Embryo Wall was tangible but intangible, like a viscous liquid, and could heal even if a hole was made in it.

Only by breaking the Spirit Embryo Wall completely in one go can the Spirit Embryo Divine Treasure be opened!

"My True Yuan cultivation is not strong enough yet, but creating a crack can make my True Yuan improve rapidly! It won't be long before my True Yuan can break the Spirit Embryo Wall!"

Qin Mu braced himself, when suddenly the crowing of a rooster reached his ears. His heart stirred, and he quickly opened his eyes.

Among the strange beasts that had taken refuge in the ruins, there were several bald - necked roosters. They were extremely tall and majestic, more than a person's height, with gorgeous feathers, but their necks were bare. The crowing just now came from these roosters.

"Dawn is approaching."

Qin Mu's heart stirred. A hazy light had appeared in the eastern sky, indicating that the sun would rise soon. He no longer had enough time to completely break through the Spirit Embryo Wall.

Fortunately, he had already understood how to break the wall. As long as he could escape from Senior Brother Qu and Senior Sister Qing, he would have plenty of time to make a breakthrough.

Although he hadn't completely broken the wall, just creating a crack had significantly improved his cultivation. He was confident enough to escape from the two of them!

"Dawn is approaching," Senior Brother Qu said meaningfully.

Senior Sister Qing said coldly, "Three junior brothers died while eliminating demons. If this little demon cub escapes, wouldn't it be a betrayal of their spirits in heaven?"

Qin Mu ignored them and stood up, stretching his muscles.

In the square, those young maidens still continued to confront the darkness, engaging in a fierce back-and-forth struggle that left them locked in a deadlock. The battle between darkness and light raged on brutally, a relentless clash of opposing forces.

Soon, another rooster crowed. The darkness became ，and its voice became extremely loud and deep. The divine sounds emitted by the girls also became passionate and resounding. The divine light and the darkness clashed violently, and the confrontation was astonishing.

Suddenly, the third rooster crowed. A ray of sunlight pierced the darkness in the east and landed on the highest nearby mountain peak.

Under the illumination of this ray of sunlight, the pitch - black darkness receded like a tide, quickly retreating into the distance. The darkness retreated as quickly as it had come, getting faster and faster, and finally disappearing over the horizon.

As the morning sunlight shone down on the canyon, before the sunlight reached the ruins in the canyon, the hanging pearl slowly descended, and the colorful glow filling the square poured into the pearl.

The glow disappeared, and the girls in the square turned back into skeletons, sitting cross - legged there motionless, as if the night's battle between the girls and the darkness had been just a magnificent dream.

Qin Mu had long heard the people in the village talk about the strange things in the Great Wilderness. The things that happened here were bizarre and unimaginable. However, hearing about them was one thing, and experiencing these strange events firsthand was even more shocking.

Whenever night fell and the darkness invaded, the face in the darkness, the mysterious demonic sound, the skeletons that turned into beautiful girls every night in this ruin, and the confrontation between light and darkness were all incomprehensible mysteries.

These secrets awaited people's discovery.

Qin Mu hid among the moving herd of beasts and quietly walked out. Apparently, the herd of beasts had an unwritten rule that no fighting was allowed in the ruins. However, outside the ruins, the herd of beasts might become extremely dangerous.

On the other side, Senior Brother Qu exchanged a glance with Senior Sister Qing, and the two also mingled with the herd, gradually closing in on Qin Mu.

The herd of beasts was still walking out in an orderly manner. Suddenly, a sword light quietly approached from behind Qin Mu. Qin Mu Dodge sideways，and the sword almost stabbed one of the strange beasts.

The strange beast let out an angry roar.

"Junior Sister, don't control the sword. If you injure a strange beast and the herd goes berserk, we'll all die here!"

Senior Brother Qu's voice came. Senior Sister Qing quickly withdrew her sword, jumped onto the back of one strange beast, then onto another, rapidly approaching Qin Mu. Qin Mu was envious. Gathering qi into a thread and controlling a sword to kill enemies dozens of zhang away was a remarkable skill, although not as astonishing as the Butcher's supernatural power.

Senior Sister Qing's steps were light. Her skirt spun like a pink lotus flower, and her toes under the lotus kicked towards Qin Mu like sharp knives!

Her leg techniques were sharp. Every kick was like a giant hammer with sharp spikes, making the air hum.

This kind of leg technique could easily shatter a large stone or pierce through an iron wall.

Qin Mu's eyes lit up as he met Senior Sister Qing's whirlwind - like leg techniques head - on!

The lame man had once told him that the Heaven - Stealing Leg Technique he taught him was never afraid of any other leg techniques!
