In an instant, twenty days passed.
On this day, over Tai Yin Cave, the yin wind suddenly blew strongly. The giant enchantment on top of the cave emitted rolling yin qi which condensed into clusters of gray clouds.
The next moment, with a sound resounding across the sky, a lifelike black mist dragon and a black misty tiger rose soared into the air of the Tai Yin Cave. They began to circle and intertwined, the dragon and tiger roar sounded endlessly.
Above the Yin Cave where Liu Ming was, strange gray spirit patterns suddenly appeared in the air. After a few flashes, they trembled violently. A large amount of yin qi gathered and gradually formed a giant vortex on the top of the cave.
A visible distortion appeared around the vortex, then a spiritual pressure that was not weaker than the Crystallization Period soared into the sky along with the dragon and tiger and went into the vortex.
There was a loud rumbling noise.
The vortex gathered by yin qi condensed slightly, then it dispersed in an instant. Waves of yin qi spread to the surroundings.
After ten minutes, everything gradually returned to calm.
Although each yin cave had a partition enchantment, some disciples who cultivated in the nearby yin cave still felt the violent fluctuations of yin qi in the cave.
At the same time, in the Tai Yin Cave’s stone chamber, the old man in yellow robe, sitting cross-legged in front of the blue array, opened his eyes slightly.
“It’s just a breakthrough to the Condensation Period later stage, and the momentum is so big. Although this Tiger Dragon Hell Prison is a bit crude and some people don’t seem interested in its cultivation method, it was still a superior technique. How many years had passed since such a phenomenon appeared? Which courtyard’s inner disciple made such a breakthrough.” The old man said to himself, then he closed his eyes calmly.
At this moment, the yin cave, where Liu Ming was at, was filled with black mist. The mist tumbled as the black dragon and tiger rolled in it.
Liu Ming opened his eyes and made a gesture. The surrounding black mists transformed by the dragon and tiger turned into a thick black gas, soared into the air, and went into his head.
“Congratulations… Master… for break… breaking… to the Condensation Period… later stage.” At this moment, a girl’s stuttering voice sounded in his ears.
After Liu Ming smiled at the corner where Bone Scorpion was, he stood up, stretched his hands, and a crackling noise immediately came from all his bones.
He clenched his fist harder, and his arm swelled up in an instant. Black spirit patterns loomed on his skin. After suddenly turning around, he punched the boulder in an instant.
The boulder shattered inch by inch, and the flying stones splashed everywhere.
Liu Ming took a deep breath, and a satisfied expression flashed across his face. He only used 10% percent of his strength on this strike.
He gently pointed at the stone wall several ten meters away with one hand. A black mist instantly condensed from his fingertips, and flew towards the stone wall.
The next moment, there was a wave of fluctuations in the space in front of the stone wall, and a hole appeared on the surface of the stone wall. The gray rock powder suddenly scattered all over the place.
After Liu Ming continued to launch a few strikes toward the stone wall, he stopped with satisfaction.
At this time, even if the pulse connecting spiritual talisman had lost its effectiveness, the meridians in his body were slightly strengthened compared to the previous ones. As he channeled his strength, the spiritual power in his meridians surged. The power of mystic arts and techniques were also more powerful under this situation.
And the spiritual power in his Spiritual Sea had almost condensed into a gel-like change. His spiritual power should be close to the early stage of the Crystallization Period. His spiritual power was more than doubled to deal with the next absorption of the mysterious bubble.
Since his spiritual power had increased sharply, under the effect of Hell Bone Secret, his physical strength had increased by 30% as compared to before.
In this way, his body was comparable to the general Crystallization Period cultivators. He was even sure that he wasn’t weaker than the Crystallization Period Physique Cultivator.
Now, only twenty days had passed since he entered the yin cave, he still had more than ten days to consolidate his realm with peace of mind.
He threw the two upper grade soul-recovering bags and the other leather bag on the ground on his waist, and then he made a gesture and gently pointed at them. After the three spiritual bags flashed slightly, they continued to absorb the nearby yin qi.
Since he had advanced to the later stage, he could naturally replenish the yin qi of the soul-recovering bags at ease.
After briefly communicating with Bone Scorpion, he sat cross-legged again, ready to consolidate his realm.
After closing his eyes, a light flashed in the sea of consciousness. A pitch-black classic entangled with black gas appeared. It was the Tiger Dragon Hell Prison!
These days he had been carefully trying to figure out the third level in the classic. According to the descriptions, after he broke through to the Condensation Period later stage, his Tiger Dragon Hell Prison would also be increased to the third level.
The third level techniques were quite mysterious and difficult to understand. He had just figured out a clue. It seemed that it would take a long time for him to understand thoroughly.
Thinking of this, Liu Ming’s mind moved, and the classics in the sea of consciousness began to turn page after page.
Time flies; a few more days had passed.
On this day, Liu Ming was using the multitasking ability to adjust the spiritual power in his body to consolidate his realm while comprehending the third level of the Tiger Dragon Hell Prison with his mental power.
Suddenly, a buzzing sound came from a leather bag thrown on the ground!
Liu Ming opened his eyes in amazement, stopped his action, and glanced into his leather bag.
This bag seemed to be containing Demon Flying Skull!
The Demon Flying Skull had been sleeping in the leather bag since it swallowed a lot of the crystals and bone blood in the troll head, and there had been no sign of awakening.
After Bone Scorpion awakened, its strength had greatly improved, and it even got new magical powers. This naturally made Liu Ming look forward to the advancement of Demon Flying Skull.
After thinking for a while, he launched a symbol at the leather bag.
A cloud of pitch black gas came out of the leather bag. After a strange laughter, the black gas condensed and the real body of Demon Flying Skull appeared.
After sleeping in the leather bag for so long, the green hair on the head of Demon Flying Skull looked more vivid and eye-catching. The small white heads on both sides of the skull were also slightly enlarged. A layer of gray and black appeared on its surface, and the black gas on its body surface was thicker than before.
But what disappointed Liu Ming was that the aura of Demon Flying Skull didn’t increase much. It still seemed to be at the realm of the Condensation Period intermediate stage.
As soon as his mind moved, he immediately used his Divine Thought to communicate with it.
Unexpectedly, Demon Flying Skull seemed to ignore Liu Ming’s Divine Thought. After taking a deep breath, a greedy look appeared in the fiery red demon pupils. It opened its mouth and started to greedily swallow the surrounding yin qi.
The other two smaller, white skulls also made strange cries of “excitement” and made the same behavior with their mouths open.
After a few seconds, a whirlpool soon appeared around it, and yin qi in the cave surged into its mouth from all directions.
Seeing this, Liu Ming’s eyes flickered slightly, but he did not stop it. He was just watching quietly by the side.
With a scream, Bone Scorpion was lying at Liu Ming’s feet.
“Master, what happened?” Bone Scorpion raised its giant pincer and squeaked twice at the yin qi whirlpool. It seemed to be very dissatisfied with the yin qi being absorbed by the other.
“It’s okay, Demon Flying Skull is absorbing yin qi.” Liu Ming calmed Bone Scorpion and chuckled.
Whether it was Bone Scorpion or Jiu Ying Demon Flying Skull, the pure yin qi here was beneficial and harmless to them.
He could clearly feel that after the Demon Flying Skull swallowed the yin qi here, its aura suddenly became stronger with lightning speed.
After half an hour, Demon Flying Skull stopped the swallowing action without satisfaction.
At this moment, in the yin cave, the originally rich yin qi had become a little thinner. Some places in the cave that were originally covered by black gas were also clear, exposing large black stone walls.
These black stones were yin yuan stone which could continuously absorb the yin and evil energy in the underground and produce pure yin qi, but now the yin qi here had been almost wiped out. The yin cave here would have to wait for several months before restoring to its original state.
At this moment, the black gas around the Demon Flying Skull was a bit richer than before. Its aura had also increased by a lot, faintly reaching the Condensation Period later stage.
The sound of bone rubbing came out of the black gas. Demon Flying Skull continued to make strange ear-piercing metallic noises, seeming to be wailing in pain.
The Bone Scorpion on the side moved his body slightly restlessly and squeaked.
Liu Ming frowned slightly and released his Divine Thought again. At this time, he finally could communicate with Jiu Ying Demon Flying Skull. From the feedback received, it turned out that although it had swallowed a lot of troll bone and blood, it lacked yin qi nourishment, so it hadn’t been able to advance.
After waking up, it absorbed so much yin qi and finally began to mutate.
As the black gas surrounding the Demon Flying Skull rolled violently, purple glows suddenly burst out of the black gas.
After this lasted half an hour, the purple glows intertwined and formed a purple light curtain covering the Demon Flying Skull.
In the light curtain, the black gas tumbling more and more violently. It spun up and was sucked in by the Demon Flying Skull.
At this moment, the Demon Flying Skull had begun to change!
The small heads on both sides of Demon Flying Skull shook suddenly. After a flash of the green rune on the surface, they gradually turned into pure black color. Their eyes also revealed a faint green light.
Then, the three skulls made a strange scream at the same time. The small skulls on the sides had three bulging meat sacks after their flesh squirmed like something was going to pop out, making Demon Flying Skull look terrifying.
However, after meat sacks became the size of a bowl, they stopped abruptly.
After Demon Flying Skull’s three heads twisted and looked at themselves a few times, they showed a satisfying look at the same time. After one circling, they flew to the front of Liu Ming and let out a flattering call.
Liu Ming was surprised. He touched the head in the middle of the Demon Flying Skull with one hand. He instantly remembered the legend about the evolution of the Demon Flying Skull to Jiu Ying in the classics of the Savage Ghost Sect.
The current Demon Flying Skull had transformed into a level six demon, and its breath had reached the Condensation Period later stage. Its appearance looked even more like Jiu Ying that was recorded in the classics.
