The aura that filled the dantian fused with each other under the drive of the battle technique, forming round after round of spiritual power fluctuations, constantly impacting the barrier of the inner wall of the dantian.

There are ten layers of barriers in the dantian, just like a balloon covering another balloon, the more backward the barrier becomes, the stronger it becomes, but under the dual action of the myelin cleansing pill and the battle technique, the barrier cracks and disappears one after another.

Six, eight... In the blink of an eye, the spiritual power fluctuations directly turned ten rounds, and the turbulent spiritual power fluctuations were backed by the huge aura of the Cleansing Pill, and slammed into the barrier on the inner wall of the dantian.

Listening to the "click", the barrier on the inner wall of the dantian collapsed again, and a large amount of spiritual power poured into the dantian, filling the newly opened space, and the prototype of a sea of qi gradually appeared in the center of the dantian.

At the moment when the Qi Sea hatch formed, a large amount of spiritual energy began to be absorbed into the center of the Qi Sea, and the Qi Sea continued to expand outwards until it covered the entire Dantian, and the edge of the barrier near the seventh layer of the Dantian gradually stabilized, and Youlan Mu was officially promoted to the sixth layer of Qi refining.

However, Youlan Mu's promotion did not end there, a large amount of spiritual energy adhered to the inner wall barrier of the dantian, hitchhiking on the sea of qi, rotating clockwise inside the dantian, constantly rubbing the inner wall barrier.

With the continuous influx of spiritual energy, the power of the ten rounds of spiritual power fluctuations superimposed became more and more powerful, not only his meridian bones were ravaged under the huge momentum, but even the strong dantian barrier was crumbling, and the effect of breaking through the wall of the battle spell was greatly exerted at this moment.

In the end, the dantian barrier could no longer withstand the huge pressure, scattered and cracked, the dantian expanded again, the sea of qi extended rapidly, occupying the newly opened up space in the dantian, and a large amount of spiritual energy emitted by the marrow washing pill was swallowed up, and even the spiritual energy within hundreds of meters around it frantically surged towards Youlan Mu at this moment, and since then, Youlan Mu has made great strides into the seventh layer of qi refining.

This process lasted for three whole days, and it was not until the effect of the pill was exhausted that Youlan Mu collapsed in the cave exhausted.

Originally, the Myelin Cleansing Pill was the elixir that Qi Li took when he was preparing to impact the Jindan Period, and Yu Lanmu was completely risking his life when he took the Myelin Cleansing Pill at the second layer of Qi refining, and the process of advancing exhausted his physical strength.

When Youlan Mu woke up, it was the fourth day of companionship, and he had been asleep for a whole day due to exhaustion. After waking up, the first thing he did was to probe his body, feeling the changes in his body, his eyes were wide, and he whispered, "Qi refining seven layers!" ”

This result surprised Youlan Mu very much, he actually crossed the sixth layer of qi refining in one fell swoop, not only cultivating the sea of qi, but also directly promoted to the seventh layer of qi refining.

You must know that many people in the Tianxuan Sect were unable to cultivate the Qi Sea, so they stagnated in the fifth layer of Qi refining, and the gap between the fifth layer of Qi refining and the sixth layer of Qi refining was like a chasm, blocking many cultivators from the door of the Great Dao, and he actually crossed this gap directly.

The sudden surprise made Youlan Mu a little ecstatic.

Youlan Mu carefully checked the changes in his body, the meridians were tough and stable, the flesh and blood were full of vitality, the space in the dantian was six times the original, and a cloud-like sea of qi slowly rotated in the center of the dantian, providing a steady stream of strength for the body.

Youlan Mu suddenly remembered something, and immediately untied the bandage on his right wrist, and the dark blue dark vein really grew along his wrist with the improvement of his realm, and five blue thin leaves also grew on the dark blue vein.

Youlan Mu licked his lips, the effect of this pill was no less than being empowered by a strong man, although the process was painful, but the result was extremely satisfying.

The fatigue after the promotion made Youlan Mu just want to find a place to wash off the sticky dirt on his body, and then go to the North Canteen to have a beautiful meal.

Youlan Mu used a bandage to cover the dark blue pattern on his right wrist again, and just as he was about to push away the rock at the entrance of the cave and leave the cave, suddenly he heard the sound of breaking the air outside, and then there were two soft sounds of "poof, poof", as if someone had fallen from the air to the ground and stopped outside the cave.

Youlan Mu was shocked in his heart, and couldn't help but secretly guess, "Could it be that the matter of hiding the Hades King Shanheding has been exposed!" ”

"Senior Brother Ji, are you sure it's here? It's so desolate, how can there be people. A somewhat familiar female voice came from outside the cave.

"Senior sister, don't worry, this is absolutely right, it was around here during the day that I noticed spiritual power fluctuations, and it was only at the level of the fifth layer of qi refining, in my opinion, that person must be seriously injured. If we can catch him and ask the sect for credit, the pills that Baihua Valley has rewarded will be ours. A cold male voice came, and Youlan Mu also felt as if he had heard this voice somewhere.

"Senior sister, you see there is a big stone here, and there are traces of dragging on the edge of the stone, that person must be in this cave." The man affirmed.

Youlan Mu's whole body tensed, his eyes narrowed slightly, the machete in his hand was slowly raised, staring intently at the big rock in front of him, he was a little unsure whether the other party was coming at him or at him.

If it was for Jie Li, then he had no need to fight hard, he was confident that no one else would see the corpse of Jie Li and the Hades King when he buried the mountain and river peak that day, otherwise he would not have survived until now.

Thinking in his heart, Youlan Mu immediately activated the secret method bloodline lurking, disguising the realm to the level of the third layer of qi refining, he didn't want to expose the matter of taking the marrow cleansing pill to advance to the seventh layer of qi refining.

"Senior sister, the situation inside is unknown, so don't rush in. Later, move the stone out of the way, hold the hole, and don't let the man escape. The man whispered.

"Senior brother, don't worry, I will never let that person escape from the hole."

"Okay, you go up and get the stone out of the way."

Youlan Mu heard the sound of the sword coming out of the sheath outside, obviously the man pulled the sword out, and then a light footstep gradually approached the big stone, and it could be judged that the two were about to attack.

Youlan Mu put the machete on his chest, and was about to announce the identity of his registered disciple, but before he could speak, an angry exclamation suddenly sounded on the opposite side of the big stone.

"What do you do!"

"Senior sister, can't you see it, of course it's going to kill you!" The man replied femininely.

Soon Youlan Mu heard the sound of the two fighting outside the cave, and he couldn't help but secretly wonder if the two were fighting among themselves, or if they didn't find out where the cave was at all, but just happened to have a murderous scene in front of him.

The fight didn't last long, and it soon became quiet again outside.

"Senior sister, you see that there are mountains and moons here, and the location is remote, is it good to be a place for you to be buried?" The man's voice sounded again, and this time the woman did not speak, apparently restrained by the man.

"Senior sister, why do you look at me like this, I can't help it. Li Xiaoran's slut promised me, as long as I cut off the relationship with you, she will form a Taoist couple with me, her master is Uncle Gu of Baihua Valley, the only third-level alchemist in Tianxuan Sect. Do you think I still have a choice? The man said unhurriedly, with indescribable tenderness in his words.

"However, senior brother, I am not the one who does not miss the old love, before sending you on the road, I have to let you enjoy it, I can't let you be a woman for nothing, but I don't know the beauty of the joy of men and women." The man's words began to become lewd.

Youlan Mu frowned, took a deep breath, the man outside actually wanted to rape first and then kill, and his ruthlessness can be seen. He retracted all his breath, and even the speed of the rotation of the qi sea in the dantian was reduced, and he made up his mind that he would never reveal his traces, and lurked in the cave.

He believed that with the other party's ruthless character, if he found that there was really a cave behind the big rock, and there was a person hidden in the cave, he would definitely kill people and kill people, and before he figured out the strength of the other party, Youlan Mu would not rashly clash with the other party.

However, this man's voice sounded somewhat familiar to Youlan Mu, he rarely interacted with people in the Tianxuan Sect, out of vigilance about the exposure of the identity of the Youlan Clan, he almost did not have any communication with other disciples, who could make him feel familiar, who could it be?

"Tear and pull~" The sound of silk being torn outside the cave sounded, mixed with the laughter of the man's **.

The more you listened to it, the more you felt that this person's voice was so familiar, he approached the edge of the boulder, looked out through a narrow gap on one side, and saw a young man dressed in white with his back to the cave, riding on a woman, tearing the woman's clothes, and kneading her delicate body wantonly.

Who the hell is this man? Youlan Mu looked the young man up and down, trying to find a trace of useful clues.

The young man in white smiled lewdly and shook off his long hair, Youlan Mu finally saw clearly who this human-faced beast heart was by the moonlight, and the other party was actually the outer disciple who cursed him for being killed by the eight-clawed octopus in the North Dining Hall, and it should be his female companion who was lying on the ground, Liu Ling.

Youlan Mu didn't have a good impression of either of them.

Just like to verify Youlan Mu's guess, the young man in white dragged the woman's hands and picked her up, the snow-white skin was exposed to the moonlight, which made people have some impulses to spurt blood and blood, and at the same time, Youlan Mu also saw the face that emanated, it was Liu Ling.

Youlan Mu shook her head secretly, this Liu Ling is not a lady, and it is no wonder that others are following a white-eyed wolf.

The young man in white hung Liu Ling up with torn strips of rags, and while laughing lewdly, he untied his belt, which needless to say.

Youlan Mu slowly retracted his gaze, he had no intention of being a hero to save the beauty, he would not expose his strength of the seventh layer of qi refining for a person who had nothing to do with him, just when he was about to wait for the matter outside the cave to end so that he could leave here without leaving a trace, suddenly he realized that something was wrong.

He looked out through the crack in the stone again, and immediately noticed a suspicious spot.

"How could it take so long to take off his pants, could it be that his belt couldn't be buttoned to death." Youlan Mu's eyes suddenly froze, "No, he's delaying time!" ”

Youlan Mu's heart jumped suddenly, and a sense of danger came to him in an instant, and he hurriedly released all his divine sense to explore the surroundings.

There was a soft "poof", and a green spirit sword suddenly burst out of the ground and went straight to his throat.

At the last moment, Youlan Mu forcibly twisted his body in a small space, narrowly avoiding the fatal sword, but his left arm was still pierced by the sword.

Youlan Mu, who had narrowly escaped, was furious, snorted coldly, kicked on the rock covering the cave, and kicked the big rock in the direction of the young man in white.

"Bang!" With a loud bang, the young man in white shattered the rock with one palm.

"I didn't expect you to react so quickly and be able to dodge that sword. However, it's time for you to come out and show up after you've been watching it for so long. The white-clothed young man recalled the spirit sword back in his hand and looked at the dark cave viciously.
