Return to your own cave house, swallow a Bigu Dan, and the retreat officially begins.

Bigu Dan, Qi Refining disciples no longer need to eat and drink for three months after taking it. Ye Yan thinks that this thing is the most chicken elixir. The sect has a supply of chicken, duck, fish and meat, so there is no need to purchase it yourself. Spend ten taels of silver to buy a servant girl, and let the servant girl cook whatever she likes. Bigu Dan is worth three lower-grade spirit stones, and it is more than enough to eat a servant girl at every meal!

Immortal cultivators use their bodies as a furnace, absorbing the spiritual energy between heaven and earth bit by bit, refining it into their own mana, and then using the mana to transform their bodies, absorbing more spiritual energy, and repeating the cycle. Breaking through the shackles of the body is like a drop of water piercing through a stone, and a disciple with excellent talent is like a boat sailing against the current, condensing bit by bit over the long years.

Ye Yan's situation is a little different, he can invoke the mana of the ghost slave, although the mana of the ghost slave is limited, but he is better than the number. The combined mana of more than 3,000 ghost slaves is equivalent to a disciple of the fourth layer of qi refining. Therefore, he doesn't need to waste time absorbing spiritual power, nor does he need to bother to convert spiritual energy into mana, and directly invoke the mana of the ghost servant to transform his body!

The mana of the three hundred ghost slaves was instantly emptied, turning into a surging dark torrent, pouring into the body, and the place where it passed was like destroying the withering and decaying, and the mana was rushing in the body, surging towards the dantian quickly.

The change that was originally a drop of stone piercing, under the support of the majestic mana, became like a bamboo! In an instant, Ye Yan was pushed to the brink of a breakthrough.

It's too unrestrained! Ye Yan was shocked into a sweat, and broke through, although he required sufficient mana, but he didn't dare to be too violent, and he couldn't hurt himself. I have abundant capital, and a breakthrough is a certainty, and I am not in a hurry for a moment.

Ye Yan didn't dare to rush too violently, forcibly controlling the mana to flow in slowly, so that everything became gentle, when the immortal cultivator broke through, he was trying his best to urge the mana, but he was constantly braking, after repeated tug-of-war, under the impact of the second wave of mana, he successfully broke through to the third layer of qi refining. Halfway through, he drained the mana of two hundred ghost slaves.

Sweat soaked through his clothes, and Ye Yan breathed a heavy sigh of relief, "What the old monster said is true, the ghost servant's help to the monk is really powerful!"

If the old monster of Zhantian heard his sighs, I am afraid that he would burst into tears on the spot, the ghost servant's help for cultivation is powerful, but it is far from being so powerful. He had drained the mana of five hundred ghost servants! The other disciples had only invoked the mana of one ghost servant, and they already thought that the ghost control technique was an existence against the sky.

Time only passed two hours, Ye Yan's body was soaked with sweat, not how difficult it was to break through, the sweat all over her body was shocked. People's breakthrough is like climbing a dangerous peak, and his breakthrough is like going downhill from a lonely peak, which can be described as frightening step by step.

Of course, although the process of breakthrough is extremely dangerous, Ye Yan's advantage is obvious, once other disciples break through, not only their own mana, but also the pill will definitely be consumed. And Yeyan still has a strong capital, and there are more than 2,000 ghost servants with mana to squander.

It's not night yet...... Taking advantage of an hour to stabilize his mind and calm down, Ye Yan was about to move, and decided to break through the fifth layer of qi refining.

With the lessons of the past, Ye Yan decided to take it step by step, only draining two hundred ghost servants in the early stage, and the control was much smoother than before, and the skillful control not only reduced the risk, but also reduced the loss of mana.

Waiting for the mana in the galloping body to gradually weaken, he invoked the ghost servant mana for the second time, then the third, fourth, and fifth batches, each batch of two hundred ghost servants. Impacting the fourth layer of qi refining has increased the amount of mana required several times compared to the third layer. even made him worry about the dilemma of insufficient mana, but fortunately, he had more than thirty low-grade ghost slaves, which was barely maintained.

When the sky was bright, Yeyan ushered in a breakthrough again, cultivating immortals, and every time he broke through the realm, it was like being reborn and reborn from a cocoon. Not only has the physique improved, but the mana is also agitated, and it is ten times stronger than before entering the level. Every time the realm is improved, the mana skyrockets several times, and the higher the level, the more this situation is amplified, and correspondingly, the higher the difficulty of breaking through. Ye Yan's approximate estimate is that to be promoted to the fifth level of qi refining, the most conservative estimate is that more than 30,000 ghost servants are needed, and it is still far from enough to enslave all the ghosts in the soul ring, so he has to go ghost hunting again. It's a pity that I'm still thinking behind closed doors, and my actions are restricted, so I can only wait patiently.

If the old monster knew the stinky boy's crazy cultivation ideas, he wouldn't be able to vomit three liters of blood on the spot, but then again, if the old monster had such a demonic talent, he must have cultivated like this, and he would never kill to absorb the aura step by step.

If it is a retreat, Ye Yan can now get out of the customs with a beautiful scenery, but he can't get out, the exit of the cave is prohibited, and there are law enforcement disciples guarding it, to borrow the words of the old monster, you kid can't fly with wings!

Yeyan was depressed for a while before he gradually calmed down, and Bigu Dan also swallowed it, and he couldn't get out anyway, so he just found something to pass the time.

After making up his mind, Ye Yan fell asleep, and when he woke up, it was dark, and he began to repair the magic weapon.

First of all, the sword pills, this set of sword pills selected is of high quality, and the formation is used in a decent manner, so there is no need to make major changes, so it can save a lot of mana and time.

Before the repair, Ye Yan enslaved three hundred ghost servants again, he divided the ghost servants into a group of three hundred, and when he called the mana of a group of ghost servants, the remaining ghost servants stayed in the soul ring to cultivate, so they took turns to change, no matter how long the time was consumed, he was not afraid of insufficient mana.

After the formation of the cycle of good surnames, Ye Yan turned to the pursuit of speed, and in the current cultivation stage, the limit mana output was adopted, and the repair speed suddenly increased by more than three percent, and correspondingly, the mana use efficiency plummeted. Anyway, with endless squandering mana, he didn't care.

Rao is like this, it still takes two days to repair this set of sword pills, and it is two days that are sleepless.

After the promotion, the sword pill has become a top-notch set of superb magic weapons. The originally dim and astringent sword pill seemed to be reinfused with life, and the fluctuations of energy slowly flowed on the surface of the sword pill, and after urging the mana, a strange light flickered, and it moved rapidly under the drive of divine thoughts, which was dazzling. With this perverted speed alone, it was a deadly threat to the monks, and when driving the sword pill, the rapid burning of mana showed that its destructive power was extremely outstanding.

The name of this set of sword pills should be 魑魅魍魉.

As a refining master, you can not only perceive the material and formation of the magic weapon, but also feel the mind of the refiner.

After resting for a day and night, Yeyan started to repair the Hyakki.

The material of the Hundred Ghost Banner is very ordinary, but it is a top-grade magic weapon itself, and with the effect of the Holy Demon Bloodline, no matter how bad it is, it has been upgraded to the best magic weapon.

The discerning Ye Yan insists that this is a pseudo-superlative. In the eyes of ordinary monks, ritual weapons are divided into lower grade, middle grade, upper grade, and best grade. The same is true for spiritual weapons, but the master refiner can tell that they are also superb, and the difference between the advantages and disadvantages is also very different.

If the Hundred Ghost Banner is a pseudo-top-grade magic weapon, the last remaining whip definitely has the potential to be promoted to a super-best spirit weapon.

Compared with the ease of repairing the magic weapon, repairing the spiritual weapon is a huge project.

The most deplorable thing is that the original refiner actually added Wu Jinsha, and it was this precious material that caused the whip to become a low-grade spiritual weapon. To achieve perfect ascension, it is necessary to separate the Ujinsha.

The cultivation of the fourth layer of gas refining separates Wujinsha...... , three months doesn't seem to be enough, and the scum scolds her mother on the spot!

After three months of closed-door thinking, Ye Yan rushed out of the cave in a frenzy, with dark eyes and a decadent expression, and he couldn't see the radiance that should be seen when he broke through the realm.

The law enforcement disciples he met along the way kept congratulating, and the most celebratory event for the monks was the ascension of his realm. It's just that Yeyan's cultivation is too low, and it feels like celebrating a four-year-old child's birthday.

The old man had explained, and he saw him immediately after leaving the customs, and Yeyan didn't dare to delay and went quickly.

"Stinky boy! It's only three months of hard work, and it's really broken through for Lao Tzu!"

Although the old monster let out cruel words at the beginning, telling Ye Yan not to cultivate to the third level of qi refining, and not to come to see him, but in the bottom of his heart, he didn't dare to have much expectations, at best it was a spur. You know, this kid only got to the second layer of gas refining for seven years, and he broke through to the third layer of gas refining within three months, is it obviously difficult for a strong man?

Who would have thought that this kid would really break through! and jump two floors at a time!

Changing to other disciples to break through, it's not a matter at all, the old monster doesn't even bother to ask, this kid's situation is different, it's like an iron tree blooming!

Jumping from the second layer of qi refining to the fourth layer, don't underestimate the difference between these two layers, in terms of Ye Yan's age, now that he has reached the fourth layer of qi refining, his talent is already good, at least he can rank below the middle!

This kid jumped two floors in three months under the spur of this seat, which shows that he has strong explosiveness, and his talent is at least ranked above average, or even superior!

"Your kid used to improve slowly, and he was buried by the Ethereal Peak!

Seeing that the old monster of Zhantian was in a mess with excitement, Ye Yan wondered, it was only promoted to the fourth layer of qi refining, as for the old monster to be so excited? Only he knew that he had thought about it behind closed doors in the past three months, and he was mainly repairing the spiritual weapon, and it only took one night to improve his cultivation.

Not only Ye Yan wondered, but the law enforcement disciples present were really depressed! What kind of place is the Law Enforcement Hall? Jin Dan walks all over the ground! The ancestor is not as good as a dog! This kind of analogy is not exaggerated at all. If it weren't for the terrifying power, why would the ancestors of all forces be suppressed. The Law Enforcement Hall is not a place to cultivate disciples, but a violent institution of a sect, to join the Law Enforcement Hall, at least you must have the strength to build the pinnacle of the foundation, and this is because of the benefits of joining the Law Enforcement Hall, there is a Ascending Pill.

The disciples who built the pinnacle of the foundation used the Ascending Heaven Pill to attack the Golden Pill had at least seventy percent of the certainty of success. Therefore, although law enforcement disciples are required to build the foundation at the peak, in the law enforcement hall, it is difficult to see a disciple at the peak of foundation building, and the minimum level is also at the Jindan level. This kid only refined qi at the fourth level after breaking through, and he was not qualified to join the Law Enforcement Hall, so he was so favored by the elders, why did he?

In the stage of developing new books, ask for recommendations, and add collections to those who are too thin
