After sprinkling water and fertilizing the herbs and spiritual plants in the medicine garden according to Senior Brother Liu's instructions, Lu Chen entered the courtyard and closed the door.

According to Senior Brother Liu's introduction, the magic weapon of the mortal realm is called a magic weapon, and it can be divided into the first order to the ninth order according to its grade.

Immortal cultivators generally put their own magic weapons in storage bags, and more advanced ones in storage rings.

I have never heard of any immortal cultivator who can put a magic weapon into the sea of knowledge, although Lu Chen does not know much about the level of the magic weapon in the immortal cultivation realm, but the magic weapon that can enter the body of an immortal cultivator, plus so many immortal realm powerhouses want to get it, Lu Chen concluded that the family heirloom stone bead must be a great magic weapon.

Soon Lu Chen made another astonishing discovery, this bead can accelerate the speed of the spiritual energy in the body, there is a popular saying in the immortal cultivation world, the cultivation speed of the "Heavenly Spirit Root" is more than twice that of the "True Spirit Root", and more than twice that of the "Pseudo Spirit Root".

It can be simply understood that the "Heavenly Spirit Root" is the result of one day of cultivation, the "True Spirit Root" needs to be cultivated for two days, and the "Pseudo Spirit Root" needs at least four days or even more time.

Because the cultivation time is still short, Lu Chen himself can't say how much his cultivation speed can be improved with the help of stone beads.

Lu Chen named this bead "Qiyun Pearl", which means that after getting this bead, he began to have luck and embarked on the road of cultivating immortals.

What he himself may not have imagined is that in the countless tens of thousands of years since, his legendary stories have been circulating everywhere in the mortal realm, the spirit realm, and the immortal realm, among the three realms.

Late one night six months later, the clouds outside were thick, covering the bright moon, in the wooden house of the medicine garden, Lu Chen was cultivating as usual, suddenly, his whole body shook, and the spiritual power in his body gathered from countless positions in his body at this moment, like a river, swimming all over his body, blasting through countless meridians all the way.

When the complete cycle ended, the spiritual power in his body expanded on a large scale, and there was a lot more than before, and bursts of dirt appeared from the sweat pores of his body, and a sense of lightness turned into bursts of comfort, which made Lu Chen's spirit lift, his eyes suddenly opened, and a bright light that had never been seen before flashed in his eyes.

"Three layers of condensation!" Lu Chen suddenly found that his whole body was slimy, and he looked down and smiled dumbly, it is recorded in the three articles of condensation that if the qi refining period breaks through the third layer, it will be discharged from the remaining impurities in the body, which is a necessary stage for transforming the body.

Pushing open the door, it was midnight outside, Lu Chen's footsteps were light, he quickly walked out of the medicine garden, found a mountain spring, found a downstream location, took off his clothes and washed it, the black impurities were full of greasy, and it took a long time to wash it thoroughly.

After returning to the medicine garden after washing, Lu Chen lay on the bed, recalling a spell recorded in the third chapter of Qi refining in his mind.

The above details a spell called "Pyromy", which is a first-order spell that can be used as long as the third level of the condensation phase is reached.

Lu Chen continued to practice according to what was written in the book, raised his right hand, and raised his index finger straight, and soon after, at the point where the fingertip of the erected index finger was one inch high, a trace of spiritual power fluctuations suddenly occurred, and a few sparks appeared out of thin air, and the sparks gathered more and more, and finally synthesized a red fireball the size of a bowl.

Although the fireball was not large, a hot heat permeated the entire wooden house. But immediately, the fireball began to shake, and the flames on it began to shrink, and then turned into sparks and disappeared into thin air.

Although he didn't succeed in practicing, he was able to achieve this effect for the first time he cultivated, and Lu Chen was already very satisfied.

After another four months, Lu Chen successfully broke through to the cultivation of the fourth layer of qi refining, and mastered the introductory spell "Flame Technique" recorded in the "Three Articles of Qi Refining".

The power of this spell really didn't disappoint Lu Chen, and even far exceeded Lu Chen's expectations.

Don't look at the fireball of "Pyromy" is not big, but the terrifying heat contained inside it is almost indestructible to everything, and everything is incombustible.

Lu Chen once tried to make a hoe made of pure fine iron used in the medicine field, but after being hit by this fireball, it was melted into iron juice in the blink of an eye.

After seeing this inhuman terrifying power, Lu Chen felt quite satisfied with the speed of his cultivation and advancement this year.

According to the introduction of Senior Brother surnamed Liu, it generally takes one year for the "Heavenly Spirit Root" to cultivate from a mortal to the fourth level of Qi refining, the "True Spirit Root" takes two years, and the "Pseudo Spirit Root" takes at least three years.

And with the help of the Qiyun Bead, he cultivated for less than a year, and he practiced the fourth layer of Qi refining, and the speed was so fast that he had to secretly talk about the Qiyun Bead's anti-heaven spirit gathering function.

In fact, Lu Chen himself didn't know that after the mysterious stone bead was washed and the essence was removed, the hidden spirit root physique he now possessed was the other half of the reason why he advanced so quickly.
