The so-called Qi Refiners are those Qi Refiners and Immortal Cultivators who have not yet been able to build a foundation in the scholar class.

Qi refiners, generally as long as they have the strength of more than three levels of qi refining, they can also play some low-level spells and spells.

Even low-level charms and spells are enough for Qi Refiners to easily kill the so-called martial arts masters in the Shu Clan's Han Sect, which is similar to the situation where firearms in modern society can easily shoot all kinds of kung fu masters.

And the talisman formed by low-level charms and spells can also be like those talisman energy shields in science fiction movies, so that ordinary people's swords and bows and crossbows cannot be easily destroyed, so they will naturally be invincible.

This is also the strength guarantee of the scholar clan of the Great Jin Dynasty, which can stand in a dominant position, and the children of the scholar clan with the innate spiritual vein, as long as they are not a lower-level innate spiritual vein like Zhu Lingwu, can enter the third layer of qi refining and play some low-level charms and spells after practicing for a few years, which is also very normal.

Of course, as long as the foundation is not built for a day, the body of the Qi Refiner is still a mortal body after all, and if he fails to release any charms and spells in time, he can be killed by ordinary people.

But there are not many opportunities for this kind of opportunity, because the children of the scholar clan with the strength of refining qi are generally guarded by martial arts masters of the Shu clan, just like in fantasy novels, Western magicians are protected by knights.

It is said that before building a foundation, Qi refining and cultivating immortals will encounter four hurdles, the first hurdle is to break through the third layer of Qi refining, so that there can be mana to drive low-level charms and release simple spells.

The second hurdle is the seventh layer of gas refining, the third hurdle is said to be the tenth layer of qi refining, and the first hurdle of zuihou is the thirteenth layer of qi refining.

In fact, the hurdle of zuihou is also connected with the foundation building pass, and when it reaches the thirteenth layer of qi training, it is also called a half-step foundation building in the mouth of qi refiners, and it can be regarded as a half-immortal cultivator.

The innate spirit vein grade in the body of the ordinary scholar disciples, as long as it is a mid-level quality, most of them will be stuck on the threshold of the seventh layer of qi refining, and most of the high-level quality will be stuck on the threshold of the thirteenth layer of qi refining.

The path of cultivating immortals is not easy, even if you are in the stage of refining qi, when you reach the fifth layer of qi refining, and then you want to go up, it is already difficult step by step, unless you are in the immortal sect outside the world, with the support of the sect's elixir, most of them can also reach the tenth layer of qi refining.

Zhu Lingwu's current cheap father is a Qi refiner of the seventh level of Qi refining, and he can be regarded as having some medium strength in the secular world, which is why he was able to go to Renzhi County, a small border county near the 100,000 Demon Mountains.

It is said that Zhu Lingwu's cheap father now has a mid-to-upper-level innate wood spirit vein, but until he is nearly sixty years old now, he can also cultivate to the seventh level of qi refining.

Although Zhu Lingwu was still not sure of the criteria for distinguishing the strength of the Qi Refiners, Zhu Lingwu's soul could still clearly feel the aura released by the Qi Refiners.

Before the Qi Refiner was able to build a foundation, the aura that he cultivated would be uncontrollably emanated, and for ordinary people, they could not see this kind of emancipated aura, and they could only sense a compelling aura, which made them instinctively have a sense of admiration for the Qi Refiner.

But for immortal cultivators, they can tell whether the other party is a qi refiner or not and what kind of spiritual power they are cultivating through this kind of spiritual energy that escapes from it.

Zhu Lingwu's cheap father in this life, Zhu Lingwu has also seen it several times, so Zhu Lingwu can sense the wood attribute aura escaping from his body.

It is said that the strength level of the other party can be roughly known according to the aura emanating from this qi refiner.

And now this Mongolian pharmacist may have used some method to restrain his aura, but it is a pity that he met Zhu Lingwu, a freak born from a lich, and Zhu Lingwu still sensed a trace of ghost aura emanating from the Mongolian pharmacist.

This inevitably made Zhu Lingwu wonder what kind of ghost cultivator this Meng Yao Master was, that is, the evil cultivator who is common in many novels.

That's why he was rejected by the decent immortal cultivation world, so he could only hide in a small border county like Tongshan County and hide his identity.

It's just that this shijie really has this so-called evil way?

Zhu Lingwu didn't know, the memory he had now and there was no information about this, as an eight-year-old child, what he could know was limited after all.

Even if such an evil sect really exists, it may belong to the struggle between those immortal cultivation sects outside the mortal world.

However, no matter who this Mongolian Medicine Master is, as long as he doesn't reveal his identity, he probably won't do anything to a scholar like himself.

Zhu Lingwu secretly thought in his heart, maybe this Mongolian pharmacist just wanted to continue to hide it by taking advantage of the identity of the Zhu family's slave.

In this case, it is best for everyone to be safe and sound with each other, but Zhu Lingwu dispelled the original idea of asking the Mongolian pharmacist about the debugging of those Baghdad batteries, he just wanted to keep this suspicious old man away from him as soon as possible, so that he could see some of his flaws.

When the Meng pharmacist heard this, he couldn't help but peek at Zhu Lingwu again, he bowed slightly, as long as he raised his eyes slightly, he could see the white and strong eight-year-old doll in front of him.

A strange look flashed in the cloudy eyes of the Meng Yao Master, but in a blink of an eye, he retracted again, bowed his head again and thanked him, "Thank you Xiao Yanei for the reward, as long as you don't delay Xiao Yanei's practice! It's just that the old man has always had a question in his heart, what is the origin of this magic weapon, what is the name, why can mortals such as me help Xiao Yanai to build it, so that there will be a statement in the future!"

This Mongolian pharmacist looked very curious, but in fact, he knew very well in his heart that this kind of Baghdad battery was not a magic weapon at all.

According to the research of Zhu Lingwu's original Shijie historical experts, the function of this Baghdad battery is only to gild the metal statue, and the power is not very large, so naturally it cannot be used as an attack weapon.

However, the Mongolian pharmacist personally created this kind of Baghdad battery, and he knew very well that this kind of Baghdad battery did not need any mana to drive, and it could naturally generate electricity, which really made him a little surprised.

He suspected that this kind of thing was originally a simplified imitation of some magic weapon, and what kind of method did anyone think of, this should indeed be something specially made for Zhu Lingwu to practice martial arts.

"Bold, how can you ask this! This is the mystery of the master's family, you are just a slave of the master's family, why are you asking so much!"

Before Zhu Lingwu could speak, Na Liangcai had already scolded loudly.

A trace of anger flashed on the face of the Meng Medicine Master, and he secretly said in his heart, damn boy, see how I will rectify you in the future!

"Don't dare, don't dare! It's just that the little people are really curious, so they ask! It's just that they have a name to brag about to future generations!"

On his lips, the Meng Medicine Master just pretended to be frightened, and his body seemed to bow lower......
