Half a month later, in the small courtyard of the pill shop, Mo Feiyu and Mo Qing'er were learning exercises from each other.

"Brother, be careful!"

Mo Qing'er looked proud, holding the Qingyun Sword and stabbing towards Mo Feiyu, and at the same time brought a whirlwind to roar, like countless wind blades.

"Carving insect skills!" Mo Feiyu smiled faintly, and then jumped up, and the Kongming fist quickly struck, and more than a dozen fist shadows were like flying stones, blocking all of Mo Qing'er's attacks.

Next, there was a loud noise, and the two people did not stop, but instead urged their spiritual power again and attacked each other.

This fight lasted for more than half an hour, and the two of them finally stopped.

"Brother, your strength is getting stronger and stronger!"

Mo Qing'er opened her cherry mouth slightly, gasping and said.

Mo Feiyu chuckled and tapped his sister's forehead and said:

"Say I'm strong, I think it's your ghost girl who is stronger, it's only been half a month, and you have actually broken through to the fifth layer of qi refining, your cultivation speed really makes me envious!"

Mo Qing'er smiled and said:

"No, haven't you also broken through to the sixth layer of qi refining, it should be said that the qualifications of both of us for cultivating immortals are excellent!

Speaking of this, Mo Qing'er's pretty face flushed slightly, and in her mind, a scene suddenly appeared in her mind where she would one day become a high-level immortal cultivator, and she and Mo Feiyu would live and fly together, and become a Taoist couple.

Mo Feiyu naturally didn't know what Mo Qing'er was thinking, when he heard his sister say that he was a genius in cultivating immortals, he couldn't help but smile bitterly, if it weren't for the cultivation of the Northern Darkness Refining Divine Technique and the taking of pills, I am afraid that he would still be hovering on the Qi refining layer now. If you want to talk about cultivating immortals, you really can't be counted.

Of course, being able to break through to the sixth layer of qi refining in such a short period of time, Mo Feiyu was quite satisfied with his cultivation speed.

But next, it's time to hit the seventh layer of qi refining!

For immortal cultivators in the Qi Refining Period, the seventh layer of Qi refining is an extremely clear watershed, and all monks who enter the seventh layer of Qi refining will have more than twice as much spiritual power in their bodies as they would be in the sixth layer of Qi refining.

Moreover, the immortal cultivators of the seventh layer of qi refining have an extremely terrifying ability, that is, they can release spiritual power and send and receive it freely.

If the spiritual power is released, you can easily condense the spiritual power in the body outside the body, instantly forming an energy shield, which greatly improves your own defense.

Moreover, when facing low-level cultivators, immortal cultivators who refine qi above the seventh level often only need to use spiritual power to form an energy field outside the body, and they will release a strong person's coercion, making the low-level cultivator's own aura disordered, even if the other party wants to make a move against him, he is more than willing and not enough.

Another and most important point is that the cultivators of the seventh level of Qi refining can cultivate the Imperial Weapon Technique.

If one cultivates the Imperial Weapon Technique, and has a magic weapon to help, the strength of the monk himself can often be more than doubled.

Against people, you can attack your opponent from a few feet away with just a magic weapon, and you don't give your opponent a chance to get close at all.

Because he killed Chen Ming in the duel, according to the rules, the magic weapon used by Chen Ming, the Red Flame Knife, was already owned by Mo Feiyu.

Next, Mo Feiyu only needs to increase his strength to the seventh layer of qi refining, with the help of the high-level magic weapon Red Flame Knife, and he can improve his strength again.

In this way, it is not impossible to kill Chen Zhen, who is at the ninth level of Qi refining.

"It looks like you need to refine the elixir!"

Thinking that the energy absorbed by taking the marrow washing solution in the past two days was getting less and less, Mo Feiyu sighed slightly.

The pulp washing liquid was a medicinal solution diluted by Mo Feiyu with water, so that he could take it directly without being affected by the violent energy in it.

And now, he has entered the realm of the sixth layer of qi refining, so naturally he doesn't have to worry about anything anymore.

Thinking of this, Mo Feiyu quickly found out an alchemy furnace that Mo Sheng had used, took out the prepared violet flowers and blue-leaved grass, and began the plan to refine the elixir.

"Brother, do you want to refine the marrow washing liquid again?Hey, how do you use the alchemy furnace this time?" Mo Qing'er asked with a little confusion.

After setting up the Dan furnace, Mo Feiyu said calmly:

"I just fused the medicinal powders with each other to refine the marrow washing liquid, but this time it is different, this time I want to refine the marrow washing pill, the real elixir!"

Mo Qing'er had never been interested in the way of alchemy, but she cared very much about what Mo Feiyu said, and she quickly remembered that Mo Feiyu had said that the marrow washing liquid was suitable for monks below the fifth level of qi refining.

"Brother, isn't it that when we reach the fifth layer of Qi refining, we don't need to take the marrow washing liquid, we can just take the marrow washing pill?"

"Well, that's right, the little girl is so smart, okay, you can cultivate by yourself, I'm going to start alchemy!" Mo Feiyu nodded slightly and said.

Mo Qing'er smiled and said:

"No, I'm going to guard you, you're refining here, I'll go to the door to protect you!"

Seeing that Mo Qing'er was really holding the Qingyun Sword and standing at the door, Mo Feiyu smiled calmly, and then began refining the Purifying Pill.

The way of alchemy is to seize heaven and earth and create, condensing the five elements of yin and yang. Not only does it need the strong spiritual power of the alchemist, but it also needs the power of extremely strong flames, and then wear the alchemy furnace ding, and go through various complex processes to condense the alchemy materials into Dan.

When refining the pill, don't be disturbed, which is also the reason why Mo Qing'er wants to take the initiative to protect Mo Feiyu.

The alchemy furnace in Mo Feiyu's hand was a three-legged small tripod, only the size of a wine jar, with a dark red surface and several pale green lines around it.

There are two openings under the small tripod, which surround each other inside the tripod furnace and communicate with each other, and the design is extremely ingenious.

And above the small ding, there is a realistic python entrenched, the head of the snake is raised in the middle, and the mouth is painted with a red letter, which is the tripod cover.

Around the lid of the tripod, there are dense holes, which are used to dissipate heat, in order to prevent the furnace from being too hot and the fryer appears.

Looking at this alchemy furnace, Mo Feiyu smiled and shook his head.

According to Mo Feiyu's research on the alchemy furnace, according to different grades, the alchemy furnace can be divided into four levels: low-level, intermediate-level, high-level, and superb, and the higher the grade of the alchemy furnace, the higher the level of the pill that can be refined.

Like what Mo Feiyu is using now, it is only the lowest-level alchemy furnace, even if his alchemy attainments are extremely high, at most he can only refine second-grade pills.

But fortunately, what Mo Feiyu wants to refine now is just a pill to wash the marrow pill, and there is such an alchemy furnace, which is enough to use.

After seeing the shape of the alchemy furnace, Mo Feiyu began to test the fire, first lighting a flame in the furnace ding, trying to control the size of the flame with spiritual power, the purpose is to familiarize himself with the heat operation in the alchemy furnace and facilitate the alchemy process later.

After counting the breaths, Mo Feiyu's eyes condensed slightly, and he probed into the Dan furnace with the power of his divine sense, trying to control the temperature of the flame with his divine sense and spiritual power.
