Looking at the aura purifier that had absorbed the aura of the whole world and emitted a faint fluorescence all over the body, Luo Ziren was very curious about a question.

How long does it take to absorb 1 standard unit of spiritual power of the same attribute by yourself?

Luo Ziren turned on the stopwatch function of the psionic phone and started the timer before the official cultivation.

There is no difficulty in absorbing the same source spiritual power from the Aura Purification Instrument.

Luo Ziren only felt that the spiritual power that he had released could be quickly recovered in his thoughts, without any conflict and discomfort.

As a seventh-level Qi refining cultivator, there were only 14 meridians (spiritual power containers) refined in Luo Ziren's body.

In less than 1 minute of cultivation, he replenished the spiritual power he had lost during the day.

Then, it is a continuous stream of refining new meridians

This result surprised Lhotse Jen!

The existence of the Outer Dan Technique allowed him to almost save all his daily cultivation time, and he was hitting the bottleneck every moment!

"It's really worthy of being the top secret method of the Immortal Cultivation Research Institute, it's worth the money!"

Luo Ziren was excited, and felt that the spiritual power in his body was a little out of control, so frightened that he didn't dare to be distracted anymore, so he hurriedly got rid of distracting thoughts and cultivated seriously.

It's been a long time.

Luo Ziren heard a prompt from the aura purification instrument:

[The heaven and earth aura stored in this instrument is about to be exhausted, please replace the driving spirit stone as soon as possible!] 】

Luo Ziren broke away from his cultivation state, first glanced at the stopwatch, and found that the time recorded on it was just over 10 hours.

"So, 1 standard unit of heaven and earth aura can allow me to rush through the level with all my strength for 10 hours?"

"It's very effective!"

Luo Ziren was very satisfied with the performance of the Outer Danshu and the Reiki Purification Instrument.

After this cultivation, his cultivation progress has not changed greatly for a long time, and he has directly crossed a large distance.

"Cultivate 4 more times, and I can step into the eighth layer of Qi refining!"

"If there is no Wai Dan Technique, this process will require at least half a year of penance!"

"The cultivation efficiency has increased by nearly 40 times! And there are no aftermaths! ”

After Luo Ziren analyzed the results, he was stunned for a moment.

Doesn't it mean that the improvement effect of the Wai Dan technique starts at 10 times?

Why does it work so well on yourself?

As soon as this idea came out, Luo Ziren instantly thought of the answer.

His cultivation effect is good, purely because the spiritual root qualification is too poor!

Others cultivated with the help of the Outer Dan Technique, and it also took 5 days to break through from the seventh layer of Qi refining to the eighth layer of Qi refining.

But they do not use the breakthrough time of foreign objects, it may only be a month, two months.

Naturally, this proportion is not so exaggerated!

As for those geniuses who cultivated faster, they didn't need the Outer Dan Technique at all

After thinking about all this, Luo Ziren couldn't laugh or cry a little.

He quickly accepted reality.

The higher the promotion, the better, doesn't this just mean that your contribution is not in vain!

Luo Ziren's heart is happy.

But he glanced at the prompt text that popped up in the aura purification instrument, and his mood suddenly became low.

"Use it once and replace the driving spirit stone? That's an exaggeration, isn't it? ”

Luo Ziren, who has read the manual, already knows that the driving spirit stones used by the aura purifier are 2 medium-grade spirit stones.

Before the machine was turned on just now, the energy of the 2 spirit stones was almost full

In other words, if Luo Ziren cultivates once, he has to consume 2 medium-grade spirit stones?

The senior sister said before that because it is in a state of imminent war, the current market exchange price of the medium-grade spirit stone has reached 50,000 spirit stone coins per piece!

Cool 100,000 spirit stone coins at a time?!

Isn't that a bit outrageous!

Luo Ziren was shocked.

He suddenly felt that the Five Elements Quenching Spirit Method of Taiyi Immortal Academy was not expensive at all.

Even if the price increases by 10 times, it will save money compared to the secret method like a gold-swallowing beast like the Immortal Cultivation Research Institute!

However, the Wai Dan technique is not without its merits.

At least it can cultivate independently, and there is no risk!

It is said that before undergoing the transformation surgery of the Five Elements Quenching Method, the customer should be like a guinea pig, and be thoroughly studied by the high-ranking monks of the Taiyi Immortal Academy.

For Luo Ziren, this kind of thing is still very appropriate.

"Isn't it just a medium-grade spirit stone, I still have dozens of pieces, I'll talk about it when I'm done!"

"Anyway, almost all of the Waidanshu classics and auxiliary magic weapons are prostitutes, so I don't care about that!"

Luo Ziren thought about it and decided to let it go.

His cultivation had been stuck in the seventh layer of Qi refining for too long, and he couldn't waste time like this anymore.

Thereupon.

Luo Ziren first counted his inventory of medium-grade spirit stones and found that there were 45 left.

"After cultivating 22 more times, you should be able to reach at least the ninth layer of qi refining!"

Thinking of this, Luo Ziren directly replaced the driving spirit stone for the aura purification instrument, and then continued to turn it on.

For the next 3 days, Luo Ziren stayed at home, never even left the secret room for half a step, and when he was hungry, he would nibble on some dry food, and he had been practicing without sleep.

Finally.

In the early morning of the fourth day, Luo Ziren's body sitting cross-legged on the futon shook, and the two strange meridians and eight veins were completely refined by the majestic spiritual power and became a new "container".

The vast spiritual power that was originally crowded in the meridians suddenly found an outlet, and suddenly became enlightened.

At this point, Luo Ziren officially stepped into the eighth layer of qi refining.

"The strength of the spiritual power of the five elements has increased by 5 percent, and the spiritual power capacity has also increased by 5 percent!"

"Next, stabilize the realm for a few days, and then you can continue to cultivate!"

Luo Ziren glanced at his somewhat slimy body, and casually performed a cleaning technique to remove the dirt.

It stands to reason that the cleaning effect of the cleaning technique is quite good, but Luo Ziren always feels a little diaphragmatic.

He decided to take a hot bath to wash off the dirt thoroughly and relax his mind by the way.

Luo Ziren stood up, stretched his body, and put the treasure's aura purification instrument into the storage bag before leaving the secret room.

A few minutes later.

Luo Ziren soaked in the bathtub, swiped the communication jade charm, and checked the messages of friends.

Li Zhiwei didn't know that Luo Ziren was going to retreat, so she sent several messages to find him, and the latest one said that there was a gift for him, and asked Luo Ziren to contact her after he left the customs.

Why did this girl suddenly think of giving me a gift?

Luo Ziren thought about it and felt that he had no clue.

Anyway, Li Zhiwei lives next door, so it's good to ask her directly.

Luo Ziren sent a message to Li Zhiwei and made an appointment to meet her in 1 hour.

Next, Lhotze Ren checked other people's messages.

Zhong Daoxuan sent two messages, mainly to ask if Luo Ziren's cultivation of the Outer Dan Technique and the use of the Aura Purification Instrument were smooth, and whether he needed help.

Luo Ziren expressed his gratitude to the other party and politely declined his kindness.

Help is not needed.

Even if Luo Ziren now needs a large number of medium-grade spirit stones, he doesn't want to use Zhong Daoxuan's channels to obtain them.

He knew all the mysteries of the Wai Dan Technique.

If he mastered the consumption frequency of Luo Ziren's Zhongpin spirit stones, Luo Ziren's cultivation law was estimated to be like a blank sheet of paper in front of him.

So next, Luo Ziren not only would not ask Zhong Daoxuan and the dean for help, but even deliberately avoided them.

As for the reason, I just said that I didn't have time.

Having said that, where can you get a large number of low-priced medium-grade spirit stones, this is the problem?

Li Zhiwei's sister doesn't have to think about it.

Although the Li family has a big business, the number of spirit stones consumed every year is extremely exaggerated, and the medium-grade spirit stones are in short supply.

As for the others.

Luo Ziren remembered Senior Sister Liang Chaoxi.

Previously, he entrusted the other party to help purchase refining materials, and the cooperation was quite pleasant.

I wonder if she can help?

Thinking of this, Luo Ziren suddenly sighed.

In fact, for the acquisition of a large number of medium-grade spirit stones, the purchase channel is secondary.

The key is what to use to earn spirit stone coins?

The spirit stone coins in Luo Ziren's account now are not enough to buy 1 medium-grade spirit stone.

"I have to think of a stable and efficient way to make money."

Luo Ziren's eyes narrowed slightly, and he began to ponder his strengths.

First of all, it is not realistic to earn commissions on the machine.

Although he can easily forge a second-order spirit weapon now, where is this, the Immortal Cultivation Research Institute, almost every student can make a weapon, is there a market for the second-order spirit weapon he forged?

Even if there is a market, it won't make a lot of money, and it will be a waste of cultivation time.

Unless he can get some kind of out-of-print design drawings but it is still unrealistic, now that Xiandao technology is developed, so many large appliance factories are trying to compete for the market, but any product with huge market potential will be quickly copied by them.

You can't make a lot of money making tools.

Luo Ziren cultivates weapons, one is to master knowledge, the second is to practice fire control and body refining by the way, and the third is to forge weapons for himself to improve confidentiality.

Unless he goes to the black market specifically and sells the refined spiritual weapons to evil cultivators, he can make a lot of money, but he is not far from being wanted by the Dao Alliance.

If you want to make a lot of money, you can only think of other ways.

"Then again, compared to making weapons, puppetry, it's relatively unpopular."

"I don't know if I can make money by refining puppets and selling them."

"Not true. Puppeteer is originally an unpopular profession, the market size is not large, and it is unrealistic to make a lot of money! ”

"There is no way out of part-time work after all!"

"How can you make a fortune by earning money by crafting?"

Luo Ziren shook his head and secretly reflected.

At this time, Luo Ziren suddenly had an idea-

Isn't there still a few spots in my squad that haven't been sold!

If you can find a suitable customer, just by selling those 5 places (3 official + 2 substitutes), you can earn a few hundred medium-grade spirit stones, right?

Thinking of this, Luo Ziren's expression became serious.

He'll have to plan it out.

The other side.

The Office of the Dean of the Xiuxian Research Institute.

Zhong Daoxuan came uninvited again, sat on the sofa with a big grin, and chatted with his old father:

"Old man, why did you suddenly want to open it?"

"I thought that I would need to go bankrupt to get rid of the aura purification instrument in your hand!"

"I didn't expect you to loosen your mouth first, but it saved me a lot of effort."

Behind the desk, Zhong Beihai, who was reading a document in his hand, frowned:

"I don't remember seeing you!"

"Zhong Daoxuan, didn't you say that you were going to study the secret method of dividing the void that you got back recently, and you didn't have time to pay attention to me, an old man?"

"Why didn't you do it?"

Zhong Beihai didn't want to reveal the content of his conversation with Luo Ziren to his son.

On the one hand, it is to keep it secret for Luo Ziren, and on the other hand, it is to take care of his own face.

After all, Zhong Daoxuan is ready to come over to show off his good vision.

Dean Zhong has a good temper does not mean that he is shameless.

In front of his son, he still has to find a way to try to maintain his majesty.

"Hey, that thing is too complicated, I can't study it, I'm ready to give up."

Zhong Daoxuan replied as a matter of course, not at all ashamed of the three-minute heat.

Zhong Beihai couldn't help but clench his fists when he heard this.

This son of his, the spiritual root qualifications and comprehension are excellent.

But this nature is really hard to describe.

If it weren't for the efforts he and his wife worked hard to pave the way for Zhong Daoxuan, this kid would not have been able to marry in his early 30s.

Wrong.

As long as the husband and wife don't care about it, it's hard to say whether this kid has successfully built the foundation so far.

There is not the slightest piety in the whole way!

"Anyway, the Great Dao involved in the Dividing Void Secret Method has a very deep understanding, you are only in the Jindan stage, and it is indeed too difficult to study it in depth."

Zhong Beihai tried to calm down his tone, and said indifferently:

"Cultivate well first, and after you have cultivated the Yuan Infant, it's not too late to conduct research."

Zhong Daoxuan's face turned bitter when he heard this.

He knew the old man would say such things.

Although Zhong Dao's Xuanxin is not good, after all, he has also practiced penance for thirty years to achieve his current achievements.

For such a thing as cultivation, Zhong Daoxuan has long been tired of it.

He is not a pioneer soldier who faces life and death all day long, and he is not so persistent in improving his cultivation.

Now that he has married Dan, and let him continue to practice penance, he can't stand it!

I'm not a second-generation cultivator, and it's understandable that I've worked hard all my life.

I'm a well-known second-generation cultivator in Zhongjing, and I'm still working so hard, didn't I vote for this good tire in vain?!

Zhong Dao Xuannei thought confidently, and just dealt with the old man with a hmm-hmm.

Zhong Beihai also knew the character of this son, and after laughing, he did not continue the original topic:

"Then what is the situation now after Luo Ziren got the aura purification instrument? Have you ever cared? ”

"Of course I did."

Zhong Daoxuan came for this matter:

"After I sent someone to send the aura purification instrument over, I deliberately didn't send him any extra medium-grade spirit stones, I originally thought that kid would ask me to borrow spirit stones, and I even took the initiative to contact him."

"As a result, that kid hasn't opened his mouth to me, I suspect that he has a lot of medium-grade spirit stones in his hands!"

Zhong Beihai frowned slightly when he heard this.

He had read the archives and knew about Luo Ziren's family situation

Medium-grade spirit stones are not high-level cultivation resources that ordinary family students should have!

"Did the female classmate named Li Zhiwei lend it to him?"

"They seem to have a good relationship!"

Zhong Beihai asked indifferently, he had also seen Li Zhiwei's file.

"I don't know about that."

Zhong Daoxuan shook his head, and his tone was a little regretful: "I went to the Li family in Lingzhou to see, and the Jindan Beast Control Family still has the heritage, and there are more than one hundred and dozens of medium-grade spirit stones, and it is not impossible to take them out." ”

Zhong Beihai knew what Zhong Daoxuan was regretting.

This kid must have felt that he couldn't let Luo Ziren continue to owe favors to others, and felt that he had lost the investment opportunity.

"We can't have too utilitarian thoughts about treating Luo Ziren."

After Zhong Beihai reminded him vaguely, he changed the topic:

"Regarding Luo Ziren's combat team, there is still a shortage of manpower, you want to find a way to go to the 5th grade to pick a few outstanding students to fill in and improve the overall combat effectiveness"

"He may have a chance" (end of chapter)
