Lu Yuan pretended not to see the senior brother next to him who was gloating about his misfortune.

He came to the pool outside the alchemy room and quickly washed his face.

Suddenly, a familiar voice sounded from behind Lu Yuan.

"What's wrong, Junior Brother Lu, have you failed in making alchemy?"

Lu Yuan turned his head and found that Bai Dafei had appeared behind him at some point.

Looking at the smiling round face, Lu Yuan felt the urge to punch him for some reason.

Don't get me wrong, it's not that he had any ill intentions towards Bai Dafei, he was just a bit mean.

"Senior Brother Bai, why are you free to come to the alchemy room today? Don't you have to take care of the assessment of the outer disciples?"

Bai Dafei stepped forward and said with a smile: "Junior brother, you are overthinking. No matter what I say, your senior brother is the true successor of Dangu."

"Being an assessor is just one of the tasks I received. Now that the task is completed, of course I don't have to stay there anymore."

"Understood."

Bai Dafei looked at Lu Yuan at this time, and he didn't know what he thought of. He said kindly: "Junior brother Lu, looking at you like this, you must be trying to refine a new pill, right?"

"Senior brother, I am not bragging. When it comes to alchemy, although your talent and my talent are not as good as yours, I am better than you because of my rich experience."

"Tell me, junior brother, what problems have you encountered? Maybe senior brother, I can help you solve it."

Upon hearing this, Lu Yuan's eyes suddenly lit up.

Then he said, "Senior brother, when you were refining the marrow-cleansing pill, how did you control the temperature of the medicine?"

"How do we prevent them from being mutually exclusive and fuse together?"

"In the final condensation stage, how can you ensure that the power of the fused medicine stabilizes?"

Lu Yuan's series of questions directly stopped Bai Dafei.

Then he was stunned and said: "Junior brother, were you refining the Marrow Cleansing Pill just now?"

"Yeah, what's wrong?"

"What's wrong? There's a big problem here!"

"Wait a minute... You shouldn't have used your precious opportunity to redeem the foundation-building elixir for free on the marrow-cleansing elixir!"

Seeing Bai Dafei yelling, Lu Yuan became even more confused.

"I did exchange the recipe for the Marrow Cleansing Pill. Is there a problem with this?"

Snapped!

Bai Dafei slapped his forehead fiercely, his expression was speechless.

"No problem, let me tell you this. Although the Marrow Cleansing Pill is not as precious as the most precious elixir in the Foundation Establishment Period, the Foundation Establishment Pill, in terms of refining difficulty, the Marrow Cleansing Pill and the Foundation Establishment Pill

Dan is actually pretty much the same.”

"Of course, if the effect of the Marrow Cleansing Pill is similar to that of the Foundation Establishment Pill, then forget it. The key point is that this Marrow Cleansing Pill is recognized by all disciples as a useless pill!"

"Useless Pill?"

"Yes, it is the useless pill. Did you choose the pill recipe because you saw the explanation on the Marrow Cleansing Pill that there is a small chance of improving the spiritual root qualifications of the user?"

Lu Yuan nodded, this was indeed one of the key reasons why he chose the Marrow Cleansing Pill.

"Junior Brother Lu, you have been deceived!"

"You are not a true disciple, so you may not know how small the probability of the Marrow Cleansing Pill is."

"Let me tell you this, even if you take a hundred marrow cleansing pills, you may not be able to trigger the effect of improving your spiritual root qualifications."

"If you remove the aspect of improving your spiritual root qualifications, then there won't be much difference between the Marrow Cleansing Pill and the ordinary Yuan-Pui Yuan Pill."

"If you take a few more Peiyuan Pills, it's almost as good as a Marrow Cleansing Pill."

"Therefore, except for the marrow-cleansing elixir that the true disciples in the sect can receive every month, there are not many alchemists in the elixir valley who will refine this elixir."

"The reason is that the cost-effectiveness of refining the Marrow Cleansing Pill is too low."

"The refining is difficult, the medicinal materials are precious, and the effect is not obvious. It is obvious that whoever refines it is stupid!"

Forehead……

After Lu Yuan heard this, he didn't know what to say for a while.

Is it so difficult to trigger the effect of improving spiritual root qualifications...

Why did I feel it was so simple at first?

And what I was taking at that time was not the Marrow Cleansing Pill, but the Perfect Peiyuan Pill.

Thinking about it carefully, he could trigger the special effect of Perfect Peiyuan Dan so easily.

Everything must be attributed to his luck talent and lucky star.

If there is no luck talent and lucky star, then.

It is not easy for him to improve his spiritual root qualifications so simply.

However, Lu Yuan would naturally not tell others about his luck talent.

At this time, Bai Dafei seemed not to want to continue attacking Lu Yuan.

He sighed and said, "Hey, Junior Brother Lu, I won't tell you if there are many senior brothers. Just teach me a lesson."

"If you encounter this kind of thing again in the future, remember to ask your senior brother more often. I guarantee that I can save you some detours."

After saying that, Bai Dafei shook his head and left.

Lu Yuan looked at Bai Dafei's back, thoughtfully.

To be honest, if it were anyone else, this Marrow Cleansing Pill would not be very cost-effective.

But if it's him, it doesn't seem to be the case at all.

Don’t all the true disciples want the Marrow Cleansing Pill...

Lu Yuan keenly sensed an opportunity from these words.

If the disciples in the sect do not like the Marrow Cleansing Pill so much, then do I have a chance to redeem it from them?

You must know that if we simply talk about the effect of increasing the speed of cultivation.

Ten basic Pei Yuan Pills are almost as good as one Marrow Cleansing Pill.

If you use more than ten basic Peiyuan Pills for trading.

I think there should be many true disciples who would be willing to exchange with me.

After all, for most people, compared with the illusory spiritual root qualification improvement of the Marrow Cleansing Pill.

What they value more is increasing the speed of cultivation.

In this regard, Peiyuan Dan can perfectly replace it.

And the difference won't be particularly big.

If there is a chance, those true disciples should be more willing to exchange the Marrow Cleansing Pill for more Peiyuan Pills.

The more he thought about it, the more Lu Yuan felt that this plan was feasible.

Moreover, exchanging marrow-cleansing pills with the true disciples has another great benefit for him.

That was the improvement of his spiritual root qualifications, which gave him a perfect excuse.

Lu Yuan has been worried about a problem before.

That is how to answer when the Dream Demon Girl comes back and discovers that her spiritual root qualifications have improved.

And now this problem is solved, isn’t it?

Of course, this is the key reason why Lu Yuan wants to redeem the Marrow Cleansing Pill.

Or because he has a way to use the Marrow Cleansing Pill to 100% improve his spiritual root qualifications.

The Marrow Cleansing Pill, which is tasteless to others and would be a pity to throw away, is the best pill for him!

Thinking of this, Lu Yuan turned around and returned to the alchemy room.

There is no need to rush when exchanging Marrow Cleansing Pills, just take your time.

Right now, the most critical thing for him is to refine the Yuan-Building Pill, improve his skill proficiency, and learn to refine the Marrow Cleansing Pill.

[You have made an alchemy seriously, and your proficiency in metaphysical alchemy is 5...]

[You have performed firebending seriously, and your firebending proficiency is 3...]

[You released the Green Flame Technique once, and your Green Flame Technique proficiency is 10...]

...

Half a year later, Qingyunmen, Zhenzhuan Valley.

In the dead of night, with the moon and stars sparse, two sneaky figures arrived at the foot of the Zhenzhuan Valley one after another.

Not many people come and go here in the past, let alone at this hour.

The two people who appeared here at this time were dressed surprisingly similarly.

They were all wearing black clothes with their faces covered and their noses covered, obviously for fear of being recognized.

The two stood in the woods, looking at each other.

After a while, one of the men in black said: "Enough nonsense, where is the goods I want?"

The man in black across from him opened his storage bag and took out a medicine bottle containing pills.

Then he threw it directly to the opponent.

After getting the medicine bottle, the man in black opened it and smelled it.

"Yes, these are all good Peiyuan Pills. It seems that what you said is true."

With that said, he put away these Yuan-Pui Yuan Pills, took out a bottle containing Marrow Cleansing Pills from his storage bag, and threw it to the other party.

Lu Yuan caught the medicine bottle and opened it carefully to confirm.

That's right, of these two men in black, one is Lu Yuan and the other is a true disciple of the Qingyun Sect.

What they are doing at this time is the elixir exchange!

After Lu Yuan discovered the three marrow-cleansing pills stored in the medicine bottle, he said with satisfaction: "The number is correct, the transaction is completed, and we say goodbye."

After saying that, Lu Yuan and the unknown senior brother opposite left the True Legend Valley one after another.

The whole process can be called a fairy-tale version of underground trading, extremely mysterious.

When Lu Yuan returned to his alchemy room, he couldn't help but open the storage bag.

Not long after, three bottles containing marrow-cleansing pills appeared on the table.

Among these three medicine bottles, the minimum number is two pills and the maximum number is five pills.

Counting the bottle he just traded, there are ten marrow-cleansing pills in total.

Lu Yuan looked at the Marrow Cleansing Pill in front of him and narrowed his eyes slightly.

Calculating the time, Meng Ruyan, the dream girl who previously said she would be back in two years at most, should be back soon.

And with these marrow cleansing pills, even if she finds that her spiritual root qualifications have improved, she will be able to have a perfect explanation.

Don't ask him why he is so cautious.

When facing someone like the Dream Demon Girl, you can never be too careful.

Lu Yuan didn't want to one day become the first time traveler to be sucked dry by a witch, thus being nailed to the pillar of shame.

Therefore, he must be extremely careful to avoid being noticed by the enchantress that he may be out of control.

After all, he is not yet ready for a showdown with the witch.

Thinking of this, Lu Yuan put away all the marrow-cleansing pills on the table.

Because at this time, he did not have the conditions to take the Marrow Cleansing Pill.
