Mortal blood!

Lin Fan took out the copper bottle and put all the ten inferior Quenching Yuan Dan he had brought into it.

Soon, a strange light shone on the copper bottle.

The spiritual energy of heaven and earth around the thatched cottage was once again aroused.

In a moment, all ten inferior Quenching Yuan Dan turned into medium-grade Quenching Yuan Dan.

"It succeeded so quickly!"

Lin Fan looked delighted.

He quickly took out the enhanced medium-grade Quenching Yuan Dan.

He carefully compared it with the medium-grade Quenching Yuan Dan he had brought back.

He found that the medium-grade Quenching Yuan Dan he had enhanced with the copper bottle was no different from the medium-grade Quenching Yuan Dan he had brought back from the Merit Pavilion.

Moreover, the quality was slightly better.

This made Lin Fan's mind suddenly present a bolder idea.

"If I put these enhanced medium-grade Quenching Yuan Dan back into the copper bottle, will they become high-grade Quenching Yuan Dan?"

After thinking for a while, Lin Fan felt that his idea seemed to have no logical errors, so he directly put the ten enhanced medium-grade Quenching Yuan Dan into the copper bottle.

One breath!

Two breaths!

…

For a full cup of tea, the middle-grade Quenching Yuan Dan in the copper bottle did not move.

“Wait a little longer!”

Lin Fan was a little anxious in his heart.

But he kept persuading himself to be patient.

Another meal passed.

A crisp snapping sound suddenly came from the copper bottle.

See!

The originally crystal clear middle-grade Quenching Yuan Dan was completely cracked at this moment.

Intricate cracks covered the surface of the Quenching Yuan Dan.

Ten middle-grade Quenching Yuan Dans all became dim.

The medicinal power was gone.

“This…”

Lin Fan smiled bitterly and poured out the Quenching Yuan Dan that had been broken into powder in the copper bottle.

“It seems that something that has been strengthened once with a copper bottle cannot be strengthened again. Otherwise, it will be completely discarded.”

Lin Fan, who was extremely happy just now, was hit hard at this moment.

Ten middle-grade Quenching Yuan Dans!

Even if they were exchanged for lower-grade Quenching Yuan Dans, they could be exchanged for more than 120.

Now, it was destroyed because of his greed.

"There is one last middle-grade Quen Yuan Dan. I can't take such risks anymore."

After thinking it over, Lin Fan put the middle-grade Quen Yuan Dan into the copper bottle.

After strengthening it into a high-grade Quen Yuan Dan, Lin Fan was reluctant to take it and carefully put it into the medicine bottle.

At this time, Lin Fan's cultivation resources were very scarce.

In addition to fifty low-grade spirit stones, there was only one high-grade Quen Yuan Dan.

"The copper bottle can strengthen the pills, can it strengthen the spirit stones?"

Lin Fan was a little uneasy.

At this moment, he was almost at the end of his rope and could not stand any more tossing.

But, if he didn't take some risks, he might not have a chance to turn over in his life.

He struggled with himself for a long time.

Lin Fan gritted his teeth and threw a low-grade spirit stone into the copper bottle.

As a result, after two hours, the low-grade spirit stone in the copper bottle still did not change.

At this moment, Lin Fan basically figured out the purpose of the copper bottle.

First, the copper bottle is not omnipotent, and some things cannot be strengthened. For example, spiritual stones.

Second, items that have been strengthened once cannot be strengthened again. Otherwise, they will be destroyed.

Third, the copper bottle needs to consume spiritual energy to strengthen items. The more spiritual energy there is, the shorter the strengthening time, and vice versa.

"The lack of cultivation resources has seriously threatened my cultivation. I have to go to the sect market to exchange some elixirs."

The lack of cultivation resources put a lot of pressure on Lin Fan.

After packing up his things, Lin Fan left Piaomiao Peak and came to Qixuanmen Market with ease.

In order not to attract attention, he also disguised himself.

He looked at least three or four years older than he actually was.

If it weren't for someone who was very familiar with him, he wouldn't recognize him at all.

"Don't miss it if you pass by. Do you want to buy a combat Qi-refining puppet?"

"A ten-year-old Ganoderma lucidum costs thirty low-grade spirit stones. If you need it, come and have a look."

"Low-grade Quen Yuan Dan, you can buy one for only five low-grade spirit stones. It's selling at a low price."

Lin Fan walked while keeping an eye on the stalls around him.

Finally, he stopped in front of a middle-aged stall owner who was selling Quen Yuan Dan.

"How much is a medium-grade Quen Yuan Dan?"

The middle-aged stall owner's eyes swept over Lin Fan.

Seeing that he was young and dressed very ordinary, he immediately lost interest.

"Fifty low-grade spirit stones each!"

Lin Fan frowned slightly.

"Deal!"

With a casual throw, fifty low-grade spirit stones were neatly arranged in front of the middle-aged stall owner.

The shocked middle-aged stall owner was speechless for a long time.

"My friend, this is a mid-grade Quen Yuan Dan. One should cost at least 70 low-grade spirit stones, right?"

"According to the rules of the market, the deal is done when the spirit stones fall to the ground. Do you want to go back on your word?"

Lin Fan's expression turned cold.

This is the market of Qixuan Sect.

Most of the people who come here are disciples of Qixuan Sect.

If the other party really goes back on his word, he is not afraid.

After all, he is a disciple of Qixuan Sect's Piaomiao Peak.

Qixuan Sect must give him an explanation for the sake of face.

The middle-aged stall owner will be the one who will be unlucky.

The confrontation lasted for a long time.

The middle-aged stall owner saw that more and more Qixuan Sect cultivators were watching nearby, and his face flushed.

Gritting his teeth, he threw a mid-grade Quen Yuan Dan to Lin Fan.

"Here. I didn't expect you to be young, but worth a lot of money."

Lin Fan smiled and put away the mid-grade Quen Yuan Dan.

After most of the immortal cultivators who were watching the excitement nearby had left, he spoke again.

"You have a good eye. You can tell at a glance that I am worth a lot of money."

The middle-aged stall owner's face twitched.

I am blind, right?

I lost twenty low-grade spirit stones in vain.

Without waiting for the middle-aged stall owner to speak, Lin Fan smiled and said, "How many spirit stones does a top-grade Quenching Yuan Dan cost?"

"Top-grade Quenching Yuan Dan is too expensive. One costs seven hundred low-grade spirit stones. No bargaining."

The middle-aged stall owner looked serious.

Just now, he underestimated Lin Fan and suffered a small loss.

At this moment, he naturally did not dare to be perfunctory.

"Seven hundred low-grade spirit stones? What if I use top-grade Quenching Yuan Dan to exchange for low-grade Quenching Yuan Dan?"

"One top-grade Quenching Yuan Dan can be exchanged for one hundred and twenty low-grade Quenching Yuan Dan."

Seeing Lin Fan's calm eyes.

The middle-aged stall owner hesitated for a moment and said again: "If you really want to exchange, I will give you 130 lower-grade Quenching Yuan Pills."

The medicinal effect of 130 lower-grade Quenching Yuan Pills is naturally not as good as the medicinal effect of one upper-grade Quenching Yuan Pill.

But Lin Fan didn't mind.

As long as these lower-grade Quenching Yuan Pills are put into the copper bottle for strengthening.

That would be a full 130 middle-grade Quenching Yuan Pills.

The value has increased by dozens of times.

"Deal! I want spot goods."

"No problem!"

The middle-aged stall owner agreed happily.

Waiting for Lin Fan to throw a medicine bottle over.

The middle-aged stall owner carefully looked at the middle-grade Quenching Yuan Pill for a while, his expression was extremely excited.

"The quality of your upper-grade Quenching Yuan Pill is better than the general upper-grade Quenching Yuan Pill. I will give you 135 lower-grade Quenching Yuan Pills. If you want to trade pills in the future, come directly to me."

In order to attract repeat customers, the middle-aged stall owner actually gave Lin Fan five more lower-grade Quenching Yuan Pills.

This surprised Lin Fan.

After the transaction was over, Lin Fan quietly left the sect market.

In order to avoid being targeted, he deliberately took a long detour and returned to the thatched cottage on Piaomiao Peak.

In this transaction, Lin Fan had 135 low-grade Quenching Yuan Dan and one medium-grade Quenching Yuan Dan.

It seemed that he suffered a big loss.

Only Lin Fan knew that he had made a big profit.

Lin Fan took out all the pills and lined them up, his eyes lit up.

"After strengthening all these Quenching Yuan Dan, I will practice immediately."

"Within three months, I must become a Qi training level 8 cultivator."
