After moving all his things to Xiao Jing's second-grade space bag, Lu Jin suddenly found an inconspicuous small black stone flake.

Hey, what is this, he didn't even notice it just now?!

This small black stone piece should have always existed in Xiao Jing's spatial bag.

Lu Jin took out the black stone shard, held it up and put it under the night pearl to observe it carefully, and found that the small black stone shards were engraved with many obscure symbols, Lu Jin guessed that this should be some kind of ancient language.

"What a!"

Lu Jin pressed his finger against the stone chip, and was scratched by the small stone chip that looked extremely dull!

He didn't notice a trace of blood silently merging into the black stone shards, and at once smashed the stone shards against the stone walls of the cave.

A large crater was smashed into the stone wall, but the small black stone chips were unharmed.

This aroused Lu Jin's interest!

What can make the son of the master of the Heavenly Machine Pavilion look at it must not be ordinary!

Lu Jin picked up the small black stone chips from the ground again, and then studied them.

But he really couldn't understand the symbols engraved on it, so he decided to wait out of the cave and go to Tianyuan Pavilion Master Fuyun to investigate!

Lu Jin took a break, took out a rejuvenation pill from the space bag and took it, and then meditated cross-legged.

The small cyan droplets in the dantian swirled drippingly, and the wound on Lu Jin's abdomen healed at a speed visible to the naked eye, and his state returned to his heyday.

This month, he plans to break through to the middle stage of the Great Perfection of the Qi Condensation Period, and then go to participate in the trial of the disciples of the Beicang Sword Sect!

So before he started, he was going to refine a batch of pills to cope with his future cultivation!

Taking out a large number of medicinal materials purchased by Poria cocos and Ganoderma lucidum for himself, a quarter of the cave was filled in an instant!

Lu Jin placed the black iron furnace in front of him, then spat out a cyan flame from his mouth, and slowly floated into the fire trough under the furnace.

When the black iron furnace was heated and there was a buzzing sound, Lu Jin waved his hand, and a medicinal herb of the Rejuvenation Pill fell into the furnace at one time, covered the lid, and began to refine.

"The host has successfully refined a resurrection elixir, with a proficiency value of +1 and an achievement of 44/100!"

"The host has successfully refined a Resurrection Elixir, with a proficiency value of +1 and an achievement of 43/100!"

"The host has successfully refined a rejuvenation pill, the proficiency value is +1, and the achievement reaches 45/100!"

......

A burst of prompt sounds came, and Lu Jin's alchemy beginner achievements were getting higher and higher, and there were more and more pills that had been refined floating in mid-air around him!

"The host refines a resurrection elixir, the proficiency value is +1, and the achievement reaches 100/100!"

The lid of the medicine stove opened, and a turquoise elixir floated in midair.

"The host alchemy beginner achievement is full and can be upgraded, is the host willing to spend 1 currency to upgrade!"

Finally made up for the achievement, and Lu Jin, who was happy, immediately cooled when he heard this prompt from the system!

What, you still need a currency to upgrade your achievements?!

It's really a system made by him, it's too bad!

Lu Jin immediately took out the Boiling Blood Muscle Pill from the space bag, and then asked the system:

"System, can I recharge currency?"

"Ding! Currency Detected Exists, Current Status, Rechargeable!"

"May I ask if the host chooses to recharge!"

Sure enough, the four pins of pills can be recharged as currency!

Lu Jin, who had been verified, had a little spectrum in his heart, and then said decisively:

"Confirm the top-up and spend 1 currency to upgrade the Alchemy Beginner achievement!"

"Ding!1 currency recharge is successful, and the host's current account balance is 2 currency!"

"Ding! Alchemist Beginner Achievement Upgrade Completed, Currency -1, Host's Current Account Balance 1 Currency!"

Tips: The host can refine the second grade and below elixirs, with a success rate of 100%

"Host: Lu Jin

Realm: The beginning of the Great Perfection of the Condensation Period

Mental method: Three elephant formula, Tianluo mental method, galloping energy, body building method, Pei Yuan Gong

Special Ability: Exclusive (Upgradeable with Currency)

Achievement: Alchemist Achieves Small Success (Currency Upgradeable)

Recharge Coins: 1

Exchange Value: 20 (temporarily unredeemable)

System Level: Yellow (Temporarily not upgradeable)"

Turning off the panel automatically displayed by the system, Lu Jin's heart set off a stormy wave!

The second grade of the pill, the success rate is 100%?!

Now Lu Jin has a bold idea in his heart!

If he had risen higher and higher to become an alchemist, wouldn't he be able to refine the Four Rank Pills without restrictions in the future?

The words of the currency are endless!

Is this a bug in the system?!

Although it was only a preliminary idea, Lu Jin's heart was already happy!

After stabilizing his mind a little, Lu Jin still had half of the medicinal materials left in his hand, and he planned to refine them into pills!

"The host has successfully refined a resurrection elixir, with a proficiency value of +1 and an achievement of 1/300!"

"The host has successfully refined a rejuvenation pill, the proficiency value is +1, and the achievement reaches 2/300!"

"The host has successfully refined a resurrection elixir, with a proficiency value of +1 and an achievement of 3/300!"

......

With one tireless prompt sound after another, Lu Jin's elixir was finally refined!

The pills suspended in mid-air around Lu Jin were densely packed, and the entire cave exuded a medicinal fragrance.

Even some spirit beasts were attracted by this rich medicinal fragrance, but they were blocked by the miasma of poisonous pools.

Now Lu Jin has a total of 170 Rejuvenation Pills and 100 Rejuvenation Pills, which can be described as a lot of money!

Putting all the pills into the space bag, Lu Jin's face that had already removed the mask showed a serious look.

Now, he is about to begin to break through to the realm of the middle stage of the Great Perfection of the Qi Condensation Period!

Lu Jin first swallowed three Resurrection Pills in one go, and a thicker aura mist appeared in front of him in an instant.

Not in a hurry to absorb it, he took out two spirit stones from the space bag and put them in his hands, and Lu Jin began to urge the small cyan water droplets in the dantian to rotate with all his might!

In the cave, a small whirlpool of spiritual energy appeared with Lu Jin as the center, and the spiritual energy mist and the spiritual energy in the spiritual stone in his hand were inhaled into the dantian by Lu Jin with hunger.

After taking three more spirit pills and taking out two spirit stones, Lu Jin's movements repeated the cycle indefinitely!

In this endless aura absorption, there was even an abnormality in the sky above the cave where Lu Jin was, and the aura in a radius of more than ten meters in the area was dragged over.

This state lasted a whole day!

Even the spirit beasts in the depths of the Ten Thousand Ghost Mountain Range noticed the abnormality and opened their sleepy eyes one after another.

Not enough, still not enough!

Lu Jin, who had taken three more spirit pills, threw away the spirit stones that had been turned into ordinary stones by absorbing the spiritual energy, and thought to himself.

Although the color of the small water droplets in his dantian is more turquoise, the absorption speed is too slow!
