Chu Chen put away the human skin mask with great satisfaction, and carefully put it into the storage bag.

This is his new identity in three days!

After everything was cleaned up, Chu Chen began to practice alchemy.

The experience of watching Wuzong's alchemy before, it has been thorough, but it has only advanced to a second-grade alchemist, and it is probably not easy for me to advance to become a sixth-grade alchemist.

He took out the Erpin Dan Fang and equipped all the elixirs he needed, and then began to practice.

This second-grade elixir is the Treasure Flower Jade Dew Pill, a magical elixir that can enhance the cultivation of the realm of martial artists.

Chu Chen set up the alchemy furnace in mid-air, everything was ready, and suddenly released the fire in the center of the earth in his body, and this began the alchemy journey.

"The first is to smelt the medicinal materials, then to purify, evaporate, condense the pill, and collect the fire. ”

He went through the steps in his mind, and then he began.

This alchemy, a familiar feeling suddenly poured out, and the technique was extremely skillful, as if he had practiced the pill countless times before.

"That's right. ”

Chu Chen smiled secretly and understood the reason.

He has seen the martial arts alchemy experience thoroughly and thoroughly, knows all the steps in his chest, and has become a second-grade alchemist.

Now, practicing the second grade of the pill is naturally as easy as possible, without the slightest difficulty.

Soon, the refining of the second-grade pill treasure flower Yulu Dan was still successfully refined, and when the fire was closed, it only took an hour.

Chu Chen opened the Double Flame Xuan Furnace and found that there were five pills inside, so he couldn't help but smile and took out the jade bottle from the storage bag and put it up.

"Ding! You have refined the second-grade elixir, and you have gained experience of one hundred times one hundred!"

"Ding! Your second-grade alchemy has been completed, and now you are automatically advanced to a third-grade alchemist!"

Hearing this pleasant voice, Chu Chen was suddenly happy.

It seems that the hundredfold system is indeed powerful, and it has really advanced to the third-grade alchemist!

Go on!

Chu Chen muttered to himself, and continued to take out the Sanpin Dan Fang Glass Detoxification Pill, and put the main match aside.

This glazed detoxification pill is the antidote elixir among the three pins of pills, which can remove the poison in most of the great martial artist ranks.

Among the great martial arts class, it is very popular.

"The fire in the center of the earth, rise!"

After the fire of the center of the earth was released from the body, it was catalyzed by the aura, and immediately rose violently, burning under the double flame furnace.

"Polygonatum polygonatum, Poria cocos, 100-year-old ginseng ......"

While Chu Chen was thinking, he arranged these medicinal materials in order, in turn, and slowly put them in, after smelting these elixirs into juice, he began to purify, and then increased the firepower and began to condense the pill.

It didn't take long for the medicinal juice in the Dan furnace to have almost evaporated, and the appearance of the pill began to appear.

At this time, Chu Chen's face was extremely cautious, he slowly controlled the heat, slowly burned, and the little medicinal juice left in it almost evaporated.

"Collect Dan!"

Chu Chen snorted lightly, then abruptly took away the flames, and in an instant, the residual temperature in the Dan furnace heated the pills inside, and soon solidified into a rolling and glowing pill.

"Congratulations, you have successfully refined the three-grade pill Liuli Detoxification Pill, and gained experience of one thousand times one hundred. ”

"Congratulations, the third-grade alchemist has reached perfection and is now automatically advanced to a fourth-grade alchemist. ”

Hearing the system prompt, Chu Chen breathed a sigh of relief, he had already reached the fourth-grade alchemist, and he was only two realms away from the sixth-grade alchemist.

But Chu Chen knew that it was easy to go from the first grade to the fourth grade, but it was extremely difficult to go from the fourth grade to the sixth grade!

Just like the formation, he practiced many times before he was able to brush his proficiency to the perfection level, and thus advance to a higher level.

I'm afraid that this alchemy will have to be practiced a few times before I can gain enough experience, otherwise I won't even want to advance to a sixth-grade alchemist.

Therefore, Chu Chen asked the shopkeeper of the Treasure Spirit Pill Pavilion to prepare a few more medicinal materials in the fourth, fifth, and sixth grade pills in advance, so that he could use them for experience.

Sure enough, Chu Chen practiced three times, and with the blessing of the hundredfold system, it was equivalent to three hundred times before he advanced to the fifth-grade alchemist.

Immediately afterwards, he worked hard to refine the five-grade pill five times, and with the blessing of the hundredfold system, he reached the six-grade alchemist.

Six-grade alchemist!

Chu Chen looked at the dark night outside at this time, there was no moon, only stars and the chirping of crickets and insects around him.

"Go on!"

He made up his mind to complete the refining of the remaining five parts of the six or six pins of pills in one go.

Refining the six-rank pill was really a time-consuming thing, and after all five parts were practiced, it was already noon the next day.

The dazzling sun has reached the top of the head!

"Ding, your six-rank alchemy proficiency has reached the realm of Dacheng. ”

Hearing such a reminder from the system, Chu Chen couldn't help but smile with relief, then wiped the beads of sweat on his forehead, and sighed that his hard work for this day and night was not in vain, and he really arrived at the Sixth Rank Alchemist.

I already have the ability to refine the longevity pill!

Moreover, the current alchemy technique is not below the other party at all, even if it is a competition, it can be regarded as qualified.

"Without further ado, let's start practicing the formation!"

Chu Chen hurriedly put away the alchemy things, and then began to practice the five-grade defensive formation, the Great Sumeru Vajra Formation.

Why contact the defensive formation first?

He felt that everything was still based on his own safety, and he would first brush up on the proficiency of the defensive formation to perfection, no matter how the opponent attacked him, he could be safe and sound, so that he could be invincible.

"Great Sumeru Vajra Array!"

With a light drink, Chu Chen's hands were sealed, and he cast it.

He was delighted to find that he had reached the Dacheng realm in two hours.

Just when he was happy, Chu Chen remembered that when he went to the Dragon Soul Forest to collect the Yellow Fruit before, he peeked at the Giant Sword Gate Linghu Elder and Elder Shen hunting the Earth Vajra Ape, but he had been practicing for an hour, and he didn't stop once during this period.

Sure enough, the later progression was much slower.

After practicing for five hours, Chu Chen brushed the proficiency of the fifth-level defensive formation to perfection, and directly advanced to the sixth-level defensive formation Tiangang Golden Armor Formation.

It took a day to brush the proficiency of the Tiangang Golden Armor Array to the perfection realm, although it did not reach the point of forming a formation with one thought, but the speed of the formation was already very fast.

The defensive formation has been cultivated, and there are only six rounds of sixth-level killing formations left.

Before, he had practiced hard day and night, and brushed his proficiency to the Dacheng realm, but now he is only one step away from consummation.

At this time, it was already late at night, and it took him four hours to brush the proficiency of the six rounds of the Demon Demon Array to perfection.

"It's almost time, you have to hurry to Linhua Palace. ”

Chu Chen looked at the time, his heart sank, and he was ready to go out immediately to stop the six-rank alchemists from other places from refining the pill.
