"Whew, it's finally done!"

The wide cave was bright, and Li Chen looked at his masterpiece with a tired face, but with a hint of joy.

On the flat ground, countless exquisite indentations are burned, and within each node, there is a superb yuan crystal that exudes a crystal of warm luster.

Even if it hasn't been opened yet, as long as you stand here, you can feel the extraordinary strength of this formation.

Of course, with Li Chen's strength, it was not enough to build such a huge formation.

In addition to the limitations of their own conditions, most of them are still used ready-made arrays.

Not only did he scavenge the best array disks in the inventory of the Azure Clan, but he also took the Fire and Thunder Clan, as well as the high-level Half-Holy Spirit Ring, and used them one by one.

In addition, with tens of thousands of top-grade Yuan Crystals, although the entire formation is not top-notch, it is already extravagant to the extreme.

Even if it is a top-level demi-saint, I am afraid that he is reluctant to consume it like this, just for a breakthrough.

"This formation can maintain the 10,000-year-old spiritual milk, if you can't hold on, take a sip.

But remember, don't use it until you have to.

Even if you endure a few more breakthroughs, you have to persevere, this thing is at most a physical injury, but the spirit cannot be replaced!"

Coming to the center, Li Chen pointed to a high platform, on which a basin-sized groove contained crystal ten thousand years of spiritual milk.

Whining!

The Purple Pupil Demon Tiger licked Li Chen's palm and thanked him in a low voice, the killing intent that was originally stored in instinct had already dissipated in the previous battle.

"Okay, don't bother you, it's time for me to break through!"

After silently admonishing Wangcai in his heart, Li Chen left the cave and came to another place to make his own breakthrough.

Buzzing!

The formation light curtain then emerged, enveloping the Purple Pupil Demon Tiger and Wangcai, and also isolating Yiqiē from the outside.

As the saying goes, hearing is false, seeing is believing, and the way of illusion is only in a thought.

The Purple Pupil Demon Tiger knows that there is a white tiger bloodline in his body, this is real, it can't be completed, every qiē is nothing, this is illusory.

With the white tiger bloodline of prosperity as a guide, it is also virtual, but if it is turned into reality, it is a real sublimation.

Even a ferocious beast can understand this kind of breakthrough, it's really a long insight!"

After looking deeply at the curtain, Li Chen's heart seemed to open a door that had never been opened, and a subtle throbbing stirred up a ripple in the heart lake.

Although it is not obvious, it is like a spark of a spark, and sooner or later there will be a prairie fire.

The rest of the retreat breakthrough time was still as boring as before, and the extremely difficult barrier for other peers was nothing to Li Chen.

After all, not to mention all kinds of genius earth treasures, Li Chen himself broke through the cultivation realm, not the martial arts realm.

In just over a month, he successfully broke through to the middle stage of the Heavenly Void Realm, and the martial body also reached the middle stage of the eighth order.

Moreover, there are enough sixteen true dragon phantoms, and the foundation laid by years of hard cultivation can be called a thick accumulation every breakthrough.

Coupled with the blessing of various treasures, it is not surprising to have this kind of achievement.

But in that light curtain, the aura of the Purple Pupil Demon Tiger and Wangcai was still as silent as water, without the slightest change.

For the fierce beast, even with the blessing of various treasures and formations, the ontology is too large and the innate limitation, plus the realm that needs to be broken through is really too high, which also makes it difficult to far exceed Li Chen.

"Looks like I'm going to be here for a long time, and I'm going to have to find something to do for myself!"

He had expected this to happen, but Li Chen didn't worry too much, and took out a large mountain of bottles, cans and jade boxes.

These are all kinds of elixirs collected over the years, from high to low, everything is available.

Not to mention all, but the variety is complete, and it is beyond imagination.

Even if it is not enough, this elixir within a radius of tens of thousands of miles is at the mercy of Li Chen.

After all, this is the lair of the Purple Pupil Demon Tiger, but few people or fierce beasts dare to go wild here.

"Yuling Pill, I'll choose you!"

Thinking back then, the elixir of cultivating spirits that he had repeatedly performed miracles for himself, Li Chen felt a little emotional.

Originally, he still thought that the collection of martial arts, Dan Dao, instrument Dao, and array Dao was all involved, but it was still the old saying, when manpower is poor!

Even if he is extremely smart and diligent, he still only has some attainments in martial arts.

Legend has it that those peak powerhouses who have gathered all kinds of paths in one really can't imagine how to do it.

Even if Li Chen has never lacked demon pets around him, because of all the things, after the nurturing pill was used up, he never had the leisure to refine it again.

As a result, Li Chen's Dan Dao has been stuck in refining the sixth-order spirit pill, and as for the instrument path, except for condensing the Spirit Devouring Armor, there is no gain.

Not to mention the formation path, most of them are with the help of the formation disk, and they want to set up the formation by themselves, and his formation path is not qualified at all.

So, in the following days, Li Chen began an unimaginable alchemy process.

Boom Boom!

Huge explosions reverberated in the cave, accompanied by bursts of scorching paste and the smell of medicine.

Li Chen, whose face was dark, had no discouragement in his eyes, and once again threw one spirit pill after another into it.

Of course, this is still in the training stage, and there are all kinds of varieties to refine.

In the process of continuous alchemy, Li Chen's power to control fire became more and more subtle, and even led to his understanding of the law of fire.

Although his mind was immersed in alchemy and he didn't notice this, when he realized it, it would inevitably bring an opportunity for his own sublimation.

Years have passed, and in the alchemy day and night, the explosion in the cave has not sounded for a long time.

Airplanes!

Suddenly, the treasure light flashes, and the attractive aroma fills the air, making people feel like a spring breeze.

"Finally, there is no fryer for ten consecutive times, and the eighth-order high-grade cultivation elixir!"

Pinching a spirit pill that was as warm as jade, green all over, and the size of a dragon's eye, Li Chen smiled slightly, revealing a mouth full of ceramic-white teeth.

With his half-saint strength, refining the eighth-order high-grade spirit pill is indeed nothing, but you must know that this is only a few years of work, which is enough to imagine the amazing Cheng dù in it.

Moreover, there is also that amazing rate of becoming a pill, which is enough to show that his alchemy is not weak.

"There are thousands of avenues, others can walk a few more, and so can I!"

Close your eyes and groan for a while. Li Chen looked at the materials at hand, and his eyes flashed, "I want to see if with the true fire condensed by my Jiuyang Zhengang can be refined into an eighth-turn top-grade Dragon Fire Pill!"

It turned out that Li Chen had always been obsessed with the Dragon Fire Pill he had seen in the Fallen Star Sea Holy Star back then.

After all, the effect of Bao Dan is amazing.

Although the effect of the eight-turn mid-grade Fire Dragon Pill on him is also extremely high, Li Chen, who has always had a super desire for strength improvement, naturally wants to use the best treasure.

It's just that although the effect of this pill is amazing, the essence is far above the elixir.

Don't look at him, he can refine the top-grade cultivation elixir at will, but the difficulty of refining the eighth-turn dragon fire pill is definitely more than ten times worse, which is comparable to refining an ordinary eighth-order top-grade spirit pill.
