Chapter 384: Extreme Imperial Pill

Return to the Great Yan Empire.

Yi Chen's consciousness quickly found a swamp crocodile deep in a mountain, who dared not continue to practice.

"Your Majesty!"

Seeing Yi Chen appear, the swamp crocodile finally relaxed a little.

It could already vaguely feel that if it continued to practice, it would face the test of the Great Dao of Heaven and Earth.

If Yi Chen had not intended to give it a great opportunity to make it the first demon to pass the tribulation, it would definitely choose not to practice anymore and slowly consume it.

When its lifespan is about to run out, it will make another desperate effort.

"Continue to practice until the moment when the heavenly tribulation is about to appear."

Yi Chen gestured.

The swamp crocodile is greedy for life and afraid of death, but he knows when to be decisive.

He did not hesitate and immediately spit out the crystal core.

The demon power is running.

The rich spiritual energy of heaven and earth, like a whirlpool, is constantly rotating and penetrating with his crystal core as the center.

Yi Chen's consciousness can sense that in the Great Dao of Heaven and Earth, the power of the law is being pulled by the qi and is constantly fluctuating.

As the swamp crocodile continues to practice, the fluctuations are getting bigger and bigger.

Until this fluctuation reached its peak and was on the verge of an explosion, the swamp crocodile stopped practicing.

"It seems, not so good..."

Yi Chen was a little surprised.

He had experienced the tribulation, and he was the first cultivator of the human race to do so.

According to his feeling, the swamp crocodile, as the first demon to undergo the tribulation, should be about the same strength as when he did.

But judging from the fluctuation of the law power caused by the swamp crocodile, it seemed to be much weaker than when he did.

It seems that even if they are the first tribulation survivors of the same race, their strengths also vary.

Perhaps because of the large population of the human race, as the first tribulation survivor, the test of heaven is stronger than that of ordinary first tribulation survivors.

As for whether it is the same as guessed, Yi Chen does not know.

He did not focus on this.

The strength of the swamp crocodile's tribulation was much lower than he expected, which was a good thing.

According to his original plan, if the swamp crocodile's tribulation strength was as high as his, he would have to combine the defense capabilities of various demon races to help the swamp crocodile develop a set of powerful defense capabilities.

At the moment, it doesn't need to be so troublesome. He only needs to refine a few immortal pills that he had conceived long ago.

The first demon to break through the heavenly tribulation, although the difficulty is equally terrifying, and the success rate is so low that it is outrageous.

But this is because he has no one to rely on and can only rely on his own ability to overcome the tribulation.

With the spiritual pill refined by Yi Chen, it is completely different.

"Okay, wait here!"

Yi Chen explained and returned to the flying magic weapon.

All kinds of spiritual minerals were taken out from the storage ring.

In just over ten hours, he successfully refined an immortal alchemy furnace.

This alchemy furnace is powerful and can improve the quality and stability of the pill.

The only thing missing is that Yi Chen has no time to study the formation to improve the various functional effects of the alchemy furnace, and just arranged the amplification formation in the alchemy furnace.

After finishing the alchemy furnace, Yi Chen began to refine the immortal pill.

The alchemy technique was cast, and the red flame enveloped the entire alchemy furnace.

All kinds of low-grade immortal materials were put into the alchemy furnace.

Then, they continued to melt in the red flame.

Various negative characteristics were extracted and stripped out, and the materials gradually merged and improved.

With only three materials, the characteristics could not be merged and the internal energy was disordered.

Yi Chen immediately stopped refining the pill and re-deduce the pill formula according to the fusion process.

Then continue to refine according to the newly deduced pill formula.

This cycle repeats itself.

After five or six days, he finally successfully refined a furnace of low-grade immortal pills.

Yi Chen named it Ji Yu Dan.

This Ji Yu Dan is a defensive type of immortal pill he refined based on the physique of the demon race.

After taking it, it can greatly improve the physical defense ability of the demon race, and can make the defense of the demon race reach an extremely terrifying level in a short period of time.

This Ji Yu Dan is the biggest reliance of the swamp crocodile to break through the heavenly tribulation.

After successfully deducing the formula of Ji Yu Dan and refining a furnace, Yi Chen did not stop, but took out the corresponding materials and continued to refine Ji Yu Dan.

Not only the swamp crocodile needs to pass the tribulation, but also the full-level fierce beasts.

A low-grade immortal pill-level Ji Yu Dan is enough for a full-level fierce beast to pass the tribulation easily.

In the Great Yan Empire, where a group of powerful monsters are urgently needed to be cultivated at this stage, Yi Chen naturally does not mind wasting some time to refine a batch of Ji Yu Dan.

As for the future, if the monsters want to obtain Ji Yu Dan to pass the tribulation, they have to make contributions.

This Ji Yu Dan is also one of Yi Chen's means to control the number of monsters in the future. In terms of the formula, he will only teach it to a small number of top alchemists.

It took more than ten days to refine more than 10,000 Ji Yu Dan, and Yi Chen stopped.

It's not that the number of these Ji Yu Dan is enough, but there is no material to refine Ji Yu Dan.

The next step is to create a powerful defensive fairy weapon for the swamp crocodile.

Ji Yu Dan can ensure that any monster can pass the tribulation successfully.

But the swamp crocodile was the first demon to pass the tribulation. Judging from the fluctuation of the power of the law, although it was far less than the intensity of the tribulation that Yi Chen faced, it was far more than the intensity of the tribulation of ordinary demons.

Even though the Ji Yu Dan was a low-grade immortal pill, and it was made by Yi Chen himself, it was still a little bit worse.

Coupled with an immortal weapon with powerful defense and spiritual materials obtained from the Shadow Clan that can quickly restore energy, it is almost enough.

Taking out the materials for refining the defensive fairy weapon, Yi Chen immediately started refining it.

The human race and the demon race have different physiques, different energies, and even different methods of movement. When refining immortal weapons, they naturally have to be tailored according to the characteristics of the demon race.

However, these are not difficult in Yi Chen's eyes.

As long as there are enough materials and he is just refining a low-grade fairy weapon, even if it is tailor-made according to the characteristics of the demon clan, there will be no difficulty for him.

In less than a day, he refined a piece of armor that was as black as ink and had an amplifying array and a defensive array inside.

It took less than half a month to get it all done.

With a thought, Yi Chen left the flying magic weapon and came to the swamp crocodile.

With a wave of his hand, the armor flew towards the swamp crocodile.

"This celestial weapon is custom-made by me based on your demonic power. Give it a try by dripping your blood to identify the master."

Yi Chen gestured.

"Thank you Master for the gift!"

The swamp crocodile is overjoyed.

He hurriedly bit the tip of his tongue and dropped a drop of blood that was fused with his own perception onto the armor.

The next second, he immediately sensed a vague connection between the armor and himself.

Moreover, the armor seemed to be alive, actively flying in front of him, constantly expanding and changing according to his size.

Covered his body.

Let his whole body be shrouded in armor.

A special message also poured into his mind from the armor.

Let him instantly understand the purpose and method of this armor.

The terrifying defensive power made his face look ecstatic.

Being greedy for life and afraid of death, what he wants most is this kind of defensive magic weapon.

For this reason, he originally spent a lot of materials and favors, and asked top geniuses who were proficient in weapon refining to help him create a defensive magic weapon.

However, the top genius cannot refine a magic weapon suitable for him based on the characteristics of the demon clan. The only effect of that defensive magic weapon on him is that the material itself has a certain defensive power.

That little bit of defensive power is simply negligible compared to the immortal weapon Yi Chen refined.
