Mu Pu really lived up to Su Huan's trust.

When Su Huan came to the door the next day, he handed over a hideous dragon head as big as a house to Su Huan.

and took ten energy gems from Su Huan.

Su Huan took this hideous head and returned directly to Longfu, Su Huan's laboratory.

In the depths of Su Huan's laboratory, in a laboratory exclusive to Su Huan, Su Huan began to configure the dark potion.

The first step in configuring the potion was naturally to deal with this hard-won Dark Head of the Nine-Headed Dragon Lizard.

When the hideous head covered with pitch-black shiny dragon scales was placed behind the test table.

Su Huan first used special equipment to pry off all the dragon scales piece by piece.

And piled up in a pre-prepared alley on the side.

These dragon scales are excellent materials for making strange things.

It can even be used as a raw material for many secret medicines, and even a transformation material for dangerous creatures, which naturally cannot be wasted.

This faucet is complete.

After removing the dragon scales, Su Huan immediately took down the two dragon eyes that were as big as a millstone.

And then there's the dragon's horn.

In the end, Su Huan turned on the ultra-high frequency energy wave blade switch on the experimental table, and cut the hard skull of the dark head little by little.

Carefully removed the pitch-black and wriggling brain.

Dark Brain!

It's finally here!

Su Huan had already prepared a large vat of solution in advance.

Let the Dark Brain fill it in and soak it in the solution.

Then, the fixed space shook off for a while.

The various materials of the Darkest Potion were held up by the spiritual power and fluttered down on the experimental table.

A piece of material is processed in Su Huan's hands like a butterfly wearing flowers.

But that's it, Su Huan is not fast enough, and secretly said that if the Saru monster did not stay in the new Black Light Fort but was by his side, the configuration process would probably be easier and faster.

After the material has finished processing.

The next thing is the potion configuration process that Su Huan is familiar with.

About an hour or so later.

A bottle of potion that was as black as ink and was still bubbling with colorful bubbles appeared in Su Huan's hand.

In fact, it is not very appropriate to say that it is a bottle.

The container containing the potion was the size of an adult's waist and more than a meter tall.

It is not an exaggeration to say that it is a cylinder.

Su Huan had already concentrated the amount of potion according to the limit, and there was still such a large vat left.

In desperation, Su Huan could only summon the Extremely Dark Light Ji and let him drink a large vat of dark potions.

Extremely Dark Light Ji's current body size is no longer as petite as when Su Huan first met her.

Standing in front of Su Huan, she was like a giantess.

The height at the shoulder is more than three meters.

The potion that was like a jar in Su Huan's hand seemed to have recovered the bottle in the hands of the Extremely Dark Light Ji.

Extremely Dark Light Ji picked up the "bottle" of potion and gulped it all into her mouth, leaving not a drop left.

When the last drop of the potion also slid down the red lips of the extremely dark light and fell into her mouth.

The extremely dark light Ji was already filled with a thick black mist that could not be completely contained.

Su Huan hurriedly put all the instruments in the laboratory, including the laboratory table, into a fixed space.

Then the reinforcement door of the laboratory was opened, and the sealing of the laboratory was strengthened again.

Then, he dodged and hid in the researcher's safe haven in the corner of the laboratory, quietly watching the changes in the extremely dark light in the laboratory.

But before he could take a few looks, the laboratory was completely shrouded in darkness.

And the extremely dark light Ji who was in the center of the darkness also completely disappeared from Su Huan's field of vision.

This layer of darkness seems to have a special power.

Even Su Huan's near-envoy-level psychic perception could not penetrate the darkness and perceive any of the circumstances.

Another long wait.

However, this time the wait was not as torturous for Su Huan as the transformation and evolution of the pet.

This is just a growth and transformation of Extremely Dark Light Ji.

And the Extremely Dark Light Ji has also been accumulating for a long time in this growth stage.

With the help of the Darkest Elixir, there is almost no chance of failure in growth and transformation.

Of course, without the accumulation of Extremely Dark Light Ji at this stage of growth, even if you need the help of the Dark Elixir, or even the help of the more effective and higher-level potions and secret medicines, the probability of success is still very small.

In the final analysis, even if you take drugs, you must have the corresponding background and accumulation.

Secret potions and potions can only play a role in promoting the growth and transformation of pets at most.

But it can't make growth and transformation happen overnight.

On the other side of Su Huan's spiritual fetters, the soul belonging to the Extremely Dark Light Ji is constantly increasing.

The increased speed even Su Huan couldn't help but be shocked.

If it weren't clear that the Extremely Dark Light Ji was just a growth and transformation in the growth stage, Su Huan even suspected that the Extremely Dark Light Ji was transforming and evolving into a disaster species.

"Darkest Light Ji, it's really exciting!" Su Huan couldn't help but show hope.

This growth and transformation of the Extremely Dark Light Ji is not just an increase in strength.

It is also where Su Huan's confidence lies in resisting the Mother of Evil Church next.

Not long after the transformation and evolution, the Extremely Dark Light Ji had successfully attenuated the strength of the Thunder Crown Thunder Eagle King to the limit of the calamity species.

Once it grows to the Darkest Light Ji, it is not counted as a new innate power skill, but only an increase in the original ability.

It is enough to ensure that the Darkest Light Ji can weaken the strength of the disaster species that she has grown and transformed to a range that she can deal with.

This will be crucial in the coming crisis.

Su Huan waited silently in the cubicle of the laboratory.

Before he started the experiment, he had told his subordinates to conduct an important experiment that would last for many days.

Don't disturb him.

Therefore, there are no external factors that interfere with the growth and transformation in the laboratory these days.

Even if Su Huan kidnapped Chage in Judgment City, the matter is still fermenting.

But it still didn't affect Su Huan, who was far away in Longfu.

It is impossible for anyone to suspect Su Huan.

First of all, the timing is not right.

Longfu is more than 100,000 miles away from the City of Judgment.

Even a catastrophe is not something that can be resisted in a short period of time.

Of course, if you know the specific movement speed of Su Huan's Soul Miao Tree Dragon, you may have doubts.

But how fast the Energy Devouring Miaoshu Dragon moved, only Su Huan knew alone.

Time came half a month later.

It has been more than half a month since Su Huan left the New Black Light Castle.

Su Huan also gradually became anxious.

Despite the intelligence agencies of the Ringing Fortress City, the Church of the Mother of Evil was acting two months later.

But whoever knows for sure is that punctual.

Finally, this day.

The darkness that shrouded the extremely dark light finally cracked a crack.

Let no light shine at all into a ray of light.

Then, as if in the center of the darkness, a whirlpool rolled up.

The mist-thick darkness swirled suddenly.

As it swirls, the dark mist forms a small vortex.

The dark mist grew thinner and thinner, absorbing it all as if it had been swallowed by the dark source in the center of the whirlpool.

A slender arm stretched out of the darkness.
