My health recovery is incredibly fast.

The penumbra of the Cube Shadow Fiend corresponds to the Blood Fiend's Blood Fiend husk.

Its true form corresponds to the Blood Demon's Blood Essence Stone.

Unlike the Blood Demon's body, which is highly poisonous and extremely difficult to cut, the penumbra that envelops the Shadow Demon's true form is very fragile and will dissolve if exposed to strong light.

However, the penumbra will recover as soon as the light dims, which is much better than the Blood Demon's body.

Shadow Fiend has so many flaws, and they are so obvious.

After the team captured it, they were able to remove its body with almost no effort, allowing them to directly study the secrets of the umbra. It was practically a freebie, and the research progress would be extremely fast.

Xia Zuo finished reading the file, checked the time, and then quickly walked to the door to go to the underground laboratory to get the sample.

...

Six underground floors, Laboratory No. 15.

Xia Zuo put on sunglasses, unlocked the door, and went inside.

This place is simply an ocean of light.

The walls, ceiling, floor, and under the tables of the entire room are covered with glass-encased light-emitting tubes, and the light evenly fills every corner of the room without any shadows.

The cultivation tank that sealed the Shadow Demon underwent special modifications.

The tank is still made of one-way transparent glass.

But a circular pool was added around it.

Ribbons and sequins that refract light are placed in the pool.

The pool water is kept flowing, keeping the ribbons and sequins constantly tumbling and flowing. When the refracted light shines on the cube-shaped shadow demon, it will tear off a small clump of the shadow's fragments.

The debris sank to the bottom of the water and was picked up by a tiny robotic arm and sent to a closed operating platform next to it.

Xia Zuo stayed by the control panel, watching for a few minutes as the process of sealing the umbra fragments was carried out, before leaving with a briefcase.

When I returned to the alchemy room, it was exactly 9:48 a.m.

Xia Zuo sat down at the control panel and switched to the view of [Minion No. 1].

A female train attendant in uniform entered the carriage and reminded passengers that they would be arriving in Polis in about 15 minutes.

During this short period of time, Xia Zuo put the fragments of the umbra into the enclosed operating table to pre-process the poison that needed to be identified.

Fifteen minutes later, the train pulled into the station.

Xia Zuo temporarily put aside his work and focused on controlling Servant No. 1.

As a member of the Silvermoon Federation, Polis City is a city created by the same alchemy school. The layout of the city is similar to that of Poseidon, with mostly high-rise buildings in the city center and low-rise houses near the suburbs.

Xia Zuo activated the [Blood Curse] to check the location of the three Transformers.

The second potential benefit of the Blood Element Servant has emerged.

When checking the target's location, Xia Zuo can switch the observation point from himself to the Blood Element Servant and find the target's location from the Blood Element Servant's perspective.

Xia Zuo searched carefully and discovered that the Transformer was actually underground?!

"Huh?" Xia Zuo, sitting in front of the control panel, scratched his head in confusion.

Does Polis have a subway?

Definitely not.

Could there be some kind of hidden underground city?

The three shapeshifters were located quite deep, about 15 meters underground.

Following the guidance of the [Blood Curse], Xia Zuo controlled his No. 1 servant to pass through the railway station wall and onto the street, proceeding along the street.

A 20-story building appeared near the central urban area.

In terms of appearance, it is somewhat similar to the Bosing Tower, both being significantly taller than other buildings, with a huge white crystal suspended in the air on the first floor of the lobby, and similar features...

basement…

Xia Zuo's expression changed, looking somewhat surprised and embarrassed.

Could it be that those three shapeshifters were already captured by the Polis City task force and imprisoned in the underground laboratory?!

So he might have stolen some experience points from his allies?

This is so embarrassing.

No, no, no...

Xia Zuo slapped his forehead and thought of another possibility.

Could it be that the action team in Polis City received intelligence from Rexol, found the remains of these three shapeshifters in the East District, and then took them back to the lab for research?

Um..

The possibility is great.

He hadn't paid attention to the location of the Transformers for the past few days, and since Poseidon and Polis City were dozens of kilometers apart, whether it was in the central or eastern part of Polis City, it was all in the north to him, so the difference was minimal.

The key is.

Transformers cannot self-destruct when they are confined in culture tanks.

But the Blood Demon's command at the time was "self-destruct".

Therefore, it can be inferred that the waste in the underground laboratory was brought back after the converter died.

Xia Zuo understood the cause and effect, and couldn't help but breathe a sigh of relief.

He didn't have the guts to control Servant Number One to fly into the building's lobby; those enormous white crystals floating on the ceiling looked menacing.

He could only walk around the building once, trying to guess the exact location of the Transformers based on the layout of the Pershing Building.

That's right, it's definitely in the laboratory on the fourth basement level.

Xia Zuorang's Servant No. 1 flew back to the front of the building and looked at the name of the building.

The Porras Building

He scanned the surrounding streets through the perspective of Servant Number 1, pondered for a few seconds, and decided to find a place to hide, thinking that he might need this servant in the future.

Servant Number 1 flew to the shop across the street and squeezed into a small gap in the shop's signboard to shelter from the wind and rain.

Then, Xia Zuo focused his attention on the work at hand.

When he put the Shadow Shards into the control panel, he deliberately left a small amount out, just to test the poison's effects with [Flesh Control] and see if the Shadow Fiend had anything like a Blood Mark.

Xia Zuo checked the blood pack and the life alchemy stone, and after confirming that everything was ready, he used his palm to hold the pinch of the original shadow fragment.

His skin turned black in an instant, with purple lines running across its surface, blood vessels bulging around his eyes, and his face covered in swollen lines.

One second, two seconds, three seconds passed.

"Huff...huff..." Xia Zuo opened his eyes and gasped for breath, fragments of his original image appearing in his palm.

He immediately put the fragments into a test tube on the workbench and then noticed that his skin had turned dark. It took about 10 minutes for his skin to gradually lighten and return to its normal color.

"Holy crap... the poison effects of the Shadow Shards are absolutely bizarre..."

Xia Zuo patted his chest in lingering fear, mentally reviewing the list of poisons he had previously obtained.

...

[Severe self-doubt]: Every second, you will experience an uncontrollable feeling of doubt about the operation you are about to perform, lasting for 5 seconds.

(The rest omitted)

...

As is well known, Shadow Fiend's growth is very difficult.

Xia Zuo speculated.

Shadow Fiend often struggles when faced with a shadow whose size is unpredictable. If this continues, he may either die by accident or develop a serious mental illness.

This may be the origin of the toxic effect of "severe self-doubt".

However, we cannot be completely certain.

Because I have never seen the toxic effects that evolved from mental illness.

However, the existence of this toxic effect cannot be denied. It may be a very complex toxic effect that requires multiple toxins to produce.

Otherwise, it wouldn't have such a terrifying effect!

When Xia Zuo tests poisons, he always prioritizes stability. He will immediately remove the [Flesh and Blood Control] as soon as the poison takes effect.

Just now, after being exposed to the poison of "severe self-doubt," his mind was filled with:

Should we dispel the [Flesh and Blood Control]?

Why don't I release [Flesh and Blood Control]?

"Why haven't I been able to break free from [Flesh and Blood Control] yet?"

Questions like this.

If it weren't for the fact that the character template isn't affected by poison effects, he probably would have been poisoned to death by other poisons.

Unfortunately, this poison test only yielded toxic effects.

Shadow Fiend doesn't have anything similar to the Blood Mark.

Xia Zuo took a sip of tea to calm himself down and began working on creating an antidote to counteract the effects of the primordial poison.

Chapter 73 Micro Plasticity Field Devices

noon.

After finishing his lunch, Xia Zuo chatted with Anruer for a while using the secret communication ring before returning to the alchemy room to sit down.

Tomorrow is Thursday, and I need to spend the entire day and night in the laboratory on the 7th basement level where high-level blood demons are imprisoned.

I need to finish my tasks today.

Xia Zuo first checked on the condition of Servant No. 1, and then got back to work.
