But the steel fork couldn't break the specially designed cage.

The steel fork bounced off the tempered glass, almost hitting the Speed Demon.

The Speed Demon was furious enough to jump up.

As the gravity in the room began to increase, the Speed Demon felt its body growing heavier and heavier.

It gritted its teeth, determined to withstand it, but in the end, it couldn't endure and crashed onto the ground from mid-air, its head bleeding.

"Take advantage of this moment, capture the Speed Demon, and test its relevant data."

Ye Bai instructed the researcher beside him.

The Speed Demon's enormous bat wings were tightly pressed against the ground, revealing a grimacing expression.

The demon had steel bones all over, even if the Speed Demon fell from such a height.

The researcher hastily operated the robotic arm, grabbed the Speed Demon, and injected a tranquilizer.

With the tranquilizer injected, the previously agitated Speed Demon calmed down.

Its consciousness was clear, but it couldn't move.

There was also a large iron chain restricting the Speed Demon's movements.

The researchers looked at the Speed Demon with fervent eyes, it was like a walking achievement.

The fast-running Speed Demon, they had no other way, now the Speed Demon was all tied up on the operating table.

If this can't be handled, don't bother showing yourself.

"Begin drug testing."

"Initiate current testing."

The researchers eagerly began various tests, tears of regret silently fell from the Speed Demon, it might be the worst-off Speed Demon.

"I'll leave the Speed Demon to you all, I just need a result."

"I'll go see how to handle the Big Mouth Demon."

Ye Bai left with hands in pockets, taking the demon teddy bear with him.

The Big Mouth Demon stood a full two meters high, its appearance resembling a large sea urchin.

It had two sturdy arms and no legs, meaning it could move in two ways.

One: using its arms instead of legs to walk, and the other: curling its body up and rolling to move.

It had a large mouth filled with sharp teeth.

Seeing this demon, Ye Bai sighed, if we could remove the spikes, add two naive big eyes, hey, it would be like a little Geodude.

"What's the current research progress?"

Ye Bai asked the researcher.

"So far we've tested many methods, but none can open the Big Mouth Demon's hard shell."

"Whether using gravity, fire burn, or current, nothing seems to impact the Big Mouth Demon at all."

The team reported to Ye Bai.

"Do you see that mouth?"

"I think if we can make it open its mouth, everything might be easily solved."

The mouth was the lifeline of the Big Mouth Demon, apart from feeding, it almost never opened its mouth.

Under Ye Bai's direction, researchers placed a rabbit into the room.

At this moment, the Big Mouth Demon made a move, suddenly baring its mouth filled with sharp teeth.

A large tongue protruded from its mouth.

Ye Bai actually saw an eye inside the Big Mouth Demon's mouth.

[Name: Big Mouth Demon]

[Gender: Male]

[Attribute: Gold/Dark]

[Trait: Unbreakable, as long as it closes its mouth, many things in the world can't harm it.]

[Level: Tier Five Peak]

[Mastered Skills: Steel Enhancement (Mastery): The unbreakable body becomes even harder, utilizing steel spikes on its body to damage opponents.

Vibration Wave (Skilled): Uses powerful hands to slam the ground, creating intense earthquake waves, opponents hit will fall into a dizzy state.

Dagger Fang Spray (Mastery): Sprays sharp teeth like daggers from its mouth to attack its opponent, the moment the teeth hit, the opponent's soul falls into intense pain.

Steel Bones (Skilled): Its hands are its strongest weapon, capable of punching through hard stone slabs with one blow.

Super Heavy Punch (Skilled): Uses fists covered with spikes to strike opponents, accompanied by gravity effects.

Sea Urchin Defense (Beginner): When facing lethal attacks, spikes on its body inflate like a sea urchin.]

[Evolutionary Path 1: None yet.]

[Evaluation: A twisted creation, a plaything made by the Demon God of the Abyss, its weakness lies in the eye inside its mouth.]

The Big Mouth Demon's feeding time was brief, yet Ye Bai managed to capture the eye inside its mouth using room cameras.

"This eye could very likely be the lifeline of the Big Mouth Demon, I propose figuring out a way to make it swallow a prey injected with poison, to see if it can destroy the Big Mouth Demon."

The researchers immediately followed Ye Bai's instructions, attaching a C4 bomb to a small white rabbit.

Once the Big Mouth Demon devoured the rabbit, the C4 bomb exploded at once.

At that moment, the Big Mouth Demon's body suddenly began to inflate like a balloon.

Its flesh burst open with a crash, spreading black demon blood throughout the space.

????

Wow, how did the Big Mouth Demon get taken down so easily?

This isn't scientific.

The researchers were slightly speechless.

"Attention everyone."

"Demons are not invincible, they have various weaknesses; even the strongest demons have weaknesses."

"Now, there's the Fire Demon, Ice Demon, and Poppy Flower Demon left, please continue tackling them."

"I have other experiments to conduct, so I'll temporarily excuse myself."
