"Number One?" Ling Feng asked in surprise, "Who is Number One?"

"I don't know!" Unexpectedly, the young man with purple hair said, "In the laboratory, apart from a few people, no one knows who Number One is, but what I do know is that Number One's strength is definitely greater than mine!"

Ling Feng frowned, "Is Number One also on the island?"

"Definitely here!" The young man with purple hair said, "I have a feeling Number One also wants to seize the experimental potion. He definitely won't miss this opportunity!"

The young man with purple hair looked at Ling Feng and said, "Keep me alive, I can help you deal with Number One, I promise to be loyal and will never betray you!"

Ling Feng chuckled softly, "Maybe you're right, but... I still don't trust you, so you should just die! Only a dead person can set my mind at ease!"

As he spoke, Ling Feng exerted force with his right hand, and the purple-haired young man's struggles gradually weakened. With a slap, he fell to the ground, and soon, his body also gradually returned to its original state!

"Hmm?" At this moment, Ling Feng noticed something seemed to be wriggling on the purple-haired young man's forehead, and soon, a black Ghost-faced Devil Bug emerged from his forehead, baring its teeth as it charged at Ling Feng!

Without the protection of a host, the Ghost-faced Devil Bug hasn't fully matured yet and is quite vulnerable, so it must find a new host immediately, and naturally, Ling Feng became its primary target!

"Freeze!" Ling Feng waved his hand, and a blast of icy air immediately froze the Ghost-faced Devil Bug that was halfway through its charge.

Ling Feng picked up the frozen Ghost-faced Devil Bug. Looking at its clawing shape, he couldn't help but laugh, "To think it would come after me, I must have been underestimated by a bug!"

After securing the Ghost-faced Devil Bug, Ling Feng returned to the Potion Room and successfully found the safe where the potions were stored.

Looking at the familiar-looking safe, Ling Feng raised an eyebrow, "I wonder if Mad Doctor has changed the safe's code!"

Saying this, Ling Feng entered the safe's code. With a click, the safe surprisingly opened, which made Ling Feng sweat a little. Did Mad Doctor never change his code?

The code Ling Feng entered was given to him by Catherine, who said that all of Mad Doctor's safes use the same code, and naturally, as Mad Doctor's assistant, Catherine also knew it.

But what Ling Feng didn't expect was that even after arriving in the alternate dimension, Mad Doctor hadn't changed his password!

Ling Feng looked at the azure blue potion inside. As soon as he reached out to grab it, he felt a prickling sensation on his back, and he quickly turned around, "Who?"

"I didn't expect Number Two wasn't a match for you. Your strength has really opened my eyes!" A humanoid shadow with a ghostly face appeared in front of Ling Feng.

Ling Feng felt a powerful pressure emanating from this shadow!

"Are you Number One?" Ling Feng asked in a deep voice.

The shadow looked at Ling Feng, "That's right, I am Number One. You must be from the Royal Court, right? Hand over the potion, and I can spare your life!"

"Is this potion very important to you?" Ling Feng asked, shaking the potion in his hand.

"Of course, I know you're quite powerful, but you're not my opponent!" The shadow said plainly, "Give me the potion, and I promise your safety, I can even escort you out!"

Ling Feng smiled slightly, "You talk big. You haven't even reached Azure Sky Realm, what gives you the right to make such promises? Besides, I also have someone who needs this potion, so it's impossible for you to take it from me!"

"If the person you're talking about is Number Three, then I don't think you need to worry about him!" Number One said lightly, "Because Number Three is already in my hands. If you don't hand over the potion, I can kill Number Three now!"

Ling Feng's eyes narrowed, "What? Ling Yun is in your hands? You're in the basement of the laboratory?"

"It seems you're a bit slow on the uptake!" Number One said lightly, "I'm waiting for you in the basement, I hope you think about my words before coming in!"

Saying this, Number One's figure slowly disappeared from Ling Feng's sight!

Ling Feng frowned; he didn't expect that Number One was actually hiding in the basement of the laboratory. Now, not only was Ling Yun captured, but Carly had definitely fallen into Number One's hands too!

And his mission was to protect Carly; now the mission is likely to fail!

Ling Feng sighed and then found the entrance to the laboratory's basement, slowly sneaking down.

Along the way, Ling Feng saw many corpses, both of laboratory personnel and of the experimental subjects. The surrounding air was filled with a distressing odor.

When Ling Feng reached the room at the bottom floor, suddenly, the door to the room opened, and a beam of light shone from inside to the outside.

"Since you're here, come in!" Number One's voice rang in Ling Feng's ears.

Ling Feng pushed the door open and entered, "I'm here, where are my people?"

"What if I told you I killed them?" Number One looked at Ling Feng with a mocking tone.

Ling Feng said coldly, "Then you can forget about the potion, and besides... I will also kill you!"

"Truly a terrifying sight!" Number One smiled slightly, "Don't worry, they are fine, if you don't believe me, have a look!"

Saying this, Number One pressed a button on the console, and a screen appeared on the display showing Ling Yun and Carly.

The two of them had fainted on the ground but were temporarily not in any life-threatening danger, which allowed Ling Feng to secretly breathe a sigh of relief!

"Hand over the potion, or else, I can kill these two with a wave of my hand!" Number One said flatly.

Instead of handing over the potion, Ling Feng asked, "Number One, what's your goal? Is it really this potion?"

"What do you mean?" Number One asked coldly.

Ling Feng, as if talking to himself, said, "I thought about many things along the way, tried to piece the story together from beginning to end, and when I reviewed the whole affair, I found something very puzzling, which I think maybe you can help me understand!"

Number One didn't speak, just stared at Ling Feng.

Ling Feng continued, "The purpose of the laboratory is to develop a potion to help the experimental subjects control the Ghost-faced Devil Bug, aiming for mass production of Azure Sky Realm masters!"

"So what?" Number One said nonchalantly.

"But, precisely because of this, the Ghost-faced Devil Bugs inside the experimental subjects sensed danger and naturally would not stand idly by, so, under their influence, the experimental subjects rioted! This is what led to the destruction of the entire laboratory!"
