“Bang!”

“Crash——”

Something was broken.

Then, the yellow-green liquid began to flow out from the ground between several experimental petri dishes.

Cheng Shi's nerves tensed up and he immediately grabbed the scalpel in his hand, hunched over, and was ready to strike.

Magician Li produced a glowing poker out of thin air in an instant and threw it casually. A sparkling butterfly emerged from the poker and flew towards the place where the sound came from with its wings flashing.

Cheng Shi had seen the Sound-Seeking Butterfly in his monthly ladder settlement. It was a B-level creature from the Island of Hope. When it flapped its wings, the bright crystal powder it spread would reproduce the scene it saw in mid-air.

Because this butterfly likes to fly following sounds, it is often used for reconnaissance and searching for enemies in suppressive battlefields.

Gao San also reacted immediately. He did not take a defensive stance, but took advantage of the moment when Cheng Shi and Li Yi stopped and ran towards the wooden door.

At this moment, when Cheng Shi was frowning and thinking whether he should use [Thunder Judgment] on Gao San first to solve a variable, a heavy cough came from the side.

Cheng Shi's heart tightened and he turned around immediately.

Then he and Li Yi saw the pool of yellow-green liquid not far away, and then an old man with silver hair slowly walked out.

There is no need for the Sound-Seeking Butterfly to search, the person who made the noise has already stepped forward!

Cheng Shi's pupils shrank as he recognized his identity.

Serius, a great scholar from the Life Extension Department of the Tower of Matter, is the real boss of this underground laboratory.

"Ahem... Sorry, I'm old and my hands and feet are a bit clumsy. I broke the petri dish, but it's okay. These liquids don't contain volatile toxins. There's no need to be nervous."

He walked towards Cheng Shi and Li Yi with a smile, but after he had taken a few steps, Li Yi stopped him with an extremely serious expression.

"Don't come over here, or I'll do it."

As he spoke, Li Yi punched the experimental device beside him.

However, the experimental device hidden behind the black cloth only made a muffled "bang" sound and then there was no response.

"I'm curious, Mr. Serius, how did you break such a strong experimental glass?"

Cheng Shi raised his eyebrows and quietly raised the hand wearing the ring.

"I was just checking the status of the experimental materials, and I accidentally pressed the wrong button..."

"That's enough. There's no need to use such lame excuses. I just carefully observed these culture dishes. There is no external interface or control button above or below the glass. What on earth are you...

Who is it?

What do you want to do now? "

“Haha, young man, you know me, you know my name, and you know that I’m a scholar here, so why are you asking such meaningless nonsense?

What's more, this is my laboratory. Even if I need to ask, I should be the one asking you.

You shouldn't be here, especially with the 'gladiator mask' I made for you."

What is fighting?

Cheng Shi touched his prisoner helmet in astonishment and laughed inwardly.

How come everything can be called a mask now? If that’s the case, wouldn’t I have surpassed the two-faced person and become a three-faced person?

It’s not impossible.

Ha, that's great, a liar should have enough disguise.

...

Meanwhile, on the other side.

The moment Gao San rushed into the room, he immediately turned around and closed the door, and stood close to the wall to prevent Cheng Shi from using the terrifying thunder behind him again.

But he waited for a long time but there was no sound of pursuit, so he breathed a sigh of relief and began to look around the extremely dark room nervously.

However, just as he was about to take a groping step forward, the light came on.

A beam of warm light shone on the laboratory table not far away. An old man with silver hair opposite the table slowly raised his head, looked at the uninvited guest, and smiled kindly.

"It seems that there is a guest in the laboratory. Well, a guest who shouldn't be there."

Gao San was shocked when he saw the old man for the first time, because he had seen this old man before, or rather, he had seen this scholar before.

“It’s you!

Serius! "
