Mist

"Suturing? Aren't you specializing in Plague Studies?"

"They all fall under the category of mysticism. Before the Talent Tree is established, try to learn about all aspects and see what suits you best."

After saying that, Han Dong deliberately fiddled with the needle and thread between his eyebrows, pretending to thread the needle.

Han Dong had naturally learned some basic knowledge of sutures, and he did this only to disguise the "Lesser Demon Eye" as a skill of sutures.

The moment the Lesser Demon Eye opened.

Han Dong tried his best to suppress the 'pollution release' back into his eyes, but a faint smell of pollution still wafted out from around his eye sockets.

However, because the Maldini mansion itself was filled with a strange atmosphere, Cas and the others did not notice.

Only Sylest, walking at the back, cast a questioning glance and muttered softly, "This kid... he's learned a new trick again."

Han Dong also felt Sylest's gaze, and felt a wave of helplessness, thinking to himself:

"Hmph... It seems the Lesser Demon Eye still needs further 'polishing'. Even Though my full suppression, a small amount of polluting aura still escapes. Cas has no doubts because of the absolute trust between us."

It now seems impossible to fool the Formal Knight.

Before the [Knight Training Camp] begins, the disguise must be so perfect that it's indistinguishable from the stitched-on eyes.

As the Lesser Demon Eye is activated.

Han Dong finally saw some unusual 'things' inside the mansion.

A thin layer of mist appeared inside the mansion.

It covers doors, lighting fixtures, copper metal fittings, and corner areas.

As far as Han Dong was concerned, he did not sense any danger from the fog.

As the team stepped onto the Third Floor, the footsteps that had been lingering in the master bedroom disappeared.

The master bedroom door was tightly closed, showing no signs of having been opened.

"Didn't leave the room? Was he just sleepwalking in the room... something's not right."

This is the House of Cas. Breaking into the master bedroom at night is very impolite and might even anger Viscount Alex... However, tonight is also a great opportunity to find out the truth.

Cas had already come up with an excuse and arrived at the master bedroom door.

"Wait for me a moment, I'll go knock on the door."

thump thump thump...

Despite repeated knocking, there was no response from inside the master bedroom.

Realizing something was wrong, Cas slammed his palm into the lock, shattering the internal mechanical parts.

The loud noise of the door being broken did not disturb the parents in the master bedroom.

When Cas pushed open the door and entered, Han Dong and the others immediately followed.

The kerosene lamp was turned on, and the warm flame immediately illuminated the master bedroom completely.

Only Cas's mother was lying in bed; Viscount Alex was nowhere to be seen.

Sylest immediately went over to examine Cas's mother. "Her breathing is normal, but she's been affected and is in a deep sleep... This state should last until dawn."

Upon hearing that his mother was safe and sound, Cas breathed a sigh of relief.

The next step is to solve the mystery of the 'escape room'.

The windows and bedroom doors are locked from the inside.

The fireplace opening is too narrow for a person to pass through... How did Viscount Alex leave the room?

"The fog has thickened... The fog concentration in the master bedroom is about three times that outside, but this fog is not dangerous for the time being, and we don't know what its purpose is."

In addition, thanks to the special vision of the [Lesser Demon Eye], Han Dong could also see the footprints left on the wooden floor.

The footsteps were the same as those heard before.

Viscount Alex once walked around the room.

A neat and overlapping circle of footprints was left on the ground, a perfect circle, without a single step off.

Just as Cas and his men were searching the master bedroom, trying to find the secret compartment.

Han Dong recalled the footsteps he had heard earlier.

Following the same frequency and comparing it to the footprints, start walking in circles.

Exactly ten laps!

The wall directly opposite the bedroom bed began to slowly rotate.

The mechanical movement is smooth, without any friction noise throughout.

A Secret Corridor connecting the east and west buildings was revealed.

Viscount Alex could use this secret passage to go directly from the master bedroom to the Third Floor of the west wing... which was also an important area for creating works.

"This..."

Cas clearly knew nothing about this secret passage.

Moreover, he rarely visited his father's private creative area.

That is, when the secret passage is revealed.

From the dark and deep secret passage, Han Dong saw white mist constantly surging out, and even glimpsed some pale tentacles that were both real and ethereal, appearing and disappearing in the mist.

Even Cas and the others could see a small amount of white mist spreading through the passage with the naked eye.

Buzz!

The cross relic in Sylest's hand is activated.

Centered on the cross, a holy light armor materialized, covering Sylest's entire body, and she also put on "goggles".

Due to the influence of an invisible fog.

The communication array of the Clockwork Device was affected, and it was unable to transmit information outwards.

Sylest made a decision. "Nicholas and I will investigate further, and you two will report any unusual information to the Knight Order... The urgency level is estimated to be 'Level II', and possibly even higher."

"What?!"

Although Cas noticed something was wrong, he didn't expect the situation to be so serious.

"Go directly to the Holy Knight Order and give them my name! It would be best to have at least three Formal Knight proficient in Holy Light assist you."

"... Okay! I'll go right away."

Han Dong instructed, "Put on your goggles before you go... the fog has already spread throughout the mansion area."

Standing at the window, Han Dong observed that the entire Maldini estate, including the front garden area, was shrouded in mist.

Cas and Sophia may be ambushed as they leave the mansion.

"I'm entrusting my father's matter to you... If you can suppress the situation, try your best not to hurt him."

Sylest said solemnly, "Viscount Alex is a writer of great importance to the Holy City, and I will do everything in my power to ensure his safety."

"Thanks!"

Cas received the blessing of the holy light, put on his goggles, and left the mansion with Sophia in his hand.

Sylest stared at the secret passage, gritting her teeth slightly as she said, "I didn't expect even the nobles on the Third Floor to be affected... However, it could also be due to the inherent risks of being a 'writer'."

Han Dong asked, "Should we continue deeper, or wait for the Knight Order to arrive?"

Sylest continuously applied buffs to herself and Han Dong, pointing towards the entrance of the secret passage.

"Let's go deeper... Anyway, you're not afraid of 'pollution,' are you?"

The target has just started his activity. If we can seize the opportunity to control Viscount Alex, we might be able to resolve this matter directly.

Then, I will find the root of the problem from him and kill the mastermind behind it all.

Furthermore, opening the secret passage might have already alerted the enemy.

If we stay here, things might get worse... Viscount Alex might also be in danger.
