Sanity value.

In the settings of various Cthulhu games in the past, it is also called SAN value.

When Lu Ze was creating the illusion, he combined this system with the Fear Soul Binding Array.

Sanity will decrease in the absence of light or in the presence of external factors such as evil spirits.

This is not just a reduction in numbers.

At the same time, it will gradually dissipate the effect of the Fear Soul-Binding Array buried in the illusion.

For example, at this moment,

When the cold wind blew from outside, even someone as strong-minded as Zhong Yi couldn't help but feel a chill down his spine.

"Junior Brother Lu is really amazing. The temperature difference effect is so impressive."

Zhong Yi smiled and muttered to himself, then followed everyone into the haunted house.

The old, poorly repaired wooden door was pushed open with a creaking sound that was particularly harsh in the silent air.

Inside the dark and haunted house, there was only a lantern on the wall of the main room, flickering with a dim flame.

As the four people pushed open the door, the flames shook violently and suddenly went out.

There was a dead air in the air.

"Haha... Old Devil Lu is really something. He actually uses these low-level methods to scare us... Hahaha..."

Zhou Qiaoling's laughter sounded a little dry.

He smiled and took out a spirit cage from his backpack.

This is a free basic lighting tool given on the carriage.

It contains a glowing ore engraved with a magic circle, which can illuminate a certain area when taken out.

Because it is a first-level prop, there are many impurities in it and the visibility is very poor.

"The spirit cage alone is still too dark... Lao Zhou, go light the lantern."

Looking at his declining sanity value, Zhong Yi frowned.

"Why, Lao Zhong, are you afraid of the dark too?"

Zhou Yue teased cheerfully.

"I'm afraid of hammers! Don't you know that if it's too dark around you, you'll lose sanity?"

"I think you're just scared...otherwise why don't you go by yourself?"

"Are you looking for an excuse for not daring to do it?"

…

The people kept chattering, and the brave Mu Ya walked forward, picked up the match under the lantern and lit it again.

As the fire lit up, the rate of decline in sanity value slowed down.

The four of them looked around, taking in their surroundings.

The house is not big, but its structure is extremely depressing. Just walking in it will make you feel suffocated and dull.

Mu Ya and Zhou Yue lit up all the lanterns in the surrounding rooms one by one, and the whole house became a little less gloomy.

Sanity value also began to rise slowly.

Zhong Yi sat on a chair in the main room, looking at the book in his hand.

This is a prop given by the system, which contains detailed records of various knowledge about evil things.

"Our mission is to determine the type of evil creature..."

"The various magical weapons on the carriage are all key props for investigating the characteristics of the evil creatures."

"Each evil creature only operates in a specific area, which means... we need to find this area first, the [Haunted Room]."

"The [Haunted House] is colder than other places because of the heavy yin energy..."

Zhong Yi pinched his chin and muttered to himself.

Faintly, he seemed to have found the way to play in the illusion.

“Bang!”

A hand suddenly pressed on Zhong Yi's shoulder. He shuddered and looked up.

Gang Tu and the smirking Zhou Yue looked into each other's eyes.

"No way, Old Zhong, this can scare you?"

“…”

Zhong Yi held his forehead speechlessly.

"I don't know if it's just my imagination... After our sanity level dropped, we seem to have become much more sensitive to our surroundings."

"Take out the word 'we', it's just you!"

Zhou Yue teased with a smile.

"By the way, what were you mumbling about just now?"

Zhong Yi pointed to the book containing information about evil creatures and said, "Look, I've found a way to get through this illusion... The first step is to find the haunted room with the heaviest yin energy."
