Survival in an apartment, starting with a stroke of luck on a plane

Lin Yu looked at the mother and daughter sword spirits with their contrasting personalities and waved his hand: "It's alright, there's no need to be so reserved, we're all on the same side."

He pointed to the castle, looked at Liu Xiangxiang, and said, "Sister Xiangxiang, I do need your help with something."

This castle is too big. Searching using conventional methods is too inefficient and may cause me to miss some hidden places.

You are spirits, capable of penetrating walls and floors, and your search range and detail far surpass mine.

Could you help me thoroughly explore this castle, especially those places that look like they have hidden levels, secret rooms, or underground spaces?

Look for any unusual items, symbols, written records, or... anything that seems off.

Liu Xiangxiang immediately understood Lin Yu's idea and said seriously, "Don't worry, benefactor, leave it to us."

Liu Xiangxiang and the others are sword spirits born from the Evil Ghost Sword. It can be said that as long as the Evil Ghost Sword is not destroyed, they will not die, but will only be injured, making them very suitable as scouts.

The only thing to be careful about is that using them consumes a lot of resources; they consume one point of durability every minute, so they cannot be summoned for a long time. It's a pity that Lin Yu hasn't subdued any ghosts yet; if he had, he wouldn't need to use Liu Xiangxiang and the others.

Then, Liu Xiangxiang and Liu Yue'er's figures seemed to merge into water, instantly passing through the stone wall beside them and disappearing from sight.

Lin Yu stood with his sword in hand, waiting for the two spirits to finish their search.

Time ticked by, and the castle was deathly silent except for the howling of the wind through the broken walls. Lin Yu's mind maintained a faint connection with the sword spirit through the Demon Sword, and he could vaguely sense that they were rapidly traversing and exploring every corner of the castle.

About seven or eight minutes later, two beams of light flashed, and Liu Xiangxiang and Liu Yue'er's figures reappeared in front of Lin Yu. Liu Xiangxiang said, "Benefactor, I have finished exploring the main part of the castle."

Most of the area is in ruins or empty, and the remaining items are similar to those you found before, with nothing particularly unusual.

No strong evil energy or unusual energy fluctuations were detected.

Upon hearing this, Lin Yu's heart sank slightly. He then looked at Liu Yue'er, whose search direction differed from Liu Xiangxiang's. He wondered if she had made any discoveries.

Liu Yue'er blinked her big eyes and excitedly floated to Lin Yu, pointing to the ground beneath her feet: "Brother, brother, Yue'er just crawled down really deep underground to play and found a dark room down there, not far from where we are standing."

"An underground room?" Lin Yu's spirits lifted; he had indeed overlooked something. "Yue'er, exactly where is it?"

"Hmm..." Liu Yue'er tilted her head and thought for a moment, then pointed to a corner of the side fortress hall: "It's over there, Yue'er will take brother there."

After saying that, she darted into the ground again.

Lin Yu immediately followed.

Guided by Liu Yue'er's spirit, he arrived at a spot on the ground in the corner of the hall that appeared perfectly normal.

The ground here is paved with huge bluestone slabs, just like the rest of the place.

Liu Yue'er poked her little head out from under the stone slab and pointed to the ground: "Brother, there's a passage under this big rock that leads all the way to that dark room. It's huge inside!"

Lin Yu squatted down and carefully examined the huge bluestone brick. He tapped it with his hand, and it sounded dull and solid, probably because it was too thick, and it didn't sound hollow.

He groped along the edge, trying to find the hidden mechanism, but after searching through all the crevices, he found nothing but dust and rubble.

"Moon, is there any danger in that underground room? Did you go in and check?" Lin Yu asked cautiously.

Liu Yue'er shook her head, looking innocent: "There's no danger. There are just some broken wooden boxes and a few stone figures inside. Yue'er went around in there several times, and nothing happened."

Lin Yu felt somewhat relieved. He patted Liu Yue'er's head (although it was only through her spirit form, the gesture expressed approval): "Yue'er, you're amazing! Thank you so much this time!"

He then looked at Liu Xiangxiang beside him and said, "Sister Xiangxiang, you've worked hard too."

He picked up two unleveled [Soul Essence] that he had prepared: "These are for you, to replenish your energy."

The Soul Essence contains pure soul energy. When the sword spirit absorbs it, it can restore the durability of the Demon Sword and slightly enhance the strength of the two sword spirits.

When the soul essence approaches the sword spirit, it emits a soft light, and strands of pure soul energy are absorbed by them.

Both Liu Xiangxiang and Liu Yue'er showed a look of comfort on their faces, and the durability of the Demon Sword also increased by two points.

"Alright, you guys come back and rest now." After absorbing the spirit, Lin Yu put it back into the Demon Sword.

Now, the only remaining question is how to open this bluestone brick.

Since there are no mechanisms, we can only resort to brute force.

Lin Yu took out a crowbar from his backpack, which he had found in the backpack of the burly man he had killed earlier. He plunged the tip into the crack at the edge of the bluestone brick.

He took a deep breath and pressed his arms down sharply.

"Hah—!" With a low shout, Lin Yu exerted all his strength, reaching a power of eleven points, twice that of an ordinary person, in an instant.

Creak... Crack!

The heavy bluestone bricks, under the influence of the lever principle and Lin Yu's strength, emitted a teeth-grinding friction and cracking sound.

Stone chips fell softly from the edge.

The gap widened, and finally, with a muffled thud, Lin Yu pried open the entire massive bluestone brick, revealing a dark, narrow opening just wide enough for one person to pass through.

A chilly, damp air, thick with the smell of dust and decay, swept over us.

At the edge of the cave entrance, an ancient wooden staircase extends downwards, disappearing into the darkness.

Lin Yu shone his flashlight downwards; the stairs looked old, but the wood seemed quite sturdy.

He tentatively stepped on the top step, then stomped on it a few times. The stairs made a dull "thump-thump" sound, but did not seem loose.

"Looks like it still works."

Lin Yu felt relieved.

He crawled into the hole, but instead of going down immediately, he dragged the heavy bluestone brick back and put it back over the hole.

That way, even if someone comes, it will be difficult to notice anything unusual from the outside.

After doing all this, he turned on the flashlight again, holding the gun in his right hand and the flashlight in his left, and carefully walked down the wooden ladder.

The stairs weren't long, and soon his feet touched the ground.

This is a not-too-large stone-built basement, about three meters high and about fifty or sixty square meters in area.

The air was thick with the smell of dust and rotting wood.

As the flashlight beam swept across, the first thing that caught the eye was the "broken wooden boxes" that Liu Yue'er had mentioned—five oak boxes of different sizes, covered in dust and cobwebs, with some parts already rotten.

Lin Yu remained vigilant, slowly stepped forward, and carefully pried open the heavy lid of the first box with a crowbar.
