There are stairs not far away, and it looks like there should be several floors here.

Let's explore the first floor first.

After entering the door on the left side of the first floor, there is a staircase, and after going down the first floor, you will come to a large room, and in the middle of the large room is a large dining table, which can sit down and eat together for a dozen people.

There were some bottles of fruit on the table, but they were all dusty, and there were some cabinets and other furniture against the wall, making it look like a restaurant.

After searching for a whole circle, basically finding nothing, Lu Chao went up the stairs back to the hall, and went to the door on the right side of the hall on the other side.

Lu Chao found an altar by the wall of the room, on which were placed several sets of white robes, as well as text instructions.

"Place the body of the deceased, and his soul and body will be reshaped."

Lu Chao estimated that this altar might be related to Cao Cao's corpse mission, but there were no obvious clues now.

There is an iron door in the innermost part of the room on the right, but it is locked, the kind that must be opened with a key, and it seems that there may be some secret hidden inside, or there may be a treasure chest.

After exploring the first floor, Lu Chao walked up the stone stairs to the second floor.

The temperature on the second floor is a little lower than on the first floor, and there is a slight breeze blowing from an unknown corner, which makes people feel very uncomfortable.

Walking up the stone staircase to the second floor, facing the staircase is a half-open iron door, which is also a small and large hall.

Lu Chao walked to the window, the curtain covering the windowsill was wet, and there were still a lot of water stains on the ground below, as if something had crept in from the window.

Standing by the window, the sound of rain and thunder outside became clear, Lu Chao stretched out his hand and lifted the curtains, just as a thunder exploded outside, and the violent lightning was extremely white and bright, which made Lu Chao's eyes a little dazzling.

It took Lu more than a moment to regain his vision, and through the transparent window made of magic crystal, the pouring rain was pouring down from the sky.

Neither word can describe exactly how heavy the rain was outside, and the faint light of the fire inside made it impossible to see what was going on outside the castle, and the super-dense rain completely obscured everything.

Just as Lu Chao was looking out the window, a vague voice suddenly came from behind him.

Lu Chao hurriedly turned his head and found that there was no one behind him.

The muffled voice was gone.

Lu Chao walked briskly to the side of the stairs and looked up, then down.

The entire corridor was so quiet that it didn't look like anyone had ever appeared.

When a person suddenly came to such an environment, although Lu Chao was very bold, he still had a creepy feeling at this time.

Lu Chao returned to the window again, and after thinking about it, he pulled the window bolt abruptly.

The wind outside was very strong, and as soon as the window bolt was opened, the window was blown open by the wind, and the pouring rain was blown into the hall by the wind, drenching Lu Chao's whole body, and he couldn't help but shiver.

The sound of wind, rain, and thunder was so loud that it filled the entire eardrum, making it almost impossible to hear any other sound.

The wind blew into the hall on the second floor, not only bringing in a lot of rainwater, but also blowing out some of the torches on the wall on the second floor.

"Bang!"

A muffled sound smashed on the wall outside the window, startling Lu Chao, and then a demonic wail came from outside the window, and an extremely ugly and hideous monster appeared in the window with a pair of its fleshy wings, but because the window was too small, it couldn't rush in.

Lu Chao hurriedly closed the window and stopped the monster out of the window.

After the window was closed, the torches in the room slowly burned on their own, and after the fire was a little brighter, my heart seemed to feel warmer.

After a while, the faint voice of speech rang out again, as if coming from upstairs.

Lu Chao followed the sound of words and ran to the fourth floor in one breath.

The muffled voice disappeared again.

The layout of the fourth floor is very simple, it is a large empty room, the large room has several windows, but the windows are locked and cannot be opened, through the windows you can see and hear the wind and rain outside, and then the occasional lightning, nothing else can be seen.

After some exploration found nothing, and after confirming that there was no staircase to go down, Lu Chao went down to the third floor.

The situation on the third and fourth floors is similar, but there are a few more rooms, and after entering, it feels like nothing special, and the windows are locked.

Lu Chao went down to the second floor again.

While exploring the second floor, there was a sudden knocking sound from upstairs, as if someone was walking on it.

This time, Lu Chao didn't go up to investigate again.

It felt like the game was playing tricks, trying to scare him and make him extremely afraid of losing his mind.

It's a pity that Lu Chao was not frightened.

After discovering nothing, Lu Chao began to suspect that the next clue was on the monster outside the window.

I have to open the window again.

After calming down, Lu Chao walked to the window and pulled the bolt, opened the window, and quickly retreated to the wall on the other side of the room.

Despite his quick movements, he was drenched in water. The wind mixed with the torrential rain whistled in, and immediately blew out most of the torches in the hall on the second floor.

Lu Chao had experience, knowing that the monster would pounce after half a minute, he subconsciously looked at the stone wall behind him, but found that there was a picture on the stone wall!

"Bang!"

The huge monster outside the window slammed into the open window.

After Lu Chao confirmed that the monster could not enter the window, he carefully studied the picture on the stone wall.

The picture on the stone wall is very similar to the architectural layout of this ancient castle, I don't know who carved it on the wall, the lines are already very blurred, and I can only vaguely recognize the distribution of rooms on each floor.

From the picture, it seems that there is not only one hall on the second floor, but also two rooms on both sides, forming a 'concave' pattern on both sides of the hall.

The second floor of the entire castle is this kind of 'concave' character layout, the place where Lu Chao is currently standing is at the bottom of the 'concave' character, judging from the architectural drawing, there is a room on both sides stretched forward, forming the upper half of the 'concave' character.

However, the hall on the second floor is square, and there is no other door in it except for the large iron door that comes in by stairs.

The problem should be in these two extra little rooms.
