The breeze was blowing, and the sun was shining down, "Why are the three of them gone?" Didn't they go through that door? Yu Qian was frightened, confused, vigilant, and instantly rushed out of his heart.

Yu Qian looked around and found that there was no one around, and the three of them disappeared without a trace in this moment. He felt a wave of fear and doubt, wondering if he was dreaming.

But in an instant, another door suddenly appeared behind him.

He turned back vigilantly, spotted the door, and slowly leaned towards it, but his hand was still vigilantly holding his sword.

Walking to the door, he noticed that there seemed to be no danger next to the door, and he slowly lowered his vigilance.

The door is surrounded by strange patterns of all sizes, and there appears to be a key socket in the middle of the pattern. However, Yu Qian didn't have a key, so he dismissed it, and he decided to use brute force to open the door with the key.

Squeak...

Boom...

With a loud bang, the door was opened, and it was pitch black inside, and Yu Qian took out a light stone to illuminate the surroundings. He found himself in a spacious hallway, the walls carved with bizarre patterns and symbols. Yu Qian walked cautiously in the corridor, the horror and curiosity in his heart intertwined.

Yu Qian's heart beat faster, and he nervously clenched the sword in his hand, ready to deal with the danger that might arise at any time. In this darkness, he didn't know what to expect next, but he knew he had no choice.

After walking for a while, Yu Qian found a dimly lit room. He hesitated, then cautiously walked inside. The room is filled with all kinds of ancient utensils and books, and it looks like an ancient study. Yu Qian rummaged through the bookshelves, hoping to find clues about this place.

Unfortunately, there is nothing on the shelves except for some books of strange colors.

Just as Yu Qian was leaving, but at this moment, Yu Qian's back actually began to emit a strange light, Yu Qian was puzzled and immediately turned around. He saw an ancient magic circle glowing on the floor behind him. He cautiously approached, trying to understand the meaning of this magic array.

"What is this?"

However, Yu Qian did not find any clues related to this mysterious place in the magic array. He hesitated for a moment, deciding to try to touch the magic circle. As soon as his hand touched the magic array, a powerful force instantly surrounded him.

When Yu Qian opened his eyes again, he found that he was already standing in a completely different place. Here is a vast grassland, the sun is shining, and birds are singing happily in the sky. He looked around and saw a majestic castle in the distance.

"Damn, why has it changed again, my hands can keep up, but my brain can't keep up." Yu Qian complained.

Yu Qian could only smile helplessly, and then cheered up again, and just after taking two steps, a huge castle appeared not far away, standing here.

Yu Qian glanced at it, and then walked towards the castle.

After a while, Yu Qian came to the gate of the castle. He took a deep breath, then mustered up the courage to push open the heavy door. There was silence inside the door, save for the sound of a breeze blowing through the hallway. Yu Qian walked cautiously down the hallway, looking around vigilantly.

After walking for a while, Yu Qian heard some faint voices. He walked in the direction of the sound and found a room hidden at the end of the hallway. He gently pushed the door open and cautiously stepped inside.

The room is filled with all kinds of ancient utensils and books, and it looks like an ancient laboratory. Yu Qian rummaged through the bookshelves, hoping to find clues about this place. Finally, he found a worn-out diary in a corner.

The owner of the diary is named Carlos and is the owner of this castle. He was once a brave warrior and later a magician. During an adventure, he discovers this mysterious place and is captivated by its magical powers. In order to study the power here, he set up a laboratory here to try to find a way to control it.

However, during an experiment, Carlos accidentally lost control, resulting in a massive explosion. The castle and laboratory were destroyed, but Carlos was lucky to survive.

But...
