Earth's catastrophe, crazy black crystals begin to wreak havoc

The friends know that they have successfully found the third artifact. This makes them feel happy and proud. They know they are only one step away from completing their mission.

Lisa Lun carefully removed the dragon pendant and placed it safely in the body bag. The power of this artifact made her feel solemn and exciting.

"We are getting closer and closer to success! Now we only need to find the last artifact to save the dragons and protect their future." Lisa Lun encouraged her partners.

The black dragon spread its wings and stood upright in the center of the hall, its eyes revealing firm belief.

"We have no retreat, only the way forward. We will overcome all difficulties and protect the dignity of the Dragon Clan." The Black Dragon's voice was full of determination and strength.

The six-armed cockroach noticed a large bronze door on the wall of the hall. The door is carved with a scene of a confrontation between a giant dragon and an evil dragon.

"This door may be the entrance to the last realm. We must solve the puzzle behind the door to enter it." The six-armed cockroach shared his discovery.

The friends walked to the bronze door and carefully observed the patterns and symbols on the door. They realize that it is a sealed door that can only be opened by the chosen one carrying three artifacts.

Lun Lisa opened the protective bag, she gently took out the three artifacts and held them tightly in her hands.

"Artifacts brought together can have greater power. Let's try to touch them together and see what happens." Lisa Lun suggested.

The partners formed a circle and connected the three artifacts end to end. Suddenly, a brilliant energy emerged from the artifact and surrounded them.

The bronze door began to slowly open, revealing a mysterious and magnificent realm. The partners know that they are about to enter the final challenge and decisive battle.

"Let's move forward together!" Lisa Lun led her friends towards the bronze door and entered the unknown territory.

Lisa Lun, the six-armed cockroach and the black dragon bravely move forward in the mysterious realm. They face the most unpredictable challenges and ferocious monsters. However, they firmly believe that as long as they work together and move forward courageously, they will be able to overcome everything, find the last artifact, and complete their mission.

Lun Lisa explored the mysterious maze alone, full of curiosity and expectation. Suddenly, her eyes were attracted by a stone statue. This statue is a grimace with a sinister face and cunning eyes.

\"Who are you?\" Lisa Lun asked curiously.

The ghost-faced man slowly opened his mouth and made a low voice: "I am the guardian of the labyrinth and know many secrets. The Dragon's Heart you are looking for is not a real artifact."

Lun Lisa was shocked, and she asked eagerly: "Where is the real dragon's heart? Why was the one I found before a fake?"

The Grimace smiled triumphantly and replied: "To find the true Dragon Heart, you must accept my challenge. By solving my puzzles, you will gain clues."

Lun Lisa gritted her teeth and accepted the challenge without hesitation.

The ghost-faced man's gaze became sharper, and he shook his body slightly, as if emitting a strange power. A golden light flashed, and Lisa Lun felt subtle changes in the surrounding space.

The ghost-faced man suddenly spoke and murmured to himself: "Dice, dice, are the key to solving the mystery. The mysterious power is ready to be revealed, and the dragon's heart will appear after solving it."

Hearing these words, Lun Lisa's heart moved, and she quickly formed a reasoning in her mind. She thinks the dice may hold valuable clues and decides to examine her surroundings carefully.

She walked around, observing every corner. Next to a pile of bones, she found a small, ancient wooden box. Lisa Lun opened it carefully, and there happened to be a crystal clear dice inside.

"Maybe this is the key!" Lisa Lun thought.

She picked up the dice and looked at them carefully. The dice were engraved with numbers and strange symbols. Lisa Lun tried to play with the dice to see if there was any hidden mechanism.

As she rolled the dice, the mood in the room suddenly changed. The grimace's smile gradually disappeared, replaced by an eerie silence.

"Crack, click, click..." Lisa Lun heard a series of sounds that were almost like those in a secret room.

She felt that she was in a more mysterious environment, and the ghost-faced man gradually lost the light in his hands and became dim.

"What did you do?" Lisa asked.

The ghost-faced man smiled slightly and replied: "This is the beginning of the trial. Forget the previous clues, you need to rely on intuition and insight to find the truth."

Lun Lisa felt a little anxious, but her heart was full of determination. She knew she had to deal with this unexpected challenge if she wanted to move forward.

Just as she was thinking about her next step, a wall in the room quietly moved away, revealing a new passage.

\"Let's go in and take a look, maybe the clues are there.\" She said to herself.

She walked closer to the passage, feeling the mysterious atmosphere that filled it. The passage is a rather long and slender corridor, with various strange symbols and patterns carved on the surrounding walls.

She took each step carefully, staring at the patterns on the wall. Suddenly, she saw a set of symbols forming a puzzle.

Some clues quickly flashed through Lun Lisa's mind, and she began to think about how to solve the mystery.

"The symbols look a bit like musical notes, perhaps cues for a melody?" she thought to herself, trying to piece together a logical clue.

She tapped her fingers against the symbols on the wall, trying to create a melody. Suddenly, she heard a faint voice respond.

"Yah~"

Lisa Lun was stunned. She didn't expect this method to work. She quickly tapped the symbols according to the melody again, making a louder sound.

"Eaaah~bang!"

As the last symbol was pressed, a secret door suddenly opened in the wall.

\"Successful!\" Lisa Lun said excitedly.

She walked into the secret door without hesitation and came to a more mysterious space. This space seems to be another world, surrounded by a mysterious atmosphere.

She sensed powerful magical energy in the room and looked around very carefully, trying to find clues.

Suddenly, she heard a voice ringing in her ears: "I am impressed by your intelligence."

Lun Lisa quickly looked around and found that the sound seemed to be coming from behind a closed door.

"Please tell me what you know." She decided to talk to the voice.

With a hint of sneer in his voice, he said: "Only by answering my questions will I give you the clues you need."

"Okay, I'd like to have a Q&A with you." Lisa Lun decided to accept the challenge.

"The first question is, what gets higher the more it is used and disappears when it is no longer used?" the voice asked.

Lisa Lun thought about it carefully and then replied: "Age."

"Clever! You got the answer right." The voice said approvingly. “Now, second question, what starts out small but gets bigger with use?”

Lisa Lun thought for a moment, and then answered confidently: "Fire."

"Your answer is correct again." The voice seemed more excited. "Last question, there are two snakes in the pile of stones, one fake and one real. How can you identify the real snake?"
