"What's going on?" Mu Li asked puzzledly.

At this moment, a figure appeared in front of her. It was the old man she had met in the space before.

"Little girl, although you have passed the test and obtained the treasure, there is still an opportunity waiting for you." said the old man.

Mu Li asked curiously, "What opportunity?"

The old man smiled slightly and said: "In this mysterious place, there is an ancient secret book hidden. If you can get it, your strength will be further improved."

Mu Li's eyes lit up: "Then how should I find it?"

The old man handed her a jade pendant: "This jade pendant will guide you."

Mu Li took the jade pendant, thanked him, and then followed the instructions of the jade pendant.

Along the way, we encountered all kinds of strange mechanisms and traps.

"This won't be a problem for me." Mu Li resolved the problems one by one with her wit and courage.

Finally, she came to a secret room.

"This should be the place." Mu Li took a deep breath and pushed open the door of the secret room.

On the stone platform in the center of the secret room, there was a secret book exuding an ancient atmosphere.

Mu Li was about to reach out to take it when suddenly a powerful force pushed her away.

"If you want to get the secret book, you must pass my test." A voice came from all directions.

Mu Li stood up: "Come on!"

The test began, and countless lights and shadows attacked Mu Li.

Mu Li used all her skills to fight against the light and shadow.

After a fierce battle, Mu Li finally passed the test and got the secret book.

"Haha, good, good!" The old man laughed, "There will be more difficulties and challenges in the future. You need to practice hard, not be afraid of difficulties, and never forget your original intention!"

Mu Li was about to ask something when her vision went dark and she lost consciousness.

When she woke up again, she found herself back in the spirit bracelet space.

"Master, you finally woke up!" Several little ones surrounded Mu Li nervously.

"How long have I slept?" Mu Li asked.

"Master, we don't know either. It feels like it's been quite a long time!" said the Nine Netherworld Butterfly.

"Oh no! Has anyone come to see me?" Mu Li asked nervously.

"Yes, they came in several waves, and then they disappeared." The little white fox felt a little strange.

"Could something have happened? I'll go out and take a look first!" Mu Li said as she flashed out of the space.
