He took a deep breath, then resolutely stepped into the pool.
In an instant, David felt a powerful force envelop him, and his consciousness began to blur.
When he opened his eyes again, he found himself in a strange environment.
This was an illusion realm composed of light and shadow, surrounded by a barren desert, with thick black clouds looming in the sky and thunder rumbling.
David felt a suffocating atmosphere rushing towards him, making him feel a little breathless.
"Where is this?" David murmured to himself.
"This is your inner world." A voice sounded in his ear, "Here, you will face your inner fears and doubts."
David looked around and found that a gigantic shadow suddenly appeared in the desert, gradually taking shape into a monstrous beast.
The beast had a ferocious form, with red eyes, emitting deafening roars as it charged at David.
David was startled in his heart, but he quickly calmed down.
