Multiplier of universes

As Shion and Lina stepped through the academy's gate, they were engulfed in a brilliant blue light, forcing them to close their eyes for a moment. When they reopened them, they found themselves standing in a massive hall, surrounded by ancient stone walls inscribed with glowing magical runes. The place resembled a grand examination chamber, yet strangely, no one else was present.

Before they could make sense of the situation, a deep voice echoed throughout the hall as if it came from the heavens themselves:

"Welcome, new challengers. Before you stand three trials, each designed to test a different aspect of your abilities. Only those who pass will earn the right to enter the academy."

Lina and Shion exchanged glances before Shion calmly asked, "What are these trials?"

At that moment, three portals materialized before them, each distinct from the others. The first was engulfed in blue flames that flickered ominously, the second was shrouded in a dark mist that sent chills down their spines, while the third was transparent, appearing as a window into another dimension, its contents hidden from sight.

"The first trial: The Trial of Strength. You must defeat a magical beast within the flames."

"The second trial: The Trial of Intelligence. You must solve a complex riddle within the shadows."

"The third trial: The Trial of Willpower. You must face your deepest fears within the illusions."

Lina felt a tinge of anxiety as she gazed at the three portals, while Shion carefully assessed the situation. He knew he had the power to multiply anything, but he wasn't sure what awaited him inside each trial.

Lina whispered hesitantly, "What do you think? Which one should we start with?"

Shion smiled calmly and replied with confidence, "Let's start with strength… it should be the quickest."

He stepped toward the portal of flames, and the moment he touched it, an intense heat surged through his body before he was pulled inside with astonishing speed.

This was the beginning of his first trial…
