Chapter 143: Mysterious Phenomenon

The aura around the room swelled to a terrifying level, forcing most of the Fletcher Castle's residents, whether the soldiers or servants, they all had to flee the area, unable to withstand the overwhelming pressure of lightning and thunder.

Boom! Then, with a powerful eruption, the dense lightning domain vanished, leaving behind a calm yet formidable aura.

"Success," Apollo and Old Man Aragon murmured in unison, understanding that Apollo's master had successfully made his breakthrough.

A sense of pride and relief washed over him, knowing his master had become even stronger.

"Haha, kid, it looks like your master has now become an honoured grandmaster," Old Man Aragon remarked with a smile as the intense aura began to subside. Despite their frequent verbal sparring, the warmth in his voice revealed the deep bond of friendship he shared with Apollo's master. Old Man Aragon was genuinely happy for his friend's success.
