"What is this?!"
Xu Jingming's eyes widened abruptly, and his breathing quickened.
A plus sign had appeared after the ability rank. Didn't that mean the SS-rank Du Tian Divine Lightning could be upgraded with Ability Points?!
The sudden surprise made even the usually composed Xu Jingming's heart race, filling him with joy.
Ever since even one million Ability Points had failed to upgrade his ability last time,
he had temporarily given up on improving his ability, intending to upgrade his level and Battle Techniques first.
Yet he had never expected the opportunity to upgrade his ability to come so suddenly.
"Teacher Ling, come on, let's head back first."
Xu Jingming grabbed Ling Shuang's small hand and flew toward the cave.
When my S-rank Purple Heaven Divine Lightning was upgraded to SS-rank, the disturbance was enormous. It could be sensed across nearly a hundred kilometers.
This time, upgrading it into an SSS-rank metahuman ability would likely cause an even greater disturbance!!
Moreover, he had a vague premonition that this ability transformation might not be completed instantly like last time.
Therefore, he had to find a safe place first.
"Head back? Back where?" Ling Shuang asked doubtfully as he pulled her along through the air.
"Back to the temporary base near the cave."
Hearing Xu Jingming's words, Ling Shuang's pretty face immediately flushed slightly.
They had only just met, wasn't he being a little too impatient?
But when she thought of the side effects of Xu Jingming's Body Tempering Art, she understood.
That was true. They had already been in the Secret Realm for so many days. The side effects had probably accumulated to a terrifying extent.
Thinking this, Ling Shuang stopped speaking and allowed Xu Jingming to fly with her.
Yet Xu Jingming suddenly halted in midair and did not continue
