Overpowering

Vylyss was standing before Noan, feeling an immense surge of power. 

She raised her hand, and a dark energy sphere appeared like a tennis ball and hovered above her palm like a tennis ball. 

"Vylyss, follow me into the trial space. I can only bring you with me this time," Noan said. "I hope you will do your best." 

Upon hearing Noan, Vylyss immediately became serious. She furrowed her brows and replied, "Yes, Master. I will not disappoint you. I swear on my life." 

Noan, seeing Vylyss' expression, understood why she was so determined. 

After letting Vylyss enter the 'Combat Simulation Room' to truly control her power after the upgrade, he immediately commanded the System: "Accept mission to select Class." 

[Ding! You may bring one hero into the trial space. Who will you choose?] 

"Vylyss!" Noan answered without hesitation. Currently, Vylyss is the strongest hero he owns, and he would choose her.
