Seven Lù muttered in his youthful voice, "...How could Seven Lù possibly solve Master Su's problem?"
Xia Chujian said calmly, "Looks like your level isn't high enough, Seven Lù. I can find someone to upgrade you."
The word "upgrade" seemed to make Seven Lù freeze completely.
It did not speak for quite a while.
Xia Chujian waited for a while, thinking Seven Lù had started using its computing power on the calculation. When no response came after a long time, she could not help calling out.
"Seven Lù?"
There was no answer, nor did any Childish Graffiti Font appear on her Eyepiece Display Screen.

Xia Chujian comforted herself and gradually felt at ease.
However, she did not wait long.
About fifteen minutes later, an electronic synthesized voice unfamiliar to Xia Chujian sounded inside her Fully Enclosed Helmet.
"Master!
