"No…no…that…" the rat counsellor said as he backed away.
"Let me guess," Cheng Xiu said, "By destroying those torches I can widen the chasms which will devour the rats who are defying the Tower faster."
The rat counsellor shivered in fear. It realised that this human should be killed immediately. If the human goes out and reveals this to her companions then they were doomed and everything they did till then, and the sacrifices that they made, who be for nothing.
He started to attack Cheng Xiu continuously with its poison claws.
Cheng Xiu expertly dodged them, her speed fast and became faster with each attack.
The counsellor started to attack without any rhyme or reason, madly wanting Cheng Xiu to die and that was his only goal now.
The climbing could wait and there were still four other counsellors with him. Even if he failed, they would succeed. But this dangerous human could not leave.
