The Kowtow at the Critical Moment

The old man who was holding the sword seemed to be terrified by the situation. He subconsciously let go of his hand which was holding the strong dark-skinned person and turned to look at the Vigilante A in the air. 

The dark-skinned person did not show any joy after his narrow escape, but was still trembling without any emotion on his face. 

"XXXX@$HF%XX..." said the old man with a croaky voice.

"X@$&XXXXXX..." the Vigilante A replied with the same words.

…

Fang Ning had just texted Zheng Dao and looked outside. He was speechless.

"Can't you both just speak Chinese?"

"Of course I can, but he can't…" said the System confidently.

"You're right, I don't even know how to reply," Fang Ning was helpless and went into Anderson's office.

Surely, he knew the reason for the System speaking the old man's language. In the Draconic Penitentiary, there were countless Descendants of the Upper Realm.
