'Dual-drive engine?'
If it was told by an engineer, the 5 people in the parlor would not be surprised; however, it was told by Fire Dragon Hermit...
Watching Zhang Tie's tower-like figure which was as powerful as a violence machine in ancient times and his bald head which only lacked the slogan "I'm the boss", the 5 people in the room widely opened their mouths at the same time.
"Did...did...Hermit...invent it?"
The eldest man in the room asked Zhang Tie with a dumbfounded look.
"Yup, don't I look like a scholar? Knights should be muscled with the simple mind?" Zhang Tie goggled at the old man. The old man immediately felt an overwhelming stress and almost had a pee.
"No...no...I didn't mean that...I mean...Hermit..."
Being intense, the old man stammered. Only in a few seconds, the old man's forehead had been covered with big sweat drops.
