The Ancient Corrupt Claw Dragon not only has a stronger desire to attack, but also has more moves and increased damage values overall.
Seeing Instructor Ding and the Dealer dodging around, not daring to take damage head-on, Chen Tingquan was even more cautious.
Getting scratched even once could result in being infected with the Mad Dragon Plague.
If it were a lower level of the Mad Dragon Plague, it wouldn't be so bad. He could just withstand it for a while, but the real fear was that it would bounce between players, possibly killing him before he could react.
The Ancient Nine Dragon had a thick blood bar, showing no signs of damage even after being hit for a long time.
This game doesn't display a blood bar, but there are ways to roughly gauge a monster's health, like observing damaged parts on the monster's body or changes in its movements.
