After the time it takes an incense stick to burn, Ning Fan had beaten the Wansheng Dragon King down.
The test result satisfied Ning Fan greatly: If he doesn't use the Life-Slaying Sword, his other methods can't effectively harm the Wansheng Dragon King; but with the Life-Slaying Sword, the Wansheng Dragon King can withstand hundreds of strikes before getting hurt, much more resilient than the incomplete Eternal Ghost Soldiers.
This means that even if Ning Fan's enemies happen to have some means to counter immortal creatures, they can't kill the Wansheng Dragon King in a single strike.
If enemies lack such means, even a First Order Quasi-Saint would struggle to kill the Wansheng Dragon King.
"You are not bad!" With another powerful ally, Ning Fan was in a good mood and praised the Wansheng Dragon King.
"Thank you for the praise, master."
