In the outer court of Moon Illumination Sect, an ordinary duel invitation would only need the fingerprint from one elder or two outer court deacons before it was considered valid.
Only a Death Duel invitation would need the fingerprint of two outer court elders to be valid.
Judging by how Feng Fan went to look for two outer court elders for their fingerprints on the duel invitation, one could easily tell what kind of duel invitation it was. There was no doubt it was a death duel invitation.
"I've heard nothing of Senior Brother Feng Fan and Duan Ling Tian being mortal enemies… Isn't this death duel invitation a little too sudden?"
"Perhaps some enmity exists between them that we're not aware of. Otherwise, why would Senior Brother Feng Fan issue a death duel invitation to a stranger who had just recently entered the sect?"
"You must be right."
…
Soon after, the news of Feng Fan issuing a death duel invitation to Duan Ling Tian spread in the outer court, causing an uproar.
