Suddenly ik-soo stands up .
Ik-soo: Everyone i have something to say (slips about to fall down ) 
Jayeha: catches ik-soo. Watch out mr priest it would be bad if u got hurt.
Iksoo: i have something to tell u all pls gather around and listen carefully.
Everyone gathers and sits in a circle ( like how people sit while playing truth and dare)
Iksoo : today when i was praying to the gods on the mountain near the waterfall . i heard many amazing and shocking things and a new revelation has come. In my sleep i saw  there was Yoona chan standing with 6 dragons. Hak and  yoon and su- woon. In the hyriuu castle. All smiling trimphantly.
(Everyone shocked)
Yoon : 6 dragons aren't there only 4 according to the legend !!!!
Ik-soo : that's what i was thinking about but seems like the legend is incomplete. There are some questions that haven't  been answered according to the legend king hyriuu came on earth in a human form to prevent chaos on earth but y did he have to come himself he could have given his blood to a warrior like the other dragons who would prevent chaos instead of him. Also y do the dragons continue to exist long after his death. Why did he choose kouka kingdom as his territory ?
(Everyone quiet and thinking)
Jayeha : i guess then we have to find the answers to these questions .
Kija :  To think there were other dragons out there on earth. I want to solve this mystery.
Yoon : Wait do u mean we have to complete the incomplete legend . (ik-soo nods) how on earth r we supposed to do that!!!!!!
Ik-soo: just like to solve a puzzle u 1st collect pieces right now u have alrady collected some pieces (the four dragons) but there is more to collect. Once u have collected all of them and arranged them properly the puzzle shall be solved.
Zeno : zeno loves solving puzzles!!
Yoona: lets go find other dragons.
Yoon :  Wait but we do not know anything about their locations !!!!!

Where do u think the rest of the dragons might be present ?  Do write ur guesses in the comments ..
