Karna started to climb the giant tree. The climb was difficult as the tree did not have many grooves to gain footing , and for some odd reason , it was extremely taxing on stamina.
Karna had to gulp many stamina potions to keep up with the climbing..... About 50 minutes later he finally reached the point where his hands gripped the giant hole made in the tree to gain access into the tree centre.
"Finally !!! " Karna exclaimed as he laid flat on the surface for the first time in the hour. He was exhausted completely , it was a tiring endeavour.
Karna wanted to curse monkey King luffy , who makes a treasure trove in a tree especially when it is soo hard to climb!
" Curse you luffy!!! " He shouted as he forced his body to move and stand up.
Karna looked around the room he was in , and in the entire room there was only a circular structure in the centre.
