After rushing up to the large tree, Ruri instantly thrust the Big Ball Rasengan in his hand out in front of him.
When the Big Ball Rasengan touched the tree's surface, it inflicted severe damage, twisting the wood bit by bit beyond recognition. Finally, unable to withstand the power of the Big Ball Rasengan in Ruri's hand, the tree burst apart from the middle.
Seeing the destruction the Big Ball Rasengan had caused, Ruri looked astonished and said quietly, "Holy crap, this is seriously powerful! And the Big Ball Rasengan is still only at the beginner level. Once it reaches the advanced level, its power will be unimaginable!"
After taking a few looks at the trunk destroyed by the Big Ball Rasengan, Ruri lowered his head and examined his palm. He found nothing wrong, but when he checked the amount of chakra in his body, he said in surprise, "What I didn't expect was that this Big Ball Rasengan would use up so much chakra!"
"I never expected a single use of the Big Ball Rasengan to consume a third of my chakra. That really caught me off guard! No wonder only Naruto can use this Big Ball Rasengan. He has enough chakra in his body to use it countless times! It looks like, besides advanced ninjutsu and exceptional talent, the amount of chakra in your body is also crucial!"
Ruri did not go on to practice the next ninjutsu. Instead, he sat right down beneath the large tree to replenish his chakra. If he kept expending it like this, the chakra in his body would soon run out, and then he would not have the strength to walk home!
*Looks like I'll have to find a way to increase the chakra in my body a little! Having much more
