"Now we'll begin training. The first thing you need to do is climb trees!" Kushina said.
"Wait, we've already graduated and we're only starting tree-climbing training now?" At that moment, the Konoha ninja were all utterly bewildered.
"Since when was that a rule? In the future?"
"It must be the future. Didn't you see that Hatake Sasuke kid is the son of genius Kakashi Hatake? The current Kakashi is still so young, yet Sasuke is even older than his father."
"Damn, I really didn't notice that." Everyone's eyes widened in disbelief.
"Climbing trees? Wait, climbing trees needs training?" Naruto asked in confusion.
"Of course it does. Watch carefully." As she spoke, Kushina walked up the tree trunk and eventually hung upside down from it. "This is the tree climbing I'm talking about."
"How do we do that?" Naruto continued asking.
"It's simple. Gather chakra beneath your feet. Too much chakra will bounce you off, while too little won't let you stick firmly. You need to control your chakra to just the right amount to stand steadily on the tree trunk. Then train until it becomes instinctive. Once you reach that point, your tree-climbing training will be complete." Kushina flipped down from the trunk and threw out three kunai. "All right, each of you pick a tree and start training. Use the kunai to mark how high you get."
"Alright, watch me." Naruto immediately grabbed a kunai and prepared to rush out.
"Wait!" Sakura suddenly shouted. "Teacher Kushina, can this really make us stronger?"
"It can make them stronger, but you have too little chakra. Even if you master tree climbing, your growth will be limited. But that's fine. Train it first, and once you succeed, I'll teach you other methods."
"Then I won't hold back." Sakura immediately rubbed her hands
