Kakarot, the strongest Hokage in history!.

Boom, boom, boom! Big storms came out of his mouth three times in a row.

  "This... is wrong! It's wrong!! I seem to have sensed it!"

  Wukong shook his little head and formed seals quickly. His chest bulged slightly. He opened his mouth for the seventh time and spit out a five-meter-long fireball. The fireball rushed to the open ground and burned crazily.

  "Wow! I succeeded!" Wukong shouted excitedly.

  The three members of Kakashi's team were even more stunned, staring at the big fire ball in silence for a long time.

  "How about it, Obito?"

  Goku asked Obito, "Did my ninjutsu succeed?"

  "Um···"

  Obito closed his mouth and nodded slowly, "It's not bad, it's barely a success."

  "That means I have learned a ninjutsu!" Wukong clenched his fists excitedly.

  Obito raised his eyebrows, coughed, and said:
  "Wukong, actually, this ninjutsu is only a C-level ninjutsu, it's not that difficult. You don't know the classification of ninjutsu yet, right?
  "Ninjutsu is divided into levels E, D, C, B, A, and S according to difficulty, from low to high!
  "Although it is just a degree of difficulty, the level also represents the power to a certain extent.

  "C-level ninjutsu is only at the chunin level. B-level and A-level ninjutsu are not that easy to learn."

  He glanced at Kakashi and continued, "The Chidori, which Kakashi developed recently, is an A-level ninjutsu and is very difficult to learn."

  "A-level ninjutsu! More powerful ninjutsu!" Goku looked at Kakashi, "Kakashi, can you teach me that bird ninjutsu?"

  "It's Chidori!" Kakashi glared at Obito and sighed helplessly, "I'll only demonstrate once, so you watch."

  "Thunder Dungeon Chidori!!"

  He quickly formed a seal, Chou-Mao-Shen, and then concentrated the Thunder Chakra on the palm of his right hand. Suddenly, a dazzling blue thunder light lit up on his right palm.

  At the same time, the sound of electricity, like the chirping of a thousand birds, also resounded.

  "Wow!!" Wukong was amazed. "It's so powerful! This ninjutsu can actually make electric current flow out of your palms!"

  Kakashi rushed out, lightning flashed across the ground, and his palm stabbed out, easily piercing a big tree in front of him.

  "Wukong, see clearly." Kakashi walked back, "Let's try it."

  "Okay!" Goku responded loudly. He imitated Kakashi's seal and began to condense the Thunder Chakra.

  The three of them looked at each other closely. After Wukong formed the seal, he gathered strength in his palms but there was no reaction at all. So he gathered more strength into his palms.

  They secretly breathed a sigh of relief. It was just a C-level basic flame ball ninjutsu. It would be unreasonable for Goku to learn an A-level ninjutsu so easily.

  "Why not!"

  Wukong tried three times but found that there was no response on his palm, "This ninjutsu is so difficult!"

  He took a deep breath, recalled what his master, Grandpa Kame Sennin, had taught him, calmed down, formed a seal, and then gathered the power in his body on his palms.

  Suddenly, a dazzling white light bloomed on his palm.

  "..." Kakashi and the other three looked at each other.

  "Chichi~"

  A faint sound of electricity sounded on Wukong's palm. Wukong sprinted away and easily penetrated a big tree in front of him with one palm.

  The three of them came over and looked at the spot where Goku's palm had penetrated. They were silent for a long time. After a while, Kakashi touched his chin and said:

  "Goku, your Chidori is a little weird."

  "Ah, what's wrong?"

  "The light is quite sufficient, but the condensed thunder and lightning is actually not that much. Logically speaking, it cannot be considered a true completion."

  Kakashi looked at the tree hole that penetrated even larger, "But the power of your Chidori is more powerful than mine, which is a bit strange."

  "As long as you can become stronger!"

  Goku didn't care much about this, and looked at them again, "Are there any more powerful ninjutsu?"

  "..." Lin and Obito looked at Kakashi. Kakashi felt helpless. The A-level ninjutsu "Chidori" was developed by him after a lot of hard work. He originally thought it could hit Goku. Who would have thought that he would learn it quickly after watching it once... (End of this chapter)
