Uchiha Mitsuki's angry voice did not affect Itachi. He still faced Shisui's Susanoo with a serious look on his face and released the powerful fire ball technique.
Bang! Bang! Bang!
One after another, red fireballs hit the surface of the green Susanoo, exploded, burned, and extinguished without causing any waves.
Little Sasuke in his arms also excitedly clapped his chubby little hands because of his dazzling fire escape.
"Art fire escape ho fireball!"
Itachi gasped, used up the last of his chakra, and created a fireball the size of a lollipop, blasting it towards Shisui's Susanoo.
Boom!
After a soft sound, the fireball that hit the Susanoo's surface disappeared immediately.
"The gap is so big..."
Itachi sat down on the ground, looking at Susanoo not far away who was still intact as before, feeling powerless. Although the little Sasuke in his arms could not figure out the situation at this time, he obediently rested his head on Itachi's chest.
forward.
After removing Susanoo, Shisui, who had just walked over, couldn't help but feel a little envious.
“That’s it for today!”
He said with a smile, taking out a towel and handing it to Itachi who was sitting on the ground.
"good."
Itachi took the towel, gently knocked off the little hand that his brother had stretched out to make trouble, and wiped the cold sweat from his head.
"What's wrong? Are you unhappy?" Looking at Itachi's tense little face, Zhisui suddenly felt a little funny, "Is it because of the training just now?"
"Um……"
Itachi put down the towel and nodded gloomily.
He didn't know why his fire escape couldn't defeat Shisui's Susanoo!
Shisui smiled and used a head-butt kill on Itachi, and then said very proudly: "Susanohu is the ultimate power of the Uchiha clan. How could it be broken by a merciful ninjutsu like Go Fireball?"
Hearing this, Itachi felt even more uncomfortable. He only knows this now.
This scene was seen by Uchiha Mitsuki. In order to prevent Itachi's young heart from being shocked, he hurriedly flapped his wings and flew over.
"Having said that, there is one thing, Itachi, you definitely don't know. When Shisui was the same age as you, his strength was far inferior to yours."
"Really!"
Itachi raised his head in surprise, and the embarrassment on Shisui's face undoubtedly confirmed Uchiha Mitsuki's statement.
"Teacher, can you save some face for me!"
Shisui Jun blushed when he thought of his ridiculous showoff when he first met Crow Sage.
"Ha ha!"
Uchiha Mitsuki laughed loudly and did not continue to tease Shisui. Instead, he fell on his shoulder and shared his knowledge to enrich the two of them.
"As we all know, chakra is composed of physical power and mental power. If a single physical power or mental power is too strong, a fatal disease will break out, which is what we often call blood disease."
"Blood disease?"
As the son of the clan leader, Itachi had heard a little bit about this.
"Yes."
Uchiha Mitsuki nodded and gave Itachi a deep look. The slightly ignorant young man in front of him at this moment would die young due to the hemorrhagic disease caused by the Mangekyō Sharingan.
Shisui also wiped away the smile on his face because of this topic.
"However, don't worry too much." Seeing the serious expressions of the two, Uchiha Mitsuki comforted him with a smile: "Although Fugaku has lost the ability to use the Mangekyo Sharingan, you are different."
"Are we different?"
After hearing this, Shisui's eyes widened and he looked very surprised.
Itachi on the side hugged the active Sasuke tightly and listened carefully.
"Teacher, do you mean that the Mangekyō Sharingan can be used forever?" Shisui asked.
Uchiha Mitsuki nodded: "Yes, you should feel it, right? During this period, using the Mangekyo Sharingan so frequently, is the load on your eyes not as heavy as you think?"
Having said this, Uchiha Mitsuki tilted his head and glanced at Shisui who was thinking. Through getting along with him over the past few years, he vaguely discovered something strange about Shisui.
"The guy in front of me is either a time traveler or a reborn person."
However, Shisui didn't know what Uchiha Mitsuki was thinking at this time. After hearing Uchiha Mitsuki's words, he suddenly said: "Teacher, it's because of those injections in the school, right?"
"Clever! In order to avoid the outbreak of blood disease, Konoha's Science and Technology Department has specially developed body strengthening potions with different concentration gradients."
"For students with strong mental strength, such as children from Uchiha, Kurama, and Yamanaka families, different concentrations of Uzumaki serum are used."
"And for those students with strong physical strength, Kurama serum or Uchiha serum is used."
Shisui was completely shocked after hearing this.
Let alone the serum in his previous life, he had never even heard of this aspect.
After a while, Shisui suppressed his excitement and looked excitedly at the crow that landed on his shoulder.
"Teacher, do you mean that I can use the Mangekyo Sharingan at will?"
Uchiha Mitsuki looked at Shisui meaningfully, and it took a long time before he said: "No! The power of the Mangekyo Sharingan is quite powerful. If you want to completely control it, you must inject another reagent."
"What is it?"
After hearing this, Zhisui almost jumped up with excitement.
It doesn't look like a time traveler... Uchiha sighed secretly when he saw the moon, flew off Shisui's shoulder, transformed into a human form, and handed a glass test tube to Shisui.
"This contains Hashirama's serum. After injection, you can completely control the power of the Mangekyo Sharingan."
"However, there is a certain fatality rate."
At this time, the rays of the sun shone on the string of gems on Uchiha Mitsuki's chest, making Shisui and Itachi unable to open their eyes.
Then, Uchiha Mitsuki said again: "Your clan leader Fugaku was afraid that he would die suddenly after the injection, so he would rather go blind than inject it into his body."
Itachi suddenly retorted: "Teacher, my father did not inject Hashirama's serum not because he was afraid of death, but because..."
Because of the harsh light, Weasel simply closed his eyes.
At this moment, a very deep voice suddenly came from not far away, directly interrupting Itachi.
"It's because he can't die yet. He has to protect the family for his friends."
"Father!"
This voice was too familiar to Itachi. He hurriedly stood up with Sasuke in his arms and turned to look in the direction from which the voice came.
"Long time no see, see the moon!"
Fugaku came from a distance, but he did not linger in front of his two sons, but walked straight towards Uchiha Mitsuki.
At this moment, looking at the face that had only existed in his memory for the past few years, Fugaku's nose felt sore. Then, he opened his arms wide and rushed towards the young man with the sun reflecting on his body, intending to hug Uchiha.
A full embrace, but a lonely one.
"Jianyue, you...!"
Fugaku stabilized his unbalanced body and looked behind him in surprise at the boy who passed through him like air.
