In a secluded valley, a 4-year-old child was standing in a house on fire and surrounded by corpses, watching the fire. Orochimaru looked at the corpses around him and came to the child's side: "Serena, it seems that you have begun to get used to killing. ”

Serena turned his head to look at Orochimaru with an expressionless face, "Teacher, now that the traitorous ninja in the third place has been eliminated, are we going to Kikyo City next?" ”

"Yes, it's been two days, and it's time for us to go to the front line to support, but we still have one more thing to do before then."

Serena was puzzled when she heard this: "Teacher, what else do we have to do?" ”

"Serena, although you have started to get used to killing, the real battlefield is much more tragic than this, so continue to exercise your mind."

"I still have to exercise my mind, but there is only one day left, and I still have time to exercise? Teacher. ”

Orochimaru smiled wickedly when he heard this: "Serena, time is definitely enough, because it only takes a few seconds to do it." ”

"A few seconds, is it an illusion?"

"Serena is so clever, it's illusion! However, no one has been using this method to improve their morale so far, because most of the young ninjas who use this method can't bear the mental pressure and collapse. However, I believe that Serena will succeed and will you dare to try. ”

Serena fell silent when he heard this, and used illusion to forcibly improve his mind, in case he lost himself in the illusion, then he would collapse after the illusion was lifted, and he would not be able to pursue a higher realm in his life, and he would spend the rest of his life stuck in the lower ninja realm, which would be a big gamble, if he won, he would enter the peak faster, and if he lost, his ideal would not be realized, and he would waste his life. However, thinking of the metamorphosis of the later Hokage world, Serena still agreed with Orochimaru's opinion.

Orochimaru saw that Serena pondered for a long time, thinking that he would not agree to the plan he proposed, and was about to speak, but Serena's voice came into his mind, "Teacher, I accept your suggestion, please use illusion to sharpen my mind." ”

Orochimaru looked at Serena with a complicated face, although he proposed this plan, but he was not ready to implement it, although using illusion is the fastest way to improve his mind, but he just figured out guò illusion to lead him to another safer way to improve his mind, but he didn't expect Serena to directly choose this way of illusion.

"Serena, have you really decided to hone your mind in this way?"

Serena said firmly: "Yes, teacher. ”

Orochimaru looked at Serena's determined eyes with a rare, heartfelt smile. "Serena, let me see how much potential you have."

Orochimaru: "Now that you've decided, let's get started, but before we start, I want you to remember one sentence, which is to believe in your own strength and don't give up lightly." ”

"I see, teacher."

"Ninja: Narakumi's Technique・Change!" After Orochimaru activated the illusion, Serena's gaze instantly became glazed.

"Serena, Narakumi's technique was originally an illusion to present the impression of your own heart and strike your heart, but in order to improve your mind more effectively, I imprinted all the ninjas I met into your mind, and they will keep attacking you until you fall, the only benefit of this technique for you is that there is no limit to cultivation, where you can

"Is this the illusion space? How will I hone my mind? Teacher. ”

"Whoosh!" A shuriken struck Serena, who quickly dodged when he saw this, and three figures appeared in front of him. "I see, is it fighting against the enemy in the illusion? Interesting, then I'm on, Iron Fist of the Fire Dragon! Serena struck at the three figures that suddenly appeared. It's just three shinobi, let me disappear. "Boom!" There was a loud bang, and the ground was destroyed by Serena's fist, and three figures were wiped out by his punch.

"Bump!" Just as Serena was secretly smug, a figure suddenly appeared and kicked him out, Serena got up from the ground and looked at the ninja who appeared in front of him in shock. "It's actually a middle ninja, teacher, don't take such a toying disciple, how can I fight."

The ninja on the opposite side didn't pay attention to Serena's complaints, and instantly came to him and kicked him again, Serena saw this and quickly dodged, fifty moves later, Serena found something wrong, although he was a C-level peak magician, but he had not yet reached the B level, it was impossible to fight with the middle ninja for so long without injury. "Could it be that I've been promoted to a B-rank magician, it's impossible." Serena quickly shook his head to shake off the unrealistic illusion, his eyes instantly brightened, since it was not a breakthrough, then there was only one possibility. "Isn't there a limit to cultivation here? In this way, it's okay, Thunder Flame Dragon Mode, Thunder Flame Dragon's roar! Spit out a pillar of flame that intersected with thunder and fire from Serena's mouth, instantly evaporating the ninja who was fighting him from the human world.

Serena looked at his hands excitedly, very excited, the Thunder Flame Dragon mode is a mode that can only be used by S-level magicians, that is, it is equivalent to a shadow-level powerhouse of the Hokage. The dragon slaying magic that can use two or more attributes at the same time can only be used if it reaches the S level, he obviously does not have such strength now, there is really no cultivation limit here, Serena raised his head to the sky excitedly and shouted: "Who else? ”

The illusion was filled with Serena's arrogant voice, but the arrogance lasted only three seconds, and hundreds of ninjas attacked Serena at the same time. "Haha! It's good to come here, let you see the power of dragon slaying magic, the mystery of dragon slayer: Red Lotus Explosion Thunder Blade! "My hands flashed with lightning and flames, my body spun around, and I used a 360-degree indiscriminate attack on the surroundings, and one after another thunder blades shot in all directions.

Serena was very satisfied with the effect of the Red Lotus Explosion Thunder Blade, and he was surrounded by corpses, all of which had died under the move just now, and the corpses were scorched by the flames and had been unrecognizable. However, looking at the ninjas gathered around him again, Serena smiled bitterly. "There are so many!"

Serena reluctantly engaged in a protracted battle with the ninjas, although the illusion was not limited to cultivation, but there was a limit to the spirit. Three days later, Serena's vision had begun to blur and his attacks were becoming more and more weak, but he did not fall lightly, because as long as he fell here, he would lose a qiē. An hour later, Serena finally knocked out the last ninja, and he fell to his knees, gasping for air. "It's finally over, isn't it over now?"

"Is that all you have?" Serena was shocked when he heard the voice, he had been fighting for three days, and no ninja in the illusion had spoken, and when he looked up, he was even more shocked.

"Sansho fish Hanzo!" At this time, Serena couldn't help but complain in his heart: "Teacher, even if you want to exercise my mind, you don't need to get this big boss out." ”

"If you only have this kind of Cheng dù, just die here, a flash!" The scythe in Hanzo's hand instantly slashed at Serena's chest, and Serena wanted to dodge, but Hanzo made a move too fast for him to dodge at all.

"Whew!" Blood spurted from Serena's chest in an instant, and he was killed by Hanzo with a single sword, and fell in a pool of blood. Serena tried to get up, but found that his body was getting heavier and heavier. "Is this what death feels like? Am I failing? Sanshoyu Hanzo, I really can't defeat it? ”

"Serena, we have agreed, you will protect Konoha instead of me."

"Don't worry, Father, I will definitely protect Konoha and let my name resound throughout the five countries."

"Then we'll make an agreement, Serena."

"Hmm!"

"This is my agreement with my father, what are you kidding? My promise has not been fulfilled yet, how can it be possible to fall here. Serena struggled to get up from the ground.

Sanshoyu Hanzo: "Oh, I can still get up if I am stabbed, yes, then take me another knife." ”

Serena looked at Hanzo who was attacking him and shouted: "It's just a phantom, don't be too arrogant to me, Celestial Dragon mode, Celestial Dragon is roaring!" A pillar of colorful light shot out of Serena's mouth, directly smashing Hanzo into nothingness, shattering the entire illusion space along with it.

Outside, Orochimaru looked at the disciple in front of him in shock and let out an incredible exclamation. Serena was still the same, but a huge golden aura appeared on his back, and on top of the aura were eight special dragon-shaped phantoms, arranged in four corners and pointing in all directions. "Is this the true gesture of the Serena bloodline? It's shocking, and I'm so lucky to be able to teach him. ”

The aura dissipated, and Serena woke up from her vision. "Teacher, I succeeded." Then he fainted,

Orochimaru looked at Serena who had fainted and smiled with relief. "Serena, I was not mistaken, but you still have a long way to go before you get to the state you just had."

Orochimaru looked at the dark sky, and then at Serena, who had fainted, and said helplessly: "It seems that I am going to sleep here today, and I knew that Serena would not have burned down the house, so that there is a place to sleep." Orochimaru lit a bonfire and sat on the ground ready to survive the night.
