Two months passed in a blink of an eye.
The underground training ground of the Senju mansion has long been transformed beyond recognition by Senju Chen.
The walls are covered with traces of various Ninjutsu bombardments, the ground is pitted, and the air is filled with a peculiar smell of Chakra mixed with scorched earth all year round.
In the past two months, Senju Chen has spent almost all his time here.
In addition to occasionally visiting the "Food Is Heaven" head office to deal with personnel and branch opening matters, he was like a madman obsessed with research, constantly repeating the process of creation, testing, and destruction.
"Huh..."
Senju Chen let out a long breath and looked at the "masterpiece" in front of him. Even if it was himself, there was a hint of shock and enthusiasm in his eyes.
In the center of the training ground, a clone stood quietly.
From the appearance, there is no difference between it and Senju Chen, even its breath is perfectly imitated.
But if you use Sensory Ninjutsu to probe, you will find how complex and terrifying the Chakra contained in its body is.
The five hearts, like five engines with different attributes, are beating steadily in its body, continuously providing power through the black Earth Grudge Fear meridians all over the body.
The cells of Wood Release Cells and Tailed Beast are perfectly integrated, giving it vitality and resilience far beyond those of ordinary ninjas.
This is the final result of Senju Chen in two months - five hearts and one body, Earth Grudge Fear Wood Release Clone.
"Tsk... In order to create a thing like you, I took the heart inventory from the teacher, but I almost used it up." Senju Chen couldn't help complaining in his heart.
In the past two months, he had scrapped more than thirty experimental subjects, and consumed more than fifty hearts.
In other words, his family has a strong foundation, and no ninja would be able to withstand such a torment.
"But it's all worth it."
Senju Chen's mouth curved, and he gave instructions to the clone in front of him.
"Go ahead and let me see where your limits are."
The clone's eyes flashed red, and without any hesitation, his hands instantly Hand Seals.
"Fire Release·The Art of the Fire Dragon!"
A huge fire dragon composed of blazing flames roared out. The dragon's head was ferocious, and the heat wave was rolling, almost igniting the air in the entire underground training ground.
"Wind Release·Great Breakthrough!"
The body of Senju Chen is also Hand Seals. The strong wind roared out and collided heavily with the fire dragon.
"Boom--"
The wind assisted the fire. With the blessing of the strong wind, the size of the flame dragon more than doubled, and its power became even more terrifying.
Senju Chen put his foot down, retreated violently, and at the same time Hand Seals his hands again.
"Earth Release·Earth-Style Wall!"
A thick earth wall rose from the ground to block him.
The flame dragon slammed into the earth wall, making a deafening noise, Tsuchiishi flew away, and the wall was instantly covered with spiderweb-like cracks.
"The power is pretty good." A hint of appreciation flashed in Senju Chen's eyes.
The power of Fire Release used by this clone is no less powerful than Elite Jonin of the Uchiha Clan.
And this is just the beginning.
The clone on the opposite side was unable to hit a single hit, and the attack changed again.
"Lightning Release·Lightning Spear!"
A thick lightning spear spurted out from its mouth, with an ear-piercing scream, instantly penetrated the crumbling earth wall and stabbed Senju Chen straight into the chest.
"Water Release·Water Formation Wall!"
Senju Chen reacted extremely quickly, and a circular wall of water appeared out of thin air, firmly protecting him within it.
"Chi chi chi--"
Lightning Spear hit the water wall, stirring up a large amount of water vapor, and electric current spread in the water, turning the entire water wall into a lightning cage.
"It's not over yet!"
The cloned figure, Flying Thunder God, appeared on the side of Senju Chen. Its arms were covered with a thin layer of Tailed Beast Chakra Cloak, and its five fingers formed claws, grabbing hard.
The speed was so fast that it even left a faint afterimage in the air.
"Has Taijutsu also been strengthened to this point..." Senju Chen was slightly startled, and Chakra Burst stepped on his feet, narrowly avoiding the blow.
The clone's sharp claws grazed the corners of his clothes, leaving five deep claw marks on the ground.
"Tsk, this attack strength is okay."
Senju Chen looked at the claw marks and couldn't help but smacked his lips.
This clone is simply a mobile Ninjutsu turret, and it has incredible melee capabilities.
Ninjutsu with five attributes is at your fingertips, and combined with Taijutsu blessed by Tailed Beast Chakra, an ordinary ninja would be instantly killed if he encountered it.
"Come again!" Senju Chen is full of fighting spirit.
He wanted to see how long this clone could last in a high-intensity battle.
In the next hour, the entire underground training ground turned into a sea of Ninjutsu.
Fireball, wind blade, Lightning Spear, Earth Spear, water dragon...Ninjutsu with various attributes were released by the clone without any gaps, as if its Chakra would never be exhausted.
Even Wood Release, Flying Thunder God, Rasengan... all kinds of unique skills at the bottom of the box are taking turns.
For a moment, the roaring sound was endless, and the ground of the entire Senju mansion was shaking slightly.
Finally, after a confrontation between "Rasengan" and "Composite Ninjutsu", the clone's movements showed a moment of lag.
Senju Chen keenly captured this change.
He looked closely and saw tiny cracks beginning to appear on the surface of the clone's skin, like dry land.
Wisps of Chakra are escaping uncontrollably from those cracks.
"Have you reached your limit?" Senju Chen knew clearly.
A high-intensity battle lasts about an hour, which translates into a normal battle rhythm, which is almost a day.
And if it is in standby mode, without fierce fighting, the five hearts and Earth Grudge Fear tentacles in the body can absorb Natural Energy on their own, barely maintaining a balance, and can last for about three days.
"Although it's still a bit short, it's enough for normal combat." Senju Chen nodded with satisfaction.
This result has exceeded his expectations.
He stopped attacking and looked at the clone opposite him quietly.
Without the Senju Chen pressure, the Chakra conflict within the body becomes more intense.
There were more and more cracks on its body, getting bigger and bigger. Finally, with a "bang", the entire body turned into a pile of dead wood and black tentacles, scattered on the ground.
Senju Chen walked forward, squatted down, and picked up a withered black tentacle.
"If you want to extend the duration, you must solve the problem from the root." He murmured to himself, "Either improve Earth Grudge Fear to make it more perfectly integrated with Wood Release Cells; or optimize the Tailed Beast cells to eliminate the violent consciousness and only retain pure life energy."
Neither of these two studies could be completed by him alone.
"The stock of heart and Tailed Beast cells is almost at its bottom." He said with a pained look on his face, "This thing is simply a bottomless pit."
"It seems it's time to find Teacher Orochimaru."
Senju Chen stood up and dusted off his hands.
Not only for technical difficulties, but more importantly...
"You can't go to the teacher empty-handed every time." He touched his chin, a glimmer of light flashed in his eyes, "The results of this research should interest the teacher... Just think of it as the 'expense' for supplementing experimental materials."
