Simultaneous traversal: All Abyss difficulty.

Chapter 23: Third update, please support, the second ninjutsu! Senju Tobirama's jutsu? (Please give me a monthly ticket)
The sunlight shines through the treetops and onto a quiet waterfall outside Konoha Village. The water splashes and a rainbow hangs above it, creating a pleasant scenery.

Uchiha Yu stood under the waterfall, letting the cold water hit his body.

He was trying to control his chakra and learn the basics of water-style ninjutsu.

Amid the roar of the waterfall, Uchiha Yu formed seals with his hands, closed his eyes, and felt the power and rhythm of the water.

His Sharingan spun slowly beneath his closed eyelids, seeming to simulate the flow of water.

His palms began to glow with a faint blue light, and the connection between chakra and water was gradually established.

He tried to release chakra into the water flow, allowing his body to merge into one with the water flow.

On a tree not far away, Hatake Kakashi was lying leisurely on a thick branch.

He held a copy of "Intimate Paradise" in his hand, occasionally turning the pages, immersed in the world of the book.

His eyes would occasionally move away from the pages of the book and glance at Uchiha Yu under the waterfall, with a hint of admiration in his eyes.

Every time Uchiha Yu successfully guided the water flow, or failed in his attempt, Kakashi would nod slightly or sigh softly.

He did not intervene immediately, but gave Uchiha Yu enough space to explore and learn, and only gave appropriate guidance at critical moments.

As time went by, Uchiha Yu gradually mastered the essentials of water-style ninjutsu. His chakra control became more and more proficient, and the water flow he guided became more and more powerful.

Kakashi closed the "Intimate Paradise" in his hand, jumped lightly from the tree, and prepared to give Uchiha Yu further guidance.

"Not bad, Uchiha Yu, you've made faster progress than I expected."

There was a hint of laughter in Kakashi's voice, "Next, we can try some more complicated water ninjutsu."

"What is it?" Uchiha Yu was surprisingly excited!

Because this is the second ninjutsu he has learned seriously besides the Three Body Techniques!

Amid the roar of the waterfall, Kakashi stood with his hands behind his back, stepping lightly on the water, as if he was one with nature.

His voice was calm and profound, penetrating the sound of water and clearly reaching Uchiha Yu's ears: "Before you learn, you must first understand one thing."

His gaze penetrated the layers of mist and fell on Uchiha Yu.

"Water escape technique comes from the exquisite control of water attribute chakra." Kakashi's tone revealed a hint of seriousness, and he continued: "It is not just an offensive ninjutsu. Compared with fire escape technique, it is more often used as a defensive ninjutsu."

"Normally," Kakashi slowly paced on the water, the waves gently rippling under his feet, "Ninjas perform water jutsu by manipulating the surrounding water."

He waved his hands gently, as if drawing invisible spells in the air, and the surrounding water molecules seemed to respond to his call, forming tiny streams of water.

"However," Kakashi's voice was filled with a hint of reminiscence, "a truly outstanding water-style ninja can summon water forms with the power of chakra even in a waterless place."

"The Second-generation Hokage of Water Style without Water, Tobirama Senju?" Uchiha Yu gave the answer.

"Yes and no. The Second Hokage is the most famous representative among them. There are also the Second Mizukage and the Fourth Mizukage."

"But actually." Kakashi pointed at himself shamelessly, "I can do it too."

Uchiha Yu rolled his eyes, "Alright alright, I know you're awesome Kakashi-sensei, so which jutsu are you going to teach me?"

"Alright!"

As Kakashi's voice fell, his figure lightly touched the water surface, leaped backwards, and put some distance between him and Uchiha Yu.

His hands formed seals quickly at a speed that was almost impossible to catch!
Because the movements were too fast, Uchiha Yu didn't even see how many seals were made, and Kakashi's ninjutsu had already been completed!
After Kakashi completed the hand seal, a powerful chakra surged out of his body and rushed straight to the water surface under the waterfall.

The chakra seemed to have life, quickly merging with the water flow and stimulating an astonishing power.

The water surface began to fluctuate violently, as if being pulled by some invisible force, forming a huge wall of water. The wall of water rose rapidly, like a crystal barrier rising from the bottom of the lake to the sky, shining brightly in the sun.

The surface of the water wall is shimmering, but it is extremely solid, as if it can withstand any attack.

This is it! Water Style: Water Wall!
A B-rank defensive ninjutsu created by the second Hokage, Tobirama Senju! Famous for its powerful defensive capabilities and spectacular visual effects!
Uchiha Yu stood there, staring in amazement at the spectacular scene before him.

He didn't expect that Kakashi would teach him such an advanced ninjutsu right away.

The movement and visual effects of this ninjutsu far exceeded his expectations, allowing his understanding of water-style ninjutsu to reach a new level.

"Is this water-style ninjutsu?" There was a slight tremor in Uchiha Yu's voice, and his eyes were flashing with excitement and desire.

Kakashi stood on the other side of the water array wall, his figure looked even more mysterious and powerful against the backdrop of the water wall.

His voice passed through the water wall and reached Uchiha Yu's ears clearly: "Yes, this is the water wall. It can not only defend against physical attacks, but also resist some ninjutsu attacks. Come on, use your fireball."

Before Kakashi could finish his words, Uchiha Yu quickly formed seals with his hands!
"Art fire escape ho fireball!"

The huge fireball was like a burning comet, cutting through the air and crashing into the water array wall with a scorching trail.

The water wall rippled under the impact of the fireball, the collision of flame and water made a hissing sound, and water vapor spread out, forming a hazy mist!

However, despite the enormous power of the fireball, the water array wall was like an indestructible fortress, firmly blocking the attack.

The flames of the fireball dissipated on the water wall, turning into wisps of green smoke, but the water wall still stood firm.

Kakashi stood on the other side of the water array wall, a satisfied smile on his face.

The water-based defensive ninjutsu he performed was difficult to break through even for a ninja from the Uchiha clan who had been using the Great Fireball for years.

What's more, the caster is a child.

Just as Kakashi was about to continue his teaching, Uchiha Yu showed no intention of stopping.

He quickly formed seals with his hands again, three times in a row, each time accompanied by a low shout, and three fireballs hit the water array wall one after another.

"Art fire escape ho fireball!"

Every impact of the fireball made the ripples on the water array wall more violent and the water vapor thicker.

Kakashi's eyebrows raised slightly, he was surprised at Uchiha Yu's chakra control and the speed of ninjutsu release.

Under the fierce impact of three consecutive fireballs, the water array wall finally reached its limit.

The water wall collapsed with the last impact, turning into countless water droplets that splashed everywhere, flashing dazzling light in the sun.

Uchiha Yu looked at the collapsed water array wall and a smug smile appeared on his face.

However, before his smile could fully unfold, a figure suddenly appeared behind him like a ghost.

Kakashi pulled Uchiha Yu upside down, with a hint of blame in his voice: "Little brat, are you so harsh on your master?"

Uchiha Yu was hung upside down, his expression was a little awkward, but he still forced a smile: "No, no, no, Mr. Kakashi, I just want to test how many fireballs this technique can defend against."

"Defense against the huge fireball?" Kakashi narrowed his eyes and muttered to himself.

How on earth did that eyebrowless Genin manage to provoke this gifted child?

　Three more updates to ask for support, it's the end of the month, the monthly tickets will go bad if I keep them! Give Xiao Kele some!
