Far from the training grounds outside the village, Uchiha Fucheng and Mikoto arrived beside a dammed lake.
The dammed lake, formed by floodwaters blocked by soil, was gathered in a small valley.
Neither of them was wearing Ninja attire; Uchiha Fucheng and Mikoto looked more like a young couple out for a weekend excursion.
"Let's do it here."
Uchiha Fucheng pointed at the lake surface.
"We will first test the manipulation of three types of energy: electricity, magnetism, and waves."
Uchiha Fucheng stood to one side and first handed Mikoto a steel rod bent into a spring.
Mikoto nodded and gripped both ends of the spring steel rod with her hands.
Without any visible exertion, a scorching, bright red glow appeared at the center of the spring steel rod.
Uchiha Fucheng commented, "The current intensity is very strong, comparable to the destructive power of an S-rank Lightning Release."
Next, Mikoto dropped the glowing red steel rod and pulled two specially made Kunai from her pocket.
Mikoto held the Kunai flat in her hands, letting the two metal Kunai hover nimbly above their heads like drones.
The magnetic control was like being pulled by transparent Chakra threads.
"Launch!"
Mikoto waved both hands, and the two Kunai shot out at high speed.
Just as if they had been flung by her arms, they flew straight from the shore toward the center of the lake.
Thirty meters, fifty meters, eighty meters...
Throwing with magnetic force reached double the distance compared to Mikoto's usual method of throwing accelerated by Lightning Release.
The attack power was also significantly greater than throwing with her arms.
Uchiha Fucheng nodded, "Your magnetic control is very similar to the Third Kazekage from the Sand Ninja, it has a bit of the flair of the Magnet Release bloodline."
Mikoto looked happily at the Kunai flying toward the opposite shore of the lake, feeling extremely excited.
"I've tested electricity and magnetism, but what about waves? What method should I use to test this?"
Uchiha Fucheng smiled, "Don't worry. Do you remember what I told you?
Waves have different propagation rules in the air compared to conductive objects.
This time, we will use vibration to test the transmission of waves.
In a moment, I will take this thin metal sheet and move more than a hundred meters away from you.
You try to transmit waves to my metal sheet; if the energy and frequency of the waves meet the conditions, it can trigger the vibration of the metal sheet."
After speaking, Uchiha Fucheng used the Body Flicker Technique to move away from Mikoto.
He stood at the other end of the dammed lake before letting Mikoto begin the test.
At first, Mikoto's attempts were not successful.
Eventually, by coordinating her gestures and the angle of her arms, she managed to make the metal sheet in Uchiha Fucheng's hand vibrate slightly.
"It worked!" Mikoto cheered.
Uchiha Fucheng returned to Mikoto's side and continued to explain.
"Let's test the wave detection capability. I just placed three humanoid targets on the other side of the lake. Close your eyes and try to emit short, dense waveforms, then rely on the reflection and refraction feedback of the waves to determine the specific locations of the humanoid targets."
Mikoto nodded and closed her eyes, facing the lake.
She stretched out her arms, forming a "big" shape, and jumping electric sparks of a dozen centimeters appeared on her body.
Zzzzt~
Crackle~
An invisible electromagnetic wave quickly spread out from the position where Mikoto was standing.
As the electromagnetic waves collided with different objects, they returned to Mikoto.
"I think I can feel it, but the detection distance cannot be too far."
This type of attempt seemed to put immense pressure on Mikoto's body.
After three minutes, Mikoto opened her eyes, her face covered in sweat.
"Uchiha Fucheng, I can discover the humanoid targets on the opposite shore of the lake, and even behind some rocks and trees, I can clearly detect the size and position of items as if I were seeing them.
But my maximum detection distance is only about five or six hundred meters. The larger the range, the more feedback I get, and it becomes more chaotic.
All kinds of wave information make my head hurt whenever I think back to it." Mikoto gently rubbed her forehead, looking a bit dizzy.
Uchiha Fucheng wiped the sweat from Mikoto's forehead and said affectionately, "It must be that the range of the waves is too large. When you release electromagnetic waves with yourself as the center, for every additional meter of distance, the scanning area of the electromagnetic waves increases geometrically.
In the future, we must find a way to let you control the propagation direction and the spread angle of the waves.
Only letting the electromagnetic waves scan a very small angle should be able to reduce the pressure on your body."
While lowering her head to wipe her sweat, Mikoto pinched Uchiha Fucheng's palm hard, then imperceptibly swept her eyes toward their left side.
Uchiha Fucheng became alert immediately!
He understood that Mikoto was trying to convey the message that "there are enemies nearby."
It seemed that the electromagnetic wave scan just now had allowed Mikoto to discover unusual enemies.
The two pretended that nothing had happened and continued to chat.
Uchiha Fucheng simply arranged to test the Railgun they were about to try.
"Mikoto, take this custom coin, first extend your right arm, then imagine electromagnetic force building one magnetic ring after another in the direction of your right arm.
The slender channel built by these magnetic rings will extend straight in the direction of your attack.
After the magnetic channel is built, you can flick the coin with your thumb, use the magnetic rings to accelerate the coin in sequence, and let it accelerate to the fastest speed it can reach."
While explaining, Uchiha Fucheng helped Mikoto position her arm.
Mikoto first tested a low-energy-level Railgun attack using less electricity and magnetism.
Crackle; as the electric light flashed, the coin followed Mikoto's flick, blasting a twenty-meter-long concave wave on the lake surface.
A large spray of water splashed up, refracting brilliant seven-colored light under the sun.
"It worked!"
Mikoto looked happily at Uchiha Fucheng, and when she specifically turned around, she mouthed the words "He is still there."
Uchiha Fucheng held Mikoto's palm and gently slid his finger.
He directly wrote the word "Ambush" on Mikoto's palm.
Seeing Mikoto's expression indicate understanding, Uchiha Fucheng nodded affirmatively and continued to say loudly, "Then this time, use your maximum energy output to test what level of power it can reach under high-power conditions."
Still facing the lake, Mikoto extended her right hand flat, with an identical coin held in her hand.
Crackle.
Turning on the electromagnetic force once again, it was as if an invisible electromagnetic acceleration rail had been set up on Mikoto's arm.
In an instant, Mikoto's arm suddenly turned in place!
The Railgun turned directly from the direction facing the lake to the position where she had just discovered the unknown enemy.
The Railgun coin, without any delay, shot out at high speed, carrying huge electric light.
From the position where Mikoto was standing, the coin shot straight toward a thick, sturdy tree that would take two people to wrap their arms around.
A huge circular gap exploded on the left side of the tree.
A piece of white debris mixed with soil and a large cloud of smoke rising into the air exploded from behind the tree.
The roar of this Railgun was even much slower than the speed at which the explosion appeared.
Uchiha Fucheng laughed heartily, appearing at the explosion site with a Body Flicker Technique.
Loud laughter came from afar.
In the gradually dispersing smoke and dust, Mikoto saw Uchiha Fucheng, who had run over, happily waving at her while holding a white humanoid creature whose upper body was barely intact.
"What is this?"
Mikoto looked at this mysterious humanoid creature and felt a bit of scalp numbness.
Uchiha Fucheng looked at the half-body in his hand and discovered that he actually knew the exact identity of this thing.
"This is a type of biological clone called White Zetsu."
Looking at the lower body of the White Zetsu that had been blown to pieces by Mikoto, Uchiha Fucheng was a bit curious.
He even used his hand to tear off a piece of the White Zetsu's body tissue.
He squeezed it in his hand to feel it and discovered that the White Zetsu's flesh and blood did not resemble biological limbs at all.
Uchiha Fucheng analyzed, "There is no blood, nor the softness of human tissue; this feels more like a flexible vine when squeezed."
Uchiha Fucheng walked up to Mikoto, and he also discovered another magical thing.
The White Zetsu, which only had half a body left, could actually twist its arm to resist.
The White Zetsu could originally speak, but as Uchiha Fucheng approached Mikoto, this half-bodied White Zetsu seemed to have become a completely unconscious clone shell!
A system prompt then appeared in Uchiha Fucheng's mind.
"Do you want to assimilate the clone: Misaka Network construction."
