Having just been attacked by the explosive tags, the Jonin from the Earth Hill was initially just surveying the surroundings, but he unexpectedly discovered a flaw in the enemy's genjutsu.
He stood in place, carefully observing the ground in front of him. Under the cold moonlight, although the ground was very dim, with his Jonin-level eyesight, he could still see clearly. As he moved his arm, the illusion on the ground would react correspondingly, swaying along with his arm's movement. Though the changes were very subtle, with his Jonin-level skill, he could still detect it if observed carefully. Just this slight delay had already allowed the Jonin to see through the essence of the enemy's genjutsu.
"Captain! Did you find something?" a subordinate asked as he noticed his actions.
"Yes! I have basically figured out the secret of their genjutsu!"
"That's great! Then we can..."
Before he could express his joy, he was interrupted.
"Let's wait until I test it a bit more. It's too early to celebrate!"
As he spoke, the Jonin from the Earth Hill raised his head and looked at the bright moon in the sky.
"Is this the medium they used to cast the illusion?"
With his gesture, his two subordinates also looked up at the moon, appearing thoughtful. No fool could become a Jonin! With such an obvious hint, how could they not understand the principle behind the enemy's genjutsu?
"Is it a projection genjutsu using the moon?"
"Yes! It should be like this!"
"To be sure, we need to test it!"
While answering his subordinate's question, the Jonin didn't remain idle.
"Earth Release: Rock Iron Cannon!"
A mass of refined Earth chakra was spat out, transforming into a boulder the size of a table in midair and flew towards the moon.
"Indeed, it's not that easy!"
As the rock bullet flew dozens of meters and hit the moon, it only wobbled slightly before returning to its original form, as if nothing had happened. On the ground, the indistinguishable scenery of Konoha's night market started changing as if disturbed water, creating ripples throughout the base, occasionally revealing its original appearance, making the camp appear like a reflection on the water ruffled by the breeze.
As the ripples calmed down, the night market of Konoha once again shrouded the land.
"Daring enough to hide nearby, huh!"
Although he didn't break the enemy's genjutsu, which was a bit disappointing, it wasn't without gains. The slight change in the illusion had already allowed the well-prepared Jonin to locate Toshiro's hiding place. However, once the illusion returned to normal, they lost sight of the enemy again. But it didn't matter; if they could disrupt the illusion once, they could do it a second or third time.
"Ryuu! If you can't find the enemy's location again, you can slit your throat yourself!"
He was quite displeased with the sensory ninja. It had been a long time and they still hadn't found the enemy's true location, which was disappointing.
"Understood! I won't disappoint you, Captain!"
The sensory ninja named Ryuu felt immense pressure. Earlier, the surrounding chakra of the enemy severely interfered with his sensing abilities, making him lose track of the opponent. However, with that fleeting glimpse earlier, he regained some confidence in finding the enemy's hiding place.
His teammates didn't remain idle either, continuously firing rock iron cannons to disrupt the enemy's genjutsu. One part was to assist their companion in sensing the enemy's position, and the other was to remind their comrades to hold on longer. They were unaware that their comrades, under the pressure of the genjutsu and the Uchiha ninjas, had to turtle up by enclosing themselves in a large Earth Release barrier, hoping for a breakthrough on this side to come rescue them.
"This genjutsu is truly troublesome! Even after discovering the flaw, there's no way to dispel it! Damn it..."
The subordinate attacking the sky couldn't help but complain. Their captain discovered the flaw in the genjutsu through the explosion of the explosive tags, but the opponent was cunning enough to tamper with the medium casting the illusion, making it impossible to break the genjutsu all at once.
"Finally found you!"
Amidst the abnormal fluctuations of the illusion, they finally found the relocated Toshiro and surrounded him, appearing ready to engage.
"It seems this genjutsu has considerable issues! You guys found the flaw so easily!"
Toshiro, seeing the three opponents taking a stance, felt a bit helpless. He still needed to maintain the barrier, making it unsuitable for intense combat. If he remained still and kept casting the illusion, it would be fine, but in a fierce fight, the barrier couldn't be maintained. Moreover, he hadn't expected such an obvious flaw in the genjutsu developed by himself, discovered due to the explosion of an explosive tag disturbing the nearby chakra. The genjutsu he developed had great practical value. By using his chakra to create a light source similar to the moon, he projected a prepared illusion onto the barrier.
To make the genjutsu more realistic, he incorporated some tactile illusion and chakra disguise, making the illusion almost indistinguishable from reality. He also applied some deceptive genjutsu to hide the secret of his genjutsu from opponents. He didn't expect one explosive tag would disrupt the chakra nearby, allowing the opponent to see through the genjutsu. Furthermore, without his teammates' cover, such a fleeting flaw wouldn't have been easily noticed.
For instance, in another battlefield, the Iwa ninjas under Tetsu's pressure could only defend passively, without time to observe their surroundings.
