The same phase can be accumulated repeatedly!
Haruto Saito immediately retrieved the Yin God Kunai from his item space, bit down on it, and formed hand seals again!
"Summoning Jutsu: Sleeper - Volcano!"
Boom! Boom! Boom!
Thick red mist exploded outward, rapidly taking shape and solidifying into four brand-new red energy giants!
Now there were twelve! Three sets of twelve! All of them at the elite jonin level!
It really could stack!
Different phases could not coexist. For example, if Haruto first used the first phase and then activated the second, the first phase would disappear. If he then activated the third, the second phase would vanish.
But if Haruto continuously summoned only the same phase, then the previously summoned entities would not disappear and could exist simultaneously!
This was insane!
This technique was absolutely broken!
And it was only a C-rank mutation!
"Stop!" Haruto commanded in a low voice.
The twelve energy giants, resembling miniature versions of Susanoo, all halted. Since they were massive—nearly three stories tall—it looked as if Haruto was surrounded by a cluster of towering buildings!
"Break!"
Boom! Boom! Boom! Boom! Boom! Boom!
All the red energy giants exploded, transforming into a red mist that rushed back toward Haruto. His chakra rapidly recovered—this was chakra replenishment. Actively dismissing these summoned beings allowed him to regain a portion of his expended chakra.
In the end, Haruto had recovered about 50% of his chakra!
Compared to the cost, the replenishment wasn't insignificant!
Haruto then took out his Mana Recovery Cards and consumed dozens of low-grade ones, fully restoring his chakra!
Immediately, he formed more hand seals—rapidly and continuously!
"Summoning Jutsu: Sleeper - Ashes!"
"Summoning Jutsu: Sleeper - Ashes!"
"Summoning Jutsu: Sleeper - Ashes!"
"Summoning Jutsu: Sleeper - Ashes!"
The mist completely engulfed the valley, radiating waves of powerful chakra. As the white mist cleared, the valley was filled with skeletal warriors! At a glance, they seemed like an endless army of ghastly apparitions!
Haruto had already formed seals thirty-four times, performing the summoning jutsu thirty-four times!
Now, surrounding him, were a total of 5,100 skeleton soldiers!
These skeleton warriors, clad in tattered armor and wielding broken weapons, all possessed the strength of genin-level shinobi! It was an army, and a formidable one at that! When numbers reached a certain level, quantity could transform into quality!
Although this skeletal army couldn't compare to a normal small military force and certainly couldn't threaten top-tier powerhouses like Haruto himself, they could still be incredibly useful in specific scenarios.
Sometimes, an army with weaker individuals but greater numbers was more effective than an elite unit with fewer but stronger soldiers!
And the most terrifying part—Haruto wasn't limited to summoning just thirty-four times! There was no upper limit! As long as he had enough Mana Recovery Cards or someone supplying him with infinite chakra, he could keep summoning indefinitely...
In truth, Haruto didn't know if there was a summoning limit, and he wasn't in the mood to waste time testing it for now.
After using the first phase thirty-four times, his chakra was nearly depleted.
But he still wanted to test more!
He actively dispersed all the skeleton soldiers!
Chakra replenishment!
Then, Haruto consumed more cards to restore his chakra completely.
Once more, he formed hand seals!
"Summoning Jutsu: Sleeper - Magma!"
"Summoning Jutsu: Sleeper - Magma!"
"Summoning Jutsu: Sleeper - Magma!"
"Summoning Jutsu: Sleeper - Magma!"
The white mist once again filled the valley. As it dissipated, over four hundred gigantic shield warriors emerged—also known as blade-shield soldiers! Each of them possessed the strength of elite chunin and specialized in defense!
Haruto summoned twelve times in a row, exhausting his chakra once again!
In total, he had summoned 460 shield warriors!
Terrifying!
Absolutely terrifying!
These four hundred plus shield warriors were enough to stall any enemy Haruto might face in the ninja world! Even the likes of Hiruzen Sarutobi wouldn't be able to eliminate over four hundred elite defensive chunin in an instant!
Between these shield warriors and the five thousand skeleton soldiers, which was stronger? It was hard to say!
If it was a battle of attrition, the shield warriors might fall first. But since they specialized in defense, whether or not the skeleton soldiers could break through their defenses was uncertain. How many attacks it would take to break through was also unclear… Haruto couldn't test it now, as shield warriors and skeleton soldiers couldn't coexist.
They simply had different uses!
For protection, shield warriors were the better choice. For sowing chaos, disrupting enemy formations, or engaging in a massive brawl, the five thousand skeleton soldiers were more suitable.
Against top-tier fighters, however, the skeleton soldiers would be massacred—too slow, too clumsy, and susceptible to wide-range attacks. The shield warriors, on the other hand… they could at least pose a challenge!
Haruto was exhilarated!
This unconventional C-rank, seven-star mutated summoning jutsu was absolutely incredible!
With a single gesture, he dismissed all the shield warriors.
The valley became eerily empty again.
Haruto then sat cross-legged, opened the Elemental Furnace, and retrieved a pile of junk cards from his item space…
He had to fuse another mutation card!
That evening, in the eastern coastal region of the Land of Fire…
Deep within the forest.
Two mysterious Mist ninja concealed themselves within the cool tree canopy—one stocky, the other thin. The stockier one was holding a black seabird in his arms.
"Caw!" A bird's cry suddenly echoed from high above.
The black seabird struggled slightly.
The stocky ninja released his grip, allowing the black seabird to take flight, soaring toward the sky. High above, an ordinary white bird was flying swiftly. The black seabird accelerated, and within a few breaths, it had caught up to the white bird, its sharp talons clutching onto the smaller bird's back before swooping downward!
This white bird was just an ordinary carrier pigeon—widely used for intelligence transmission by major ninja villages and mundane organizations. Generally, these birds were used for short-distance communications, though sometimes they carried long-distance messages.
The black seabird, however, was a specially trained attack bird from Amegakure, specifically bred to capture message birds!
The black bird landed back in the tree canopy with the white bird, which shrieked in agony.
"Check—does it have a message?"
"Yes, yes, there's a note on its leg!"
"Don't tell me it's just more intel about the pirates from Wave Island."
"We've been out here for a month. If we don't intercept something important soon, the captain is going to lose it!"
The two ninjas muttered as the stocky one held the white bird in place. The thin ninja untied the note from the bird's leg and opened it.
—Inform Haruto Saito to return to Konoha immediately and temporarily abandon the mission to develop Gutian Village!
