The undead, previously charging forward with abandon below the city wall, vanished instantly. These undead were propelled three hundred meters away by the surging mud river of the Earth Flow Great River, piled up like garbage into a colossal landfill by a bulldozer. Their interlocked bone-limbs, unable to control themselves, became stuck during the rolling, your arm piercing my chest, my ribs inserting into your eye socket, creating a mess even more chaotic than a ball of yarn played with by cats, leaving everyone unable to move.
This was truly an unexpected delight!!!
But in the next moment, Li Xi was no longer delighted, because after pushing away one layer of undead, what was revealed beneath was still more undead, still burning with soul fire, still charging forward.
The same soul strength, the same bone density, the same skeletal structure, the same attack patterns, the same tireless nature, the same fearlessness in the face of enemies.
"I refuse to believe I can't clear them out, layer by layer," this was Li Xi's true inner thought; he was enraged.
"Earth Style: Earth Flow Great River"
"Earth Style: Swamp of the Underworld"
"Earth Style: Heavenly Canopy"
"Water Style: Exploding Water Wave"
"Fire Style: Great Fireball Technique"
"Fire Style: Ash Pile Burning"
.............
The surging mud river pushed the undead far away; the swamp covering several hundred square meters drowned countless undead; the giant lucky cat lid covered a vast area, its tonnage crushing undead into powder like a millstone...........
The large-scale Earth Style ninjutsu in Li Xi's hands seemed like cheap towels from a wholesale store, buy one get half free. After one ninjutsu, Li Xi didn't even know how many undead he had killed or how many were controlled. The suddenly flying soul fires were like fireflies in a summer forest, far more numerous than the stars in the sky.
"So strong."
Haisewei's eyes widened. How could anyone in this world wield magic so powerfully? His individual output could rival a platoon of mages. Certain laws within the dragon's inheritance seemed to be mocked and broken by Li Xi at this moment.
Even Humei, who was chanting spells with complete focus, couldn't help but slow down a beat upon sensing Li Xi's furious output. So, his magic could truly be instant!!!
This near-death experience was worth it!!!
After unleashing dozens of powerful, large-scale ninjutsu, even after the Chakra of his shadow clone form was depleted and he disappeared, Li Xi tirelessly created ten shadow clones multiple times to ensure his side's firepower continued to bombard relentlessly.
Countless undead were pushed far away and trapped by the Earth Flow Great River, unable to move; countless undead were drowned by the Swamp of the Underworld and sunk into the layer of bones; countless undead were crushed and sealed beneath the Heavenly Canopy, unable to move; countless undead were burned to ashes by the Great Fireball Technique, scattering in the wind; countless undead were blown into powder by the Ash Pile Burning, like the mist of an autumn morning; and the Water Style, which had little effect and was not used a second time.
But when Li Xi's ninjutsu ended, countless undead still crawled out of the swamps, from beneath the Heavenly Canopy, from the piled-up mountains of undead garbage, from the high temperatures after the flames had burned, and continued their attack without a care.
Li Xi finally understood what "vast ocean" and "undead catastrophe" meant. There were simply too many. Like a thousand-layer cake, every layer was filled with undead, and no matter how many were killed, there was no end in sight.
Even the thick walls of the Earth Flow City Wall had been broken through three times and repaired by Li Xi at critical moments.
And less than half a sandglass of time had passed. Li Xi calculated that one sandglass was about fifteen minutes, and Humei needed two sandglasses, which was thirty minutes. At the current intensity, Li Xi was confident he could handle it. As long as his Chakra didn't run out, no amount of undead could reach Humei's eyes. But were there only undead below Level Six in this vast undead plane?
After repelling another layer of undead, the newly appearing undead unit informed the outsider what they should face next.
Their limbs burned with pale white undead flames, and atop their robust skeletons sat knights clad in bone armor, wielding undead lances nearly three meters long. The soul fire behind their bone masks was more potent than any undead seen before. The mounts beneath them impatiently pawed the ground, easily shattering the undead beneath their feet into pieces.
These were the main ground combat units of the undead army, chosen from outstanding cavalry and mounts of various races throughout history. Each of them had achieved commendable feats in life and retained their unyielding charge in death. These were the Undead Knights, feared by countless people!
Their strength started at Level Five. In life, they were already excellent cavalry. In death, they were even more integrated with their mounts, meaning the strength of undead cavalry rarely declined. On the contrary, being fearless of injury and death, their fighting style was more extreme, and mutual destruction was a common occurrence, making them even more difficult to deal with than life-based cavalry of the same level.
Li Xi was exasperated. The undead knights before him were like cabbages in a greenhouse, coming in an endless stream from afar.
This wasn't one, two, ten, or a hundred. Li Xi estimated he saw at least ten thousand undead knights.
There were no ear-splitting war cries before battle, no majestic neighing. There was only silence, a dead stillness, without a sound except for the crunching of undead bones being crushed under the hooves of their mounts.
Even ten thousand people would form an endless expanse, let alone charging undead knights. All undead in front were knocked aside. One row of undead knights would spearhead the advance, and the undead knights behind would accelerate. The three-meter-long bone lances were truly lethal weapons. Before the enemy could even see them, the undead fell like leeks under a sickle, cut down in neat rows. Not a single undead remained standing on the ground after the charge of the undead knights.
In the main world, these ten thousand undead knights could conquer an entire barony!
If these undead knights reached their front, the Earth Flow City Wall would surely not withstand the continuous impact of tens of thousands of cavalry. After all, the Earth Flow City Wall was just a basic earth wall, not a stone wall built with bluestone, nor an enchanted wall of Isengard.
The undead were held back by this earth wall due to insufficient force, but it would be shattered before long. Now, facing the undead knights, Li Xi estimated that after two waves, the Earth Flow City Wall would be breached, and they would directly attack Humei.
Li Xi became resolute. If one Earth Flow City Wall was not enough, then ten!
"Matatabi, I'm starting," Li Xi's voice entered the sealed space.
The Two-Tails Matatabi and the Three-Tails Isobu were both observing the situation outside the seal with great concentration. In their previous world, they had never witnessed such a scene. The total number of participants in several Ninja World Wars combined was less than a tenth of the current number. Moreover, each undead here started at the level of a Chunin. Just the Jinchuriki, Li Xi, had repelled tens of thousands of undead, which was equivalent to repelling tens of thousands of Chunin. Yet, such a colossal number was like a drop in the ocean, a single strand in a thousand hairs, for the enemy. This world was too insane!!!
Matatabi's blue flames surged three feet high. "Go ahead and use it without worry. If that's not enough, there's still Sanbi."
Sanbi Isobu, in the sea beside him, nodded. He had only arrived in this world not long ago and had already encountered such a life-or-death battle for a Jinchuriki. How pitiful! May the Jinchuriki not die. He hadn't enjoyed the sights of this other world enough yet. He quickly said, "Yes, with both of us here, use your Chakra boldly. If it's not enough, transform into your Tailed Beast form."
"As long as Gajeel doesn't show up, we should be able to handle everything else. I'm going to act now."
Blue flames suddenly erupted from Li Xi's body. This was not caused by Matatabi's control, but by an excessive amount of Chakra, which had begun to overflow uncontrollably.
"Shadow Clone Technique"
"Bang bang bang"
A full fifty Shadow Clones appeared, all performing hand seals in unison and slapping the ground.
"Earth Style: Earth Flow City Wall" x51
It was as if the entire plane was trembling. The undead in front of Li Xi, both near and far, swayed as if drunk. Fifty-one wide walls rose from the ground, varying in height and distance, not forming a continuous layer of walls to protect Li Xi and the others.
Instead, they intersected, forming a complex labyrinth. This labyrinth was initially crude and full of loopholes, but immediately, Li Xi and his shadow clones used Earth Flow City Wall again.
"Earth Style: Earth Flow City Wall" x51
After three consecutive uses, the Chakra of the shadow clones was depleted, and they disappeared.
Even the uncontrolled blue overflow Chakra on Li Xi's body had vanished. Matatabi in the sealed space also breathed a sigh of relief; even the Chakra of the Tailed Beasts had its limits.
The effect of expending so much Chakra was evident. The labyrinth, covering an area the size of ten football fields, was finally complete. The paths were winding, intersecting, and convoluted. Even Li Xi, the creator, didn't know where the exits were.
As soon as the labyrinth was constructed, the undead knights, carrying boundless killing intent, charged into the maze. Li Xi smiled. As long as they didn't engage in a head-on confrontation, the advantage was theirs.
Here, one could see Li Xi's quick thinking. Their objective was to protect Humei while she used magic to burn through the spatial barrier, not to vanquish evil or create legends. Everything was for the sake of buying time and surviving.
If they had continued to protect themselves with successive walls, the subsequent battle would have been the ordinary undead and undead knights trying to break through the walls, which would have been no challenge for them. Hundreds of thousands of undead attacking simultaneously would have been enough for the walls. At that point, Li Xi would have been constantly busy repairing the breaches, a mere handyman putting out fires without solving the root cause.
But changing the walls to a labyrinth made a difference. As long as there was a path, the mindless undead would follow it. Whether they would end up going in circles or returning the way they came after a few laps was not Li Xi's concern. Since the undead had poor intelligence, it was only fair to exploit their stupidity.
"Earth Style: Heavenly Canopy"
Li Xi even thoughtfully placed lids on certain key positions of the labyrinth to prevent the undead from climbing over the walls.
After watching for a while, the labyrinth proved effective. The attacking undead were reduced by half. Ninety percent of the undead were disoriented within the maze, and the undead knights were also circling around. After a long period of charging, they hadn't seen a single living person, and the flickering of their soul fires had slowed down. They didn't understand why they were moving forward but never getting out.
Offense isn't always the best defense; infrastructure defense also yields good results.
However, as Li Xi rejoiced in how changing his strategy had lightened his burden, he was unaware that the massive tremors caused by his labyrinth construction had also attracted the enemy's attention.
In a certain part of the plane, amidst several mountains formed from piles of bones, on the highest mountain, a two-zhang-tall undead figure seated on a throne suddenly sensed something. The soul fire in its originally empty skull flared up with a 'poof'.
This colossal undead stood up. Its towering skeletal frame was covered in densely packed gray-white magical runes, indicating it was an undead that had been refined and then enchanted.
An invisible wave emanated from it, quickly locking onto the source of the vibration. It seemed to see the four people and one dragon struggling to survive, that magical labyrinth, and the massive undead army falling in swathes.
There was no sign of anger. It reached out and grasped, and a bone dragon lance ten meters long appeared in its hand. The same gray-white magical runes covered the entire lance.
The towering undead merely tapped its bone dragon lance heavily on the undead mountain beneath its feet. The entire mountain trembled slightly and then seemed to come alive.
The undead throne behind it moved instantly, and the towering undead sat back down. Where it had stood, an indescribably massive skull rose, and from the foot to the top of the mountain, countless small undead fell amidst the trembling. Three pairs of bone wings, capable of obscuring the sky, unfurled, their whistling winds capable of causing village-destroying disasters. The tail of a monstrous bone dragon, larger than two of Haisewei's bodies, swept away everything around it with a gentle flick. Its limbs, over ten meters high, and every part of its body were covered in a dense cluster of white crystal bone spurs. A soul fire larger than a house ignited. This mountain was actually a bone dragon over a hundred meters long!
A giant holding a bone dragon lance, combined with the hundred-meter-long dragon beneath it, the mere aura emanating from them caused the bones on the ground beneath the bone dragon to turn to ash.
If Haisewei, with her Level Six strength and twenty-three-meter body, were placed before the hundred-meter-long dragon, it would be like a wild dog standing at an elephant's foot, a go-kart driving in front of a truck, or a 1.2-meter-tall minor challenging a prime Tyson. It would simply be foolish and out of touch with reality.
