"Wang Luo, do you think there are other levels above Legendary?" Zhao Qingxuan asked worriedly.
"I'm not sure about that!" Wang Luo shook his head. The highest level of zombies he had seen in his previous life was Legendary, and he had never encountered any above that. Moreover, once awakened individuals reached the Legendary level, energy source crystals seemed to no longer have any effect on them. Everyone was curious about this at the time. No matter how many energy source crystals the awakened individuals absorbed, they couldn't advance to the next level. However, some speculated that to advance, one had to enter the underground world through the mist rifts, which led many people to venture below. Of course, it was also possible that advancing beyond the Legendary level required some special method that humanity had not yet mastered! But if there truly were levels beyond Legendary, Wang Luo was determined to explore them in this life.
A large number of low-level zombies poured into the crater, yielding countless Legendary-level zombies, which drastically increased the pressure on all the awakened individuals in the base.
"Let's stick to the previous method and let some people advance their levels first!" Zhao Qingxuan immediately made arrangements. This applied not only to humans but also to mutated beasts. A portion of the strong individuals would guard outside the city walls, while the remaining portion would use the harvested energy source crystals to advance. Only in this way could they withstand the zombie onslaught.
The order was carried out immediately. Many awakened individuals retreated from the battlefield and began to advance their levels on the city walls. It was extremely difficult for King-level individuals to contend with Legendary-level zombies. Except for those who had comprehended SSS-grade alien techniques and possessed SSS-grade awakened abilities, others stood no chance. However, once they advanced to the Epic level, things would become much easier. In fact, some awakened individuals had already reached the Epic level.
The zombies also noticed this. They knew very well that once the humans' levels increased, they would never have another chance to breach the base! Therefore, as soon as the Legendary-level zombies emerged from the crater, they joined the siege. Every strike from a Legendary-level zombie possessed unfathomable power, capable of incinerating mountains and cleaving peaks! Terrifying alien techniques clashed against each other, erupting with ocean-like energy. Multicolored lights dominated the sky, and the ground was littered with zombie limbs and remains. The area outside the city walls was like a descent into purgatory...
Because some people had retreated to absorb energy source crystals, the battlefield outside the city walls became even more perilous, and awakened individuals began to fall. This was something that always happened after each zombie evolution, and this time, they were all Legendary-level zombies.
Wang Luo re-entered the battlefield. He had already absorbed enough energy source crystals to advance to the Epic level, so this kind of battlefield no longer posed a threat to him. The Black Abyss swept across, and Wang Luo mowed down enemies! After advancing to the Epic level, even S-grade wind disasters could annihilate Legendary-level bosses, and in large numbers. The zombies paid close attention to every awakened individual capable of slaying Legendary-level zombies, immediately dispatching large numbers of Legendary-level zombies to encircle and suppress them. Yue Bai and King Ma were both injured in the encirclement by Legendary-level zombies.
Roar! Seeing the vast number of zombies appear, Wang Luo did not hesitate and unleashed his Dragon Transformation. In an instant, a colossal beast thousands of meters long materialized in the sky.
"Holy crap, what is that thing?" Many awakened individuals who had never seen the Azure Dragon form were terrified. The behemoth suspended in mid-air possessed an even greater oppressive aura than the Titan zombies! The Azure Dragon plunged from the heavens, its massive azure scaled claws tearing into the zombies, instantly killing over a dozen Legendary-level zombies. Its thick and powerful tail swung, and more zombies perished. In its Azure Dragon form, every strike inflicted heavy casualties upon the zombies!
Near the crater, several zombie bosses gazed at the Azure Dragon with dim eyes.
[It's not the legendary Azure Dragon!] one of the zombies growled.
[Indeed not. Legend has it that the Azure Dragon was a congenital deity, born as a divine being of calamity. This one is merely Epic-level, not even a pseudo-god, let alone a congenital deity!] The zombies confirmed that this Azure Dragon was not the one recorded as being suppressed by their ancestral god. Otherwise, they would have mobilized for a major conflict!
[Although its appearance is similar and its attack power is formidable, it's likely just some human alien technique. It doesn't possess the Azure Dragon's abilities, nor its divinity!] They detected no divine aura from the Azure Dragon, which relieved them.
[Continue to surround and attack it. Even if it's not that Azure Dragon, it will perish here today!] a zombie boss commanded. Instantly, a large horde of zombies charged forward, and countless terrifying attacks rained down upon the Azure Dragon's colossal body.
"Good coming!" the Azure Dragon's voice boomed.
"Wind Breath Tornado!" A massive torrent of dragon breath, laced with hurricane-force winds, erupted from Wang Luo's mouth. It resembled a giant horizontal tornado, spiraling towards the charging zombies.
Rumble!!! The power of the "Wind Tornado Dragon Breath" was immense. Wherever it passed, zombies turned to ash, and a gaping chasm was gouged into the ground! With a deafening roar, the opposite mountain peak in the distance was completely annihilated by the "Wind Tornado Dragon Breath"! Dust and debris flew, and when the dust settled, the summit of a mountain was utterly pulverized!
"A pity it's only an SS-grade alien technique! Otherwise, its power would be even greater!" Wang Luo sighed. Moreover, although "Wind Tornado Dragon Breath" was a wind-element alien technique, it could only be used in the Azure Dragon form and was considered a dragon's breath type of alien technique!
"Still have energy within!" Wang Luo turned and plunged back into a group of Legendary-level zombies...
The battle raged on without end. The zombies were determined to destroy the base, while the humans fought desperately to defend it. Neither side yielded, resulting in a stalemate. As time passed, the number of high-level awakened individuals increased, and the zombies no longer posed a significant threat to the base.
"Indeed, there's strength in numbers!" Zhao Qingxuan stood on the city wall, watching the awakened individuals below pushing back the zombies. If Wang Luo hadn't found so many survivors from the outside, this zombie siege would not have been so easy!
"What do we do now? Continue to slay zombies or maintain our current defensive posture?" Zhao Qingxuan asked Wang Luo.
"Since there's nothing else to do, let's kill zombies. I don't believe zombies are truly endless!" Wang Luo said. He was very curious about what lay beneath the Earth that spawned so many zombies. If possible, he even wanted to venture into the volcano to investigate. There was nothing left on the surface to explore. Apart from killing zombies, Wang Luo found nothing challenging for himself anymore.
