"System, accelerate the timeline," Lu Jie said casually.
There was no point in watching anymore; it was better to let the system speed up the timeline and move on to the crucial plot.
[With the sample brought back to the Xuan Nation, Zhao Xian realized the terrifying nature of the mutated MR virus and began researching it with all his might. Meanwhile, the Grand Elder decisively withdrew defenses, abandoning much of Yazhōu's land and allowing all Xuan Nation citizens abroad to return after undergoing a thorough inspection.]
[One week later, the Grand Elder of Xuan Nation issued an order for an intercontinental missile carpet bombing of the mutated Tyrant Zombies. The area within dozens of kilometers of the Hasa Nation was turned into a sea of fire. After struggling for a while, the mutated Tyrant Zombies ultimately perished.]
[However, the Super Zombies consumed the mutated Tyrant Zombies after their death, absorbing the intense mutated MR virus within them, and began evolving to a certain extent.]
[One month later, the Super Zombies, along with millions of zombies from the Haihaio Continent, headed toward Xuan Nation, hoping to devour large amounts of flesh and blood to continue their evolution. Meanwhile, the mutated MR virus also spread into Xuan Nation. Despite extensive precautions, many were still infected and turned into zombies, though the Xuan Nation's guards and military eliminated most of them. While the entire nation was thrown into turmoil, it didn't escalate into a major crisis.]
[The appearance of the zombie tide triggered nationwide alerts, and long-range bombardments were launched to deal with the swarm. Despite the millions of zombies, they still couldn't break through Xuan Nation's borders. Eventually, the Super Zombies abandoned the horde, using it as bait to stealthily enter the country and easily turned one city after another into a bloodbath. Many Xuan Nation citizens were infected and transformed into zombies.]
[In response, the Xuan Nation Council of Elders was furious and decisively used intercontinental missiles to flatten several zombie-controlled cities. At the same time, they further contracted their defenses, mass-producing gene serums and forming superhuman units. Fully equipped, these superhuman soldiers began hunting the Super Zombies.]
[However, because the Super Zombies possessed significant intelligence and were highly cunning, they could only be killed by a full-on assault immediately after their traces were found. Once the Super Zombies infiltrated cities, it became a disaster. As a result, the extermination operation didn't go smoothly, leading to a protracted tug-of-war. The overall situation in Xuan Nation gradually worsened.]
[The battle dragged on for five years. During this time, the number of Super Zombies increased, while the human population sharply decreased, and most cities fell. The remaining one hundred million humans were holed up in three massive super cities surrounded by steel walls towering over 200 meters, heavily guarded by the superhuman army.]
[Living within these steel cities, human life had become increasingly difficult due to food shortages. However, thanks to five years of research, the mutated MR virus antidote was developed, preventing widespread infections from airborne virus transmission.]
[Even Super Zombies found it difficult to break into the steel cities, guarded as they were by superhuman soldiers. Thus, the war between humans and zombies fell into a deadlock.]
[Another year passed, and the chief biochemist of humanity, Zhao Xian, in collaboration with top scientists, successfully developed Gene Serum 2.0. The Grand Elder painfully injected 300,000 loyal soldiers with the serum. 250,000 soldiers died, but the remaining 50,000 successfully enhanced their genes and became new humans, forming a 50,000-strong elite force capable of fighting Super Zombies head-on, becoming humanity's trump card.]
"Six years, and they've developed Gene Serum 2.0 already," Lu Jie said as he stood in midair, looking down at the steel city below with a faint smile.
In the Biochemical Apocalypse: New Humans archive, Elder Zhao spent 15 years to develop the serum.
The situation here was dire, but the number of talents and resources far exceeded those in the New Humans timeline. No doubt it had advanced by nine years.
"Looks like humans only tap into their potential when faced with extinction," Lu Jie mused.
"Let's hope they can develop Gene Serum 4.0 this time," Lu Jie muttered to himself.
[As Lu Jie pondered, another sudden change occurred in Xuan Nation.]
The system's voice interrupted his thoughts, snapping him back to reality.
At this moment, his figure was transported to another location. Below him, there was a sea of zombies, stretching endlessly.
Among them, several were towering Super Zombies, including one whose size nearly rivaled that of the mutated Tyrant Zombie.
[After years of futile attacks, the Super Zombies chose to gather zombies from the entire Oya Continent. A horde of 2.5 billion zombies surrounded the last remaining steel cities of Xuan Nation.]
"2.5 billion zombies?" Lu Jie inhaled sharply as he looked at the endless sea of zombies below.
The population of the entire Haiya Continent was around 5 billion. Though Xuan Nation's previous crackdown had reduced the zombie population significantly, it still remained high due to the nation's collapse.
2.5 billion? Even if they killed endlessly, they could never wipe them all out. The number alone was terrifying.
Humans could never amass such an army.
But zombies, on the other hand, didn't need food. This horrifying reality was now about to unfold.
"Humans are in trouble now," Lu Jie frowned.
With 2.5 billion zombies surrounding the steel cities and only 50,000 new humans to defend them, it was clear that the defense wouldn't hold. Let alone the fact that the number of Super Zombies alone already outnumbered the new humans.
The city couldn't be defended, and there was no way it would survive.
Even if they could hold off the Super Zombies, the regular zombies could form a flesh wall and flood the cities.
With so many zombies, the ordinary citizens would be consumed to the last.
Even those who had been injected with the mutated MR virus serum couldn't be infected by regular zombies. But they could still be eaten clean, their fates sealed.
Only Super Zombies had the ability to infect those injected with the serum.
"Looks like there's only one option left for humanity," Lu Jie murmured, narrowing his eyes.
As Lu Jie had expected, the high-level leaders of Xuan Nation were now in complete chaos.
"The satellite feed on the live broadcast made everyone in the conference room shudder, and the atmosphere became chaotic."
"Enough!" The Grand Elder slammed the table, his face grim. "Silence!"
With the Grand Elder's command, everyone fell silent, their expressions varied, though most were numbed, staring blankly at the terrifying scenes projected before them.
