The doomsday ruins originated from a doomsday world, where there was once a global conglomerate called the Umbrella Corporation.
On the surface, Umbrella Corporation dealt in high-tech products such as pharmaceuticals, medical equipment, and industrial goods, but secretly, they engaged in life engineering and biological weapons research.
The root of all disaster stemmed from Umbrella Corporation's discovery of an ancient virus from a composite plant found in some ruins. They intended to use this virus to create biological weapons.
The biological weapons were successfully created, but they could not control them. An accident occurred, and the virus spread rampantly through infection, creating a large number of zombies and plunging the entire world into an apocalypse.
Inside the Umbrella Corporation's base, there was the virus that could infect people into zombies, as well as a vaccine that could prevent infection. As long as one could obtain both the virus and the vaccine, they could inject the virus first to significantly enhance their physical strength, then inject the vaccine to ensure they wouldn't turn into a zombie, thus becoming stronger.
Bai Ye, decisive, immediately took action.
Soon, Bai Ye arrived before a towering, abandoned skyscraper.
Before the apocalypse, this skyscraper was outwardly an office building for a biotechnology company, but in reality, it was the location of Umbrella Corporation's secret base.
Upon entering the building, the lobby elevator still worked, but Bai Ye didn't press the buttons immediately. Instead, he forcefully punched the area below the number keys.
The next moment, a metal cover sprang open, revealing another button that indicated minus fifteen floors.
That was the secret base of Umbrella Corporation!
Frankly, obtaining the virus and vaccine was not an easy task, as even the entrance to the base was more hidden than expected and not easily found.
However, none of this was difficult for Bai Ye, because he had been here in his previous life!
At the same time...
As the elevator descended, the voice that had appeared earlier sounded again.
"Due to a participant discovering and entering the restricted zone, Umbrella Corporation's underground base, all participants currently in the doomsday ruins area will be transported to different locations within the Umbrella Corporation's underground base in three minutes."
"Restricted Zone Mission 1: Find Umbrella Corporation's research documents on the virus. Mission Reward: T-Virus x1."
"Restricted Zone Mission 2: Obtain a sample of the original virus. Mission Reward: T-Virus Vaccine x1."
"Restricted Zone Mission 3: Obtain a gene sample of 'Nemesis.' Mission Reward: G-Virus x1, Shard of Godstone x5."
"Gentlemen, for the sake of obtaining Shards of Godstone, please fight hard."
...
Within the doomsday ruins, countless participants showed surprise, while Bai Ye nodded with satisfaction, as the mission was exactly as he had experienced in his past life.
At the same time...
...
World Battlefield, Central Tower!
At the center of the World Battlefield stood a white jade tower reaching into the clouds.
This was the core of the World Battlefield, the hope of the chosen, and was known as the dwelling place of gods, for it held the exit from the World Battlefield, the Gate of Divine Selection.
However, reaching this place was incredibly difficult.
The condition of possessing ten Shards of Godstone was not easily met, and the central area was considered the most dangerous region, with every inch of land harboring terrifying entities capable of causing death.
And in his previous life, Bai Ye had already stood before that gate!
Just a little more...
At this moment, on the top floor of the Central Tower.
It was a dim, octagonal hall, so dark that visibility was impossible.
But then...
The sound of flickering flames suddenly appeared. Immediately, a candle on the wall ignited, illuminating the area ahead.
In the dim light, a long bench could be seen. A man sat on the bench, but only his vague outline was visible, his face hidden.
"The first restricted zone has opened," a low voice suddenly said. "This is incredible. The World Battlefield has only been open for less than two hours, why has the restricted zone opened so soon?"
As the voice fell, another candle on the opposite wall lit up, and in the dim light, another humanoid silhouette appeared on the other side of the octagonal hall.
"If no one could do it, would we still need to sit here?"
"That's true. The fact is, someone actually did it."
"I'm very curious, from which world does this person come? Is it from the cultivation world? Everyone knows people from that world are very powerful. Even when they first enter the World Battlefield, they possess extremely strong combat abilities. They even often fantasize about challenging the gods."
"It could also be from the power world. People from that world have some bizarre abilities. Truly wondrous beings, who created them?"
In another corner, another candle lit up, and with the sound of voices, humanoid silhouettes of two men and one woman appeared under the dim candlelight.
"Alright, put aside your curiosity. It doesn't matter what world that little guy is from. What's important is that we need people like that to give us surprises, don't we?"
"That seems to be true. Perhaps we can look forward to it?"
"It seems things are becoming interesting!"
As the voices faded, the candlelight in the octagonal hall extinguished one by one, plunging it back into darkness.
...
Abandoned Building, Elevator!
Bai Ye stood with his arms crossed, waiting.
As a second method of obtaining Shards of Godstone besides combat, some people once naively believed that by focusing on conquering restricted zones, they could gather enough Shards of Godstone.
In reality, the competition for restricted zones was even more brutal, because every time a restricted zone opened, all people within that zone would be transported into it.
Combat was still inevitable.
In fact, because the restricted zone missions were limited, the competition would become even more intense for these missions.
A moment later, the three-minute countdown ended, and the elevator Bai Ye was in stopped at the lowest level.
The elevator door slowly opened...
But at that moment...
Bang!
A thud suddenly echoed, followed by a nearly rotten arm thrusting into the elevator, attempting to grab Bai Ye's clothes.
This sudden turn of events startled Bai Ye. Fortunately, having returned to ten years ago, Bai Ye's memories were not taken away, and his past combat experience allowed him to react instinctively. The moment the arm appeared, Bai Ye dodged to the side.
The next instant, Bai Ye raised the pistol in his hand. The moment the elevator door fully opened, Bai Ye pulled the trigger.
With a bang, a gunshot rang out, and a zombie fell backward, crashing heavily onto the floor.
