Waldo's heart was eager as he hurried back to the underground bunker.
The upgraded intermediate-level underground bunker was covered with S alloy on the foundation and walls, forming a metallic room.
After the upgrade, the intermediate-level bunker had additional attributes such as resistance to cold, heat, and lightning strikes. Only when upgraded to the intermediate level could it be considered a true refuge.
After all, the villa where Waldo and others lived could only withstand zombies, while a basic underground bunker could only withstand meteor showers. If there were extreme disasters in the future, such as lava rain or ice and snow storms, a intermediate-level bunker would be needed.
Although there were no signs of lava rain or ice and snow storms at present, it was better to be prepared and upgrade early to avoid future troubles.
Waldo opened the information panel of the underground bunker.
[Underground Bunker]
Level: Basic
Description: S alloy underground bunker with basic defense capability, capable of withstanding most disasters.
Clicked on the upgrade button.
[Do you want to upgrade the underground bunker?]
[Yes/No]
Waldo clicked "Yes" without hesitation.
[Underground Bunker (Intermediate Level)]
Upgrade materials: Concrete (5000/5000)
S alloy (165/20)
The five thousand units of concrete and twenty pieces of S alloy in the backpack disappeared with a beep, and then, through transformation, the underground bunker was upgraded.
The underground bunker expanded outward from its original foundation. The basic underground bunker was built based on the basement of the villa. This time, the expansion of space extended in the direction of the villa's courtyard.
Waldo witnessed the underground bunker gaining an additional area equivalent to the villa's courtyard on the surface.
Now, they had a place to store the fresh fruits and vegetables they grew. Moreover, they had plenty of space because the area was much larger than the villa's courtyard, which also had a garage, flowerbeds, and ornamental trees.
[Underground Bunker (Intermediate Level) Upgrade Complete]
[The bunker has acquired new attributes: Resistance to cold, heat, and lightning strikes]
After completing the upgrade, Waldo went upstairs to inform Alanna and Helen of the news. Both of them were initially surprised. They had just been wondering how to gather enough concrete to upgrade to the intermediate level, but in the blink of an eye, the upgrade was completed.
However, they quickly shrugged it off, thinking it didn't matter since it had already been upgraded! They assumed that Waldo must have found a team that provided concrete.
The three of them happily moved all the fruits and vegetables from the courtyard and rooftop terrace to the underground bunker. They hung many fluorescent lights in the growing area of the bunker to ensure photosynthesis for the crops.
Mission accomplished! Waldo wiped the sweat off his forehead. He didn't feel how tiring it was to move the fruits and vegetables up and down the stairs. The only thing in his mind was the joy of seeing the crops he had diligently cultivated being safe from harm.
At the same time, with this problem resolved, which had been bothering them, Waldo could fully focus on preparing for a trip to the old city district.
After a good night's sleep, the next morning, Waldo immediately received today's unlimited supplies.
Unlimited 7.62mm bullets! This was a powerful weapon! The 9mm bullets could only be used for pistols and submachine guns, and their power was always somewhat lacking. Now, with the unlimited 7.62mm bullets, and once he acquired a rifle, their strength would increase significantly.
Most importantly, the Gatling machine gun in the courtyard finally had a purpose, and they no longer had to worry about running out of ammunition.
After having their fill, they were ready to set off!
On the highway, it was terrifyingly silent. There were no cicadas chirping, no breeze blowing, only endless silence. In the distance, the roar of a car broke the silence of the road, bringing a bit of liveliness.
The car was speeding, its wheels crushing the asphalt road, making a swooshing sound. The worn-out roadside signposts were blown away by the whirling wind, dropping with a clattering sound.
The oil stains on the signpost were faded due to time and rain, but a few words could still be discerned: Industrial City.
This was already the third consecutive hour that Waldo had been driving, and he had encountered and dealt with many zombies along the way. When he reached deserted sections of the road, he would step on the gas pedal to the max.
Feeling excited, he would even hum a song.
"The dark night is slippery, and this society is complicated." Waldo hummed the song, and suddenly he saw a crumbling road sign that read "Industrial City" in three words. He knew that he had reached his destination.
After entering the old city district, Waldo stopped the car and walked slowly on the city streets. The name "old city district" was indeed fitting. The architectural style of the streets resembled that of the real world, the white-brick-red-tile style of the 30s and 50s.
Even the sidewalks in front of the shops were paved with crushed stones and cement. Waldo saw a barber shop with shattered windows and broken glass.
Looking at the old-fashioned barber chairs and round mirrors that were still intact, he felt as if he had returned to his childhood. It seemed that this old city district had remained unchanged for more than a decade.
Clack, clack, clack. Waldo heard a sound coming from the second floor of the barber shop. It was the sound of someone descending the stairs. The one coming down was a zombie.
It was wearing a moss-green vest, had a Mediterranean hairstyle, and was wearing knee-length shorts and sandals. It looked at Waldo and let out a low growl.
Waldo put down the curiosity in his hand, a pair of scissors, and smiled faintly, "Uncle, I'll be leaving now. Goodbye." The zombie growled again and rushed towards him.
Pop, pop, pop! Waldo took out his UMP9 submachine gun and accurately shot the zombie in the head. After long and costly practice, Waldo's marksmanship had become quite accurate.
Although he couldn't compare to a sharpshooter, he was no longer like before, unable to aim at a zombie standing in front of him.
After dealing with the zombie, Waldo went upstairs. He was just casually strolling around and didn't expect to find anything valuable.
However, on the second floor, he discovered a bronze-level supply box. Waldo put two bottles of water and a bag of bread into his backpack, surprised by the density of supply boxes in the old city district.
They had just entered the area, and even while wandering around a barber shop, they could find a bronze-level supply box. If they went further in, wouldn't there be a whole bunch of silver-level and gold-level boxes?
No wonder Sheriff, that old fox, was so decisive in developing the central district and now wanted to develop the old city district. Tsk, the villa area was only suitable for retirement.
After slightly adjusting his emotions, Waldo walked out of the barber shop and continued deeper into the old city district. The old city district wasn't particularly large. If driving at normal speed, it would take less than half an hour to travel from south to north.
However, considering Waldo's walking speed, it would still take some time to reach the central area of the old city district. Waldo didn't deliberately hide and walked openly on the roads of the old city district, wearing his combat gear, ready to face the zombies that charged at him. The zombies were organized.
Currently, they were just ordinary groups of zombies, so he could confidently walk on the streets. Waldo had great confidence in his own abilities. Wearing his combat gear, holding his UMP9 submachine gun, and carrying a critical strike warrior knife on his back, he was not afraid of zombies.
Of course, if there was a zombie horde, he would strategically retreat without turning back. Alternatively, he could hide in an armored vehicle and drive away.
Waldo had once watched videos of zombie hordes in the old city district that other survivors had posted in the chat channel. When the horde attacked, the street where he currently stood would be completely blocked by zombies!
