Buzz—
The shockwave from the oil tanker's explosion lasted for several minutes before gradually ceasing, while the dust and heat waves stirred up in the air lingered for a long time.
However, by this time, the armored vehicle had already left the area under Jarvis's control, following the route previously planned by Ray towards their destination.
"Damn, that was almost too much..."
Inside the vehicle, Ray shook his head and rubbed his ears, which were sore from the booming noise. He knew the oil tanker's explosion would be big, but he didn't expect it to be this massive.
Luckily, the residential building provided some cover; otherwise, even with the strength of the armored vehicle, they wouldn't have been able to withstand the terrifying shockwave and high temperature.
Turning his head, he saw Liu Yuqing, who had been knocked unconscious by the shock at some point, leaning her head against his shoulder.
Just as he was about to wake Liu Yuqing up, a series of system notification sounds crazily rang in his mind.
"Ding! Using the standard version nail gun to successfully kill a regular evolved zombie, reward points +100."
"Ding! Using the oil tanker explosion to successfully kill two thousand one hundred thirty-seven zombies! Reward points +2137."
"Ding! Using the oil tanker explosion to successfully kill two regular evolved zombies! Reward points +200."
"Ding! Congratulations to the host for completing the [Five Hundred Kills] achievement task! Reward [Basic Stamina Enhancer] one bottle!"
"Ding! Congratulations to the host for completing the [One Thousand Kills] achievement task! Reward [Fine Grade Nepalese Kukri] one!"
"Ding! Congratulations to the host for completing the [First Kill Evolved Zombie] achievement task! Reward [LV2 Armored Vehicle Modification Card] one!"
...
"Made a fortune, made a fortune..."
Ray, with excitement in his eyes, quickly opened the system to check the reward log.
"Stamina enhancer? Good stuff!"
"Both strength and neural response have been enhanced, and with this enhancer, it's just right to make up for the shortcomings in stamina."
"A fine-grade Nepalese Kukri?"
"Wow? An LV2 armored vehicle modification card?"
Ray went through the rewards one by one until all were distributed. Without hesitation, he opened the system backpack and began to use them.
First, he took out the [Basic Stamina Enhancer], which looked similar to the strength enhancer and neural response enhancer he had taken before, just in a different color.
[Basic Stamina Enhancer]: After taking it, permanently increase the stamina attribute by 20 points within ten seconds.
The effect was similar to the previous two potions, permanently increasing an attribute by 20 points.
After reading the effect, Ray twisted off the cap and drank it in one gulp.
"Um! This tastes pretty good, quite sweet."
Feeling a sweet taste spreading in his mouth, Ray smacked his lips, immediately bracing himself for the pain that would follow.
However, to his surprise, this time was completely different from the previous two occasions. The previous times involved either whole-body itching and soreness or severe headaches. This time, after drinking it, not only was there no pain, but there was also a feeling of being refreshed and full of energy!
"Awesome!!"
"The lack of sleep from last night, all gone in an instant!"
Ray clenched his fists, feeling as if there was an endless supply of energy inside him, and couldn't help but exclaim in amazement.
After getting familiar for a couple of minutes, Ray's gaze fell on the second reward [Fine-Grade Nepalese Kukri].
Ray pulled the fine-grade Nepalese kukri from its genuine leather sheath, felt its grip, and casually swung it, cutting through the air and producing a faint slicing sound.
Extremely sharp!!
"From a shotgun to a cannon, a good knife!"
Ray, with a smile, put away the kukri, his gaze landing on the final reward, and the one he was most looking forward to.
The LV2 Armored Vehicle Modification Card!
[LV2 Armored Vehicle Modification Card]: Can be used on an LV1 armored vehicle, transforming it into an LV2 armored vehicle within ten minutes!
"Does upgrading to LV2 take ten minutes?"
After looking at the effects of the modification card, Ray touched his chin, somewhat surprised but also understanding.
However, to upgrade the armored vehicle, it must be stopped and turned off.
Ray looked at the vehicle's onboard control screen display, noting they had left the supermarket area by five or six kilometers.
Looking outside, he saw that under Jarvis's control, the armored vehicle had gradually left the Huarong District on Daxi Street. Sparse zombies could still be seen along the road, and compared to the Huarong District, there were significantly fewer buildings.
In addition, along the road, they could occasionally see vehicles that had been crashed to scrap, overturned and abandoned, as well as skeletons that had been gnawed clean.
As for survivors who, like him, had taken this road to leave the Huarong District, he hadn't seen a single one.
He didn't know if they had left early, were trapped in the Huarong District and became zombie food, or were killed by the oil tanker explosion he caused.
"Let's drive a bit further, find a place that's open, with good visibility, and fewer buildings to use it."
Subsequently, under Ray's observation, the armored vehicle continued along the main road for another two or three kilometers, until he found a suitable location.
This was a crossroads in the outskirts, where no buildings could be seen around. Although wrecked vehicles were still everywhere, they didn't pose much of a problem for him.
As for the zombies wandering nearby, he easily cleared them out by opening the sunroof and using the standard nail gun.
"Let's use it here."
After clearing the zombies and getting back inside, Ray closed the sunroof, put away the nail gun, and took out the [LV2 Armored Vehicle Modification Card], choosing to use it on the armored vehicle just like last time.
"Ding! [LV2 Armored Vehicle Modification Card] successfully used!"
"Target: Current LV1 armored vehicle!"
"Time required: 10 minutes!"
"Beginning modification..."
As the card disappeared and the system's notification sound rang out, the LV1 armored vehicle he was in began to be modified from the outside in, just like before.
The ten minutes passed quickly. Ray took a bottle of water, drank a few sips, and waited a bit.
By then, the LV1 armored vehicle had undergone earth-shattering changes.
Checking the LV2 armored vehicle's data on the system, he found that not only had the body become longer, wider, and taller, but the interior space had also increased, adding a position for a large bed, comparable to a compact RV!
And it even came with its own storage warehouse!
The maximum speed limit had also increased, reaching a top speed of 200 kilometers per hour!
Additionally, the fuel tank had changed, its capacity increased to 500 liters, with a cruising range of 1500 kilometers, and it came equipped with its own generator!
Most importantly, the defensive level of the LV2 armored vehicle's body had truly reached the point where it could withstand anti-tank mines! Absolutely incredible!
The weight of the vehicle had reached an astonishing fifteen tons!
From a functionality perspective, it far surpasses a regular land tank!
Ray shifted his gaze from the data displayed on the system, looking around the interior space of the vehicle, which had expanded several times over, with a face full of surprise. He noticed that the previously packed rear seat full of supplies had been completely cleared out, all gone!
Everything had been automatically placed into the storage warehouse during the armored vehicle's upgrade!
And this storage warehouse was located under the large bed that had been added to the rear compartment!
The interior space of this LV2 armored vehicle could not be said to be small!
The supplies that previously filled the vehicle now only occupied the space under one bed!
