Still in the hardware and miscellaneous store on the second floor, Ray entered and got straight to the point.
"System, I want to modify this indirect-fire nail gun again. Do you have any good plans?"
"Ding! There are three secondary modification plans for the indirect-fire nail gun, each requiring different materials and points."
The system's voice immediately responded.
Three secondary modifications?
Ray was slightly surprised; after all, the first modification only had two options. He immediately asked, "What are the three options?"
"Ding! They are the direct-fire nail gun plan, the mid-range version of the indirect-fire nail gun plan, and the heavy-duty indirect-fire nail gun plan."
"I'm familiar with the first one; it uses gunpowder as propulsion, with an effective range of 30 meters. What's the difference between the second and the third options?"
"Ding, the mid-range version of the indirect-fire nail gun is powered by stronger compressed air, with an effective range of 40 meters, capable of piercing an 8mm thick steel plate within 10 meters, and can load twenty nails. It requires six types of materials and 100 points!"
"The heavy-duty indirect-fire nail gun is powered by triple-strength compressed air, with an effective range of 150 meters, capable of piercing an 8mm thick steel plate within 80 meters, and can load five steel nails at a time. It requires eight types of materials and 100 points!"
The system explained.
"This mid-range version of the indirect-fire nail gun is more powerful than the direct-fire nail gun and requires 20 more points than the direct-fire option. As for this heavy-duty indirect-fire nail gun..."
Ray looked at the system's description of the heavy-duty indirect-fire nail gun, "With an effective range of 150 meters, and it can only load five steel nails at a time, it's somewhat similar to a light sniper rifle."
By now, all the materials on the ground had disappeared, replaced by two brand-new nail guns.
One appeared smaller than before, and the other looked larger and longer.
Ray first picked up the smaller one, the mid-range version of the indirect-fire nail gun.
It was much smaller than the original, now only slightly bigger than a palm, and resembled a pistol in appearance. The difference was its hammer section, which featured two 5cm square compressed air tanks sitting side by side, tightly packed together, and beneath it, a small pump lever for inflation.
"The original 5cm diameter, at least 20cm long air jet tube, has become so small, but the grip has improved a lot. The appearance is not as rough as before, hmm, and it's more portable."
After examining it briefly, Ray nodded.
"Let's see how powerful it is."
Saying so, Ray disengaged the safety of the nail gun, raised his hand, and pulled the trigger towards a shelf.
Bang!
Puff!
The sound of the gun firing and the tin being pierced occurred simultaneously.
Ray re-engaged the safety and walked towards the shelf he had aimed at to see where the nail had ended up.
Passing through three side-by-side shelves, he only saw the small holes left by the nail's passage and did not find the nail itself!
Although the metal of the shelves was not thick, each shelf had two layers, and each was spaced two meters apart!
Yet the nail had pierced through three shelves in a row, only to be found in the fourth shelf by Ray!
The power was undeniably great!
"Being close probably played a role as well!"
Ray smiled, satisfied, and then stored away the mid-range version of the indirect-fire nail gun.
As for the heavy-duty indirect-fire nail gun, it was as he had guessed, indeed a light sniper rifle, with an appearance similar to the SKS. The difference was in the hammer area, where three square compressed air tanks were tightly fitted together in a '品' shape.
Picking it up, Ray immediately felt a very familiar sensation, realizing, "It seems that the advanced close combat techniques also include some usage of light sniper rifles."
Due to the immense power of this nail gun, to avoid alarming the zombies outside the supermarket, Ray didn't test its actual power.
He turned and found two larger tote bags, placing the gun inside one of them, then scoured the hardware section for nails and steel pins, emptying the supplies into the bags.
"It's not full yet, let's find some knives as backups."
Saying so, he found several sharp watermelon knives and placed them into the tote bags as well.
"That should do it. Let's put these in the car and head back to the fifth floor for something to eat. If we don't go back soon, Liu Yuqing might start getting anxious."
Ray, carrying two tote bags, came to the bathroom window, asked Jarvis to open the armored vehicle's sunroof, jumped down from the second floor to the roof, and placed the bags of nails and steel pins into the armored vehicle.
When he returned to the fifth floor, even before he got close to the restaurant, a delicious aroma was already wafting towards him.
