How could she forget that she still had the skill to turn waste into treasure!

Lin Chu immediately placed her hand on the one-shot pass, but after a while, there was no response.

That’s when she remembered that she had already used the skill to turn two boxes of fruit into treasure earlier.

The number of uses for that day’s skill had been exhausted.

She would have to wait until the next day to use it again.

Her enthusiasm had cooled slightly, and Lin Chu glanced at the time—it was already 10 PM.

She gathered all the materials on the floor and stored them in her space, cleared the area, and changed into her workout clothes to begin her evening physical training.

After some high-intensity training, Lin Chu could clearly feel her cardiovascular function improving.

With the help of a body-strengthening pill, her strength had increased significantly compared to before.

Earlier, when fighting zombies, she needed to use technique to land a headshot. Now, she could easily crush their heads with brute force.

Lin Chu was very pleased with her training results.

After training, she took a shower to wash off the sweat and then went to bed.

However, the failure to modify the one-shot pass remained on her mind.

No matter what she tried, she just couldn’t sleep.

As she saw the system clock pass midnight, Lin Chu suddenly jumped out of bed.

She took the one-shot pass out of her space again.

She noticed that the steel tube she added in front of the launch head had fallen off, with a slight crack at the original connection.

Lin Chu reattached the steel tube to the one-shot pass’s launch head.

This should… count as waste, right?

After all, according to the design of a modified gun, it really was useless.

She wasn’t sure how the skill would determine whether it was waste, though.

Unable to figure it out herself, Lin Chu decided to simply cover it with her hand.

Soon, a white light lit up.

When the white light faded, Lin Chu looked at the one-shot pass in her hand, and her eyes slightly brightened.

The rough connection between the steel tube and the one-shot pass was now smooth and even, as if it had been seamlessly integrated.

The originally bright silver shell had turned into a low-key matte black.

The pump handle, which had originally resembled a bicycle pump, was now a small pull ring.

Lin Chu tried pulling it lightly, and the pressure gauge jumped to 2, where it stayed.

The maximum pressure was 10.

She discovered that after the transformation, the one-shot pass required much less effort to pressurize—by simply pulling the ring at the back, she could easily reach the maximum pressure of 10.

Upon closer inspection, Lin Chu noticed an additional cylindrical steel ball inlet where she had added the steel tube.

Now, instead of loading steel balls from the top, she could insert them through this modified cylindrical inlet, and they would enter the barrel as usual.

This transformation felt as if the system had read her mind, perfectly modifying the item to include all the features she had hoped for.

Suppressing her excitement, Lin Chu focused on the string of text that had already appeared in her mind.

Item: Toilet Inflatable Gun
Rarity: A
Item Description:
“Emmm, seems like this is a waste-turned-treasure item made from something not-so-wonderful. It’s welded with high-quality steel, durable, and compatible with any steel balls with a diameter of less than 1 cm. Using steel balls with it improves the effect.”

Seeing this name, even Lin Chu, who was usually calm, couldn’t help but twitch her mouth.

The system had referred to the one-shot pass as “something not-so-wonderful,” which clearly showed its disdain.

Perhaps because of this disdain, it had intentionally used high-quality steel for the modification. The current one-shot pass—no, the toilet inflatable gun—no longer resembled its original form in the slightest.

Its all-matte black finish exuded a sophisticated aura.

Lin Chu was very satisfied.

If only they had left out those first two words in the name, she would have been even more satisfied.

After a moment of thought, she took an empty mineral water bottle from her space, filled it with water, and placed it on the floor.

She stepped back to the corner, placed a steel ball in the barrel, lifted the inflatable gun in her hand, and pulled the ring at the back.

Pressure: 10
Fire!

“Bang—”

Water splashed everywhere.

The power was at least twice as strong as what she had modified.

Lin Chu walked over to inspect, and found that the steel ball she fired had pierced through the water-filled bottle, and with its momentum, it hit the wall behind the bottle.

A small hole about 5 cm deep had been made in the wall, and the steel ball was embedded in it.

Lin Chu retrieved the steel ball with a pair of tweezers she found in her space.

She couldn’t help but glance worriedly at the hole in the wall.

“System, what happens if the wall of the shelter is pierced?”

Host, the shelter uses advanced spatial folding technology. If the wall is breached, do not extend any part of your body through the hole. Simply wait for the wall to self-repair.

Self-repairing walls?

This was the first time Lin Chu had heard of such a thing.

She immediately looked down.

She saw that the 5 cm deep hole had started to repair itself, with the gap visibly shrinking in real-time. After 5 seconds, the small circular hole of about 1 cm had completely disappeared.

The wall was as good as new.

If not for the water all over the floor, which proved what had just happened, Lin Chu would have almost thought it was just her imagination.

After regaining her composure, Lin Chu cleaned up the broken bottle and wiped away all the water splatters in the room.

By the time she finished, it was already 1 AM.

She didn’t waste any more time and stored everything back in her space before going to bed.

Though it was late, she woke up at 6 AM as usual the next day.

Her daily routine involved training, breakfast, dissection, and a trade with Zheng Ziyu at 9 PM.

The next 4 days passed peacefully.

With only 2 days left before the mission world ended, he still hadn’t returned.

Lin Chu couldn’t help but feel a bit worried.

On one hand, she was concerned about losing a good partner.

On the other hand, she also worried about the F City Survivor Base.

The base was only about a hundred kilometers away from her park.

If Yu Hongfei’s mission was this difficult, there was a good chance something was wrong at the survivor base.

And it might not be a small problem.

If such an official base had an issue, it could cause turbulence in surrounding cities.

Her mission progress was more than halfway done.

In 8 days, she would complete her survival mission in this world.

She didn’t want any more major setbacks.

She had stopped dissecting zombies today.

The task limit with Zheng Ziyu had been reached.

Lin Chu hadn’t taken on any tasks recently.

She had stored up 17 dissected zombies.

If Yu Hongfei didn’t return, she would only need to submit 7 zombies, leaving 10 as overflow.

She could only slow down her progress and wait.

Just as Lin Chu was anxiously waiting for Yu Hongfei’s return, she heard a noise outside her bathroom door.
