Shen Muyu's heart skipped a beat when she saw the empty passenger seat. Could it be that the creatures in the dungeon couldn't be brought out? If so, wouldn't that mean she and Da Bai would be separated again after just meeting?
Shen Muyu gripped the steering wheel tightly, then calmed down. She first observed the surrounding environment and found that she seemed to have returned to the place where she first entered, but the cave that appeared in the morning was gone and had returned to the appearance of stone walls.
Shen Muyu started the car, straightened it from its side, and then stopped it close to the stone wall. She was going to check out the limited-edition shop that the electronic voice had mentioned earlier.
After opening the light screen, Shen Muyu found that the limited-time shop appeared directly on the left side, with a countdown timer next to it. Seeing that there were only 23 minutes left, Shen Muyu quickly clicked to check it out.
The moment you open the shop, an electronic voice announces, "A bond has been detected. Would you like to spend 1,000 paper money to summon the animal Big White to the tunnel world?"
"Yes!" Shen Muyu blurted out upon hearing this. Although she didn't know the purchasing power of paper money yet, she was determined to bring Da Bai back to her side no matter what, as it was something that money couldn't measure.
"Transaction complete."
As the electronic sound rang out, a huge figure suddenly appeared in the passenger seat, and many of the paper money in Shen Muyu's pocket disappeared.
"Woof woof." Seeing Shen Muyu suddenly appear beside it, Da Bai happily pounced over. Just now it thought its master didn't want to take it away.
Due to its height and weight limitations, Shen Muyu adjusted its seat to be somewhat forward. The fully grown Da Bai was unable to squeeze into Shen Muyu's arms no matter what, so it could only fall onto Shen Muyu.
Shen Muyu was thrown against the window by the pounce. She changed her position and leaned against the car door, then wrapped her arms around Da Bai's neck and started browsing the limited-time shop.
The limited-time shop has a lot of items, not only food, drinks, and entertainment, but also many materials and blueprints.
However, the items are all quite expensive, especially the blueprints. The disposable water purifier blueprint that Shen Muyu obtained before cost 1,000 paper money, and the blueprints for ordinary tables and chairs cost 200 paper money.
Shen Muyu counted the paper money in her pocket. Apart from the 1,000 she spent on Da Bai, she still had 2,030 left. If it weren't for that last woman, she probably would have been back to square one after exchanging Da Bai's paper money.
Shen Muyu spent more than ten minutes browsing through the limited-time shop. In the end, she redeemed an intermediate electronic component and an intermediate car repair kit, both of which cost 1,000 paper money, which was shockingly expensive.
However, all things considered, this is the most useful thing for her at the moment. Little A needs intermediate electronic components to upgrade, but she has never even obtained a basic one, let alone an intermediate one. So it seems that this material is something that she can't obtain at this stage.
As for the car repair kit, it was also a must. She didn't know how to repair cars, and if something happened to the car, she would be at a loss. Moreover, the product description said that it could save a car even if it was on its last legs. These kinds of things can't be faked, so Shen Muyu chose it.
Actually, besides these two items, what Shen Muyu wanted most was a firearm or a weapon that could be used for ranged attacks. After all, close combat with an axe was too dangerous. Unfortunately, such items were not available in the limited-time shop, so Shen Muyu had to give up.
With the remaining thirty, Shen Muyu bought a piece of glass. She had never seen this before, although others sold it, but the price was too high and not worth it. This was just right.
In this way, all the materials needed for Little A's upgrade are available, except that the quantity is insufficient, but this is not a problem for Shen Muyu at all.
Shen Muyu put all three items into the red backpack. Then, there were three more intermediate electronic components and three more intermediate car repair kits, and 100 more pieces of glass.
Without any further ado, Shen Muyu directly used materials to upgrade Little A, and Little A's electronic voice sounded amidst high expectations.
"Master, Little A has successfully upgraded." Little A's electronic voice seemed to carry a hint of excitement.
"Great! So, Little A, what functions do you have now?" Shen Muyu first encouraged him before asking.
After he finished speaking, a sizable screen suddenly rose up in the middle of the dashboard in front of the car, and then nine small images appeared on it. Shen Muyu leaned closer and realized that the images showed the situation around the car, and even the situation under the car.
"After the upgrade, Little A will have eyes and can keep an eye on its surroundings at any time. In addition, Little A has a new radar that can scan and analyze the surrounding environment. However, the current scanning range is very small, and it can only scan an area with a diameter of about 30 meters."
"By the way, Master, Little A has added storage space. You can import data resources into Little A, such as music or movies. Even after the car is turned off, Little A can still play them for you using the backup power."
Hearing Xiao A's words, Shen Muyu's lips curled up. Although the scanning range was not large, it could still give her an early warning, so that the enemy wouldn't be discovered until they had already crawled under the car.
As for the visual display, it can also help Shen Muyu better observe the environment around the car. After all, she only has one pair of eyes, and it is impossible for her to observe the surroundings in a 360-degree loop while driving.
"Little A, what materials do you need to level up to level three?" Suppressing his inner joy, Shen Muyu asked.
"Requires 3 high-grade electronic components, 6 magnesium-aluminum alloys, 6 titanium-aluminum alloys, 6 plastics, and 3 silver blocks."
"Hiss..." Hearing these things that he didn't recognize at all, Shen Muyu felt a headache coming on, and he didn't know if he could get his hands on them in a short time.
As Shen Muyu pondered this, her gaze suddenly fell upon Da Bai. "Why not train it? What if the dog learns to drive?"
When Da Bai saw Shen Muyu's unusual gaze, it inexplicably shrank back. But what bad intentions could its master possibly have? Da Bai quickly regained its composure and rubbed against Shen Muyu.
Sighing inwardly, Shen Muyu thought to herself, "I'd rather be the one who works harder; Gouzi needs a happy retirement."
After clearing his head of all sorts of strange ideas, Shen Muyu opened the shop. All the purified water he had listed before, except for those that required private messaging to redeem, had already been sold. It seemed that there was still a lot of demand.
After scrolling through several private messages, Shen Muyu felt a pang of regret. She was interested in several items being traded, but unfortunately, the other party's profile picture was blacked out, and the trade link was automatically locked, making it impossible to obtain them. She felt like she had lost hundreds of billions.
Just as Shen Muyu was feeling frustrated, a pop-up window suddenly appeared on the screen, and a quick glance revealed that it was Gu Wenchen.
"Use this to exchange for 500ml of purified water."
Shen Muyu looked at the drawings he sent and burst out laughing in exasperation.
