Post-apocalyptic game: I survive at sea by scavenging for trash.

Lin Zhaoyin slept straight until 3 pm. During that time, several monsters attacked the island, but Zhou Shiyun didn't wake her up and gritted her teeth to fight two monsters herself.

Fortunately, after Zhou Shiyun followed Lin Zhaoyin, her stats increased, and she also acquired a lot more equipment and weapons. During the daytime, there weren't many monsters, and they were mostly familiar species, so Zhou Shiyun was able to handle them.

Besides fighting monsters, Zhou Shiyun also went out alone to fish for treasure chests for two people. Since the fishing rods didn't recognize their owners, Zhou Shiyun used one rod in each hand and quickly caught six treasure chests.

The rest of the time, Zhou Shiyun squatted by the bedside and watched over her, afraid that she would not notice Lin Zhaoyin waking up immediately.

When Lin Zhaoyin woke up, she was almost startled by the face so close to hers.

"Sister Yinyin, you're finally awake!"

"Xiao Shi, how long have I been asleep?" Lin Zhaoyin then realized that she had simply passed out because she was too exhausted. She couldn't even remember whether the monster-hunting game had ended when she passed out.

However, she's already lying in bed, so she must have successfully completed the battle.

"Sister Yinyin, you've slept for six or seven hours. Wanyi and I were very worried about you. Are you feeling any better now?"

Lin Zhaoyin sat up and calmed herself down, finally regaining her senses. This wasn't the first time this had happened; fighting so many monsters by herself was indeed a bit of a strain.

After checking the time, Lin Zhaoyin became worried about her sister's situation.

"Is everything alright with Wan Yi? Have you been in contact with her?"

Zhou Shiyun nodded, "We contact each other every now and then. Everything is fine on her end, nothing has happened."

Lin Zhaoyin was still somewhat puzzled. Based on her own situation, she thought her younger sister might encounter a similar situation. She had been asleep for so long; the monster should have arrived by now.

If you don't come soon, my sister's pet egg will hatch tonight.

Of course, it's better if we don't run into each other. Lin Zhaoyin doesn't want her sister to be treated the same as her in this kind of situation.

However, she still needs to think this through, otherwise this matter might be a huge trap. She even gave a speech encouraging everyone to hunt bosses, which might actually harm others!

Lin Zhaoyin let her sister know she was safe and then immediately went to Qin Feng to tell him about the situation.

Qin Feng also felt that Lin Zhaoyin's encounter with the monster horde attack needed to be explained to the other players. Such a risk couldn't be concealed.

The group of monsters whose leader had been killed came to seek revenge on the player. Qin Feng didn't think it was a random event. After analyzing the situation, the two of them came up with a possibility.

The monsters in the system don't appear randomly; the game system has its own rules. The difference between Lin Zhaoyin and Lin Wanyi is that the Ice Crack Bird that Lin Zhaoyin encountered was a monster that had appeared before, while the butterflies that Lin Wanyi encountered had not yet been to the player's island.

Under the rules, monsters that have never "left" their island cannot leave without permission.

But this is just Lin Zhaoyin's guess, and no one can be sure if this is the reason.

Qin Feng originally wanted to help Lin Zhaoyin talk about this in the chat channel, but Lin Zhaoyin decided to do it herself. After all, it was her idea, and if other players wanted to criticize her, they could only criticize her.

However, there's no need to rush to confess, since Lin Zhaoyin's pet egg is about to hatch.

With only one hour left until the pet egg hatches, Lin Zhaoyin will know what's inside the egg around 5 o'clock.

However, since it was still early, Lin Zhaoyin decided to take out her previous spoils while the pet egg was hatching, so she took everything out of her backpack.

When Lin Zhaoyin saw that there was an unknown fragment inside, she was unsure why these birds had come.

She took out the previous fragments; fragments 1 and 2 had already automatically combined, and she still had a separate fragment, number 5.

Just as fragments number 4 and 5 were getting close, they also pieced themselves together.

Based on the size and shape of these two large fragments, there should indeed be a total of 6 pieces.

"Sister Yinyin, what is this?" Zhou Shiyun had never seen this before and asked curiously.

"I don't know either. We'll have to wait until all the fragments are found before we know what it is." Lin Zhaoyin was just as curious.

Now there are only two pieces left to complete the puzzle. Perhaps the mystery will be solved soon.

In today's battle, Lin Zhaoyin also obtained 200 Snow Crystals. Combined with the 150 she had previously acquired on the island, she was now close to collecting all the upgrade materials for the Ice Soul Needle.

The last piece of loot was a skill book, a B-grade skill book.

[Rank B Skill Book: Retreat, Retreat, Retreat. This skill can be obtained after learning it.]

Only skill books of rank A and above are purely blind boxes; skill books below rank A will still have the skill name written on them.

Judging from the name of this skill, it should be a defensive skill.

"Little Poetry, you should learn this skill!"

Zhou Shiyun was surprised that Lin Zhaoyin would have such a plan, and quickly waved her hand to refuse.

"Sister Yinyin, I don't want it. You worked so hard today, how can I possibly want a skill book?"

Zhou Shiyun's rejection was expected, but Lin Zhaoyin also had her own plans.

"Putting everything else aside, didn't you work hard today? You helped with those 20 Ice Crack Birds, and you even brought me back to the shelter for emergency treatment. Without you, I probably wouldn't have made it through today. This is what you deserve. You can't always keep all the good stuff for yourself, can you?"

Seeing that Zhou Shiyun was still hesitant, Lin Zhaoyin continued.

"I'm giving you this skill book because I think it would suit you better. It's clearly a defensive skill, and since you're a support, protecting yourself is the most important thing. That way, I can fight monsters with more peace of mind, right?"

Zhou Shiyun knew that Lin Zhaoyin genuinely wanted to give her the skill book, and that her reason was indeed quite valid, so she accepted the skill book in the end.

"Sister Yinyin, I'm so lucky and happy to be with you."

Under Lin Zhaoyin's expectant gaze, Zhou Shiyun immediately began learning the skill.

[Retreat, retreat, retreat. B-rank combat skill. Using 50 stamina points will trigger a protective shield, preventing enemies from getting close. The shield lasts for 3 minutes.]

Lin Zhaoyin guessed correctly; this skill was practically tailor-made for Zhou Shiyun!

"I told you this skill would be perfect for you. The three-minute shield is not only great for support, but you can also stay inside and shoot from a distance without worrying about monsters attacking you."

Zhou Shiyun nodded, overjoyed. The skill description said enemies couldn't get close, meaning this shield probably protected not only herself but also her teammates.

Although the skill consumes a lot of resources, the skill effect is really amazing!

She can test its effectiveness in the next battle!
