She was eager to know what kind of earth-shattering, awe-inspiring realm she would reach if she fully mastered the intent of the sword.

However, the system gave an unexpected prompt.

[Ding! Skill upgrade book cannot be used to upgrade top-level sword techniques. Please select another skill!]

Upon hearing this news, a hint of disappointment flashed in Jiang An's eyes, but she quickly regained her composure.

After a moment's thought, she made her decision again: "I choose advanced combat techniques!" Since she couldn't upgrade her swordsmanship, improving other skills was a good alternative.

[Ding! Upgrade successful! You have now reached the highest level of combat skill (cannot be upgraded further)!]

Jiang An stared blankly at the message in front of her, her eyes filled with confusion and bewilderment. The four large characters "Cannot Upgrade" in particular felt like a knife piercing her heart.

Looking back, there was no such prompt when I upgraded my swordsmanship.

Does this mean that there are higher levels of swordsmanship, but they cannot be improved through skill upgrade books?

The idea kept swirling in her mind, making her feel both excited and confused. Although it was just a guess, deep down she was already convinced of the answer.

Then, Jiang An quickly stored the rest of his gains in his storage ring.

Her gaze shifted to the sewing machine in the corner of the living room, a hint of anticipation in her eyes.

[Sewing machine: After use, it can be used to make various garments from various animal hides!]

When Jiang An first saw the sewing machine's description in the game's store, she made up her mind to get it.

Despite the sewing machine costing a whopping 1 million trade points, matching the price of an excellent weapon, she considered it a well worth the investment.

After all, as the game progresses, the dangers players face become greater, requiring them to confront more powerful monsters and enemies.

At the same time, the creatures they hunted became increasingly diverse, and various precious animal hides began to pile up like mountains.

Jiang An had a compartment in his backpack specifically for storing these animal skins, the number of which was simply countless.

Now that she has this sewing machine, these animal hides will become an important material for her to make clothes in the future, because the clothes made using this sewing machine will have various properties, although it is uncertain what those properties will be.

In fact, every player faces the same problem.

However, the trading points for these animal skins when uploaded to the marketplace are very low, far below their actual value.

Therefore, the emergence of this sewing machine undoubtedly brings great convenience and value to players.

As for how many players would be willing to spend 1 million trading points to buy this expensive sewing machine, Jiang An didn't know, but she knew she would definitely buy it.

Attach the needle and thread that came with the sewing machine.

He took out four wolf pelts from his backpack, put them on the sewing machine, and then chose a shirt.

As Jiang An pressed the start button, the sewing machine emitted a buzzing sound and began its work.

A minute later, an elegant top appeared before my eyes.

Jiang An picked up the newly made top and carefully examined every detail of it.

She noticed that the clothes were soft to the touch, comfortable to the touch, and brightly colored, making them look very fashionable.

Next, Jiang An checked the attributes of the top.

【Name: Women's Long-Sleeved Shirt (Regular)】

[Defense +2, Ice +5]

[Note: The size is automatically adjustable after wearing!]

Although it doesn't have many attributes, this kind of clothing is undoubtedly a very practical attribute-based garment for the next natural disaster.

Especially during the upcoming extreme heat disaster, these 5 points of ice attribute will play an important role.

In addition, the leather of this top is soft, warm, comfortable, and very breathable.

If a batch of these sun-protective garments were made and put on sale in stores, they would surely be snapped up very quickly.

With this in mind, Jiang An decided to immediately start making a batch of sun-protective clothing and put them into his backpack.

"Let's go, little turtle, let's go eat!" Jiang An said to the little turtle with a smile.

"Coo~coo~" The little turtle excitedly wagged its little tail, seemingly eager to enjoy the food with Jiang An.

After the meal, the man and the turtle dived directly into the sea to explore.

Sure enough, Jiang An could not see any living creatures in his field of vision.

It's exactly the same as the safe period.

She then increased her swimming speed and swam deeper.

Suddenly, Jiang An saw a faint light ahead. Overjoyed, she swam towards the light.

Soon, the man and the tortoise arrived at their destination.

"Mommy, it's ice marrow ore!" the little turtle exclaimed.

“Yes,” Jiang An said, and then took out two mining tools from his storage ring.

I tossed one to the little turtle.

The little turtle nimbly took it and began to huff and puff as it started digging for ore.

The same applies to Jiang An.

The extreme heat disaster is starting tomorrow, and she has been worried about the little turtle.

It is an ice-element animal, preferring cold and water, and extremely averse to heat.

In the arid and scorching desert, it's uncertain whether it can survive.

Now that we have the Ice Marrow with its cold attribute, we don't need to worry anymore. It can maintain a balance of coldness in the little turtle's body to a certain extent.

This was just a small mine, which was quickly dug up completely by the man and the turtle.

Jiang An counted and found a total of 102 pieces of ice marrow ore.

Put it directly into your backpack.

"Mommy, let's go find the baby again!" Clearly, the first haul was quite successful, giving the little turtle a great deal of confidence.

"good!"

In an instant, the man and the tortoise scattered and explored the surrounding area.

After all, the dangers at sea level are minimal now.

Time passes by every second.

The ice marrow mine seemed to have exhausted their luck; apart from finding a few herbs, they made no other discoveries.

"Little turtle, let's go, let's not waste time here!"
