After dinner, Xia Wan stretched and pretended to be exhausted. She made an excuse that she was too tired and went back to her room to rest.

However, only she knew in her heart that the so-called fatigue was just a pretense.

In fact, she was really looking forward to going up the mountain at the same time as yesterday to find out if she could run into Wu Sangui delivering food to that mysterious woman again.

At this moment, she was full of energy, as if she had been injected with chicken blood, and there was not a trace of drowsiness in her eyes.

Back in her room, Xia Wan started rummaging through drawers out of boredom. Since it was still early before heading up the mountain, she packed her things.

Suddenly, her gaze was drawn to an inconspicuous box in the corner, the very box she had found by chance at the scrap yard.

At the time, she felt that the weight of the box was a bit off, but no matter how she searched the surface of the box, she could not find any mechanism or hidden compartment.

This time, Xia Wan held the box in her hands and gently shook it a few times.

Just then, a faint sound came from the crack in the wood, as if something was moving back and forth inside.

Xia Wan's eyes lit up instantly, and an overwhelming joy welled up in her heart: Could it be that she had really struck it lucky this time and found some incredible treasure?

For example, the legendary big goldfish, small goldfish, etc.?

Thinking of this, Xia Wan couldn't help but feel secretly pleased. After all, her luck had been quite good ever since she transmigrated to this strange world.

So, even if you really do encounter something like a goldfish, it doesn't seem like it's entirely impossible!

At this moment, Xia Wan narrowed her eyes slightly, staring intently at the box in front of her, and muttered to herself, "This wood looks ordinary, nothing special. In that case, I might as well just smash it open and take a look, consider it a chance to try my luck and win a prize!"

As she spoke, she rolled up her sleeves, ready to open the box and find out what was inside...

She muttered to herself, "It seems like I never feel disappointed when it comes to things related to luck!"

Muttering to herself, she didn't stop what she was doing. Suddenly, she exerted all her strength and pried the sturdy box open.

"Haha, this saves so much trouble, I don't even have to look for tools!" she said excitedly to herself, but soon felt a sharp pain in her palm—after all, this box wasn't so easy to pry open.

However, this pain is nothing to her; she should recover quickly after a short while.

However, when she looked into the box with great joy, she was stunned.

Instead of the goldfish I expected, I was surprised to see a stone that looked quite familiar.

Xia Wan frowned slightly, feeling puzzled. With a thought, she instantly retrieved the stone that Li Zhenzhen had sold her earlier from her spatial storage.

Upon closer inspection, the two stones were practically identical, not only in size and texture, but also in that they could be pieced together perfectly!

Xia Wan carefully placed the two stones together and meticulously pieced them together. At that moment, a peculiar shape clearly appeared before her eyes.

Just then, the system's familiar yet cold voice suddenly rang in her mind.

[Abnormal energy detected. Host, would you like to level up?]

Upon hearing the notification sound, Xia Wan was taken aback: "Strange energy? It actually comes from this stone?"

You know, even a powerful system can detect the special energy contained within it. Could it be that this seemingly ordinary stone really hides some unknown secret or great value?

Thinking of this, Xia Wan's heart involuntarily quickened.

No wonder Huang Qiujie was able to gain so many benefits from this half stone; it turns out it was a treasure.

The stone itself is just ordinary Hetian jade, but the energy it contains is different, especially after the two stones are put together, the energy is even greater.

"What functions will you have after the upgrade?" Xia Wan nodded as if she understood but not quite. She didn't understand what energy was and just wanted to know what she would get after the system was upgraded.

[System upgrade: The host can now use points to check the identity of the person they attacked. The system shop will also offer a wider selection of items, and points can be converted into the world's legal tender.]

Xia Wan was almost speechless when she heard the system's answer.

"So, from now on, the points I earn from beating people up will be equivalent to money. How does this exchange work? How is the exchange rate calculated?"

10 points equal one dollar.

Xia Wan glanced at the points in her system. If these were converted into RMB, she would almost be a millionaire.

"You said you could use points to check the identity of the person who was assaulted. Does that mean the person's identity information or just an identity name?"

[It includes the other person's name and a description of the heinous acts they committed.]

"Upgrade, upgrade now!" Xia Wan shouted eagerly, impatient to see the new changes after the system upgrade.

Her eyes gleamed as she looked at the stone; this thing was worth a hundred million points! She was incredibly lucky.

[Okay, host. System upgrade in progress, please wait.]

As the system's mechanical voice sounded, Xia Wan stared intently at the system panel in front of her. It instantly turned a dull gray, losing its original luster and vitality.

The stone placed on the table also instantly lost some of its luster.

However, Xia Wan was relieved to find that the space in the system and the two academies she had previously obtained through the lottery could still be opened and used normally.

She thought to herself, "Thank goodness these functions weren't affected, otherwise it would be so boring."

Xia Wan raised her wrist, glanced at the time, and realized she still had some time before her business was due. So, she decided to take this opportunity to continue her studies at the Traditional Chinese Medicine academy. After all, acquiring more knowledge is always beneficial.

This wasn't her first time entering the Traditional Chinese Medicine Academy. The layout was exactly the same as when she first came. Apart from a tireless robot teacher who always stayed at his post, the rest of the furnishings and decorations exuded a strong sense of antiquity, making one feel as if they had traveled back to ancient times.

Recalling her first visit here, Xia Wan couldn't help but smile slightly. Back then, the robot teacher, upon seeing her, quickly assigned her a daunting task: to read all the books on the left-hand bookshelf. After that, she was completely ignored!

Now, after a period of effort, Xia Wan has completed one-third of the reading and is currently at the stage of memorizing the acupoint chart.
