I wonder how many attribute points the serum of a mid-level mutant zombie can add? "How is the analysis of the metadata information you mentioned?"

Ning Yu still remembers the audio content that was analyzed from the low-level serum last time. The content contained a lot of information.

"I studied the purification method first, which is relatively simple."

"And in the serum you gave me this time, there is a different metadata sequence, but its encryption method has also changed."

"Not only that, but they also used a more complex encryption method and mixed it into the normal sequence. If I hadn't figured out the encryption salt used in the low-level serum, I'm afraid I wouldn't have made any progress for a long time."

It was impossible for Lin Hao to forget this incident. He then said some terms that Ning Yu could not understand, such as "salt", "N-times encryption", "rainbow table" and so on.

But the general meaning was that it would take some time, but the information hidden in the low-level serum helped him.

Ning Yu always felt that the clues hidden in the low-level serum to the mid-level serum seemed to have been buried intentionally, waiting for someone to discover them.

"That's about it. We may have to wait a little longer, but my intuition tells me that there must be a bigger secret hidden inside."

Ning Yu nodded. There was no point in getting anxious about this kind of thing, but she thought of another problem.

If she had not saved Lin Hao at the beginning, there would not have been so much progress today, and she would not have been able to obtain more secrets related to the virus so quickly.

But all this happened somewhat coincidentally, as if an invisible hand was guiding her onto this path.

She looked at Lin Hao's serious expression and didn't seem to think so much. Only Ning Yu, who had experienced everything, would have such doubts.

Her knife, the system on her body, and the experiences she has gone through, give her a feeling of being led by fate.

Ning Yu shook her head, perhaps it was just an illusion.

"That's about it."

Lin Hao had finished speaking now.

After the two exchanged information, Ning Yu took the serum, and the two left the empty apartment in the same way.

This time there is at least a new development. If there is a next victim, Ning Yu can know it in advance and even take action in advance.

That night, the night was exceptionally quiet, with a drizzle falling outside the window.

Ning Yu was playing the piano out of boredom. This time she didn't play jazz, but a relatively quiet and lonely classical piece.

It is Bach's Concerto in D minor BWV974-II.

Ning Yu felt that this song would be extremely suitable if played on a rainy night.

In her previous life, she had a favorite pianist who played this piece of music. Only that person could convey that unique feeling of loneliness and solitude.

The only drawback is that this famous pianist likes to hum softly while playing the piano, so much so that some people commented on him like this:

“In Gould’s concerts, you can even hear him play the piano.”

And now, Ning Yu couldn't help but hum along, she didn't even realize it.

Shen Yiyue was listening right next to them with Shen Qianqian, but Shen Qianqian was not paying attention. Instead, she was reading a girls' comic next to them.

Shen Qianqian was a little kid and it was difficult for her to concentrate on such a quiet and profound piece of music. After a while she became sleepy and couldn't help yawning.

Then he suddenly covered his mouth, feeling that this seemed impolite.

I secretly glanced at my sister and found that she was listening attentively and didn't notice my actions at all.

She shook her head slightly. Her sister was indeed hopeless. She had fallen in love with Sister Ning Yu who lived at the entrance of the village.

"Sister, I'm a little sleepy. I'm going to bed first."

She decided not to be a light bulb here and leave her space to these two people.

Shen Yiyue looked at her sister, only turned back for less than a second, nodded, and turned back to listen.

Shen Qianqian felt that her sister had been so perfunctory that she simply stopped pretending, and she developed a sense of grievance that "I am redundant".

Really, a sister who is married off is like water spilled out! She went back to her room angrily, and the sleepiness she had just heard disappeared.

"Does it sound good?"

Ning Yu turned around to look at Shen Yiyue and found out that Shen Qianqian had already returned to her room.

"It sounds good! Everything Xiaoyu plays sounds good~"

She walked forward and suddenly sat next to Ning Yu.

There was enough space on the small piano bench, but it became a little full with two people sitting on it.

Ning Yu moved to the left. I didn't understand what she was going to do, but I decided to make room for her.

"Can you teach me?"

Shen Yiyue turned her pretty face and looked at Ning Yu with expectant eyes.

There was still a faint blush on her face from taking a shower, and her bright watery eyes were twinkling with stars.

This is really hard to refuse, but Ning Yu had no intention of refusing.

She smiled and said, "Okay, how about I teach you Little Star today?"

"Um!"

Shen Yiyue nodded. Actually, she could teach anything.

She took Shen Yiyue's left hand and placed it on the bass area.

"Your left hand plays the accompaniment."

"The right hand plays the melody."

Ning Yu also took her other hand and placed her thumb on the middle C.

The two of them sat close together, one teaching patiently while the other learned intentionally or unintentionally, their hands constantly touching and intertwining, and they looked very close.

Although Shen Yiyue's fingers were a little clumsy, she was still able to learn such a simple piece of music easily. She just stumbled when connecting her left and right hands.

However, Ning Yu was still very patient and asked her to keep slowing down the speed until her left and right hands could play together, and then speed it up again.

Shen Yiyue didn't really want to learn piano, but at this moment she was also moved by Ning Yu's seriousness: No one in the world can refuse to teach you something seriously, right, little silver-haired cutie? It wasn't until Shen Yiyue could play 6 phrases fluently that Ning Yu stopped and said:

"That's all for today. If you want to learn, you have to practice often."

It seemed like she really wanted to teach Shen Yiyue a lesson.

"Oh yeah!"

Ning Yu took another look at Shen Qianqian's closed door, then took out the two bottles of serum that Lin Hao had just handed to him today.

"It's time to take your medicine, Dalang."

She made a joke that Shen Yiyue couldn't understand.

Shen Yiyue was still immersed in the happiness of being taught by Ning Yu. She didn't expect her to suddenly take out two bottles of serum. Her expression suddenly froze.

"It's still the same old rule. I'll drink first. If there's no problem, you can drink later."

Ning Yu said to her, and while speaking, she had already opened the cap of one of the bottles and drank it down in one gulp.

Still the same as before, no taste.

Ning Yu was fully prepared. She expected that she might faint, have a fever, or receive some additional prompts from the system.
