Then Tang Tang suddenly remembered something. With a slightly nervous look on her face, she asked, "Brother Zuo Mu, what means do you think the other side used? How come those numbers appear and disappear from time to time?"
Zuo Mu smiled and voiced his speculation. "It's not that difficult. There's a lot of ink on the market that leaves no trace once written. I guess the other side just used some other small tricks on this basis."
This was nothing new to them.
When Zuo Mu was in the hospital, there were strict requirements for writing medical records. On his first day of internship, his teacher sternly emphasized that he must never use the wrong ink. So he had a particularly deep impression of this.
"I see." Tang Tang nodded thoughtfully.
Zuo Mu didn't focus on this.
From the very beginning, he remembered that the key was the numbers.
Especially the numbers two and four. Faintly, some familiar thoughts would flash through Zuo Mu's mind.
But when he tried to think it through, they all vanished without a trace.
This was really strange.
Could it be that there had been a similar case before?
Thinking of this, Zuo Mu immediately sobered up and stepped on the accelerator.
If this was the way of thinking, he roughly knew how to look for clues.
Tang Tang watched Zuo Mu's suddenly excited expression and felt a bit puzzled. However, she still had blind confidence in Zuo Mu, probably because Zuo Mu had never failed.
Since he had thought of a clue, Zuo Mu didn't waste a single moment. As soon as he got home, he rushed into the study. Tang Tang stared at him outside, but she didn't dare to interrupt Zuo Mu when he was on a roll with inspiration.
Perhaps this was a common problem among all geniuses. Once they got an inspiration, they basically isolated themselves from the world automatically. No external sound could stop their train of thought.
Seeing Zuo Mu like this, Tang Tang felt a bit relieved instead. She wondered what useful clues Zuo Mu would discover this time.
Now the enemy was in the dark while they were in the open. They had no advantage and couldn't figure out the enemy's purpose.
Tang Tang lay in the living - room alone. She hadn't had much rest since she got back yesterday, so she decided to take a good rest. She also picked up her phone to check if there were any messages.
As usual, her phone was flooded with messages from Huang Xiaoli.
Huang Xiaoli didn't know where she had gone for fun today. It was probably with her parents. For Huang Xiaoli, who had been looking forward to a family trip for a long time, she was extremely happy.
But the talkative Huang Xiaoli didn't intend to let Tang Tang off.
She would send a message saying "It's so much fun here" one moment, and then send a picture of mouth - watering food the next, which was really envy - inducing.
After sending a message saying "It's so much fun", Tang Tang fell into deep thought.
At this moment, while being happy for Huang Xiaoli, Tang Tang also saw the happy and brilliant smiles of their family of three.
In the past, Huang Xiaoli had always been disappointed when talking about her parents because her family was too busy. Even her birthday was arranged by her best friend Tang Tang.
Although Huang Xiaoli had never lacked anything materially, in terms of family company, to be honest, the time Huang Xiaoli's parents spent with their daughter was less than the time Tang Gu spent with her.
Seeing this, Tang Tang also missed her father, Tang Gu.
She sent a message to Tang Gu.
"Your daughter has really made a name for herself. She can even solve cases now."
Unexpectedly, she immediately received a barrage of messages from Tang Gu.
"What?"
"That bastard Zuo Mu. It's fine that he's always mysterious and we don't know what he's up to. But you're getting involved too. What if you're in danger?"
Tang Gu, who didn't know the inside story, was originally very happy when he saw his daughter's message.
Since there was a time difference between Europe and China, although Tang Gu was very sleepy, he still forced himself to stay awake and chat with Tang Tang.
"It's nothing, Dad. Don't be so nervous. It's just small cases like lost cats and dogs. It's just being helpful. Please don't be angry."
"Don't lie to me! That kid Zuo Mu never acts in a proper way. He's always busy with these cases. Sweetie Tang Tang, you mustn't participate with him. This kind of thing is very dangerous."
Even through the screen, Tang Tang could feel how anxious Tang Gu was, as if he wanted to fly back immediately.
"Don't worry, Dad. We just take a look occasionally and don't really get involved. So we're actually very safe every day." To prevent Tang Gu from rushing back tomorrow, Tang Tang told a white lie.
However, she was still touched by Tang Gu's concern.
As for today's incident, she thought it better not to mention it for the time being, so as not to worry Tang Gu who was far away in a foreign country for no reason.
"Does my precious daughter have a suitable boyfriend now?"
While most parents and schools oppose puppy love these days, Tang Gu did the opposite. Due to his job, he was exposed to foreign cultures more often and had a more open mind.
The first face that came to Tang Tang's mind was actually Zuo Mu's.
She was shocked by her own thought and quickly replied, "No, no, no."
Tang Gu on the other end was originally just joking. Tang Tang's hasty denial made it seem like she was trying to cover up something.
This realization made Tang Gu shed a tear.
Was someone trying to court his little daughter?
With Tang Tang's smart and mischievous look, Tang Gu was really worried.
Tang Tang chatted with Tang Gu about her recent situation casually, and Tang Gu also told her what he had seen and heard this time.
Seeing that it was getting late and Zuo Mu still hadn't come out, Tang Tang went into the kitchen to check the ingredients. She decided that with her cooking skills, the only thing she could make was fried rice with eggs.
The rice and eggs were ready. To her surprise, it was quite a success on the first try.
The golden, oily egg pieces, the green onion leaves, and the plump white rice were extremely appealing.
Tang Tang kept the rice warm, planning to wait for Zuo Mu to eat together.
Normally, Tang Tang would have called Zuo Mu already, but in this special situation, she decided not to. What if Zuo Mu was just about to figure out the key point?
After a while, there was a click sound from the door of Zuo Mu's room. It was a sign that Zuo Mu was unlocking the door and coming out.
Tang Tang watched Zuo Mu appear in her sight. His expression was more solemn than ever.
Tang Tang's heart sank.
"We may not be able to handle this on our own." Zuo Mu stated the conclusion.
If it was someone else who said this, Tang Tang might have just rolled her eyes. But the one who said it was Zuo Mu! Even when handling cases last time, she hadn't seen him look this solemn.
Tang Tang was also affected by this mood and didn't even dare to breathe loudly.
It wasn't until the sound of running water came from the bathroom that Zuo Mu washed his hands and slowly came out.
Wow, he really was as elegant as a jade tree.
Tang Tang sighed in her heart.
