Immediately, Ye Wanwan wrote down the phone number.

This phone number is special and does not look like a domestic call.

After hesitating for a moment, Ye Wanwan used her mobile phone to dial this strange phone number.

However, the busy sound on the other end of the phone completely made Ye Wanwan's heart sink into frost.

Not long after, Ye Wanwan dialed Ye Mufan's mobile phone.

"What for?" Ye Mufan asked.

"Brother, help me check a phone number...... Ye Wanwan went straight to the point and reported the number to Ye Mufan.

"What kind of number is this, so weird...... It's not like domestic, and it's not like a few neighboring countries...... And such a phone number? Ye Mufan's voice was surprised.

"Help me find out." Ye Wanwan said.

"Wait, don't hang up yet." After Ye Mufan finished speaking, he immediately turned on the computer and entered the phone number.

"I'll lean on ......" After a while, Ye Mufan's exclamation came.

"Found?!" Ye Wanwan looked stunned.

"Uh...... didn't ......" Ye Mufan said: "Your phone does not belong to any country at all, and it is not a virtual number, this number does not exist at all!" ”

"Doesn't exist?" Hearing Ye Mufan's words, Ye Wanwan frowned deeply, and immediately checked the landline in the study again.

And this string of strange phone numbers, not only once dialed the landline phone in Si Yehan's study, but at least five times, and every time, Si Yehan answered in seconds, as if he had been staying in the study and waiting for this call, and on the dialed phone display, there was no record of the existence of this string of calls.

In this case, the phone number must exist...... And, in terms of Si Yehan's character, unless he can't get through, it's absolutely impossible to stay in the study every day and passively wait for the call to come in......

In other words, this phone call can only be answered, and cannot be actively dialed......

"Wanwan, you can't get through this phone at all, besides, how can there be such a phone number, did you give the wrong ......" Ye Mufan's voice came out.

"I see...... You continue to check it for me, the phone must be there. After speaking, Ye Wanwan hung up the phone.

At this moment, Ye Wanwan was sitting in Si Yehan's study, full of emotions.

I don't know why, Ye Wanwan's heart is more and more convinced, Si Yehan's disappearance must be inextricably linked with this strange phone call, perhaps, it is not completely impossible to disappear because of this phone call......

Just as Ye Wanwan was pondering, she glanced out of the corner of her eye, but she saw a metal briefcase at the foot of the bookcase, and there was an obvious code name "Y" engraved on the briefcase.

Ye Wanwan got up, picked up the briefcase with his hand, and after looking at it, he found that there was a lock on the briefcase, and a password was needed to open it.

Ye Wanwan's gaze fell on the inexplicable letter code on the briefcase, and a trace of doubt appeared in her eyes.

What do the three letters "y" represent?

Ye Wanwan's eyes flashed, and the first reaction in his mind was the pinyin abbreviation of his surname and first name.

The abbreviation of Ye Wanwan happens to be Y.

This...... Is it just a coincidence?

Ye Wanwan's fingers clenched slightly, and she immediately tried to open the briefcase.

It's just that Ye Wanwan tried several sets of passwords, but she couldn't open the briefcase.

Almost instinctively, Ye Wanwan felt that the content of this might be related to herself......
