"Yeah." With Xu Tian's situation, it would be of no use to go to Mr. Tang. It would be better to let him rest in peace and recuperate.

The sudden disappearance of the head of the Tang family has plunged the entire family into an unprecedented panic. Some people even maliciously speculated that Tang Bingyan was dead and that the Tang family would soon be in chaos.

As for the high-ranking officials of the Tang family, who were already quick-thinking, they were even more active in making some small moves in secret. Fortunately, before Mr. Tang fell down, he had to forcefully force all insiders to block the news, otherwise the Tang family would have been torn apart by now.

But blocking the news is not a long-term solution. If Tang Bingyan's whereabouts are never found, the Tang family will still face disintegration.

At present, the Tang family seems to be calm on the surface, but in fact, there is an undercurrent, as if it is the calm before the storm, but I don't know who will break this tranquility.

It was impossible for Tang Bingyan not to know that her departure would have a huge impact on the Tang family, so Xu Tian was not sure of his previous judgment.

Could it be that a strong external force really intervened and took Tang Bingyan away?

"Mr. Xu, I still have a lot of things to deal with here, so I'm leaving first. Don't worry too much. If there is any news, I will call you immediately." A Wei comforted Xu Tian a few words, and then

Left in a hurry.

Xu Tian stood in the living room for a while, then went upstairs to Tang Bingyan's study.

He doesn't have any clues now, and can only hope to find some clues in her study.

Tang Bingyan's study is in a mess, the antique cabinet is empty, and the floor is full of broken porcelain pieces that haven't had time to be cleaned. She probably doesn't allow servants to come in to clean it.

Xu Tian glanced at the furnishings on the desk and first noticed the phone in the corner. The receiver was hanging on the side but did not ring. It was probably because Tang Bingyan broke the phone when she lost her temper.

In fact, nowadays, mobile phones are used so frequently that no one knows how to use landline phones. But I don’t know why Tang Bingyan always keeps this phone in her study.

Xu Tian stepped forward and picked up the hanging receiver and put it to his ear. Sure enough, it couldn't be used.

However, although the phone was broken, the display screen was still on. Xu Tian glanced at the incoming call reminder and found an unfamiliar number that had called many times.

In fact, this phone is rarely used. It is only used by the servants in the villa when they encounter urgent matters and need to consult Tang Bingyan. Therefore, even if there is a caller ID, only the number inside the villa will be displayed.

But Xu Tian had never seen this number before, and its components didn’t look like domestic numbers.

The time of the last call also happened to be before Tang Bingyan lost contact.

Xu Tian took out his mobile phone and tried to dial the number but couldn't get through.

He immediately called Yan Qingxue.

"What's wrong?" Yan Qingxue is handling the contract in the company.

"Can you help me look up a number?" Xu Tian said the numbers straight to the point.

"What is this?" Yan Qingxue frowned when she heard it, "It's not from China, nor does it seem to be from around Asia-Pacific. Where did you know this number?"

Xu Tian: "Check it for me."

"Wait a minute." Yan Qingxue held the phone between her ears and shoulders and typed on the keyboard skillfully.

When she worked for that scumbag Xu Rixin, she mastered the search skills skillfully. In addition, she had minored in related majors because of her interest in college, so checking a phone number was not a problem for her.

Xu Tian felt restless listening to the "crackling" sound of keyboard tapping.

"Ah..." After a while, Yan Qingxue let out an exclamation.

"What happened? What did you find?" Xu Tian asked.

"It can't be found. This is not a phone number at all. It cannot match the number range of any country, and it is not a deliberately encrypted number." Yan Qingxue concluded, "In short, this is just a series of strange numbers."

"Not a phone number?" Xu Tian was shocked.

How is this possible?

This number made several calls to Tang Bingyan, and Tang Bingyan answered every time.

But she has never taken the initiative to broadcast this number. It seems that the owner of this number has been contacting her unilaterally.

With Tang Bingyan's strong personality, it was impossible for her to tolerate one-sided contact, but she did not take the initiative to contact the other party even once.

"Xu Tian, ​​did you remember it wrong? Yan Qingxue's voice sounded again, "If we add another digit, maybe we can get through it."

"Yes, this must be a phone number. If you have time, keep checking it for me."

"Okay then, I'll try again."

Putting down his cell phone, Xu Tian walked around Tang Bingyan's study again.

He always felt that this number might be related to Tang Bingyan's disappearance, but now he didn't have a clearer clue.

So he planned to continue looking for clues in the study.

There were Tang Group documents in the drawer, most of which were contracts and financial statements. Xu Tian flipped through them roughly, but found no useful clues.

After checking the desk, the man who found nothing walked back to the bookcase.

Initially, he thought that the bookcase had not been affected by Tang Bingyan's anger, but when he got closer, he discovered that the books on it had been disrupted, and some were upside down, as if they had been stuffed in in a hurry.

Xu Tian's eyes passed over these books one by one, and he took out the books that he felt had problems and flipped through them for inspection, but he still found no useful clues.

Just when he was about to put the book he was holding back into the bookcase, he suddenly found a corner of the cowhide file bag exposed on the inside of the bookcase.

Only then did Xu Tian discover that there was a gap between the book and the wall panel inside the book, and this gap was enough to accommodate an A4-sized file bag.

He quickly moved away the books that were blocking the outside and took out the file bag inside.

This is an ordinary portfolio, but there is an "x" marked with a red marker in the upper left corner.

Xu Tian couldn't wait to open the file bag and found that there was only a piece of paper inside, and the number written on the piece of paper was exactly the number he just found.

Now Xu Tian can be sure that this string of numbers is very important to Tang Bingyan, but what makes him even more troubled is that there is only a string of numbers, which does not allow him to find out the reason for Tang Bingyan's disappearance.

Because he discovered the secret of the bookcase, Xu Tian simply moved all the books on it.

When the bookcase was emptied, he was surprised to find that there was a groove on the inside of the bottom wall panel, and inside the groove was a locked rectangular box.

Xu Tian bent down and took out the box. He tried two sets of passwords that Tang Bingyan might use, but failed to open the lock.

There must be something important in this box, otherwise it wouldn't be hidden inside the bookcase with a combination lock.

Moreover, every time the password lock is entered incorrectly, it will be locked for a certain period of time.

Xu Tiancai tried three times, and the lock time was already as long as two hours.
Chapter completed!
