Yu Yao picked up the phone and saw that it was Yanjing's landline number, and at the same time, he also saw the time, it was half past nine.

Holding the mobile phone and not answering, Yu Yao quickly walked to the door, looked at it from the cat's eye, saw that it was Lin Fengcao, opened the door and let him in.

After closing the door, Yu Yao pointed to Lin Fengcao's mobile phone, said "Special Investigation Bureau", and picked it up.

Sure enough, it was Yang Sihai who called.

"Xiaoyu, about Xu Taiyan's birthday that you want to check, I do have a record here, but I don't know the source, most of it is collected folk information, and it cannot be used as historical materials. I'll tell you first. ”

"It's good to have. ”

"Listen, it's a lunar date: June 13 of the 16th year of Guangxu. ”

"Thank you Ju Yang, I wrote it down. ”

Yang Sihai paused, "You don't need his death date, do you?"

"Huh?" Yu Yao was stunned for a moment, is this still "buy one get one free"?

"Yang Ju, regarding the date of his death, I have collected an old newspaper from the Republic of China, which seems to be the third day of September in 1938. ”

"You know a lot!" Yang Sihai paused, "This is also a rumor date, because Xu Taiyan completely disappeared that day and never showed up again, and then it was rumored outside that he was killed by the Japanese people, and there were even rumors that the body covered with a white cloth was carried out from Gegu Zhai. And some newspapers did report it. However, there has been no conclusive evidence, so it is even more unreliable than the date of birth. And what we record on our side is: the year of death is unknown. ”

As soon as he heard this, Yu Yao suddenly woke up a little, no wonder it was wrong to enter the death day!

Although the result of the complete disappearance and death of the Ghost Eye Gate is the same, it cannot be determined that that day is Xu Taiyan's death day.

At this time, Yang Sihai then asked, "Okay, if you want to help, I'll help." Now I can tell me, why did you ask Xu Taiyan?"

"There's really nothing Yang Ju, I'll tell you everything I can say. ”

Yang Sihai laughed twice, "If you don't want to say it, I can't force you." But Xiaoyu, I have two things to say. In terms of age, I am about the same as your father's generation; in terms of identity, I represent the state department; Mr. Xu Taiyan is a strange generation, and to this day, there are still many confusing places; after so many years, the scope of this is still very wide, and the water is still very deep. I'm very optimistic about you, don't go the wrong way!"

"Yang Ju, what you said made me shudder!"

"You're smart, don't fight me haha. There is a knife on the head of the sharp word, even if you don't talk about anything else, you always have to protect yourself, right? At the critical moment, you still have to believe in the country!"

"I understand that. ”

"People, at different stages, will have different ideas. I can't force you, but I want to tell you, when it comes to big things, you must think clearly. ”

"Thank you, Yang Bureau. I will. ”

"Okay, then I won't say more, feel free to contact me if you have something. ”

"Okay, you hang first. ”

Hanging up the phone, Yu Yao looked at Lin Fengcao, "I asked about my birthday, but Yang Ju also nodded to me." ”

"Do they know about the Vault too?"

"I don't know. However, they certainly have quite a bit of the situation. Mr. Xu Taiyan, and the Ghost Eye Gate······ They just guess, and they are afraid that they can guess what heavy weapons may be left. ”

But if you don't ask them, I'm afraid it's hard to know Mr. Xu's birthday. ”

Yu Yao nodded, "Yes, if we inquire ourselves, we don't know about the Year of the Monkey." I didn't ask him about the house number. ”

"Don't ask, I asked. Lin Fengcao said, "Twenty-nine, twenty-nine, is a two-digit number, definitely not right." ”

"So it seems that we only have the straw of the birthday at the moment. "Yu Yao, "The sixteenth year of Guangxu is 1890, so Mr. Xu only had a son Xu Chang'an at the age of forty. ”

Yu Yao said, called up his mobile phone again, and checked the perpetual calendar, June 13, 1890, and the date of the Gregorian calendar was July 29, 1890.

“18900613，18900729。 You'll have to try both. Yu Yao groaned.

Before Yu Yao's words fell, Lin Fengcao frowned, "July 29, 1890? ”

"Wouldn't it?" Yu Yao was stunned, "Wouldn't it be because the last two digits on July 29 are also 29, which matches the house number, right?"

"No, it's that the overall date feels a little familiar. Lin Fengcao said, immediately picked up his mobile phone, and inquired, "I said! July 29, 1890, was the death day of the great painter Van Gogh, because of mental illness, he shot himself at the age of 37. ”

When Yu Yao heard this, he couldn't help but slap his face:

July 29, 1890, is not only Mr. Xu's birthday, but also Van Gogh's death day! And this 29 is still the house number of Gegu Zhai! Three in one! Therefore, the possibility that the password is 18900729 is extremely high! I must try this first!"

Lin Fengcao nodded again and again, "That's right! This possibility is indeed very large." ”

At this moment, Yu Yao's mobile phone rang, and it was Cai Pengxi calling.

After answering the phone, Cai Pengxi told Yu Yao that during the Republic of China, the old house number of Geguzhai was No. 29. This, as Lin Fengcao said, seems to be correct.

Yu Yao told Cai Pengxi that Xu Taiyan's birthday was inquired, and the mantissa coincided with the house number, so it was completely worth a try!

"Oh?" Cai Pengxi said with a tone of surprise, but then pondered for a moment, and then asked Yu Yao, "What if this is not right?"

"This ······" Yu Yao sighed, "I'm afraid there is really no other way!"

"Don't be discouraged, I'm just going to tell you the worst first. Cai Pengxi said again, "Even if you open the box, your current situation has a long way to go, don't be blindly optimistic at any time." ”

"The old man's hard work, I understand. ”

"It's up to you to decide what to do. Whether you can unpack it or not, give me a call. ”

After hanging up the phone, Yu Yao lit a cigarette, "Jiang is still old and spicy, and you have to be calm when you come to a major event." ”

Lin Fengcao smiled, "Actually, you're not too excited. In this way, let's take a break, have lunch at noon, and then go to the bank branch in the afternoon. If the password is still incorrect, then you can go home. ”

Yu Yao agreed.

At noon, the two had dinner together, and after the meal, they walked around the nearby park for a while before taking a taxi to the bank branch.

It was the salesman who received Yu Yao, Lin Fengcao was waiting in the hall, and he took Yu Yao in again.

"Mr. Yu, it seems that you have really thought about it this time. Before entering the password, the salesman smiled more.

Yu Yao glanced at him, "Even if you can't think about it, there are still two chances!"

"Yes, please. The salesman was very uncomfortable with Yu Yao, and bowed his head and stopped saying a simple answer.

Yu Yao took a deep breath and steadily clicked on the screen to type: 18900729.
