When he casually flipped through the dilapidated and yellowed "The Family of Gold Powder" for about three minutes, Chen Lei suddenly discovered the mystery in it, which can be said to make him feel like a treasure, as if Columbus had discovered a new world.

Chen Lei, who was still at a loss, immediately lit up, and felt that the old man was thousands of miles away in Beiping, and he deliberately sent a telegram to his apprentice Zhao Agui to send this old "The Family of Gold Powder", which must have his intentions.

Chen Lei, who sat up from the bed, flipped through this famous book written by Zhang Hatshui many years ago again, and he counted it carefully, and there were a total of nine pages folded in the lower right corner of about half a centimeter.

Not only that, in these nine folded pages, there is a pencil circle of a word, according to the order of the page number, the nine words are composed of: Xintongfu Hotel in the third district of Beiping.

Before the Anti-Japanese War during the Republic of China, Beiping as a special city, divided into six inner districts, five outer districts and eight suburbs, after the 77 Incident, Beiping fell, and the puppet regime that ruled Beiping disrupted the original inner districts, outer districts and suburbs, divided into 16 districts.

Thinking about it again, Lao Fang is now on a business trip in Beiping, and this address is very likely to be Lao Fang's current residence in Beiping.

After thinking of this, Chen Lei immediately couldn't hide his excitement, and immediately stood up, his bed cheered, at this time, he was like a child in a kindergarten.

However, after less than a minute of joy, Chen Lei, who was happy, thought about it, although he learned about Lao Fang's residence in Beiping, next, how would he get in touch with Beiping.

If you write a letter and mail it, it is a long way from Shanghai to Beiping, and it is estimated that the letter has not yet arrived, and the old party has already returned to Shanghai.

If you want to shoot a telegram, you can only do it through the post office, the number of words in the telegram is relatively small, and some of the content is not suitable for the telegram.

In the end, Chen Lei had the mentality of giving it a try, and decided to make a long-distance phone call to get in touch with the old party in Beiping, and he felt that compared with the above two contact methods, it was more convenient and faster to call.

Of course, Chen Lei can't borrow a private phone to make a call, he needs to walk about ten minutes away from his residence, a public phone booth located on Xiafei Road to make a call, not only is it convenient to speak, but also it is not easy to reveal his identity.

According to the memory left in his head, Chen Lei took out ten phone coins from a drawer at the bottom of the bedside table in the bedroom.

The coin is 18.5 mm in diameter, 1.4 mm thick, weighs about 3 grams, and is made of copper-steel alloy.

On the obverse of the phone coin, there is the French word "Shanghai Telephone Company" and an engraved telephone pattern, and on the reverse side is the Chinese and French words "can make a call".

According to the price of telephone coins in the French Concession at that time, one telephone coin was about five dimes, and the price of two telephone coins was one silver dollar, that is to say, ordinary people living in Shanghai Tang, let alone installing private telephones at home, even making public telephones on the side of the road, could not afford to make a call.

Fortunately, for Chen Lei, who has a decent income, he can still afford to make a public phone on the side of the road.

What's more, at the telephone company located in the French Concession at that time, he only needed to pay enough money at the counter of the business hall to buy phone money, and did not need to register with his real name, which was the most important point for him.

In addition, using the coin-operated public telephone on the side of the road, you only need to vote one phone coin to make a call in the city, and you need to vote two phone coins for domestic long-distance calls.

So, Chen Lei took two phone coins, hurriedly walked out of the house, and spent about ten minutes in front of a public telephone booth on Xiafei Road.

At this time, it was almost half past seven o'clock in the evening, and the flow of people and vehicles on Xiafei Road was relatively large, and it was a relatively prosperous commercial street in the French Concession.

Although there was no one in the public telephone booth numbered No. 4 Xiafei Road in the French Concession before Chen Lei arrived, he did not rush in, but stood outside the shared telephone booth and waited for about two minutes, until there was no suspicious person within a radius of 100 meters, and then he pushed open the door and entered the shared telephone booth.

Entering the shared telephone booth, Chen Lei saw that there was a fixed back-supported No. 553A telephone, and next to it was a Glen No. 8A coin box.

After looking at it twice, Chen Lei took out two telephone coins from his jacket pocket and put them into the Glen No. 8A coin box in front of him, then picked up the telephone receiver and first called the telephone bureau wiring room in the French Concession in Shanghai.

"Hey, hello, help me answer the call from Tongfu Hotel in the third district of Beiping." After connecting it, Chen Lei lowered his voice and said to the operator of the Shanghai French Concession Telephone Bureau on the other end of the receiver.

Immediately afterwards, the sweet voice of the female operator came from the telephone receiver held by Chen Lei in his left hand: "Okay, sir, please wait a while, and I will receive the Tongfu Hotel in the third district of Peking for you immediately." ”

After waiting for about twenty seconds, a slightly hoarse baritone voice came from the telephone receiver held by Chen Lei in his left hand, and asked: "Hey, I am the Tongfu Hotel in Beiping, where are you?" Who to call for this call? ”

Hearing the voice coming from the telephone receiver, it was a straight Beijing dialect, Chen Lei replied after a long sigh of relief: "Hello, I am Wang Lei, a reporter from Shanghai Tang's "Declaration", and I want to find Mr. Feng Qiuyuan Feng, who lives in your hotel and is also from Shanghai. If Mr. Feng is here, can you let him answer the phone, I'll talk to him. ”

However, all those engaged in underground intelligence in Shanghai, whether they are underground parties, military commanders, or central commanders, basically use pseudonyms, and very few people disclose their true identities to engage in intelligence work.

In fact, Chen Lei's name is also a pseudonym, but it has been made public in Shanghai, and he has been calling it this way in front of the public.

In terms of external affairs, in order not to expose the pseudonym "Chen Lei", Chen Lei had to make up a pseudonym "Wang Lei" for himself, and the same is true for the old party, the two of them discussed that in addition to the way of meeting and communicating, they both took another pseudonym to call each other.

Chen Lei's other pseudonym is "Wang Lei", and Lao Fang obtained another pseudonym as "Feng Qiuyuan", in order to achieve the purpose of hiding people's eyes, only the two of them know each other's pseudonyms.

Subsequently, Chen Lei, who was standing in the public telephone booth on Xiafei Road, waited for about a minute, and then heard a familiar voice on the other end of the phone, asking: "Hello, Mr. Wang, I'm Feng Qiuyuan, long time no see!" I sent you a telegram to Shanghai a few hours ago today, and now, should you get it? ”

Chen Lei didn't have time to think about Lao Fang's inquiry, so he replied without thinking: "Yes, Mr. Feng, I took the telegram and left, and the book you gave me is also in my hand." ”

After listening to Chen Lei's answer, the old man went straight to the point and said, "Mr. Wang, the good news you sent to your hometown in Shancheng this morning, my hometown in Shancheng has already asked someone to tell me. I feel that this good news is gratifying, but it is not appropriate to publicize it to the outside world at present. Three days later, you're telling your mother's house in Yamashiro. ”
