At this point in the wee hours of the morning, there are two trains at Shanghai Railway Station. One train is the train to Nanjing that Lin Jiangbei said to the taxi driver at 1:50 before; The other bus went to Ningbo via Hangzhou at 2:15 p.m.

Lin Jiangbei rushed over with Liu Xuan, in fact, he planned to let Liu Xuan take the 2:10 train and take the 91-style cipher machine back to Hangzhou. He said that to the taxi driver before, mainly just in case.

One of the reasons why Liu Xuan was asked to bring the 91-style cipher machine back to Hangzhou was because of the telecommunications class in Hangzhou, where the cryptography experts and radio experts of the intelligence department were concentrated. Bringing the 91-type cipher machine back to Hangzhou, the cryptography experts and radio experts of the intelligence department can better and faster study the 91-type cipher machine.

Of course, this reason is only a secondary one. The main reason is that Lin Jiangbei wants to hand over this 91-style cipher machine through Zhou Fengshan's hand.

When seizing this 91-type cipher machine, Lin Jiangbei thought very clearly, and unlike the previously seized cipher book, the importance of this 91-type cipher machine can even be said to be equivalent to several Japanese divisions.

Lin Jiangbei remembered that in the previous life, the US military was reluctant to let Qian Xuesen return to China, saying that Qian Xuesen's value alone was equivalent to the strength of five reinforced divisions of the United States.

So now, the importance of this 91-style cipher machine in Lin Jiangbei's eyes is almost no less than that of Qian Xuesen, Qian Lao, who was preparing to return to China in the fifties. Because at present, this 91-style cipher machine represents the highest level of Japanese radio cipher. As long as you understand the principle of the 91-style cipher machine, you can basically directly decipher the highest level of Japanese ciphertext.

Then it also means that when China and Japan are at war in the future, China can completely rely on cracking Japan's secret telegrams to grasp the dynamics of the Japanese army, so as to carry out targeted deployment, even if it is only to play a role in a key battle, then at least one or two more Japanese divisions can be eliminated.

And that's just on the Chinese side.

And once China shares the 91-style cipher machine with the United States, how much damage will it cause to the Japanese army once the movements of the Japanese army are mastered through the 91-type cipher machine with the powerful military strength of the United States?

Therefore, in this sense, Lin Jiangbei believes that this 91-style cipher machine is equivalent to several divisions and regiments in Japan, which is not an exaggeration.

With Lin Jiangbei's personality, in the face of such an important 91-style cipher machine, how could he bypass Zhou Fengshan, who had always been kind to him and take care of him, and directly let Liu Xuan run to Nanjing and send it to Duan Yinong?

Of course, even if Zhou Fengshan's support and care for Lin Jiangbei are not considered, Lin Jiangbei will not do stupid things to bypass Zhou Fengshan, and in this regard, the Intelligence Department once had a very famous negative example.

The protagonist of this negative example is the previously mentioned Wang Guanghui, Chen Zui's boss, Wang Guanghui of the Investigation Brigade of the Songhu Garrison Command, who is currently in charge of public security in the Shanghai area.

Wang Guanghui used to be Duan Yinong's favorite general, so Duan Yinong sent Wang Guanghui to Shanghai to serve as the first head of the Shanghai Special Zone of the Intelligence Department. But Wang Guanghui didn't sit in the position of mayor of Shanghai for a few days, and he did a particularly stupid thing.

It was still the summer of 1932, when the police in the French Concession in Shanghai stumbled upon a material on part of the Red Army's deployment and equipment, and Fan Guangzhen, a staff member of the Intelligence Department who had been stationed in the French Concession, realized that this was an important piece of information, so he handed over the material to Wang Guanghui.

According to the normal procedure, Wang Guanghui wanted to hand over this information to Duan Yinong, but Wang Guanghui didn't know if it was because of the water in his brain or something that day, and he actually thought of sending this material directly to Principal Chang.

At that time, Principal Chang was in Jiangxi to "suppress red", because Wang Guanghui had worked in the navy during the Northern Expedition, so he found a warship through his connections, went down the river, and prepared to go to Lushan, Jiangxi Province to personally send the information to the principal. As a result, as soon as he walked on the front foot, Duan Yinong on the back foot got the news. So Duan Yinong directly found a plane and flew to Jiujiang.

It turns out that you take a steamer, I take a plane, and see who can run fast! When Wang Guanghui landed from Jiujiang with great interest, "thinking that a great bird was coming", he was greeted by Duan Yinong's pistol.

"Shake the wit" with Boss Duan, obviously there will not be any good results. Wang Guanghui's toss and turn, in exchange, was immediately removed from his post and imprisoned.

However, Duan Yinong is a person who loves talents after all, he is not too difficult for Wang Guanghui, and he will not be as knowledgeable as his subordinates, so he quickly released Weng Guanghui again, and made Weng Guanghui the captain of the reconnaissance brigade of the Songhu Garrison Command.

It is precisely because of this lesson that no matter how stupid Lin Jiangbei is, he will not do anything to directly cross Zhou Fengshan and Du Chenghu and hand over this 91-style cipher machine directly to Duan Yinong. Although Duan Yinong may not really be angry with him in that way, in Duan Yinong's mind, wouldn't he have become a person like Wang Guanghui?

Of course, Liu Xuan is also very clear about the twists and turns in the middle. So when Lin Jiangbei explained to him in Gucun Xia Chuan's room and asked him to send the 91-style cipher machine back to Hangzhou, he didn't have the slightest objection.

After stepping on the railway station square, Lin Jiangbei and Liu Xuan began to act separately. Liu Xuan went directly to the Shanghai Railway Station Police Station and revealed his identity as a member of the Hangcheng Station of the Intelligence Department to the police station, and then was arranged by the police of the Railway Station Police Station to the VIP room, and after the train entered the station, he was directly sent to the sleeper room of the first-class carriage.

Lin Jiangbei promised Colonel Price of the Fourth Expeditionary Regiment of the US Marine Corps that he would go to investigate the scene of the death of the old drunkard tomorrow, so he still had to stay in Shanghai, so he could not reveal his identity to the police at the Shanghai Railway Station Police Station. He went to the ticket window to buy a second-class ticket and waited in the waiting room.

At 2:05, Lin Jiangbei caught a glimpse of the VIP room, where Liu Xuan was carrying a suitcase and entering the railway station through a special passage under the escort of two plainclothes personnel. So he also stood up with his train ticket and lined up at the entrance of the station.

Three minutes later, the entrance began to be released, Lin Jiangbei followed the passengers into the station, and saw Liu Xuan standing in the position of the first-class car, talking and laughing with the two plainclothes officers.

At 2:20 a.m., the train from Nanjing slowly entered the Shanghai Railway Station. Liu Xuan shook hands and said goodbye to the two plainclothes officers, and then boarded the first-class car.

At 2:25, under the watchful eye of Lin Jiangbei, the train slowly left Shanghai Railway Station and headed for Hangzhou. Through the window, Lin Jiangbei saw Liu Xuan gesture to himself that everything was going well.

Lin Jiangbei nodded with a smile.

With Liu Xuan's skills, coupled with the protection of the first-class carriage with special railway police, it should not be a big problem to arrive in Hangzhou safely.

So he took his ticket and turned around and walked out of the station.

For him, the main task next is to think about how to help Colonel Price find the real murderer of the old drunkard.
