But here she was far worse treated than she was in Berlin, she was not welcomed by her boss, Manne Siegbahn, and she felt that she was completely isolated from the scientific research infrastructure, unable to inspire intelligence.

Soon after, her nephew, Otto Robert Frisch, came to Stockholm for Christmas and found herself reading a letter from Hahn describing the astonishing incident of using neutrons to act on uranium and discover that the product had barium radioactivity.

Together with Frisch, Liser Meitner theorized the results of this experiment and published it in the January 1939 issue of the journal Nature, in which Liser Meitner and Frisch proposed a new concept in physics—a new class of nuclear reactions—fission.

In this little article, which is just over a page, they paint a basic picture of uranium fission.

Later, Meitner experimentally verified the fission.

Meitner and Frisch came up with the idea of fission while walking in the woods.

The total mass of the fissioned nucleus is smaller than that of the uranium nucleus before fission, and this small difference in mass is converted into energy.

Meitner used the equation of Einstein's theory of relativity e=mc^2 to calculate the energy of 200 million electron volts released by each fission nucleus.

In this way, Meitner laid the foundation for atomic energy.

"The Germans are working on nuclear fission, the United States is working on nuclear fission, the Soviets are working on fission, and Tokyo is working on experimental Liezer Meitner's theory of nuclear reaction-fission." Yamada said, looking at the photo on the profile.

"This man is in Norway now." What Zhou Lin meant in his words, it is impossible for us to go to Norway, do we have to travel again?

"A lot of institutions are looking at the data from the Meitner nuclear fission experiment. A Soviet agent paid a huge sum of money to buy off a man close to Liser Meitner to copy data from Meitner's nuclear fission experiment. However, when the Soviet agents made a detour to return to the Soviet Union via Harbin, the Soviet agents were killed by German agents, but the data on the Meitner's nuclear fission experiment were missing. Yamada said.

"That is, the data of the Meitner nuclear fission experiment was entrusted to someone else before the Soviet agent died, so that he could bring it into the Soviet Union." Kobayashi said.

"No, there is now a rumor on the black market in Harbin that someone has released the wind and sold the data of the Meitner nuclear fission experiment for a million dollars." Yamada said.

"Then Harbin is not a spy city now?" Kobayashi said with a smile.

Zhou Lin said with a smile: "It seems that the director of the agency wants us to join in the fun." ”

"That's right! Harbin is a city where espionage is rampant. There are spies from all over the world. Now, thanks to Meitner's nuclear fission experiments, the number of spies has more than doubled. However, spies from various countries have information about our Japanese spies. Yesterday, two agents of the imperial army were killed in Harbin. Now in Harbin, agents are killed every day. For this reason, the base camp has decided to let you enter Harbin and look for opportunities, no matter what means, to try to grab the data of the Meitner nuclear fission experiment. ”

Kobayashi looked at Yamada: "Let me go?" I'm already semi-public. ”

"You two are bright and dark, Kobayashi-kun is a semi-public agent, so you will let them know that the imperial army is coming. And Zhou Lin is acting in the dark, unconsciously by others. Yamada took out the plan that had been made by the base camp and made it clear to them how to proceed.

Xiao Lin looked bitter, this is the rhythm of death!

Yamada said to Kobayashi: "After you pass, the Harbin Gendarmerie and the Special High School will cooperate with your actions, and you will live directly in the Harbin Gendarmerie." ”

As soon as he heard that he lived in the gendarmerie, the bitterness on Kobayashi's face disappeared.

"If Zhou Lin needs help in the operation, you are responsible for contacting the imperial army in Harbin and giving Zhou Lin full support. You are in contact with telegrams, dead mailboxes. ”

Zhou Lin understood the plan and asked, "How do we go?" ”

Yamada said to Kobayashi: "Tomorrow you take a military plane and fly directly to Harbin." ”

"Yes," Kobayashi said, having to accept the order.

Yamada said to Zhou Lin: "If you go to Tianjin and fly directly from Tianjin to Harbin, you will enter Harbin as a wealthy merchant in Tianjin to buy leather goods." ”

Xiao Lin smiled: "It's going to be a hot day soon, are you going to buy leather goods?" ”

Zhou Lin replied: "Only at this time can you get cheap skins in Harbin." It's the doorway of business, you don't understand. ”

Xiao Lin thought about it, Zhou Lin was right, winter into summer goods, summer goods, summer into winter goods, this is the only way to buy cheap goods from people who are eager to cash out.

After Zhou Lin and Xiao Lin agreed on the frequency and password of the radio contact, they immediately returned to the dock and told Xiangjun about the situation.

Xiangjun immediately went to Yulan, their radio station could not be used, and it was easy to be locked by the Japanese pseudo monitoring system, so it was still the old way.

When the third in Yan'an received Zhou Lin's telegram, he immediately smiled.

The day before, Yan'an received an urgent request for help from the Soviet Union, and the Soviets hoped that Yan'an would send people to get the data of the Meitner nuclear fission experiment at all costs.

The Soviet Union also offered that if Yan'an could help get data from the Meitner nuclear fission experiment, the Soviet Union would assist Yan'an with a division of Soviet-style weapons.

For Yan'an, which lacks weapons, this is a very tempting condition.

Three has notified the Northeast Bureau to use all available conditions to join the operation to compete for data from the Meitner nuclear fission experiment.

However, Yan'an also knows that in Harbin, it is very difficult to get the data of the Meitner nuclear fission experiment.

Now, Yamada actually sent Zhou Lin to Harbin, so Yan'an's chances are one point bigger.

Therefore, Order No. 3: Zhou Lin, Xiangjun, Yulan, and Li Xiang all entered Harbin.

Li Ziqiang stayed behind in Mingzhu, because Mingzhu also needs people.

After Zhou Lin received Yan'an's order, he immediately asked the bald head to select twenty reliable old men and follow him to Harbin, led by the bald head.

In the evening, Zhou Lin came to the statue of the fisherwoman and connected with Yang Kun.

Zhou Lin told Yang Kun about Yamada sending him to Harbin.

After Yang Kun received the news, he asked Zhou Lin to go to the dead mailbox for two hours to get the letter.

Then, Yang Kun left in a hurry.

Two hours later, Zhou Lin and Xiangjun came to the dead mailbox and got the secret letter.

Zhou Lin Xiangjun returned to the dark room and translated the secret message.

It turned out that the U.S. government had also sent a telegram to Chongqing asking for help.

It is hoped that Chongqing will conveniently send personnel to Harbin to take advantage of the geographical advantages and strive to grab the data of the Meitner nuclear fission experiment.

The U.S. government promised that if China helped the U.S. obtain data from the Meitner nuclear fission experiment, the U.S. government would support the weapons of a U.S. mechanic in Chongqing.

There were people in Harbin in the military and the central commands, so they all sent people to Harbin.

Lead the agents of the Harbin station of the military command to snatch the data of the Meitner nuclear fission experiment.

Now that he heard that Zhou Lin was sent to Harbin by Yamada, Dai Li immediately ordered Yang Kun to accompany Zhou Lin to Harbin, with the help of Zhou Lin's luck.

Therefore, Yang Kun will fly directly to Harbin tomorrow.
