"What?"

"In fact, my informant also told me that this sketch of atomic energy* that you drew that needs to be combined into one to detonate is just a device called marksmanship, and in this case it does require 50 kilograms of uranium. But if less material 235 is used to make a round, then around the spherical uranium core, evenly fit the *...... connected by telecommunications tubes As long as all the tubes are detonated precisely at the same time, this explosive force can be used to compress the radius of the sphere towards the core, thus reducing the critical value by several times. ”

Kagesa took a breath and said everything he knew. After Makino was transferred to the "Military Attache's Office in Shanghai" in Shanghai, in addition to continuing to recall the location of the Daqing oil field, in his spare time, he also recorded the principles and history of the * * he knew, including some more general reasons and posterity analysis of why Japan and Germany failed to develop nuclear weapons that he knew, and the name Heisenberg was also among them. Kagesa watched it several times with great interest, at first he thought he was fascinated by the world concocted by a well-thought-out madman, but then he realized that he now seemed to understand part of it. He felt that either such a thing did exist, or that he and Makino had gone crazy together.

As the former elite of the saber group of the Army University, the spy leader's learning ability is very amazing, and he can quickly understand the principles as if he understands what he doesn't understand, so that today he can express these contents very clearly and coherently here, and the real insiders are stunned.

In fact, he didn't exactly know what he was talking about, but at a certain moment just now, when Asaga was prevaricating the results of the calculation of the critical mass of the German scientists, he suddenly felt that Makino could not be a liar anyway—he must have really known that his predecessors had made mistakes; Just as today's schoolchildren know that the earth revolves around the sun, not the other way around, but in the Middle Ages, even first-class scholars had a hard time accepting the intuitive results seen by the eye.

"Where did you get the information? Where are the Americans? ”

Nishina asked eagerly.

"Not only that, but I also know that there is a substance called plutonium-239, which has a critical mass of only 16 kilograms. But this substance does not exist in nature, and it is necessary to obtain a neutron formation by uranium-238 in a device called a reactor. ”

Chaoyong smoked his pipe, frowned, and walked back and forth in the reception room.

Today's visitor really surprised him, the word reactor (atomic furnace) has not been officially included in the Japanese vocabulary, in fact, there are several similar words circulating in small circles within the scientific community, most of which are directly borrowed from foreign language pronunciation, and this rather figurative word used by Kagezo is indeed not a word that a layman can invent. His whole statement, although there are many irregularities, is definitely not like the rhetoric of charlatans, and it is very much like paraphrasing the written knowledge that he is not familiar with, but can roughly grasp the content. In particular, his description of plutonium-239 really scared Asahina, in fact, Heisenberg's critical size estimate of plutonium-239 was roughly the size of a pineapple. From this, he judged, the correct way to build nuclear weapons would be to build a reactor that uses heavy water or graphite as a moderator, rather than blindly enriching uranium. Heisenberg also said at the time that he had only revealed his estimate of the critical number of plutonium to four people at most, and that Asahaga was the fifth.

Seeing that the two scientists were relatively speechless, Kagesa quietly pulled out a photo from the end of his notebook and put it on the table, the one he had seen, the one his hometown of Hiroshima had been razed to the ground. Before he came, he wasn't going to show the photos, he was only going to find out the truth, and he wasn't going to make people feel like he was on the same side as Makino's gang and make himself look like a madman, but now he changed his mind. He was ready to strike while the iron was hot and continue to discuss the issue of time travel.

"The Germans' millions of dollars were not enough to get them close to making such a thing, and my informant told me that Roosevelt had started a secret program called Manhattan, with a hundred thousand men and two billion dollars in investment. So they laughed until the post-war. ”

"Post-war?"

At this point, the swaggering scientist is left to ask questions.

"Yes, the photo shows Hiroshima after it was hit, and as for the time when the Americans used this, if the informant is right, it is today, four years later."

The two physicists stood stiff and mechanically walked to the side, looking at the photograph that had faded slightly after being immersed in seawater.

"The guy in a wheelchair who is dying, it's said to be me." The head of the secret service shrugged his shoulders, "They told me that this is a photo taken a year after the nuclear explosion, and the sores after the explosion equivalent to tens of thousands of tons* have still not recovered." I remember that these scenes must have been Hiroshima, and the forest that should have been on the mountain behind it must have been destroyed by some violent force, and only half of the water tower of the village office was left. ”

"So, someone has returned from the future to the present?"

"Yes, my informant also told me that only the two of you can explain the phenomenon of time travel in Japan today."

"Your informant is from the future to the heart?"

Asahi almost shouted.

Sure enough, the scientist's reaction satisfied Kagesa, and although his tone was obviously skeptical, at least he omitted a lot of stupid nonsense and got to the point.

"No, no, Einstein completely denied this possibility, and in his correspondence with his friends, he made it clear that traveling through time was impossible."

Asahi continued to struggle with a tone of doubt that was 120,000 points of doubt, but it was clear that he was approaching the absurd story.

"Where's your informant? I want to meet him, no, I have to meet him, I have a few questions for him. ”

"There will be an opportunity, and in about a week, I will arrange for all the people who have all kinds of questions to meet with them; Anyone who thinks it's a hoax can use their expertise to debunk it, including the military, politicians, and credible civilians. I want to argue that they are liars in the strictest possible way, or to rule out this possibility altogether. ”

Yoshio Nishina didn't say much at that time, he just grabbed the photo and looked up from time to time to observe, not so much that the discourse on * that transcended the times brought by Kagesa made him really shaken from the inside, but that the old man in the photo was indeed very much like the lively guy in front of him.

"What do they say about this theory?" Chaoyong over there continued to ask questions.

"They found a shipwreck at the bottom of the sea, and the lead on the ship changed in the opposite of the half-life, so that they thought of the whirlpool of time and space reversal nearby, and they traveled to this era in an indescribable way, which was the farthest time they could reach, and according to them, would be able to save Japan in the future and slide into a great defeat."

"How did you find them?"

"Last month, a few of them were dying at sea and were fished up by the navy."

"Why don't you come to us right away?"

"This ......"

"I can't wait another week, I have to see them right away, I have a lot to ask them. Teacher, do you think the same way? ”

Asahaga turns to Yoshio Nishina.

"What does the history of physics tell us?" Nishina suddenly spoke in a calm voice, "That's a new theory, it's always hard to accept, but scientists should be more open-minded than ordinary people, and of course they should be more cautious." I also want to meet with those guys, either to debunk them or ...... Be persuaded by them. ”

Apparently the first stop was a success, and there was no rough treatment.

"Okay, we'll make up our minds, but in any case, please keep it a secret, this matter is about the fate of the empire."

"Don't worry about that."

419 had nothing to do this morning, and continued to circle the sea. Shu Ping's large overload detection was forced to give way, anyway, Lin Xiuxuan couldn't see any need for this kind of detection, and the reactor looked fine.

Due to the limited height, 419 was unable to monitor all communications completely, but the radio still searched for a valuable communication on a new channel, using Soviet-style encryption, which seemed to come from a Soviet station in Shanghai, which had been very careful before, and had never intercepted the communication, Qin Xiaosu recorded the contents, and then easily deciphered the contents.

The telegram indicated that the Japanese intelligence agency in China was presumed to be the Soviet Union and Britain as the countries behind the successive attacks in Shanghai, and that the situation could get worse. In addition, the cable mentions that the operation of the Japanese intelligence chief K in Shanghai is still being traced.

Lin Xiuxuan's first feeling after seeing this telegram was that kidnapping the consulate personnel was like the method of No. 76, and the Japanese usually let Wang's puppet spies do some dirty work. In addition, the Cyrillic letter K is pronounced in the same way as the Japanese pronunciation of the first character of Kagesa's name.

In any case, now is not the time to go back to Shanghai or other coastal areas, the things he did in Shanghai are indeed earth-shattering, and it will take a few days to calm down a little, and he estimates that it will take another ten days and half a month to do it. He felt that during this time, he could approach Japan for a reconnaissance, and stopping in the East China Sea was too passive, and it was easy to miss many opportunities. He developed a new, proactive plan, 419 sailed around Japan, surfaced at night, during the day 419 dived stage, by the drone stranded in the air, intercept and record the air communication to and fro, although the communication could not be monitored in time, but condescending, it was not easy to miss anything. If necessary, the drone can also conduct optical reconnaissance.

He was very worried about whether Kagesa, an old devil, would play a trick with him and not die honestly, what would happen if Kagesa and those three guys went to Japan alive? The more he thought about this possibility, the more frightened he became, and he couldn't sleep at night. He really wanted to immediately convene a meeting of the three to discuss the next step, but Cheng Dayang was still sleeping at this moment, and it didn't seem appropriate to wake him up.
