Double-Cut During the War of Resistance: My Wife Came from 1937

Ma Hongwei contacted several manufacturers to inquire.

[Ma Hongwei: "Are you there? Has the batch of goods I ordered been produced?"] ×4

With many manufacturers available, he simply chose to copy and paste.

A reply came very quickly.

[Manufacturer 1: "The cotton hats have been produced, and we can ship them to the boss anytime he needs them!"]

[Ma Hongwei: "Then send it. I'll give you the address!"]

[Manufacturer 2: "The thermal underwear has already been produced. Boss, do you want it now?"]

[Ma Hongwei: "Yes, I need it now. I'll send you the address later!"]

Manufacturer 3: "Sorry, boss, you need one with a wool lining. It's more complicated to produce, you can't let the wool shed, and quality control is more time-consuming."

[Ma Hongwei: "Your production is too slow!"]

[Manufacturer 3: "The day after tomorrow, it will definitely be delivered by the day after tomorrow!"]

Ma Hongwei: "Okay, then the day after tomorrow."

[Manufacturer 4: "Boss Ma, leather shoes have many processes involved and are very troublesome to produce. There are still some missing, but we can definitely ship them out by tomorrow night!"]

Ma Hongwei: "..."

[Ma Hongwei: "If it's not delivered by the morning after tomorrow, then I don't want it."]

Manufacturer 4: "If it's the day after tomorrow, I guarantee it will be delivered."

Ma Hongwei: "Okay, okay."

After contacting those manufacturers, Ma Hongwei then contacted his previous wholesaler, Boss Xue.

[Ma Hongwei: "Boss Xue, do you have any fleece-lined cotton gloves and socks?"]

[Ma Hongwei: "And fingerless gloves, these also need to be kept warm."]

[Boss Xue: "Yes, but I don't know how much the boss needs?"]

[Ma Hongwei: "I need 20 pairs of cotton socks, 5 pairs of cotton gloves, and 5 pairs of warm fingerless gloves."]

[Boss Xue: "This... I'm really sorry, Boss Ma, you've ordered too much. I can't possibly have that much stock on hand all by myself."]

[Ma Hongwei: "So how much can you provide now?"]

[Boss Xue: "We can only provide 35000 pairs of thick cotton socks, 18000 pairs of cotton gloves, and 13000 pairs of fingerless gloves."]

[Ma Hongwei: "Okay, Boss Xue, could you contact the others for me again? This time, you need to get me 50000 pairs of cotton socks, and 40000 pairs of cotton gloves and half-finger gloves. You can arrange the rest of the goods; I'll ask you for them next time."]

[Boss Xue: "Since Boss Ma has put it that way, I will definitely do it for you."]

[Ma Hongwei: "What are the prices?"]

[Boss Xue: "We have regular thickened workwear, as well as a high-end version specifically designed for cold regions, which offers better quality and warmth."]

Ma Hongwei: "Of course, it has to be of good quality."

[Boss Xue: "Mid-calf terry cloth socks are 1 yuan a pair, and high-calf thick terry cloth socks are 1.3 yuan."]

[Boss Xue: "Thickened and fleece-lined cotton gloves with a brushed fleece lining are 2.8 yuan a pair, while double-layered fleece-lined gloves are 3.5 yuan a pair."]

[Boss Xue: "Warm fingerless gloves, knitted and fleece-lined, 2.2 yuan a pair; extra-thick fleece-lined, 2.7 yuan a pair."]

[Ma Hongwei: "It's not a big deal, let's go for the best!"]

【薛老闆：「这样的话50000万双高筒加厚毛圈棉袜就是65000元；40000双双层加绒棉手套140000元；40000双的加绒保暖半指手套108000元！」】

[Boss Xue: "Without shipping, the total is 313000 yuan."]

Compared to the previous cotton-padded coats, leather boots, and cotton military caps, these were just small change.

But it also allowed him to earn a small sum of money.

Ma Hongwei: "The deposit is still 20%, right? I'll transfer it to you in a bit."

[Boss Xue: "Thank you, Boss Ma!"]

……

After finishing these tasks, Ma Hongwei said to Xia Weiwei, "We've bought all the warm clothes. Is there anything else we need to buy?"

"It seems there aren't any left."

Xia Weiwei shook her head, then added, "By the way, Hongwei, the Central Committee sent us a mission to find a way to crack the Japanese army's radio codes. Do you have any ideas?"

"Cracking the Japanese military radio code?"

Upon hearing this, Ma Hongwei frowned.

He knew absolutely nothing about radio.

However, in later generations, we have the Internet, so we can look up anything we want to know.

"Let me search and see if there are any books on this topic."

As Ma Hongwei spoke, he immediately started searching on his phone.

"what?"

Ma Hongwei searched online and found that there were quite a few books like this.

"There really is!"

Ma Hongwei said, "There are quite a few books. This one, 'The Code Wars,' published by Huaxia Literature and History Press, is a memoir by a core participant in the Nationalist government's code-breaking efforts against Japan. It details the operation of the code-breaking office and the code-breaking process of the Japanese Ministry of Foreign Affairs and the Army."

"There is also this book, 'The Military Intelligence Bureau's Code War Against Japan,' or 'The Black Chamber of China,' which is a firsthand record of the experiences of Yardley, the 'father of codes' of the United States, when he served as an advisor to the Military Intelligence Bureau from 1938 to 1940. The original manuscript was once banned by the United States for 40 years."

"Other books include 'The Secret War Between China and Japan,' 'The Battlefield That Cannot Be Ignored,' and 'Chronicle of a Decryption Career.'"

"However, these books lack a large amount of original ciphertext and precise technical details, and can only be used as a reference, not for direct decryption."

"In addition to these books, you can also search for some archives, such as the Kuomintang archives related to the Military Intelligence Bureau, the declassified Japanese military code details from the US archives, and the Japanese military documents released by the Japanese Ministry of Defense itself."

Xia Weiwei said, "Even so, it will reduce the difficulty of deciphering. As long as we can successfully decipher it, the Eighth Route Army can easily grasp the movements of the Japanese army."

"It's a pity that there's no internet in that world. Otherwise, if we bought a good computer and used AI to help decipher it, we might be able to decipher it directly."

Ma Hongwei shook his head and sighed: "Although AI can be deployed locally, relying solely on the content of those books and locally deployed general-purpose AI models is insufficient to completely decipher the codes used by the main force of the Japanese army."

"Unless we can seize a large amount of encrypted data for statistical and pattern matching purposes, because AI also needs a lot of data to analyze, and cannot generate it out of thin air or rely solely on algorithms to calculate it."

Ma Hongwei did another search and found that he could directly buy cipher machines or decryption machines from World War II.

An antique original German Enigma machine, which is still in use, costs between $25 and $40.

For a commercially available 1:1 replica, it costs only 3000 yuan on domestic e-commerce platforms, while products from overseas professional brands cost 900-1400 US dollars.

As for the cipher machine used by Xiao Rizi, it is only found in military museums in China and Japan.
