The Eighth Route Army needed supplies, and after the Japanese army launched the Pacific War, it was also in desperate need of supplies.

In order to get rid of the dilemma of material depletion, the Japanese army established the Rice Grain Control Association, the Trade Control Committee, the Leather Control Committee, and the North China Petroleum Control Committee in Haigu.

A strict lockdown was imposed throughout North China, and iron and steel wires, telecommunications equipment, sulfur matches, and medical and sanitary supplies were absolutely forbidden to be shipped out.

Rice and wheat are all controlled and stored by the balanced warehouse, and miscellaneous grains are strictly controlled and distributed by the Haigu Branch of the Granary Procurement and Transportation Society.

In the past, the Japanese puppet conducted a comprehensive investigation of the city's materials, and it will be very difficult to trade all kinds of materials at will.

Lu Chengzhou quickly reported this information to the organization.

Lu Chengzhou feels that starting from this year, the Anti-Japanese War will enter a truly difficult period.

Haigu is the largest city in North China, and before the Japanese army carried out an economic blockade, many of the supplies in short supply of the Eighth Route Army could be purchased from Haigu.

Now, even if there is a relationship with Lu Chengzhou, it is difficult to buy in large quantities.

On New Year's Day in 1942, Lu Chengzhou and Ma Yuzhen had dinner together in a Parisian restaurant in the French Concession.

They eat out to talk about work and to lurk.

"Today, Huang Jizhen came to the police station and served in the special high section." After Lu Chengzhou finished waiting for the dishes to be served, he placed a napkin on the side and said softly.

"Huang Jizhen? It turns out that the one in Tangshan? Ma Yuzhen exclaimed in a low voice, the reason why Zhang Xuanping was arrested in the past was precisely because of Huang Jizhen's rebellion.

Zhang Xuanping was sent back to the base area, and although he ostensibly cooperated with the gendarmerie, in reality, he was still a party comrade.

But Huang Jizhen is different, this is a real traitor.

"It's him, you have to tell Mr. Gu, you must pay attention in the future. At the same time, it should be specifically explained to the family that Huang's arrival may endanger Mr. Gu's safety. Lu Chengzhou said slowly.

Huang Jizhen used to be a high-ranking official in Tangshan City, although he didn't have much contact with Gu Sanshi, the two must have known each other.

After all, they both belong to the Pinghai Tang Point Line Working Committee, and both of them are also members of the Pinghai Tang Point Line Working Committee.

"Okay." Ma Yuzhen nodded, this information has to be sent out tonight.

"There is another thing, I heard that the Third Army is preparing to sweep Yanshan Pass." Lu Chengzhou suddenly lowered his voice and said.

"They dare to come out and sweep?" Ma Yuzhen felt a little funny.

After the Third Army arrived in eastern Hebei, it had always been cowering in its garrison and had almost never been dispatched.

At most, that is, in the surrounding areas, limited operations are carried out.

"This is meat delivered to the door, if you don't eat it, you'll be sorry for yourself." Lu Chengzhou forked a piece of beef, gently put it in his mouth, and said slowly.

He is now the police chief of the Extreme District and often attends meetings of the Municipal Police Department, the Extreme District Office, and even the Municipal Office.

"I know, you must have another ghost idea." Ma Yuzhen saw a mysterious smile on Lu Chengzhou's face, and knew that he must have a plan.

"Looks like you still know me." Lu Chengzhou put down the knife and fork and said with a smile.

This time, the Third Army swept Yanshan Pass, no matter which regiment or two regiments were sent to act together, he would create some trouble for the Third Army.

"Hurry up." Ma Yuzhen looked around, and after finding no abnormality, she asked anxiously.

"Road 26 in the polar tube area should also be used." Lu Chengzhou chuckled.

"Hurry up, or I'll be angry." Ma Yuzhen said coquettishly.

"Didn't you report last time, could there still be an 'underground party' in the Third Army? This time, the 'underground party' is about to surface. Lu Chengzhou whispered.

Last time he investigated the so-called underground party in Qian'an County, although he killed four people, those people were just a few scum.

At that time, Lu Chengzhou had already left his tail and reminded Kawasaki Hiroshi that there might be an underground party in the Third Army, and this underground party was very likely to be hidden in the upper echelons.

This time, as long as the Third Army is dispatched, no matter who leads the team, the person who leads the team must be the underground party.

"You're too bad, aren't you?" Ma Yuzhen said.

"Being merciful to the enemy is tantamount to suicide." Lu Chengzhou said coldly.

When she was about to finish eating, Ma Yuzhen took out a pen and wrote a piece of information.

Unlike Lu Chengzhou, she has to use her left hand to change her handwriting.

Ma Yuzhen writes directly with her right hand, and she can write several kinds of handwriting.

After eating, Lu Chengzhou used the car to send Ma Yuzhen to the vicinity of the dead mailbox, and Ma Yuzhen only took two minutes to put the information in.

Gu Sanshi only received the information the next day, and Huang Jizhen's arrival really made him a little nervous.

But when he saw that the Third Army was going to Yanshan Pass to sweep in the near future, he became anxious.

His personal safety is nothing, and isn't participating in the revolution a sacrifice? This point has been clearly expressed when he first read the oath of joining the party.

Gu Sanshi wanted to send the information home immediately, but thinking about Li Xiangxue's previous advice, he quickly calmed down again.

The military movements of the Third Army will certainly use radio contact.

And the communication codebook of the Third Army has long been obtained by ants and delivered to the home.

And the ant also proposed a plan to kill people with a knife, and this plan requires the cooperation of the family.

Three days later, Xie Xiangchun arrived in Haigu and got in touch with Gu Sanshi.

Since the Japanese army forcibly occupied the British and French concessions, Gu Sanshi originally thought that it would be more difficult for Xie Xiangchun to come to the concession.

However, the ants gave him a few of the latest passes, which made it more convenient for Xie Xiangchun.

Gu Sanshi is sometimes also curious about the identity of ants, after the Japanese army occupied the LinkedIn concession, how did he get a pass so quickly?

Moreover, the level of these passes is quite high, even if it is inspected by Japanese soldiers, as long as you take a look, you will be released.

"Lao Xie, you can't rest today, you have to go back quickly." After Gu Sanshi saw Xie Xiangchun, he handed an envelope to the other party.

"My ass is still hot, so you can drive me away." Xie Xiangchun took the envelope, stuffed it into his socks, and said with a chuckle.

"The situation is urgent, this is the information from three days ago, can you rush home tonight?" Gu Sanshi asked.

"Yes." Xie Xiangchun said suddenly.

He can joke with Gu Sanshi, but he must not be sloppy at work.

"Good work." Gu Sanshi patted Xie Xiangchun on the shoulder.

"What's polite with me?" Xie Xiangchun took a sip of tea and turned to leave.

He was a political communicator sent by the organization, and he had to go back as soon as he handed over the information.

On January 12, 1941, the Fourth Regiment of the Third Group Army swept Yanshan Pass, and the 13th Regiment of Bao Sanmu, who had learned the news in advance, marched rapidly overnight and set up an ambush in a radius of more than ten miles along the north bank of the Guohe River, Yangezhuang and Cailaozhuang.

This time, Bao Miki was very determined to eliminate this fourth regiment in one fell swoop.
