Jiang Zhongbin also learned how to make bombs in the Military Commission's spy training class. He knew that this formula was the formula of black gunpowder. Jiang Zhongbin learned how to make black gunpowder and how to make bombs. Of course, he would also make such bombs, but he did not participate in the production of earth bombs because if he wanted to hide his identity, he had to pretend that he knew nothing about explosives and bombs.

A few days later, the guy really made two earth bombs. On a clear Sunday, these greedy young people found a large pond. Beside the pond, they ignited a earth bomb and threw it into the water.

"Boom", the power of the earth bomb is really great. After a muffled sound, a white layer floated on the water surface. The big and small fish in the water were stunned by the explosion's shock wave and all floated onto the water surface.

"There are fishes and fishes and they are fishes and they are eating them." The young man cheered. Whether the soil bomb can be fired is an unknown. These people originally came to play with a try-through attitude, but they didn't expect it to be successful the first time.

The temperature in July was very high, and these young people took off their clothes and jumped into the water. The water was full of big and small fish, and these people wanted to grow a third hand to catch all of these fish ashore.

After a while of busy work, the young man caught a lot of fish. An anxious guy immediately dug a pit on the ground and got firewood. After cutting the fish's stomach and buckled the gills and washed them, the young man surrounded the fire pit and put the fresh fish on the branches and grilled the fish with fire.

There was no oil or salt, and the grilled fish was tasteless, but young people who hadn't seen meat for a long time didn't care about these, so they picked it up and chewed it. As for the taste of this grilled fish, according to Jiang Zhongbin's remark, "That fish, maybe the most delicious thing I've ever eaten in this life."

Just as they grilled the fish and were having a feast, a team of soldiers in gray cloth uniforms surrounded them, and finally confiscated their fish and brought them back to Yan'an.

The one who took them away was not someone else, but the security team of the Shaanxi-Gansu-Ningxia Border Region Security Department. The border security team came so quickly, which was thanks to the timely reports from the people in the border region.

In Yan'an, the security department of the Shaanxi-Gansu-Ningxia Border Region is the security department of the Shaanxi-Gansu-Ningxia Border Region, referred to as Border Protection. The security department actually has two signs, the Social Department of the Northwest Bureau internally and the Border Protection Department externally. The security department is composed of the security department agency of the Border Protection Department, the Border Protection Security Group, the Yan'an Municipal Public Security Bureau, etc. The security department is responsible for the security work of the entire Yan'an, among which the agency is mainly responsible for investigation, intelligence, interrogation and other work, while the security team and the Yan'an Municipal Public Security Bureau are responsible for specific execution tasks.

Among them, the frontier of the Border Security Security Corps was the guard team under the Red Army. During the Red Army period, there were only more than 100 central security teams, which was equivalent to a reinforced company. After the Red Army arrived in Yan'an in the Long March, the central government mobilized elite soldiers and generals from each unit to expand, and the troops were organized into one regiment with three battalions under the regiment. At present, the cadres of this unit are all old Red Army soldiers who are loyal to many battles, and 80% of the soldiers are Communists.

The weapons equipped by the Border Security Security Group include machine guns, rifles and a large number of barge guns, but they are not equipped with artillery and belong to the internal security forces in nature. After development, this security force in the Shaanxi-Gansu-Ningxia Border Region became the predecessor of the Chinese People's Armed Police Force.

During the War of Resistance Against Japan, Japan's espionage activities in China were omnipresent. The three major espionage systems of Japan's military headquarters, government and military police all regarded Yan'an, the location of the Central Committee of the Communist Party of China, as the focus of espionage activities. Even as a friendly party, the Kuomintang, the Central Committee of the Central Committee, never gave up the task of anti-communism in one day. Things like sending personnel to infiltrate and infiltrate almost every day.

Under this situation, the work of the Border Security Security Department is extremely important and extremely arduous. In order to cope with this complex situation, the Border Security Department actually has two sets of agencies, namely, light and dark. The ones in the open are the security department, the public security bureau and the security team, as well as special commissioners stationed in various agencies, units and the army. Those hiding in the dark are "working network workers" who work part-time in various agencies and units and live among the people.

Although the place where these students fry fish was in a remote fish pond, the loud noise still alarmed a "working netist" of Bianguan. Seeing someone committing an explosion in Yan'an, the netist immediately reported the case to Bianguan.

Zhou Xing, director of the Border Security Department, had a scalp blown when he received this situation, and his cold sweat suddenly came out.

What is Yan'an? It claims to be the capital of the Shaanxi-Gansu-Ningxia Border Region, and the internally it is the capital of the Communist Party of China. It has a red heart, and is home to Zhu Mao and other party, government and military leaders. These young people can create a bomb to blow fish. What if they do something else with this bomb?

After being shocked, Zhou Xing immediately gave an instruction, that is, he must catch all these people, and he must see who can make such a big noise in Yan'an.

The Border Security Team acted very quickly. Under the leadership of the work network staff, they quickly surrounded these young people and brought them back to Yan'an.

In the yard of Bianbao, some Bianbao cadres laughed at these young students who were bold and arrogant because of their delicious food, while Zhou Xing and others, who had a very rich experience in fighting the enemy formation, saw some clues from it.

Black gunpowder is one of the four great inventions in ancient China, with a history of more than a thousand years. In China, black gunpowder has been widely used in the production of fireworks and firecrackers, and its formula is no longer a secret. Because of its wide source of raw materials, it is not difficult to make it, so it is not new for some people to create a bomb.

But the problem is that the earth bomb that has not been detonated. After Zhou Xing and others dismantled the earth bomb, they found that the method of making this earth bomb was exactly the same as that of the military secret service training class.

Among these students are military commanders, or people with considerable relationships with military command

Zhou Xing immediately ordered the guy who made the bomb to be detained and interrogated, and further review of the other students.

The guy who made the bomb could not withstand the surprise interrogation of Border Guard interrogation experts. He quickly confessed that he was a person sent by the Military Control Commission.

The Military Control Commission and the Communist Party’s security department have experienced many years of secret wars, but there has never been any results that can be achieved. After suffering a series of failures, the Military Control Commission began to change its methods. Now the Military Control Commission usually uses a single-line connection method to Yan'an, and will not contact each other vertically in the most critical situation. Although Jiang Zhongbin and this bomb-making guy were sent in almost the same time, there was no direct connection between the two, so they did not know their respective existences.

This exposed military commander is actually very afraid of death. In order to make meritorious service, he revealed everything he knew almost immediately. Because he really didn't know Jiang Zhongbin's identity, Jiang Zhongbin was not exposed by him.

After Bianbao's review, Jiang Zhongbin was very positive in his daily life and had a good impression of the school teachers and classmates. After the school investigation, Bianbao determined that he was tempted and deceived, so he quickly released him. However, Bianbao notified the school to strictly monitor young students like Jiang Zhongbin, and pay more attention to his ideological trends in daily life to help him improve his ideological awareness, so as not to be deceived and exploited by spies again in future study and work.

After returning to school, Jiang Zhongbin naturally became the target of assistance. The school, district team and various people came to him to talk about his thoughts and enemy situations one after another. Even the classmates living in a cave took action and paid great attention to him in terms of study and life.

If you become the center of attention of others, you will become a person under a magnifying glass. This is a taboo for any lurking person. Jiang Zhongbin is being watched by others at all times now. He dares not say too much or move too much, for fear that he will be caught by others if he accidentally. This careful life makes Jiang Zhongbin feel like he is on pins and needles and needles, and lives like a year.

The loss of a military commander who had successfully entered the Shaanxi Provincial Public School was lost due to the fish blowing. The news was quickly spread back. The military commander had always lagged behind the Central Commission for intelligence work on the CCP, but this time he was almost successful. After learning from his mistakes, they made a decision, which was to regularly issue some allowances to the spies sent to Yan'an to improve their lives. In order not to expose the identities of the hidden personnel, the amount of these allowances was not large, and the military commander liaison officers would secretly deliver them to designated locations in various places, and the military commander hidden in Yan'an would receive them separately.

Because they were all single-line contacts, Jiang Zhongbin saw a secret note asking him to receive items at his contact location. However, because he was being followed at all times, Jiang Zhongbin did not dare to take the risk of taking out the things he sent behind.

A few days later, a news came, saying that Border Protection captured the Kuomintang spy this time, and this spy was the liaison officer who gave the allowance. In fact, this military liaison officer had long been targeted by the Second Department of Border Protection. The liaison officer who gave the allowance was a hurry. His identity was exposed because the Border Protection officer found that the cigarettes he smoked were relatively advanced.

At this time, there were two county governments in Yan'an, one appointed by the Shaanxi-Gansu-Ningxia Border Region Government led by the Communist Party, and the other appointed by the Kuomintang Shanxi Provincial Government. The Kuomintang officials naturally could not live such a hard life, and their daily necessities were specially transported from outside. At this time, the road conditions were poor and the transportation was extremely tight. The Military Control Commission adopted the most primitive method of carrying mules and horses. This liaison officer specially drove mules and horses to transport various daily necessities to these Kuomintang officials...
