Ning Zhiheng handed over the materials and original film to Huo Yueze, asking him to arrange Deng Yuanhong and his guards immediately to escort back to Chongqing.

Then he personally drafted the telegram and handed it over to Zuo Rou to translate it into a draft, and prepared to send it to Chongqing headquarters at the specified time in the evening.

And at this moment, Chongqing was under an extremely tragic bombing thousands of miles away.

The sound of air defense alarms echoed over the entire city. All offices, residential buildings, streets and alleys were empty. All personnel, with their families, squeezed into the nearest air raid shelter as soon as possible.

Not long after, the Japanese bomber group flew over Chongqing. A dense bomb fell from the air and exploded in the city of Chongqing. The violent explosion sounded deafening, and the black soil was blown up, and shrapnel flew wildly, destroying the surrounding objects.

The bombing-intensive area in the city ignited a fire after a bombing, and for a moment, the smoke filled the air and drifted toward the sky.

Many citizens who had no time to enter the air-raid shelter were submerged in artillery fire. Thrilling screams sounded everywhere, and frightened crowds ran around, crying everywhere for a moment, moaning tragic roars.

The buildings in the bombing area were not spared. The tall buildings, residences, shops, cinemas, department stores, etc. were all swaying by artillery fire, as if they would collapse in the next second, and the scene was terrible.

This kind of scene has happened many times in Chongqing in more than half a year.

Since the Japanese occupied Wuhan, they immediately dispatched a large number of aircraft to Chongqing to bomb with Wuhan Airport as a base. There will be a bombing almost every once in a while, depending on the scale.

The largest bombing lasted for three days. Not only did the entire Chongqing area suffer heavy casualties, but a large number of livelihood buildings were also destroyed, causing the newly emerging metropolis to suffer major trauma.

The bombing time lasted for an hour. The Japanese bomber group threw away all the bombs they carried and then began to return.

When the explosion stopped, citizens walked out of the air raid shelter and bunker one after another, began to rescue the injured and deal with the broken scene.

Two hours later, in the office of the Military Intelligence Bureau headquarters, the bureau's face turned pale and kept walking around the room anxiously.

At this time, the knock on the door sounded.

"Come in!"

The door opened, and Bian Ze, director of the Intelligence Department 1, and Gu Zhengqi, director of the Intelligence Department 2, walked in quickly.

When the director saw the two of them coming in, he immediately asked anxiously: "How is the situation?"

Bianze quickly replied: "Mr., we found Yi Dong's body in the ruins and confirmed that it was dead!"

As soon as these words were said, the face of the director suddenly became even more ugly. This was really bad news.

During this large bombing, many buildings were blown up, and a residential compound in the east of the city was almost blown up to flat ground.

However, this compound is different from ordinary residents. It lives here with three crypto experts and their families from the Telecommunications Office of the Military Affairs Bureau, the crypto deciphering team.

Among them, Yi Dong, the leader of the deciphering team, is the most important figure in the entire deciphering team. He is the earliest expert in contact with code deciphering in China, and is also the leader of the deciphering expert team of the Military Intelligence Bureau.

Not only is he keen on numbers and passwords that ordinary people cannot reach, but what is even more rare is that he once studied in Japan and was proficient in Japanese, and had a great advantage in deciphering Japanese telegrams.

Over the past year, the work of the deciphering team has made great progress under his leadership. Through the captured Japanese codebooks, the deciphering team has conducted countless comparisons and analysis, slowly figured out some rules for Japanese spies' codes, and has successfully deciphered. Recently, the content of Japanese spies sent telegrams in Chongqing has been captured several times, and three Japanese spies have been captured. Among them, Yi Dong, as the main deciphering expert, made great contributions.

The bureau chief has always attached great importance to the Telecommunications Department. A few years ago, during the Military Intelligence Investigation Department, he invested huge manpower and funds to update telecommunications equipment and form a deciphering team. Now he has finally gained something, which makes the bureau chief very pleased.

But he never expected that this Japanese bombing would kill Yi Dong, the technical leader, to death, which brought irreparable losses to the entire deciphering work.

The bureau chief couldn't help but waved his hand angrily and said, "What the hell is going on? Why didn't Yi Dong enter the air-raid shelter in time? Didn't he specially set up an air-raid shelter near their residence?"

The Military Intelligence Bureau has provided good protection for these experts. Chongqing is now overcrowded, and refugees from all over the country have flocked to this mountain city in a short period of time.

Chongqing's urban area has expanded several times in a short period of time, and various construction facilities are constantly being built, but housing conditions are still difficult to improve. Many people even have no tiles to cover their bodies and have to build a straw shed in the open space, forming one slum after another. It can be said that every inch of land in Chongqing is valuable, and now even if they have money, it is difficult to buy a house.

But even under such extremely difficult conditions, the Military Intelligence Bureau tried its best to equip these telecommunications experts with independent houses to facilitate the resettlement of them and their families, and specially arranged air raid shelters near the residences to ensure their safety when attacked. Many senior officials in the government are not as generous as those of such generous treatment.

Hearing the question from the bureau chief, Gu Zhengqi replied in a low voice: "We just asked his family. Yi Dong is unwilling to enter the air raid shelter every time he attacks. His family has no choice but to let him go. The previous air raids were lucky and did not blow up this house, but this time..."

Hearing Gu Zhengqi's report, even the cleverest director couldn't help but curse: "Is he crazy? Isn't he afraid of death! Go to the front line? Why are these people's brains different from others?"

Bianze, who was standing aside, explained: "We asked his family. His wife said that Yi Dong has been from a wealthy family since he was young, and has been kidnapped and locked up in a small dark room for three days and three nights. Since then, he has been particularly afraid of the small and dark places. This is the environment in the air-raid shelter. Therefore, no matter how his family persuades him, he is unwilling to enter the air-raid shelter. He hides in the house to resist. This time he finally did not hide!"

It turned out that there was this reason. The director said angrily: "Why didn't you report this situation earlier? Yi Dong is the leader of the entire deciphering team. I don't need to say the importance, but now everyone is dead. You also know that the entire deciphering work will pause. The battle in Changsha is about to begin. I just handed over the task of deciphering the Japanese military code to them, but now...ah!"

The passwords of Japanese radio stations are generally divided into two types. One is a military password. This password is only suitable for combat use and is replaced very frequently. This military password has a very high level of security and confidentiality. It has its own unique encryption formula, which is extremely difficult to decipher. At present, the Military Affairs Bureau has not yet deciphered a Japanese military telegram.

Another type of telegram password is a password used by diplomatic departments or intelligence departments. This password is used in the largest range and most frequently, and its security level is one level lower than that of military passwords. Several telegrams cracked by the Military Affairs Bureau currently belong to this type of password.

The success of deciphering the code in the previous few times made the bureau full of confidence. He couldn't wait to ask the deciphering team to start deciphering the Japanese military code, but as soon as he gave the task to Yi Dong, he died of a disaster before he could take action.

But this task is Yi Dong. Only his genius brain can complete this extremely difficult task. Other experts assist Yi Dong's work and have no ability to stand alone. It can be said that once Yi Dong dies, the entire deciphering team will have no backbone, and it will be difficult to perform efficient work like before.

Bianze took a step forward and said again: "Standard, we discovered some abnormal situations and felt that Yi Dong's death was not that simple?"

When the director heard this, he opened his eyes and stared at Bianze tightly and asked, "What, are you talking about Yi Dong's death? Is there something else?"

Bianze turned to look at Gu Zhengqi, and Gu Zhengqi quickly said, "Yu Cheng found something at the scene, and he felt something was wrong."

"Yu Cheng? Where is he now?"

“Just outside.”

"Let him in!"

Soon, Yu Cheng, the intelligence chief of the Intelligence Department 2, walked in quickly, holding a ball of red cloth in his hand.

"Master!" Yu Cheng stood attentively and said loudly.

The director pointed at the red cloth in his hand and asked in a deep voice: "What is in his hand?"

Yu Cheng handed the red cloth in his hand to the bureau. After the bureau unfolded it, he found that it was a bright red, long strip of cloth.

The director was an experienced old spy with extremely rich experience. His eyes were sharp. He just glanced at him and quickly reacted and shouted anxiously: "Is this what is used to mark specific targets during bombing?"

Yu Cheng nodded and said, "The bureau clarified the clerk, we also think so. We collected six pieces of broken red cloth strips near the ruins of this compound. We judged that someone should have taken advantage of the fact that when the air defense alarm sounded, everyone hid in the air raid shelter and laid red marking belts in the compound or nearby to guide the target of the Japanese bomber group. In fact, this residence was indeed bombed by Japanese bombers. The compound and several buildings next to it were all razed to the ground, and the bombing density was far higher than that of other bombing areas. This is very abnormal."

"It's indeed not a coincidence!" The director put the red cloth strip in his hand      ＞＞
