Gu Zhengqi nodded and said, "Director, we believe that this was a targeted assassination of our Military Intelligence Bureau's decryption team by the Japanese military. Judging from the density of their bombing of this residential area, their target is very clear: Yi Dong. However, the success rate of such an assassination is very small. After all, as soon as people discover that planes are bombing, they will usually hide in air-raid shelters immediately, making it difficult for the Japanese bombing to succeed."

Therefore, the Japanese need several necessary conditions to achieve this.

First, we need to find out Yi Dong's exact address. However, there are quite a few people who know where these codebreaking experts live. Most of the houses in this area are occupied by family members of Military Intelligence Bureau personnel. They communicate with each other from time to time, and many people know about these situations, making it difficult for us to find them.

Secondly, the Japanese knew that Yi Dong had a fear of confined spaces and a habit of refusing to enter air-raid shelters during bombings. They knew that Yi Dong was hiding in a house when the bombing was scheduled, which is why they deliberately increased the bombing intensity, destroying all the houses in the area. Anyone who knew about Yi Dong's peculiar condition must have been very familiar with him. This suggests that the problem lies within our ranks; there are Japanese spies among us.

Bian Ze added from the side, "The Japanese have a very clear objective in this bombing: to eliminate Yi Dong. They even used a bomber squadron and deployed personnel to place bombing markers. This shows their determination and willingness to pay any price. We have never encountered a situation like this before, and they have never attached such importance to our decryption team."

Is it possible that the Japanese knew Yi Dong had mastered the skills to decipher Japanese intelligence codes and was now about to begin deciphering Japan's proprietary military codes? This made the Japanese extremely nervous; they feared that Yi Dong's successful deciphering would have an immeasurable impact on the war situation. To prevent this, they went to great lengths to assassinate Yi Dong!

Upon hearing this, the Director could no longer sit still. He knew very well that the person who had given the decryption team the task of decrypting Japanese intelligence codes must be either by his side or by Yi Dong's side.

No, it must be someone close to Yi Dong, because even they themselves didn't know that Yi Dong had autism. This person must know Yi Dong very well to be able to do something like this.

"Investigate! Conduct a thorough investigation! Find everyone who knows Yi Dong has this autism, everyone who knows I gave the order to decipher military codes, and investigate them all. We must find this traitor!" the bureau chief shouted.

"yes!"

"yes!"

Everyone acknowledged the order in unison. Gu Zhengqi hesitated for a moment before continuing, "Director, there's one more thing. According to our reconnaissance, over the past six months, the radio signals from unidentified radio stations in Chongqing have been increasing. This suggests that Japanese spies have emerged and begun to conduct intelligence activities frequently, and their activities are becoming increasingly rampant."

According to reports from our informants in various departments, the recent intelligence leaks in our government and military departments have been very serious. Major leaks have occurred in the Ministry of Foreign Affairs and the Military Commission, but they dare not make it public and are conducting investigations in secret. At present, we cannot forcibly intervene.

Moreover, the confessions of the three Japanese spies we just arrested also show that the Japanese have rebuilt a huge intelligence network in Chongqing and put it into use.

However, we don't have any effective means to deal with this. Now that Yi Dong is dead, deciphering their telegrams has become even more difficult. So, as things stand, it seems that our Second Intelligence Division is indeed somewhat overwhelmed in its work to investigate the Japanese spy group in the Chongqing area!

Unlike the First Intelligence Division, which was specifically responsible for external intelligence, Gu Zhengqi's Second Intelligence Division was responsible for internal intelligence investigations and the capture of Kuomintang spies. Therefore, internal counter-espionage work was mainly handled by them.

Before the full-scale war of resistance against Japan, Gu Zhengqi had spent a lot of effort planting many spies in various departments of the Kuomintang. So he was well aware that a new undercurrent of espionage had begun to emerge within the Kuomintang and was developing in a bad direction. However, his investigation had not yielded any significant results, so he had to ask the Director for help!

The bureau chief looked at Gu Zhengqi and asked suspiciously, "What are you trying to say?"

Gu Zhengqi said in a low voice, "I would like to ask the Director for his approval to deploy Director Ning Zhiheng to carry out a large-scale crackdown on Japanese spies lurking in the Chongqing area. With his counter-espionage capabilities, I believe that he can deal a heavy blow to these Japanese spies in a short period of time!"

Although Gu Zhengqi was shrewd and experienced, he was very respectful of Ning Zhiheng. This youngest action director of the Military Intelligence Bureau had won the respect of all his seniors with his outstanding talent and achievements. Whether it was Gu Zhengqi, Bian Ze, or Zhao Ziliang, they all placed him on an equal footing with themselves and dared not use seniority as an excuse.

While at the Nanjing headquarters, Ning Zhiheng displayed his exceptional skills in just six months, wiping out the Japanese intelligence network that had been cultivated for many years with overwhelming force, completely reversing the offensive and defensive posture of Chinese spies. This left an indelible impression on everyone, and everyone had to admit that Ning Zhiheng was the number one counter-espionage expert in the Military Intelligence Bureau.

The current situation in Chongqing is extremely similar to that of Nanjing, and it could even be said that the situation is worse. Nanjing, the capital at the time, had many years of construction and management, and had extremely convenient conditions for investigation in terms of security forces and household registration management. Therefore, the environment and foundation for the investigation work were very good.
