Don't underestimate this telegram record; the information it contains is extremely important. Ning Zhiheng can find many secrets he needs to know from it.

Ning Zhiheng also took a blank sheet of paper and reviewed the telegrams one by one, translating the telegrams he considered valuable into Chinese and recording them down.

After a long time, Ning Zhiheng finally finished his work, looked up at Yasuda Seiji, and asked, "Where is your codebook?"

Seiji Yasuda gave a wry smile and answered honestly, "It happened so suddenly. When the fire started, everyone was running for their lives. I didn't bring any of them with me. They must have all been burned to ashes!"

Ning Zhiheng nodded. It was a pity that something so important was destroyed. But that was indeed the case at the time. It's impossible to do things perfectly and to take everything into account.

"Did you see Kazuma Tanikawa when you escaped?" Ning Zhiheng continued to ask. Kazuma Tanikawa was of great value. If he was among the few who escaped, then it would be necessary to put in a lot of effort to search for him. After all, capturing a Japanese colonel-level officer was a rare achievement in the entire National Revolutionary Army.

Seiji Yasuda glanced at Ning Zhiheng, his commander's name. He hadn't mentioned it before, but Ning had blurted it out, which showed that Ning knew the Tanikawa Battalion quite well.

"Colonel Tanikawa did not escape. When we rushed out, he was still in the same place. Later, he was not among the people who swam to the other side. He must be trapped in the sea of ​​fire."

The bodies left in the fire were burned beyond recognition, so Ning Zhiheng didn't waste any effort searching. Of the group of over 140 people, only a few escaped. It's normal that Tanikawa Kazuma was trapped in the fire, as his luck wasn't that incredible.

Ning Zhiheng stopped dwelling on this point. He pointed to a message in the telegram record and asked, "Explain this to me: After you entered Pudong, on August 27th, you attacked a temporary aid station in the rear of our army in the Lujiazui area, causing great losses. That same night, you received a secret telegram from headquarters informing you that the Chinese military was going to assemble a large force to encircle and annihilate the rear of Lujiazui. This situation even occurred three times in the following two months. Several telegrams show that before each large-scale encirclement and annihilation operation by our army, you received an alert from headquarters, is that right?"

"That's right. Our operations have become more and more frequent. Kobayashi's squad has successfully attacked the Chinese army's supply lines one after another. That same night, we received a secret telegram from headquarters informing us that the Chinese army would be conducting a sweep in this area. We immediately notified Kobayashi's squad, which allowed them to escape this large-scale search."

There was another similar situation later, and we were able to quickly relocate thanks to an alert from headquarters, thus escaping the search.

However, we did not receive any alarm telegrams from headquarters during this period, and Colonel Tanikawa believed that the Chinese army no longer had the energy to carry out large-scale encirclement and suppression.

But just twelve days ago, Kobayashi's unit, which was supposed to send a telegram to contact them on time, lost contact and hasn't been heard from since. It's presumed something has happened to them.

At this point, Yasuda Seiji looked up at Ning Zhiheng. This matter had to be made clear: the disappearance of Kobayashi's squad must have been the work of the Chinese army, and they must have known about it, so there could be no concealment.

As expected, Ning Zhiheng nodded in satisfaction and said to him, "Yasuda-kun, your attitude is very good. The explanation of the situation must be detailed. This situation was not marked in your telegram record, but I am very satisfied that you took the initiative to bring it up."

Seiji Yasuda quickly nodded and said, "It was all my oversight. Please forgive me, sir. This kind of mistake will not happen again. It will definitely not happen again!"

These three telegrams alone are enough to show that someone within the Chinese army was tipping off the Japanese. This is not surprising, as the Japanese intelligence organization has been preparing for decades. Even highly confidential intelligence departments like the Military Intelligence Investigation Bureau have been infiltrated by high-ranking spies like Yan Yichun. The situation would be even more serious in ordinary combat units.

However, the scope of such an investigation is too broad. With the encirclement and suppression by a large force, there are simply too many people in the know, from the command headquarters to the execution troops. It is too difficult to investigate them all!
