However, after sending the first letter, Song Shutian did not receive any further exchange information.

He had also discussed it with Liu Zhanyu, and they concluded that it was most likely related to the improvement in Jiang Qiao's treatment.

If the patient's health actually improves because of Jiang Qiao's medicine, then it would be better to keep Jiang Qiao around, cure the patient directly, and then bring in Sato; that would be much more efficient.

As for the identities of Bai Qingping and Ye Xiuhe, the people behind them got busy after the investigation order was issued, because Jiang Jinyu had already spoken up and wanted to re-examine the enemy agents who had been arrested. There were some things they might not have said, or they might have forgotten to say.

This time, we must be meticulous. The people we're arresting, like Jiang Qiao, can't exist independently; they must have some connection to those enemy agents.

Re-interrogation requires manpower and time. Jiang Jinyu received a lot of interrogation materials one after another, then checked them, and sent the relevant information to Song Shutian.

After looking at the information, Song Shutian and Liu Zhanyu both frowned.

"What do you mean? This Bai Qingping might be Uncle San's direct subordinate? Are you kidding me?"

Song Shutian stared at the documents without looking up. "What's so strange about this? The Japanese are getting anxious too. So many people have had problems, how could they not be worried?"

The key issue is that the old Japanese soldier doesn't know the situation yet. If this person dies prematurely, I feel that their objective might be difficult to achieve.

I can't say what they'll do next; they might retaliate fiercely.

"Tsk, what exactly is this Ye Xiuhe's identity? Why are the accounts so conflicting?"

Liu Zhanyu took a look and said, "The director probably didn't get a real assessment either, so he could only give you the information first. I guess they're still investigating right now."

Look, this doesn't say that this person joined later. How could he gain the trust and acceptance of those shrewd Japanese devils? Without some background and status, would these people trust him?

I think Jiang Qiao's previous judgment was correct. This woman should be a descendant of some prince, minister, or royal family member. Isn't it written in the document that this is the most likely possibility?

"Don't forget, the Manchus also had many veteran officials and staunch loyalists at that time. Perhaps this Ye Xiuhe was just a young lady from some family, born to a concubine, and not particularly outstanding, so nobody paid attention to it. What do you think?"

Song Shutian nodded thoughtfully. "You know what, your analysis makes a lot of sense. So tell me, is this woman a good person or a bad person? And what was the meaning behind that line she said to Jiang Qiao?"

Liu Zhanyu sat down and crossed his legs. "It's simple. Get to know Jiang Qiao and then infiltrate our ranks. Even if you can't infiltrate her, at least you'll have that connection. She'll be able to find out where the old devil is being held."

Once Jiang Qiao develops the drug, that person might intend to send it to the old Japanese devil. If the old Japanese devil manages to get the antidote, things will become quite uncertain.

That old guy is very cunning. If he succeeds and leaves that place, what do you think will be the first thing he does?

"They must have contacted that Sato Mie. The two of them are working together on something big. I have a feeling that they have other secrets. It's definitely not as simple as just causing trouble. What could it be? Lao Liu, have you figured it out?"

Liu Zhanyu gave a wry smile. "Me? My brain capacity isn't enough. In that respect, I really can't keep up with Sato and the others. If we follow their crazy thinking, I always feel like they might be trying to become immortals."

"Tch, becoming an immortal, huh? You really dare to dream of that—"

As soon as he finished speaking, he suddenly remembered something. What Sato had done over the years had suddenly given him a bold idea. However, he was also frightened by his own idea. His face darkened, and he remained silent for a long time.

"What are you thinking? Is there any hope or not?"

Song Shutian shook his head, trying to shake the thought out of his mind, but it was no use. Once it popped up, he couldn't shake it off no matter what.

"Old Liu, what do you think Sato is trying to achieve by going through all this trouble? There must be some purpose to it. Searching for legends all over the world, looking for something that can grant immortality, doesn't seem very reliable to me. There must be something behind this that we don't know about."

Liu Zhanyu shrugged. "Who knows? Just like that inexplicable incident I investigated before, to be honest, I couldn't explain it either."

Could it be that Sato also likes these things?

At this point, Liu Zhanyu looked at Song Shutian with a suspicious expression, "Little Song, don't tell me that Sato wants to fly to the sky?"

Liu Zhanyu dared to say this because he was investigating something beforehand: a large area of ​​forest had been inexplicably destroyed, and the traces did not seem to be man-made.

The key point is that the surrounding rocks look like they've been burned. According to one or two eyewitnesses, they saw a bright light flash across the surrounding mountains in the middle of the night, and then a plate-shaped object floated across the sky and disappeared in an instant.

The only thing he could think of was that Sato wasn't after this kind of thing.

Song Shutian gave a wry smile. "We really can't be sure. This guy from the old man's family is cunning and wicked. We've never known what he's thinking. When we interrogate him, he just stays silent."

"Old Liu, keep a close eye on things here and make sure Jiang Qiao is safe. I need to go back for something."

Liu Zhanyu smiled and nodded, "I think it's a good idea. It's a pity that the old Japanese devil has never been of any use."

Also, go back and investigate whether there's a traitor among us. How did Jiang Qiao know about the book and jade token?

Liu Zhanyu had always harbored suspicions about this matter. Since phone calls and telegrams were inconvenient, and Song Shutian was going back, this matter definitely needed to be investigated.

“I know. Logically speaking, besides the few of us, the only other person who submitted the report was the section chief. However, he is a fine person. I also suspect that someone in our group leaked the information. Whether it was intentional or not is hard to say.”

Alright, be careful in everything you do, and let's stay in touch.

Liu Zhanyu patted Song Shutian on the shoulder and said, "I also wish you success. It's time to take down this old devil. Without these devils causing trouble, we can focus our energy on dealing with those enemy agents."

Although Liu Zhanyu didn't know what Song Shutian was going to do when he went back, he felt that for Song Shutian to give up Jiang Qiao and leave at this time, this person was probably thinking of something and preparing to make a big move.

Thinking about it, it makes sense. For the past few years, these Japanese devils have been leading him by the nose. If he doesn't beat them to a pulp this time, he'll feel like he's wasting all his years of effort. As for the little girl, she should be awarded another first-class merit.
