In order not to arouse suspicion from the Japanese and Li Zhiqun, Luo Xingchao conducted a very detailed investigation at the Special Agent Headquarters. He investigated almost everyone who was suspected, even those close to Li Zhiqun. After summarizing the findings, he reported to Li Zhiqun.

"Director, I have investigated all the personnel who stayed at headquarters on the night of the 29th. However, due to the heavy rain that night, many people did not go home and stayed at headquarters for the night, so there were quite a few people."

The heavy rain had erased all traces, and the patrolmen and guards had stayed indoors all night to avoid the rain. After questioning them for a long time, they found nothing.

After hearing this, Li Zhiqun also had a headache. He was currently preoccupied with many matters and injured, so he really didn't have the energy to investigate this matter personally. He could only leave it to Luo Xingchao to handle. If even Luo Xingchao couldn't find any relevant clues, it was clear that this task was indeed very difficult.

He thought for a moment, then said, "Then let's put the work on the infirmary and see if anyone has been frequently scouting the infirmary recently. To complete the poisoning procedure, a lot of preparation work needs to be done."

Luo Xingchao also agreed, but still spread his hands and said, "I've thought of this problem too, but it's quite difficult to actually investigate. Because of the conflict with Ding Mo during this period, we have too many wounded. The medical room is very busy. Every day, many people go to treat and change dressings. The workload of the investigation is too great."

Furthermore, we discovered that the lock on Chen Zhaohua's consultation room door was undamaged, and no valuable traces were found inside. This indicates that the perpetrator was a seasoned individual who not only prepared thoroughly but also possessed a certain level of skill in handling traces. I judged that it was not the work of ordinary Green Gang members, but rather the work of specially trained agents. Therefore, I screened all the personnel who stayed at headquarters that night. However, most of the staff at our special agent headquarters were from the Central Bureau of Investigation and Statistics (Zhongtong), and they were all likely to have received such training. I narrowed down the number of such people to thirty-three.

Of these thirty-three people, nine might have had access to information about Deputy Director Wang's arrest. These were all members of the interrogation department and the action team, but they all had witnesses to testify against each other that night, so they didn't have time to go to the infirmary to poison him. From their conversations, I couldn't find any inconsistencies at the moment.

Although Luo Xingchao followed Ning Zhiheng's instructions and did not deliberately frame anyone, such a long investigation should have some results. If there were no results, it would easily arouse suspicion. Therefore, he still selected several suspects to report to Li Zhi.

Li Zhiqun listened very carefully and nodded. From these analyses, it was clear that Luo Xingchao had put in a lot of effort. The workload of this screening work was considerable, and it was already quite good that he had been able to do this.

He pondered for a moment and then said, "If it's about poisoning the infirmary, it won't take long, probably only about twenty minutes. The mole can just find an excuse to leave for a while and complete the job. So, there's almost no point in cross-examination. Let's focus on these nine people and continue the investigation."

Luo Xingchao had no choice but to nod in agreement, and then asked, "Director, when I spoke with Director Zhang today, he said that on the night of the 29th, he was on duty alone in his office, handling some official business. However, no one could vouch for his whereabouts all night. Later, he said that he was organizing materials and formulating an action plan, which has been submitted to you. I would like to know if this is true?"

Li Zhiqun nodded upon hearing this and said, "It is true. He made some gains in those two days, so he was very confident and wanted to carry out a plan. Later, he handed the plan to me, but it was quite difficult and not an easy thing to implement. In addition, given the current situation of our Special Agent Headquarters, it was really difficult to take care of it. I planned to carry out this plan after a while, so it has been shelved. What, do you suspect it is Zhang Jingyao?"

"No, no, Director, you misunderstand. I have no doubt about Director Zhang. It's just a necessary procedure during the investigation. I'm here to verify with you. To be honest, I'm not entirely sure if my judgment and the direction of the investigation are correct. I can only give it a try. I hope you're not misled by my judgment."

Li Zhiqun laughed heartily upon hearing this. He was quite satisfied with Luo Xingchao's caution. It must be said that this person was meticulous in his work, skeptical of everything, and did not blindly overestimate his own strength. There are truly not many agents with such a clear understanding.

He nodded and said, "Zhang Jingyao's history is very clear. He is a veteran agent of the Central Bureau of Investigation and Statistics (CBIS). Logically speaking, given the long-standing irreconcilable relationship between the CBIS and the Military Bureau of Investigation and Statistics (MBIS), it is indeed unlikely that he is an undercover agent of the MBIS Intelligence Section. However, there is always a chance of something going on. You cannot give him special treatment. You still need to investigate where necessary. I have said before that this mole should be someone close to me, so no one can be an exception!"

"Understood. I'll do some more work and see if I can get anything out of it," Luo Xingchao immediately nodded in agreement.

Li Zhiqun sighed deeply and continued, "Xingchao, you don't need to be under too much pressure. As the saying goes, man proposes, God disposes. This time, the difficulty is indeed quite high, which is understandable. The Shanghai Intelligence Section is no ordinary intelligence agency. This time, I have finally experienced their methods firsthand. When they strike, it's a thunderous blow that almost destroyed me and the Special Agent Headquarters. I am truly terrified. I won't be able to eat or sleep peacefully until I find this mole!"

Luo Xingchao quickly nodded and said, "I understand. Please rest assured, Director, I will do my best to complete the investigation and find this mole!"
