Once I enter the pass, great Confucian scholars will surely debate the classics for me.

Zhou Qingfeng glanced at Zhiqi and said calmly, "Zhiqi, sit down first and let's talk business."

"Yes, Commander." Zhiqi bowed and clasped his hands in response, then sat down again. However, his expression showed some unease. The punishment had not yet been decided, and he never knew what punishment he would face. His heart was inevitably in suspense.

As for being exempted from punishment, that's impossible.

Because the commander always acted with a clear distinction between rewards and punishments.

Zhou Qingfeng remained calm, slowly taking a sip of his tea: "Jin Wei, what have you found over there?"

Jin Wei took out a prepared report, which detailed the operation.

Zhou Qingfeng took it as usual and placed it on the report written on the instrument.

Seeing this, Jin Wei understood immediately and clasped his hands in a fist and gave a verbal report: "Commander, I led a team to visit hundreds of clinics in the city. Among them, four clinics in the old city suddenly closed down a few days ago."

"Strangely, the doctors and apprentices from all four clinics left the Sword Tower at the same time."

"As if they had made a pact, they all disappeared without a trace."

"What's even stranger is that the doctors and apprentices in these clinics are all locals of Sword Tower. They have no reason to leave Sword Tower City. I immediately became suspicious and led men to break into these four clinics to search them."

"The medicines, food, water, and clothes in the clinic are still there, and there are even dried-up dregs in the medicine furnace. It is obvious that the people in the clinic left in a very hurry. Moreover, all the written records, such as accounts, medical records, and patient lists, have disappeared. Not even a single piece of paper was left."

"This subordinate strongly suspects that these four medical clinics are secretly distributing the Killing Official Pill to specific patients in the Food Fiend Realm for human drug trials. I don't know where they got wind of this, but they destroyed all the accounts and urgently evacuated from Sword Tower City before us. It's as if they received advance notice."

Zhou Qingfeng frowned slightly, thinking to himself that he had gotten one step ahead again.

Once could be a coincidence, but twice is no coincidence: "You suspect there's a mole tipping you off?"

Jin Wei nodded solemnly: "Commander, the Fifth Division of our Censorate operates in secrecy. No outsider could possibly know any information about the case. Only an internal leak could put us in such a passive position."

Zhou Qingfeng calmly tapped the tea table: "Let's talk about the mole after we finish discussing serious matters."

Upon hearing this, Jin Wei nodded slightly: "I searched this place but found nothing. I had no choice but to visit the neighbors and keep asking around. Fortunately, I have a few friends in the city defense army. After carefully inquiring, I learned the direction of one of the clinics outside the city, so I followed it all the way to the wild swamp."

"When we arrived, the doctors and apprentices in the clinic had already met a tragic end. Their bodies had been devoured by the ghoul demons and were completely unrecognizable. However, judging from the fatal wounds left on the bodies, they did not die from the mouths of demons, but were killed by a cultivator at the Fiend Realm with a knife."

“Commander, this is blatant cover-up. I’m sure the people from the other three clinics will suffer the same fate.”

Zhou Qingfeng hummed in agreement: "And then?"

Jin Wei calmly said, "Now that things have come to this, I know there's no point in continuing to pursue this. So I simply led my men back to the city and investigated the backgrounds of the four clinics. We discovered that they were all businesses run by the Cleaver Gang."

"I immediately followed this lead and indeed found something."

"The leader of the Cleaver Gang, Cleaver, also vanished into thin air a few days ago, just like the leader of the White Wolf Gang, White Wolf. Furthermore, the leaders of the Axe Gang and the Butcher Gang also mysteriously disappeared together."

"The leaders of the four major gangs in the old city disappeared at the same time, along with their trusted subordinates. As long as someone was involved in the case of the murder of Guan Wan, the clues we found would be cut off in advance, and the person would simply disappear. It was like a meticulously planned and long-prepared cleanup operation."

"The only thing we know now is that the leaders of the four major gangs in the old city are inextricably linked to the Killing Officials case. All four of them have disappeared, and the evidence has been wiped out, leaving no survivors."

Upon hearing this, Zhou Qingfeng calmly asked, "Have you investigated the patient's case?"

Jin Wei clasped his hands and said, "Reporting to the Commander, Zhiqi and I went to investigate and confirmed that four medical clinics jointly held a banquet to thank their customers at a manor in the wilderness. They invited a group of patients to attend. All of these patients were cultivators at the Food Demon Realm, and without exception, they were all unregistered residents of the Sword Tower."

"Based on the traces left at the scene, I judge that the other party must have used the True Immortal Brew to get all these patients drunk, then put on the old shackles to imprison their magic and supernatural powers, and took this group of people away from the manor."

"There were many footprints at the scene, no less than a thousand."

"Based on the footprints and lingering smell of alcohol left at the scene, we tracked them all the way to the riverbank in the wild. The footprints and smell of alcohol disappeared, which confirmed that the patients who were to be tested for the drug had been transferred to a boat by the other party. We had no idea where they were being transported, because the flowing river water had erased all traces."

Upon hearing this, Zhou Qingfeng clicked his tongue, turned to look at Xiao Hongyun, and said, "I guess you also came up empty-handed. All the clues have been cut off, and you haven't found anything useful, have you?"

Xiao Hongyun spread his hands: "You guessed right. I had someone pass on all the information about drug trials in castles and villages all over the past ten years to me. I've been organizing and filing them these days, trying to find some clues and leads."

"But without exception, all leads have gone cold. Those involved are either dead or missing. The people behind it are quite clever; they have never shown their faces. The ones who are out there doing things are just small fry."

"It seems that the leaders of these four major gangs are all puppets manipulated by the mastermind behind the scenes. Now that the leaders of the four major gangs have all disappeared, they have probably been silenced by the mastermind behind the scenes."

"Old Zhou, let me tell you something you may not like to hear, but at this stage of the case, it's almost impossible to solve it. All the leads have been cut off, and the people involved are either dead or missing. Even if we continue to investigate, it will only be a waste of time and energy, and we will end up with nothing."

"Fortunately, although we did not find out who the other party was this time, our investigation made them feel fear and apprehension. They will definitely not dare to continue testing drugs in the Sword Tower, which can be regarded as eliminating a hidden danger."

"Let's stop here, seal the files, and reopen the investigation if they dare to test drugs in the Sword Tower again in the future."

Zhou Qingfeng stroked his chin, his brows furrowed, and after a moment of contemplation, he said, "It's too early to seal the files now. All the leads have indeed gone cold. The other side is very adept at doing things, leaving us with nothing to investigate."

"However, the other side left us with a new and important clue."

"And this crucial clue lies within our Fifth Division."

Upon hearing this, Xiao Hongyun, Zhiqi, and Jin Wei exchanged glances and all thought of the word "traitor." They then lowered their heads in thought. Indeed, if there was a traitor in five places who was tipping them off, it must be related to the mastermind behind the scenes. Otherwise, it would be impossible to pass on the information so quickly and to do the cleanup work one step ahead of everyone else.

"Old Zhou, you mean we need to investigate the mole?" Xiao Hongyun's eyes were bright and alert, as if he had grasped Zhou Qingfeng's train of thought. However... Zhou Qingfeng's ideas were not so easily seen through.

"Yes, investigate the traitor, we must investigate thoroughly!" Zhou Qingfeng smiled slightly. He wanted to investigate the traitor, but he also wanted to use the opportunity of investigating the traitor to openly and legitimately take action against the Luo family gang.
