"Hey, officer sister, don't get upset, okay? Leave it to me!" Lin Mu grinned at Qi Manlin.

Qi Manlin sat down angrily, handing over the matter to Lin Mu. Lin Mu took on the task without hesitation. Dealing with minor characters like Shen Si and Qi Hong was a breeze, just like how the big zombies of the Zombie Gang confessed their crimes to Lin Mu in the police station. Handling Shen Si and Qi Hong was a piece of cake.

Lin Mu was curious to see just how strong-willed these two were. Of course, Lin Mu wasn't about to disgracefully abuse his power with private torture—none of that shocking the body with electric batons, dripping wax on faces, or force-feeding chili water. Those lowly methods weren't his style!

To handle two minor figures like Shen Si and Qi Hong, only two needles were needed! The mighty "Diamond Sutra," the pinnacle of martial arts—it wasn't just that Shen Si and Qi Hong couldn't withstand it; even super experts like Jinge and Luo the Mute from the underworld couldn't either. It would leave people itching with an indescribable feeling!

Lin Mu grinned, and in the next second, two silver needles pierced into their chests! Shen Si and Qi Hong shivered simultaneously, soon feeling as though something was flowing through their blood vessels, spreading all over their bodies like thousands of ants. An unprecedented itch and pain swept over them! Both of them began to scratch frantically!

But scratching was ineffective; this itch was coming from inside their blood vessels, and it was getting stronger!

"Ah!" Shen Si and Qi Hong cried out in discomfort, their bodies reddened from scratching, but it was still no use—they would have scraped their skin off to get to the feeling inside.

The feeling was excruciating; their whole bodies itched, but they couldn't find the right place to scratch. As time passed, Shen Si and Qi Hong went mad; the sensation was unbearable—not painful, just extremely itchy, but the itch wasn't on the skin's surface; it was within!

"Ah!" Shen Si and Qi Hong screamed once again, driven to the point of bashing their heads against the wall!

Bang, bang! Shen Si and Qi Hong kept ramming their heads into the wall, but even the pain couldn't mask that terrible itch!

To the human body, to cover one pain, a more intense pain is needed, and now Shen Si and Qi Hong were clearly using physical pain to cover that itch; the feeling was unbearable. Comparatively, they'd rather have Lin Mu beat them up—it was worse than pain!

They continued to bang their heads against the wall and punch it, their hands already bloodied, heads bleeding profusely, clearly showing how unbearable it was!

Lin Mu saw they were nearly tormented enough. He knew they felt the itch by now. Then, Lin Mu took out two more silver needles, and with a swish, they were again inserted into their chests, making Shen Si and Qi Hong shiver, with that maddening itch vanishing instantly!

The two sat gasping against the wall, the torment leaving them exhausted, yet feeling unbelievably relieved!

"So, did you enjoy that taste? Now, I'll ask you one last time—will you talk or not? Remember, you'll only get this one chance!" Lin Mu smiled at Shen Si and Qi Hong.

Shen Si and Qi Hong looked at Lin Mu in terror, seeing him as the Devil, sending chills down their spines. They thoroughly experienced that sensation—it was worse than death!

"I'll talk, I'll confess..." Shen Si and Qi Hong finally relented.

"Who orchestrated this?" Lin Mu asked.

"Chen Jinnan from East City Hospital!" Shen Si answered.

"What? It's those doctors? A healer has a parent's heart, yet they're doing this—it's outrageous!" Qi Manlin exclaimed angrily.

However, Lin Mu's interest wasn't in Chen Jinnan. He was just a small character, only a tool. Lin Mu was more concerned about who was pulling the strings behind him—that was the key point!

"Hey, sister, don't get worked up yet; let's figure out the details first!" Lin Mu smiled at Qi Manlin.

Shen Si and Qi Hong shook their heads, "That's all. We were hired by Chen Jinnan. We just followed orders."

"Did you see an old man at the old lady's house?" Lin Mu asked.

"No, when we got there, she was already like that. We just did as Chen Jinnan instructed, caused trouble at the hospital." Shen Si replied.

Lin Mu glanced at them. Since he couldn't get anything precise from them, it was down to Chen Jinnan. Shen Si and Qi Hong were clueless, but Chen Jinnan knew for sure!

"Alright, officer sister, I'm done questioning; take them away!" Lin Mu blew out a puff of smoke.

Qi Manlin arranged for two officers to take Shen Si and Qi Hong out of the interrogation room!

"You big jerk, what do you think about this case?" Qi Manlin nudged Lin Mu, who was silently smoking.

"Things aren't that simple. I suspect the three Grand Hall Masters of Heaven and Earth Society are behind this; it must be related!" Lin Mu stated.

"People from Heaven and Earth Society? Really? Isn't this just Chen Jinnan's business revenge?"

"Hehe, not that easy. How much power does Chen Jinnan have? Without someone pulling the strings, he couldn't do this. Frankly, I hope it's people from Heaven and Earth Society, because this case already constitutes attempted murder—we can use it as an excuse to deal with the Hall Masters!" Lin Mu laughed.

"Use solving the case as an excuse? But there's no evidence right now—how do we handle them?" Qi Manlin asked.

"Finding evidence is easy. Hehe, Shen Si and Qi Hong don't know, but Chen Jinnan surely does. Just find Chen Jinnan, make him reveal everything, and the person behind it will naturally surface!" Lin Mu chuckled.

"Right, how didn't I think of that? There's still Chen Jinnan as a clue—find him and we'll uncover the truth!" Qi Manlin suddenly understood.
