Torture during interrogation is indeed brutal, but also very necessary—this has always been the case, both in ancient and modern times, in China and abroad. All that talk about winning people over with virtue is just playing the lute to a cow when it comes to those vicious criminals. Only through both physical and psychological torment can these people be made to comply. However, laying hands on a minor went against John Harris's principles. But he couldn't stop David Clark from doing it, so he simply walked away.

　　As the soundproof panel dropped, the room instantly darkened. A powerful desk lamp on the table shone directly onto William Carter's face, the scorching light so intense that William Carter couldn't open his eyes. But soon, William Carter adapted to the glare, squinting to see David Clark holding something that looked like a flashlight, jabbing it toward him.

　　Although it looked like a flashlight, the crackling blue spark at the tip made it clear that it was definitely not for illumination. With a quick thought, William Carter realized it must be a stun baton.

　　“Bzzzt…” David Clark directly jabbed the stun baton into William Carter's lower abdomen. Over two million volts of high-voltage electricity instantly struck William Carter. “Ah…” William Carter felt a numbness all over, his muscles spasming rapidly, his entire body instantly losing all control, and he couldn't suppress a low cry. But in the next moment, the Vajra Ming King Technique within him activated on its own, a surge of heat coursing through his body in an instant, and all the abnormal sensations disappeared immediately.

　　Seeing that William Carter only cried out once and then had no further reaction, David Clark was startled. Could he have electrocuted him to death? That would be a big problem. Just as he was about to reach out and check, he saw William Carter's squinting eyes glaring fiercely at him, and he immediately became furious—this kid still had plenty of spirit. Without hesitation, he shocked him again, but this time William Carter didn't even make a sound.

　　After Samuel Bennett forcibly enhanced William Carter's physical abilities, this kind of electric shock was no longer a threat to him. It was only the first shock that felt uncomfortable, but under the regulation of the Vajra Ming King Technique, even that discomfort vanished immediately. By the second shock, William Carter's body had already developed a natural resistance to the current, and he felt almost no negative effects.

　　A two-million-volt high-voltage shock like this would be enough to send a strong man into convulsions and unconsciousness, and those with weaker constitutions could even be at risk of death. But William Carter acted as if nothing had happened, and this ease was not something that could be faked. David Clark shocked William Carter twice, and seeing that he had no normal reaction, he felt both shocked and delighted. Shocked at how bizarre and abnormal William Carter's constitution was, but delighted because this extraordinary display suggested he had some connection to that gunshot-immune, monstrous killer.

　　David Clark excitedly rubbed his hands together. After twenty years as a detective, he had seen all kinds of tough guys, and even the hardest men could be reduced to a puddle, crying and confessing. “Little Smith, go get the tools. We're putting on a real show today…”

　　Torture during interrogation has a recorded history of over two thousand years in China. The various methods passed down from ancient times were extremely cruel, but in the past hundred years, as human rights have improved, those inhumane methods have been abolished. In this day and age, torture is already an illegal practice.

　　This has led to torture methods becoming increasingly covert and systematic. The current goal of torture is to use various physical and psychological means to break a person's resistance. For example, the simplest method: not allowing rest. This method works slowly but is extremely effective. Almost no one can withstand seven days of sleep deprivation. That kind of unbearable suffering can even destroy a person's sanity. Even if someone manages to endure it, their mind will be a blank, incapable of thought, and they will answer any question asked of them.

　　However, due to time constraints, this method was not suitable for the current situation. Therefore, the methods David Clark prepared for William Carter were all extremely vicious: “Ice and Fire Nine Layers of Heaven,” “Flash Man,” “Thousand-Layer Cake,” and so on. All sorts of tortures involving heat, cold, pain, and itching were used, and even with William Carter's abnormal constitution, he still suffered quite a bit.

　　But with the Vajra Ming King Technique protecting him, as long as he experienced each method once, it would have no effect the second time. Through these repeated torture sessions, William Carter gradually discovered the various wonders of the Vajra Ming King Technique and gained a preliminary understanding of his current body.

　　Meanwhile, David Clark always had his reservations and didn't dare to actually kill him. After seven hours, the five police officers conducting the torture were drenched in sweat, but William Carter still hadn't said a word. His gaze only grew colder and more piercing, making David Clark feel increasingly uneasy.

　　“Boss, what should we do?” a young officer asked. David Clark was getting more and more ruthless, and the others were starting to get scared. This officer was the first to lose his composure and hurriedly asked while taking a smoke break in the corridor. David Clark stubbed out his cigarette on the ground with a hard twist of his foot. “What should we do? Keep going! I don't believe he's made of iron…”

　　At the same time, a Tianjian-3 supersonic fighter jet landed at the Ancheng military airport. Thirty minutes later, James Thompson, wearing the rank of major general, arrived at the Ancheng City Police Department, accompanied by the commander of the 36th Division of the Ancheng garrison.

　　“Ministry of Defense Class-A secret order: Citizen William Carter, age 18, ID number XXXXXXXXX, due to involvement in important national defense security matters, Major General James Thompson of the General Staff Intelligence Group is specially dispatched to take charge of all related affairs…”
