"Thank you, thank you. I, Du Guangyuan, will never forget your great kindness. From now on, I will definitely reform and comply with the arrangements of the office." If it were someone else making this promise, Du Guangyuan might hesitate a bit, but through this period of understanding Pei Yan, he knows that Pei Yan doesn't make promises easily. Once he says he'll do his best, he will definitely try his best. Hence, Du Guangyuan continues to kowtow on the ground with sincere gratitude.

"Alright, get up. Wanting to rescue your son relies not only on us but also on yourself! You should know why you've been called in. Whether you can ask what I want to know, ask if your son is alive or dead, where he is, depends on whether you can achieve what you boasted before." Pei Yan steps back and supports Du Guangyuan, hinting as he prepares to kowtow again.

"I understand, I understand." This time, Du Guangyuan did not continue kowtowing, instead, he wiped the blood off his face and turned to look at Little Vlad, his eyes full of resentment and maliciousness.

What followed was Du Guangyuan's personal showcase. He first got up, walked to the side, used clean water to wash his face, and after wiping off his face and severed ear with a towel, he put the severed ear against the wound. As Pei Yan said, with his ability, the blood threads at the wound connected to the severed ear, almost effortlessly merging the two perfectly as if they had never been separated.

After tidying up himself, Du Guangyuan moved a table from the corner of the room and placed it not far from Little Vlad. Then, under the curious gaze of Pei Yan and Zheng Jia Ru, he took a leather bag out of his ring and from the bag took out various bottles and jars. Then, like a doctor about to perform surgery, he put on leather gloves and brought out a syringe, surgical tongs, a scalpel, and other tools.

"What is he going to do?" Zheng Jia Ru leaned beside Pei Yan, asking with curiosity.

Pei Yan shook his head, equally puzzled, "I don't know. He was kept by the office initially because he claimed to have methods specifically to deal with the Blood Race. He was preparing for situations like this. Besides, he proved in the individual match that without the blood toxins he provided, we wouldn't have been able to make Little Vlad reveal her true form. But that blood toxin could make Little Vlad's body lose control. However, to make her completely yield and say what we want to know might not be achieved. Let's see. I also want to know what he can really do."

While the two were speaking, Du Guangyuan had completed his preparations. He turned his head towards Pei Yan and respectfully asked, "Mr. Pei, could you both trouble yourselves to hold her down?"

"Oh, alright! No problem." Pei Yan readily agreed. He and Zheng Jia Ru each took a side, pinning Little Vlad against the wall. Little Vlad glared at Du Guangyuan with disgust and anger as he held a syringe with a sinister smile and walked towards her. Her arms struggled incessantly but her body couldn't break free, causing her to exclaim in fear, "What are you going to do! Get away! Stay away from me, you despicable bug."

Du Guangyuan turned a deaf ear to the curses from Little Vlad and even endured her kicks with gritted teeth. With Pei Yan's help, he inserted the syringe into Little Vlad's vein, drew out a syringe full of blood, and then turned back to the table. 𝒇𝙧𝙚𝓮𝔀𝓮𝒃𝙣𝓸𝒗𝒆𝒍.𝙘𝒐𝒎

"Is that it?" Zheng Jia Ru watched as Du Guangyuan injected the extracted blood into different glass bottles and asked puzzled.

"Mm, this is just the first step. Just wait a bit longer, wait a little longer and it'll be done." Without turning his head, Du Guangyuan stared intently at the reactions inside each glass bottle. Seeing that there was no need to continue holding Little Vlad, Pei Yan released her and walked beside Du Guangyuan to see what he was doing.

Upon closer inspection, Zheng Jia Ru became extremely nauseated. Du Guangyuan observed the changes in every glass bottle, sometimes injecting some unknown reagents into certain bottles, sometimes drawing fresh blood from his own body and injecting it into them. In the end, he placed some unidentified granules into certain ceramic bottles. When Zheng Jia Ru crouched down to observe the changes inside the bottles closely, he discovered those granules were alive. Upon contact with the liquid in the bottle, they began to hatch and turned into wriggling, disgusting maggots.

Seeing this scene made even Pei Yan, seasoned and experienced, feel his scalp tingle. This reminded him that this seemingly amiable, subservient person before them had once been a powerful figure in the Southeast, invoking a sense of vigilance towards his methods.

Du Guangyuan was well aware of Pei Yan's concern but was indifferent. Having defected from Divine Desire and being pursued relentlessly by the Vlad family, his choice to take refuge with the investigative office showed he was prepared to linger in prison for the rest of his life. However, Little Vlad's words today gave him new hope, the hope of seeing his son and witnessing his bloodline continue.

For this goal, he was willing to give everything, even his own life! After all, he had lived enough anyway.

After a while, once the first reagent bottle had fully merged, he picked up a syringe and drew out the liquid inside. Seeing his actions, Pei Yan and the others knowingly went to Little Vlad's side and secured her once more, watching Du Guangyuan inject the liquid into Little Vlad's body.

After completing their tasks, the three returned to their original positions, watching as Little Vlad, who had been tormented back and forth, appeared on the verge of collapse. Time ticked by as the four stared at each other. After more than ten minutes, Zheng Jia Ru saw Little Vlad remain unresponsive and asked impatiently, "Are you sure? All this flashy stuff and she's not reacting at all?"

"Just wait a moment longer, wait a moment longer!" Du Guangyuan said, glancing at his wrist to find the watch he was wearing had shattered during the fight. Pei Yan interrupted, saying, "It's been thirteen minutes and forty-six seconds since you finished the injection."

"That's precise." Du Guangyuan smiled and patiently explained, "We need to wait another fifteen minutes. This is different from the blood toxin I used on you in the ring that day. Strictly speaking, that can't be considered blood toxin, but rather more like our hormones, just more stimulating. It can quickly activate the intrinsic blood essence in a weakened Blood Race individual, causing them to reveal their true form, unable to control their abilities and thereby exposing themselves. The injection this time is merely the primer for a series of blood toxins to follow. It needs to slowly permeate every part of her body before it can take effect, so more time is required."

"You're the expert, you make the call!" Since they chose him to act, Pei Yan gave him a certain level of trust. Hearing his explanation, Pei Yan didn't rush and instead dialed Jiang Feiyang's number, laughing, "Is your injury okay? If so, come down quickly! Grab some food when you come down. We've been down here all afternoon, and everyone's hungry. Also, bring Gu Chu and Director Mei over! There's likely going to be quite a show down here."

This phone call not only summoned the three he called but also brought most of the male team members who were interested in seeing the spectacle, except for a few females who weren't interested in the interrogation scene. In an instant, the originally spacious basement became crowded.
