"First, the gold must be given to them. Once they get the gold, they will start to transport it. Only by seeing how it moves can we follow the clues... Secondly, the gold must be marked so that we can find the people who have come into contact with the gold... Finally, by identifying all the people who have come into contact with the gold, we can find out the route of the gold's movement and find evidence of the Shen family's crimes!"
Su Jinyu looked at him quietly, with a hint of curiosity in her voice, "How do you mark gold?"
Zhou Youchen had thought of this a long time ago.
In modern times, just install a tracker.
But there are many other means of tracking.
"There are four methods of labeling nowadays: fluorescent mineral labeling, radioactive tracing, bio-enzyme labeling, and odor labeling. Radioactive tracing requires professional equipment and is easy to expose actions; bio-enzymes are concealed, but the detection conditions are harsh, and odor labeling is easily disturbed by the environment."
“So we can use fluorescent mineral markers, which are transparent wax coatings of mixed fluorescent or baryte mineral powders on the gold surface. These minerals are colorless under natural light, but under a magnesium lamp, which we call a black light, they will emit a blue-green fluorescence.”
His voice was clear and fluent, as if he was describing a plan that he had already mastered.
"To be on the safe side and ensure that the gold can be traced, you can also add a scent marker. Apply a mixture of vanillin and beeswax on the surface of the gold. Vanillin has a strong and lasting milky scent, while beeswax can delay evaporation. To enhance concealment, vanillin can be mixed with camphor to mask the real smell, so that only hunting dogs can recognize it."
Su Jinyu was stunned for a while. She didn't expect that he could come up with such a comprehensive solution in such a short time.
She coughed twice, trying to hide her surprise.
"Then you go and make the arrangements. The gold is still in the car."
Because of the kidnapping, she forgot the gold in the car.
Zhou Youchen nodded and said, "Maybe he can come later today. Ask him to come and get the gold tomorrow."
"good."
After Su Jinyu finished speaking, she raised her chin towards the window and looked at him with a hint of teasing in her eyes: "Go away."
It is hard to believe that the bridge was dismantled so quickly after crossing it.
Zhou Youchen sighed helplessly, with a hint of bitter smile in his sigh.
He walked to the window, very dissatisfied with the behavior of climbing through the window.
Looking back: "I love to climb windows."
There was a hint of complaint in his voice, and then he obediently climbed out the window and left.
His figure flashed past the window, leaving Su Jinyu in the room trying to hold back her laughter.
She thought this person was very cute.
Coming out of the study, Su Jinyu looked calm and said directly in a crisp and clear tone: "The gold has been collected. It will take some time to deliver it. You can come and pick it up tomorrow."
She raised her chin slightly and looked at Shen Jingan calmly, her whole body exuding an unquestionable aura.
By now Shen Jing'an had calmed down from his recent rage and returned to his usual calm demeanor.
He pursed his lips tightly, a trace of joy still lingering in his eyes, and turned to leave, obviously wanting to stay here longer.
Seeing this, Su Jinyu opened her red lips and said, "Wait a minute."
"What else?"
Shen Jingan stopped, leaned slightly to the side, frowned slightly, and had a hint of impatience on his face.
Su Jinyu said slowly, "You can go first. I want to talk to Sister Jing."
As she spoke, she cast her gaze towards Shen Jing, who was standing aside with a confused look on his face. The corners of her mouth slightly raised, revealing a meaningful smile.
Upon hearing this, Shen Jingan immediately turned around, his eyes full of vigilance: "What do you have to talk about with her?"
Shen Jingbo himself also looked bewildered, with doubt in his eyes, and he secretly thought that he had nothing to talk about with Su Jinyu.
She bit her lip subconsciously and nervously tugged at the corner of her clothes with both hands.
Su Jinyu smiled, with a hint of mystery in her smile: "Do you want to hear girls' daily conversation?"
Shen Jing'an snorted lightly, a sneer came out of his nose, and he turned around and strode out.
Shen Jing had extremely complicated feelings towards Su Jinyu. He envied her for being in a high position and holding power, but he also hated her usual condescending and bossy attitude. He even had a little fear of her deep in his heart.
At this moment, she was sitting on the sofa, her body slightly stiff, looking uneasy.
Her eyes looked around anxiously, her hands clenched tightly together, and her knuckles turned slightly white.
"Sister Yu, what's the matter?"
Su Jinyu waved his hand, signaling everyone to leave.
When they were the only two people left in the room, she tilted her head slightly, staring at Shen Jing closely with a hint of inquiry in her eyes: "Did you find anything interesting when you came to my place today?"
Shen Jing was stunned for a while, and then his originally nervous expression relaxed a little, and a playful smile appeared on his chubby face: "Sister Yu, everything about this is good. This house looks big, but the things used in it are very exquisite... very beautiful."
As she spoke, she looked around the room with a hint of envy in her eyes.
Su Jinyu nodded seriously. This house was arranged by Aunt Wu herself. Every item was carefully selected and completely in line with her wishes, carrying many precious memories.
She raised her eyebrows and asked, "Still?"
“…”
Shen Jing looked confused, but he understood what she meant.
She blinked, her eyes full of confusion, her mouth slightly open, but she knew what to say.
Seeing her answer, Su Jinyu pointed outside the house, his eyes became sharp: "Do you know the man who just fought with Shen Jingan?"
She stared at Shen Jing closely, not letting go of any change in his facial expression.
As soon as he finished speaking, Shen Jingbo felt as if acupuncture points were pressed and his body instantly became stiff.
Her eyes flickered and she lowered her head subconsciously. She didn't dare to look directly into Su Jinyu's eyes and denied in panic, "I don't know him."
"Do you really know him?"
Even though Su Jinyu was sitting in a wheelchair, the powerful intimidation emanating from her still made Shen Jing tremble with fear.
"I... 놊..."
Shen Jing stuttered, unable to speak complete sentences, and kept gesturing in front of him with his hands, trying to hide his panic.
"Oh……"
Su Jinyu chuckled and interrupted her denial, saying lightly, "Zhou Youchen is a good-looking guy. There are many celebrities in Qianjiang who know him. Jing, your best student Luo Ling, the only daughter of the director of the Civil Affairs Department, is pursuing him."
"I... I know."
Shen Jing shook his head in panic, his brain shaking like a wave drum.
Her cheeks flushed slightly and beads of sweat appeared on her forehead.
Originally, Su Jinyu only suspected that it was Shen Jing who tricked Zhou Youchen into the room on the wedding day. Now, seeing her surprised expression when she saw Zhou Youchen at the door, she was also hiding her panic at this moment.
She had already concluded in her heart that the person who deceived Zhou Youchen was Shen Jing, and Wang Manrou, with her identity, could never get in touch with Zhou Youchen.
