Qin Lun remembered in a trance that he once had such a copper key, which was a piece of copper that he had picked up from the garbage, and his dirty appearance made it impossible to tell what it was.

Qin Lun used the little free time he usually had to polish this piece of copper until it had the prototype of the key, and then used the iron wire he picked up to rub out the lock teeth little by little.

His purpose was simple, to use this bronze key to open the iron lock that tied his sister's neck. It's just that he was very careful and never dared to let his adoptive parents, Mr. and Mrs. Foster, discover his secret.

The Qin Lun siblings' biological parents were killed in a car accident, and then they were adopted by the Fosters.

Mr. and Mrs. Foster are a pair of European and American immigrants, and when they first adopted Qin Lun's siblings, Qin Lun, who had a superior IQ, keenly saw that they had a different purpose. But the reason why he didn't turn down the Fosters at that time was because he thought that the two were just coveting orphan relief from the Welfare Department, and he didn't realize that they were not good people at all.

After the Qin Lun brothers and sisters were adopted, they did live a worry-free life in the early days. However, when the staff of the child welfare agency gave up on observation, the Fosters finally showed their true colors.

The nightmare of the Qin Lun siblings began, the two siblings were abused one after another, and even in order to control them, the two couples usually only let one of them be freed, and the other was chained to the basement like a dog.

If this is all the time, Qin Lun may continue to endure humiliation and steal his life, and wait for his sister to grow up a little before finding a way to escape. However, this idea was shattered when he overheard the Fosters' bedside conversation late one night.

The couple didn't have much conversation that night, but with Qin Lun's IQ, many things could be inferred by themselves.

Mr. and Mrs. Foster turned out to be a pair of professional con artists who had already used false identities to adopt orphans on more than one occasion.

They wandered around the Huaxia District, and each time they adopted a pair of orphans, they would stay quietly for a while. When the welfare agencies give up tracking, they kill the orphans and then leave the area under the pretext of job transfers.

This process can be as short as a few months or as long as a year or two. Unlike traffickers, who resell children, the orphans adopted by the Fosters end up brutally murdered. Because of their concealed methods, until the adoption of Qin Lun's brothers and sisters, neither the police nor the child welfare agency was aware of it.

The real reason why the Fosters did this is still unknown.

It wasn't until Qin Lun entered a heavy prison that he got some speculation from a psychology expert, which was why Qin Lun first studied psychology.

At that time, in order to open his mind, the psychologist carefully analyzed the behavior patterns of the Fosters and got some guesses from them.

The expert believes that the couple, who go by the pseudonym Foster, may also have been orphans during their childhood and had had severe psychological trauma. This trauma may be that he has been bullied by other orphans, and as an adult, he has always hated being an orphan.

Every time they adopt a pair of orphans, they fantasize about their childhood peers who bullied them, and then vent their anger on the orphans, and use this to take revenge on the welfare institutions and orphanages that did not rescue them.

This purpose was indeed fulfilled after the death of the Fosters.

As more and more pseudonyms and crimes of the Fosters were exposed, the child welfare institutions and orphanages that had handed over the orphans to the Fosters for adoption were almost all sprayed into scum by the local media.

From Qin Lun's listening to some conversations between the Fosters that night, he knew that time was running out for his siblings, because investigators from the local child welfare agency had not come to visit for a long time.

Qin Lun began to polish the copper block all night, the slender iron wire and the sharp teeth of the key grinding his palm again and again. Little by little, the boy's blood seeped into the bronze key, leaving behind many tiny stains that looked like rust spots.

These stains were exactly the same as the "rusty spots" of the copper key in Harry's hand now, and the blonde boy had the same experience as Qin Lun.

Although Harry's key is not to free his sister, but to free the black slaves of the manor, the actual effect is the same.

In the era when the Qin Lun siblings lived, he only needed to escape from the Foster couple's house and find the police station to be rescued. The Harry siblings are different, they are in an era and region, and it is not enough to just escape.

Hundreds of years ago, the United States was a large colony, and there was no social welfare agency for orphaned brothers and sisters. What's more, Wilson Manor is rich and powerful, and if it is not destroyed first, the Harry siblings will still not be able to escape.

"Brother, I'm late!" Elaine touched the bronze key, large tears rolling down her face, and buried her head in Harry's chest, her shoulders trembling slightly.

"It's not too late, if only you could come back safely from London!" Harry patted Elaine on the back with relief, but Qin Lun, who was deep in his body, felt a little strange. He had a feeling that the words of the little girl in Harry's arms seemed to mean something else.

Just as Qin Lun was thinking about that sentence, a fierce quarrel came from outside the living room door. The hugging Harry siblings parted as if they had been electrocuted, and Harry looked at the door with panicked faces.

"I said I didn't have a bad relationship with Diana!" The door to the living room was slammed open, and a muffled male voice rang out.

"Hehe, do you expect me to believe it? Thomas! Another somewhat shrill female voice sounded behind the man.

"Hmph, so what, don't think I don't know you're ...... London," a mocking sneer sounded from the man's mouth, but it came to an abrupt halt as he saw the Harry siblings in the living room.

Following Harry's gaze, Qin Lun saw the long-known Wilson couple.

Thomas Wilson was a middle-aged man in his forties, with a burly build, a well-trimmed beard, and a very dignified middle-aged gentleman.

Kayla Wilson was a fat middle-aged woman with a fur scarf on her hand, a face full of flesh, small eyes, and a sarcoma on her nose.

Not only is the appearance ugly, but also there is no noble lady's temperament, if you strip off that expensive dress and replace it with burlap, it is more like an ugly village woman who sets up a stall at the entrance of the vegetable market.

Although Qin Lun had never seen Diana, since the charming Susan was very similar to him, he could fully imagine what choice the Sir Wilson in front of him would make.

No wonder Sir Wilson has been married to her for so many years, and has no real children. It was hard for Qin Lun to imagine what kind of mood Thomas Wilson, who was still heroic in appearance, had to endure in order to be false and ashen to her in bed.

In this way, it can also be seen that Wilson was embarrassed to marry this merchant's daughter.

"Get out!" The two couples who saw the Harry siblings were full of indifference, and they did not feel the slightest embarrassment of being bumped into by their children, as if in their eyes the Harry siblings were just a pair of pets.

"Yes, Father!" Harry bowed his head obediently and pulled his sister towards the door.

"Smack!" As soon as the two children walked up to Wilson, they saw a sneer on the middle-aged man's face, and without warning, he slapped Harry to the ground.

Qin Lun's vision swirled with Harry, and there was a burst of fury in his heart, and he even felt that this slap was on his face.

"Brother!" Elaine cried and threw herself on Harry, resting her head on the boy's shoulder. From this angle that no one could see, Elaine had no tears on her face at all, just a gloomy expression that seemed to be dripping.

Like Qin Lun, Qin Mei seems to have been opened to the darkest corner of her heart at this time, and she can't help but substitute herself for the role of Elaine Wilson.

"The next time I see you with your sister without consent, I'll break both of your legs!" Thomas Wilson's cold words made both siblings stiffen.

"Hey, what is this?" Kayla Wilson's tone was calmer than before, not angry at all at Harry for being beaten, she picked up a bronze key from the ground, frowned at the man and asked, "The key you gave him?" ”

"Huh? Let me see! Looking at Harry's face, which instantly turned white, the middle-aged gentleman raised his eyebrows and took the poorly made copper key from his wife's hand, "I didn't give it to him, I don't know where this little bastard stole it from, it seems that I want to ask Parker." ”

The man walked to the corner of the living room and pulled a thick rope behind the window curtain.

Hearing the summoning bell, Old Parker soon came, took the bronze key from the man's hand and examined it carefully. At this time, the Harry siblings had shrunk into a ball of fright, and their whole bodies trembled as they looked at the three people in front of them.

"This is ......" Old Parker's face suddenly changed, and when he took off a bunch of keys from his waist, his expression became more and more ugly.

"Master, this seems to be the key to the manor's 'barn'!" After a long time, Butler Parker finally wiped the cold sweat from his forehead and said hesitantly.

"Barn? Which barn? The middle-aged gentleman's face also changed, and his eyes glared at the old butler fiercely.

"Yes...... It's the barn where the slaves were held! Old Parker's head was getting lower and lower, and he obviously knew it was a terrible mistake.

"Smack!" Thomas Wilson's slap slammed into the old butler's face, staggering him, and five earthworm-like red marks quickly bulged up on the old man's face.

"You old shit, this little bastard copied such a key, you don't even know it!" The cold light in the man's eyes almost turned into substance, and he roared and roared, "Go, call the overseers of the manor to assemble, it's time to clean up those again!" ”

"Yes, sir!" Old Parker almost crawled out of the living room.

"Hehe, it looks like you're dazzled by that little bitch of Diana, and you don't even know that the black slaves in the manor are going to go violent~!" Kayla, the fat woman, covered her mouth and smiled widely, sneering at the huddled Harry siblings.

"However, I didn't expect my good son to have this ability, much better than his previous 'brothers'!"
