Just as Xiao Zixuan's foot was about to step on the doormat, suddenly a figure rushed out and scooped Xiao Zixuan up around the waist.

"Ah!"

Xiao Zixuan let out a scream of surprise.

The next instant, Lin Chen was holding Xiao Zixuan in his arms.

At this moment, Xiao Zixuan was almost in disarray. What was this situation? She had just arrived home, her sister had tumbled down the stairs, and she herself had been forcefully picked up by a stranger.

The most infuriating part was that the person holding her had his hands placed on her proudest chest.

"Who are you, what do you want, put me down now," Xiao Zixuan bellowed furiously.

Lin Chen, seeing that his good intentions were met with such a poor attitude, was also a bit angry.

He loosened his grip and directly threw Xiao Zixuan onto the ground.

"Thud!" Xiao Zixuan fell squarely on her buttocks.

"Ouch! Why did you let go?" Xiao Zixuan shouted angrily.

"It was you who told me to let go!" Lin Chen said with an innocent face.

"You! Who are you? Why did you hold me? Give me a reasonable explanation," Xiao Zixuan demanded angrily.

Lin Chen snorted coldly, lifted up the doormat, and the sight of sharp steel nails sent a chill down Xiao Zixuan's spine.

If she had stepped on that, her foot would have become a pincushion!

At this point, Xiao Ziting had also risen from the ground, looking extremely disheveled with her hair scattered and her leg scraped, but most importantly, she had just stood up when suddenly feeling a pain in her foot, she sat back down again.

Seeing her sister injured like this, Xiao Zixuan's face suddenly changed, and she hurried over.

"Ziting, how are you?" Xiao Zixuan asked anxiously.

At that moment, Lin Chen walked over and grabbed Xiao Ziting's little foot.

"Hey, what are you doing? Let go of my foot, you pervert," Xiao Ziting said furiously.

"If you don't want to end up crippled for the rest of your life, you better stay calm," Lin Chen said sternly.

Upon hearing Lin Chen's words, Xiao Ziting immediately quieted down.

"Do you know medicine? Don't move it around, this kind of injury needs to be taken to the hospital," Xiao Zixuan said worriedly from the side.

Lin Chen looked up at Xiao Zixuan and said, "Waiting for an ambulance, your sister would miss the optimal treatment time. At best, she'd stay in the hospital for half a year, at worst, she'd end up permanently crippled."

Listening to Lin Chen's words, Xiao Ziting also dared not speak further.

Lin Chen gently kneaded Xiao Ziting's leg a few times.

Xiao Ziting's expression slightly changed; she felt a warm flow entering her body, and the unbearable pain in her foot suddenly became much more bearable.

How could this be possible!

"Bear with it!" Lin Chen said, then suddenly exerted force.

"Ah!"

Xiao Ziting cried out in pain, with large beads of sweat dripping down.

"Sister, how are you feeling?" Xiao Ziting asked anxiously.

Lin Chen loosened his grip and said lightly, "She's fine now, just avoid strenuous exercise for a few days, and she'll recover quickly."

Hearing Lin Chen's words, Xiao Zixuan finally breathed a sigh of relief.

She helped Xiao Ziting up, initially intending to support her to the couch, but after walking a few steps, Xiao Ziting was surprised to find that her foot didn't seem to be that serious.

Sister, you don't need to help me, I'll try walking on my own.

Xiao Zixuan released her hand, and Xiao Ziting walked a few steps, surprised to find that her feet did not hurt at all.

Seeing Xiao Ziting able to walk, surprise also appeared on Xiao Zixuan's face.

Just now, Xiao Ziting's foot was so swollen she could not move it at all.

But after Lin Chen massaged it briefly and then forcefully twisted it, her foot seemed to be fine.

This time, Xiao Ziting looked at Lin Chen with a bit of astonishment as well.

"Ziting, what happened?" Xiao Zixuan asked.

"Sister, he bullied me, not only did he peek at me changing clothes, but he also snatched my necklace," Xiao Ziting said with a look of grievance.

"Mr. Lin, please give me a reasonable explanation," Xiao Zixuan said coldly.

Lin Chen glanced at Xiao Zixuan and said, "Miss Xiao, please come with me, I have something to tell you."

Xiao Zixuan looked at Lin Chen with doubt, but still followed him to a small room.

Lin Chen took out Xiao Ziting's necklace and placed it on the table.

At this point, the pendant on the necklace had been split into two by Lin Chen, and from inside the pendant, a lot of white powder had been poured out.

"What is this?" Xiao Zixuan asked, looking at Lin Chen with confusion.

Lin Chen said indifferently, "This powder is from a plant called Bai Ku Cao, it's a chronic poison. Although it's colorless and tasteless and you won't feel anything in the short term, if worn for a long period, it can cause respiratory failure and death. I want to know, who gave this necklace to your sister?"

"What?" Hearing Lin Chen's words, Xiao Zixuan's face suddenly changed.

Xiao Zixuan, looking distressed, said, "Someone else gave it to me, then my sister liked it so I gave it to her."

"How did you come by this necklace?" Lin Chen continued.

Xiao Zixuan shook her head: "Impossible, it couldn't have been her."

Lin Chen narrowed his eyes slightly and said responsibly, "Miss Xiao, I must tell you that the person who gave you the necklace is trying to kill you, so no matter who that person is, please tell me."

Xiao Zixuan sighed and said, "This necklace was given to me by my mother."

"Your mother?" Lin Chen frowned.

As the saying goes, even a tiger wouldn't eat its cubs. How could Xiao Zixuan's mother possibly want to poison her own daughter?

"Could you contact your aunt to find out where she bought this necklace, or who gave it to her?" Lin Chen asked.

Xiao Zixuan shook her head bitterly: "This necklace is a family heirloom, I have seen it since I was very small."

What?

Hearing Xiao Zixuan's words, Lin Chen was also stunned.

A family heirloom? How could that be, could the Xiao family have been passing a poisoned necklace down through generations?

Lin Chen became somewhat disorganized in his thoughts as he stared blankly at the toxic necklace.

All clues were broken again. It was highly illogical to suggest Xiao Zixuan's mother wanted to kill her own daughter, so it was certain her mother must not know about the necklace.

"Can the system help me verify the age of this necklace?" Lin Chen asked the popular system.

Soon the appraisal result came out; the necklace had been made one year prior.

Lin Chen's eyes narrowed slightly; it was clear the necklace had been switched. The most likely person who could have switched the necklace would be someone from within the Xiao family.

"So, any ideas?" Xiao Zixuan asked.

Lin Chen nodded and said, "I have some ideas now. This necklace isn't the one you saw when you were young. It has been swapped, meaning it's very likely that someone in your Xiao family wants you dead."

Hearing Lin Chen's words, Xiao Zixuan's face turned grim.
