Chapter 724 Sister...Sister...

The teenager grabbed Hexi's hand, brought her palm close to his mouth, and then blew lightly.

Hexi's entire body froze completely, looking at the boy in front of him in disbelief.

The corners of the boy's mouth twitched stiffly, as if he were smiling, but it turned into a weird muscle twitch.

Seeing that Hexi still didn't smile, he thought she was still in so much pain, so he grabbed her hand reluctantly and blew lightly again.

"Xiaochi--!" Hexi let out a cry that was almost whining, and suddenly reached out and stroked the boy's face.

She stared at the boy's face as if in a daze, inch by inch, not letting go of every detail.

The more she looked, the more she felt like it.

Eyebrows, facial features, all seem to be like her younger brother Koike when he grows up.

It's not Nalan Hexi's younger brother, but the younger brother Xiaochi who lived with her in the orphanage in his previous life!

Hearing her cry, the young man seemed to be stunned, and a confused and stunned light flashed in his eyes.

Yingzi's eyes also stared blankly at Hexi, and then, like a ghost, the boy opened his mouth and shouted out two words in a broken and chaotic voice, "Sister...Sister..."

Hot tears fell from Hexi's eyes, dripping wet her clothes, but she didn't notice it.

She couldn't tell whether the tears belonged to Hexi or Nalan Hexi, but that elder sister stabbed the softest part of her heart.

Hexi took the boy's dirty body into his arms, and whispered in a trembling voice, "Xiaochi... Xiaochi..."

The little figure who stood in front of her again and again to protect her.

The younger brother who was willing to go into a hellish laboratory for him.

It was the only relative she had in her previous life, and the one she could never have again.

But now, Xiaochi appeared in front of her now.

No matter whether the young man in front of him is Nalan Hexi's younger brother or her Hexi's younger brother, in this life, she will definitely protect this young man and prevent him from being hurt in the slightest.

When the young man was held in his arms by Hexi, he panicked for a moment and instinctively wanted to escape.

But slowly, the familiar aroma of Hexi's body entered her nose, a smell that made her yearn and miss.

The boy's nervous eyebrows slowly relaxed, he obediently leaned his head on Hexi's shoulder, and his throat made a comfortable sound like a beast being smoothed.

He even turned his head to the side because of excitement, and lightly licked the skin on the side of Hexi's neck to express his intimacy and love.

Nangong Yu, who has been watching by the side, has been hypnotizing himself that this is Nangong Yu, who is not allowed to be jealous and angry with Hexi's younger brother. At this moment, he can't bear it anymore.

This little pervert, even if he threw himself into Xi'er's arms (obviously Hexi had pulled him in), he dared to lick Xi'er, was he impatient?

Nangong Yu took a step forward with a cold face, clasped the boy's neck with one hand, and took him out of Hexi's arms.

As soon as the boy was pulled away from Hexi, his nerves were immediately tense, and his face was full of fear and vigilance.

However, when he felt the powerful aura emanating from Nangong Yu's body, he immediately became quiet again.

It's just that the long-term abused life made him tremble and let out a low, sad whimper whenever he felt the danger.

Hexi immediately stood up nervously and shouted, "Nangong Yu, what are you doing? Will you hurt him like this?"

Nangong Yu frowned, looking at the boy in his hands with even more unkind eyes.
