"This ......" Li Yuan hesitated a little, but he finally gave Pang Yue a positive reply: "I want to find a way." Pen ~ Fun ~ Pavilion www.biquge.info"

Later that day, Pang Yue was allowed to take a walk in the courtyard, Pang Yue didn't know how Li Yuan persuaded them, but no matter what, as long as they could leave that nasty room.

Pang Yue came alone under the green tree that she could see from the window, this Li Xi was not there, she followed Li Xi's example and stood at the bottom of the tree, raised her head slightly, and let the sea breeze gently brush her cheeks, at this moment, she seemed to feel that she was the only one in the world.

"Sister!" A faint girl passed from behind her.

Pang Yue opened his eyes violently, only to see a familiar figure appear in front of him under a bright sun, "Li Xi!" ”

Li Xi stood in front of her, revealing a row of snow-white teeth, eyebrows like Yue'er hung crooked on her face, Pang Yue walked in front of her with a smile, and gently lifted Li Xi's long black and shiny hair with her fingers, Li Xi's clear and bright pupils could reflect Pang Yue's outline.

"Who brought you here?" Pang Yue took Li Xi's soft and slender hand and sat under the tree.

"My father brought me here." Li hoped that the sister in front of him who was exactly the same as himself had an indescribable dependence in his heart.

"Professor Li?"

"Hmm!" Li Xi's long eyelashes fluttered twice on his face.

"Didn't Professor Li say why?"

"I've always been in poor health, and my father said he brought me here to recuperate."

Pang Yue looked at Li Xi, who was of the same age but very simple, and sighed, she didn't know if she should let her know what the identity of the father in her mouth was, "How is your body?" ”

"Actually, I'm fine, it's just ......"

"What's it?"

Li Xi's cheeks flushed slightly when he said this, "I just heard my father say that I can't have children." ”

"What?" This news made Pang Yue feel a little thunderous, and the words that Chen Chen whispered to her when he left began to appear in her mind began to emerge, is this true!

"Well, other friends have had their periods a long time ago, but I haven't had them, and then my father took me here to check and found out ......"

"What?"

Li Xi put his head close to Pang Yue's ear, "I don't have ovaries." ”

Pang Yue's complexion turned gray in an instant, and he couldn't say a word when he opened his mouth slightly.

Li Xi smiled, "But I think it's good not to have it, at least I won't have a stomachache like them." ”

The smile on Li Xi's face was sincere, she really didn't care about this, just when Pang Yue fell into deep thought, Li Xi asked her in her ear again, "Sister, do you have it?" ”

"Ahh Pang Yue suddenly came back to her senses, she knew that Li Xi was asking if she had ovaries, and Pang Yue, who didn't know how to answer, just nodded, "They said that everything was fine with me." ”

"My sister is normal!" There was some surprise in Li Xi's eyes, but also a little loss.

"Well," Pang Yue didn't know how to comfort this sister, "Do you know why we are so similar?" ”

Li Xi smiled slightly and nodded, "I know, my father told me." ”

"Professor Li told you?" Pang Yue didn't expect that Li Yuan had already told Li Xi her true identity.

"Well, my father said I wasn't my mother's biological daughter."

As soon as Li Xi said this, Pang Yue took a deep breath, it seemed that she didn't know her identity as a clone, "Then did Professor Li tell you who your biological mother is?" ”

Li Xi grinned, "He said that it was a girl he admired when he was young, called Tang Xiuxiu." ”

Pang Yue smiled and nodded.

"Is my sister's mother Tang Xiuxiu?" Li Xi blinked and looked at her with an innocent expression.

Li Xi asked this question, Pang Yue was dumbfounded all of a sudden, how should he answer this question? Who her mother is, even she hasn't figured it out herself.

"What's the matter, sister, why is your face so ugly?"

"Ahh It's nothing. Being called by Li Xi like this, Pang Yue suddenly knew how to answer her question, "I am the same as you, we are from the same person, but we were raised by different people." ”

Li Xi nodded violently, "Father said this is called IVF." ”

"Test tube...... Infant...... Is it? Pang Yue felt that this explanation did not seem appropriate.

"Well, he said that the two of us were formed by splitting the same egg, which was cryopreserved through a special technique after splitting, and then implanted in the wombs of different people to develop into babies."

Listening to Li Xi's words, Pang Yue suddenly felt Li Yuan's strong love for Li Xi, and he actually used an explanation between truth and falsehood to protect her. Thinking of this, Pang Yue showed a bright smile, she seemed to like this sister who was also a clone.

"Lixi!" Li Yuan's voice came from behind them.

"Father." Li Xi heard Li Yuan's voice, and immediately stood up happily and ran towards him like a butterfly.

When Pang Yue saw Li Yuan, he also stood up politely and nodded at him with a smile.

"It's time for us to go back!" He looked at Li Xi who ran towards him with a loving expression.

Li Xi nodded, turned around and waved his hand at Pang Yue, "Sister, I like you, can we still meet?" ”

I looked at Li Yuan, to be honest, Pang Yue really didn't know if I could see her or not.

Li Yuan looked down at Li Xi, who was holding his waist with one hand, and then looked up at Pang Yue, who was standing looking at him from a distance, "Yes, it will." After speaking, he smiled at Pang Yue and left with Li Xi.

After Li Xi left, Pang Yue walked in the courtyard for a while until Li Yuan appeared in front of her again.

"There's one last check tomorrow." Li Yuan said.

"Hmm!" Pang Yue replied lightly, she didn't care about these now, "Li Xi, she...... Are there really no ovaries? ”

Li Yuan's expression was a little ugly, and his yellowed voice revealed a trace of sadness, "Yes." ”

"Why is this happening?" Pang Yue said.

Li Yuan was silent for a while, and said in a low voice: "A major problem facing cloning technology is the low fertility rate of cloned animals, the more generations of reproduction, the lower the fertility rate, so far, the laboratory mouse breeding 6 generations, cattle breeding 2 generations have reached the limit, once the animal that provides the cells available for cloning dies, the genetic information will be cut off." ”

"That's why you're so concerned about my health, even my fertility?" Pang Yue said.

Li Yuan nodded, "Even now, when cultivating cloned mice, the egg cells with transplanted nuclei are immersed in a "histone deacetylase inhibitor" called "trichostatin A", although the fertility rate has increased, the fertility rate has only reached 15%. ”

"What do you mean......"
