Zhao Cheng was on a journey towards north to battle the barbarians, while Song Jia was having an inner battle of her own.
It was not physical injuries that kept her asleep, nor was it because she didn't want to see Zhao Cheng's face as he had suspected. Rather, it was because the original host of this body, Li Jia, wanted to come back.
There were several theories about transmigration in the 23rd century. It was a very obscure science to research, thus they have not produced any concrete evidence and conclusion up until now. As for how one person could transmigrate while the other couldn't, they thought it was because of the energy of the soul.
Just recently before Song Jia accepted her first job, there was a man who was close to dying that had been sealed by scientists inside an airtight chamber. It was actually the second experiment of its kind, the former having been dismissed due to inevitable errors.
The airtight chamber was made from the most advanced technology, not letting even a single nano-particle escape or come in. They measured the accurate mass and energy of the dying man while he was sealed in and then measured again his mass and energy shortly after his death. To their pleasant surprise, there was a negligible difference in his mass and energy.
It was not proven yet, but the scientists thought that it must be the 'soul' which escaped its physical constraints and thus caused the difference between the two measurements. As for how transmigrators could occupy the body of another person, they theorized that it was simply because their soul's energy was greater than soul of the former host.
There were also special circumstances in which a transmigrator with a weak soul could occupy another body, but that was when the original host was on the verge of death or had completely passed away. In that case, since the body was an empty vessel, these transmigrators could occupy the body without any resistance.
Song Jia's soul was only a little bit stronger than Li Jia, so for her body to be riddled by injuries now, Li Jia took the chance to 'awaken' and battle it out with Song Jia for territorial rights.
"Who are you? Why are you inside my body?"
The battle was not fought by their human forms but by shapeless blobs of energy that made a 'ping ping pang pang' sound as they collided against each other. Li Jia howled accusations at Song Jia as the two tried to seamlessly merge with the sleeping body below them.
"I'll give it back to you as soon as I'm done," Song Jia tried to appease her. "Right now, I'm also trying to help you have a good life!"
"Good life? Good life? As long as that bastard is alive, how can I have a good life?!"
Li Jia redoubled her efforts, her rage fuelling her adrenaline. Song Jia blocked her attempts with all of her strength, feeling that if she had a body right now, her forehead would definitely be soaked with sweat.
"Zhao Cheng is the only monarch that could lead this world to prosperity, don't you understand? If he doesn't ascend the throne, this world would gradually descend into destruction. I can't let you kill him!"
"Future monarch or not, I have to kill him! Otherwise, this blood debt inside my heart, how would it be resolved? Leave the future to the future, let them take care of their problems! I have to kill that bastard!"
Song Jia tried to form a hand from her shapeless form and slap Li Jia. This kind of 'it's not my problem, why should I care' mindset was really making her feel irritated to death. Just before, she was feeling sympathy for this woman, but right now all of her good feelings had vanished into thin air.
This kind of spoiled and selfish woman who only looked out for her own sake, it was really a miracle that Zhao Cheng waited for her to don on the phoenix robes before deposing.
"Zhao Cheng loves Bai Mei Lien, what is wrong with that?" Song Jia placed her own bitterness and her own hurt ego to the back of her mind. "It was you who wanted to marry him, it was you who chose this kind of road! Before you married, did you ask him if he had anyone else inside his heart? Before you decided to recklessly love him, did you ever consider, if he would be able to love you back?"
"Being jealous of Bai Mei Lien is natural, but choosing to kill her, choosing to harm her, didn't you think about how Zhao Cheng felt? He abandoned you, yes, he didn't pay attention to you, yes, all those accusations inside your heart are true. But in the same way that you love him, he loves someone else too! Can't you understand?"
Song Jia was mainly dissatisfied with Zhao Cheng because he kept breaking his promises to her. But as for the fact that he loved Bai Mei Lien, Song Jia didn't have any problems with it. Bai Mei Lien was a nice girl, and she loved Zhao Cheng too. If this was a TV drama, she would be his love interest, and Zhao Cheng was the main character.
Li Jia unreasonably forcing her love on him and not caring if his own love got destroyed in the process, wasn't this the dark path of the villainess?
Since she occupied her body, naturally, Song Jia wished for the original host to be well and live happily ever after. If she couldn't become the love interest, then why not become a supporting female lead? Song Jia would match her with Wen Heng Zhi, the man Li Jia had a brief attraction with in her previous life. After she and Zhao Cheng got divorced, she would then make sure that Li Jia would have someone to take care of her for the rest of her life.
