Someone please Explain this

I started re-reading because I went hiatus on this so I might have forgotten some parts and may not be accurate or mistaken so bear with me (and help from anyone to clarify me):

If you didn’t know or upset about the first scenario they did together: Wang Yi and Qin Xian are never siblings. The system made them that way because it’s a mission for Wang Yi to earn 80,000 points to reverse time before the incident happened and bring his friend back and later on we found his other friend, Bai Mo is also transmigrating to do the same but they working separately.

During the mission, Wang Yi became acquainted with Qin Xian and the more he transmigrates or do his missions, Qin Xian is always there, whether he has a different identity, it is still Qin Xian! The same soul from first mission.

It was later revealed that Wang Yi was originally a system, not a human called “Y” and Qin Xian was actually his host or the one doing the mission that current Wang Yi is doing (let’s call him OG Xian). Through Qin Xian, Y learned how it feels like to be human. This was when Qin Xian is in love with Y that’s why he taught and showed him human emotions are and this made Y yearned to be a human and be with Qin Xian. The cat you see always with Wang Yi was his successor whom he told when he was Y to create his own path and pretend he doesn’t know him if they ever meet again so that the cat won’t be punished by the master system.

Going back to the OG Xian, he also does his missions and completed it and as a reward, he asks for mind reading abilities.

Now this is when I have inaccurate info but I got the gist some parts: the master system eventually found out what Y wanted to do and intends to reset(?) destroy(?) or kill him(?) which shows Y dying on OG Xian’s arms.

There’s also an info about OG Xian’s soul shattering and becoming fragments and those fragments were actually the Qin Xians that Wang Yi have met throughout all his missions but of course have no memories of the OG Xian but little by little his memories starts returning

They said Qin's soul was breaking into 5 parts, which is... current's mission is the fifth... does it mean the ending is coming???? Noooooo I want more them roleplaying as another character but no sad end please

The current story they’re in is exactly what the OG Qin Xian life was and where he met Y so definitely were nearing towards the climax so yes, the last fragment of Qin’s soul, the soldier that has been finding ways to find Wang Yi
