Since this is the final chapter I'm not going to put the spoiler button.
I love this manhua. They forgot to adapt some parts of the end but it is very nice. There is a part where they talk about children, Mosheli tells Qin that a long time ago he underwent a treatment to not have children because he does not want the G**-level DNA to continue. He tells Qin that if he wants to have children he accepts and supports him but Qin tells him that he understands the reason why he does not want children and that he does not want them either and that they will always have each other to love each other. Here it is implied that they do not adopt children either. If I remember correctly, the exact end of the novel is where Mosheli shows Qin the graves where they will be buried together when they die, and tells him that he has already written the epitaph too, Qin asks what it says but Mosheli does not want to tell him because according to him that is a writing that only other people should read, not them, they should only live their love. The End.
