Let the child go after abortion, hoping that the child will be reborn as soon as possible.

After his release, he returned his merits to infant spirits, who had an abortion. You can do this:

I, xx (my name), would like to go back to infant spirits, where I had an abortion today, and wish them to put aside their resentment and die in the western paradise as soon as possible. Xx sincerely requests repentance.

But only if you really show repentance and swear not to rebuild, the unjust relatives and creditors will have his heart, and it will know whether you really repent or just pretend. Only repentance can resolve resentment, and they can go to a good place and stop pestering you.
