Proof step 13 from proof rtc+-unfold-last (previous step)

p(c0, b), p(a, c), p*(c, c0), rtc(n0, c, b) ⊦ ∃ c. p*(a, c) ∧ p(c, b)

User applied rule exists right

And obtained the following new goals

Proof step 14:
p(a, c), p(c0, b), p*(c, c0), rtc(n0, c, b) ⊦ ∃ c. p*(a, c) ∧ p(c, b), p*(a, c0) ∧ p(c0, b)
