After Kai and the others had left, Su Lun didn't continue to stay at the original site of Central Prison Ruins.
According to Sereya's words, now that the "Heart of Isaac's Alchemy" was on him, the Fallen Angel could sense it and would come looking for him at any time. Only with Mr. Jing by his side could the danger be minimized.
He signaled to Mr. Jing and then headed in the opposite direction of the trio, searching for a relatively safe place in the depths of the ruins to wait.
It was a tower building that was still relatively sturdy.
Su Lun jumped in; the place had a broad view with all sides having broken windows that let in the breeze, allowing him to detect any incidents promptly.
But he had just stopped when a mysterious person whose face couldn't be seen appeared out of thin air. It was like a beam from a projector lit up, and then the person was there.
Seeing the iconic gold-patterned cloak, Su Lun knew it was someone from the Jing Organization.
