Come to think of it, it was perfectly normal. Sprout, the centipede, was something Javier Sinclair had refined from tens of thousands of venomous insects. He had kept it as a Spirit Companion afterward, and Sprout had followed him for several hundred years, so of course a bond had formed between master and servant.
For instance, back in the beginning, Javier Sinclair was just the leader of the Demon Cultivators in the Lower Realm and didn't even know he was the Demon God incarnate. At that time, Sprout had crawled onto his rear, yet the incredibly prideful Javier Sinclair hadn't even swatted it dead. This was proof enough that there was a special place in his heart for what he'd raised himself.
So it was perfectly normal for him to have left a safeguard for Sprout. After all, Javier Sinclair was fiercely protective of his own.
