Deep beneath the Thorny Pit, Cairo is looking for the faint source of sun energy that he is sensing. He did not even notice Sirius suddenly vanishing next to him as he was focusing. He could barely see down below the pit but he can summon a small light to illuminate the dark tunnel.
When Cairo lit up the place, he could see the fact that he was not even at the very bottom of the pit. He can even see the body of the Shadow of Apophis but he did not even bother attacking. He needs to prioritize finding the soul fragment of the Sun God Ra.
"Remember to not show that you have gained the Blessing of the Sun God Ra. I will also not use the skill that I received as we want to show the enemy that the Sun God Ra is not yet revived. The longer that the enemy does not know of this fact then the longer the Sun God Ra could recover his powers." Adrian stated earlier as a reminder to Cairo.
