"Reincarnated into the World of Magic as a demon, the last thing Davis expected was to grow up right amidst the arms of angels. Ever since the group of philanthropic angels took pity on his miserable birth and adopted him, Davis has been forced to keep his evil identity a secret while he signed in to the system. 
""Ding! The Host has signed in at Angel's Pond, 'The Saint's Halo' is rewarded!"" 
""Ding! Devil's blood activated. Sign in error. 'The Devil's Curse' is additionally rewarded!"" 
""Ding! The Host has signed in at God's Throne, 'Gold's Holy Axe' is rewarded!"" 
""Ding! Devil's blood activated. Sign in error. 'The Devil's Manifistation' is additionally rewarded!"" 
After a thousand years of quietly signing into places in the City of Angels and being rewarded with double the rewards, Davis's true identity finally came to light! Now as a true Devil, Davis had both the world of angels and demons surrendering at his feet!"

Only the ancient Dragon Race with a strong bloodline could make Lilia willingly acknowledge it as her master.

Whether Lilia was forced or willing, it did not matter.

What was important was that Lilia successfully connected with the ancient Dragon Race.

This was what the Dragon Queen Sarafini cared about the most.

She had asked Lilia to bring Toru to Paradise Island to communicate and she had allowed Lilia to take the opportunity to get close to Davis. Her goal was to contact the ancient Dragon Race on Davis and revive the declining Dragon Race.

Since she had contacted him by recognizing him as her master, Lilia should not be in danger for the time being.

Moreover, that ancient Dragon Race did not have any ill intentions toward the current Dragon Race.

Sarafini instantly had a guess in her heart which was the ancient Dragon Race hidden in Davis' body was actually forced to hide in Davis' body for some reason.
