To be honest, Shi Hao was also somewhat puzzled.
He had no particular relationship with Chen Ling, so why would she want to help him?
Though he didn't need any help, with the swiftness of Cloud Piercing Step, combined with the dimness of this underground chamber, he could make the Light Element work wonders, and escaping would not be difficult.
You see, these two had just revealed some secrets—Heavenly Demon Path, Corpse Ghost Path—they sounded terrifying, as if hiding some grand conspiracy.
So why hadn't Chen Ling silenced him?
Only Chen Ling herself knew that she saw Shi Hao as a reincarnation of the Demon Lord, so of course, she had to suck up to him.
The Demon Lord was currently unrecognized, and even Shi Hao hadn't awakened the Demon Lord's memories, so helping him now was like sending coal in a snowstorm, a stark difference from adding flowers to the brocade once his identity is announced later.
Perhaps she could even snag the position of a Demon Consort!
