"You mean, if I want to unlock the new function of the War God System, I need to accept the call of the Bramble Birds?" Gu Qing Shan asked.
[Correct] the System answered.
"That's great" Gu Qing Shan smiled, "not only will I get treasures from helping the Bramble Birds, I'll also become stronger, it's a win-win"
[Incorrect] the System replied.
"What is?"
[Bramble Birds are an extraordinary mystical creature, the worlds and items precious enough to be kept by it are also extraordinary]
[When such precious worlds run into any problems, the Bramble Bird would always choose to deal with it alone before anything else]
[If it doesn't do that and instead call for outside help, then some sort of unimaginable danger must be involved in that world]
Gu Qing Shan nodded.
That certainly makes sense.
