Xiang Beifei kept trying, and after spending the whole morning, he finally managed to design the formation.
"Erha, come over, let's do an experiment."
"Woof woof!"
Xiaohei excitedly went to find Erha with a bow and arrow.
"Awoo awoo!"
Erha protested loudly, trying to escape, saying why not use the tribe's people or find two meat-winged monsters for the experiment.
"How can we experiment on the humans in the tribe? As for the meat-winged monsters, these two are too weak. Using them for the experiment would probably set the rune power for a month. You're so strong, contribute a little!"
"Awoooo!"
"Why aren't Xiaohei and I the test subjects? We're immune to bricks! Who told you not to have resistance to bricks?"
"Awooo!"
Erha cursed loudly.
"Heavenly Connection spiritual power crystal!"
...
In the end, Xiang Beifei bribed Erha with a piece of Heavenly Connection spiritual power crystal. Delightedly licking the crystal, Erha stuck its butt high up, facing them.
