Sonic Weapon (3)

That was precisely why the Ye Clan could not do anything to Zhao Yarou now. After all, she had unconditionally released all those people, and at the very least, she had not harmed them.

What everyone feared most now was Zhao Yarou's secret weapon. From the accounts of the people who had returned, that weapon seemed impossible to guard against.
