Liu Xin certainly knew why.
The Earth Elf's only attack ability is to control Demon Beasts, but when it controls them, it likes to deploy them all at once, without any human wisdom, not even keeping some in reserve for defense.
So when Xiao Zhan faced the Earth Elf, there wouldn't be a single Demon Beast around.
But why did Liu Xin lie to Xiao Zhan, telling him that the Earth Elf was protected by Demon Beasts?
The reason was that she wanted to take this opportunity to form a contract with Xiao Zhan.
Don't get it wrong, it was not about a Life and Death Contract, she just purely wanted to experience the feeling of forming a contract.
But she never expected that Xiao Zhan would make his decision so resolutely, making that decision which was even quite selfish.
This was beyond her expectation.
