"He agreed to come so easily?" Lan Ruo stared at the man in blue in front of him, somewhat surprised.
The Lan Clan infiltrating this place and waiting for an opportunity to present itself and then sending an invitation was something that they could only resort to after losing their means of communication with the main family in the Upper Three Heavens. But Lan Ruo himself also admitted that there might have been some other less aggressive way of going about it.
For example, sending a message, using a flying sword to send a memo in secret, or sending an invitation card. These were all methods that people in the martial world or normal people would usually employ.
Inviting someone face-to-face like this was equivalent to telling the other party —'We know you're here and we know who you are, so you have no choice but to come!'
There was a threatening edge to it and aggression too, as well as making a show of their strength.
