"Leaving already? Don't you really want to take a look inside? The teacher really invited you," Richard said, seemingly reluctant, from behind Phil.
And this only hurried Phil's departure, "Next time, next time, please thank Master Guluo for his kindness on my behalf." As he spoke, Phil didn't look back and walked up to the surface and disappeared.
Richard stood in place for a long time, making sure Phil hadn't returned, and then he walked through the iron door and closed it tightly behind him.
All of this was a bluff aimed at Phil; he was betting that Phil wouldn't dare to actually come in. Sure enough, he was right, Phil really did not dare to enter.
And since he didn't dare come this time, he probably wouldn't dare next time, which meant Richard could ensure relative safety for a long time. Most importantly, he had, through Phil, successfully fabricated a non-existent person—Master Guluo's student.
