Without receiving a clear response, Lu Ping'an decided to return to his own turf.
He knew that it was not possible to get a response in the short term... Although the Saphire people had become fallen aristocrats, a rotten ship still has a few nails left.
But eventually, they would agree to Lu Ping'an's request and send a group to cultivate Mercury 42, just as with the Green Planet.
Of course, this was a personal request from Lu Ping'an, and the matter of leaving the country still required an application to the local government... Lu Ping'an estimated that they would complete all procedures with unprecedented speed, asking these 'masters' to leave the country.
The Ancient City was not resistant to the Saphire people, nor was it expelling them; they had become an inseparable part of the city (an important foreign investment project), but an excessive number of Saphire people clearly disrupted the city's balance.
