The Kingdom's scholars once went to the Alien Machinery City to study, and the professionals from the Alien Machinery City also came to the Kingdom for reincarnation. The two countries regarded each other from afar, taking what they needed, thus maintaining the minimum level of communication, which had been peaceful for many years.
