There was no need to go into detail about the Stellar Train Crew's meeting with Ningguang.
With Lumine there, communication between the two sides went smoothly.
Partway through, Ganyu came to pass along a message: the adepti had received word from Yanfei, who was all the way over in Nod-Krai, confirming that the Stellar Train had helped the locals deal with the Abyssal disaster.
It was hardly surprising that Yanfei had a way to send emergency messages to Liyue over extremely long distances.
Liyue might not look especially advanced technologically, but appearances were deceiving.
As Teyvat's largest trading port, Liyue had always kept up with the times.
The locals simply didn't use much machinery because the people of Liyue had their own body-tempering methods.
A Millelith captain without a Vision could withstand a bomb powerful enough to blow apart a Fontaine clockwork meka, and come away with nothing worse than a few scrapes.
It was worth remembering that in ancient times, a fully armed Millelith squad formed into a battle formation could stand against gods and their followers.
Even in the modern era, when individual Millelith soldiers weren't as strong as the ancient Millelith squads, someone at the level of a captain could still take on a Xuanwen Beast one-on-one without much trouble.
With bodies that strong, Liyue's Millelith had little interest in firearms. The arrows they shot were more powerful than the muskets used by ordinary Fontaine guards.
Most of Liyue's technological sophistication was found in adeptal mechanisms.
Some of Cloud Retainer's inventions were rather ridiculous, but in Teyvat, who could say that the technology behind an automatic cooking device was primitive?
So it was hardly surprising that Yanfei, a junior among the adepti, had access to emergency-only methods of communication that worked much like long-distance voice transmission talismans.
