As for Black Spot and Green Claw, they have indeed been with him for quite a long time without any signs of evolution, which he found somewhat concerning earlier, though he realized it couldn't be forced.
Little Fierce arrived with them and has already evolved twice, while Little Six and Red Line have always acted with them and also evolved, so these two began to feel a bit anxious.
Sending them to face many enemies alone at the nitrate ore might have been seen by them as a special mission, hence they evolved.
"While that's true, I'm indeed quite happy they can evolve. Bai, you return to the shelter first and bring twenty Little Ice Lizards over for me, including Red Line."
"Gawu." Bai had just spent half the day outside the wall playing a hunting game with mutated creatures. Upon hearing Lin Yue's command, he immediately soared into the sky towards the main shelter.
