Lu Xi'an and Yao Wei stayed here for another seven days.
Blade, this kid, had already grasped various methods of obtaining food, and indeed it shouldn't have taken seven days. However, Lu Xi'an and Yao Wei needed more time to observe and confirm whether he had truly mastered this skill.
Lu Xi'an not only taught Blade how to find food, but also how to process it to make it easier to ingest and digest.
He even gave the kid a lighter, and also a small knife.
—— Blade said that when they were in Jiangnan County, they also had a small knife. But later, after being expelled from Jiangnan County, the knife was confiscated.
Lu Xi'an and Yao Wei had an extra small knife, so they gave one to Blade.
They also explained how to remain vigilant for danger nearby, and where to hide should danger arise, which they had to discuss with Blade.
Otherwise, if someone came and Blade was hiding in the very conspicuous escape pod, the outcome would only be an encounter with newcomers.
