Under Jia Yan's supervision, Black Bear did not hold back much.
The knowledge he imparted was, at least from the point of view of the Earth people, extremely precious, so perhaps, the Earthling apprentices emerging from here could have a promising future.
Jia Yan himself was indifferent to these things. Although he could grasp them at a glance, he could not possibly go to Outer Stars alone, learn such technical knowledge one by one, and then teach it to Earth people one by one, right? He might spend his entire life teaching without having enough time.
After all, relying on craft like this is not something that one or two individuals can solve. Even if one reaches Galaxy Level, they wouldn't ordinarily specialize as technicians unless their mind is out of sorts.
So Jia Yan would at most lend a helping hand, offering these Earth children the best learning environment. Perhaps they would truly become the pillars of the future.
As for himself, he leisurely passed several days.
