Lin Yuchen nodded in understanding.
Guan Chibei's explanation seemed ordinary, but it was actually very reasonable. Firstly, it was hunting practice. Lethality required practice. Being able to go to the battlefield meant that one had guts in archery. Many noble sons had learned archery, but they lacked practical training. Even if they shot at the training grounds, they were specially prepared prey, so they lacked real killing intent and guts.
Secondly, Guan Chibei specially said that the person who 'taught him' had said that he hit the mark perfectly. This also showed that he was talented. As a noble, Lin Yuchen had seen such capable people in this world.
Guan Chibei had talent in archery, so it made sense that he had improved quickly by chance.
In terms of skills, talent had a very important role.
