Among the three people who Zhao Fu knew, Wang Ergou and Guo Binglin was a part of that group. He had asked them to have a go, as Wang Ergou had a nimble mind and Guo Binglin was an attentive and thorough person. Eternal Night would not merely carry out assassinations. It would also do intelligence gathering as well, so it needed all sorts of people.
Zhao Fu had high hopes for Wang Ergou and Guo Binglin, so he asked them to try. Both of them had not disappointed Zhao Fu, and they had almost risked their lives to finally kill three Underworld Demons, obtaining the A grade Assassin profession.
They were both quite proud and joyful that they had killed three Underworld Demons, which were all incredibly powerful beings. Only those who had fought against the Underworld Demons would understand how terrifying they were.
