The matters in the lab were settled.
In the remaining four days.
The elders treated Han Dong with the highest level of hospitality.
Firstly, they arranged for a clean human-compatible room in the castle, accompanied by three meticulously selected female crows to serve Han Dong's every need.
The so-called meticulous selection was also based on human standards.
The bodies of the three female crows were all considered perfect, only... they couldn't change their heads, which were still crow's heads.
In the end, Han Dong 'dismissed' these female crows and instead recruited Duo Zeya to assist him.
Every minute outside the city was extremely precious, and Han Dong planned to use this time to study crow magic.
Han Dong asked the crow elder to be his private tutor during these four days, learning a type of primitive black magic originated from the crow tribe.
As for the introductory magic book given by Lady Hera, he would slowly read it when he returned to the city.
