Objectively speaking, Wang Jiu is not an expert in biotechnology.
His greatest strength lies in Swordsmanship; in terms of knowledge about Swordsmanship, no one in the Myriad Realms can compare to him. In fact, one could argue that the Celestial Divine Sword itself is the embodiment of the true principles of Swordsmanship, leaving its authoritative status beyond question.
However, outside the realm of Swordsmanship, he holds no special privileges and is just an ordinary person.
For instance, despite possessing unmatched intelligence, his understanding of social affairs is sometimes even inferior to someone with a mild intellectual disability. In terms of Immortal Dao theory, Wang Jiu only learned some superficial knowledge after meeting the Jiu Immortal Venerables.
