When Ethan narrated his fortuitous encounter to Merrick, he not only told about his increased cultivation, but he also told about the Cultivation Techniques, basic knowledge about the Spirit Plants, which were the Welcome Gift from the Gentle Voice.
Thus, Merrick believed Ethan was able to complete the task of the Secret Realm with the help of those gifts along with his Cultivation Talent related to Spirit Plants.
When Merrick convinced his Second Brother Edwin, he mentioned all these things and even added a few things, exaggerating Ethan's talent in the Spirit Plants.
Therefore, Edwin Lin has come up with a task for Ethan which is related to Spirit Plants.
"I will complete the task and won't disappoint the Family Head."
On the other hand, Ethan was happy because he was confident in completing the task.
He knew that becoming an Elder of the Lin Family was not easy as there would be others questioning his abilities.
