When a friend achieves something you could never reach in your entire life, people have two reactions: the first is indifference, you neither envy nor yearn for it, treating it as distant news unrelated to you, and continue living peacefully;
The second is excitement/jealousy/longing, whether emotions are positive or negative, you no longer want to continue your past peaceful life, but want to climb upwards, to get closer to your friend!
Lois was the first kind before, but after she summoned the Technique Spirit, she gradually leaned towards the second kind. From a pampered young lady who only 'knew a little' about swimming and hadn't even killed a Lala Fat, to now daring to fight with the Fish-Slicing Dragon in the sea, it shows how tempering the Void Realm exploration is.
This is the charm of the Void Realm.
