When there is a certain gap in martial strength, but the gap is not too wide, the role of wisdom becomes apparent.
Compared to Lin Yun, Dao Embryo's wisdom could only be considered that of a mortal.
He indeed had an exhaustive strategic approach, but not because of his intelligence, rather because he was overly powerful and knew he had only one weakness. To guard this single weakness wasn't difficult.
His calculations regarding the small world Lin Yun was in were also due to his control over fate, akin to being able to read the script in advance and make targeted arrangements.
In situations like the current one, that's where the difference in IQ shows.
Ordinary people know to find ways to deal with their weaknesses, while intelligent people will use their advantages as much as possible to create weaknesses for others.
The effects of Tai Bai's sword, as witnessed by Lin Yun, were strong, capable of taking him traveling through time. That sword from Tai Bai was very powerful.
