The fireworks were made in advance.
However, the illusion pattern that was produced after the launch required Bobo's own whimsical ideas.
The images of the flying horse crossing the river and Rheagar smearing oil were all from Bobo's imagination.
Maintaining this kind of imagination itself consumed a lot of concentration.
Considering that Bobo had set off fireworks after drinking, Matthew deduced that she must have been extremely focused.
Other than focus.
She did show some artistic talent.
Hence, Bobo's previous evaluation of the Occult Machinists and Mages was not without reason.
Matthew partially agreed.
The main reason was that the mage community was too large. It was difficult to use a medium or average to represent the creativity of mages.
Perhaps the arcane machinists were naturally associated with art.
