Ves grew satisfied with Harry's progress.
His innovation was not that big, but it not only increased the practicality of his tech, but also opened up a lot of new possibilities.
The possibility of making his own 'happy gun' that became more powerful when he grew more joyful had a lot of potential in his eyes.
As Ves continued to grin while he was anticipating all of the fun he could create with such a weapon, the other mech designer did not entirely look convinced.
"Sir…"
"What is it, Harry?"
"Are you certain you wish to base the Defiled Light Project on my E-ERC luminar crystals? There are other X-ERC that correspond to emotions that have proven to produce stronger effects. You should at least try out each of the prototype weapons for yourself in order to make a proper and informed choice."
In order to make sure he did his due diligence, he projected a list of X-ERC crystals and added a summary of their known strengths, weaknesses and other properties.
