Destructive Phasing
Ves ended his call shortly after he promised to add this exceptionally powerful capability to the Dark Zephyr.
He did not make this promise lightly. He might not be a willpower cultivator, but he still valued his integrity as a mech designer. Ves wanted to make a serious commitment to Venerable Tusa in order to soothe the expert pilot's fears about subsequent delays and scrapping of features.
Managing relationships with high-value clients was part of a mech designer's job. Tusa had clearly been more badly affected by all of the delays than normal. Ves felt responsible for this, so he deliberately subjected himself to a hard deadline to ensure he went all-out into elevating the combat power of the Dark Zephyr.
Of course, the consequences of failure were extremely serious. An irreparable break would form in the relationship between Ves and Tusa. Ves would also have to bear the stain on his professional career for the rest of his life.
