Jiang Chen committed the specific effects of the two Legendary Traits to memory.
As for how to approach advancement...
The trait [Innate Machine Spirit], for the time being, he had no concrete ideas.
[Mecha-Pilot Fusion], however, could be explored appropriately in the direction of the "life virus" disaster that Master Chao was associated with.
"In any case, I need to advance first," he said.
Elevating to the 4th Rank and unlocking the permission for the second sublimation was the focus at this stage.
After all, a mecha's typical evolution involved merely absorbing modules, integrating power, and refreshing module slots.
Changes in other areas were not significant.
It was only during sublimation that the mecha would undergo drastic changes.
Codename, attributes, shape...
With the right combination, it was a breeze to elevate a mechanical construct's exoskeletal armor into a pure energy mecha!
