The design of "hybrid engine" was that, when a trainer required the crystal suit or the Colossus to be fully outputted, his body tissues that stored the "reactors" would transmit the energy into the crystal reactor in the crystal suit first, which would be highly combined with the crystal fuel that the crystal suit carried itself through the complicated melting procedures in the crystal reactor before the spiritual energy was delivered to every power rune array and every battle unit on the crystal suit through the output tubes of the crystal reactor. Eventually, it would burst out in various forms of light blades, flames, or jetting force.
It meant that the two power sources at the beginning would coalesce into one.
It was not hard to imagine the difficulty of the task.
The spiritual energy outburst of a trainer was itself erratic, disordered, and hard to control even for the trainer himself.
