After coming back to the training facility, Keith spent the afternoon absorbing blood-qi, then he returned to his living quarters. The duo Garion and Sen stayed by his side in the hopes that he would perform the technique.
But Keith didn't do it. He preferred to accumulate blood-qi for now and increase his warrior frame's level. The technique was fully copied and he just needed to wait till the system decoded the structure.
His main target was a unique warrior frame user with an ability to complement his technique so he could mix them up and perfect his own technique. Helping Garion improve will make others come to him as well.
With that, he could essentially study most of the warrior frames. If only one or two had something good, he would consider that a success. Compatibility with blood-qi techniques was a rare occurrence. The techniques had been passed down from their ancestor and over time, it adapted to a certain type.
