With the White Tiger Kurenai (1) [R18]

After that, Kurenai continued teaching Aster about Qi—mostly through classroom lessons rather than practical ones. If they used the "shortcut" method, Aster would end up gaining too much Qi for his own good.

Such a case could lead to Qi Deviation—and most likely result in death shortly afterward.

But with his astronomical amount of Qi, the resulting Qi Deviation would probably drag the entire village down with him. As such, for her safety, Aster's safety, and everyone else's, she had to hammer all the theories and control techniques into him.

Thankfully, the control techniques came naturally to Aster. They didn't even need the entire day before Aster mastered all the Qi control techniques that Kurenai knew.

"It's already dusk. Let's end the training here," she said, clapping her hands together.
