Yu Tong: This girl was from one of the enemy sects. When MC and young members of the allied sects were on a training expeditions, the enemy sects sent their disciples, including Yu Tong, to go and killed them. MC and Yu Tong fought a couple of times and tried to kill each other multiple times. While it might appear as if Yu Tong is evil, it is clearly stated that the enemy sects are there for revenge because the allied sects had previously messed with one of their projects. I personally see this as two groups on different sides, and not necessarily good vs evil. After the expedition Yu Tong is obsessed with killing MC, cause he made her feel inferior and groped her during their previous encounters. Later on, both group of sects are forced to work together against outside forces, during which time their relationship starts to change slowly. In my opinion it doesn't look like MC intentionally let her escape in any of their battles, but rather they were closely matched, and is not like he only forgave her, all the sects united and forgave each other, considering that non of the people she personally killed were legit friends of the MC I don't see why she gets singled out in other reviews. I find their relationship interesting, though it has taken a back seat and hasn't been mentioned in a long time.

Dong Li: This one is a bit more controversial and more questionable. She too was an enemy of the MC who tried to use and kill him, her personality is very selfish and she seems to only care about herself. When MC first joined her group he noticed right away that she was up to no good. After she killed all the other members of the group the MC tricked her, groped her (sounds familiar?), and set her up so a strong cultivator would kill her, unfortunately said cultivator was in her pocket. After that, MC ran around destroying her plans, killing her people, and leaving mocking messages. She felt humiliated and spent all efforts trying to kill him until eventually they were both forced to retreat. Later on, MC befriends her brother, who has great character. She laters tries to use MC again by forcing him to go on an expedition with her and help her get treasures by threatening his family, with no intention to actually harm them, but with every intention to manipulate the MC. The MC is not happy about this, but her brother tells him that his family is in no danger and that she is just bluffing, he also tells him that he can refuse to go on the expedition, but that he might benefit from it if he goes, and asks him as a favor to look out for his troublesome sister if he goes. With time their relationship changes, they save each other's lives, and come to understand each other better. The way they met is abnormal and I can understand why people find it hard to accept the romance flag, specially since this is the only one currently officially dating the MC. Some things to keep in mind are that Dong Li was doing her original killings as part of a mission from her clan, not sure why she was sent on that sort of mission, or if the killing was a core part of it, or just her way of accomplishing it. Worth noting too is that MC knew she was trouble from the start and chose to join and remain in her group, he also knew the others in the group were being set up to die by her and he chose to let them die, not quite the same as killing them, but MC is no saint. Regardless, she clearly only cares about herself and those close to her, and has no problem killing everyone else, MC wasn't close to her at the beginning, but he is now, and since he became close she has fiercely defended him. I like this relationship because it is different, I also like that the MC is aware of how abnormal it is, and is embarrassed when others point out she tried to kill him. In my opinion he has forgiven and in some case befriended people who have come much closer to actually killing him for the sake of a greater goal so I'm not bothered by it.
