Lan Wangji & Wei Wuxian
The dragon that had slashed along his zhiji's leg is chased by dragons of its own kind, those dragons tearing it apart before heading back into the intial fray of things. There were a few more that he sends out, dragons that were encircling his husband. Dragons that would not like the fact that they trying to take out the one person that was his whole world.
This? It also was something that would put his own body through hell. Stress was not a good thing for his body and they both knew it. Just as they both knew he would push himself until his body couldn't take it and he was coughing up blood.
They would get through the dragons. Do their part and make sure that people stayed safe, even if it meant running himself into the ground to do it.
