A golden membrane with runes in the shape of a dove immediately coated his body like an added layer of skin.
The amulet he had just crashed was a top-tier monarch-grade artifact called the twilight fortress dove. It was a defensive artifact and was a one-time use defensive artifact with a timer.
For three minutes it would protect the user's body against any attacks at the level of a tenth stage palace realm cultivator. It only required the tiniest bit of qi to trigger it, a wisp would do. When triggered it would form a protective membrane on the user for three minutes, and when the three minutes were up whether there was an attack or not, it would shatter and disappear.
Lai Lei didn't choose to use it earlier even with the threat of the dagger because of that particular flaw. At the time he could still handle the lightning attacks being produced by the dagger, even though they paused a fatal threat to him if they managed to strike him.
