Full of guilt.
Shouldn't have been careless and not sent Lann Qiyue back in time, but instead brought her along, and especially shouldn't have left her here alone.
The main reason was that Lu Ye really didn't expect that in such a short time, the Blood Race would arrive.
Lann Qiyue deeply suffered from the Blood Race's poison. Under such circumstances, she had nowhere to escape and could only throw herself into the Blood River searching for Lu Ye's trace.
She probably didn't know the dangers of the Blood River, having seen little, so when she saw Lu Ye jump into the Blood River, she followed suit.
If she had known the Blood River's dangers, she would've waited for Lu Ye to come up and save her. In that case, no matter what, her life would have been secured.
Lann Qiyue was gone, and Lu Ye felt guilty, but there was another thing that made him feel even more distressed.
Zhang Julai was also gone...
