In the novel, XL's mortal realm is his tribulation and his sacrificing for his people will make him immortal and become LSS's brother 500years later, am I correct? This is why LSS did not allow TTJ to kill XL.
yup u are right. in the novel XL mortal realm was his tribulation.
I am sure why LSS not allow TTJ kill XL.
I think LSS still have some trauma of GYJW cos GYJW die on the hand of devil god 2.0 (ep 1),
So if she saw TTJ kill XL, it kinda trigger her past memory that Devil God was evil and unable to be change.
