I, a Super God of Law, Signed a 300-year Contract with the Elf Race

Chris was reincarnated into a magical world and became a half-blood elf. However, due to his low standing, he was only tasked to guard the Stepwell of the Moon.
At this moment, Chris was assigned a system. [Ding! Congratulations for coming to the Stepwell of the Moon. The host is rewarded with <The Body of Nature>.]
[Ding! Congratulations for coming to the Adventurers’ Guild. The host is rewarded with <10 times cultivation and meditation speed>.]
[Ding! Congratulations for coming to the Tree of Elves. The host is rewarded with <unlimited forbidden curse>.]
[Ding! Congratulations for coming to the Spring of Life. The host is rewarded with <The Eyes of the God of Law>.] Chris quietly went to many places for 300 years.
He became a super god that was more superior than the God of Law.
Until one day, the armies of the undead attacked the Sacred Continent. Terrifying disasters descended. The vast Kingdom of Elves was about to be destroyed and all the living creatures on the Sacred Continent faced annihilation. Chris defeated the armies of the undead single-handedly!
