2. " The Original Creator of Secrets " Author: Wood Stone Ice Heart. Category: Fantasy, Mysterious Fantasy. Completed. You can enjoy it without worry.

The following is a brief introduction of these novels:

1. " From Skeleton Soldiers to the Undead King."
On the first day of transmigration, when I escaped Border Town, people called me a weak and pitiful skeleton monster.
After leveling for three years, I roamed the Undead Mountains. People called me the Undead Knight under the moonlight.
After leveling for ten years, I dominated the underground maze. People called me the Skeleton King on the throne.
After leveling for 30 years, I broke through the Demon Abyss. People called me the Angel of Death!

2. The Original Creator of Mysteries
Hong Wen had transmigrated to the world of the Lord of the Mysteries and seemed to have become the new Primordial One. However, all of this was far from as simple as it seemed. The plan that spanned several eras would eventually end in this era, and the Creator would begin to awaken.

These works all have good reputations for your reference.
