I recommend " Sign In for a Hundred Years, From Sword Immortal to Unleashing the World." The novel's main character, Qin Yun, transmigrated to the Shu Mountain world and became a Shu Mountain disciple. He was punished to guard the Demon Sealing Pagoda for a hundred years before awakening the sign-in system. Every time he signed in, he would obtain powerful powers. The protagonist used the method of signing in to become stronger, and was known as the invincible sign-in. If you like Qidian novels, this book is definitely not to be missed. I hope you will like this novel.
