Zongman: Plunder entry, starting master-slave contract

Lin Yuan traveled through the world, awakened the system, plundered entries, and became a hybrid of a brave man and a devil.
Many years later, he awakened his demonic bloodline, was driven out of the brave village, and wandered to the beautiful town of Juwang.
At the beginning, he killed Hyoudou Issei, plundered the Sekiryuutei's gauntlet, took in a capable sister, and obtained the master-slave contract magic.
Open the gate to travel through all worlds.
