Zhu Xian: the Sword of Gods and Demons at the Beginning, Nightshade Calls Me Brother Wang

Traveling through the world of Zhu Xian and binding to the system, the system mistakenly thought that he was in the world of Immortal Sword. Unblocking the sword of gods and demons, releasing Nightshade that has lived for thousands of years, and still being called Brother Wang by her? This system is so abstract. What Lu Chen didn't expect was that the system was far more abstract than he thought. After he broke off his engagement with Tian Linger since childhood. The system actually prompts: You and Tang Xuejian, the eldest lady of Tangjiabao, have terminated your engagement and will be rewarded with Shushan swordsmanship. People are killing immortals, but the system is killing immortals with swords? This script is messed up!
