[System+Shuangwen+Sister Control+Single Female Protagonist+Second Personality] Su Chen traveled to the world of immortality. Both his parents died, and he only had an adopted sister to depend on him. By a coincidence, her younger sister Su Yao was spotted by an elder of the Lingxian Sect, the third force in the East Continent, and accepted as a disciple. She became the pride of the sect and a beauty who was madly pursued by many male disciples, but was rejected one by one. When Su Yao went home once, she was followed without knowing it. The following disciple saw the close relationship between Su Yao and Su Chen and thought that Su Yao fell in love with a mortal. From then on, the story spread from ten to ten, and eventually Su Chen was assassinated after Su Yao left Su Chen. When Su Chen died, the system accidentally awakened and became the second personality of his sister Su Yao... I don't know how many years later, Su Yao faced the siege of many demons. At the critical moment, she called out to her brother! The next second, Su Chen's consciousness came online. He looked at the many demon lords from years ago and gave an order! The law of heaven was stirred up, and thunder fell to kill all the demons!
