Shuangshu's Crazy Batch: the System's Way to Cultivation to Immortality and Counterattack

Modern best friends Su Wanwan and Gong Yaoyao both traveled through the world of immortality, but as soon as they opened their eyes, they encountered a massacre! When you are about to die, you will be bound to the "Crazy Batch Symbiosis System" - if you dare to deceive me about my inferior spiritual roots, I will use poison to make you unable to survive; if you dare to laugh at my mediocre qualifications, I will set up a killing array to destroy your soul! "Ding! The host's murderous intent value has been detected and exploded. Unlock the crazy batch mode!" Su Wanwan quenched poison on her fingertips, but there was a smile in her eyes: "I heard that you want my Chaos Spiritual Root? Then keep your life." Gong Yaoyao's formation flags were flying, and her sweet voice concealed a knife: "Sister said she wanted to chop you alive, how could I let you die happily?" They are the crazy twin stars who are feared in the world of cultivation, and they are also each other's only weakness. When the aloof immortal Mo Yuan breaks his precepts and becomes a demon for Su Wanwan, and the unruly demon lord Ye Liao crushes Ling Xiao for Gong Yaoyao, this counterattack is destined to be bloody - "You protect my soul from death, and I will give you a road paved with blood." But no one expected that the ultimate mission of this best friend's system would be to overthrow the entire world of immortality? !
