I Transmigrated to a Cultivation Continent with a Demon Armor from the Start

(The author is a beginner. This is my first time writing a story, so please forgive me if it's not very good.) (This book and the author's The Immortal Path on the Immortal and Demon Continent are linked. The titles may differ, but they take place on the same continent. That means this book's male and female leads will cross paths with the male and female leads of The Immortal Path on the Immortal and Demon Continent. Please read both books with an open mind: their protagonists are different. You can consider this book's male lead either the first or second male lead, and support whichever character you like. Also, the author is a student, and this is my first time writing, so please be understanding if you don't like it.) The female lead is Baili Shouyue. He's male at first, but the author will write him as a woman later on. The author likes BL and loves shipping the Kai-Yue pairing. All right, here's the actual synopsis: The protagonist, Mo Kaiyan, was originally from Blue Star. He was secretly a national-level scientist and the eldest young master of the Mo family. But after being betrayed by a former friend, he was hunted down and died in a car accident. After his death, he unexpectedly transmigrated to a cultivation continent and became bound to the Cultivation Demon Armor System. But his good fortune didn't last long. When Gu Yuanming accidentally angered the Heavenly Dao, it gathered the soul power of generations of Demon Body Realm sect masters and fought Gu Yuanming to a mutual defeat. Just as Gu Yuanming was about to die, Mo Kaiyan happened upon the scene and saved him. But Mo Kaiyan also used up all his energy and fell unconscious for three months. In the early and middle stages, Mo Kaiyan also meets his confidante, Baili Donghao, who becomes Baili Dongxue in the middle and later stages. The two eventually become cultivation partners, defeat the Lord of Darkness, and stand at the pinnacle of the world. (The final boss is A Ming Motian. That's a spoiler.) Little do they know that an even greater danger awaits them. (That, of course, is for the second book.) Now, let us follow protagonist Mo Kaiyan on his path to the summit.
