Traveling Through the World of Immortality, but It's an Ancient Era

[Growth + group portraits + opening up the realm of immortality + time travel + no system + discipleship flow] Due to a car accident, a modern young man traveled to the "Xuanhuang World", a world of immortality in ancient times. What greeted him at this time was not Long Aotian's luck and various beauties, but a survival dilemma that could be called hell. The human race is enslaved by the demon clan as a "living food bank" and used as "experimental consumables" by the demon clan. Even the human race in the cultivation system can only reach the peak of Qi training. But the gears of fate turned because of his arrival. Starting from the first resistance, with the help of his friends, he rebuilt his will from collapse, determined to open up a new era and a new world for the human race, and once again presented the scene where the human race was respected in the novels about cultivating immortals in his previous life. This trip... No regrets! He had many partners on this road, and also lost many partners. From struggling to survive at the beginning to saving the human race from fire and water, this was a desperate era! It is also an era full of brilliance of humanity! "Everything is for the human race, even if my soul is shattered and my body and mind are shattered, I will not regret it!"
