After Demons and Eerie Phenomena Return, I Rebuild the Cultivation System

(Spiritual qi revival + an invincible protagonist from start to finish + a battle for supremacy among all races + a System and a mysterious old master + an expansive world, on the level of Perfect World)

Demons and strange creatures appeared one after another, the glory of the past had long since vanished, and the ancient cultivation systems of the myriad races had been lost. The human race, once the mightiest of all, had fallen into decline, and most common folk had become food for bloodthirsty creatures.

An ordinary transmigrator, Lin Ming, arrived in this desperate world. Demons ran rampant and strange phenomena revived. Fortunately, he had a System and a mysterious old master at his side to keep him company.

Step by step, he would grow stronger, rebuild the cultivation system, and once again bring the myriad races to heel. But just as he was about to reach the summit, he discovered that a world-shattering conspiracy had ensnared him.

What are the mysteries? Why did he transmigrate? Who is behind the System? Who is the living being standing at the end of the river of time? What is the curse that stretches across the rivers of time and fate? Why has humanity's ancestral court fallen into ruin? Where are those forbidden powers, and what are they plotting?

Do we still have a future?
