Awakening the Hex System, Starting Right Away?

[Semi-invincible text] Shen Jiang traveled through time and entered a world full of ferocious beasts. Good news, Shen Jiang has awakened the Hex system. "System! Extract Hex!" "Ding, Hex was extracted..." "Hex extraction is successful: open the swing!" Shen Jiang: "System I&*'%'!" Ten years later... "Ding, Hex is completed. Congratulations to the host for getting the reward: S-level power!!!" The system is unblocked, and Shen Jiang, who has been failing for ten years, has officially begun his journey of cheating! "Ding! Congratulations to the host for getting the Prismatic Hex! Devil's contract! No training allowed! Improving your cultivation depends entirely on krypton life!" "Ding! Congratulations to the host for obtaining the S-level power: Feast! Devouring opponents across levels! You will receive a lifespan reward!" "Ding! Congratulations to the host for getting Prismatic..." Several two and a half years later—— Shen Jiang is a multi-faceted Hex, possessing several lowest S-level abilities! Billions of ferocious beasts are coming, the end of mankind! Shen Jiang stood on the ground, raised his hand, and the bloody flames burned away thousands of ferocious beasts. Take a good look! This is cheating! Note: The author didn't have an outline. I started writing as soon as I blinked my head. So in terms of settings, I listed them as I was writing. So there may be some things that you find strange or incomprehensible. It may be because there is no explanation about the settings in this aspect. You can try to read on... Of course, because of the limited writing style, some picky friends can't stand it. Please also use a gentler tone (ᵒ̴̶̷̤໐ᵒ̴̶̷̤). Love you...
