After a Hundred Years of Upgrading, I Became a Giant Demon Lord

Lin Mo, who traveled through the world of cultivating immortals, became a low-level member of the Blood Demon Sect, trapped in a bloody arena where lives were at stake, and the loser would become a source of training for others. On the verge of death, the immortal upgrade device suddenly awakens. All skills, spells, elixirs, and magic weapons can be upgraded with one click, and their quality will increase step by step. The first-level Blood Evil Arrow can instantly advance to the second-level Blood Spirit Cone. Healing and strengthening his foundation by devouring essence and blood, his cultivation has steadily improved. The ants that were slaughtered by others in the past have now shown their fangs. Be forbearing step by step, facing the suspicion and prying eyes of the Foundation Establishment Protector, using your upgraded abilities to accumulate information and breakthrough realms, while dealing with the treacherous struggles of the organization. I don't want to fight with blood, but in this world of immortality, the weak prey on the strong, and murderous intent comes one after another. Forced to take action again and again, in life-and-death fights, Lin Mo, who possesses the power to upgrade beyond the heavens, finally loses his ordinary nature in the endless disputes. He doesn't want to do evil, but he is forced to kill decisively; he has no intention of becoming a devil, but the whole world regards him as an evil old devil. Let's watch the young man with the power of unlimited upgrades rise against the sky in the dark world, break free from the shackles of fate, and finally step to the top of the devil's path, dominate the world, unstoppable!
