Secret: I Can Upgrade Everything

After traveling through time and becoming a sacrifice, Lin Yuan awakened the power to "upgrade all things" in the crazy world of immortal cultivation. Mortal weapons can be upgraded to magic weapons, techniques can be optimized, and elixirs can be improved in purity - but every time they are used, the cost of eroding sanity is accumulating. At 17% erosion level, whispers continued in the ears; at 20% danger threshold, the illusion began to distort. The shadow believers are hunting for his "abnormal eyes". Jingxintang requires 10 low-grade spiritual stones for purification, and he doesn't have much time left. The left hand is the supreme power, which can fight against pollution and optimize all things; the right hand is the fatal price, and every upgrade brings you closer to madness. The ancient gods are watching, the way of heaven is a deception, and ascension is destruction. In this world where reason is more precious than strength, Lin Yuan must stay awake on the edge of madness - but this in itself is the greatest madness.
