In My Rebirth, I Can See the Source Code of Heaven

Lin Xuan traveled through the world of immortality, and at the beginning he was in the alchemy furnace of the great elder of the Demon Sect, and was about to be boiled into a "blood spirit pill". Fortunately, he had a companion system "Zero" bound to him. However, this golden finger is a bit tricky. It can neither create artifacts out of thin air nor kill bosses instantly. Its main authority is [Deduction of Heavenly Law]. "Since you can't activate Wushuang, then just be a quiet bastard in this Demon Sect." Seeing the loopholes in immortal cultivation techniques and restrictions all over the world, Lin Xuan, who was a senior programmer at a large factory in his previous life, made up his mind to survive among the corpses in the mass grave.
