This Warrior Wants to Become an Immortal

Lu An traveled through time. Then he discovered that in this world, there are cultivators, monsters, and ghosts. They can call the wind and rain, and they are extremely powerful. Mortals are like grass and they are precarious. What's even worse is that he has no spiritual roots. Fortunately, Lu An found himself carrying a deduction research platform. Just one rule: consume materials and deduce possibilities. Like that test stone [This deduction consumes half a test stone] [Deduction result 1: Grind it into powder and soak it in hot water to slowly temper your muscles and bones (success rate 100%)] [Deduction result two: test stone + hot bone grass, taken after medicinal bath, the effect may be doubled (success rate 50%, need to be verified)] [Can be deduced in depth (requires complete test stone)] Since then, a Saonian who carries a sword all year round appears in the world of immortality. Someone asked him: "You have no spiritual power, what's the use of holding a sword?" He thought for a moment, drew his sword and cut the hilltop on the opposite side. Then he said: "I don't know either, but I think it's quite useful." The man was speechless: "Aren't you just pure and powerful?" Lu An pouted: "What's wrong with Jinda? I haven't eaten your rice." The man asked again: "Do you really want to become an immortal?" "Think?" "Why?" Lu An held the sword, looked at the people flying in the sky, and said with envy: "Because he is handsome!"
