How Come I Am Invincible Once I Collect Scraps?

Traveling to the fantasy world, Su Yuan became a useless handyman in the sect whose spiritual roots were broken and everyone could be bullied, and he lived with the rags. In despair, he awakens the [Invincible Repair System]! Everything can be repaired and nothing can be restored! Broken sword reborn? In the blink of an eye, the rusty scrap metal regained its luster, and the sword roared into the sky, but it contained a sky-splitting sword intention. However, it would shatter again with just one strike of the sword. Elixir residue? Refining it casually, the power of the medicine is condensed into a pill, which shines brightly and can help people break through the realm in an instant. However, the effect of the pill is only brilliant for a moment. The skill is incomplete? The complementary deduction points directly to the origin of the great avenue, and its power is earth-shattering. However, a practitioner can only operate it once in his life. He can even repair the corpse of a fallen strongman, allowing him to temporarily regain his peak combat power, but after one breath, he will completely turn into ashes. He can reshape broken spiritual roots and recreate peerless geniuses. However, the reshaped roots can only break through to a great realm once in his life. The ancient goddess carried half of the ancestral artifact and begged: "Please repair it, Master, and our tribe is willing to give half of the country!" The invincible Immortal Emperor came dragging his broken body: "Repair my body, and all the treasures of this emperor belong to you!" The ancient sect took out the fragment of the inherited jade: "If I can complete it, I will respect you as the eternal Taoist master!" Faced with the longing for immortals and Buddhas all over the world, Su Yuan sat in his shabby shop, playing with a magical weapon that had just been repaired but was destined to be brilliant only once. He smiled slightly: "Things can be repaired, and you pay the price." "But remember, the miracle I give you will only happen once."
