The Alchemist and His Apprentice Cultivate Immortality in the Interstellar Era

The master of alchemy in the world of immortality was accidentally transported to a small planet that focused on the cultivation of physical and spiritual bodies. He accepted a little beggar with excellent spiritual roots as his disciple, and there was also a little sparrow with both "weapon" and "spirit" cultivation. When the boss experienced complex interstellar travel, interstellar wars, and witnessed extremely explosive man-made weapons, the boss said he was extremely satisfied! Accompanying the little apprentice to practice all the way, the growth path is exciting. They rely on each other and achieve each other's success. He is a master and disciple, but also a good friend.
