There's Something Wrong with This Magic Sword

Wei Wuqi traveled through the Demon Sword and obtained the system of becoming stronger while lying down. So... "Ding, you're awake. Demonic energy value +1." "Ding, the weather is very good today, the temperature has risen to 70°. It is suitable for climbing the tower. Please note that the first wave of cultivators is on the way." "Ding, you're not listening. Demonic energy value +2." … "The magic energy value exceeds 100, do you want to advance?" "Ding, I have advanced on my own according to the strongest magic sword advancement route." "Congratulations, the human-level primitive-level magic weapon has been promoted to the human-level transformation-level magic weapon. The complete skill point +1." "Do you want to use skill points?" "Ding, I have added some points according to the needs of the strongest magic sword." "Congratulations, you have obtained the skill: Breath of Death." … Thank you for the invitation. I am in another world. I am going to lie down and hide for now.
