I Am Full of Merit, Why Do You Want to Kill Me?

After traveling through time for many years, I worked hard to join the first-class sect Tianxing Sect, but due to my mediocre qualifications, I ended up living on the side of the road, chopping wood and fetching water all day long, and no one cared about me. When I was frustrated, I suddenly awakened [Positive Energy Cultivation System]! You can obtain "merit points" by completing tasks, which has endless magical uses. Becoming an immortal is no longer far away! I was ecstatic until I saw the mission details: [Do one good deed a day] - Steal the spirit-gathering pill used by senior brother to break through, and help him understand the principle of not relying on external things, the merit value is +100; [Helpful] - Write a love letter to the second senior brother in the name of the third senior sister to help the lover get married, with a merit value of +50; [Respect the Teacher and the Doctrine] - At the sect meeting, when the leader is speaking, dance vigorously to liven up the atmosphere and gain +200 merit points; [Unity and Friendship] - Go to the mountain behind Yunlai Peak and secretly protect the junior sister taking a bath to prevent thieves from peeking. Merit value +50; [Knowing the book and being a gift] - On the ninety-ninth birthday of King Bo Yang, he presented a copybook with the message "Longevity", with a merit value of +200. ……… As the reward for killing my dog kept rising, I fell into deep thought: Does this system have any misunderstanding of "positive energy"?
