D-Class Healers Are Too Weak? so I'm Full-Time and Full-Time?

The global dungeon has arrived, and everyone can obtain a career. Lu Fan awakened as a D-class healer. At the beginning, he only had apprentice healing magic, and no one wanted to team up with him. So he started to play solo and accidentally entered a super long-term dungeon. Three years had passed since he started playing. At this time, Lu Fan has reached the full level of all professions, has over 100 million attributes, and has a backpack of various artifacts. Lu Fan thought that all dungeons were like this, but when he came out of the dungeon, he found that people's development was only one percent, or even one thousandth, of his? ! Asking people, they said that the fastest time to clear the dungeon is a few minutes, and the slowest time is about a week. This is totally wrong? When Lu Fan returned home, Xiao Qingmei came up to comfort him. It didn't matter that he had a different career. Don't be discouraged. Although he was three years late, everything was safe with her here to take care of him. The result is when downloading a copy. Chi Zhizhi: "Sorry, it's an undead skeleton. Lu Fan, please use healing to consume it, and we'll come back!" Lu Fan raised his hand and fired a healing spell. Critical hit-445362980! Chi Zhizhi: "???" At dinner time. Chi Zhizhi: "Lu Fan, I have learned cooking skills. I will make carrot soup for you to drink. It can restore your physical strength and increase your strength and mental power by 5%!" "Let me help you." Lu Fan helped cut a carrot and directly activated the cooking skill max+++. A bowl of carrot soup increased his magic power by 100 million, allowing Chi Zhizhi to kill the big BOSS with his bare hands and a fist! Chi Zhizhi finally couldn't help asking. "Lu Fan, tell me honestly, are you a monster?" Lu Fan stood still under the bright night sky, his hair caressed by the evening breeze and swaying in the air, and spoke lonely. "I'm just invincible."
