第1章 亿万年修为，无敌了！

After billions of years of cultivation, he is invincible!

(You can use your invincible cultivation at any time, but your body needs to be upgraded! Don't suppress it, don't feel depressed.)
The good-for-nothing Chen Changan accidentally gained 999 billion years of invincible cultivation!
But because his body is too weak, using his invincible cultivation will deduct his lifespan???
So Chen Changan started a side business in the small clinic.
A medicinal herb that can extend your life by ten years can help you kill a demon lord.
A medicinal herb with a lifespan of twenty years can kill an Immortal Emperor.
A body-building technique that increases lifespan by fifty years, and a talisman that allows one to cultivate to the level of an Immortal Emperor.
……
A few years later, Chen Changan stood at the door of the small clinic. Looking at the creatures from all over the world kneeling in submission at the door, he sighed deeply.
If I say that I am just a small doctor who wants to cultivate my body and achieve immortality, would you believe me?

（修为无敌可以随时用，但肉体需要升级！不压，不憋屈。）
废柴陈长安，意外获得了999亿万年的无敌修为！
却因为肉身太弱，动用无敌修为就要扣除寿命？？？
于是陈长安在小医馆开起了副业。
一株增寿十年的药材，可以帮你干掉一个魔尊。
一株二十年寿命的药材，可以干掉一个仙帝。
一本增寿五十年的炼体功法，制作一个仙帝修为的护身符，
……
数年后陈长安站在小医馆的门口，看着门口跪地臣服的诸天万界生灵，他长叹一口气。
我如果说我只是一个想要自己炼体长生的小大夫，你们信吗？
