My Simulated Longevity

How difficult is the immortal way!
What's more, this world of cultivating immortals has been completely changed by a plague!
Ordinary people are infected with disease, and once immortals come into contact with them, their cultivation base will decline at least, and they will return to heaven in severe cases, so the immortals will be separated forever;

Li Fan came across, although he was ambitious, but he could only wallow in the mortal world, wasting his life.
Fortunately, at the end of his life, he finally awakened a strange treasure, which can turn the truth into a falsehood, turn the real life into a dream, and return to the time when he just crossed over!
Thus, Li Fan began his long journey of life!
In the second life, Li Fan finally ruled the world for fifty years, but he searched the world and found no trace of the fairy. Only at the end of life can you see the traces of immortals.
In the third life, Li Fan devoted all his energy and planning, but in the end he was no match for the immortal's sword!
Fourth world...
...
I, Li Fan, am a mortal, I will never regret for a lifetime, but I only want to live forever!
