Lu Li, a mentally retarded child, has been with the old tree for twenty-three years.
An operation gave him a new lease of life, but he only had a month's memory.
A small glowing sapling broke into his world.
"I am Dream Tree, the key to all worlds. I can take you to any world you want to go to."
"What are the conditions?" Lu Li asked.
"Jiechu..."
Just remember.
"On the 31st day, you must come back or you will be lost forever."
He accepted the challenge and embarked on a journey through time.
In the world of martial arts, he transformed into a peerless swordsman, lighting up nineteen states with one sword.
In the world of immortals, he cultivates immortality and asks questions, flies with a sword, and is free between heaven and earth.
In a science fiction world, he drives a starship, explores the universe, and searches for the meaning of life.
Every time he travels through time, he will gain a new identity and ability.
But every time he returns, he forgets everything.
Can he find his true self in reincarnation again and again?
Can he break the shackles of memory and become the master of all worlds?
