Waste Synthesis: Starting from Picking Up Garbage to Become Immortal

Song Tianming, useless, but not useless, just like useless.
He has the body of all immortals, the strongest physique of immortals, but he can only follow the immortal path.
At the same time, he was born in an era when the ancient immortals disappeared and the immortal path was broken.
There are brilliant martial arts, physical, divine, witch, magic, and magic here, but there is no immortal path, and you can't follow the immortal path.
There is always a way out.
Song Tianming accidentally got the Immortal Cauldron of All Things, and then started a happy immortal cultivation career of picking up garbage and combining treasures.
