Song Shi came to an immortal world where demons and monsters were rampant. He thought he was going to take a trepidatious road to immortality, but ended up awakening to a death-defying system, gaining strength from death and getting stronger every time he died.

The whole style took a sudden change. Other people cultivated to seek immortality, but he was already immortal, and could only seek immortality by having himself killed in various ways, either by killing himself or by letting people kill him.

“You were killed 10 times by the Yin spirit, awakening the spiritual root of fire!”

“You were killed 10 times by the zombie, awakening the innate divine power!”

“You were killed 10 times for excess cultivation, awakening the Daoist heart!”

“You were killed by a formation, formation level +1!”

“You were killed by an alchemy explosion, +1 alchemy level!”

Pure Yang Spiritual Body, Nine Yang Divine Body, Sun Sacred Body; Vajra Spiritual Body, Golden Divine Body, Draconic Sacred Body; Psychic Sword Body, Innate Dao Body; Formation Master, Alchemy Master...

His cultivation was a fun journey, and he kept finding ways to kill himself on his way to the top of the immortal path...

Years later, the world rumor had it that once Song Shi died, the immortals were terrified, the demons trembled, and ten thousand Buddhas retreated!
