In 3035 AD, intern Ning Zian was involved in the "Holy Source Project" and was thrown into another world - the Forgotten Wasteland together with the divine tree species that could purify all things but also destroy everything.
Here is a cage of despair. Five hundred years ago, the "life-devouring gray fog" came from the west, devouring life and causing the collapse of civilization. The survivors are divided: the "fortress residents" who stick to the mobile fortress and move every ten years, and the "wanderers" who pursue the pure land of nothingness.
After five hundred years of struggle, the result was the ultimate bad news that the refugees brought back with their lives: at the end of the east, there was another source of life-devouring gray fog! Surrounded by gray mist from east to west, humanity's last refuge is being slowly crushed by death.
When the wasteland fell into the abyss of death, Ning Zian woke up. The devastating explosion implanted the out-of-control "Holy Source Tree Seed" deep into his body, turning it into the cold [Holy Source Tree System]:
`[High concentration of 'entropy destruction factor' (gray fog) detected... Fitness 99.9%... Activation started...]`
`[Novice mission: purify 10 units of gray fog...]`
`[Reward: Saint Origin Tree Seedling Growth +0.01%...]`
Swallowing the gray mist? Planting trees to survive? Ning Zian stared at the illusory seedlings in the field of vision that were eager to grow, and then looked at the dead gray mist that swallowed the world. A crazy thought was ignited in despair - this "Tree of Holy Origin" rooted in his life may be the only seed of hope in this dying world...!
