My Cave Can Refresh the Buildings of All Worlds

[Xianxia Farming + Cave Infrastructure + Ten Thousand Realms Buildings + Steady Flow + Home Counterattack + Power Development] Lu Chen was framed by his fellow disciples and charged with stealing elixirs. He was sent to the Black Stone Valley where spiritual veins were exhausted and monsters were rampant, to guard an abandoned cave that no one wanted to go to. Everyone was waiting for him to die in the valley. Until he awakened the broken stele with his blood and became the palace master selected by the Taoist Foundation of the Ten Thousand Realms. A damaged barracks can summon the remnants of black armor; a withered spiritual field can turn the wasteland into a spiritual land; a damaged formation tower can use the mountains to trap and kill powerful enemies; a dilapidated alchemy room can replenish the remaining recipes and refining poisonous smoke... Whenever a crisis strikes, the cave may refresh a building from all realms. While others competed for spiritual veins, Lu Chen resurrected the depleted spiritual veins; while others sought opportunities, he turned every resource into spiritual fields, barracks, alchemy rooms, and cities; while others established sects, he wanted to run an abandoned cave that everyone despised into a Immortal Dynasty that suppresses all realms. But as the Black Stone Valley regains its vitality, the secrets of the sect's old contracts, the remnants of the Xuanjia army, and the destruction of the old court have also surfaced one after another. Facing more and more powerful enemies outside the valley, Lu Chen tightened his grip on the cave order. "Every brick and tile here is earned by me with my life." "If you want it, you'll have to pay for it with your life."
