Yang Xing perceived the rapid loss of spiritual energy within the Grotto Heaven; as the spiritual energy depleted to a certain extent, the concentration inside reached an extremely dangerous critical point.
Although he had never encountered such a decline in spiritual energy, he understood what would happen if the energy within the Grotto Heaven dropped significantly.
He quickly took out a vein-locking plate, within which was stored a spirit vein at the Peak Great Cultivator level.
This was the spirit vein of his original residence, kept as a backup, now becoming the hope of saving the Grotto Heaven.
But this only addressed the immediate crisis and did not solve the fundamental problem; the rate of spiritual energy decline within the Grotto Heaven was alleviated but had not stopped.
Now, with the support of an additional Peak Great Cultivator Spirit Vein, it was merely a temporary reprieve.
