Spiritual energy?
Gu Tian was pleasantly surprised when he heard this.
The problem of his mental energy that had been troubling him was finally solved.
The upgrade of the undead base and the incubation of high-level troops required biological energy and spiritual energy.
Living energy could be obtained through the collection of resources by Ghost Servants.
As for the spiritual energy, it had been bothering Gu Tian because he did not know where to get it.
Now, the mystery was clearly solved.
By killing Magical Beasts and seizing their Magical Beast Essence Crystals, one could convert them into mental energy!
Gu Tian threw the Level 1 crystal into the energy pool of the undead base and successfully converted it into 5 points of spiritual energy.
Then, he returned to the Wind Wolf's corpse. Feng Lang's corpse had already been devoured by the Crawler.
Next to him lay the corpse of a ghost servant.
This Ghost Servant had just been killed by the Wind Wolf.
If it didn't die, he could bring it back to the undead base and let it drink the emerald green water of life in the energy pool to recover.
Unfortunately, this ghost servant was already dead.
Since he was already dead, there was naturally no value in his existence.
Its only value was to become nutrients for the evolution of the Crawlers. It could be devoured by the Crawlers and contribute to the evolution of the Crawlers.
Devouring the flesh and blood of one's own kind could also allow one to evolve.
After the undead soldiers died in battle, their corpses would become nutrients for their companions to evolve.
There would not be any wastage.
Undead soldiers that evolved by devouring flesh and blood were often quite terrifying. Their combat power far exceeded that of their own kind that did not devour flesh and blood.
He gained 5 points of spiritual energy and lost a ghost servant.
But it didn't matter.
Although they had lost one Ghost Servant, as twenty new Ghost Servants broke out of the ground under the gravestone and were supplemented by new members, the number of Ghost Servants had doubled!
It increased to thirty-one ghost servants.
The larger the scale of the Ghost Servants, the faster they could gather energy.
Towering trees fell one after another, constantly transforming into biological energy.
The thirty-one Ghost Servants collected resources very quickly.
In a short while, the creature energy storage of the undead base became abundant again.
Gu Tian had learned his lesson from the previous experience of being attacked by the Wind Wolf.
They couldn't just produce Ghost Servants. After all, Ghost Servants didn't have any combat power.
If they produced too many Ghost Servants and did not have enough Crawlers to protect them, they would easily be attacked by the Magical Beasts in the forest like before.
So...
"Biological Energy: 3124, Spiritual Energy: 5.”
Looking at the abundant bio-energy reserves in the base, Gu Tian gave the order without hesitation…
" Production of Crawlers, 100!"
