After studying for about half an hour, Su Yu had basically mastered the creation of plant-type lifeforms.
Since he had become proficient at creating plant-type lifeforms, it was time to create animal-type lifeforms next!
The method for creating animal-type lifeforms was similar to that for plant-type lifeforms: materials and spiritual energy were placed into the Eternal Spring—materials were reorganized and assembled—creation was complete.
However, animal-type lifeforms required one additional step compared to plant-type lifeforms: injecting a soul.
Plant-type lifeforms generally had no souls. Those that did were extremely rare, accounting for less than 1%.
Animal-type lifeforms, however, generally all had souls; the only difference was the size of those souls.
Su Yu had once seen this within the Soul Artifact, Kongwu.
If the Soul Space inside Kongwu were a boundless ocean, then Su Yu's soul, at the peak of Tier 8, was probably about the size of a blue whale.
A Tier 7 cultivator's soul was not small either, roughly the size of a seven- or eight-meter-long killer whale.
As one's strength declined, a lifeform's soul gradually became smaller as well.
For ordinary Tier 3 humans, the soul was only about the size of an ordinary ocean fish.
As for domestic or wild animals such as chickens, cattle, sheep, tigers, and deer, their souls were only about the size of shrimp or tadpoles.
All the souls were currently stored within Kongwu. If he wanted to create animals, he had to retrieve them.
"Everyone, get back to work!" Su Yu said to those present. "Next, I'm going into Kongwu to retrieve souls. It'll take quite a while. After all, I need to explain everything that happened earlier to the souls inside. I won't be out for at least a few hours."
"Alright, then. We'll get back to work."
"Let's continue clearing
