Ye Chen was also stunned for the first time he saw animals with cultivation.
However, in the Great Thousand World, nothing is impossible; since humans can cultivate with the help of the heavens and earth, it's only natural that animals can do the same.
Most of these animals have probably accumulated a bit of Spiritual Qi in their bodies from eating the Spiritual Qi-enriched food that is abundant due to the island's unique environment.
Although the python and the three monkeys had Spiritual Qi within them, their cultivation was clearly not very advanced. Ye Chen faintly sensed their strength to be comparable to Ancient Martial Arts experts with Dark Energy, which showed that these animals still did not know how to utilize the Spiritual Qi in their bodies.
