The last page of the notebook turned out to be an introduction to the Life Spirits.
Life Spirits are Tier Five treasures, containing abundant Life Essence Qi, capable of replenishing the Life Force of exhausted Pet Beasts or humans.
It is one of the key components in synthesizing Tier Seven treasure, the Heart of Life.
Although this treasure is rated as Tier Five, due to its special nature and rarity, its value might be equivalent to Tier Six treasure.
After usage, Life Spirits enter the body of a Pet Beast or human, growing or perishing with them.
Before the death of the Pet Beast or human, removing the Life Spirits from their body would allow reuse.
Ye Bai felt a pang of anxiety, yet he calmly closed the notebook as if he hadn't seen the last page at all.
Ye Bai felt a sense of urgency; if someone discovered that Life Spirits were inside Big Gray, Big Gray would die.
Never underestimate the greed of human nature nor the desperation of those clinging to life.
