Space-time Attribute, Void Oaths

In the laboratory, Su Bai walked up to Mewling Fox with a crystal clear bottle of black potion and said, "Come on, drink it."

"Hing?" Can I drink it with milk? Mewling Fox glanced at the black potion and asked.

"Of course."

Nodding, he took out a carton of milk and poured it into the potion.

Milk had a particularly low energy content and hardly reacted with the ingredients in the potion.

After mixing them, he poured the potion into a bowl and placed it in front of Mewling Fox.

In half a minute, it finished all the potions.

As the effect of the potion spread to its whole body, wisps of condensed black mist gradually appeared around the fox's body.

A black air vortex appeared from time to time at the center of its eyebrows.

"Go back inside the contract book and take a good rest," Su Bai caressed its head and said. This potion was made using the Dark Wolf Heart Fruit that he had just obtained.
