Locke had heard of Obelisk Stone Demons before. They were excellent large-scale defensive magical creatures. Once fully grown, they could create a defensive barrier that protected the Potion Masters within it.
Many Potion Masters liked raising an Obelisk Stone Demon precisely because of this ability.
It could provide them with a certain degree of protection while they were brewing potions.
Moreover, Obelisk Stone Demons could suppress the Magic Tide, as well as abnormalities in magical pressure and changes on the spiritual level, providing Potion Masters with stable brewing conditions.
An Obelisk Stone Demon that had carried a large amount of the Wizarding World's World Principle and absorbed a large amount of potion waste could even help Potion Masters create a secure environment in other worlds, especially those whose World Principle differed greatly from that of the Wizarding World, giving them stable conditions for brewing potions.
Locke happily placed the Obelisk Stone Demon into his Astral Ring. After thinking it over, he still agreed to enter the fourth round of the Heavenly Ladder.
Contrary to his guess, the fourth round of the Heavenly Ladder was not a Second-Ring-level potion test. It was still at the First-Ring level, but it was no longer as simple as providing a recipe for him to brew. Instead, it gave him requirements and asked him to combine a corresponding recipe.
Clearly, this was a new test from the Feathered Serpent Ancient Pavilion.
A Potion Master who could pass this entire set of tests would receive a tremendous boost in the field of Potions.
Therefore, he had no reason to stop.
After receiving Locke's affirmative answer, the Green Dragon Half-Dragon walked to the Light Transmission Device and sent a message. Soon, a reply came back from the device.
The Green Dragon Half-Dragon handed a card to Locke.
