It was generally used to store formation media, accumulate formation Mo, design formation diagrams, and serve as a place for Formation Masters to research, rest, and paint formations.
At this time, the main door was tightly closed with a lock, and it seemed there was no one inside.
Moreover, there were no monster cultivators guarding outside.
It seemed just like the Demon Refining Diagram, this formation stone palace was also a ’Forbidden Land’ for monster cultivators.
"Should I go inside and have a look?"
Mo Hua felt a stirring in his heart.
He released his Divine Sense, sensing slightly inside, detecting no presence of living people or monster cultivators inside.
It should be safe.
But it was hard to say, as cultivators’ perception occasionally could not be relied upon either...
Mo Hua thought for a moment and then took out a Copper Coin, using Heavenly Secret Calculation for a divination.
This time, the divination lacked the previously felt clarity of understanding cause and effect, sensing the heavenly secret.
He did not see the vast grand scene of all cause and effect merging into a heavenly secret, flowing as if a river through the heavens and earth.
There was only a slight touch of cause and effect.
The movement was very minimal.
Perhaps the ’novice benefits’ were gone; for future calculations, it would depend on his own understanding of the heavenly secret.
But this was also good.
Always making such a big commotion, he wasn’t too comfortable himself either.
The Copper Coin turned in the air, landing on the palm.
It was heads.
That meant there was no danger inside.
Mo Hua couldn’t help but look forward, "This Heavenly Secret Calculation is really useful. If I truly achieve insight into the heavenly secret, controlling cause and effect, avoiding misfortune and seeking fortune like my master, how powerful that would be..."
He put away the Copper Coin and approached the main gate of the Stone Palace.
The main door had a massive beast-shaped lock, engraved with a Four Symbols canine-tooth Pattern.
Sword Bone said: "This is a special formation lock within the Valley of Ten Thousand Demons. With this formation lock sealing the main gate, you can’t go in, it’s better to find another..."
But before it could finish, Mo Hua had already started to push the door.
The main door opened effortlessly.
Sword Bone was taken aback, and upon closer inspection, it found that the formation on the lock had been completely unlocked.
