The Inside of the Pyramid!

Lin An could only obtain the treasure in the largest pyramid if he followed an exact series of steps. 

If the steps were wrong, he would naturally be stuck in a quagmire in the Sacred Dragon Mystic Realm.

Among the sequence of pyramids, only the first, second, third, twenty-first, forty-third, and fifty-fifth pyramids harbored the treasure keys.

The other pyramids were just smokescreens. There would be no value in exploring them.

Lin An already had one of the Sacred Dragon Mystic Realm's key fragments in his hands.

He now understood that it was a spoil of war that had been obtained by the cultivators who had explored the Sacred Dragon Mystic Realm in the past. 

According to the basic rules of the Sacred Dragon Mystic Realm, Lin An knew that it would remain open for one month. Since he had the success rate system, he had a high chance of obtaining all the valuable inheritances in the mystic realm.
