701 Mysterious Heavenly Castle (1)

It was no wonder that the Mysterious Heavenly Palace was able to make a full retreat from the Boundless Mainland during those years. Their overall strength was indeed amazing.

As they advanced inwards, even if the speed of the two attendants leading the way were not that fast, it was still the speed of an individual with a Fifth Jewel cultivation base. The scenery on both sides constantly passed them as they advanced deeper for approximately an hour. By then, they were already in the mountains.

As they were walking, the terrain in front of them suddenly became steep as it turned into a slope that was almost 70 degrees. Fortunately, there was a flight of steps already dug into the mountain wall, so it made the climb slightly easier. Of course, the easiness only pertained to a Heavenly Jewel Master. If it were an ordinary person, the climb would still prove difficult even if they used both their hands and feet.
