Even from Chen Heng's point of view, this Sword Tomb was still somewhat mysterious.
It was unknown who had set up this secret realm back then. There were large amounts of terrifying runes everywhere, densely covering every region, turning every region into an absolute land of death.
If a person walked into it, they would most likely die before they could do anything. Even with Chen Heng's current strength, it would be difficult for him to walk out in a piece.
Without a doubt, these were all very special places, and most of them had given birth to some unique existences.
Chen Heng called these places wastelands. The size and degree of danger in wastelands were different. Some of them took up a very large area, and the dangerous aura within them was particularly dense.
Some were the exact opposite. Not only did they take up a very small area, but the danger within them was not too great.
