Lin Mu''s punch knocked up a lot of dust and debris, clouding their vision. But once it settled down, they could see the effect on the wall.


    "Huh… It could actually withstand it." Lin Mu was surprised.


    The wall now had a hole in it that was about half a meter deep and equally as wide. Fine cracks were also spreading from its edges and had ended after growing for about ten centimeters. While this looked decently big, one must know that Lin Mu''s fist was enough to punch through a meter thick sheet of solid steel.


    For a rock wall to limit the damage by this much was rather impressive, especially considering that there were no formation arrays reinforcing it. It was also not made of any precious material, but was just somemon rock. And yet it was able to withstand so much damage.


    ''Is this the limit of its depth?'' Lin Mu wondered and checked it again with his Immortal sense, but found it to be blocked again. "Hmm… it is definitely thicker." He realized and pulled his fist back again.


    ~BOOM~


    He threw another punch, deepening the hole by another fifty centimeters. "Still no change." Lin Mu noted. "Let''s see how much it can take and how far it really goes." He narrowed his eyes and started throwing punch after punch.


    ~BOOM~BOOM~BOOM~


    Hi fists turned into a blur as a flurry of fistsnded on the wall, expanding the hole in it. Content ? provided by N?velDrama.Org.


    Lady Kang on the other hand watched it from the back, feeling a bit amused seeing Lin Mu acting rather barbaric.


    ''To think the first thing he would do after entering the Inheritance ground is to test its durability…'' she thought to herself.


    Though this did make her wonder just how tough the wall really was. She didn''t have a reference for Lin Mu''s strength after all, and tested it out herself.


    She pointed a finger at the wall as its tip glowed.


    It was as if a tiny star had manifested on Lady Kang''s finger before she shot it at the wall. The star flew like a bullet and struck the wall, causing a hole to appear on it as well. But unlike Lin Mu''s it was much smaller.


    ''Huh… Barely twenty centimeters deep and ten centimeters wide… He can actually exert that much power without actually using any skills?'' Lady Kang couldn''t help but be surprised.


    She could easily tell that Lin Mu was just using his baseline strength and not even his body cultivation. And despite doing that he was able to exert greater strength than Lady Kang using one of her Qi skills.


    Of course the Qi skill she used was not that strong and was one of her basic ones, but that was still a skill. Even if she was a sixth Tribtion Stage Immortal, she didn''t think she would be able to exert raw power the same way as Lin Mu.


    ~huu~


    A strong breath from Lin Mu made Lady Kang look back, making her witness his handiwork. Now arge man sized hole was created in the wall. It was about four meters deep and one could walk into it. Rather than a hole, one could even call it a small tunnel now.


    "Looks like the walls are quite thick… Though it doesn''t seem like we are inside the ground. The walls are still the same stone bricks." Lin Mu determined.


    "Are you done with your test?" Lady Kang asked.


    "Yeah, with how tough the walls are, I don''t need to worry about this ce copsing under our attacks at least." Lin Mu replied. "Let''s see the rest of the area." He said before moving towards one of the directions.


    The room they were in was about a hundred meters wide and twice as long. It waspletely empty and it didn''t seem like there was anything present here.


    ~Humm~


    But just as Lin Mu and Lady Kang were about to move, a change happened.


    "What''s that?" Lin Mu narrowed his eyes, as his Immortal sense picked up on something. "The wall… it''s repairing itself." Lady Kang saw the hole filling up.


    Lin Mu observed it and found there to be no formation working there. It was as if the wall was a living object and ''healed'' the wound that Lin Mu had inflicted onto it.


    About thirty secondster, all the damage was healed and it was as if Lin Mu had never even touched the wall. Lady Kang checked the hole that she had made, and it had healed as well. "Merely half a minute to heal all that damage… The creator of this ce certainly kept durability in mind along with sustainability." Lin Mu muttered. This was amon thing for several Inheritance grounds that were meant to be used by several people over the years. When people entered these grounds, it was inevitable that they would end up inflicting some damage. The grounds might be fine for a few cycles of this process, but at a certain point the damage would be too much.


    This would cause the Inheritance ground to eventually be ineffective and lose its purpose.


    To prevent this, the Inheritance grounds would usually have self repairing arrays in addition to having high durability. But even then, the repairs would usually happen when the people had left the Inheritance grounds and it was in its sealed state.


    It would take this time to repair itself, and reach its original state to be ready for the next group of entrants.


    But this Inheritance ground seemed to be on another level, to be able to repair itself within a minute. "A Celestial''s treasure is certainly on another level." Lady Kang said having witnessed the process herself.


    "Indeed… We might have more surprises perhaps." Lin Mu replied, finally moving towards the end of the room. There a pair ofrge stone gates with no designs or carvings awaited them.


    Lady Kang and Lin Mu looked at the gate wondering if they were supposed to push this open.
