Perhaps the brutal methods of Xiao Tian Lang made other spiritual beasts somewhat dissatisfied. One of the sixth-order spiritual beasts let out a loud roar, and in the next moment, Xiao Tian Lang turned his head to look at it, his massive body pouncing over to knock it to the ground. His powerful claws, like two sharp blades, pierced into the abdomen of this spiritual beast, tearing it apart with a fierce swipe, blood splashing everywhere. Even a powerful sixth-order spiritual beast was no match for Xiao Tian Lang's single strike, crumbling like tofu under his attack.

  Then, the Howling Sky Wolf pressed its two claws on the body of this dying Ling Beast, raised its head and let out a long howl!

  Overbearing aura is fully revealed! This is the overbearing aura of the king of beasts!

  Consolidating one's rule with iron and blood, a method that may not work in the human world, but in the world of spiritual beasts, it is the strong who are revered, and those who do not submit will die.

  When Ao Tian Lang was dealing with this sixth-grade spiritual beast, Tang Feng had already turned around and ran towards the depths of the gorge.

  Behind him, those two crippled five-stage spirit beasts followed, limping and hobbling as they chased after him.

  Tang Feng didn't want to waste time entangling with those heavily injured spirit beasts. The longer he maintained the ability to borrow a corpse and return to his soul, the greater the burden on himself, and the more suffering he would endure. He had to hurry to the depths of the forest and then disperse this ability to meditate and recover from his injuries.

  Fortunately, the medicine he had just drunk was slowly taking effect in his abdomen, healing Tang Feng's injuries. Although it was very slow and not very effective, Tang Feng felt a little better anyway.

  The deeper you go into the canyon, the darker it gets. The interior of the canyon was originally dimly lit, and now it's even harder to see any light.

  However, a strange phenomenon occurred in the Tang Wind. The skeletons of the spiritual beasts began to gradually decrease. At the entrance of the canyon, the skeletons of the spiritual beasts were piled up like mountains, one on top of another, countless in number. But as they walked further inside, the density of the skeletons became thinner and thinner. After walking a few more miles deeper into the canyon, there were significantly fewer skeletons.

  However, beneath those skeletons, Tang Feng felt something that was emitting energy. These things emitting energy were unknown what they were, intersecting one by one inside the canyon, some fluctuating strongly, and some very weakly.

  Tang Feng originally didn't want to bother with these things, he now only wants to find a place to settle down. But as he walked, he wasn't careful and tripped, by the time Tang Feng got up again, his hand had grabbed something round and about the size of a pigeon egg.

  He picked it up out of curiosity after briefly touching it on the ground, because this thing was also emitting energy fluctuations.

  It's not a very strong fluctuation, it's a relatively small one.

  Before Tang Feng could carefully examine the object, his heart suddenly skipped a beat, and once again, he generated that energy that was particularly effective at suppressing yin souls.

  Not only that, but Tang Feng also seemed to hear a mournful howl from the things in his hand.

  A surge of energy sprouted from the spot where his heart was, and it extended along his palm into this thing. The eerie howling sound suddenly stopped, and then a moderate flow of energy flowed back through his arm to his dantian.

  The originally thin and weak Dan Tian Qi suddenly became more abundant.

  Can these things actually stir up the power of my own heart? Is there a dark soul in here too? Tang Feng was so excited that he didn't even notice the two spiritual beasts chasing behind him, and quickly bent down to search for these round pigeon eggs along the fluctuation he sensed.

  In a short while, Tang Feng found more than thirty of them. There were really too many, under each beast's skeleton, there was such a small pigeon egg, some were exposed in the air, and some were pressed by the beast's skeleton at the bottom, it took a lot of effort to get them out. They wouldn't emit any light, but they were still found accurately by Tang Feng.

  These pigeon eggs found by Tang Feng contain different amounts of energy, some more and some less. However, under the accumulation of sand into a pagoda, the aura in Tang Feng's dantian actually recovered a little, and his meridians were also filled with much more energy.

  He continued to move forward, searching for the pigeon eggs around him as he walked. His internal energy had been partially replenished, and the medicinal effects of those liquids were gradually taking hold, alleviating his exhaustion somewhat.

  Further ahead, the number of Ling Beast skeletons decreased significantly, but the energy contained in the pigeon eggs that could be found became increasingly enormous, to the point where Tang Feng found it hard to believe.

  Similarly the size of a pigeon egg, one can find in front, but the energy contained is more than a hundred times that of what was just found.

  The number of Ling Beast skeletons and those pigeon egg-sized things seemed to be in an inverse proportion, Tang Feng thought for a moment, and his mind became somewhat clear.

  These things should be the source of energy within the spiritual beast's body - the inner elixir!

  Ling Jue had told him before that when the spiritual beast reached the third stage, an inner elixir would appear in its body. The nature of the inner elixir was similar to a human's dantian, but for spiritual beasts, it was undoubtedly much more important. Their strength and weakness depended entirely on the amount of energy contained within the inner elixir.

  The inner elixir he found himself was clearly that of a third-grade spiritual beast, so the energy contained within was very little.

  What was found later should be the fourth and fifth order spiritual beasts, with energy far more powerful than that of the third order.

  The Beast Grave is a place where every spiritual beast wants to come before it dies, but not every spiritual beast can make it here. On their way here, they may be eaten by other beasts or die for other reasons and fail to arrive, yet many beasts still manage to walk in here and die.

  And here, there is also a very clear hierarchical division.

  The spiritual beasts that come here to die, the weak ones will choose to die outside, while the strong ones will walk inside, arranged in a stepped shape. So the further Tang Feng goes inside, the fewer spiritual beast corpses there are, and the stronger the inner elixirs he finds.

  The corpse of the dead spiritual beast rotted away, but a crystal of energy remained. Over the years, these inner elixirs that contained the spiritual beast's essence developed some variant consciousness, similar to a yin soul, which was suppressed by Tang Feng's Ling Xin.

  Of course, things can't be generalized, some spiritual beasts died too early, and they've been dead for decades or even hundreds of years, so their inner elixir energy is so weak, and many inner elixirs have completely lost their energy, becoming completely useless.

  This is just Tang Feng's own idea, but it should be about 80% true.

  Going further forward, Tang Feng even found the inner elixir of a sixth-grade spiritual beast. Counting along the way, he found at least over 1,000 inner elixirs. The third-grade ones were the most numerous, accounting for about half, with over 300 fourth-grade ones, around 100 fifth-grade ones, and less than 100 sixth-grade ones.

  After a long time of stopping and searching for the inner elixir, the two crippled spiritual beasts finally caught up from behind.

  Before Tang Feng could even make a move, the two of them had already fallen to the ground and stopped breathing.

  They were too badly injured, one had its front leg torn off by the howling wolf, and the other had its hind leg torn off. No matter how much mercy the howling wolf showed, it was impossible to achieve perfection. When they arrived in front of Tang Feng, they could no longer move due to excessive blood loss.

  It seems this place is relatively safe.

  If Howling Sky Wolf still wants to use his old tricks to deal with himself, those wounded spiritual beasts will not be able to support such a long journey.

  As he continued to move forward, Tang Feng suddenly found that there were no more spiritual beast bones in front of him. However, within his perception, a few extremely strong and overbearing energy fluctuations came from a distance of one mile away. These energy fluctuations were far stronger than any of the inner elixirs he had just searched for.

  With such stimulation, Tang Feng ran faster than anyone else, without caring about the severity of his current injuries.

  Always running to the source of the energy transmission, Tang Feng exerted his eyesight and looked over, only to see four massive skeletons lying here. Among these skeletons, one of them looked about the same size as Xiao Tian Lang's body. The remaining three were not inferior to the first one, it seemed that they were also spiritual beasts that dominated the entire Qu Ting Mountain before their death, just like Xiao Tian Lang.

  Is this the resting place of the king of beasts? This location is already considered to be deep within the beast's tomb, and although there is still a distance to the bottom, no energy fluctuations have been detected from that direction.

  Only the king of beasts has the qualifications to rest in this place, and only the king of beasts can walk to the front of the six-stage spiritual beast. Judging from the level division of the Beast Mausoleum, these four must be the kings of beasts without a doubt.

  Having walked all the way here, it should be completely safe now.

  Those divine beasts, even if they were dead, would definitely not come here to die, because except for the Howling Sky Wolf, the rest are not qualified. The Howling Sky Wolf itself will obviously not run into the beast tomb to wait for death in order to kill Tang Feng.

  In the passage at the front of the Beast Grave, some sounds of movement could still be heard, and it seemed that another unlucky spiritual beast had been injured by Xi Tian Lang and lost its way in.

  But Tang Feng wasn't worried about them; since they had already landed safely, the heart that Tang Feng had been holding up also relaxed.

  Found a relatively clean place, slowly sat down with his legs crossed, Tang Feng took a deep breath and dissipated the ability to borrow a corpse to return to his soul.

  In an instant, endless pain came from all directions, Tang Feng couldn't hold back his breath and gritted his teeth to let out a muffled roar.

  Although it was the same injury, he had just reached the middle stage of the Heavenly Rank, but now he had directly fallen to the top grade of the Yellow Rank. How could he bear it? Moreover, after using the Borrowed Corpse Return Soul ability, there would be a terrible price to pay, and Tang Feng hadn't fainted from the pain already showed his strong willpower.

  This pain lasted for a very long time, until Tang Feng felt numb all over his body and the pain gradually disappeared. The dantian and meridians that were originally stored had become empty and uncomfortable at this moment, and the small skull-like thing in his chest seemed to have withered a lot.
