If it weren't for the sudden appearance of the howling wolf, if it weren't for the pursuit of those hundreds of spiritual beasts, he might not have ended up in such a predicament. These spiritual beasts forced Tang Feng to maintain his Borrowed Corpse Return Soul for an extended period, exhausting his physical potential, and now that his abilities had dissipated, backlash was inevitable.

  Several ribs were broken at the chest, which was slapped by a claw of Xi Tian Lang. There were no external injuries elsewhere on the body, but many muscles were torn apart, and the Qi in the Dantian and meridians was completely emptied, making it unbearable for anyone.

  The Ling Beast's inner dan that Tang Feng had just found were all thrown into the Shadow Space, but at this moment he didn't plan to use these things to recover his Qi. Using the energy stored in the inner dan to recover one's Qi was indeed a very convenient method, and Tang Feng had done so before. However, back then it was for escaping, for maintaining the ability to borrow a corpse to revive, which was different from now. Now that he was completely safe, Tang Feng had to rely on his own efforts to fill up the meridians and dan Tian in his body, only this way would not affect his future cultivation. Relying on external objects multiple times was ultimately not the right path! Although Tang Feng was young, he thought more thoroughly than anyone else.

  Slowly exhaling a breath, trying to relax the mind and body, the trembling and spasms caused by pain in various parts of the body slowly subsided after a long time.

  Tang Feng attempted to sense the flow of spiritual energy around him, but he didn't feel anything. However, he knew that the spiritual energy was omnipresent in the world, it's just that his current strength wasn't enough to perceive its flow.

  Borrowing the power of the bloodless boundary, Tang Feng had once stood at the peak of the Tianjie's high rank, personally experiencing the powerful feeling of possessing Tianjie strength. Now, he naturally has some understanding. Sometimes, only when one stands at that height can they see the scenery they should see. From this perspective, although Tang Feng's use of Borrowing Corpse Returning Soul brought him some trouble, it also brought him considerable benefits. At least, his mental state is much more mature than others of the same rank, because he knows what kind of strength a Tianjie master should possess and what they can do. Others don't have this advantage. As he activated the Unusual Technique, Tang Feng gradually entered a state of mind like still water, imagining the surging aura circulating in his meridians.

  There is no hint of internal energy in the body, this time it's like the first time I practiced, but a thousand times more difficult than the first time.

  In the fantasy, the unpredictable tactics had been circulating for an unknown number of cycles, and a energy slowly grew out from Tang Feng's dantian, while the external spiritual energy also began to surge into his body.

  With this tiny, almost negligible amount of energy as a starting point, Tang Feng set them in motion, following the third layer of the Wú Cháng Jué's cultivation route, and with each cycle, these energies would grow several times larger. Gradually, the gentle streams merged into mighty rivers, and the rivers converged into the Yangtze, thriving ceaselessly.

  The originally withered skull had also recovered at this moment, and it echoed with Tang Feng from afar, spitting out spiritual energy.

  The withered dantian and meridians were once again filled with a wonderful feeling of being filled with Qi. This feeling made people linger, making them joyful. Tang Feng was transforming the unpredictable trick while dissolving the medicinal properties of the medicine he had drunk.

  Although it has been such a long time, those medicinal liquids were all refined from precious herbs, how could they be easily dissolved? They were only absorbed by Tang Feng for a very small part, and the vast majority of them are still in Tang Feng's body without moving.

  The medicinal energy is stirred up and transformed into the meridians, following the circulation of the heavenly cycle, delivering the medicinal energy to every part of the body. Under the observation of the heart's spirit, these dissolved medicinal energies present a kind of hazy glow, permeating one's muscles, wrapping around those damaged areas, slowly repairing them.

  This is a great but slow project, because Tang Feng only condensed those medicinal liquids and didn't refine any wound-healing pellets, so the effects of these medicinal liquids are somewhat reduced. If Mo Liu Su were here, she should be able to refine these precious materials and make them fully utilized. Even so, Tang Feng also feels much better, and his damaged muscles are gradually being repaired.

  Tang Feng's muscles and internal organs had become much more solid since the last time he was tempered, allowing him to take on a mid-grade Yellow-stage opponent relying solely on his physical strength. However, this body that made him proud among cultivators of the same level couldn't withstand the rampage of a high-grade Heaven-stage expert's aura.

  The gap is really too big, and the storage volume and quality of aura between the two are completely different.

  However, at this moment, Tang Feng was somewhat surprised to find that the energy he obtained through cultivation was actually more concentrated than before, which means that the quality was much better.

  When the energy flows through the meridians, it is even more rapid than before. Tang Feng even feels that there is an uncontrollable swelling sensation in his dantian, as if something inside is bursting to emerge.

  Could it be that he himself was going to advance to the Mystic Stage? Tang Feng couldn't help but think of this possibility.

  To be honest, since practicing the Uncanny Method, Tang Feng didn't really expect his own promotion in this world's ranking system. What he expected was the promotion of the Uncanny Method. Only the promotion of the Uncanny Method could bring him earth-shattering changes.

  However, the ranking system of this world also provided some reference for Tang Feng. He was promoted to the second layer of Wu Chang Jue at the sixth rank of Lianyun, and then promoted to the third layer in the middle of Huangjie. If he continued to calculate like this, his promotion to the fourth layer of Wu Chang Jue would likely require at least Xuanjie upper rank or even Dijie lower rank, because the further back he went, the more difficult his promotion became.

  But one mouthful won't make a fat man, everything must be done slowly, from Huang to Xuan, it's just a small step up.

  It's been about two months since I broke through to the third layer of the Unstable Formula, and now I'm wearing the Indestructible Armor. During my cultivation, I can gather spiritual energy more efficiently than before. Plus, with the life-and-death battles against Xi Tian Lang and those spirit beasts, both my body and mind have been pushed to their limits, making it not impossible for me to break through again.

  Thinking of this, Tang Feng felt a bit more at ease.

  He was really afraid that his own promotion would lead to trouble in the future, and he wouldn't do something that would ruin his foundation just for a moment of pleasure.

  He cast aside the distractions in his mind and immersed his spirit into his dantian, wholeheartedly initiating the unpredictable incantation.

  Until this moment, he suddenly appeared, and the two strands of spiritual soul that were still in his dantian. The two strands of spiritual soul, one gentle and one cold, intertwined with each other, constantly twisting and turning, sometimes entwining and then separating, producing a dazzling seven-colored light within the dantian, illuminating the entire dantian with a brilliant glow.

  Tang Feng couldn't help but let out a bitter laugh, his master was fighting for his life outside, while she was safely inside her dantian, unaffected by the wind or rain, only enjoying the fruits of victory.

  But who makes oneself her master? Who also makes oneself drool with an insatiable desire.

  It didn't even get damaged after being chopped by Siniang's Flame Blade for half a day, and it also saved its own life from the claws of Xi Tian Lang. Just this kind of invincible defensive power is enough to make people fight over it.

  Having an unbreakable armor is equivalent to having an additional wall of solid gold. Although it's indeed small, only covering the front and back chest, this is already sufficient. The back and front chest are precisely the fatal positions that enemies often target, so in the future, with the unbreakable armor, Tang Feng can at least increase his survival chances by a considerable margin.

  The armor has the effect of assisting in self-cultivation, and when worn during cultivation, it can also help gather the spiritual energy of heaven and earth. This is a good thing that even the Hundred Spirit Dan given by Bai Xiaochun cannot compare to.

  The Hundred Spirit Pill still needs to be refined, requires gathering medicinal materials, and has a time limit, only being effective within the next twelve double hours after consumption. In contrast, the Unblemished Armor doesn't have these drawbacks, as one can simply wear it while cultivating.

  So, Tang Feng is now miserable, but the price he paid is well worth it. Not only did he help Ling Xue collect one of the four divine souls, but he also got a great deal in the Beast Grave, those internal elixirs are each filled with a lot of energy, many of which have enormous energy reserves, especially the last four, they are equivalent to the peak of the Heavenly Realm, although they died many years ago, their internal elixirs haven't changed at all.

  Now thinking about it, my decision at the time was quite unjustifiable. If Tang Feng had known that he would be facing a terrifying King of Beasts, he would have obediently returned to Tianxiu to cultivate for a few more years before coming back to Qu Ting Mountain to look for trouble.

  Since Jingqing has already done it, regret is useless. It can only be used as a lesson for the future. Everyone makes mistakes when growing up, and the key is how to treat them. The so-called "past experience serving as a teacher for the future" is precisely this principle.

  The mysterious trick is still in operation, and the swelling sensation in the dantian is becoming more and more obvious. Even the small skull is trembling slightly.

  At that moment, when the swelling sensation reached a limit, Tang Feng suddenly felt his whole body light and extremely comfortable. The aura flowing in his meridians surged to another level, even its quality underwent some transformation.

  He let out a gentle breath, and Tang Feng's heart was as calm as an ancient well.

  Is this the Xuanjie stage? I feel that I have indeed become much stronger than before, whether it's my perception, spiritual power, or the explosive force of the Qi in my body, all of which have increased by a level.

  It seems like this, should be breaking through the yellow stage upper rank, and got promoted to the mysterious stage.

  Tang Feng had been cultivating since he started, and during the Lian Gang period, his progress was quite rapid. However, at that time, his strength was relatively low, so even if he advanced, there wasn't much change. But from Lian Gang 8th rank onwards, he suddenly jumped to Huang Jie upper rank. At that time, he was still tempering his physical body and didn't have any perception of it. This time, however, it was very obvious, especially at the moment of advancement, as if he was standing on cloud nine, feeling light and airy like in a dream.
