The level of internal energy has increased, and when using them to explode, the force and degree will also increase, so the power of using hidden weapons will also increase.

  Cultivation is just a path, a slow climb to the peak! In this world, what can truly eliminate enemies is one's own hidden weapons. And one's real strength is the driving force behind their hidden weapons.

  This promotion can be said to have been a long time coming, lasting around two months, the longest in Tang Feng's history.

  After the breakthrough, Tang Feng still didn't stop the rotation of Wu Chang Jue. As soon as he broke through, it was like adding another floor to a building, and naturally, he had to stabilize his current realm first.

  While cultivating the unpredictable trick, he let the medicinal properties dissolve in his body. When hungry, he would find some wild fruits or cooked meat from the charming shadow space to eat. Fortunately, Tang Feng had prepared many living supplies this time when he came to Qu Ting Mountain, otherwise, being blocked in the beast tomb really didn't have anything to eat or drink.

  In the depths of this beast tomb, there was hardly any light at all, it could almost be said that it was pitch black. If Tang Feng's eyesight wasn't relatively good, he would have really gone blind. The canyon was also unknown in depth, with vines entwining above, and standing here one could only see a faint outline.

  In the first few days, the howling of those spiritual beasts outside the Beast Grave had almost never stopped. Especially the wailing of the Xi Tian Lang, but gradually, these howls became less frequent, until they completely disappeared.

  Those spiritual beasts should have lost patience waiting outside, they can't possibly guard the beast tomb day and night, although they are spiritual beasts, they also have their own things to do, such as hunting, competing for territory, fighting for a mate, etc., how can they always stay outside, just don't know if the Ao Tian Lang has left or not.

  Tang Feng's injuries had mostly healed, the torn muscles had been repaired, and the broken bones in his chest had also mended. His physical strength had recovered to its peak state. It was just that being unable to see any light for such a long time made him feel slightly annoyed.

  Moreover, Tang Feng didn't dare to leave the Beast Grave for now. He was somewhat intimidated by that howling wolf. What if it was still guarding the entrance and he walked right into its trap?

  Tang Feng wanted to wait until Ling Jue woke up before leaving, as she had an exceptionally keen sense of the spiritual beast's presence. With her there, he could avoid the beast and safely leave Qu Ting Mountain.

  However, looking at the spiritual energy's appearance, it doesn't seem to have changed much from the beginning. The two strands of spiritual energy are still entwined, and the degree of fusion seems to be less than half. At this rate, who knows how long it will take for me to succeed?

  Staying in this place, there's nothing else to do except cultivate, even thinking about lying down on the ground and counting stars has become a luxury.

  One day is cultivation, two days are also cultivation. Except for sleeping time, every moment is spent cultivating, and Tang Feng feels a bit dull even with his good temper.

  If it were somewhere else, Tang Feng might still be fine, but here, where the hand can't see five fingers, it's as if he's being locked in a cage, making him inexplicably feel a sense of rejection.

  By now, Tang Feng couldn't calm down and cultivate this repulsive idea together, it's just like having a demon in his heart. If he didn't find a way to vent, forcing himself to cultivate not only wouldn't yield much results, but might also make him anxious.

  So Tang Feng wisely gave up on practicing the unpredictable technique, sat down on the ground and thought for a moment, thinking of finding something to do for himself. He stretched out his hand and opened his own Charm Shadow Space, and Tang Feng leaned in to take a peek inside.

  Yes, the space is very large and there are many treasures.

  Heavenly soldiers, soft sword of the fierce soldier, a large pile of hidden flying darts and other defensive mechanisms specially made to deal with Ye Chenqiu last time, as well as pots, bowls, ladles, rice, oil, salt...

  Tang Feng was taking a closer look at his own Charm Shadow Space for the first time, and for a moment, he couldn't take his eyes off it. Now, if someone gave him something shiny, he would treasure it as a precious gem.

  Looking aside, in a corner of the space, there was a pile of round and rolling inner elixirs, with unevenly stored energy inside.

  Seeing these inner elixirs, Tang Feng's eyes lit up! An idea involuntarily flashed through his mind that although he was not cultivating now, he could still use the energy of these inner elixirs to temper his physical body again.

  After the first tempering of his physical body, Tang Feng felt the benefits brought by the improvement of his physical quality. If it weren't for that one-time foundation, he wouldn't have recovered so easily from the injuries he sustained after borrowing Bian Wuxue's power.

  With his current physical body, he was indeed unable to withstand the energy rampage of a Tianjiao expert for an extended period. What if he were to temper himself further? What if he were to make his physical body even stronger through tempering? There must be a certain degree where he could withstand it.

  Since my current body can't withstand the energy of a Tianjie expert for a long time, I'll find a way to make it bearable! Borrowing a corpse to revive one's soul is a killer move that will still be useful before I become strong enough. This time was just good luck, being able to run to the Beast Grave to avoid the Ling Beast's pursuit, but next time won't be so lucky. A powerful Yan person will be like a fish on the chopping board after my killer move's energy is exhausted, waiting to be slaughtered!

  As long as his body can withstand the rampage of a Tianjiao expert's energy, Tang Feng dares to guarantee that the backlash from using his trump card will be reduced to a minimal extent.

  Thinking of this, Tang Feng's whole body was invigorated. He swept away the anxiety and irritability from before and took out a pile of inner elixirs from the Charm Shadow Space.

  Each of the inner elixirs was equivalent to a yin soul. Those four powerful inner elixirs, Tang Feng hadn't dared to use them because he didn't know if the spiritual beasts' inner elixirs had any other uses, so he just left them there and didn't touch them.

  With the inner elixir in hand, there was no need to circulate and condense the yin soul's technique. In an instant, all the energy inside the inner elixir was absorbed into the body.

  

  In just a moment, Tang Feng absorbed the energy of over a hundred inner elixirs.

  The meridians and dantian all have a slightly swollen feeling, Tang Feng suppressing these energies, not letting them be absorbed by himself. The outer body 'again like that time', the luoqi uncontrollably stirred up, rolling up a gentle breeze on the ground.

  It's still not enough! Tang Feng's meridian endurance is quite strong, and since he wants to temper his body for the second time, the more energy he needs, the better.

  With a deep breath, he absorbed over two hundred more inner pellets. Tang Feng nodded slightly and muttered to himself: "It should be about right." The meridians were now transmitting a slight pain, although it was still possible to absorb more, but Tang Feng decided to slow down.

  Take a deep breath, prepare to endure endless suffering, Tang Feng activated the unpredictable technique, and the energy in his meridians and dantian was fiercely pushed out in all directions, advancing into every corner of his physical body, seeping into the five organs and six viscera.

  This process was much more arduous than the last time. Last time, Tang Feng cultivated while tempering his physical body, but this time, he had to give up cultivating and only tempered his physical body.

  After all, he had just broken through to the Xuan stage. If he allowed these energies to settle in his dantian, it would only cause his cultivation level to rise further. Therefore, Tang Feng had to work hard not to let any of the energy settle in his dantian and instead drive them into his body.

  Physical refinement is limitless.

  A massive energy as soon as it enters the body, will wrap up every tiny part of the body, and temper it severely.

  Although it still hurts, Tang Feng feels much better than the first time. The suffering he has experienced during this period is too much, which also makes his endurance stronger and stronger.

  As the energy that had been compressed into various parts of the body was slowly digested and reduced by the flesh, the pain also gradually subsided, and the surging aura outside the body also calmed down a lot.

  Also don't know how long it took, Tang Feng felt that the energy he absorbed had all been taken in by various parts of his body. After checking the situation at his dantian...

  Tang Feng was very satisfied for a while.

  These energies are flowing in the meridians after all, and they also need to go through the dantian. Naturally, a part of them will be absorbed by the dantian. However, under one's full force driving, the energy absorbed by the dantian is very little, almost negligible. In other words, 99% of the energy absorbed this time was used to temper the flesh.

  After a brief rest of half a day, he casually made some food to recover his strength. Tang Feng took out two hundred inner elixirs from the Charm Shadow Space and absorbed them all. He then entered the process of refining his physical body again.

  A few days passed, and the inner elixirs that Tang Feng had found were almost gone, leaving only four powerful ones, a few sixth-grade ones, and more than 20 fifth-grade ones. The rest had all become useless.

  These past few days, Tang Feng had tempered his physical body five times, and had already refined the quality of his physical body to an unimaginable degree. This was completely a self-mutilating method, yet it brought him enormous improvements.

  He stood up and reached out to the side wall of the nearby canyon, Tang Feng stretched out his hand to explore, feeling that what he touched should be stone, and it was a relatively hard stone.

  Tang Feng concentrated his spirit and calmed his energy, standing in front of the side wall. He suddenly swung out a fist, directly pounding towards the side wall.

  "Boom!" A loud noise, debris flying everywhere, Tang Feng's body didn't move an inch, his entire fist was buried in the stone, all the way to his wrist, Book Network Hand-to-Hand Combat Group gave him strength.

  Not only that, but the sound of the fist wind breaking through the air was like a cloud-piercing arrow, making a sharp whistling sound.

  This punch, Tang Feng did not use his internal energy, but still relied on his speed and strength.

  He slowly withdrew his fist from the side wall, and with a sufficient gaze, he saw that the side wall had already been smashed out of a hole, with clear cracks visible all around.

  He clenched his fist tightly, but Tang Feng didn't feel any pain, and his entire hand wasn't even slightly injured, not even a scratch on the skin.

  He took out a flying knife from the Shadow Space and threw it in the direction of the Beast Grave's exit with great force. In the dark beast grave, a spark suddenly flashed after friction, and in the blink of an eye, it flew out for dozens of meters before being blocked by something, making a crisp "ding" sound.
