Stepping from the Yellow Rank to the Xuan Rank, even though it is only a lower grade of the Xuan Rank, the improvement is also quite huge. The level of energy in the body has come up, and when you use them to explode, the strength and speed will also follow, so that the power of using the hidden weapon will also increase.

Cultivation is just a way, a way to slowly climb to the highest peak! In this world, what Tang Feng can really destroy the enemy is his own secret weapon. And one strength is the driving force to support one's own secret weapon.

This promotion can be said to be a matter of course, lasting about two months, which is the longest promotion in Tang Feng's history.

After the breakthrough, Tang Feng still did not stop the operation of impermanence, he had just broken through, just like a building with an additional floor, he naturally had to stabilize the current realm.

While cultivating the trick of impermanence, he let the medicinal power dissolve in the body, and when he was hungry, he found a few wild fruits or cooked meat from the phantom space to eat, and fortunately, Tang Feng came to Quting Mountain this time to prepare a lot of daily necessities, otherwise he would have been blocked in the beast tomb and really didn't eat or drink.

In the depths of this beast tomb, there is not much light at all, it can almost be said that the eyes are black, if it weren't for Tang Feng's better eyesight, he would really be blind. I don't know how deep the canyon is, and the top is entwined with vines, and only faint traces can be seen when I stand here.

In the first few days, the roars of those spirit beasts outside the beast tomb almost never stopped, especially the howls of the howling wolf, but gradually, these roars became scarce, until they finally disappeared completely.

Those spirit beasts should be impatient to wait outside, they can't wait outside the beast tomb day and night, although they are spirit beasts, but they also have their own things, need to hunt, grab territory, fight for mates or something, how can they stay outside all the time, I just don't know if the howling wolf is gone.

Tang Feng's injuries are also healed, the broken muscles have been repaired, the broken bones in his chest have also healed, and his strength has also recovered to the peak period. It was just that he couldn't see the light for so long, which made him a little annoyed.

Moreover, Tang Feng didn't dare to walk out of the beast tomb now, he was really a little afraid of the howling wolf, in case the howling wolf stayed in front of the beast tomb and didn't leave, wouldn't he go out into the wolf's mouth?

Tang Feng wanted to wait for Ling Timid Yan to wake up before leaving, her perception of spirit beasts was extremely keen, with her, she could avoid spirit beasts and leave Quting Mountain safely.

However, looking at the appearance of the spirit of the cowardly Yan in Gangxin, there is not much difference from the beginning, the two wisps of spirit are still entangled, and the degree of fusion does not seem to be a small half, according to this calculation, I don't know how long I will have to wait.

Staying in this place, there was nothing else to do except cultivation, and even wanting to lie on the ground and count the stars became a luxury.

One day is cultivation, two days is also cultivation, except for sleeping time, he is cultivating all the time, even if Tang Feng has a good temper, he feels a little boring.

If you change places, Tang Feng may be fine, but he can't see his five fingers here, making him feel like he is being locked in a cage, which makes people feel a sense of rejection for no reason.

To this day, Tang Feng couldn't calm down and cultivate no matter what. This kind of thought of rejection is equivalent to the appearance of a demon, if you don't guide yourself, forcing yourself to cultivate, not only will you not achieve much results, but you may also make yourself more anxious.

So Tang Feng gave up cultivating the trick of impermanence very familiarly, sat on the ground and thought for a while, wanting to find something to do for himself, stretched out his hand to open his phantom space, and Tang Feng probed to take a look inside.

Well, there's a lot of space, and there's a lot of baby.

Heavenly soldier daggers, Gangbing soft swords, a lot of hidden weapons and darts, as well as those self-defense mechanisms that were specially made to deal with Ye Shenqiu last time, as well as pots and pans, water, rice, oil and salt...... It was the first time that Tang Feng had come to check his phantom space so carefully, and he was dizzying for a while, and now whoever gave him something shiny, he could treat it as a treasure.

Looking to the side again, in a corner of the space, there was a pile of round Neidan, and the energy stored in it was mixed.

Seeing these Inner Dans, Tang Feng's eyes lit up! An idea involuntarily crossed his mind, although he was not cultivating now, he could use the energy of these Inner Dans to refine his physical body for the second time.

After refining the physical body for the first time, Tang Feng felt the benefits brought to him by the improvement of the physical quality. If it weren't for that foundation, after borrowing the power of Bian Wuxue, the injuries he suffered would definitely not have recovered so easily.

With his current physical body, he really can't withstand the energy of the Heavenly Rank Master for a long time, what if he tempers it again? What if he tempers his physical body more powerfully? There is always a degree to which he can withstand it.

Since his current body can't withstand the energy of a Heaven Rank master for a long time, then find a way to make it able to withstand it! The killer weapon of borrowing corpses to resurrect souls must still be used before he is not strong enough. This time it's lucky, I can run to the beast tomb to avoid the pursuit of the spirit beast, and next time I won't have such good luck, once I provoke a powerful enemy, after my killer ability dissipates, I can only become a salted fish on the chopping board, and let others slaughter!

As long as his body could withstand the ravages of the energy of the Heaven Rank master, Tang Feng dared to guarantee that the backlash after he cast the killer weapon would be reduced to a minimum.

Thinking of this, Tang Feng was full of energy, swept away his previous anxiety and irritability, and took a bunch of Neidan from the phantom space.

Each Neidan is equivalent to a Yin Soul. The four most powerful Inner Dan Tang Feng was reluctant to use it, because he didn't know if the Inner Dan of the spirit beast had any other effects, so he left it there first.

Holding the Inner Dan in his hand, he didn't even need to run the exercises of condensing the Yin Soul, but in an instant, all the energy in the Inner Dan was absorbed into the body.

In just a moment, Tang Feng absorbed the energy of hundreds of Inner Pills.

The meridians and dantian all had a feeling of swelling, and Tang Feng suppressed these energies and did not let them be absorbed by himself. The periphery of the body, like that time, agitated uncontrollably, and a breeze rolled up on the ground.

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

After absorbing more than two hundred Inner Dans in one go, Tang Feng nodded and said to himself, "It should be about the same." ”

There was a little pain in the meridians now, although it could be absorbed again, but Tang Feng decided to take it slowly.

Taking a deep breath and preparing to endure boundless pain, Tang Feng activated the impermanence technique, pushing the energy in the meridians and dantian fiercely in all directions, advancing every angle of his physical body and infiltrating into the five internal organs.

This process was much harder than the last time, and the last time Tang Feng was refining his physical body while cultivating. But this time, he wanted to give up cultivation and just refine his physical body.

After all, he had just broken through to the Xuan Rank, and if he let these energies precipitate into the dantian, he would only let his realm climb up, so Tang Feng had to work hard not to let any trace of energy precipitate in the dantian, just drive them into his body.

The tempering of the flesh is limitless.

As soon as the huge energy entered the body, it wrapped every tiny part of the body and tempered it fiercely.

Although it was still painful, Tang Feng felt much better than the first time. I have experienced too much pain during this time, and I am now more and more tolerant.

As the energy pressed into various parts of the body was slowly digested and reduced by the physical body, the pain gradually lightened, and the agitated qi outside the body also calmed down a lot.

I don't know how long it took for Tang Feng to feel that the energy he had absorbed was completely gone, and it was all accepted by all parts of his body. After checking the situation in the dantian, Tang Feng was very satisfied for a while.

After all, these energies flow in the meridians, and they also have to pass through the dantian, so they naturally have to be absorbed by the dantian, but under the urging of their own strength, the part of the energy absorbed by the dantian is very small, almost negligible. In other words, ninety percent of the energy absorbed this time was used to refine the flesh.

After resting for a long time, and casually getting some food to restore his strength, Tang Feng took out two hundred inner pills from the phantom space, absorbed them all, and then entered the process of refining the flesh.

A few days passed, and there were not many Inner Dans that Tang Feng had found, only four of the most powerful ones remained, as well as a few sixth-order and more than twenty fifth-order ones, and the others had all turned into scraps.

In the past few days, Tang Feng has tempered his physical body five times, and he has refined the quality of his physical body to an unimaginable level. It's a complete form of self-harm, but it gives me a huge boost.

Standing up and touching the side wall of the canyon next to him, Tang Feng stretched out his hand to test it, feeling that what he touched should be a stone, and it was a relatively hard stone.

Tang Feng calmed down, stood in front of the side wall, and threw a punch sharply, smashing straight towards the side wall.

"Boom!" There was a loud bang, stone chips splashed, Tang Feng's body did not move at all, and his entire fist smashed into the stone, up to his wrist.

Not only that, but the sound of breaking the sky brought by the fist wind turned out to be like a cloud-piercing arrow, making a loud sound.

For this punch, Tang Feng didn't use his strength, relying on speed and strength.

Slowly pulling his fist out of the side wall, he saw that a hole had been smashed out of the side wall, and there were clearly visible cracks in all directions.

Clenched his fists, Tang Feng not only didn't feel pain, but his whole hand didn't even have the slightest damage, not even the skin was broken.

Taking out a flying knife from the phantom space, Tang Feng threw it out in the direction of the exit of the beast tomb, and in the dark beast tomb, a spark after friction suddenly flashed, and it flew out of a distance of dozens of zhang in the blink of an eye, I don't know what was blocked by something, and there was a crisp sound.
