With the end of the Baibao Pavilion auction conference, the originally lively Huangtian Street has become a lot deserted at the moment, and Tang Feng walked on the street alone, naturally he was not in the mood to browse and watch again.

He looked at it and finally made sure that no one was following him, so he turned around and headed south.

There is a building in the south of Huangtian Town, the reason why it is called the next day is because this homestay is isolated from the world, not because this folk custom is not accessible to outsiders, but because of the formation inside.

The Next Sky Tower is also a product of the Hundred Treasure Pavilion, and the entire building itself has a very powerful formation, and each room also has its own formation to isolate each other.

The reason why this is done is to facilitate the martial arts monks to have secret conversations or cultivate here, because there is a protection of the formation prohibition, so naturally there is no need to worry about being disturbed and snooped on.

This kind of folk customs is similar to the restaurant in a sense, but it is more advanced, of course, the price is expensive, the accommodation here is calculated by the hour, an hour a medium-grade spirit stone.

This price can be said to be very expensive, but in some cases, martial artists need it very much, such as the current Tang Feng, who needs such a safe and secret place.

This place was told to him by Tian Huacheng before, and he also proposed to come and settle down in the next day, but the accommodation price was too expensive.

The next day the building was in a river bay, the area was not too big, and there were not many rooms, but there was a forbidden formation, even Tang Feng could not spy on the situation inside.

"If you want to come to this place, it's safer!" Tang Feng nodded slightly, and then stepped into the next heavenly building, and after paying for twelve more medium-grade spirit stones, he decided to stay here for a while.

The reason why he decided to stay in Huangtian Town for the time being was because he felt that he was on the verge of a breakthrough, and he only needed a little retreat to make a breakthrough.

And then there was the Heavenly Soul Stone, he also needed to find a quiet place to refine it as soon as possible to improve the realm of the Great Yan Star Decision.

The room turned out to be a separate courtyard, not only the landscape inside is very exquisite, but the aura here is much thicker than the outside world, it seems that the money is not unjustly spent.

"Objectively, this is your courtyard, there is a formation prohibition switch in the hall, and if you open it after you enter, it is a half-step platform, and it can't be snooped on from the outside. "A guide introduced.

"It's hard work!" Tang Feng nodded slightly.

The half-demon monk who didn't know what kind of demon race and human race was mixed with a human race smiled faintly, didn't say anything more, and left with a pinching of his waist.

Tang Feng then entered the hall, opened the formation prohibition according to the instructions, and then walked out again, standing in the courtyard, and then mobilized all the points of light in the Heavenly Spirit Palace.

He found that even if it was his own Great Yan Xingchen Decision, he couldn't peek into any movement inside.

"That's good!" Tang Feng nodded, and then re-entered the hall, now that he was unfamiliar with life outside, and he had just killed Jing Jiubo, he had to be extra careful.

With this courtyard set of formation forbidden guards, Tang Feng is a lot more relieved, the decoration of the single-family courtyard is very exquisite, and there is everything in it, but this is not the time to relax.

Tang Feng looked around, and after making sure that there was nothing unusual, he then sat down cross-legged, and with a move of his right hand, with the flash of silver light, more than a dozen high-grade spirit stones appeared in front of him in turn.

These dozen or so high-grade spirit stones are now all his net worth, and the reason why the heaven and earth spirit stones are precious is that they are regarded as circulating currency by the martial artists of the great world, and the most important thing is that they have their own value.

The greatest value of the spirit stone is that it can be directly absorbed and cultivated by the martial artist, or used to replenish the spirit element of the dantian at a critical moment.

"Now that we have reached the threshold of breakthrough, I think it should be enough to have these dozen top-grade spirit stones!" Tang Feng shook his head and smiled bitterly, in fact, he had already understood that a beginner-level martial artist in the Yin-Yang Transformation Realm would not need so many top-grade spirit stones at all when he broke through.

After all, the quality of the top-grade spirit stone is very high, and the aura contained in it is not only huge and pure, of course, this is for ordinary Yin and Yang realm martial artists, Tang Feng is special after all.

Every time he breaks through, he needs much more spiritual power than a martial artist of the same level, and even a martial artist who is a great realm higher is far less than him.

This also means that it is more difficult for him to break through than a martial artist of the same level every time, but it also has the advantage of allowing him to fight beyond the ranks.

Fortunately, he has a Divine Fire Furnace, and the speed of absorbing spiritual energy is countless times faster than that of a martial artist of the same level, Tang Feng frowned slightly, and as his hands were sealed, there was a rumbling sound in the air, and the Divine Fire Furnace emerged.

The Three Thousand Furnaces were created by the Divine Fire Furnace, possessing a majestic devouring power, and once mobilized, the high-grade spirit stones arranged on the ground in turn immediately emitted one after another.

The entire hall immediately surged, fortunately, there was a formation forbidden guard here, and it was impossible to perceive it outside, just a few breaths, and the spiritual power in the dozen or so high-grade spirit stones on the ground was absorbed and turned into piles of powder.

Through the refining of impurities in the furnace of divine fire, wisps of spiritual origin entered the dantian through the eight veins of the Qi Sutra and transformed into yin and yang spiritual elements.

The next moment, Tang Feng's aura began to skyrocket, directly breaking through from the first level of the Yin and Yang Transformation Realm to the second realm.

The vast dantian like the sea was still roaring and churning, but the aura contained in more than a dozen high-grade spirit stones had been consumed and could not continue to be replenished, and soon the churning dantian was quiet again.

"It's a pity, a dozen top-grade spirit stones are far from enough, if there are enough spirit stones, there are seven or eight hundred, maybe you can break through to the Yin and Yang Triple Realm!" Tang Feng shook his head secretly and reopened his eyes.

But no matter what, now that the breakthrough strength has increased again, it means that in the cruel world, I have a little more self-preservation.

After a slight breathing, Tang Feng flipped his right hand, and a pitch-black stone appeared in his palm.

"Heavenly Soul Stone, but I don't know if I can use the Divine Fire Furnace to absorb and refine?" Tang Feng thought to himself, and a bold idea suddenly appeared in his mind.

The next moment, the vast divine fire furnace suspended above his head surged, bursting out with a violent devouring force, rushing towards the jet-black stone in his hand.

It's just that no matter how the Divine Fire Furnace works, this Heavenly Soul Stone is still unmoved, and there is not even a trace of soul power gushing out.

"It seems that the Divine Fire Furnace has no effect on the Heavenly Soul Stone, and sure enough, even the power of the half-step platform can't destroy this Heavenly Soul Stone!"

Tang Feng sighed secretly, pinched the magic seal with both hands and closed the divine fire furnace above his head, and then the seal method changed, and turned to run the Great Yan Xingchen Decision.

At this time, it was still daytime, so he naturally couldn't absorb the power of the stars on the vast heavenly dome, but as soon as the Great Yan Stars were activated, Tang Feng suddenly sensed that wisps of indescribable power poured out from the Heavenly Soul Stone, and then slowly merged into his Heavenly Spirit Palace.

"This is the legendary soul power?" Tang Feng exclaimed.
