Long Tian could feel that he and this cyan Dan furnace already had an inseparable connection, as if they were one.

It's just that he still can't be sure of the level of this Dan furnace, but he only roughly feels that it is at least a high-level spiritual weapon, and it is infinitely useful.

Alchemy is naturally needless to say, Long Tian even has a feeling that if he uses this Dan furnace for alchemy, the Dan success rate and the quality of the pill will increase significantly, maybe it won't take too long, and he will be able to advance to the Seventh Rank Alchemy Grandmaster!

In addition, this Dan furnace is also extremely useful in battle, since it has been refined by Long Tian, as long as Long Tian has a thought, it can appear anywhere within a certain range.

With the hardness of the Dan Furnace at least the level of a high-level spiritual weapon, this is simply an all-round defense treasure with no dead ends, as long as it is not fast enough to exceed Long Tian's mind, or the strength exceeds Long Tian's too much, it is basically impossible to break through the defense of the Dan Furnace.

As for the attack, although Long Tian does not have the attack method of the Dan Furnace for the time being, but with that terrifying weight, if he surprises someone, how many people can withstand it?

Moreover, Long Tian also felt that because of his own limited strength, his understanding and utilization of this Dan furnace was simply far from enough, and it seemed that he was ...... It's just that it exerts one-ten-thousandth of the power of this Dan furnace, or even less.

Therefore, although Long Tian had preliminarily refined this Dan Furnace, he didn't even know the name of this Dan Furnace, so he could only be regarded as having obtained its initial approval.

But even so, Long Tian was already very happy, he had picked up the treasure, this time he really picked up the treasure.

This trip to the Yanluo Valley, even if there is nothing else to gain, but this Dan furnace is already worth the trip, no, it is simply worth the money, and I am overjoyed.

What's more, Long Tian could be sure that his harvest this time was definitely not just this Dan Furnace, because after refining this Dan Furnace, he had already made a new discovery.

Just below the Dan furnace, there was a hidden passage, but the Dan furnace had blocked Long Tian's divine consciousness before, and he didn't even find it, but now that the Dan furnace was refined by Long Tian, that passage naturally couldn't escape Long Tian's divine sense.

The Divine Sense scanned the surroundings again, especially under the thick dust, and after finding that there was indeed nothing missing, Long Tian decided to go down the passage to take a look.

Since he had painstakingly dug out such a passage in such a hot place, and covered the entrance of the cave with such a precious Dan furnace, Long Tian believed that there must be something more precious underneath this passage.

But after entering the passage, Long Tiancai found that his guess might be wrong, because this passage didn't seem to be artificially excavated.

In other words, only a few tens of meters at the entrance of the passage, there are still some traces of artificial excavation, the further down you go, the traces of artificial excavation will gradually disappear, and it is completely a natural appearance.

But whether it was a artificially dug passage or not, Long Tian thought that since someone chose to cover the entrance of the cave with a Dan furnace, there must be a reason for him, if there was nothing in the passage, why use treasures such as the Dan furnace to cover the entrance of the cave?

So Long Tian continued to move downward with firm confidence, but as the passage went down more and more, the temperature in the passage became higher and higher, and in the end, a solid flame-like wave was almost formed.

The surging waves of flames filled the entire passage, Long Tian only felt as if he was surrounded by flames, and the ice attribute exercises could no longer bring him a trace of coolness, and the true yuan in his body was rapidly depleting, but it still seemed that he could not withstand the impact of this flame wave.

It can't go on like this!

Long Tian was completely sure that if he continued like this, even if his true yuan was exhausted, he was afraid that he would not be able to reach the end of the passage, and besides, the temperature in the passage was already so high, and the temperature at the end of the passage was extremely terrifying without thinking about it.

It is never a good way to fight against the flame waves with ice attribute exercises!

Ah......

Long Tian suddenly raised his hand and slapped his head fiercely, he was really confused, he only thought about using the ice attribute technique to fight, why didn't he think of fusion and cultivation?

The air in the passage was filled with almost substantial fire waves, which showed how rich the fire energy was, and if the fire attribute exercises were run in such a place, not only could they be integrated with the environment, but they could even cultivate independently to replenish the consumed true yuan.

In this way, not only does he not have the threat brought by the high temperature and hot waves, but he can also cultivate and strengthen his cultivation by the way, such a good thing that kills two birds with one stone, he didn't even think of it?!

If you think of it, you can act on it immediately.

Long Tian decisively converted the ice attribute exercise into a fire attribute exercise, and sure enough, although there was no coolness, he didn't feel the pain of the hot barbecue, but he just felt as if he was integrated with the surroundings, warm and comfortable.

Moreover, while running the fire attribute exercises, countless pure and rich fire energy surged into from the pores of Long Tian's body, and he couldn't wait to enter the meridians and the dantian, and wandered all over his body along with the operation of the exercises.

The True Yuan consumed before was completely replenished in a short period of time, but the Fire Yuan Power was still pouring in, constantly increasing Long Tian's True Yuan, and improving his cultivation little by little.

Long Tian was overjoyed, this kind of cultivation speed was simply several times that of his usual cultivation, if he didn't want to continue to explore the secrets at the end of the passage, he would almost want to sit down and cultivate on the spot.

But it doesn't matter, Long Tian's Nine Turns Qiankun Gong, even when he is eating and sleeping, can cultivate independently, even if Long Tian doesn't deliberately stop to cultivate, in such a strong fire yuan power, the cultivation speed will not be slow.

Continuing to move forward, the surging waves no longer posed any threat to Long Tian, but instead made him feel like a fish in water, comfortable and comfortable.

Of course, Long Tian also understood that not all martial artists who cultivated fire attribute exercises could be like him, otherwise, the Yanluo Valley would not have buried so many alchemists and sects that cultivated fire attribute exercises.

The real reason should still be due to the Nine Turns of Qiankun Gong, and the level of the Nine Turns of Qiankun Gong is too high, so that it can be inclusive, not refuse, and tame and refine the fierce and violent fire element here.

Otherwise, Long Tian was just a middle-level martial king's cultivation, how could he do something that many sect forces had not been able to do for many years?

This passage is really deep, Long Tian himself silently calculated in his heart, he has gone deep into the ground for about a few hundred zhang, and he has not even reached the end of the passage.
