Seeing the Nirvana Pill in Lu Fan's hand, a gleam flashed in the old man's eyes: "This bottle of Nirvana Pill was refined by you?" ”

"Exactly!" Now is not the time to hide.

The old man looked at Lu Fan seriously, but his eyes were full of doubts, obviously he didn't think that Lu Fan would be able to refine the Nirvana Pill.

"Okay, you can enter the Danta."

After a while, the old man took the Nirvana Pill and handed Lu Fan a token, but did not say anything more, just nodded slightly, signaling that Lu Fan could go in.

Lu Fan has already inquired clearly, in Donglin City, the so-called spirit crystals of these people are actually ores similar to energy crystals, but the spirit crystals here are much worse than energy crystals, perhaps, the medium-grade and high-grade spirit crystals they are talking about can be compared to energy crystals.

And the price of a bottle of Nirvana Pill is 10,000 lower grade spirit crystals.

"What grade of Dan Master is 10,000 spirit crystals for life-saving assessment?" Lu Fan didn't go in immediately, but asked with some curiosity.

The old man glanced at Lu Fan lightly, if it wasn't for Lu Fan taking out the Nirvana Pill, maybe he wouldn't have said more nonsense at all.

"10,000 lower grade spirit crystals are just the cost of entering the Dan Tower, the Dan Tower has six layers, the first layer is a first-grade Dan Master, the second layer is a second-grade Dan Master, and the sixth layer is a six-grade Dan Master, as long as you can pass the assessment of the first layer, you can enter the second layer, and if you pass the second layer, you can enter the third layer, and so on, if you fail on that layer, you will be teleported out on which layer."

Lu Fan suddenly realized that 10,000 spirit crystals were not the cost of an assessment, so it was not too expensive, after all, the medicinal materials for alchemy were provided by the Danmeng, and the elixir obtained from alchemy was owned by the alchemist.

Lu Fan didn't talk any more nonsense, and walked in from the hall, behind the hall, a six-story four-cornered tower-like building appeared in front of Lu Fan, there is no doubt that this is the so-called Dan Tower.

In front of the Danta, two middle-aged men were sitting, and behind the two middle-aged men, stood two pretty girls, the girls were holding wine jugs, one of them was pouring wine for another middle-aged man.

From the bodies of the two of them, Lu Fan smelled a faint smell of medicinal herbs, presumably, these two people are also alchemists, and the level is probably not low.

"Enter the Danta, insert the token into the groove, select the pill you want to refine, and the medicinal herbs will be transmitted to you, and when you are teleported, you will fail."

"Remember, you only have three chances to complete each floor, and if you don't finish it beyond the time limit, you're also considered a failure."

Hearing this, Lu Fan hugged the two of them: "Thank you!" ”

When Lu Fan's figure did not enter the Dan Tower, the two middle-aged men showed a hint of a smile, but there was a faint mockery in that smile.

After taking a sip of wine, one of the middle-aged men said: "It's really a big wrong, I spent 10,000 Lingjing just to see what Danta looks like, I bet he won't be able to pass the first layer." ”

Another middle-aged man also smiled slightly when he heard this, and also took a sip of wine, obviously agreeing with his companion's guess, because alchemy often requires a lot of time and resources to practice before it can be achieved.

When they saw Lu Fan's age, the two of them were no longer optimistic about him, and when they reached their realm, they could see at a glance that Lu Fan's true age was true, not to mention, Lu Fan did not have a medicinal fragrance on his body.

In fact, it is the taste of medicinal herbs, but they call it medicinal fragrance.

"It should be a disciple of a certain big sect, 10,000 spirit crystals, even if it is Lao Tzu, so many spirit crystals are lost, and it will hurt my heart."

"Isn't it, if I can break through to the Fourth Rank Dan Master at any time, I don't have to stay in this broken place all the time."

The two began to drink and chat again, although today is the day of the annual assessment of the Dan League, but in fact, many Dan masters have already been assessed, and a year is not enough time for them to make a major breakthrough, they will not talk about 10,000 spirit crystals every year to try.

Many Dan masters have tried many times by themselves, and after finding that there is no problem, they will hand over the spirit crystal to come to the test, so today, except for Lu Fan, there are no more than five people who come to the test, and the task of the two of them is very leisurely.

Entering the Dan Tower, Lu Fan found that there were still a few people inside, and he was slightly stunned, and immediately understood that this place was not for him to test alone, and it was normal for others to have others.

Following the example of the others, Lu Fan also found a place for alchemy and sat down, and inserted the token into the groove in the seat.

Before Lu Fan could figure out what the situation was here, a white light suddenly lit up in the Dan Tower, and after looking closely, Lu Fan realized that it was actually a Dan Master inserted in the seat token.

"What does white light mean? It stands to reason that if you don't pass, you should light up the red light, and if you pass, it should be green, what does the white light mean? ”

Lu Fan was a little helpless, this place is obviously different from the earth, but there is no doubt that there is no technology here, but the use of rune technology here is many times more advanced than that of the earth.

For example, at this time, they conducted the Danshi assessment, Lu Fan did not find any traces of technology, there were all runes here, but it worked, and it was even more magical than the technology of the earth.

Without waiting for Lu Fan to guess, the owner of the token, a white-haired old man, collected four pills from the pill furnace in front of him, swept the pills on the white light, and then a white light appeared, and the old man disappeared into the distance.

You don't have to guess to know that the old man should have succeeded in alchemy, otherwise he wouldn't have shown such an excited expression.

And the rest of the people in the first layer of the Danta all looked in the direction of the old man with envy, and they were able to pass the Dan League's first-grade Dan Master assessment, compared to the Dan Master who did not pass the Dan League's assessment, their identities were like a world of difference.

There was even a person who was distracted because of the movement on the old man's side, and the pill he refined made a mistake, and a scorched smell came.

This time, before the token could light up, a white light flashed, and the man was directly teleported out, and it seemed that he had wasted three chances.

Lu Fan couldn't help but secretly slander, these people didn't know how to distinguish them by color, if he couldn't see the expressions of these people, he couldn't guess whether these people were passed to the upper layer or passed out.

After observing for a while, Lu Fan probably figured out what was going on, so he focused on his seat again.

After inserting the token into the groove, a light curtain appeared in front of Lu Fan, which was very similar to the earth's technology, but Lu Fan could still feel the obvious difference from the energy fluctuations from the light curtain.
