Beast Mastery

After being asked such a cold question by his master, Zhang Nuo's body seemed to have fallen into ten thousand years of mysterious ice. He shivered violently, but his mind was spinning rapidly.

He couldn't understand why he advanced so quickly. Without the "Nine Dragon Sword Box", even if he was given another two years, he might not be able to advance to the sixth level. But in front of Lin Fan, he also

It’s hard to hide it anymore, because no matter what the excuse is, it cannot be justified under the current situation!

"It's because of the 'Nine Dragon Sword Box'!"

As soon as he said this, Lin Fan was startled. Not only Lin Fan, but also Gao Dakuan and the other three looked at Zhang Nuo in surprise. They all knew that when Zhang Nuo chose a magic weapon, he chose one that was almost on the verge of being scrapped.

The ancient artifact "Nine Dragon Sword Box", but what does this have to do with his improvement in cultivation speed?

"Bring the sword box and let me see it!"

Lin Fan still didn't believe it in his heart. After all, the sword box had been in his hands for nearly a hundred years, and during these hundred years, he didn't find anything special.

Hearing this, Zhang Nuo walked back to the stone bed, then picked up the sword box and returned to Lin Fan. After handing the sword box to Lin Fan, the four of them walked towards the hall of the cave.

Sitting on the main seat in the hall, Lin Fan looked back and forth at the "Nine Dragon Sword Box" in his hand. After a moment, he frowned and his drunken eyes revealed an expression of disbelief.

"What did you do to this sword box?"

Lin Fan put down the sword case in his hand, stared at Zhang Nuo and said.

"I haven't done anything, but after the master gave me this magic weapon, I kept it next to my bed. One day when I was practicing at night, I suddenly found that it would automatically turn on at a certain time in the middle of the night.

Gather spiritual energy!"

Zhang Nuo would never tell anything about the "Xuantian Gold-eating Insect". Now he understands even more that this spirit worm cannot see the light. Once someone knows about the spirit worm, his life will be certain.

If he is threatened, he cannot tell anything about the spirit insects even in front of his master.

"Gather spiritual energy!"

Gao Dakuan took a deep breath, while Qu Yuan and Ye Ling'er looked at the sword box with incredible eyes. The most important thing for a cultivator is spiritual energy. The "Nine Dragon Sword Box" can actually gather spiritual energy. Just this one

So far as I'm concerned, it's a priceless treasure!

Lin Fan pondered for a while before speaking:

"This sword box was extremely damaged before I gave it to you. It was difficult to even activate it, let alone gather spiritual energy. But now the sword box has been repaired a little. Although it is not in perfect condition, it is completely usable!

"

Repair! Gao Dakuan and others may not understand this word, but Zhang Nuo really figured out the whole thing at once. It turns out that the crystals produced by the "Xuantian Gold-Eating Insect" can repair the "Nine Dragon Sword Box"

!However, he did not show too much surprise and still looked at Lin Fan pretending to be puzzled.

"When my master gave me the sword box, he once said that this 'Nine Dragon Sword Box' is a divine weapon, and if you want to repair it, you must use the 'Five Color Black Crystal Stone'! But this kind of stone is rare in the world, even if

Occasionally I find some, but only a tiny bit. When I traveled to Tianyuan Continent, after decades, I only found a tiny bit as thick as a hair. It was just that tiny bit, but it cost me tens of thousands of middle-grade spiritual stones.

.”

Having said this, Lin Fan couldn't help but smile bitterly. Gao Dakuan and Qu Yuan looked at each other and were shocked. The main currency circulating in the world of cultivation is spirit stones. As the name suggests, spirit stones are stones containing spiritual energy.

Spiritual stones are divided into four levels: low-grade, medium-grade, high-grade and top-grade. The equivalent conversion between spiritual stones is one hundred times. That is to say, one hundred low-grade spiritual stones can be exchanged for one medium-grade spiritual stone, and one hundred

A medium-grade spiritual stone can be exchanged for a high-grade spiritual stone, and so on.

Low-grade spiritual stones and medium-grade spiritual stones are the most widely circulated in the world of immortality, while high-grade spiritual stones and top-grade spiritual stones are rare. There is no other reason. The higher the grade of spiritual stones, the purer the spiritual energy they contain. Although there are

exchange ratio, but most cultivators are unwilling to exchange high-grade spiritual stones for low-grade spiritual stones.

Tens of thousands of middle-grade spiritual stones, no matter where this number is placed, it is a huge sum! Seeing that everyone was surprised, Lin Fan shook his head slightly and continued:

"But what I didn't expect is that this 'five-color black crystal stone' is not a kind of stone, but is distinguished by color, which are white, black, green, yellow and purple! The five kinds of crystal stones are combined together.

It's called the 'Five-Colored Black Crystal'! The few crystals I collected at the beginning were just white black crystals, which were not enough to repair the 'Nine-Dragon Sword Box'! To completely repair the sword box, a large amount of five-color crystals were needed.

Only Shi can!"

At this time, the bitter smile on Lin Fan's face became even thicker. The crystal stone he had spent so much effort to find turned out to be a drop in the bucket and had no effect on the sword box at all.

"Is that why the master put the 'Nine Dragon Sword Box' into the magic weapon room and never took it out?"

Gao Dakuan looked at the master with some sympathy and said.

"Well! I thought it was a useless magic weapon, but who would have thought that when the sword box was in Nuo'er's hands, it actually repaired itself! Don't you think this is God's will? Maybe I put it in the sword box at the beginning,

Then a little bit of white black crystal will work?”

Lin Fan picked up the wine gourd next to him and drank a few sips of wine before speaking as if he had lost something.

At this time, even if Lin Fan was killed, he would not believe that Zhang Nuo would have a large amount of "Five Color Xuantian Crystals", so he thought that the crystals he put into the sword box had an effect.
