In the end, Lu Fan didn't go back directly, but clicked on the light curtain in the unknown material processing area and began to check the list of unknown materials.

Browsing through the detailed light curtain of unknown materials, which listed the images and origin descriptions of various unknown materials in detail, it was not until he really started to read it that Lu Fan realized that even if he had two "Grass and Tree Foundations", it would not have much effect.

Because of the things in these unknown materials, even if it is Lu Fan, he has not seen it, and he is not to blame, after all, many of the things in them may not even be materials at all, just a strange-looking stone on the side of the road.

Suddenly, Lu Fan stopped his finger sliding the light curtain, and his gaze fell on a dusty stone, which was about the size of a walnut, and the ash was not shiny at all.

But on the surface of this stone, there are some patterns that are indistinct, some of which are like natural cambium patterns, but more like traces of erosion by time.

Such a stone is inconspicuous in this pile of unknown materials, and it can even be said that it is no different from a small stone on the side of the road.

Click on the light curtain, the introduction of this stone is very simple: "Unknown material, picked up next to the volcano, see the unique pattern, put it here and wait for someone to take him away, price: 1000 contribution points." ”

Lu Fan pursed his lips, this person said it in a high-sounding manner, but in fact, he didn't know this thing, otherwise, how could he put it here.

1000 contribution points is a lot in the White Tower, but Lu Fan bought it without any hesitation.

Lu Fan, who had gained something, was even more interested in Taobao among the unknown materials, anyway, he needed to wait for the staff of the White Tower to send the stone over, and he still had a lot of time to check the list of unknown materials.

It didn't take long for the staff of the White Tower to send the stone that Lu Fan fancied, and the staff looked at Lu Fan with a very respectful look, in the past month, he had sent Lu Fan countless times I don't know how many materials.

Regarding Lu Fan's status in the White Tower, except for Bai Lei and a few others, I am afraid that he knows a little more.

When the Bai family's frontline base was not established, he worked in the White Tower of the Federation, and after the establishment of the frontline base, he also came over, in fact, this is also normal, the frontline base is very important, and it must be reliable old people, and it is normal for them to come over with the old people of the White Tower of the Federation.

But he has worked in the White Tower for more than ten years, and he has never seen anyone who can continuously ask for a large number of various materials, but the high-level of the Bai family is a green light.

After handing the dusty stone to Lu Fan, the staff respectfully left the unknown material processing area, working in the White Tower for many years, what to ask and what not to ask, he was still very measured.

Holding this dusty stone in his hand, Lu Fan couldn't help but feel a surprise in his heart, he could be sure that the stone in his hand was the Nirvana fruit mentioned in "The Foundation of Grass and Trees".

Lu Fan carefully stroked the stone with his hand, and there was a comfortable feeling of friction on his hand, like a natural frosted material, which is difficult to describe in words, but as long as you feel it, you will understand it instantly.

This also made Lu Fan more sure of his guess, this must be the fruit of Nirvana.

The Nirvana Fruit is not a material, and even the Nirvana Fruit itself is a piece of waste, because the Nirvana Fruit is a seed, and the seed itself is really useless, but the Nirvana tree that grows from the Nirvana Fruit is a rare treasure in the world.

The trunk of the Nirvana Tree is the best material for making runic weapons, and the leaves of the Nirvana Tree are the main medicine that is indispensable for refining a variety of high-grade healing elixirs.

However, the growing conditions of the Nirvana Fruit are extremely harsh, and the Nirvana Fruit does not grow in the land like ordinary plants, but can survive in any environment, of course, provided that it has a strong fire energy.

And this, at least Lu Fan can't do now, the so-called rich fire energy is not an ordinary rich.

However, it is always good to be able to get this kind of treasure, Lu Fan was satisfied with the Nirvana Fruit in his arms, and then continued to check the list of unknown materials.

In a low building not far from the White Tower, Bai Lei looked at the 15-handled wind-type shooting gun brought back by Bai Ling with some excitement, Bai Lei is not like Bai Ling, just a pure manager, he is also a three-star entry-level cultivator, and he is only half a step away from professional-level cultivators.

In between, Bai Lei skillfully took a wind-shaped shooting gun from Bai Ling's hand, played with it in his hand, and then nodded to the distance.

At this time, more than 100 meters away from Bai Lei, a target was raised, these targets were made of special materials, and there were energy sensors on the target, which could accurately calculate the power of the energy rays shot on the target.

Although he had long heard that the wind type could shoot a gun, and even seen it with his own eyes, after all, he had not tested it himself, and Bai Lei was still very excited.

There was nothing in the majority, Bai Lei raised his hand to be an energy ray, and the first test was a power test, so Bai Lei only shot one shot and stopped.

Shout!

The sudden screaming sound startled Bai Ling on the side, and a pale cyan energy ray shot out from the wind energy spear in Bai Lei's hand, leaving a pale cyan trace in the air.

Bang! Syllable!

First, the sound of energy rays colliding on the target, and then the crisp sound of energy rays passing through the target and hitting the exterior wall of the building.

Bai Ling looked at the target with a hole in the center with some surprise, although he didn't cultivate, he also knew that the target, but it could withstand the attack of 1500 pilars, which was already equivalent to the full force of a one-star professional-level cultivator.

And Bai Lei, at this time, is only a three-star entry-level.

Bai Lei couldn't hide the joy on his face: "Hahaha, hurry up, test the rate of fire." ”

However, when dozens of targets rose in front of Bai Lei, he found that the wind type gun in his hand had melted, and he remembered that the wind type could shoot the gun, but it was only an apprentice-level gun.

Don't say that the runes engraved in Lu Fan's current realm can't withstand such energy at all, even if Lu Fan's runes can withstand it, the materials used to make shotguns can't withstand it.

Therefore, just like Bai Lei's hand, the wind-type energy shooting gun has become a pile of runes and materials that have all melted.

Touching his nose, Bai Lei had a feeling that his heart was dripping blood, there were only 15 guns that could shoot guns a month, and he actually wasted one, this kind of good thing, even a little damage was enough to make him sad, not to mention complete damage.

Picking up a wind-type shooting gun again, Bai Lei took a deep breath, looked at the floating and moving targets in front of him with all his attention, and tried his best to control his energy.
