When he learned that a light source stone could be exchanged for ten contribution points from the hands of the dream shopkeeper, Fang Tiannan became no longer worried about whether he could become an outer disciple of the Qingyun Sect. However, in order to hide the characteristics of his ability to absorb light source stones, Fang Tiannan would not be so stupid as to directly exchange all the light source stones for them.

What's more, Fang Tiannan also needed to absorb the warm energy that could improve his cultivation as soon as possible from the light source stone.

Only when necessary, Fang Tiannan would bring the light source stone that had absorbed the energy and exchange it for it to ensure that he could become an outer disciple of the sect.

What made Fang Tiannan extremely curious was that the energy on the light source stone, once absorbed, seemed to be able to continuously improve his physique in his body. Originally, the strength cultivation that was still in the Ming Jin period burst out in an instant, which was completely beyond Fang Tiannan's expectations. And when the energy is running in the body, whether it is the meridians that bear the strength or the dantian that stores the energy, it is much more expanded than before.

Being able to make the energy show its yang attribute is the best proof of it. Fang Tiannan couldn't understand what all this was for. You can only examine your body from an objective point of view.

For example, to test your combat effectiveness among martial artists of the same rank, and whether you are unwell.

For the time being, there was no hidden danger, everything was performing very well, and Fang Tiannan was eager to make himself stronger as soon as possible, so he could only absorb the energy on the light source stone with all his might.

As for what to do after these fifteen light source stones were all absorbed, Fang Tiannan didn't think that far ahead......

According to the usual practice, Fang Tiannan held the light source stone that had not been absorbed in both hands, and the warm feeling on his body appeared clearly again.

Fang Tiannan concluded that in the past two months, in addition to the first absorption in the valley, it was only when he broke through the Ming Jin Realm and reached the Dark Jin Realm that the speed of absorbing the energy of the light source stone became much faster.

On weekdays, no matter how hard Fang Tiannan tried, the energy that passed from the light source stone to his body was very subtle, and it would stop until his body reached saturation.

Because today, most of the time, Fang Tiannan was on the way back to Qingyun Town, and then it was a transaction exchange with the dream shopkeeper, and there was no fierce battle or anything like that, so Fang Tiannan's consumption itself was very small, and after absorbing about half a cup of tea, Fang Tiannan stopped.

Got up from the wooden bed, came to the wooden table, gently moved the wooden table to a position, and then squatted down again, carefully digging up a stone brick under the wooden table, revealing a sealed dark grid.

Although the house where Fang Tiannan lives is very simple in terms of furnishings, the ground in the house is paved with stone bricks, which is extremely clean. There are a few broken stone bricks, but in general, there is nothing unusual about them. It can be said that in the entire residence of Qingyun Town, such an arrangement is very ordinary.

Even when it rains outside, inside the house, it's still clean and refreshing.

In the dark grid, there are the remaining ten light source stones. In addition, there is a small amount of material. These are all Fang Tiannan's special harvests in the past three years. Any item that is exchanged for contribution points in exchange for the dream shopkeeper, as an ordinary child, there is no way to take it back. If you really want to, the price will be higher than the contribution point of the original transaction. Therefore, like Fang Tiannan, many ordinary disciples would definitely not directly trade and exchange with the sect whenever they harvested extremely precious items.

In addition to the light source stone, Fang Tiannan also had three items that were stored in this dark grid.

The first is an ore that looks like a demon beast Neidan. This was discovered by Fang Tiannan when he first excavated several pieces of first-order ice core jade mines. It is similar to the size of a bird's egg, a round one, and the material is not very clear, like an ore, and it is not quite like it. In color, it is a little blue.

The second piece is a root tendril. Originally, when he got it, he picked it up in a piece of dead wood and weeds, Fang Tiannan also thought it was a common thing, but he tried his best, and there was no way to break it, and this cut of whiskers seemed to be full of spirituality.

Restricted by experience and knowledge limitations, most of what Fang Tiannan is familiar with is the information that a martial artist should grasp. Once beyond the boundaries of martial artists, as long as it is not a special material, Fang Tiannan will rarely have knowledge of the Dao. At this point, after becoming an outer disciple of the Qingyun Sect, it should change a lot. In Qingyun Pavilion, there are a lot of materials for children from outside the sect to read, and the price is low.

And the third thing, Fang Tiannan knows. It was a small piece of icy dark iron that Fang Tiannan had obtained at the bottom of a pool in the Netherworld Mountain Range. For the most part, the shape of the Icy Dark Iron is similar to that of most ores, but it is a fourth-order material. For the current Fang Tiannan, this is undoubtedly very precious.

Icy Darkiron can be used as the main ingredient for crafting a real artifact. The real weapon is a weapon that can only be used by a real cultivator, and its power far exceeds that of the weapon used by a martial artist. Fang Tiannan also had the idea of exchanging this piece of cold dark iron, but later, the contribution points of the sect increased steadily and orderly, and Fang Tiannan didn't have that thought.

Good things should naturally be kept for your own use.

At this moment, Fang Tiannan placed the light source stone that had not been absorbed, hesitated for a while, and finally closed the dark grid and buried it back in the ground. Relatively speaking, the things in the dark grid can be regarded as Fang Tiannan's greatest wealth, and it is also where his hole cards have been in the past three years......

With a long sigh of relief, Fang Tiannan sat back on the edge of the bed, took out the detergent that he had exchanged from the dream shopkeeper, held it in front of him, and looked at it carefully for a long time.

Fang Tiannan naturally couldn't see a reason. He was just thinking, hesitating, whether to use this bottle of detergent. In terms of the wealth that Fang Tiannan currently has, there is indeed not much that can provide him with waste. In any case, this bottle of detergent is also worth nearly twenty contribution points.

Subconsciously frowning, as if secretly deciding something, Fang Tiannan's face gradually returned to calm, and instead from his chest, he felt a black metal brand.

The metal brand is not big, it is rectangular, only slightly smaller than Fang Tiannan's palm. At first glance, the metal card will show a touch of quaint atmosphere, the tone is very heavy, and the texture is quite rich. Faintly, you can also see that there is a little vitality overflowing on the metal brand.

Fang Tiannan knew that it was a ban on this metal brand. The reason why Fang Tiannan exchanged the detergent was to break its prohibition. This metal brand was obtained by Fang Tiannan on his most recent trip into the Netherworld Mountain Range, and it was in the small valley where the light source stone was found.

More importantly, the place where he got this metal brand was not far from the place where Fang Tiannan picked up the tail of the third-order earth dragon. It can be seen that there are still a few drops of red blood on the metal brand, which seems to have been inadvertently sprinkled during the battle.

Fang Tiannan didn't know what he would find after breaking the seal of this metal brand, and whether there would be any danger, but the curiosity about the metal brand in his heart kept driving him to urgently know the answer. Immediately, Fang Tiannan's face couldn't help but show a few wry smiles.

According to the dream shopkeeper, it is still unknown whether this sealing agent can break the seal.

Of course, Fang Tiannan opened the bottle of the lotion sealant, and let the potion inside slowly flow to the metal brand, until all the metal brands were surrounded by the potion. Then, Fang Tiannan stared at the metal brand without blinking, to see if there were any visible changes.

It's just that half a quarter of an hour has passed, a quarter of an hour has passed. The metal brand is still the same, not the slightest change.

The potion on the metal plate seems to have gradually evaporated or absorbed due to exposure to air. For this metal brand, the lotion potion that Fang Tiannan poured on it only played a cleaning role. With the passage of time, after the surface of the metal brand became dry again, Fang Tiannan saw that the ancient meaning emanating from the metal brand became more and more obvious, as if telling its existence that it had been for a long time.

The few drops of blood that were still there were all gone.

Fang Tiannan sighed, thinking that this bottle of detention did not show a veritable effect as it was. Fang Tiannan was slightly distressed, and casually put away the metal brand. If he could have known in advance that Lu Dao would be such a result, maybe when he exchanged contribution points with the dream shopkeeper, he would not have taken out the light source stone, but chose to take out this metal brand. In this way, there is no need to exchange for a washing agent later.

It's just that this mood didn't last long, just when Fang Tiannan was still sitting on the edge of the bed, the whole heaven and earth suddenly, as if there was an earthquake, "buzzing", the shaking of the ground, and the tremor came from afar, showing how violent the anger of the earth was.

The house where Fang Tiannan lived seemed to be in danger of collapsing. And the wooden table in Fang Tiannan's house also trembled slightly, the flames on the oil lamp flickered on and off, and Fang Tiannan's feet, which were still on the ground, instantly felt a tremor from the depths of his soul.

Immediately, Fang Tiannan extinguished the oil lamp and rushed out of the house.
