However, in the polishing, he found that he was fortunate that he did not let others polish this superb smelling stone, if he took it to others to polish, even if the other party was very experienced, it was very likely that he would not find the special texture inside, and it was more likely that he would find it, and he didn't want to spend too much effort, but he used such a painstaking polishing method.

This special texture is that this smelling stone is the best of the best ores, and now his expected goal is not to let Xunlong have a search range of 100 miles, but 200 miles.

Therefore, Qin Gang, a master of practicing weapons, spent two hours polishing a simple smelling stone, and he originally expected it to be half an hour.

However, he was also glad that he didn't hand over this sniffing stone to other practitioners to polish, but he still felt that the next time this kind of thing happened, when the item was not very expensive, and the time he used was not much faster than that of others, he could spend some spirit stones and give it to others to do it for him.

This time it's just a crooked hit, and it won't be the case next time.

Seeing this smelling stone that had been polished by him, Qin Gang's mood was very comfortable, and everyone would be very happy with this unexpected joy.

The next thing is to test the skill level of the trainer, and the next thing is to remove the taste, Qin Gang has also come into contact with these skills in that mysterious space, and now is a good time to show it.

As the name suggests, it is to remove the sensitive taste of the olfactory stone and leave what you want.

Yes, these smelling stones can distinguish more than 3,000 kinds of special smells, such as humans, monsters, flowers, and other ores, so these sensitive smells must be removed, otherwise wherever this dragon hunting is made, the information found will be displayed, so that it will lose its effect.

Qin Gang took out a sniffing bottle, which he didn't know which dead monk he had found before, it was a sniffing bottle about the smell of corpses, and with this, he could find corpses.

Many times when Qin Gang sorted out the items in the storage bag, he wanted to throw away this sniffing bottle, because this kind of sniffing bottle was not in much demand, think about who would want a bottle full of corpse breath.

But in the end, he decided to throw it away.

I opened the bottle and was very, very careful to control the flow of the scent with the aura, letting it flow to the polished olfactory stone.

Don't think that this step is simple, it is not simple at all, and if it is not controlled well, the whole piece of smelling stone will become a piece of waste.

This step requires a lot of experience and skill.

Qin Gang controlled it and let it flow in his own direction to the smelling stone, and after flowing through, Qin Gang saw a flash of red light, and he didn't know if it was successful.

He opened the sniffer again, and let the rest of the corpse gas rush to the stone, and there was a strong reaction on it, seeing that this was not completely successful.

Qin Gang took out other sensitive smells again, and saw what the reaction would be when he rushed to it, this reaction was not at all, and seeing this, Qin Gang showed a happy look.

Although the next step was more difficult, it was also half successful, and Qin Gang's mood was quite relaxed.

The next step is to connect the reaction of the sniffing stone with another warning weapon, this warning weapon is already good, although it is very difficult, but unlike the previous step, if you fail, you will completely destroy the material, this step can be done many times, and if you fail, you will basically lose time.

However, here Qin Gang reminded himself that his time is also very precious and should not be wasted.

Thinking of this, Qin Gang suddenly thought of one point, that is, he should continue to take risks, his special substance that can open the mysterious space, Qin Gang has never found what they have in common, it is because of the smell.

As soon as he thought of this, Qin Gang immediately took action, which was one of his advantages.

It was decided to continue to expand its gains, that is, to add a little more.

However, there are two problems in front of Qin Gang, that is, how to refine the smell of that special substance, and how to make the smelling stone add another smell is a very difficult operation, and if you don't pay attention to it, you may ruin the entire smelling stone.

Without much hesitation, he took out that special substance, which was also a stone, even an ordinary stone, basically had no value, but in Qin Gang's eyes, this was indeed a priceless thing, because this was the key to the mysterious space.

The value of the mysterious space to him goes without saying.

Getting the smell of a stone out is also a great challenge for Qin Gang, a master of martial arts.

The smell of the stone is single, Qin Gang doesn't have a sensitive nose, and he doesn't have a demon beast with a keen sense of smell on his body, so he can't get the smell out like those specialized olfactory masters.

And the more difficult thing in front of him is to get the smell of a special substance, and even he himself does not know what this smell is, or even no smell.

However, he looked at it with this attitude, he couldn't get it, and he wouldn't destroy this 'precious key', in his eyes, it must be that the stone that can open the mysterious space is much more valuable than the smelling stone.

Qin Gang's difficulty is to find out something that he doesn't know, and he knows how difficult it is.

At this time, Qin Gang, a person with a lot of ideas, thought of a good idea.

Because this is an ordinary stone, it does have the effect of opening up the mysterious space, and Qin Gang, a busy immortal cultivator, also has a very free time, so he used this time to find the same stone to see what difference they have.

However, Qin Gang naturally didn't come up with any results, but these stones that didn't have that special substance were still quietly staying in his storage bag.

Thankfully, Qin Gang planned to throw out these 'useless stones' the next time he cleaned up his storage bag.

Fortunately, he was disrupted by a few guys from Heiyun Village, otherwise these stones would not have stayed quietly in a corner.

To say that ordinary stones are not found anywhere, in the right place, this kind of stone is everywhere, so many that even if the immortal cultivator can pick it up.

But in the wrong place, you can't buy this kind of stone even if you sell millions of spirit stones.

So Qin Gang feels very lucky, and even now that he has changed his opinion on 'Fate Bitch', sometimes she still likes him quite a lot, and it is difficult for him to have some good luck from time to time.

Take out two identical stones, if Qin Gang hadn't marked them, he might not even be able to recognize them.

Qin Gang's mind was thinking, how to get the smell of stones to get out of this training skill, it can be said that this is a side skill in training, because it is very rarely used.
