Lu Yu shook his palm and smiled lightly, this is already very beautiful, especially when the golden thread is finished, this dragon's tail bone gradually has some changes, especially the tip of the part, which is visible to the naked eye, has become curved and sharp, and even one side has become extremely sharp, it looks like it has 'grown' into a narrow and slightly curved knife.

Now, it has become extremely perfect, more elegant and beautiful than the previous single bone.

But Lu Yu always felt that this blade was still a little imperfect, and it was still a little ...... Not satisfactory.

Looking left and right, I didn't see anything wrong.

But perfection is just a feeling.

Fu Liu couldn't stand it anymore, so he rushed up directly and said, "You are really...... It's too much!"

"Uh...... Why?"

"I said that you should make a less beautiful one, but it turned out that you were good, and it looked better and better, what do you mean? What are your plans? I said that your mind is not right, sure enough, what else do you have to say now?!"

Lu Yu said with a bitter face: "I...... Since you have done it, you naturally have to do it well, and deal with it or play with it casually, which is not in line with my philosophy. ”

"Hmph, excuse!"

"Hey......"

Lu Yu sighed helplessly, then looked at the long knife in his hand, and was suddenly stunned for a moment, and then had a very wonderful idea.

He knew what this knife was missing, something unnecessary, something that was just an ornament, but it was really useful when it came to 'Gu Wu'.

Like what...... Spikes.

There are three uses for the spike, from shallow to deep.

Flower shelves use it, just because when it dances, it looks good, and if a set of knife skills is practiced, the knife spike will really not be wrapped around the knife body or body, the knife spike walks with you, it looks good, and most people use the knife spike is this.

Masters use it, usually hang on the waist as a decoration, but if you really want to use it, it should be used as a binding thread, directly tie your palm and the handle together, so that you can avoid the long knife out of your hand, as long as the weapon is in the body, there is a fight, this method does save a lot of people's lives, because when using the knife, the most tired place is naturally the palm.

As for the people at the grandmaster level, they use it as a balance, using the sword spike as a cat's tail, using it to control the center of gravity between swings, and using it to interfere with the enemy's line of sight when attacking.

That ancient martial arts master taught Lu Yu to see if a sword maker is a master, sometimes just look at his sword spike.

Those who have dense and heavy knives are masters in nine times out of ten, and they can dodge.

Lu Yu looked at the white transparent long knife in front of him, and felt that the knife spike was really necessary.

But what exactly to use to make the spike is another thing that needs to be considered.

If it's too late, I'm afraid it's not worthy of the material of the long knife itself, and if it's just good, but it's not suitable for the long knife, and it's incompatible, it's also not good.

There are a lot of things in Lu Yu's small world, but it becomes very difficult to really find the most suitable thing.

He thought of the dragon's whiskers, the dragon's mouth was full of whiskers, but the dragon's whiskers were far tougher than he had imagined, lacking that agility and elegance.

I also thought of dragon skin, but if it was just dragon skin, I felt that it was a little too simple.

So I was really distressed, but I thought that making this knife spike was much more complicated than making this long knife itself.

After thinking about it, thinking that there was no way to think about it, Lu Yu gritted his teeth, directly entered the state of divine soul, and went to find a helper.

In the small world, there is only Yan Yan who can communicate with him.

Finding Yan Yan, Lu Yu said, "There is such a thing as a magic weapon...... Now the best person in the world knows about magic weapons, it must be you, the magic weapon before should be considered to have been thoroughly studied by you, right? Tell me, I want to make a knife spike now, huh...... Or a ribbon, two fingers wide and more than a foot long, what is it made of, and how is it appropriate?"

Yan Yan had just woken up from a coma, and was worried that Lu Yu was going to enter the short stick again, but he was nervous, but when he suddenly heard him ask, he was relieved, and after thinking carefully, he said, "Actually...... This kind of thing is like an elixir, which is also refined, not like an ordinary tool, which can be done by simple cutting and splicing. ”

"Oh, I see...... Alchemy is indeed not the same as refining. ”

Yan Yan said: "And, listening to what you said, you want a knife spike with a magic weapon at the sample level, then in fact, you don't have to worry about what the sword spike is, you directly refine a magic weapon, and then use it as a knife spike, so that it is reliable." ”

"Huh?"

Lu Yu was stunned for a moment, and then smiled: "Sure enough." ”

After thinking for a while, he said, "How should this magic weapon be refined?"

"I don't know. ”

Yan Yan answered very thoroughly, making the corners of Lu Yu's eyes twitch several times, and endured and endured, but he still couldn't hold back, and reached out to touch her body fiercely.

After a while, it was considered enjoyable, Lu Yu pondered: "Magic weapon, let me imagine carefully, I think there should be similar information in my memory." ”

His statement is somewhat strange, but it is true.

There are many, many memories on the ancient giant ding, and he owes it to him, so how can he talk about it clearly?

Memory is a wonderful thing, because it is a transmission, and the inheritance itself does not have any subjective emotions, which leads to ...... All the information suddenly appeared and poured into Lu Yu's mind, but Lu Yu couldn't know what was important and what was meaningless.

That's equivalent to ......

Two memories, one is a memory of his bank account password, and the other is a morning twelve years ago, there were a few fritters in breakfast, how many were eaten, and a few were left.

The importance of these two memories is self-evident, but this importance is subjective, people use their own experience and wisdom to distinguish, but the memory inheritance does not understand so much, it will be these two memories regardless of any importance, directly with the same amount of information and 'position', neatly instilled into people's minds.

And this kind of large and complex will make people very weak to organize and find the key work.

Lu Yu was very powerless.

Just let those memories pile up in your mind, I really don't want to, and I can't care about it.

But if he wants to find something, as long as he has a specific goal, he can also find it in the sea of memories...... A few.

The refining of magic weapons is extremely complex, varied, and ...... It's very difficult. There are many refining methods, and in today's world, most of the refining methods are ineffective because the conditions do not allow it.

After looking for a long time in it, Lu Yu found one.

Measuring the sky!

It needs dragon whiskers and phoenix blood, yin and yang two ways, five elements of sacrifice, aura through, supplemented by the big mixed element method of refining, which can be achieved quickly.

Lu Yu blinked, then raised his head and looked at Yan Yan with malicious intent.

"You...... What are you going to do? Your eyes are so evil!"

Yan Yan was shocked and hurriedly stepped back.

But he was still a step too late, and Lu Yu grabbed his little arm.

"Hey, hey, I remember...... You seem to have a bit of phoenix essence blood in you, right?"
