I have to say that this strange beast is really hard bones.

Lin Nan didn't know how to position the two strange beasts he had killed, but in terms of strength, a few Xuan Immortals together thought they could kill each other.

When refining the weapon, the hardness of the ore will also increase with the increase of the grade, but not every ore will be very hard, but according to different characteristics, the combination of immortal weapons is the strongest.

And this beast bone, to be honest, Lin Nan even felt that this was the Titanic in the refining materials.

The Red Lotus Karma Fire mercilessly burned this thick beast bone.

If it was an ordinary refining material, it would have already turned into a puddle of liquid at this time, but this beast bone was different.

Due to the different properties of the materials, what Luo Yi hopes more is to extract the essence of it and integrate it into the immortal weapons that have already been refined.

In the process of refining, Lin Nan found out.

Although this thing has been strengthened by the source qi for a long time, and it is even possible that it has been growing in the environment of the source qi since birth, but this bone can still be decomposed by the refining technique of the immortal realm.

In other words, even if their cultivation system is completely different from the immortal realm, they still live in the immortal realm and need to follow the laws of the immortal realm.

In that case, it's much easier.

When this bone was broken down into tiny dust by Lin Nan, under the "coercion and temptation" of the Red Lotus Karma Fire, it was integrated into an ordinary six-rank immortal sword little by little.

That's Lin Nan's practice, and he usually puts it in the token, maybe he will use it, such as now.

On the premise of not being sure what would happen after the combination of this beast bone and the immortal weapon, Lin Nan would not directly take Shen Yun and put them on the immortal weapon.

And the next reaction also made Lin Nan once again praise his caution.

Under Lin Nan's refining, the bone meal was perfectly combined with the fairy sword, but another problem soon appeared.

These bone meals, instead of enhancing the power of the fairy sword, weakened it, and it kept weakening.

Why is that?

Could it be that these bone powders can't be assimilated into the fairy sword?

After all, it's a bone that has been strengthened by source qi.

Lin Nan guessed.

As for this immortal sword, Lin Nan put it aside for the time being, wanting to see what kind of changes would occur in the end.

Failure is not terrible, but giving up is embarrassing.

The animal bones of the two corpses, except for Lin Nan who gave Guo Yu a little to study whether they could be used for medicine, all the others were in his own hands, and hundreds of experiments were still done.

Taking out a small notebook, Lin Nan began to record.

"In the first experiment, the beast bone is suspected to devour the fairy sword itself, and the specific results are to be determined......"

Now that the fairy sword around him is still slowly changing, Lin Nan can clearly feel that his texture is becoming brittle and hard, and if this continues, he may be able to shatter the sword body with a flick of his fingers.

Once again, he took out a beast bone and threw it into the refining furnace.

This time, Lin Nan took out a fist glove.

It was refined when I was learning the five-grade alchemy technique before, except for some of the metals, the rest were made of animal skins.

The time of a stick of incense passed.

Next to the fairy sword, there was an extra glove that was faintly emitting green light.

"In the second experiment, the animal bones are suspected to be assimilated with metal and animal skins, and the specific results are to be determined......"

The previous immortal sword was still changing, and if Lin Nan was to judge, it would probably only be at the level of a second-grade immortal weapon.

This is falling a little fast, I don't know if it will rise later, or it will be completely abandoned.

Lin Nan felt that there might also be rejection.

The third time, Lin Nan took out two beast bones alone.

A leg bone, a rib.

With the leg bones as the main body, the ribs as the auxiliary, and a little bit of animal skin, Lin Nan directly began to refine it.

Bone weapons were the only weapons used in people's hands before the advent of bronze objects.

Just like Lin Nan returned to the past of the Immortal Realm at the beginning, the weapons used by humans at that time were all made of bones.

Squeezing, grinding, refining, a small bone knife, refined.

The handle is made of animal skin, which not only increases friction and can make people hold more firmly, but also reduces the shock in the event of a combat collision and prevents the bone knife from falling out of the hand.

This time, the materials are completely refined from the materials on the alien beasts, and the effect is indeed quite different.

In Lin Nan's perception, this immortal weapon weakened a little slower.

"In the third experiment, it was made of animal bones and skins, and the strength of the immortal weapon was still weakening, and it was suspected that in the immortal environment, it was impossible to use the source qi material refiner. ”

This was the conclusion that Lin Nan had come to in combination with the first immortal sword that had completely become a mortal soldier and was so fragile that it could be shattered into powder with a light grip in his hand.

Touching his chin, Lin Nan didn't consider refining with materials in the small world for the time being, where decades had only passed since the transformation of source qi, and the effect of the transformation was not enough at all.

If you want to use materials full of source energy, you have to use the things you brought out of the ancient battlefield.

Lin Nan didn't bring the refining weapon before, mainly because the things he picked up from the ancient battlefield were just ordinary stones.

Although these stones are much harder than many second-grade immortal weapons in the fairy world, they are just stones after all, and they can't extract much metal, and they may not even have them.

Forget it, let's try it first.

A large number of stones were thrown into the refining furnace by Lin Nan, and the refining furnace was about to cry.

Accompanying Lin Nan all the way from the Linxian Realm to here, how many times he had blown up the furnace, even the refining furnace himself had not counted, but now, this was the first time he had refined stones.

Under the scorching of the Red Lotus Karma Fire, these stones didn't even have a chance to smoke, and they were directly burned without a trace.

Hundreds of stones, large and small, were refined by Lin Nan into a small pool of liquid with only pigeon eggs.

It was all the metal elements extracted from the stone, which were forcibly fused together by Lin Nan.

Even, even the little bit of source qi contained in the stone was wrapped and protected by Lin Nan with his divine sense.

The spirit plant brought out from the ancient battlefield before, in the process of alchemy or medicine, the source qi contained in it dissipated directly when the spirit plant changed, and it didn't seem to have the ability to devour the surrounding immortal qi.

Lin Nan speculated that it might be because of the lack of origin.

Throwing the bone knife that had been refined before, Lin Nan refined the puddle of liquid and source qi into the bone knife.

Due to the scarcity of quantity, only the metal liquid could be attached to the surface of the bone knife, and the source qi penetrated into the inside of the bone knife, and even in order to prevent the source gas from leaking, Lin Nan also added a seal inside the bone knife.

"In the fourth experiment, the bone knife did not weaken the reaction, and there are three places that can be speculated at present, one is metal, the second is the source qi, and the third is the sealing ......."

Picking up the small notebook, Lin Nan began to record again.
