"What? the connection between the Evil Dragon Sword and the Skeleton Warrior, there is still something missing?" Ling Tian didn't quite understand what the machine spirit meant.

The machine spirit said helplessly: "Yes, it's just a little bit." We all ignore a problem, that is, skeleton soldiers and evil dragon knives, although they were both artifacts in ancient times, their materials are completely different. ”

"The Evil Dragon Knife is a weapon, and it is still metal in essence, but it is just a superb metal with a better texture. But although the skeleton warrior is an artifact, this guy is essentially a human skeleton, although after many upgrades and transformations, this human skeleton has become extremely hard, compared to the evil dragon knife, but these two materials cannot be fused together at all. ”

"In addition, both the skeleton warrior and the evil dragon knife have their own wills, although the will of the evil dragon knife has been completely refined. But the two sides have been fighting for hundreds of thousands of years, and they are very familiar with each other's breath, so in a short period of time, it is impossible for the two of them to completely fuse. ”

The words of the machine spirit made Ling Tian have a headache, and in this regard, he was completely a novice, and the machine spirit couldn't figure it out, and he didn't know what to do: "Do you have any good methods worth trying?"

The machine spirit said, "I'm here for your help!"

"Help, what can I do?" Ling Tian was very puzzled, he didn't know anything about alchemy and refining, Ling Tian didn't know what he could help.

The machine spirit continued, "I need a metal right now through which I can fuse the two together. However, this kind of metal is not easy to find, and in order to fuse these two guys perfectly, the metal needed must meet two conditions. First, because the Skull and the Evil Dragon Knife are artifacts, the metals that meet the requirements must be comparable in strength to artifacts. Second, quite simply, as the only link between the two, the metal must be extremely malleable. ”

"Both conditions must be met, and one is indispensable. ”

Hearing the request of the machine spirit, Ling Tian wanted to take the machine spirit out and beat it up, why didn't you say these things earlier, now that the refining process is halfway through, it is impossible to stop, in such a short period of time, where can I find you a metal that meets your requirements!

Besides, aren't you too fucking demanding? You're right, these two guys are indeed artifacts, and the metal that connects them must be the best of the best.

However, your requirements are too high, the hardness is comparable to that of an artifact, and it has extremely high ductility, which is completely an attribute that is completely incompatible between two wind horses and cows! How can they appear on the same metal at the same time?

Ling Tian felt that even if there was metal that could meet the requirements of the machine spirit, he couldn't find it!

There is no way, there is also a refining hall in this eternal trial ground, but this refining hall is not within the scope of my own planning and waiting for me at all.

Moreover, even if Ling Tian was to change his route now, it would be too late, because this Refining Hall was extremely far away from here. If Ling Tian went to the Refining Weapon Hall, there was no doubt that he would definitely miss the final assessment ,—— the Ninefold Heavenly Ladder!

Moreover, the most important thing is that the refining hall may not necessarily have this metal that meets the requirements of the machine spirit, because the requirements of the machine spirit are too high.

Ling Tian believed that even in the ancient period, the metals that met the requirements of the machine spirit must have been extremely rare, and it was even possible that they did not exist at all.

However, now it is impossible to stop refining the skeleton soldiers and the evil dragon sword, Ling Tian is about to collapse, it is not easy to find all the skeleton soldiers, but he did not expect that in the end, he may end up with nothing, such an ending is unacceptable to Ling Tian no matter what.

However, at this point, it seemed that all Ling Tian could do was wait for the news of the failure of the machine spirit.

However, although Ling Tian's face was very ugly now, Mo Xiyan didn't notice anything wrong with Ling Tian because he was playing with the little guy very energetically.

"You see, if there are any weapons and magic weapons that we have obtained during this time, it really can't be used, let's go back and see if there is anything on him that we can use. "Ling Tian is a little sick and rushed to the hospital now, and he has hit that monster with all his ideas, which shows that Ling Tian is already very anxious.

You must know that Ling Tian was opportunistic when he got the left leg of the skeleton warrior from that monster, if he had a head-on confrontation with that monster, Ling Tian and Mo Xiyan would not have any chance of winning at all, not to mention that it would be even more difficult to get something down from that monster.

"No, it's useless, I looked at the monster's body at the time, and it didn't meet the standards at all, the skeleton soldier's left leg is the best part, and there is nothing comparable to it. The tone of the machine spirit was also slightly disappointed.

However, Ling Tian's words reminded the machine spirit, and the machine spirit suddenly remembered that there was something that really could meet his requirements.

So he immediately found the two gates that Ling Tian had brought in the Divine Beast Garden.

The machine spirit remembered that there seemed to be a few pieces of ice iron on top of those two gates.

Originally, the Ice Iron alone did not meet the conditions of the machine spirit, and although it reached a level comparable to the artifact in terms of strength, it was not malleable enough.

However, it suddenly occurred to the machine spirit that since those few pieces of ice iron could be used as the junction of the two gates, it proved that its malleability was good enough.

After the machine spirit found out the few pieces of ice iron and studied them, he finally breathed a sigh of relief.

Because these pieces of Ice Iron fully meet the requirements of the machine spirits, but to be precise, it is no longer appropriate to call them Ice Iron now.

After repeated observations, the machine spirit was determined, although the main ingredient of this thing was cold ice iron. However, after careful observation, the machine spirit determined that there were still some ingredients in this cold ice that he didn't recognize, but because the ingredients of this kind of thing were very small, the machine spirit didn't see it before.

However, although this thing machine spirit is not recognized, it can be determined that it is because of the existence of such an unknown thing, although the amount is also very rare, that the cold ice iron, which was originally very malleable, meets its own requirements.

The machine spirit was very excited to tell Ling Tian the news, and Ling Tian let out a long sigh of relief.

As long as it can be used, Ling Tian is now very glad that he had brought those two gates with him at that time.
