Seeing that most of the more than four hundred pieces of metal had been eliminated, even the only Elder Gru who had some confidence in Xiao Longchen began to shake his head in disappointment.

There is hardly anyone in the world who knows the most about the properties of metals as well as the Patriarch of Gelug. He knew very well the difficulty of smelting metal, so he was not optimistic about Xiao Longchen.

It's just that when he was researching the battle mecha before, he found that the metal used to make the shell of that thing seemed to be a little special, and even he couldn't tell what material it belonged to.

It was precisely because of this that he decided to give Xiao Longchen a chance to perform. It's just that the current facts show that his judgment seems to be wrong, and this little guy's ability is not as good as expected.

Therefore, after hearing the increasingly heated discussion among the clansmen, the Patriarch of Gru immediately prepared to speak out to stop Xiao Longchen in order to stop this farce.

No result, at least it can save some face for the little guy. If he really waited for him to look at the more than 400 pieces of metal again, and finally gave a fruitless ending, I am afraid that those clansmen who value faith more than life will do something out of the ordinary.

So the Gru patriarch spoke: "Longchen Xiaoyou, it is not so easy to create a new alloy, you have checked so many metals today, and the rest will be talked about later!"

Xiao Longchen was also a little surprised when he heard this, but before he could make a statement, Xiao Xing, who had been silent in his mind for a long time, finally reacted.

"Okay, Xiao Longchen, you don't need to check the metals in the back, I have calculated the three most suitable metals from the more than two hundred metals you checked in front of you. It is believed that the new alloy smelted can well solve the shortcomings of red fire gold essence with more flexibility and insufficient hardness. Xiaoxing's tone sounded very relaxed, as if he had done something insignificant.

When Xiao Longchen heard this, he immediately felt excited, so he looked at the Patriarch of Gru with a smile and said, "That's fine, it's really too much to check too much metal at once. Let's study the rest of them when we have time later!"

Seeing that Xiao Longchen knew each other like this, even if he still had a lot of complaints in his heart, Patriarch Gru nodded with satisfaction.

However, his generosity obviously could not represent the opinions of all the goblins present, and when he saw that the patriarch of the family had relieved this kid, the goblins who were waiting to see the excitement protested one after another.

"Patriarch, let him continue! Today I want to see if this little guy really has that ability, or if he can only speak as fast as he can!"

"Yes, Patriarch, I've been waiting for so long, and I don't care about waiting a little longer. Let him check the rest of the metal to see if he really has the strength of the goblin clan who despises us!"

"Can't you see it? This kid has been pretending all along, and I don't know where he learned a little bit about making that kind of mecha, and his tail is up to the sky!"

"Young people, you will inevitably be a little impulsive in doing things, and with this lesson, I believe that this little guy will learn to be humble in the future! We still don't want to be strong......

All kinds of voices of discussion came and went, which made the face of the Grew patriarch who played the round a little unpleasant. On the contrary, the smile on Xiao Longchen's face, who was the party concerned, remained unchanged until the discussion was over with self-righteousness, and he said lightly: "I think you may have misunderstood, I said that I won't study the remaining metals for the time being today because I have found the three I need, and you haven't waited for me to announce the results, just talk nonsense here, isn't it fun?"

Xiao Longchen's words made the smug expressions of those goblins who had felt raised their eyebrows a moment ago instantly solidify on their faces, and even the Gru Patriarch showed a look of shock.

He first cast an inquiring glance at Xiao Longchen, and seeing that he didn't say anything more, he asked with some uncertainty: "This kind of thing is not a joke, you just said that there is already a result, did you really find a metal that can be fused with the Red Fire Gold Essence?"

Xiao Longchen didn't answer his words directly, but under Xiao Xing's guidance, he picked out three pieces from the large pile of metal, handed them to the Patriarch of Gru, and swore an oath: "Whether it's true or not, you'll know if it's a try!"

The Patriarch of Gru took the three pieces of metal with some uncertainty, but after a glance, he recognized that these three pieces were just ordinary metals, and their value could not be compared to the Red Fire Gold Essence at all.

But since Xiao Longchen is so calm and calm, he can't say anything more. Instead, he took out a piece of red fire gold essence from the ground again, held it in his arms along with the three pieces of metal, and walked towards the furnace that exuded a scorching heat not far away.

After throwing all four pieces of metal into the Dao furnace, the Gru patriarch carefully observed the changes in several metals.

And the goblins who were still talking cool just now all turned red. The words that sarcastically mocked Xiao Longchen just now turned into a slap in their face in the blink of an eye, and this kind of thing is a little uncomfortable for anyone.

"Smelting four metals at once, not even our goblin clan has such a precedent!"

"I think that little guy is just a little annoyed and angry by what we said, and wants to use this kind of grandstanding to save some face, and he hasn't found a way to smelt a new alloy at all!"

"Yes, when the results come out later, let's see what else he has to say!"

The group of goblins were obviously unwilling to be slapped in the face by a human teenager, and although the voice of the discussion was much quieter at the moment, they still didn't want to believe that Xiao Longchen could do something that even their goblin clan couldn't do.

As time passed, the four pieces of metal in the furnace began to melt at high temperatures. Originally, there was a kind of Xingchen Steel with different properties, and there was even a kind of Xingchen Steel that was repulsive to the Red Fire Gold Essence, but all of them began to slowly merge under the neutralization of the other two metal melts.

As a result, the goblins who had never been willing to believe in Xiao Longchen's ability changed their faces in unison.

It is important to know that many metals are repulsive due to their properties, and even if they are fired into liquids, they cannot be fused into one at all.

The kind of metal called Xingchen Steel, because of its extremely strong hardness, there were ancestors of the goblin clan who tried to use it to fuse it with the Red Fire Gold Essence, but after smelting the two together, the finished product was entangled with each other like a twist, and it could not be fused at all.

The fusion they saw at this moment showed no signs of mutual exclusion at all, which meant that even if the performance of the smelted metal was not as good as that of the Red Fire Gold Essence, it was indeed a new type of alloy!

This time, all the goblins closed their mouths, and even the eyes of the Gru patriarch began to brighten.

Among the people present, when it comes to understanding the properties of metals, there is no one who can compare with him. Before seeing the results, he only thought that the properties of these metals did have the possibility of complementarity. But after seeing the perfect fusion of these four metals, he couldn't help but silently deduce the properties of the fusion in his heart.

The end result is undoubtedly a wonderful match that makes him feel bright.

Star Steel is known as the hardest metal, and although its hardness is the best of all metals, weapons or armor made purely from this metal are a bit too rigid and easy to break, and they can't be compared to Red Fire Gold Essence.

The other two metals, Mithril, have very good conductivity and can absorb the energy impact to a large extent, so it is also an indispensable material for making star weapons in the human world.

As for the last metal, it is the most common black iron, which can be said to be the most widely used material, because it has the highest yield and the performance is quite modest, and many utensils in daily life are made of black iron.

Before today, when the goblin ancestors studied the Red Fire Gold Essence Alloy, they did not even think of adding black iron, an extremely common intermediate material.

I didn't expect that today's seemingly out of tune behavior of this human teenager could really make those four metals fuse perfectly. Regardless of the final experimental results, at least in the smelting step, it proved that Xiao Longchen's plan was feasible.

Patriarch Gru suddenly looked forward to it, if this human boy could really have this kind of knowledge, then the Haikou he boasted about before would not be an insult to their goblin clan.
