Xiao Longchen seemed to have thought of something, and suddenly his eyes lit up, and he asked in his mind: "Xiaoxing, as far as I know, most of the more practical metals on the earth are alloys, if you bring other kinds of metals in this world, can you analyze which ones can be fused with the Red Fire Gold Essence and improve its performance to a higher level?"

"Yes!" Xiaoxing's answer to what he is sure of is always so crisp and neat.

Hearing Xiao Xing's affirmative reply, Xiao Longchen suddenly became excited. The forging technique of the Gru Patriarch is already the strongest among the goblins, and if you want to make the shell of the battle suit mecha stronger, you can only find a breakthrough in the material.

Thinking of the battle suit mecha produced by their Long family, Xiao Longchen instantly thought of the special material of alloy.

Every metal has special properties. When people make weapons and equipment, they generally choose different metals according to different needs.

However, with the continuous development of scientific and technological civilization, people's demand for materials has become more and more demanding, so in the absence of a better alternative, they can only create new metal materials through fusion.

In fact, as early as thousands of years ago, the ancestors of the Spring and Autumn Period and the Warring States Period had already invented alloy materials.

They fused metal elements such as brass and tin to create bronze, a metal that was easier to cast, and left a strong mark on Chinese history.

On the earth in the 23rd century, almost all metal products can be seen in life, and their materials are all alloys.

Xiao Longchen had also studied alloy knowledge in class, so he knew very well that the new materials smelted by this special process far surpassed those ordinary metals in terms of performance.

"Patriarch Gru, can you take some samples of all the metals that exist in your goblin clan?" Xiao Longchen made up his mind, and he would not hesitate any longer, and immediately made his request to Patriarch Gru.

"Little friend Longchen, this red fire gold essence is definitely the best material for creating the shell of the battle suit mecha, no one can understand the characteristics of various metals better than me, so you don't need to waste your efforts in terms of materials!" Patriarch Gru frowned slightly, obviously this time it was really because of Xiao Longchen's distrust of him, and there was a trace of disgust.

Xiao Longchen saw the gentle smile on Patriarch Gru's face disappear, and knew that the other party might have misunderstood what he meant, so he hurriedly explained: "Patriarch Gru, you may have misunderstood, the reason why I want to study other metals is not because I don't trust your understanding of the characteristics of metals, but because I want to see if any of those other metals can be fused with the Red Fire Gold Essence to improve its performance!"

Patriarch Gru was shocked when he heard this, and he was immediately impressed by Xiao Longchen.

Their goblin clan has been dealing with metals for tens of thousands of years, and they are naturally no strangers to alloys, but almost all of the alloy formulas they have mastered now have been made by their predecessors by accident.

The technology in this world is almost zero, and the goblins don't know what the periodic table is, and the knowledge and skills that have been passed down are all gathered by the experience of their predecessors. Therefore, although the forging technology of the goblin clan is exquisite, it is much behind the earth in terms of material science.

"Xiaoyou Longchen, this method of smelting alloys has also been studied by our goblin clan, but the Red Fire Gold Essence is already a very perfect precious metal, even if it is fused with other metals, it is impossible to improve its performance by any more. Patriarch Gru said politely, but in fact, he already had some opinions about Xiao Longchen in his heart.

In his knowledge, no one was more experienced than their goblin clan when it came to metals and forging. This human boy is mysterious, but he doesn't want to point fingers in what they are good at.

This is the faith and dignity of their goblin clan, which no one can infringe on!

Xiao Longchen saw that the attitude of the Patriarch of Gru suddenly became indifferent, and even the group of forging masters who were watching the excitement on the side were staring at him unkindly, and Xiao Longchen suddenly felt a little furious in his heart.

"Xiao Xing, are you really sure that you can help me make a new alloy?" Xiao Longchen confirmed with Xiao Xing again for the sake of insurance.

"I'm not sure, but as long as there are metals that meet the criteria, I'll be able to analyze them. Xiao Xing's answer not only did not make Xiao Longchen feel at ease, but also pushed him into a dilemma.

He lowered his head and pondered for a moment before asking tentatively, "Patriarch Gru, how many metals are in your vault?"

Although the Patriarch Gru didn't know why Xiao Longchen asked this, he still replied with a proud face: "For tens of thousands of years, our goblin clan has never stopped searching for and digging metals, and today, there are more than 400 kinds of metals in the treasury. Among them, the properties of most metals have been thoroughly studied by us, and only the last three metals are still unclear what they can be used for!"

As soon as Xiao Longchen heard the number of more than four hundred, his eyes suddenly widened. Even if you are mentally prepared, you still underestimate the degree of perversion of this world.

However, the more types of metal, the greater the chance of success, and he has no intention of competing with the goblins, just to make the battle mecha he creates more powerful.

Xiao Longchen had already made up his mind at this moment, even if it would damage the friendship between him and the goblin clan, it was still worth the risk.

After all, after seeing those powerful beasts in this world, no matter how strong the defense of the battlesuit mecha is, Xiao Longchen doesn't feel enough.

"Patriarch Gru, there is an old saying in my hometown, called 'stones from other mountains can attack jade', and the ability and talent of your goblin clan in forging are naturally beyond our human race. It's just that in terms of material research, my hometown doesn't seem to be worse than the nobility, I hope you can understand my offense and give me a chance to try!"

As Xiao Longchen spoke, he bowed deeply to the Patriarch of Gru, his upper body was level with his waist and limbs, at a ninety-degree angle, obviously full of sincerity, which made Patriarch Gru's face soften slightly.

Even the goblins who were eyeing him on the side were a little less hostile to him.

The Gru patriarch first glanced at the battle-suited mecha standing quietly not far away, obviously believing Xiao Longchen's words, so he directly ordered to go down, and soon hundreds of sturdy goblins, each carrying a piece of metal, sent over.

The metals are of different colors and materials, but their shapes are almost identical, and they are all cast in a mold.

Xiao Longchen looked at the large metal ingots densely packed in front of him, and couldn't help but feel a little uncertain about Xiao Xing's ability.

"Little friend Longchen, these are samples of all kinds of metals of our goblin clan, you can pick out the ones that you think can be synthesized with the Red Fire Gold Essence, and I will personally help you smelt and experiment later, I hope you don't disappoint me!" Patriarch Gru's words made people feel inaudible, the first half seemed to be very confident in him, but the last sentence that seemed to be a warning made Xiao Longchen feel a little uneasy.

Although if the attempt fails, the Gru patriarch should not do anything to him, but the group of dwarfs on the side may not be able to tell.

"Haha, Patriarch Gru laughed, since I made this request, it means that there is still some certainty, you let me take a closer look. Xiao Longchen said, and began to pick up the metal on the ground to "study", and his mind was always paying attention to Xiao Xing's reaction.

As Xiao Longchen looked at the pieces of metal, his face became more and more difficult to look at, because the little star in his mind had not spoken, so he could only continue to search.

Seeing that most of the metal had been checked, the surrounding blacksmiths began to talk about it.

"Human astrologers are indeed powerful, but it's a joke to compare to us goblins in terms of metal forging and smelting!"

"Yes, if this kid can't find a metal that can be fused with the Red Fire Gold Essence, we must teach him a lesson, and let this little guy know the fate of despising our goblin clan!"
