The appearance of the goblin airship convinced all the goblin warriors in the royal court, who originally had great respect for Li Yunfei, the equal king, and now almost treated him as a goblin ancestral god. [No pop-up novel network]

Li Yunfei was also honest and unkind, and began to continue the preparations in the Goblin Royal Court.

After the restoration of the goblin airship, he has made a major discovery. That is, the goblin airship was able to take off easily, not only because of the thrusters on it, but also because of the gold leaf attached to the metal skeleton

These gold foils are completely different from ordinary gold, and after Li Yunfei's test, they actually have anti-gravity properties, as long as they tear off a piece and throw it into the air, they can keep floating upwards until they reach an extremely high height, and the decomposition into fine particles disappears.

It can be said that after being covered with this metal foil, the weight of the goblin airship has been reduced by half, and it can be blown up by just a gust of wind, and with the thrusters, it can naturally rise into the air quickly.

This kind of metal can be said to be the most anti-heaven metal that Li Yunfei has ever seen, although it does not have the toughness of star iron and metal dragon skin, but this anti-gravity attribute can be called a miracle.

After Li Yunfei's research, he was shocked to find that this thing was not a natural metal, but was synthetically manufactured

Needless to say, this is the great legacy of the goblin civilization of antiquity.

Li Yunfei did not hesitate at all, directly gave up other work for the time being, and began to find all the abandoned goblin airship wreckage and began to search for the gold leaf on it.

Just as he was ecstatic and kept searching for gold leaf, Kidd personally came to the underground palace with a plate of food to visit Li Yunfei's work. Since the last time he flew into the air on the goblin airship, he had completely thrown himself into Li Yunfei's convincing five-body land. And he also found that this human boy definitely really understood the greatness of the goblin civilization.

"Thor, what are you going to do" Seeing Li Yunfei holding a magic crystal scraper and scraping off the gold leaf on the skeleton of the airship's wreckage, Kidd asked curiously.

Li Yunfei looked excited, his eyes were slightly red, and he said: "It's amazing that I want these metals, if I can think of a way to make them."

"Oh, you mean floating gold. Kidd said with a normal face, "Earlier, there are still a bunch of these things in the warehouse, and they are useless except for being able to make a few lighter armors."

As soon as he finished speaking, Li Yunfei had already grabbed his shoulder, and asked with a hungry face: "Where is this thing called floating gold?" The look on his face can only be described as hideous.

Kidd didn't expect Li Yunfei to react so violently, and immediately said: "It's in the secret vault in the back, and I also found it by accident, come with me." ”

Soon, the two of them came to the door of a secret vault on the back wall of the main hall, and the door slowly opened, revealing some metal ingots and ores inside. There are some metal ingots such as Mithril and Fire Copper that have been initially refined, but it is obviously just a warehouse for stacking materials, and the former goblins did not pay much attention to it.

It's just that these things didn't fall into Li Yunfei's eyes at all, and the first time he entered this warehouse, his attention was attracted by a golden metal ingot of dozens of cubic meters in the corner.

This huge metal ingot is golden in color, and it is completely a giant cube with a side length of eight meters. The huge metal cube did not sink deep into the ground, but instead levitated about a meter above the ground

Li Yunfei took a step forward, reached out and gently touched the huge metal ingot, which did not have the slightest weight at all, but floated directly up a few meters with his strength, and then fell into the air about one meter above the ground.

This thing is all floating gold, and this is also a characteristic of floating gold, that is, if there is no external force to push it, it will be suspended about a meter from the ground.

For Li Yunfei, the height of this meter is enough

He then leaped forward and punched the floating gold on the ground, trying to knock it to the ground.

At this time, he already had the body of a silver giant, coupled with the strength of his own fighting spirit, after mobilizing the strength of his whole body, it could only be described as amazing, and he could completely split the head of a black iron giant with one punch.

Listening to a loud "boom", a fist mark appeared on the surface of the floating gold, and the entire cube was a little flattened. Just looking closely, this huge piece of floating gold did not sink at all, and was still firmly suspended a meter above the ground.

Obviously, the anti-gravity attribute of this thing is extremely powerful, and under the anti-gravity attribute of such a large piece of floating gold, Li Yunfei's strength can't make it drop even a bit

"Hahaha, that's great" Li Yunfei laughed, ecstatic, he had been carrying out a secret plan for a long time, and at most he was only fifty percent sure, but now with these floating gold, he was at least eighty percent sure

Floating gold is a good thing, and it can definitely make some amazing things, and it is a terrible thing to use on a goblin airship. According to Li Yunfei's improvement, the goblin airship now does not need the anti-gravity force of floating gold at all, but can rise with just a simple thrust. A powerful metal like floating gold must be used in the most critical places.

"If my brother takes a fancy to this piece of iron, even if he takes it, it has been here for thousands of years anyway, and it is of no use at all. Goblin King Kidd said with a wave of his hand. The current goblin clan has completely lost the alchemy technology they once had, no matter how precious this piece of metal is, there is no way to use it at all, but it is better to let Li Yunfei take it away. Kidd's wishful thinking is that he has taken all such valuable metals, and it will be a little too much to say if he doesn't help the goblins

Li Yunfei was not polite at all, and with a flash of white light, he had already put this huge floating gold into the space ring, and then said with a sincere face: "Thank you, brother, this thing is very important to me." ”

Seeing that he could help Li Yunfei, Kidd was also very happy, nodded and said: "Since that's the case, then use it, you are the equal king of my goblin clan, who dares to disobey your order" After speaking, he squeezed his eyes.

Li Yunfei couldn't help but feel a warm current in his heart. The goblin king Kidd can be regarded as asking for him, but Kidd should also understand how difficult it is to revive a civilization, and Li Yunfei is likely to be gone forever. Still, Kidd was able to trust him so much, how could he not be moved. These goblins, who have lost their civilization, are much more civilized than civilized humans in terms of morality.

"By the way, Thor, I'm really confused, there's one more thing I should have given you a long time ago, I was so happy during this time that I forgot about it. Kidd patted his head, took out a book from his armor and held it to Li Yunfei.

Li Yunfei looked up and saw that the book was made of a piece of metal that was as soft as paper, extremely tough, and the cover of the book was a whole piece of water magic crystal plate, and the symbol of a gear was engraved on it.

Above the gear symbol are several large letters: Jade Record
