Soon, they had come to a huge underground hall. [Full text reading]

Thick pillars are arranged in this hall, and there are almost a thousand. The area of this hall is also the size of several football fields, which makes people marvel at the grandeur of this underground project.

Li Yunfei looked up and saw that the surrounding walls were full of gear patterns, giving people an exotic feeling.

At the same time, the open space of this hall is full of rows of metal supports, on which are placed all kinds of things.

Some of the stands also have crystal cabinets on top of them, and some beautifully shaped machinery are placed inside.

The furnishings here reminded Li Yunfei of the goblin ruins he found in the Steel Soul Half-Plane, but the scale was many times larger.

The moment he saw these things, Li Yunfei's eyes lit up, Rao had gone through the experience of the corpse mountain and the sea of blood, and he couldn't help but get excited at this time.

Needless to say, the things placed here are all creations of the once powerful goblin civilization, and they are probably all alchemical items!

"This is the great power of the ancestral gods, all of which used to be the pride of our goblins. Speaking of this, the goblin king lost his mind slightly, and seemed to think of something, "Humans, do you know, the ancestors of the goblins once ruled the entire world for tens of thousands of years, and at that time, all races were subjugated to us, but then a huge catastrophe occurred, and the ancestors completely lost their power and were forced to live on this wasteland??"

A wry smile appeared on the goblin king's face: "We goblins, we can't even use the tools left by the ancestors, let alone make any of them, and when the last batch of ancestral relics is completely unusable, the goblins may become beasts completely." ”

"I'm ashamed to say that although I am the king here, I am still just the leader of a pack of beasts?? The vast majority of things here are no longer usable, and you can see if it helps you, just take it. ”

Hearing this, Li Yunfei nodded, and a trace of compassion appeared on his face.

Although I don't believe that goblins were once powerful enough to rule the world, this civilization is definitely a once brilliant existence, but I didn't expect it to fall into the current field.

It's just pity for mercy, after getting the master's consent, he immediately jumped into the countless relics of civilization, and began to carefully observe and study, tweeting that during this time, under the teaching of Li Yunfei, he also had a certain understanding of alchemy, and he also saw the joy of hunting, and began to pick it up and study it one by one.

You must know that this is a relic of a top-level alchemy civilization that once existed, and the huge value contained in it is needless to say.

Oval crystal vessels the size of a football ball are placed there, and the interior is filled with various kinds of filling, which looks very beautiful. Li Yunfei picked it up casually, first put one of them into the space ring, and then picked up one again, directly used brute force on his hand, violently dismantled it, and began to carefully study the structure in it.

This crystal vessel is the goblin bomb used by the Goblin King!

After only looking at it for a short while, Li Yunfei already understood that the structure of the goblin bomb was to engrave complex magic circles on two metal discs, and then use more than a dozen small magic crystals and two large magic crystals to set up two corresponding alchemy circuits, and cause violent explosions through energy hedging.

It stands to reason that even if the energy of these magic crystals is released all at once, it is not so powerful, obviously after the addition of the alchemy array, and the energy level has doubled after bombarding each other.

It's just that this goblin bomb is obviously unable to detonate, and the luster inside has dimmed a lot. A closer look reveals that many of the metal circuits wrapped inside the goblin bomb have decayed, and the magic crystals used in the goblin bomb have dimmed and seem to have lost their energy.

Li Yunfei secretly admired the exquisite structure of this goblin bomb while inspecting the metal used in the two array disks.

The high level of alchemy allowed him to immediately understand the metal structure contained in it, but then he couldn't help but marvel.

The metals used in this array are all alloys, and there are more than a dozen kinds of precious metals doped in them, and there is even a kind of divine material, although the content is relatively small, it still belongs to the divine material.

These goblins are simply losers! Li Yunfei rolled his eyes. The precious materials used in this goblin bomb are comparable to a magic cannon, if not surpassed.

This thing is a completely one-time consumable item, and it is gone when it runs out......

This also shows how powerful the goblin civilization was in the past.

Thinking of this, Li Yunfei casually put the disassembled goblin bomb into the space ring. Although the cost is too much to lose, the production of this goblin bomb is ingenious, and when you have time later, you can see if you can use some cheap materials as a substitute to make it.

Immediately afterwards, Li Yunfei continued to study all the way, and the more he watched, the more amazed and excited he became.

There are not only goblin airships that have been seen before, but also something similar to a one-man glider, and it is equipped with thrusters, which is completely a small aircraft. In addition, there are also some small magic cannons, which vaguely resemble the prototype of the magic gold war gun in terms of production concept. All kinds of construction machinery, some alchemy items for lighting, cooking, etc., etc., etc., can be said to have everything.

Through these alchemy equipment, a powerful technological civilization that has infiltrated alchemy into all areas of social life has appeared in front of Li Yunfei.

You must know that those alchemy equipment that is not used for military purposes, but for life purposes, is evidence of a powerful technological civilization, just like the earth civilization in Li Yunfei's previous life. It's just that the earth civilization uses science as the basis for building society, and the goblin civilization uses alchemy as the basis for building society!

Among these alchemy equipment, many coincide with the ideas of earth technology that Li Yunfei understands, many of which Li Yunfei also conceived, but he didn't have time to make them, and some of them were beyond Li Yunfei's imagination, which made people have to marvel at their ingenuity.

A few hours later, Li Yunfei had already checked all the alchemy items in the entire hall, but what disappointed him was that although these things were all extremely exquisite, the items related to leaving here and returning to the human territory did not appear, and it did not help his ultimate purpose.

Li Yunfei shook his head slightly, frowned slightly, and looked up at the goblin king who was on the side.

Just as he was about to speak, a terrible howl suddenly came: "Report to the king, the demon has appeared! The demon has appeared! There are more than a thousand in total, and there are thirteen white demons!"

Hearing this, the face of the goblin king, who was originally smiling, instantly turned pale, and then he looked at the entrance of the underground palace, and did not respond to the sentry above, but put on armor and turned around and ran towards the depths of the main hall!
