After all, the infrastructure of the underworld, such as the blood pool, is something that lives on its own, although it says that it wants to destroy it. But this is just talk, if it is really put into action, unless Lin Jun's head is amused......

The change continued, and I saw a complicated text appear above the pool of blood. If it is tantamount to a book from heaven to ordinary people, but for Lin Jun, who can gain something in order to be able to enter those tombs, he has done in-depth research on the languages of various races. There is a saying that goes like this: "If you want to go deep into a country, you must first understand their history." ”

And the most important history of a country is tantamount to the writing that belongs to their country! Because with writing, a civilization system can appear! Only then can civilization be developed, so Lin Jun, who understands this, has some understanding of the writing, history, and civilization of various races, of course, Lin Jun does not mean that he understands the civilization of all races, at least for now, Lin Jun does not know anything about civilizations such as orcs and goblins.

Of course, Lin Jun didn't plan to understand the civilization of the half-orcs, after all, the half-orcs can't even talk about having civilization now! But for the glorious history of the goblin clan, Lin Jun is very interested, but the records about this can be said to be vague, and there is no information to be used at all, for example, it is recorded in the book that the goblin technology civilization is very strong, but the records about this can be said to be very few! As for the others, there are almost no records.

This made Lin Jun, who listened to the story of the powerful goblin technology civilization, very itchy, the original goblin clan and the dwarf clan relied on alchemy engineering to create a god-level combat individual, so what are the materials and processes required to make zuò?

Even if this dynasty is destroyed by the gods, then it will inevitably leave information about this! After all, if they can create a god-level combat individual, they must also be able to think of leaving information about this for their descendants. If you can get the information of the goblin technology civilization, then even if you can't create a god-level combat individual, you can still learn from their ideas and create your own system, right?

After all, he can be described as a rookie among rookies in this aspect of alchemy engineering, although it is said to be a rough peep, but it is just a tricky way to get it, it is really not elegant, and it is not worth taking out.

Returning to the topic, I saw a complicated text appear above the blood pool. Others may not be able to understand it, but Lin Jun immediately recognized that these words were the ancient undead scripts!

The general meaning of these ancient undead texts is: "When the earth feels the power of the blood pool again, it is the time when the spirit of the earth recovers!"

"Earth Spirit, what does Earth Spirit mean?" Seeing the words floating above the blood pool, Lin Jun couldn't help but have this question in his mind? There was no such thing in the underworld at the beginning! Even Lin Jun only inadvertently promoted a 'Lich Research Institute' at the beginning, and only then did he understand that these buildings in the underworld could be upgraded! However, when the 'Lich Research Institute' was upgraded, there didn't seem to be any reaction. Well, it seems like I only found out about it after the fact. Maybe you missed it......

Let's not talk about these things for the time being, let's talk about the upgrade first. The benefits of upgrading are self-evident, after the original 'Lich Research Institute' was advanced, it was orderly that all skeleton wizards of any level as long as they had contact with the side hustle had their skills in this aspect increased by one level!

I remember that it was that time that my strength improved by leaps and bounds! After all, the things that the 'Lich Research Institute' studied were naturally not things that saved people, but those powerful lethal weapons and skills...... Therefore, strong productivity brings more powerful combat effectiveness!

Although I don't know what the spirit of the earth means, the change of the blood pool continues, and a tall pillar similar to a Huabiao appears at a great distance from the blood pool! I saw that there are frost dragons spitting cold flames carved on it! The feeling of coming out is as if there really is a group of frost dragons in front of your eyes!

Although the frost dragon depicted on it was hundreds of thousands of times smaller, that vivid appearance couldn't help but remind Lin Jun of his combat partner 'Xiaoice'......Xiaoice!

"Oh~ I really miss those guys! I don't know how they're doing now. Will it be bullied by those players?, they must be very sad that I suddenly disappeared!Hmph, the group of fools ...... "I can say that if I still have any nostalgia for the original world, except for my dead parents, there will only be those guys who accompany me in the north and south."

"Don't mention it, if you have the chance, bring them over!" This is the deepest thought in Lin Jun's heart, although Lin Jun knows that this kind of thought seems very naïve, but Lin Jun believes that he will be able to meet them one day! Even if it is a dream, Lin Jun does not want to shatter them!

After thinking about it, he still didn't know the meaning of the Earth Spirit, but Lin Jun quickly put this question aside, Lin Jun knew that even if he was thinking about the answer, he wouldn't pop up, so it was better to put them aside first! When he found it, he would naturally be able to understand......

A guy riding on a frost dragon was carved on the pillars similar to Huabiao, and Lin Jun took a closer look at this person who was exactly like himself! Lin Jun was really amazed by the ability of the Dark Book! There were a total of sixteen pillars similar to Huabiao standing around the blood pool at a certain distance!

Then I saw that the blood pool also began to change, only to see that the outermost part of the blood pool was light red, and then the more you went into the blood pool, the redder the color became, and even the innermost color became black! But the black part was tight, and it was obvious that the blood of this orc chief could only provide this trace of energy!

But just like that, Lin Jun was very satisfied, after all, it was already beyond his expectation that the blood pool could be advanced! Although Lin Jun also had a trace of expectation at the beginning, Lin Jun only thought that it should only be able to improve, so when he was waiting, Lin Jun thought that there was no play! But happiness always came so suddenly! The change in the blood pool really made him too excited!

After all, with the beginning, you will naturally be able to find a way to improve the blood pool! As long as you find more powerful blood, you will naturally be able to increase the energy of the blood pool, and there will naturally be only this trace of black in the future!

Finally, I beg for some collection support!
