Lu Chen hit a Ji Ling, he speculated that this was because he absorbed too much negative energy, so he himself was insidious. He hurriedly stopped absorbing negative energy, but kept stimulating his own negative energy, hoping to solve the sequelae of absorbing negative energy.

In the next few days, Lu Chen did not remove the negative energy for the giants. Or under the leadership of the giant stone, walk around in the tribe of the giant tribe. Either just meditate and practice alone, or take out the Zhenlong pile to get familiar with it.

On this day, he reached a special place on the shoulders of the boulder. Here the underground fire rises, burning the void to be distorted. Above the ground fire, there is a huge cauldron. There are several stone platforms beside them, and a few table-sized hammers beside the stone platforms are particularly eye-catching.

"Boulder, where is this place, why does it look so weird?"

"My lord, this is the place where my giant clan used to refine tools."

"Oh, the giants still know how to refine tools?"

"Of course, our giants are the best craftsmen in the world. Many peerless gods come from the giants. But later, the giants were troubled by the divine punishment, and it has been a long, long time since no one is crafting. My lord, if I If you are not mistaken, there is a treasure in your hand that is the Dragon Stake, in fact, it was created by our giants."

"What, the Zhenlong pile was made by the giants?"

Ju Shi nodded, with a proud look on his face, and said: "At the beginning, the ancestors of our giants were preparing to build an ultimate weapon, and the dragon-suppressing pile was only a part of it. But ten thousand years of things completely let their plan. Miscarriage. All parts of the ultimate weapon are also lost."

"This……"

Lu Chen no longer knows how to describe his current mood. In his mind, Zhenlong pile is already very, very powerful. But this is actually only a part of the ultimate weapon, he can hardly imagine, once the giants create the ultimate weapon, it will be against the sky.

"My lord, now our giants are gradually returning to normal with your help. Therefore, I plan to gather the power of the whole clan to build a weapon tailored for you."

"Build a weapon for me?"

Lu Chen was taken aback, and then understood that the reason why Ju Shi brought him here was to build weapons for him. Ju Shi looked at him and said, "My lord, what kind of weapon do you want, as long as you tell it, we will do our best to build it for you."

"sword!"

Lu Chen wanted a sword most when it was a weapon made by medicine. What he is best at is swordsmanship. Although the dragon-suppressing pile is powerful, he still likes to use swords. Suddenly, he thought of the aquamarine iron he had obtained in the Black Sea, and his heart throbbed. You know, Xingchuan aquamarine iron is the best material for building weapons. If you use it to build a sword, what will it look like?

Lu Chen took out the Star Azurite Crystal Iron from the Space Ring. Seeing such a large piece of Star Azurite Crystal Iron, the eyes of the huge stone were also wide as lanterns. Obviously, he was also taken aback. Lu Chen smiled and said, "How about using it to build a sword?"

"Lord such a piece of sapphire blue crystal iron, not to mention to build a sword, even if it is enough to build ten handles. But... it is a waste to build a sword for adults. If it is used to build a tripod, it may be more powerful, you Look……"

Lu Chen shook his head and said, "Sword, my favorite weapon is the sword."

"My lord, don't worry, I will create a wonderful sword for you!"

"I'm waiting!" Lu Chen's eyes showed expectation. He couldn't wait to see what the giants, who are best at building weapons, would look like a peerless sword tailored for him!

It's done!

In another five days, the negative energy of everyone in the giant clan was completely swallowed by him, and the hostility in the dantian nearly doubled.

In the past few days, the giants are going in and out up and down, seeming extremely busy. Lu Chen knew that they were preparing to build a peerless sword for himself. Although the main material, Xingchuan Kyanite, was already available, many other auxiliary materials were needed.

For the entire giant clan, Lu Chen is equivalent to recreating them. Everyone was grateful and wished to do more for him. Now they were going to build a weapon for him, and they worked hard one by one, preparing to build a wonderful sword for Lu Chen.

Lu Chen knew the thoughts of these people, but he didn't stop it. Now these people are suffocating in their hearts, if they don't let them do something for him, maybe something will happen. During this period of time, in addition to preparing various sword-making materials, the giants also practiced refining tools. Although their ancestors are the most powerful refining clan in the mainland, they also have various refining documents, but they have no refining tools for thousands or even tens of thousands of years. Therefore, they must practice to transform the talents in their bloodlines. For strength.

Lu Chen would occasionally visit the refinery room. Although these people were still beginners and very powerful, the weapons they crafted were very exquisite. If any item is brought to the market, it will attract many people to **** it.

On this day, Lu Chen was free, lying on a rock, wandering beyond the sky. He did feel a little bored these two days, and the days without goals made him a little listless. Suddenly, Lu Chen sat up from the rock. He didn't want to continue like this. He needed something to do for himself.

Holy liquid!

Lu Chen thought fiercely that his other goals in the black prison had been completed, but his biggest goal had yet to have a clue. Suddenly, Lu Chen slapped his thigh fiercely, and said, "The giants have lived in the black prison for so long. They should know the black prison very well. I can ask them where there is holy liquid in the black prison."

Lu Chen couldn't wait to come to the refining room, pulled the boulder out of it, and said, "Boulder, do you know where there is holy liquid in the black prison?"

"Holy liquid? What is that?"

Seeing the giant stone, he didn't know, Lu Chen's face showed a deep disappointment. For not helping Lu Chen, Ju Shi also apologized and said, "My lord, I couldn't... By the way, after our ancestors came here, they left a lot of documents. We may be able to find some clues."

After speaking, the giant stone took Lu Chen to the place where the giants specialize in storing books. In the past, when the giants were not bothered by the curse, they did a good job in all aspects. Even afterwards, these things were not destroyed because of the negative energy in the heart. Soon, the two came to a huge space, which was as huge as the refining room. There were many stone bookshelves and many books on the bookshelves. Lu Chen roughly estimated that there are at least 100,000 books here.

After approaching and browsing the entire room, he found that the ancestors of the Giants actually had classifications for these books, including history, geography, refining, medicine, and so on. The various categories add up to dozens of categories, and she has never heard of many categories.

Now Lu Chen really believes that the giants were once one of the rulers of the mainland. Even if they have not fallen to this point, the documents are so well preserved, this is definitely not owned by ordinary forces. And this is the bottom line!

Immediately, the two got a headache. Among so many books, even if the books are classified, finding the information of the holy liquid is like finding a needle in a haystack. First of all, Lu Chen chose elixir books. There were a lot of elixir books, occupying at least one-tenth of the book collection. In other words, if there are 100,000 books here, then there are 10,000 books about elixir. But in order to be able to find the clue of the holy liquid, Lu Chen bit his head and looked at it.

Huhu!

He just hadn't read five books, and there were snoring sounds next to him. Turning his head, he saw that the giant stone was asleep with a book in his hand, leaning against the bookshelf, and saliva flowed from the corner of his mouth, pulling up a long water line. Lu Chen didn't wake him up, and it was absolutely no problem to let the boulders beat and kill. It was too embarrassing for him to read the book.

Therefore, Lu Chen browsed again and read hundreds of books, but still did not find any information about the holy liquid. Putting a book back on the shelf, Lu Chen said to himself: "Holy liquid is not a panacea, maybe I am looking for the wrong direction."

After a moment of hesitation, he walked towards the other bookshelf. When he came to the bookshelf of the refining device, he immediately skipped it. The holy liquid was not the material of the refining device. He also skipped the history books, and after a while, he came to a bookshelf. This bookshelf was for geography, but the label on it made him a little confused.

Under curiosity, he took the book and looked at it. He didn't know it, and his face quickly showed a surprise. Because the content of these books is actually a geographical introduction to the black prison. On the map, he found Broken Mountain and several places he had visited before.

After a while, Lu Chen's face showed a look of surprise, because the black area was so big, it was many times bigger than the black area he had imagined. Even the land area of ​​the dynasty is not necessarily as large as the black prison. He also noticed that there were several red lines on the map, dividing the map into seven parts. In each part, the blue line divides it into many small parts.

Lu Chen couldn't understand what the thin red and blue lines represented. After reading the map carefully, he picked up a thick book from the side. The book contains a detailed explanation of the geography of Hell. Suddenly, Lu Chen was like a treasure. This book was actually a detailed explanation of the geography of the black region. With the addition of the map next to it, he could know the entire black region well.

Wow! Wow! Wow!

In the whole room, only the sound of Lu Chen flipping through the book was heard, and he looked very carefully. The more shocked he looked at his face, he didn't think that the black prison was actually possessed. The red line divides the black prison into seven parts, which are controlled by the seven ancient families. And the blue line in it is divided into many pieces, each piece represents a dynasty. There are many barriers in the black prison, which isolate the various dynasties. People of each dynasty can only move on their own territory, and basically cannot go to other realms.

"found it!"

Suddenly, Lu Chen's eyes were as bright as lanterns, and he found news about the holy liquid. The holy liquid is a special substance in the black prison, and every dynasty has the holy liquid in the black prison. Under normal circumstances, there is only one place in the boundary of each dynasty that can give birth to holy liquid.

"There is only one place!" Lu Chen's expression changed. The sacred liquid in the area they were in had already been obtained by Xing Wu. Unfortunately, this guy didn't know how to keep it and directly contaminated the sacred liquid. In other words, there is no holy liquid in the black prison where they are now.

"Damn it!"

Thinking that the only holy liquid had been destroyed by Xing Wu, Lu Chen really wished to thwart this guy. Unfortunately, he didn't know that Xing Wu only destroyed a drop of holy liquid, but he himself absorbed a whole pond of holy liquid. If he knew it, he didn't know what it would look like.
