In the room, Edward looked at Yang Hao's confident eyes, finally calmed down his tense nerves, and gave Yang Hao the bottom again.

After 20 minutes, Yang Hao broke away from the state of thinking and said, "Now it is clear that the conspiracy of the gray dwarves has reached the last moment, and the change in their attitudes before and after is the best proof of this." ”

"That's right, I've seen that copper hammer several times before, and every time it's polite, it's as rough and brutal as today." Edward chimed in.

"By the way, who did you sell your weapons to?" If the gray dwarf wants to do something to humans, it is naturally impossible for the enemy, so what is the problem with the weapon.

"Sold to other big nobles and the army, after all, my family's weapons are not cheap. How? Do you suspect that there is a problem with the weapon? Impossible, my family has been in the weapons business for decades, even if the craftsmanship is lost, this vision is still good, and the quality of the weapon is definitely certified! Edward said proudly.

Although he kept saying that he wanted to break away from the family and forget about the family, Edward, who had been instilled with the idea of loyalty to the family since childhood, still valued the glory of the family very much.

"It may be some kind of witchcraft, and Saron's purpose in asking for human slaves is definitely not as simple as he claims. He said that he wanted slaves to do technical work, but almost all of them had a talent far beyond ordinary people, and it stands to reason that as long as the slaves liberated the gray dwarves from simple work, their work efficiency and innovation ability would be greatly improved.

These manual work gnolls are enough, and they are good to feed.

Saron wants humans to definitely not let them work, is it... Edward, stay well, I'll go to the library. ”

Yang Hao left Edward behind without a tail, handed over the gray dwarf warrior at the door, and asked to go to the library.

The gray dwarf warrior guarding did not embarrass Yang Hao, and took Yang Hao to the library by dividing one person.

"Human, I'll stay at the exit and don't try to go where you shouldn't." The gray dwarf warrior warned Yang Hao and turned into a statue again.

"Hehe, don't worry, I'll stay here all night and won't go anywhere." After Yang Hao finished speaking, he pushed the door and walked into the library.

The reason why the stacks are called stacks, not libraries, is that most of the books here are packed in boxes, and there is a lot of dust on the boxes, and it is clear that no one has opened them for a few days.

Of course, there are books on normal shelves, but just three bookshelves are negligible compared to these hundreds of boxes.

The books on the shelves were not dusted, and Yang Hao glanced at them and found that they were all books about iron smelting and life, which were of little use to Yang Hao.

As for why Yang Hao can understand the words of the gray dwarf, this is actually one of Yang Hao's preparations for this trip.

At that time, when he got the power of the earth witchcraft scroll, Yang Hao had a hunch that he would have an intersection with the gray dwarf text, so he invested 30 idle knowledge points and initially learned the gray dwarf script.

This level of learning can only allow the system to help Yang Hao translate the gray dwarf text roughly, similar to machine translation, and the translation of grammar, allusions and everything is very stiff, but it is enough for Yang Hao to distinguish the general content of a book.

Yang Hao came here to obtain research materials related to the power of the earth, although there are many boxes here, but the books in them are also placed in different categories, and there are very few books on witchcraft and occultism, so he is looking for books very quickly, opening the box, taking two books and flipping through them, it is not a direct pass of the occult.

Finally, two hours later, after rummaging through about two hundred boxes, Yang Hao got what he wanted - a full 6 handwritten experimental notes in Madrid.

This is also the only book on occult knowledge that Yang Hao has found, and the gray dwarves don't seem to pay much attention to their elevator technology, but they are cheaper than Yang Hao.

Flipping through a notebook, Yang Hao looked at it at a glance, and after a while, he exhaled a breath of turbidity, and finally understood why this so-called power of the earth was not treated by the gray dwarves.

This Madrid is simply a master of bringing witchcraft to life, and looking at his conjectures in his notes, he has all been introduced to life by the use of the power of the earth, and he even proposes a setting similar to that of a hovercar.

To put it simply, he is a genius with a little crooked talent.

However, Yang Hao didn't want ready-made witchcraft, but wanted to master the method of manipulating gravity with magic like Sonic Wave, which was the most fundamental.

After hastily flipping through it, Yang Hao put these 6 notebooks into his backpack preciously, and now he has another thing to do - find Brother Gao Leng.

The lava crypt is very close to Brother Gao Leng's original route, and since his disappearance is related to the gray dwarf, then the eight achievements are trapped in the lava crypt.

Before coming, Yang Hao judged through Edward's description of Saron that his sorcery strength was comparable to that of players like them, and he had not reached the apprentice level, and most of his abilities were playing with insects, so it was impossible for him to control Brother Gao Leng, who was proficient in the shadow system, that is to say, there was an apprentice-level wizard unknown to Yang Hao among the gray dwarves.

It feels very bad to face the unknown, especially in the face of unknown enemies, but in the absence of Brother Gao Leng, the demon hunting group has always been in a state of dissatisfaction, which Yang Hao absolutely cannot tolerate.

There is only one exit from the library, so Yang Hao can't go through the door, and although the guy on guard hasn't come in for two hours to see, he will be suspicious if he can't hear movement for a long time.

However, this is not difficult for our brother Hao, the dungeon where Gao Leng is most likely to be imprisoned is located at the lowest level of the crypt, close to the minerals of lava steel, and there is a team (12 people) of gray dwarves guarding each floor of the elevator, so taking the elevator down is a dead end.

Yang Hao's plan was to find a hidden place to dig down, and his ultrasonic detection could easily find the cracks between the soil and rocks, and shake them to be soft and abnormal, so it was not difficult for him.

It would be easier to create movement, and Yang Hao, who was proficient in sonic science, quickly made a small mechanism that could continue to happen.

After everything was prepared, Yang Hao found a dim corner to start his excavation work, which was so easy that he had a fight with digging tofu, and in just 10 minutes, Yang Hao dug through the 10-meter-thick soil layer and returned to the "packaging workshop" where Salonon was unknowingly.

Without staying too long, Yang Hao found a suitable location to continue digging, and after passing through the "production workshop" and "smelting workshop", Yang Hao arrived at the lowest level of the lava crypt - the lava steel mine.

There are countless scorching abnormalities here, and fiery red magma often leaches out of the crevices of the rocks, so you need to be very careful when walking.

"Damn! The temperature here is at least 50 degrees, and the ground is hot through your boots, which is really hell. ”

The temperature of the magma overflowing from the surface does not exceed 1,300 degrees Celsius, while the temperature is generally between 25 and 30 degrees, but the semi-enclosed structure here locks up most of the heat and directly multiplies the temperature.

The people who work here are the lowest gray dwarves and the slaves of the alien race, although the former is in charge of supervising the slaves, but they also have to mine in this steamer-like hell, and they are worried that the sudden magma will swallow them, so no matter who they are, their expressions are numb and lifeless.

When Yang Hao passed by, he just mechanically continued the movements of his hands without any reaction.

Seeing this, Yang Hao let go of his courage and leaned towards the center of the mine.

The closer to the center the place was, the higher the temperature, and after a while, Yang Hao found that the front was bright, and when he looked closely, it was actually a lava lake.

PS: To get to the bottom of it, Brother Gao Leng is miserable.
