After they got out of the dining room, Hestia walked to a metal door with Tianxuan and stopped, said hello to the two guards, the door opened, and then they passed through a narrow passage to the outside, and suddenly everything around them was very bright, because they came to the edge of the inverted cone, and below it was the sea of hot lava. At this time, he could clearly see countless pale cyan cylinders towering high in the magma sea, each towering column had an inverted cone on it, and between each cone there were two pale cyan sky bridges connected, thus forming a huge building complex. Tianxuan couldn't help but be amazed by this magnificent structure. Hestia looked at Tianxuan's expression and smiled slightly smugly, and then said, "Let's go!" I'll take you to the front to see the construction of our smelting pool. ”

When they crossed one of the overpasses, they came to the smelting pool in Hestia's mouth, which was actually a huge furnace, the furnace was filled with white magma, and next to the furnace was a number of lifting equipment connected to the many hangers above, and below the hangers were several operating stations, on which were placed various tools and crystal ores, which looked very doorways. When Tianxuan wanted to take a closer look, he instantly felt an abnormal heat wave coming, the temperature was really hotter than the equator, and the air seemed to be burning.

A lot of sweat flowed down Tianxuan's forehead, and his eyes were fascinated. At this time, Hestia brought a silver-white cloak and put it on Tianxuan, and suddenly his whole body cooled down. Although it was much better, Tianxuan was still panting for breath when he was not used to it for a while, he glanced at Hestia and found that she didn't seem to feel hot without a cloak, as if she didn't sweat much, so he asked: "Lady Hestia, I feel that you seem to be very accustomed to this temperature and don't feel hot?" ”

Hestia blinked her red eyes and smiled sweetly, "You're right, I don't feel hot. That's because our Mayans are different from you surface people, we live underground for a long time, and we live on geothermal heat, so this temperature is normal for us. ”

Tianxuan nodded in understanding: "So that's the case, no wonder you're not afraid of heat, isn't it like magma used to bathe every day like water?" ”

"Uh, uh, what's this?" Tianxuan's question surprised Hestia, and it took a long time to react and say, "We still use water, not magma!" This cold joke really made Hestia cry and laugh.

At this time, a strong man who was also wearing a sundress, about 1.8 in height, with a big beard, although not as burly as Hercules, was also considered strong. He said to Hestia, "Hestia, where did such a child come from?" ”

"Oh! If you come up from the ground, you can see it by looking at him! After Hestia finished speaking, he pointed to the strong man in front of him and said to Tianxuan, "Tianxuan, this is our foundry Jason Klosso, and the tools and instruments of the entire streamer layer are all from him!" ”

"Wow! It's so powerful! Mr. Jason Klozo," Tianxuan said with his eyes wide open.

"Of course, I'll show you my masterpiece!" Jason Klozo not only felt tall when he heard the admiration of others. Although he is very good, but after Tianxuan arrived in the main city of Maya, these can only be regarded as a drop in the bucket!

Suddenly, Tianxuan's curiosity came up, and he ran to the workbench in front of him and began to fiddle with various utensils, and suddenly he found the square box used by Hercules in the Iron Tree Layer, so he asked in surprise: "Mr. Jason, what is this square box, I saw someone use him to create a pink heart in the Iron Tree Layer, and after popping it out, he actually shot the big spider that fell to the ground hundreds of meters away?" ”

"This is called an inflatable cannon, and its principle is to compress the surrounding air, because there are too many substances such as iron oxide at the iron tree level, so there are a little red impurities when compressed. After compressing it into a heart-like shape, a violent explosion shock wave will be generated when this part of the air is suddenly ejected, so it will eject the spider for hundreds of meters! Jason Krozo paused before explaining, "However, the inflatable cannon you are holding now is much more powerful than what you see in the Iron Tree Layer. The durability and utility level of each tool is directly related to the magma properties used in the forge. The white magma is the hottest here, and the purity of the crystal ore smelted in it is also the highest; The dark red is the darkest, so the impurities that come out are also the most, and the quality of the tool is also the worst! ”

"I know it's the same as the color of a flame, the more impurities, the darker the color. Right! Tianxuan said.

"Yes! That's it! Jason Klozo said.

"But I don't understand the question of what is the reason why Mr. Sal said that the magma here will not erupt?" Tianxuan asked.

"This area was actually all condensed crystals or ores before development, and it is also far away from seismic and magmatic eruption zones. The sea of magma you see is a channel that we have carved in the direction of the magma flow and diverted it. Jason Klozo explained.

"Well, to put it this way, is to dig a canal, just like the artificial canal on the ground. I kind of get it! "Tianxuan has a general understanding of the situation.

"It's just part of the process, these cylinders are the transport pipes that pump the magma out of the smelter, but do you know why it's so high? That's because it's for safety; Second, magma volatilizes a lot of toxic gases, and we use cleaning materials such as diatomaceous earth made of silicate ore unique to the streamer layer to neutralize these exhaust gases. Jason Klozo continued, "When the magma rises, the toxic gases in the tunnel will be emitted to the adjacent channel with pressure and neutralized with cleaning agents such as diatomaceous earth, and then the neutralized solid impurities will slide down the adjacent channel due to gravity and be discharged into the recycling station at the bottom, including the waste from the smelting of the furnace above us. This waste is used to make the foundation of our underground promenade and other roads. As he spoke, Jason Klozo took out a piece of diatomaceous earth and showed it to Tianxuan.

After listening to the introduction, Tianxuan couldn't help but be surprised when he looked at the diatomaceous earth they made, such a complex recyclable process was so perfect that there was no waste at all. I have to admire the wisdom and foresight of the Mayans, who can handle production, manufacturing, and environmental protection so well, compared to the fact that many resources on the ground are wasted and cause a lot of pollution.

While Tianxuan was constantly thinking, the boiling furnace suddenly boiled like boiling water, as if something was about to come out. At this time, I only heard Jason Klozo shouting: "No, run!" Come with me! ”
