Trickster Hunter.

Chapter 198: Origin Underground Palace
The mobile cabin suddenly began to accelerate, and the number indicating the moving speed on the holographic screen increased from zero to sixty before stabilizing. Thanks to the excellent buffering design inside the cabin, Sun Hang could not feel any shaking at all during the vertical descent.

Even the bottle of Coke he had just taken out of the refrigerator, the liquid inside remained in a very stable state.

"That 'Mr. Pei'...he lives underground? In that...the Houtu layer?" Sun Hang asked.

With the current momentum, it is obviously heading straight for the "Hou Tu" layer below the ground.

"No, it's deeper than Houtu... Mr. Pei's residence is located sixteen kilometers underground. We call it the 'Origin Underground Palace'." The entourage replied.

The Origin Underground Palace? Sun Hang always felt that this name seemed to have a slight connection with the original primary weird thing, but he knew very well that even if he asked, the other party would either not answer or with the authority level of this entourage, he could not access that level of secrets at all.

"Wow, sixteen kilometers... This is almost reaching the mantle, right?" Sun Hang chose to avoid the main issue.

For questions involving the original primary monsters, it is better to ask the boss himself directly instead of asking the little Karami who leads the way.

"Chunming City is located at the intersection of the northern Xiazhou plate, the Taihang Mountain fold belt, the Yanshan fold belt and the Ji-Liao fault basin. The thickness of the earth's crust is more than 30 kilometers... In fact, the Yuanchu Underground Palace is not the deepest place in the Tianshu Tower. The No. 9 test well, which started construction half a year ago, is expected to be dug to a depth of 25 kilometers. It will be used specifically to accommodate some special creatures." Before the accompanying personnel spoke, a virtual girl image appeared on the holographic screen in front of Sun Hang, who answered Sun Hang's questions very enthusiastically.

"AI?"

"Yes, I am the 90026th management AI of Tianshu Tower. I am happy to serve you." said the girl.

At first, Sun Hang thought that the voice of the AI ​​sounded familiar. After a moment of hesitation, he realized that it was the female voice that announced the incident at the entrance of the Jade Pill, which Sun Hang had mistaken for a real person.

A depth of sixteen kilometers is exactly sixteen minutes for the mobile cabin traveling at a speed of sixty kilometers per hour - Sun Hang just finished the last Oreo in the box, and the mobile cabin stopped in a stone chamber made entirely of dark black rock.

These dark black rocks have streamlined orange-red lines, which emit intermittent light like breathing, as if magma is flowing inside the stone. But when Sun Hang walked out of the mobile cabin, he found that the temperature inside the stone chamber was the same as the air-conditioned mobile cabin, maintaining the most comfortable 24 degrees Celsius for the human body.

"Welcome to the Origin Underground Palace." The holographic image of the AI ​​girl did not disappear when Sun Hang left the mobile cabin, but moved to the inside of the stone chamber and hovered beside Sun Hang.

"I thought it would be very hot underground." Sun Hang said casually.

"Based on sea level, the current depth is 15,975 meters. The normal temperature here should be around 270 degrees Celsius." The AI ​​girl responded.

"Two hundred and seventy degrees?" Sun Hang looked up at the dome of the stone chamber that was more than twenty meters high. "To maintain this temperature, the energy consumed for cooling alone would be enough to supply electricity for a standard-sized block in Tianfu City for the entire summer, right?"

"There is no high-power refrigeration equipment installed here. The ability to maintain a constant temperature is entirely due to these stone bricks." The AI ​​girl said. "Stone bricks?" Sun Hang squatted down and gently stroked the winding orange-red lines at his feet. Faintly, he seemed to feel a hint of the breath of the weird meme inside the stone bricks.

"These stones...are they strange things?"

"To be precise, it's a man-made weird thing." The AI ​​girl circled around Sun Hang, "These bricks come from the weird thing No. 59 Geng, the 'Origin Temple'. After being artificially edited into memes, they were made into building materials for the Origin Underground Palace. This is also the origin of the name of the Origin Underground Palace."

"The Temple of Origin? Is it an original primary environmental monster? But shouldn't the serial number of the original primary monster be zero? What's the matter with this Geng No. 59?" Sun Hang asked puzzledly.

"'The Temple of Origin' is not an original primary monster, it is just an underground cave located in the Bay of Plenty area of ​​New Zealand. Based on the traces of memes remaining in the cave, experts have determined that an original primary monster was once born in this cave, or that an original primary monster used this cave as a nest for a long time, so that the cave itself was infected by the meme and became a G-type monster." The AI ​​girl explained to Sun Hang in great detail.

"So, the geothermal heat is absorbed by these rocks?"

"The standard name of these stones is 1092 'Energy Concentrating Rock (A)'. The suffix A is the abbreviation of 'artificial'." The AI ​​girl said as she wrote the English word out of thin air in front of Sun Hang with her fingers. "All 'artificial weird things' have this suffix A."

The Xiazhou Federation rarely uses English alphabetical numbers or abbreviations... Obviously, the suffix A is an "imported product", which means that the person or organization who first started studying man-made monsters or proposed this concept in the world is likely to be from an English-speaking country.

"Energy-gathering rocks can absorb geothermal energy, store it, and release it under certain conditions." The AI ​​girl said, "The original purpose of building the Origin Underground Palace was to utilize this man-made weirdness. Every six months, the energy-gathering rocks in the underground palace will be replaced. The energy-gathering rocks that have absorbed enough energy will be sent to where they are needed, and new energy-gathering rocks will fill their vacancies."

"It sounds quite environmentally friendly." Sun Hang nodded. "Then what will these stones that have absorbed so much energy be used for? Will they be used as power banks?"

"The energy release process of the energy-gathering rock is very violent, and it is usually used as a weapon such as a bomb." The AI ​​girl said, "Of course, there are a few equipment equipped with special power reactors that can withstand the energy of the energy-gathering rock."

"For example?"

"Garuda." Yang Qi answered Sun Hang's question on behalf of the AI ​​girl, "That thing is powered by energy-gathering rock."

"Amazing." Sun Hang exclaimed from the bottom of his heart.

The four of them walked through a corridor also made of energy-gathering rock and entered a brightly lit hall. A burly figure like an iron tower sat up from the corner of the hall and walked towards Sun Hang with a stern face.

Sun Hang recognized this man. He was the first-level hunter "Iron Wall" who served as Professor Li's personal bodyguard at the combat meeting in Baqu City.
