"Ahhh~"
"Damn it..."
After a burst of electric sound, Ye Feng and the other two cried out in surprise.
The ground of the suspended waterfall they were standing on shook violently, the surrounding space distorted, and they almost fell.
"Ye Feng, this space doesn't seem very stable. Something is changing... it feels like it's about to collapse!"
Seeing this, Shen Yun Yao couldn't help but worry.
"It's above, the treasure chest fell from above!"
"Holy crap, what are you guys waiting for? Why aren't you going up?"
"Go up a fart! If you get touched by that mist, you'll turn into a pile of white bones?"
"Nonsense, I saw someone floating up along the river just now!"
"Bang!~ Clang!~"
...
At this moment, a commotion came from below the suspended waterfall, and someone was firing upwards.
"Yun Yao!"
Ye Feng nodded to Shen Yun Yao, who immediately understood and handed the "Huozhong Cangfeng" to Ye Feng.
Holding the "Huozhong Cangfeng", Ye Feng took a few steps towards the dark and ancient door.
After reconfirming the positions of some formations, he inserted the incomplete formation part of the "Huozhong Cangfeng" into a groove on the door.
"Whoosh!~"
Instantly, the "Huozhong Cangfeng" emitted a blue light, which quickly spread to the dark and ancient door.
Before long, the entire dark and ancient door was illuminated by the blue light, displaying an arcane formation.
"Click~ Click click~ Clang~ Click~"
At this moment, the "Huozhong Cangfeng" made a series of sounds, and its entire structure began to change, some parts retracting, others extending.
In a short while, the uneven structure of the "Huozhong Cangfeng" perfectly fit into the groove on the dark and ancient door.
Ye Feng pondered for a moment, then pushed the "Huozhong Cangfeng" forward, letting it slot into the groove on the dark and ancient door.
"Clang~ Ka La~ Click click~"
Immediately, the entire door opened, but the formation's light did not dissipate.
The interior of the door was pitch black. Ye Feng tentatively threw a searchlight inside.
Instantly, the interior of the door lit up, though it was somewhat dim...
"Damn it, hurry up and find a way up! A door seems to have opened above. The treasure of the ancient ruins must be inside!"
"Exactly!"
"All of y-"
"Zzzzt!~ Zzzzt!~"
Suddenly, a sound of electricity and white light attracted Ye Feng's attention.
The three of them immediately walked towards the source of the sound and soon entered another spacious room.
Inside the room, a large piece of transparent glass was presented before the three of them. Lightning and thunder crackled on the other side of the glass.
Below the large transparent glass was a control panel with various buttons, and the text on it was also arcane runes.
"Big Brother, on the other side of the glass, there are robots... and firearms floating in the air..."
After a brief inspection, Xiao Xiao walked to the large transparent glass and said with some surprise, "It looks like the energy guns used against us at Shuishanshan Mountain, and some ordinary machine guns!"
"Patta!~"
At this moment, Shen Yun Yao, holding a yellowed leather-bound book and examining it, pressed a few buttons on the control panel.
Instantly, the scene on the large transparent glass changed.
"This..."
Ye Feng was very surprised because he could see the scene outside Shuishanshan Mountain through this glass.
Outside, it was still dark, but there was already a hint of red light on the horizon, clearly indicating that the sun was about to rise.
"Yun Yao, what... is in your hand?"
Immediately, Ye Feng turned his head and looked at Shen Yun Yao with some confusion.
"It's an introduction to the control panel, or rather, the entire ancient ruins!"
Shen Yun Yao, while flipping through a thick stack of documents in her hand, said, "This ancient ruin should accurately be called 'Apocalypse Shelter No. 2' - 'Civilization Spark'." The lightning storms we encountered outside were actually emergency energy replenishment for 'Civilization Spark'!"
"'Civilization Spark' has special stealth and barrier capabilities. It only appears and communicates with the outside world through a teleportation array when it needs to replenish energy from lightning storms... which are the teleportation arrays we saw at the summit of Shuishanshan Mountain..."
"And... to deal with potential dangers, there's a no-dead-angle firepower net from the mountainside to the summit of Shuishanshan Mountain, composed of various machine guns, flamethrowers, grenades, arcane energy guns... wind blades, and water arrows..."
"The reason those guns and stuff appear to be unmanned, and can mysteriously disappear and reappear, is because that area has many tiny spatial teleportation arrays..."
Shen Yun Yao flipped through the book, and as she spoke, Ye Feng interjected, "Yun Yao, you said emergency energy replenishment?"
"En!"
Shen Yun Yao nodded. "'Civilization Spark's' original energy source is arcane energy. It can gather arcane energy from a certain area. When the arcane energy is insufficient, it will absorb energy from lightning storms as an emergency power source!"
"Moreover, according to the records in this stack of documents, the spherical lightning storms we encountered earlier were not extreme weather that occurred randomly in this area."
"Instead, they were programs pre-set by the creators of 'Civilization Spark' specifically for recharging the ancient ruins. If these spherical lightning storms are not summoned, they will find a place to discharge themselves..."
She paused and added.
"Holy crap... no wonder when I was at Shuishanshan Mountain, I felt like the falling lightning was absorbed by the mountain..."
"It seems that the spherical lightning storms I encountered with Xiao Xiao earlier were the lightning storms discharging themselves..."
After hearing Shen Yun Yao's words, Ye Feng immediately understood.
"Yun Yao, are there any messages about the Ark of Apocalypse in that stack of documents?"
Immediately, Ye Feng asked a crucial question.
...
