"Cry-bang!" The mysterious only room door on the fifteenth floor finally opened the next moment.

At this time, Dovulhu flew in first, and then Guan Heng led the elder of the Sha clan to step in. What caught everyone's eye was a huge room.

The walls are inlaid with countless huge and shiny crystal spheres, used as lighting tools, making the whole room shine like daylight. There are countless workbenches of all sizes, with various bottles, jars and various utensils on them. The most eye-catching thing is that in a corner of the room, there are mountains of black stones, that is, god-controlling stones, with an astonishing number.

"Ah, this is..." The elder of the Sha tribe was shocked the moment he walked into this place. Guan Heng explained from the side: "This is the secret laboratory of the Titan researchers who have not appeared for thousands of years after the Sha tribe moved to the Stone Demon Fortress. It is also the central control tower of the entire Stone Demon Fortress. When the multi-headed snake monster reads the internal memory of the Stone Demon Fortress, I also knew where this place is and how to open it."

At this moment, the elder of the Sha Clan suddenly realized. He said, "It is the stone talisman multi-armed monster that is driven by my stone spirit power to open this place, right, Mr. Guan Heng?"

"That's right." Guan Heng said slightly at this time, "And there is another biggest secret in the Stone Demon Fortress, you never know it."

Hearing Guan Heng say this, the elder of the Sha clan immediately became curious. He hurriedly asked, "What's the secret?"

"As we all know, the Titans' magical scientific research direction has always been famous for its 'huge'." Guan Heng laughed at this time: "In fact, the research on the opening and controlling god stones of the stone talisman warriors is the Titans' debugging and evolution experiments for a 'ultimate weapon'."

Speaking of this, Guan Heng paused, he looked around and said with emotion: "According to the information I obtained from the first launch of the Stone Talisman, the Titans have actually been creating a certain level of huge Stone Talisman warriors, trying to use this light to load all the Titan elites, the Zongheng Saint Longpulun Great 6."

"A huge stone talisman warrior?" Dovre, who was flying in the air, suddenly landed on Guan Heng's head. She said in surprise: "If you want to control such a giant monster, then the core power source required - God Control Stone, wouldn't it require astronomical numbers?"

"It's right. Even the Titans, the direct descendant of the ancient gods, cannot have infinitely owned the material of God Control Stone, so they can only first understand the small stone talisman warriors to test the loss of black stones."

Guan Heng said this and walked to a workbench. He knocked on the table and said, "Just on the eve of the demise of the Titans, this giant stone talisman warrior was finally developed successfully."

When Guan Heng said this, Dovl and the elder of the Sha clan were both surprised. They asked in unison: "It's done, where is it?"

Guan Heng did not directly answer the other party's question at this time, but then said to himself: "But the completion of the giant stone talisman warrior did not stop the Titans from moving towards destruction. The researchers of the Titans had to evacuate before they could even use this most powerful Ming for the first time."

Speaking of this, a mysterious smile flashed across Guan Heng's mouth. He stared at the stone talisman driven by the elder of the Sha clan and said, "In this way, the highest magical science of the Titans was buried in the loess until... one day a thousand years later, the Sha clans who migrated to the Grand Canyon accidentally found traces of 'it'."

"Uh?! Mr. Guan Heng, you, are you talking... this..." The elder of the Sha clan was so shocked that he could hardly believe what Guan Heng said, but Dovre on Guan Heng's shoulder had already asked first: "Guan Heng, are you talking about this entire stone demon fortress, which is the giant stone talisman warrior Ming, a researcher of the Titan clan?"

"That's right, that's it. Here, the room on the top floor of the fifteenth floor, the main control room of the giant stone talisman warrior."

Guan Heng stretched out his hands and waved his left and right at this time. He said, "Look, all the workbenches here must be driven by small stone talismans, responsible for the body movement and limb movement of the "Stone Demon Fortress Warrior" respectively. The stone talisman multi-arm monster is the commander-in-chief here."

"Oh my God, this Titans's brightness is really shocking." Dovl said in a dislodged voice: "Although I have heard that Titans like to develop huge things, I didn't expect that their work really scared me."

"Hu, hu, hu... So that's it, so that's it." At this moment, the elder of the Sha clan was even more shocked and trembled with his voice. He murmured to himself: "I didn't expect that the stone demon fortress that our clan had lived in for more than a thousand years was actually a huge weapon. It's so funny. For so many generations of ancestors, there were no subtle clues at all."

"It's no wonder that the researchers of the Sand Clan in the past dynasties did not understand the mystery." Guan Heng said with his shoulders at this time, "Because you can never open the central control room on the fifteenth floor, so it's not surprising that we don't understand the real purpose of the Stone Demon Fortress. Now, it's time for us to start the Stone Demon Fortress, because we have to deal with the Phantom Dragon Legion and the Stone Demon Fortress warriors need to practice."

"Yes, my benefactor is right." The elder of the Sha clan said excitedly: "Since we have mastered the giant stone talisman warrior, this time we must kill the Dragon Clan Legion alone, so that these abominable invaders will die without a burial place!"

"Guan Heng, if you want to activate the Stone Demon Fortress, you must have a large number of God-controlling stones." Dovre thought of the energy problem at this time, and she said with some doubts: "Do you think the black stones here are enough?"

"Haha, look at the God-controlling stones piled up in the corners here, like a mountain, which should be enough to move the warriors of the Stone Demon Fortress." Guan Heng smiled indifferently: "Besides, don't we still have a whole God-controlling stone mine? I can use my space stone carving fragments to get back and forth there at any time, and energy is not a problem at all."

"Yeah, I remembered it after you said that." Dovre smiled awkwardly at this time: "I almost forgot about this."

"Dadada..." At this moment, the elder of the Sha clan drove the stone talisman multi-arm monster in front of the largest workbench, constantly tapping the buttons on it, and pulling the control lever from time to time. In a few seconds, he heard a loud bang in the middle of the room. The stone floor split in an instant, and a huge power furnace slowly rose up.
