"From that description, it sounds a lot like the Sage of Six Paths."
Jun Ruyan immediately thought of him.
The other members of the Exploration Department nodded as well.
Luo Yu blinked in surprise. "You know about the Sage of Six Paths too?"
Ye Lingbo quickly explained, "You're underestimating us."
"We're among the Anbu's best, after all. We have clearance to access plenty of inside information that even many Kage-Level Ninjas don't know about."
Luo Yu slapped his forehead.
That was true.
He had never used the Anbu's intelligence network.
Naturally, he had no idea what information was available within the Anbu.
The members of the Insect-Type Development Department were all Anbu elites, with higher information clearance than ordinary Anbu members.
It was hardly surprising that they knew about the Sage of Six Paths.
That made it easier for them to understand exactly who had created the ruins before them.
It spared Luo Yu from having to explain events from the Primordial Era, such as those involving the Moon God.
Ye Lingbo took a deep breath.
"Before we set out, I heard that the Space-Time Tunnel was most likely a back door deliberately built during the Primordial Era."
"The ancestor who developed this tunnel intended to give future generations of humans on Blue Star the ability to launch a counterattack against the Otherworldly Plane."
"Now it seems that ancestor was the Sage of Six Paths."
"The ruins here must also be a way station he built."
Little Bunny answered confidently, "That's right. These ruins were built with materials that block detection."
"They're generally very difficult to detect."
"And this teleportation array was probably meant to send people back to Blue Star too."
Luo Yu added, "Presumably, the investigators who reached the other planes have also appeared inside similar hidden ruins."
