Tiger Soul Sub-Base.
Underground prison.
This was the deepest part of the Tiger Soul Sub-Base, as well as an area requiring the Highest Authority. It was dark and damp year-round, the walls covered in moss, while the air carried the scent of rust.
It was clear that this place had not been maintained for a long time.
Many of the old-fashioned light bulbs were nearing the end of their lifespan, and various metal switches and other items were covered in rust.
Only the cage remained brand-new, without a speck of dust.
This was a specially designed cage built for Tian Shu. Its metal bars extended deep underground, while even the floor inside was made of special metal and connected as one with the cage.
It ensured a complete three-hundred-and-sixty-degree lockdown without any blind spots.
At the same time, eighteen chains hung from the ceiling of the cage, wrapped around Tian Shu's neck, limbs, and other parts of his body, restricting his freedom.
Now that he had confirmed Tian Shu was one of the miracles Feng Qi had found in Mu Yao's memories,
Feng Qi became even more curious about him.
Unfortunately, Tian Shu had never been willing to acknowledge him. Feng Qi had asked several questions, yet received no response.
But Tian Shu was clearly very interested in Mu Qing. More precisely, he was interested in the Scarlet Rune Crystal on her arm, which he had called the "Scarlet Origin."
This indicated that he might know the detailed origins of the scarlet Rune Crystal.
Realizing that direct questioning would not draw Tian Shu's attention, Feng Qi needed a breakthrough.
After a moment of silence, he looked up at Tian Shu again.
"Tian Shu, do you know Mu Yao?"
Tian Shu's indifferent expression changed when he heard the name "Mu Yao."
