"Then I want to see the underground palace."

Emperor Tai'an agreed without any hesitation.

"No problem, I'll take you there right now."

As Emperor Tai'an spoke, he also took Li Hongzhao and Baili Tu inside.

The entrance to the underground palace is behind the bookshelves in the imperial study.

The mechanism was so cleverly designed that it was difficult for the average person to detect.

Behind the bookshelves lies a dark and deep staircase, seemingly leading to an unknown world.

It silently meandered down and disappeared into the darkness.

The world beneath the stairs seemed shrouded in a thin layer of mist.

However, none of this could stop Shi Yu's eyes.

Through the thin mist in the air, she saw an underground palace that ordinary people could not see.

The ornately decorated and resplendent pavilions stand there.

Every detail has been meticulously crafted, showcasing unparalleled craftsmanship and artistic charm.

The eaves and brackets are like a phoenix spreading its wings, light and agile; the doors, windows and railings are carved with various myths, legends and historical stories, lifelike.

The walls are covered with colorful murals, the figures are lifelike and the scenery is depicted in great detail, making people feel as if they are in a magical and ancient world.

However, the most eye-catching feature is the lifelike black dragon in the very center of the underground palace.

Shi Yu could feel the material.

It is clearly made of the same material as the guardian pillar of the nation.

It also exuded a faint, unique aura belonging to the Great Demon Dragon of the Abyss.

She had been to the Imperial Study more than once before, yet she had never noticed.

It seems that the fog in the underground palace and the special bookshelves blocked her senses.
