228. Otherworldly Physics Class

As Zhao Douan began to popularize physics,

at the deepest part of the Heavenly Master Mansion, within a quiet and serene courtyard.

Under the banyan tree, the Empress of Great Yu, dressed in the attire of the Kun Dao today, also met with one of the legendary figures of Great Yu, a Daoist Heavenly Master with the deepest experience and the most mysterious realm.

Zhang Yan Yi.

"You've come."

Tall and slender, with narrow eyes and a warm smile, Zhang Yan Yi had been waiting for a long time, sitting under the banyan tree and gesturing for the Empress to take a seat.

Beside him, Jin Jian was also present, her role today being that of a master's attendant child.

Now departing from her usual lively temperament, she dutifully carried over a tea table and poured tea for them.

"It's been a long time since we last met, Heavenly Master, you look even more distinguished than before."
