[Live History Broadcast + Immortality and Madness + Death by Remonstrance with a Coffin + Childhood Friendship + Cremation for All]
In the fourteenth year of the Zhengtong reign, Zhu Qizhen, the great war god of the Ming Dynasty, insisted on personally leading an expedition.
Despite the tearful remonstrations of the entire court, the fate of the Ming Dynasty hung in the balance.
Suddenly, a deafening suona horn sounded outside the Meridian Gate!
Gu Canghai, the centenarian Grand Secretary, childhood friend of Emperor Taizu, and veteran of six dynasties, was dressed in mourning attire.
He carried a large, red-lacquered coffin made of golden nanmu wood on one shoulder and smashed it through the Meridian Gate!
"Zhu Chongba! Open your eyes and look!"
"Your unfilial descendants are going to squander your empire!"
"Today, I, Gu Canghai, have come to pay my respects to the Emperor of the Great Ming... on his deathbed!!"
This scene was suddenly broadcast live from the sky to the Hongwu dimension.
Zhu Yuanzhang spat out his tea.
"That's... Crazy Gu? How come that old bastard is still alive? Is he a turtle spirit in disguise?"
"Wait, who is he going to bury with that coffin?!"
The curtain rises, revealing the crazy history of the Ming Dynasty:
[During the Hongwu era: He hanged himself in the Fengtian Hall and forced Zhu Yuanzhang to grind ink for him!]
[During the Yongle reign: He used cannons to force the Oirat leader to dance!]
[During the Xuande era: He skinned corrupt officials and stuffed their skins with straw to make wind chimes!]
Zhu Qizhen broke down: "Grand Tutor! I'm not going on the expedition myself! Move the coffin away!"
Gu Changqing grinned:
"It's too late! Your Majesty, I've already played half of my suona horn. You should lie down now!"
