"Boom!"
At the South Suburb of the Capital, as "Test Number One," the cannon's muzzle spewed a bunch of blue smoke, the thunderous explosion reverberated through the woods, and Zhao Douan stood among the crowd, looking up at the sky as a plume of yellow smoke drifted up.
Then, from all directions, the thunderous chants of thousands of soldiers rose, deafening.
Zhao Douan dug his finger into his ear, turned his head to the person beside him, the head of the Firearms Bureau in the Divine Mechanism Camp, Chen Huoshen, and smiled,
"The progress is good."
The old acquaintance, Chen Huoshen, proudly stroked his beard and responded with a smile, "It's all thanks to your great teaching, sir."
Zhao Douan smacked his lips and criticized,
"Next time, we could add more pigment to the gunpowder so that it splashes brightly and beautifully in the air, just like daylight fireworks."
