Lion, the first one to fly on the sky!
On the second day, the Empress and all the officials went to the Imperial Academy to witness a miraculous event in the sky.
The students and teachers of the Imperial Academy didn't attend classes either; they all gathered to observe.
Inside the square, several students were busy manipulating and crafting a large airship, which was expanding outward and even larger than a basketball court.
At another spot on the airship, there was an opening where a basket was continuously hung. Several students were busy raising torches to heat the airship, causing it to expand.
The Empress, not understanding, asked, "My dear, what does this mean? When can the airship fly into the sky?"
Lion stood beside the Empress, gazing at her exquisite beauty, and smiled, "Your Majesty, the students are heating the airship with hot air. By absorbing enough heat, the airship will expand and be able to fly into the sky!"
