However, in the following days, the "filial" Fifth Son would only come to greet him every morning, and then disappear for the rest of the day.
The Emperor did not mind until the third day when he inadvertently saw the Fifth Son returning with several large game, and the praises surrounding the Fifth Son's bravery aroused his curiosity. He called him over that night, and found out that this "filial son" had come out hunting under the pretext of serving his father.
The pretenses and falsehoods of the hunting grounds near the capital were no longer satisfying to the Fifth Son; he wanted to engage in actual combat.
By this time, the Emperor didn't care too much about this plump son. Two more days passed, and the Emperor had already discussed the return route to the capital with his close ministers. Suddenly, the sound of thundering hooves came from the outside, accompanied by earth-shaking tremors and colorful flames rushing into the sky.
