Wang Dahai chewed on these names. He had listened to their heroic stories since he was a child. There were stories about the Khitans, the Jurchens, and the Song people, but there were no stories about the Mongols. Why? Wang Dahai still couldn't figure it out, so he fell asleep again.

In the dream, he rode a horse and drew his longbow, galloping freely on the grassland, running from the east to the west. Everyone followed him, including Mongolians, Jurchens, Turks, Liao people and Song people. He bent his bow and shot an arrow, hitting a galloping eagle. When he looked closely, he found that it had become Emperor Zhao. He sat on a high throne and was shot to death by an arrow. Wang Dahai in the dream was not afraid, but walked up to the throne, took off Emperor Zhao's crown and put it on himself. He saw the people following him cursing, and he felt that they were irritable, so he took action. He beat the Western Mongolians, the Russians, the Western Xia people, the Jurchens, and the Song people. Everyone was convinced, and Wang Dahai found that he already had a big country!

Wang Dahai woke up in shock. He was surprised by his bizarre dream and his reckless behavior in the dream. However, his heart had never been so beating like this before, as if he had been reborn. The Khitans, the Jurchens, and the Zhao emperor had the throne. Why could the Mongols only fight the Japanese in the new barracks? Wang Dahai couldn't help but push his companion beside him, "I want to be the emperor!" His companion was tired all day and didn't hear what Wang Dahai said at all. He just responded subconsciously, "Okay, okay, you want to be the emperor."

Wang Dahai fell into a deep sleep, and this time he had the same dream he had always had. In the dream, he no longer used the Chinese name Wang Dahai. He remembered the Mongolian name his father had given him, the name he had taken from Temujin Uge, Temujin Borjigin. In the dream, he was no longer Wang Dahai. He became an emperor as great as the ocean. He became Genghis Khan. This time, he would not forget.
