Emperor Wu of the Han Dynasty sued for peace in order to keep the Silk Road unblocked, and sent Su Wu, a special envoy from the Western Regions, to the Xiongnu camp as a hostage. The leader of the Huns, Mao Dun, saw that Su Wu liked him very much, recognized him as his righteous son, and promised that Su Wu would be the acting king if he captured Tianzhu. One day the Huns held ancestor worship activities, Su Wu saw the Huns facing Kunlun to pay homage to their ancestors, and couldn't help crying, thinking that everyone else was here to worship their ancestors, but he was far away from his hometown to be a hostage here, and he couldn't help but feel sad.

Just when Su Wu was sad and crying, he was found by Mao Dun and asked the reason, Su Wu was speechless for a while, and then the Mafu Kunlunu who followed Su Wu next to him hurriedly helped Su Wu relieve the siege and said: "The envoy was too anxious to drink just now, and his heart hurts." Mao Dun ordered Kunlun Nu to help Su Wu return to the camp to rest.

Back in the camp, Kunlun Nu reminded Su Wu that he should be careful everywhere in the camp now, and be patient and wait for the opportunity, there will always be a day when he will go home. At this time, Mao Dun also came to visit Su Wu in the camp, and when they were chatting with each other, suddenly there was a sound of birds outside the camp, as if to say: "Su Wu Su Wu, if you don't leave at this time, when will you stay?" Maudon was shocked and asked what the bird was talking about. Su Wu said: "King, this bird is scolding you!" Wait until I take an arrow and shoot it down!" ”

So Su Wu took the bow and arrows, and secretly said in his heart: "Bird, bird, if you want to save me, please guide me to escape from the horse camp." After reading it, an arrow was shot, but I didn't expect the arrow to be caught by the bird and fly away. At this time, Kunlun Nu hurriedly brought a sweaty horse and said to Su Wu: "Special envoy, quickly get on the horse and chase the arrow back!" ”

Su Wu turned over and got on his horse, took the Kunlun slave horse whip and came out of the camp! Maudun laughed behind him and said, "My son is so real, how much is an arrow worth?" After laughing, he returned to the camp and continued to drink wine and eat meat. During the banquet, a Xiongnu military advisor said to Mao Dun: "The envoy rode a horse and galloped, kicked several barracks, and kicked and injured many soldiers. Mao Dun didn't think so, and scolded the military advisor that such a trivial matter was not worth reporting me. The generals who were drinking together at the scene reminded Mao Dun: "It doesn't matter if the envoy of Su Wu kicks the barracks, I'm just afraid that if he falls off the horse and gets hurt, what if he gets hurt?" When Maudun heard this, he felt reasonable, so he rode his horse and led the soldiers to chase him out.

Mao Dun chased after him and shouted: "Come back, son, we don't need that arrow, I have an arrow here!" Su Wu was frightened when he heard Mao Dun chasing after him. Mao Dunxin said that this is not the way, so he took out a bow and arrow and shot at Su Wu's horse, Su Wu whipped the horse, and an arrow hit the gem inlaid on the horse whip, snapped, fell off the horse on the spot, Mao Dun slapped his thigh and said, "It's broken!" Don't break it. ”

Su Wu got up from the ground and looked up to the sky and sighed: "Is it true that I can't go back?" At this moment, the gem and jade shot were in the air, like a match being ignited with a "swish", as if going back in time, a door of time and space slowly opened, and a "swastika" word space-time gate suddenly appeared in front of him like a tray, Su Wu didn't care so much, picked up the whip and hurriedly turned over on the horse, this horse was really magical and carried Su Wufei through the time and space gate, and the Maotun cavalry continued to chase behind. When the horse ran to the swastika of the space-time gate, suddenly the black fog in front of him was rolling, black snow was floating, and the poisonous smoke was rolling, and the envoy of Su Wu was gone.

The smoke was filled, the heavens and the earth were cloudy, there must be supernatural energy helping Su Wu escape.

Maudun sighed in the back and said, "My godson turned into dust in a blink of an eye, and I blame this wild horse for being wild and unruly and lost my godson, and returned to the camp after worshipping."

Su Wu escaped, the life of nine deaths he had just experienced, thinking about it and its grotesqueness, could it be the energy that the legendary super element was pierced through the heart with an arrow?

Emperor Wu of the Han Dynasty listened to Su Wu's report and felt that it was absurd and unacceptable.

He looked at the horsewhip carefully, and the gem inlaid on the handle was indeed pierced through the heart by an arrow, but he was still not sure, so he asked people to go to Sima Qian to verify it.

The demote of Su Wu to a counselor is not mentioned.
