Why does Xingtian have no head?

According to the "Book of Mountains and Seas: Overseas Western Classics": "Xingtian and the emperor came here to fight for gods. The emperor cut off his head and buried him in Changyang Mountain, with his breasts as his eyes and his navel as his mouth. , Cao Ganqi Yiwu

Translation: Xingtian is Xingtian, Xingtian and Huangdi competed for the throne here, Huangdi cut off his head and buried him in Changyang Mountain. The two breasts are eyes, and the navel is used as the mouth, and the stems are used to dance.

Xingtian was the leader of a tribe in the eastern part of the ancient Yandi tribe. He later joined the Dongyi tribe and became the main leader of the Jiuli tribe. In the battle with the Yellow Emperor, he was beheaded by the Yellow Emperor. This was called Xingtian. >When Emperor Yan was still the Emperor of Heaven who ruled the entire tribe, Xing Tian was a minister under Emperor Yan. He loved songs throughout his life and once composed the music "Fu Plow" and the poem "Harvest" for Emperor Yan, with the general title of "Bu Mou". To praise the happy life of the people at that time.

Later, Emperor Yan was overthrown by Huangdi and moved to the south to become the Emperor of Heaven. Although he swallowed his anger and did not fight against Huangdi, his son and subordinates were not convinced. When Chi You raised his troops to resist the Yellow Emperor, Xing Tian wanted to participate in the war, but it failed because of Emperor Yan's determined efforts. Chi You and Huang Di failed in the battle, and Chi You was killed. Xing Tian could no longer suppress his angry heart. , so he secretly left the Southern Heavenly Court and went straight to the Central Heavenly Court to compete with the Yellow Emperor.

The weapons used to punish the angels were Qi, a giant axe, and a bronze square shield. , called Qian in ancient times. Holding a bronze square shield in his left hand and a flashing ax named "Qi" in his right hand, Xingtian passed through the pass and cut through many heavenly gates until he reached the Huangdi's palace where he was leading the ministers. Watching the fairies singing and dancing in the palace, they suddenly saw Xing Tian waving "Qianqi" to kill the general. He was furious, picked up his sword and started fighting with Xing Tian, ??stabbing with swords and axes, and fought from inside the palace to outside the palace. The heavenly court went to the mortal world, and went straight to the Changyang Mountain. Xingtian fought with the Yellow Emperor, and was finally beheaded by the Yellow Emperor. He was buried at the foot of the Changyang Mountain. , using his navel as his mouth, he continued to swing his shield and axe, and fought against the Yellow Emperor again.

The "Yuanyang Zhilue" said: Xingtian possesses the Holy Spirit Stone, and he fights Yinglong with Ge Qi. During the fight, the sky was dark and the earth was dark, so Huang Di took the opportunity to sneak up on the dragon and cut off his head, but Xing Tian still stood tall and continued to fight on the battlefield. Later, the Nine Heavens Xuannv sent Xuantian Yunu to say something to Xing Tian. He said: "You can kill the Emperor of Heaven without a head." He fell down and was later buried in Changyang Mountain. Xingtian died in the Battle of Zhuolu.
