In the "History of the North", there is a record of a fierce man named Lu Cao, FanYangren. He was Erzhu Rong's subordinate general, and Erzhu Rong specifically ordered him to guard Youzhou to guard against the invasion of Ruoran. The reason why he said that he was a fierce man, Lu Cao was nine feet long, with a leopard head and eyes, and his voice was like a brass bell. At that time, there was a monk who claimed to be infinitely powerful, called Tan Zan, who often told others that only Lu Cao could compete with him in the world. It is said that the hairs on Lu Cao's arms look like pig's bristles.
When Lu Cao was defending Youzhou, the Ruoran tribe came to invade Fanyang, and Lu Cao stood on the city wall with a bow and arrow, and shot out three hundred steps with one arrow. After shooting, Lu Cao threw his bow to the general of Rouran, and none of the rouran generals could pull his bow open, so they had no choice but to withdraw their troops. After Hercules Tanzan heard about this, he was convinced of Lu Cao, believing that he was second and Lu Cao was first.

After Erzhu Rong was killed, Gao Huan rebelled against the Erzhu family, and Lu Cao took the opportunity to occupy Jizhou. After the Erzhu family was crushed by Gao Huan, Gao Huan's army came to Jizhou, and Gao Huan heard about Lu Cao's resistance to Rouran and knew that Lu Cao was a fierce general. Therefore, Gao Huan bribed Lu Cao with the high-ranking official Houlu, and Lu Cao did not dump Gao Huan. Then Gao Huan said to Lu Cao, If you are willing to submit to me, wouldn't it be better to be called Er Cao by my third uncle Gao Ao Cao?
To know that Gao Ao Cao was compared to the existence of Xiang Yu by the people at that time, Gao Huan compared Lu Cao with Gao Ao Cao, which shows that Gao Huan recognized Lu Cao's strength. This is not better than good, Lu Cao heard Gao Huan say this, angry, scolded Gao Huan, saying that Gao Huan found a farmer to compare with him and such a national soldier.
It means that Gao Huan is insulting him, and from here, Lu Cao still knows Gao Ao Cao. When Erzhu Rong drove Gao Ao Cao's brothers back to his hometown, he did not let his brothers go to farm, and although Gao Ao Cao was fierce, Lu Cao looked down on him in his heart.
Gao Huan saw that the persuasion could not be achieved, and immediately began to attack the city, and the wars in ancient China did not rely on personal force to win victory. Lu Cao was brave, but Gao Huan's side was also a fierce general, not to mention that it was difficult to defeat four hands with two fists, and After Lu Cao's defeat, he led his men from Jizhou to the island.
When Lu Cao came to the island, he found the skeleton of a giant, and the reason why it was said to be a giant was because Lu Cao used his two tibias to make a horse mallet. The giant's skull was used to make a manger for feeding horses, the tibia was six feet long, and at the end of the Southern and Northern Dynasties, the length of the Southern and Northern Dynasties was calculated differently, one foot in the Southern Dynasty was equivalent to the current twenty-five centimeters, and one foot in the Northern Dynasty was equivalent to about thirty centimeters in the present.
One zhang is ten feet, that is to say, the tibia of this giant is sixteen feet long, which is converted according to our current units, that is, the length is about four meters and six meters. Lu Cao made two hammers, kept one for himself, and sent the other one to Gao Huan. This is not to please Gao Huan, but to make Gao Huan ugly, this thing has multiple Lu Cao himself knows.
After Gao Huan received a gift from Lu Cao, Gao Ao Cao had already been killed in the Battle of Heqiao. Therefore, at that time, of the many generals under Gao Huan, only Peng Le could barely lift them. When Lu Cao found this giant, he also found a "secret book" next to the giant, and later Lu Cao heard that Peng Le could hold up the horse mallet he sent, so he gave the book to Peng Le as well.
Lu Cao fell ill after decomposing the giant's skeleton, and every night he would hear strange sounds, and the healing with medicinal stones was ineffective, so he found a witch divination. The witch said that Lu Cao had provoked the gods, and after the treatment was ineffective, Lu Cao fell ill and died.
The hammer that remained with Lu Cao could be used by Lu Cao, but Peng Le only barely lifted it, but he could not use it, so Peng Le enshrined the hammer with the "Secret Book" at home. Later, after Gao Yang declared himself emperor to establish Northern Qi, Peng Le was given the title of King of Chen Liu for his merits.
Not long after Gao Yang claimed to be the empress, a vision appeared in the sky, and Gao Yang asked the official in charge of divination to ask. The fortune teller told Gao Yang that this was a sign that there was a minister who wanted to rebel, and another day Liu Zhang came to Peng Le's house as a guest, and saw the giant bone horse mallet sent by Lu Cao at that time, which was enshrined by Peng Le, Liu Zhang was curious and went to look at it, just then he just saw the "Secret Book" that was enshrined together.
Liu Zhang was a former official in charge of Xiangzhou, and after seeing the book, he opened it with curiosity, only to see that it read, "Heavenly King Chen Stays in And Merges The Prefecture." After returning home, Liu Zhang told Gao Yang what he saw at Peng Le's house today, and with the words of the fortune teller, Gao Yang thought that Peng Le was going to rebel, so he killed Peng Le.
When Peng Le was killed, the Western Wei general Yang Zhong was given the title of Duke of Chen Liu County, but in fact this prophecy was to say Yang Zhong. Later, when Northern Zhou attacked Northern Qi, Yang Zhong first led an army into the city of Xiangzhou. Later, his son Yang Jian established the Sui Dynasty and posthumously honored Yang Zhong as Emperor Wuyuan.
