The master tells the origin of the ancient plate.

At the end of the Southern Song Dynasty, the anti-Jin hero Li Bao followed Yue Fei to fight in the south and the north, and made many military exploits. Later, in the Battle of Tangdao, Li Bao won a great victory against the 70,000 Jin army with 3,000 troops, which not only saved the Southern Song Dynasty, but also became famous all over the world, because in the history of world wars, it was the first large-scale use of gunpowder. Therefore, this battle is recorded in the annals of war history.

Li Bao retired to retirement in old age, coinciding with his wife's birthday, and there was no rice at home. In order to give his wife a decent birthday, Li Bao racked his brains. He suddenly remembered that the Jin Army was stationed in the county seat, and there must be delicious food there, so he rode a war horse that had followed him for many years and galloped to the county seat. It was noon when Li Bao mixed into the city gate, knocked a golden soldier unconscious, put on the armor of a golden soldier, went straight to the kitchen of the enemy camp, knocked the cook unconscious, brought a large plate of roast sheep, put it in a cloth bag, and left quickly. When the Jin army noticed that he was suspicious, they swarmed after him, and he mounted his horse and galloped away. When he got home, the roast mutton was still hot, and he and his wife ate it happily. This big plate is the plate of Jin Bingsheng mutton, which belongs to the trophy and has been passed down to the present.

Lin Liu listened attentively, and then begged the master to evaluate Yue Fei's spirit. The master said that Yue Fei had to be evaluated under the historical circumstances at that time, he was a national hero who was loyal to the country, and Yue Fei's spirit was the patriotic spirit of the national tradition, which should be carried forward; Those who practice martial arts must first cultivate martial virtues, have a family and country in mind, have great love in their hearts, and love all sentient beings. Lin Liu understands and remembers it. When Lin Liu was in middle school, she admired Yue Fei, she deeply remembered Yue Fei's calligraphy of "return my rivers and mountains", and she could skillfully recite Yue Fei's "Man Jianghong". Now learning Yuejiaquan, she is full of strength.

After the criminal police arrested the apprentice who colluded with the antique dealer, they arrested the antique dealer and interrogated him overnight. The antique dealer confessed to other crimes, including the case of the unicorn inkstone that deceived and coaxed the mother who bought Linliu cheaply, and he had already sold it for 100,000 yuan, and the money had been squandered.

The master wronged Lin Liu, and relied on Lin Liu to recover the ancient plate, and felt guilty, so he taught Lin Liu martial arts and worked harder.

One day, the master took out an ancient book and said to Lin Liu that this is the "Yue Fist Strategy" handed down by his ancestor Li Bao, which is said to be a gift from Yue Fei, and there are four sentences in front that no one can understand, and asked Lin Liu if he can understand his meaning. Lin Liu opened the yellowed ancient book, carefully opened the front page of the volume, and saw that the four sentences written on it were: "Mountains in the sea, birds in the air." Oxen pull the plow, pigs arch the mud. Lin Liu lingered for a while, and suddenly his eyes lit up and said: "The mountains in the sea are reefs, which means to guard against hidden arrows; Aerial birds, which means that martial arts practitioners must have a high realm in order to be flexible and free; Oxen pull plows, pigs arch mud, which means to use their own specialties to defeat the enemy. The master was very happy, clapped his hands, and praised Linliu for being so clever that he wanted to give the ancient book to Linliu. Lin Liu said: "This is your family heirloom book, it is too valuable, and the apprentice does not dare to accept it." The master said: "I'm old, and I don't have much time to live, and it's useless for people who don't know how to get it, so I can give it to you in order to pass on the spirit of Yue Jiaquan and Yue Fei." Lin Liu knelt down to accept the book from the master.

Lin Liu obtained this treasure book, copied it, and read it hard until late at night with the copy in his hand, insisting every day and comprehending the essence of the book.
