The Chou armies, with gongs beating and drums rolling, advanced for a final effort, the slaughter being so great that even the devils wept and the spirits wailed. Wên Chung was eventually driven back seventy _li_ to Ch'i Hill. His troops could do nothing but sigh and stumble along. He made for Peach-blossom Range, but as he approached it he saw a yellow banner hoisted, and under it was Kuang Ch'êng-tzu. Being prevented from escaping in that direction he joined battle, but by use of red-hot sand, his two-edged sword, and his Turn-heaven Seal Kuang Ch'êng-tzu put him to flight. He then made off toward the west, followed by Têng Chung. His design was to make for Swallow Hill, which he reached after several days of weary marching. Here he saw another yellow banner flying, and Ch'ih Ching-tzu informed him that Jan Têng had forbidden him to stop at Swallow Hill or to go through the Five Passes. This led to another pitched battle, Wên Chung using his magic whip and Ch'ih his spiritual two-edged sword. After several bouts Ch'ih brought out his _yin-yang_ mirror, by use of which irresistible weapon Wên was driven to Yellow Flower Hill and Blue Dragon Pass, and so on from battle to battle, until he was drawn up to Heaven from the top of Dead-dragon Mountain.
Ch'ien-li Yen, 'Thousand-_li_ Eye,' and Shun-fêng Êrh, 'Favourable-wind Ear,' were two brothers named Kao Ming and Kao Chio. On account of their martial bearing they found favour with the tyrant emperor Chou Wang, who appointed them generals, and sent them to serve with Generalissimo Yüan Hung (who was a monkey which had taken human form) at Mêng-ching.
Kao Ming was very tall, with a blue face, flaming eyes, a large mouth, and prominent teeth like those of a rhinoceros.
Kao Chio had a greenish face and skin, two horns on his head, a red beard, and a large mouth with teeth shaped like swords.
One of their first encounters was with No-cha, who hurled at them his mystic bracelet, which struck Kao Chio on the head, but did not leave even a scratch. When, however, he seized his fire-globe the brothers thought it wiser to retreat.
Finding no means of conquering them, Yang Chien, Chiang Tzu-ya, and Li Ching took counsel together and decided to have recourse to Fu Hsi's trigrams, and by smearing them with the blood of a fowl and a dog to destroy their spiritual power.
