"Could it be that this is the stolen Nine Yang Manual?" he mused, "That's right, Tai Shifu said that the Nine Yang Manual was written inside the 'Lengjia Jing' [Lankavatara Sutra]. These squiggly and curvy characters must be the Lankavatara Sutra in Sankrit. But why is it inside the ape's belly?"
This four-volume book was indeed the Nine Yang Manual; as for why it was hidden inside the ape's abdomen, no one in this generation knew. More than ninety years ago, Xiao Xiangzi and Yin Kexi stole the manual from the Shaolin Temple library, for which crime they were pursued by Reverend Jueyuan to the summit of Huashan [Mount Hua in Shaanxi] without any chance of escaping. It so happened that they had this dark grey ape with them, so they had an idea: they cut open the dark grey ape's belly, and hid the manual inside. Later on, Jueyuan, Zhang Sanfeng, Yang Guo, and the others searched Xiao Xiangzi and Yin Kexi's bodies thoroughly, but failed to find the manual, so that they let the two, along the dark grey ape, go down the mountain. [Author's note: please read 'Divine Eagle Gallant Knights'] And thus the Nine Yang Manual's whereabouts became the great mystery of the Wulin World for approximately a hundred years.
Later, Xiao Xiangzi and Yin Kexi took their dark grey ape and went to the far away Western Region. The two of them were suspicious of each other; each of them feared that when the other one had mastered the martial art of the Manual, he would kill him. Thereupon they kept their eyes on each other and neither dared to take the manual out from the ape's belly. Finally they arrived at the Jing Shen Peak of Kunlun Mountains; Yin and Xiao two people were plotting against each other. They fought until both of them sustained injuries. Thereafter this supreme manual of internal energy cultivation stayed hidden inside the dark grey ape's abdomen.
Actually, Xiao Xiangzi's martial art skill was slightly better than Yin Kexi's, but because he was hit by Reverend Jueyuan's fist on Mount Hua, his internal strength was shaken and he suffered serious injury; hence when he fought Yin Kexi later, he was killed instead of scoring a victory.
At the point of his death, Yin Kexi met 'Kunlun San Sheng' [Three Sages of Kunlun], He Zudao. Pricked by his own conscience, Yin Kexi asked He Zudao to go to Shaolin Temple and tell Reverend Jueyuan that the books were inside this ape's belly. However, by that time he was already delirious that his speech was incoherent; he said 'jing zai hou zhong' [scriptures inside the monkey], He Zudao heard it as 'jing zai you zhong' [scriptures inside the oil]. He Zudao did keep his promise; he went to the distant Central Plains and conveyed the message 'jing zai you zhong' to Reverend Jueyuan. Jueyuan failed to comprehend the meaning of the message. Rather than talking about it, he stirred up a big disturbance instead. As a result, the Wulin world enjoyed the addition of Wudang and Emei, two Sects.
As for the dark grey ape, it was fortunate to have Kunlun Mountain's immortal peach as its diet; with the spiritual influence of the heavens and the earth, after more than ninety years it was still capable of jumping around as if flying. The dark grey and shiny long hair covering its entire body gradually turned snow-white that it turned into a white ape. It was just that the manual hidden inside its belly had caused a digestive system problem that from time to time it suffered stomach ache. Finally the malignant skin ulcer was developed on its belly, which lasted until today, when Zhang Wuji took the books out. Speaking of this white ape, it had entrusted its great misfortune to a trusted friend. This whole story was so complicated that even if there were someone with intelligence a hundred times better than Zhang Wuji in the world, he would definitely not able to deduce it.
Zhang Wuji was lost in thought for half a day. Realizing he would not be able to solve this riddle, he did not take the trouble to think about it further. He took the big 'pan tao' presented by the white ape and took a bite, enjoying the fresh sweetness of the juice slowly flowing into his throat. It was indisputably better than the nameless fruits he found in the valley.
Finished eating the 'pan tao', Zhang Wuji thought, "Tai Shifu once said that if I can practice the 'Jiu Yang Shen Gong' [nine 'yang' divine strength/power] of Shaolin, Wudang and Emei, three Sects, then I can drive the cold poison away from my body. These three Sects' Jiu Yang Gong all came from the Nine Yang Manual. If this book is indeed the Nine Yang Manual and I practice according to it, then the end result will far exceed the result if I practice the three Sects' divine power separately. Since I have nothing to do in this valley, I'd better practice according to this book. Supposing my guess is wrong; that this book is actually useless, so much so that it is harmful to me, the worst that can happen to me is death anyway."
Without anything to weigh his heart down, he put the other three volumes of the manual on a dry place. He spread some straw over the books, and put three big rocks on top, for fear that the monkeys, being mischievous, would fight over the books and perhaps would tear the books apart into pieces. With the first volume in his hand, he started by reading it several times to commit its contents to his memory. Afterwards he would try to understand it and only then he would start practicing the first sentence. His thought was, 'Even if I succeeded in cultivating the divine strength from the book, and managed to repel the cold poison, I would still be imprisoned in this valley with steep peaks all around, could not get out forever. My days in this valley are long, if I can succeed today, good; if I must wait 'til tomorrow, it's also good. It doesn't make any difference. If I fail, I would have something to do to pass my boring days anyway.'
Strangely, with this win-or-lose-always-happy attitude, he made a surprisingly rapid progress. In only four short months, he succeeded to comprehend in detail the skill described in the first volume of the book, which he immediately trained accordingly.
Finished training the first volume, he did a quick calculation, and found that the date predicted by Hu Qingniu on which the cold poison would take his life had already come and gone. His body felt light and healthy, the 'zhen qi' [real 'chi'] flowed freely in his entire body, without any symptom of an illness. Previously, the cold poison would flare-up often; now, the interval between occasional attacks was more than a month. When the attack came, it was very light.
When he was halfway through the second volume, the cold poison inside his body had been driven out completely. Every day, other than cultivating his energy, he played with the apes and monkeys. When he picked the fruits, he would always give half to Zhu Changling. Thus he lived without worry or concerns, free and easy. However, to Zhu Changling, who was still on that little piece of platform, a day dragged past like a year. When winter came, his world was covered in ice and snow; the cold wind penetrated his bones. The hardships he suffered were beyond description.
