Zhang SanFeng still had one set of martial art skill that was extremely worthy of pride, it was called “Zhen Wu's Seven Spheres Formation.” The Wu Dang sect offered worship to the deity Zhen Wu, and when Zhang SanFeng saw the pair of statuettes comprising of a snake and a tortoise that was always situated in front the statue of Zhen Wu, he thought to the SheShan and GuiShan located at the juncture between the ChangJiang and the HanShui River Valleys. When he thought over the agile lightness of a long snake contrasted with the lumbering heaviness of a tortoise, he also thought to how the diety Zhen Wu was able to place his leg on the shell of a tortoise while his right leg rested on the body of a snake, thus capturing the essence of the most lithe and cumbersome objects' fundamental nature. He immediately took off that moment, journeying through the night to arrive at the Northern areas of the HanShui River Valleys to study the two She and Gui mountains. Through the undulating twists of the SheShan and the stately stableness of the GuiShan, he was able to create an incredibly brilliant and mystical martial art skill.
However, the She and Gui mountains were so majestic in their force, that it caused the martial arts inspired by the intensity of the mountains to be so profound and boundless, that it encompassed a vast field and became something of which could not be fully implemented through one person’s power. Zhang SanFeng quietly stood by the river’s bank and for three days abstained from drinking a single drop of water or consuming a tiny morsel of food. He concentrated all his energies into mulling over this skill, yet was still unable to solve this problem. But during the early dawn of the fourth morning, he watched the sun rise from the East to cast a million streaks of wavering golden slithers and flickering spots of sparkling illuminations on the face of the river. He was suddenly enlightened and after engaging in a hearty laugh, he returned to the Wu Dang mountain and brought his seven disciples to him in order to relate a martial art skill to each one of them.
These seven different forms of martial arts when executed separately is of course each an embodiment of brilliance and exquisiteness in their own right, but if two people combine their efforts, the brothers can support and facilitate each other by simultaneously fostering their attack while maintaining their defence, causing their power to be increased even further. If three people simultaneously executed their moves, their power would be double that of the combined effort of two individuals. The power of four people would equal to that of eight first rate fighters while five people amounts to the force of sixteen fighters and six fighters will be equivalent to thirty-two fighters. By the time they can gather the efforts of seven fighters simultaneously, it would be analogous to having the collective force of sixty-four of the present era’s first-rate fighters attacking all at once. Within the present era, the number of martial artists who can be classified as a first rate fighter was merely a small list comprised of twenty or thirty people, what are the chances of having the opportunity to gather together all these first rate fighters? Even if they could be gathered together, within these fighters there were the good and the evil, the compassionate and the malicious, how could they possibly co-operate together as a group?
Because this skill of Zhang SanFeng’s was inspired by the tortoise and snake statues that stood by the foot of deity Zhen Wu, it was therefore titled as the “Zhen Wu Seven Spheres Formation.” At that time, he painstakingly pondered over the difficulty in making up for the vacancy in the west end while one watched over the east, which would simultaneously afford opponents with the chance of taking advantage of the exposed vacancy in the Southern and Northern ends. It was only later when he came up with the solution of directing his seven disciples to execute this skill as a group was he finally able to resolve this problem. Although he couldn’t help but be a little disappointed over the fact that this “Zhen Wu Seven Spheres Formation” could not be worked out in such a way so as to enable just one person to executed it, but when he thought to, “If this skill really can be executed through the power of just one person, then wouldn’t that mean just one person’s power would be enough to defeat the combined force of sixty-four first rate fighters? Is that not a much too absurd and arrogant idea?” and couldn’t help himself from laughing while being at a complete loss of words.
Since the Seven Heroes of Wu Dang have made their name within the martial arts world, there has not been an encounter in which they were not able to achieve the upper hand. Regardless of how powerful of an opponent they may be pitted up against, the most they would require would be just the combined efforts of two or three brothers in order to conquer and be victorious.
