In the game "Yi Jian Feng Yun Jue", there are quite a few puzzle mini-games. Players who often play such games can easily solve them, but for beginners, it's a bit challenging. Some players don't know how to pass the He Tu mechanism in "Yi Jian Feng Yun Jue". When you reach Ling Gui Island during the main storyline of "Bihai Xianzong", you will encounter the He Tu and Luo Shu mechanisms. Although there are hints on the right side, many people still do not know the solution.

The He Tu mechanism usually imitates the layout of the ancient "Bagua Jiugong" (Eight Trigrams and Nine Palaces), based on the classical He Tu numerology. The mechanism arranges patterns and numbers in sequence, and players need to rotate or move the components according to the "number-shape-direction" correspondence rule, so that the numbers in the diagram correspond to the central light point or symbol that lights up.

The core of the Luo Shu mechanism is the "Jiugong Luo Shu" nine number filling color blocks alignment. The mechanism board has nine preset positions, which need to be accurately placed with symbols representing the five elements of metal, wood, water, fire, earth, or the Heavenly Stems and Earthly Branches. When the mechanism is restored, it gives audio-visual feedback, proving that the layout conforms to the Luo Shu principle of "five in the center, eight-one diagonally," showcasing the ingenuity of ancient Chinese mathematics.

If you really don't understand, during the actual operation, you can directly use visual feedback, that is, check if the mechanism lights up and if the runes appear, to confirm whether the layout is correct. For example, when the nine numbers are aligned, the corresponding symbols light up and the mechanism operates. This way, by trial and error, fortunately, this mini-game itself does not have steps or time limits.

For the He Tu mechanism, the order of the four spirits is: Vermilion Bird at the top, Black Tortoise at the bottom, Azure Dragon on the left, and White Tiger on the right. The difference between the two inner rings is 5, black 6 white 1 at the bottom, white 7 black 2 at the top, black 8 white 3 on the left, and white 9 black 4 on the right. The slower the ring rotates, the more it deviates from the correct position. Use the faster rotating ring to drive the slower one into the correct position.

This is a general introduction to how to pass the He Tu mechanism in "Yi Jian Feng Yun Jue". You must first understand the rotation pattern of the stone rings before you can correctly solve this mechanism. After the He Tu mechanism, there is another Luo Shu mechanism, a 9x9 grid, which is relatively simple. First, determine the four corners, with 2 and 4 on the upper left and upper right, and 6 and 8 on the lower left and lower right, then adjust the cross position.
