The Shocking and Extraordinary Romance of the Great Sage

Listening to Taoist singing in Zhengnan, the meaning is deeply engraved in my heart. After Guo Lao left, he began to plan carefully and plan to make a guide fish and turtle. In half a month, he prepared all the materials, including a trip to Magnet Mountain to collect magnets, and then began to carve wooden fish, wooden turtles, wooden ducks, wooden chickens, and wooden birds... On this day, Zhang Guolao came to see He was making it, and seeing how vigorously he was doing it, even his brothers and sisters were helping to make it, and they secretly admired him. Yu Zhengnan saluted and said:"Senior, it is not difficult to make such a small compass. Your Excellency told me about the compass made by Ma Jun during the Three Kingdoms. Can you try it out?"

Guo Lao said as if:"The ancient skills of making compass. It could not be passed down. Before the Three Kingdoms, it was said that someone had built a compass. During the Three Kingdoms, Ma Jun was a minister in the Wei State. He was a scholar who specialized in mechanical operation. He had the dream of recreating a compass. , determined to build it, but was ridiculed by many people, thinking that he was bragging.……"

"Ma Jun made a bet with those who underestimated him and promised Emperor Wei Ming to build a compass. The emperor set a time limit, so Ma Jun studied hard, worked day and night, and worked hard to design and build it. You know, this is no joke! If you are unable to take out the compass at the expiration date, or if the direction is wrong, it is the crime of deceiving the emperor! It will make you lose your head."

"Ma Jun took this big risk and was not afraid of being beheaded, and finally delivered the compass to Emperor Wei Ming for use as scheduled. Legend has it that the compass is so magical and so small and exquisite that no matter which way the wheels turn, the wooden fingers on the car always point south. Emperor Ming was overjoyed and praised Ma Jun. The officials who were betting were also full of praise, praising Mu Ren's clever pointing skills and Ma Jun's intelligence and ingenuity."

Guo Lao said:"'A journey of a thousand miles begins with a single step', this is what the sage said. Now, you have made great achievements in making many of those small guides. You can't be too high-minded and greedy, and I can't encourage others to grow. Besides, the compass has been lost. During the Northern and Southern Dynasties, Emperor Qi Gao heard that Ma Jun had made a wonderful compass during the Three Kingdoms period, so he handed over this important task to the two most talented and famous mechanical manufacturing experts in the dynasty. One was Suo Yuzuo from the north. The other one is Zu Chongzhi from the south. He also ordered them to make them separately, and when the time comes, they will take them out to compare who made the compass that is beautiful and accurate, and has a clear direction."

"After receiving the order from Emperor Qi Gao, Suo Yuzuo hurriedly selected first-class craftsmen and rushed to make it overnight, hoping to take the lead. Zu Chongzhi, however, took his time and did not start a big fight. Instead, he developed a wooden model and tested it many times. Suo Yuzuo's guide car has been finally assembled, but Zu Chongzhi's guide car has not yet been built."

"When the time limit expires, the open competition begins. Suo Yuzuo sent someone to bring in a large guide car with colorful and beautiful paint. The compass used in Zu Chongzhi's competition is simple in shape, small and exquisite. There is a beautiful woman cast in bronze, with her right hand pointing south."

"During the competition, Emperor Qi Gao and the Manchu civil and military officials watched the battle. The result is: when the Soyuzu-made compass car rotates and changes direction, the direction indicated is not south. But the compass car built by Zu Chongzhi was very accurate. Whenever the car turned left and right and changed direction, the finger of the beautiful woman always pointed south. Zu Chongzhi wins as the winner…………"

Zu Chongzhi also invented and produced: thousand-mile boats, timers, water mills, etc. He was the first inventor in the world to calculate the value of pi to more than seven digits.

Guo Lao said earnestly:"Yu Sheng, I'm telling you so much to enlighten you. It's not easy to succeed in a big thing in the world, so don't rush for success! You have to do it step by step, and you have to have steps to do it wisely, not by force."
