The Three-Body Problem

“Ji Chang, sit down,”20 King Zhou said. “We’ll eat in just a little while.” He pointed to the cauldron.

“Foolish witchcraft,” King Wen said, glancing contemptuously at the cauldron.

“What have you learned about the sun?” King Zhou asked. Firelight flickered in his eyes.

“The sun is not a god. The sun is yang, and the night is yin. The world proceeds on the balance between yin and yang. Though we cannot control the process, we can predict it.” King Wen took out his bronze sword and drew a yin-yang symbol on the floor, dimly lit by the fire. Then, he carved the sixty-four hexagrams of the I Ching around the symbol, the whole composition resembling a calendar wheel. “My king, this is the code of the universe. With it, I can present your dynasty with an accurate calendar.”

“Ji Chang, I need to know when the next long Stable Era will come.”

“I will forecast it for you right now,” King Wen said. He sat down in the middle of the yin-yang symbol, his legs curled under him. He raised his head to look up at the ceiling of the Great Hall, his gaze seeming to penetrate the thick stones of the pyramid, until it reached the stars. The fingers of his two hands began a series of rapid, complex movements, like components of a calculating machine. In the silence, only the soup in the cauldron in the corner made any noise, boiling and bubbling as though the shaman being cooked within was dream-talking in his sleep.

King Wen stood up in the middle of the yin-yang symbol. With his face still lifted to the ceiling, he said, “Next will be a Chaotic Era lasting forty-one days. Then comes a five-day Stable Era. Thereafter, there will be a twenty-three-day Chaotic Era followed by an eighteen-day Stable Era. Then we’ll have an eight-day Chaotic Era. But when this Chaotic Era is over, my king, the long Stable Era you’ve been waiting for will begin. That Stable Era will last three years and nine months. The climate will be so mild that it will be a golden age.”

“We have to verify your initial predictions first,” King Zhou said, his face expressionless.

Wang heard a loud rumbling from above. A stone slab in the ceiling of the Great Hall slid open, revealing a square opening. Wang shifted his position and saw that the opening led to another tunnel going up through the center of the pyramid. At the end of the tunnel he could see a few twinkling stars.

Game time sped up. Every few seconds in real time, two soldiers flipped over the sandglass brought by King Wen, indicating the passing of eight hours in game time. The opening through the ceiling flickered with random lights, and once in a while a ray of sunlight from the Chaotic Era shot into the Great Hall. Sometimes the light was weak, like moonlight. Sometimes the light was very strong, and the incandescent white square cast against the ground glowed so brightly that the torches in the Great Hall paled in comparison.

Wang continued to count the flipping of the sandglass. By the time it had been flipped 120 times or so, the appearance of the sunlight through the square opening became regular. The first of the predicted Stable Eras had arrived.

After fifteen more flips of the sandglass, the flickering light through the opening became patternless again, the start of another Chaotic Era. Another Stable Era followed, and another Chaotic Era. The starting times and durations of the various eras were not exactly as King Wen had predicted, but they were close. After the conclusion of yet another eight-day Chaotic Era, the long Stable Era he predicted began.

Wang kept counting the flips of the sandglass. Twenty days passed, and the sunlight falling into the Great Hall maintained the precise rhythm. Game time slowed down to normal.

King Zhou nodded at King Wen. “I shall erect a monument for you, one even greater than this palace.”

King Wen bowed deeply. “My king, awaken your dynasty and let it prosper!”

King Zhou stood up on the dais and opened his arms, as though he wanted to embrace the whole world. In a strange, otherworldly voice, he began to chant, “Re-hy-drate…”

As soon as the order was given, everyone in the Great Hall rushed to the door. Wang followed King Wen closely, and they exited the pyramid through the long tunnel they’d entered by. When they emerged, Wang saw the noonday sun bathing the land in warmth. In a passing breeze he seemed to smell the fragrances of spring. Together, King Wen and Wang walked to a nearby lake. The ice over the lake had melted, and sunlight danced between the gentle waves.
