The creation of a literary work needed to go through many stages, including conception, writing, revision, and so on. The following is the outline of a literary work: Story background: In ancient China, there was a man named Chen Sheng. He led his team on the grasslands and encountered a mysterious cave. Strange sounds came from inside. After Chen Sheng and the others entered the cave, they found a huge stone hidden in the cave with strange symbols carved on it. Story summary: Chen Sheng and the others decided the importance of this stone and brought it back to the city. After returning home, Chen Sheng handed the stone to the local officials, hoping to get some benefits. The officials attached great importance to this stone and decided to present it to the emperor. In front of the emperor, the officials gave a detailed introduction to this stone, and the emperor was also attracted by the extraordinary splendor emitted by this stone. Therefore, the emperor decided to name it the "Heavenly Gem" to protect the country's safety. However, as time passed, some problems began to appear with this stone. Its light became dimmer and dimmer, gradually losing its original color and light. Chen Sheng and the others also began to feel uneasy. They thought that this stone might have become an ordinary stone. Story Ending: In the end, Chen Sheng and the others decided to find the truth about this stone. After an arduous search, they finally found a place called the Crystal Palace, where a stone very similar to the Celestial Gem was hidden. After careful observation, they found that this stone was made of three different stones that had undergone complicated processing and polishing. They were red agate, sapphire, and jade. After this experience, Chen Sheng and the others finally understood the truth of this stone. They also told the story of the Celestial Gem and the three kinds of stones to future generations, hoping that more people would understand and cherish these precious treasures.
