Ah Dai looked down the chasm, only able to see dim yellow light below, suggesting a deep passageway. The ground that had just split open was covered by three-foot-thick steel plates, beneath which lay numerous small holes on either side. Ah Dai, familiar with Goris' designs, knew that if the proper method to activate the mechanism was not found, a forceful entry would result in severe damage. Moreover, nothing would be gained as the traps set by Master Goris were always secure.
Ah Dai's trust in Goris made him proceed fearlessly and with no hesitation. Carrying the letter in his hand, he hurriedly descended. When he had descended ten steps, a rustling sound rang again. Ah Dai looked up, and the chasm had inexplicably closed itself to appear solid once more. Looking under his feet, he realized that the trapping mechanism was most likely in this tenth step.
