‘ I ’ m so tired , and my legs are aching so much ,’ moaned Wu , as the trio trudged on the dirt path underneath them . For two days , the trio had to wake up early to catch a bus or train , only taking brief naps on uncomfortable vehicle benches , or standing in noisy and crowded stations . The rest of their time was mostly spent on walking , much to the annoyance of the trio . ‘ I ’ m hungry ,’ said Zhu . ‘ You ’ re always hungry ,’ said Wu snidely . ‘ I ’ m just really hungry . I used to have five meals a day , with good food , but now we only have three with awful – ’ ‘ I won ’ t be able to stand this any longer ,’ complained Wu . ‘ Well …’ Jing looked at his phone , and said in a relieved tone , ‘ luckily , we ’ re now in the place Zhang told us to go to .’ The trio arrived at a village . Children ran past them as the adults stared at the newcomers , who stopped at a small house - the address that Zhang gave them . ‘ I hope Old Monk will to give us something valuable ,’ Wu said as Jing knocked on the door . However , there was no reply . Jing knocked again , and shrugged . ‘ Maybe we should just go inside ,’ Zhu suggested . They walked into the house and found themselves in an empty room , devoid of any sort of furniture . ‘ After all we ’ ve traveled , is this our destination ? ’ Wu asked incredulously . ‘ Have we gone to a wrong place ?’ ‘ Old Monk made us come here for nothing !’ groaned Zhu , ‘ Where ’ s the valuable thing he said he ’ d give us ?’ ‘ Um , Old Monk didn ’ t force us to come here . We did so on our own accord ,’ said Jing , ‘ The whole place is empty ! Perhaps we should head back home ,’ Wu said in an annoyed tone . But then she took a deep breath , and suggested , ‘ Let ’ s check the whole house first .’ Wu tried to pry open the floorboards to see if there were any trapdoors or hiding places that could indicate their old professor ’ s location . ‘ I don ’ t think you should do that , Wu . You ’ re damaging …’ said Jing . Wu frowned , but started tapping on the floorboards . Zhu put his bag on the floor and prepared to sit on it , but got up and inspected the house with Wu instead . However , nothing important could be found . Disappointment was shown all over their faces . The group was silent for a few minutes . Then , Zhu said miserably , ‘ Now we should return home . Who cares about Old Monk ?’ Wu walked over to the side of the house and looked out of the window . Did all of their effort go down the drain ? Did they really gain nothing from this long , uncomfortable and exhausting journey ? Should they just head back and call it a day ? But something in Wu ’ s mind made her speak , ‘ I think we should wait here . That ’ s what we ’ ve promised Old Monk .’ ‘ Wu ’ s right ,’ said Jing . ‘ Well , yeah , he ’ s our old professor after all ,’ said Zhu , ‘ We shouldn ’ t mind waiting for a little longer . Why don ’ t we have catch up on our lives ?’
