Zhang Yongchang only turned back to the kitchen after sending Zhuang Qingning out of the backyard. He bellowed for Lian Rong, "Hurry, prepare some large bones for me. I want to try cooking them while I still have the time to see how it will turn out."
Having finally got the recipe, it didn't make sense to set it aside.
Any task should be completed promptly—that was always for the best.
Zhang Yongchang indeed disliked procrastination.
Even though Lian Rong was busy, he had overheard the conversation between Zhang Yongchang and Zhuang Qingning and understood what was going on. Upon hearing Zhang Yongchang's request for large bones, he briskly agreed and promptly went to gather them.
And he was thrilled.
Since Zhang Yongchang was his master, if the master was happy, so was he.
