What episode does the old fart eat pie in the big house die of?

In the TV series "Da Zhai Men", the old fart ate a big cake and died in 55 episodes.

At first, after knowing the identity of Bai Jingqi, Zheng Laofart had a glimmer of hope except fear, hoping to make friends with Bai Jingqi. So he took his native products to visit Dazhaimen, claiming to be Bai's friend. Facing the food prepared by Bai Jingqi for him, Lao fart was restrained at first, and then he let go of his stomach to eat. But when he found that he could win the pleasure of the young ladies and gentlemen in the big house, this kind of eating was no longer eating, but a performance.

When Zheng Lao fart heard that Seventh Master had been released, he immediately dragged his sick body back. He also brought his grandson to let Seventh Master have a good meal. Qi Jing was very happy when he heard that Zheng Lao fart was back, and offered to see him eat big rolls of meat. Zheng Laofart is still ill, and there is a famine in his hometown. He hasn't eaten for two or three days. He ate two pounds of pie meat at once and was exhausted.
