Chang YuChun then went to a large tree by the shore, and dug a hole with his saber. Then he took off all of Little Master Zhou's clothes, before burying him in the ground, and paid his respects. Burying members naked is one of Ming Cult's rules. Everyone enters the world naked, and should therefore leave the world the same way. Since Zhang SanFeng does not know this rule, he found the burial procedure quite repulsive and mysterious.
The next morning, Zhang SanFeng took Zhou ZhiRuo in his hands, and parted with Chang YuChun and Zhang WuJi. After the death of his parents, Zhang SanFeng was like a grandfather to Zhang WuJi. So Zhang WuJi couldn't help but burst into tears as they parted. Zhang SanFeng said, "WuJi, when you're healthy again, your Big Brother Chang will take you back to Wu Dang Mountain. Be a good boy. We'll only be apart for a few months. Don't be so sad." Despite his words, Zhang WuJi's tears did not stop.
Zhou ZhiRuo returned to the boat, took out a handkerchief from her sleeve, and began to wipe away his tears. She then smiled at him, put the handkerchief into his pocket, before returning to shore.
Zhang Wuji followed his grand-teacher with his eyes as the old man walked westwards with Zhou Zhiruo. As the same time, the little girl kept turning back and waving until both of them disappeared behind a row of poplar and willow trees. Suddenly, Zhang Wuji felt so lonely that he started to cry again.
"Brother Zhang, how old are you this year?" asked Chang Yuchun with frown. When the boy answered that he was already twelve, the man said, "I see. A twelve-year-old is no longer a child, so are you not ashamed to sob and cry like a baby? When I was twelve, I had already been beaten several hundred times, but never did I shed a single tear. A man sheds only blood, you know, not tears. If you continue to cry like a girl, I will have to hit you."
"I cried because I could not bear to part with Grand-teacher," said Zhang Wuji. "If someone hit me, I would not cry at all! Go ahead and hit me if you dare. I will return each of your punches with ten punches of my own someday."
Chang Yuchun was stunned. "Good for you!" he said with a hearty laugh. "Now that is what I call a man with integrity. Since you are so formidable, I will not to hit you."
"Why not?" asked Zhang Wuji. "After all, I cannot even move a single finger."
Chang Yuchun laughed again and replied, "If I hit you today, what am I going to do when you eventually learn martial arts from your grand-teacher? How would I be able to endure ten punches from the exquisite fist techniques of the Wudang School?"
A smile appeared on Zhang Wuji's face: This Brother Chang may look very ferocious, but he is not a bad man.
Hiring a riverboat, the two travelled all the way to Hankou before switching to a larger vessel and sailing east down the Great River. The Butterfly Valley where the Healing Sage Hu Qingniu lived was located on the banks of Nüshan Lake in northern Anhui.
The Great River flowed in a south-easterly direction from Hankou to Jiujiang, before turning northwards into the province of Anhui. Two years earlier, Zhang Wuji had sailed up this very river on his way to Mount Wudang. He had his parents and Yu Lianzhou as companions then, so the journey had been filled fun and laughter. Now, his parents were both dead, and he was on a joyless trip to seek treatment with Chang Yuchun. The difference between the two were as stark as the sky above and the land below. But he did not dare to let his tears fall, fearing that Chang Yuchun would be angered again. By then, all the acupoints that Zhang Sanfeng had blocked earlier had returned to normality, so he could actually feel each excruciating attack of the toxins in his body. Yet, there was nothing that he could do, except to grit his teeth in endurance until his upper and lower lips were all cut and bruised. To make things worse, the bouts became more frequent and painful with each passing day.
When they reached the Gua Pier after Jiqing, Chang Yuchun and Zhang Wuji went ashore and travelled north in a hired carriage. Several days later, they arrived in the town of Mingguang, east of Fengyang. Chang Yuchun knew that his Uncle Hu did not like his secluded place of abode to be widely-known, so he sent the carriage away about twenty li (10 km) from Nüshan Lake. Then, carrying Zhang Wuji on his back, he tackled the final leg of the journey on foot.
He thought that these last twenty li would be covered in the blink of an eye, but he had travelled only one li (500 metres) when his nerves and bones started to ache terribly. His breathing became laboured and he found it very difficult to even walk. The internal injuries that he had sustained after being struck twice by the foreign monks were worse than he had realised.
Feeling very apologetic, Zhang Wuji said, "Brother Chang, let me walk on my own. You had better not tire yourself out."
"I can cover a hundred li (50 km) in a single breath without feeling tired at all," Chang Yuchun snapped, "so how could those stupid monks stop me with two strikes of the palm?" Gathering up all his strength, he forced himself to march forward. Unfortunately, he was already too wounded to push himself in this manner, and the frustration that he felt just made things worse. After several zhang or so (1 zhang = 3.33 metres), he began to feel as if his limbs and bones were falling apart. Yet, he was not ready to admit defeat. He was also unwilling to put Zhang Wuji down or to sit and rest. So, he laboured on, a step at the time.
This, of course, made their progress terribly slow. By nightfall, they had not covered even half of the targeted distance. The rugged terrain only served to make the walk more difficult, but they trudged on until they reached some woods. Then, Chang Yuchun finally put Zhang Wuji down and collapsed spread-eagle on the ground. After a simple meal of sugared fruit and biscuits, Chang Yuchun rested for half a shichen (one hour) before voicing his desire to resume the journey. Zhang Wuji tried his best to persuade the man otherwise, suggesting that they could spend a peaceful night in the woods and set out the next morning instead. By and by, Chang Yuchun realised that it would probably be midnight by the time they reached Butterfly Valley. Hu Qingniu would certainly be very irritated by their visit at such an hour, so he gave in to his companion's suggestion to stay in the woods. They soon fell asleep leaning against a large tree.
At midnight, Zhang Wuji was jolted awake by another attack of the toxins in his body. He started to shiver and shake badly, but he endured the pain in silence for fear of waking Chang Yuchun up. Just then, the sounds of clashing weapons drifted into the woods, followed by several voices that shouted, "Where are you going?" "Block the eastern route and force him into the woods!" "We cannot let this crooked baldy get away this time!" Footsteps sounded as several people ran towards the trees.
Waking up with a start, Chang Yuchun grabbed his sabre with his right hand and Zhang Wuji with his left. Then, he waited to see if he should fight or flee.
"I do not think that they have come for us," the boy whispered.
Nodding in agreement, Chang Yuchun peered through the trees and saw seven or eight people attacking an unarmed man from all sides. Although the man managed to fend his enemies off with a pair of swift palms, the group began closing in on him after a while.
