The three people who were still enjoying the cool breeze in the courtyard saw the old man approaching from the side room and only then turned their gaze away, pretending to continue their chatter and bragging as if they didn't know anything. However, they were all secretly pondering in their hearts.

The next day, Mu Yu woke up early and as soon as he stepped out of his room, he saw a table of four people leisurely drinking tea.

Upon hearing the sound of footsteps, Zhang the Master turned his head and greeted, "Little disciple, come over here and have a cup of tea with old man."

Mu Yu said, "Good morning," and then walked over to the spot pointed by Zhang Tian Shi and sat down.

"The Cheng brothers also greeted him, with a relationship that was neither too intimate nor too distant, just right."

Li Mingyue poured him a cup of tea, but his expression was not as enthusiastic as it had been yesterday.

Mu Yu felt as if they all knew something last night, but regardless of whether or not they did, he had no choice but to act as though nothing happened and not mention anything about Teng Yi. He was afraid of encountering another Qingfeng Daoist.

The atmosphere among the people was a bit awkward, but Zhang Tianshi didn't pay much attention to it. He directly took out several books and said, "Hey, disciple, keep these books first. Read them all within a month, and you will experience what it's like to follow this old man around during this month."

Muyu took the roughly written book and glanced at it, realizing that it was nothing more than some Taoist classics and the Tao Te Ching.

Master Zhang took a sip of tea and patted Mu Yu's shoulder before making a grand gesture and saying, "Let's go! Old man, I'll take you to breakfast, and then we'll go hang out at the teahouse for a while!"

For two consecutive days, Mu Yu followed Master Zhang around the city, drinking Tie Guan Yin tea and eating the signature dishes of various restaurants. Life was quite comfortable.

As soon as the two returned to the house, Li Mingyue handed a letter to Zhang Tianshi.

"Master Zhang looked at the address and name, then smiled and let out a chuckle. He tore open the envelope and pulled out two pages of paper, which he read twice before folding them back up."

Mu Yu felt strange looking at Zhang Tianshi's appearance and asked, "Sir, have you encountered something good?"

"Master Zhang smiled and shook his head. 'A friend of mine wrote to me, saying that he had returned home. This person is also very capable. One of these days, I'll take you to meet him and see if he thinks highly of you.'"

After finishing speaking, Master Zhang let out a sigh and said, "It's been so many years since I've heard from him. Has he found what he was looking for? He came back and immediately sent me a letter, not letting me down for keeping a bottle of old wine for him."

Li Mingyue was particularly delighted upon receiving the letter as it was from his own master's friend. In the past, this person had taken great care of Li and his two brothers, often giving them guidance and advice. They were almost like a second master to them.

Li Mingyue said again, "Master, someone from the teahouse has sent a message, saying that someone called to report that there's been an incident in the tunnel in this province. They're asking you to go and help resolve the situation."

Master Zhang's joy on his face receded and he suddenly became serious, asking, "A tunnel? Where did this message come from? Was it a request for my help or was it a summons for me to go?"

Li Mingyue stepped forward and whispered something into Master Zhang's ear. Without hesitation, Master Zhang instructed Mu Yu, "Go back to your room and grab some clothes. Wear more layers, we have an important matter to attend to together."

Li Mingyue frowned and said, "Master, where are Second Junior Brother and Third Junior Brother? Shall I go and fetch them?"

Zhang Tianshi waved his hand and said, "No need, the three of us can go alone. Those two kids are always sticking together, it makes me feel nauseous."

Mu Yu didn't understand what Zhang Tian Shi meant by "getting tired of each other". However, in the near future, he will come to understand the true meaning behind these words.

After half an hour, the three of them each tidied up and Zhang the Master put on a slightly old Zhongshan suit. He led the other two and took a few hours of bus rides, followed by half a day's train journey. It took a full ten hours for them to arrive at the place mentioned over the phone.

"At this moment, it was already late into the night."

Master Zhang looked at his watch and casually picked up a cigarette stick. He knocked it against the street lamp post, producing a crisp sound that was metallic in nature.

"It's already ten o'clock. Let's first find a place to stay and grab something to eat. The tunnel is less than two kilometers away from here. We can go over there when it's light outside."

Mu Yu blew the wind and gathered his collar. As a follower, he naturally obeyed Zhang Tian Shi's arrangements. Also, he didn't know whether it was because of the enclosed space of the train, but it was very stuffy. When they got off the train, the evening breeze blew suddenly and the chill seeped into his heart.

Li Mingyue noticed Mu Yu's slight movements and lightly patted his shoulder, saying, "You seem a bit weak. It's good to exercise more in the morning, which can increase your resistance."

At some unknown point in time, Zhang Tianshi had already taken a few steps and walked quite far ahead. The two people behind him looked at each other and quickly followed.

For dinner that night, Zhang Tianshi cooked grilled and braised meat with a side of beer, consistent with his usual style of indulgence. They ate and drank in abundance, so much so that one could mistake them for a group of prisoners who had just been released from their cells.

The landlady saw their behavior and only dared to leave after they finished eating and paid their bill, afraid of encountering people who would eat without paying.

After finishing their meal, they checked into a hotel, took a shower, and slept for one night. Mu Yu slept until Li Mingyue came knocking on the door to wake her up.

"Knock! Knock! Knock!"

Mu Yu flipped over and got up. She quickly put on her clothes and at an extremely fast pace, washed up and tidied her messy hair while Li Mingyue knocked on the door for the second time. When Mu Yu directly pulled open the door, she appeared inside with a neat and tidy appearance.

Li Mingyue lowered his head and looked at the two silly-looking wisps of hair on Mu Yu's head, and couldn't help feeling a little better. "Master has just woken up, let's grab something to eat downstairs for breakfast and then leave."

"Ah?" Mu Yu responded before realizing that her tone was not right. She quickly added, "Okay! Right away!"

Muyu turned around and grabbed her backpack, then lifted the pillow and stuffed the dragon seal hidden beneath it into the pocket of her jacket.

As soon as he came downstairs, he saw that Zhang Tianshi was particularly refined while eating small soup dumplings. He was wondering why Zhang Tian Shi's table manners had improved when he noticed that there were two empty steaming baskets on the table. So, it turned out that Zhang Tian Shi had already eaten two portions!

Compared to Mu Yu's stunned expression, Li Mingyue seemed unsurprised. He turned around and called for three more baskets of small soup dumplings.

Master Zhang took a small bite of the soup dumpling, savoring the delicious broth and letting out a contented sigh. If it weren't for the two empty spots in front of him, Mu Yu would have been fooled by this old guy.

Mu Yu rolled her eyes inwardly, picked up a pair of chopsticks, and took a bite of the soup dumpling. At that moment, Zhang Tian-shi spoke up: "Mu Yu, let me tell you, when it comes to eating, you need to be fast, accurate, and fierce. Any hesitation..."

Zhang Tianshi spoke seriously to Mu Yu for a long time, with strong arguments and evidence that were convincing, demonstrating his skill in deceiving people.

Muyu was dumbfounded by the deception, and he didn't even realize when the bamboo steamer in front of him had become empty.

Looking at Master Zhang, he picked up the final soup dumpling with his chopsticks and put it in his mouth. Then, he patted the young man on the shoulder and said, "Young man, don't just believe everything you hear. You'll only end up getting hurt in the end."

After speaking, Master Zhang patted his stomach, lit a cigarette, took a drag and went to wait for the both of them at the hotel entrance.

Li Mingyue shook his head and whispered to Mu Yu, "Don't chat with him during mealtime. He's a sly old man who only knows how to trick others into treating him to food and drinks. He's nothing but a dishonest and unreliable person."

"Ten o'clock in the morning."

Three people strolled leisurely to the construction site. Just as they approached the erected tents, a person wearing a safety hat and a blue work uniform came out. Despite his attire, he had not a speck of dirt on him. He appeared to be either an engineer or a foreman.
