When the boat reached the mouth of the Yangtze River, Li Zhi looked at the beautiful scenery of pear blossoms reflected in the spring water and sighed: "People in the south are eating lychees, but the pear blossoms in the south have not yet withered. Does the steward know the reason?"

Wang Zheng pondered for a long time. At first, Li Zhi waited patiently. Just when Li Zhi wanted to change the subject, Wang Zheng said slowly, "I have a guess, but it's a bit shocking."

Li Zhi said with a surprised look on his face: "The chief steward often does surprising things, but he always manages to be calm and composed. If even the chief steward finds it shocking, then he must be really extraordinary. Tell me about it, so that I can be surprised too."

Wang Zheng pointed to the sea and asked Li Zhi, "Your Majesty, do you think this vast expanse of blue water is flat?"

Li Zhi narrowed his eyes, thought for a while, and said, "This sea must look flat, but since the steward asked this, then it must not be flat. Can the steward prove it to me?"

Over the years, Li Zhi has become accustomed to Wang Zheng's magic. As long as there is evidence, Li Zhi is willing to believe everything. After all, Fei Tian has done it, so what else is impossible? Even if he doesn't fly very high, he is still Fei Tian.

Wang Zheng pondered for a moment, and let a boat sail south alone. Then he returned to the dock with Li Zhi and others and watched the boat with a telescope. The boat went farther and farther away, and slowly the hull sank, leaving only the sail.

"Because the sun rises in the east and sets in the west, the earth must have north and south poles. The poles are the coldest, while the middle is the hottest. Whether it is true or not, the third brother will definitely give your majesty an answer in the near future."

Wang Zheng smiled and said, "If the earth is a sphere, many things can be explained. If my prediction is correct, it will gradually get colder as we continue to head south."

"There is a quick way to achieve success. For example, I have cleansed the minds of Lü Yan and Qingxu Zi before, and the effect was quite good."

Li Zhi pondered for a moment, then asked with a strange look on his face, "The steward has been sending money to Chang'an over the years. Is this also to cleanse the hearts of me and the queen?"

"hey-hey."

Li Zhi was naturally aware of these things.

Li Zhi nodded and smiled, "With the heart of a saint, creating this prosperous world can achieve twice the result with half the effort, but the life of the chief steward is a little too dull."

Wang Zheng asked people to find black and white cloth, tied them to bamboo poles at intervals, and erected them on the shore to make a very eye-catching sign. Then he and Li Zhi went out to sea on a boat.

The other little guys were all laughing.

Wang Zhen bowed to Li Zhi and said, "I will find the answer for your majesty as soon as possible."

Wang Zheng smiled and said, "Saints are actually very boring. It's so nice to be thirty thousand miles away from the mortal world."

When Lu Dongbin and Qingxuzi first arrived in Yuzhou and took charge of the Taoist temple, they were a little lost. Wang Zheng not only did not correct them, but did the opposite and kept sending them wine, meat, women, gold, silver and treasures.

Li Zhi nodded, then sighed and asked Wang Zheng, "Since the chief steward believes that the earth is a sphere, what does this have to do with the north and south climates?"

The lofty Dao is beyond reach, and I am not a saint after all."

The master was annoyed by the fourth senior sister's nagging, so he promised her to the third senior brother. However, the master would not force the fourth senior sister, and let the third senior brother try hard on his own. Unfortunately, the third senior brother seemed incapable of doing so.

Looking back at the shore half an hour later, only four of the five white cloths could be seen. After sailing for another half an hour, only three of the five white cloths could be seen.

Li Zhi looked at Wang Zhen and said, "After this trip to the Northeast, come back as soon as possible, whether it succeeds or not."

Li Zhi thought for a moment and said, "I feel that the world has changed so much, time has passed, and I feel like nothing matters anymore. How insignificant people are. It's only been a few days, and I've already lost myself. The steward is always immersed in this state of mind, no wonder he sees through everything.

Wang Zhen pulled the corner of his mouth, his face full of helplessness, "I obey your order."

The boat went back and forth, wasting a lot of time. In the end, it could only rest in Jiangnan for a day before setting off again.

"I'm afraid this state of mind is difficult to achieve, right?"

Li Zhi put down the telescope and was silent for a long time. He then said to Wang Zheng, "Is the sea always flowing far away?"

Wang Zheng smiled and said, "If the sky has feelings, it will also grow old. There are countless mundane affairs. If I bring my own preferences and emotions with me, I'm afraid it will be difficult to sort them out. Only by abandoning myself from the mundane world and looking at the world with a cold eye can I grasp it more accurately."

Wang Zhengyun shook his head calmly and said with a smile: "I don't know either. I just think this is amazing and want to share it with Your Majesty. After I observe it for a few more days and have more evidence, I will tell Your Majesty the answer."

The little guys looked at each other, Wang Zhen seemed to be thinking about something, Li Zhi's smile was very forced, and finally he fell silent. After a long time, he asked Wang Zheng: "Do you want to tell me that the sky is round and the earth is round?"

During the rest of the journey, Li Zhi became more and more silent, and would stare blankly at the sea and the sky from time to time.

Li Zhi was silent for a long time and then said, "There is a sea to the east of Fusang, there is a sea to the south of Lingnan, there is a sea to the south of Tianzhu, and it is said that there is also a sea in the far west. There are seas everywhere in the world, but what is in the depths of this sea?"

After a few days, Wang Zhengcai said to Li Zhi: "Your Majesty, you don't need to think too much. Just wait for the answer."

Li Zhi was stunned and asked, "Why is this?"

Li Zhi smiled bitterly and said, "The steward has really done a lot of harm to me. I don't have a smart mind, so I can only think about these things, but I have understood the steward's state of mind."

As a result, within two months, the two guys had completely lost interest in the mundane world and devoted themselves to research, wanting to find out the truth about this world.

Wang Zheng pondered for a moment and said, "Whether it is true or not, we will know if we look back from the far sea."

Wang Zheng did not comment, but smiled and asked, "What do you think, Your Majesty?"

Li Zhi laughed loudly and said, "Haha, my worldly desire and lust for power are not so easy to wash away. Although the steward has a lot of money, it is not unlimited. I am afraid that the steward will be disappointed."

Wang Zheng smiled and said, "I can't say I'm disappointed. After all, the money made His Majesty and His Majesty happy, right? And if His Majesty is in a better mood all year round, the people in the palace and the ministers will also have a more relaxed life.

Then the lives of the people in Chang'an will be better. After all, smiles and good moods are contagious, and the contagiousness of your majesty and your majesty is beyond doubt."

Li Zhi thought about it and nodded, "If the steward said so, it does make sense. In recent years, I have seen that the people in Chang'an City are indeed smiling more. I didn't expect that the source is still me."
