Zhu Ying replied, "I only got to know more about His Royal Highness Prince Yu today."

“Never heard of it before.”

Liu Rixin nodded. He had only known about His Royal Highness Prince Yu in the past few days.

Because Zhu Xiongying had always been in the deep palace, and his academic training was not the same as other princes and grandchildren, but a famous scholar invited by Zhu Yuanzhang alone.

Even Zhu Yuanzhang and Empress Ma taught personally.

After he died at the age of eight, there were few rumors outside except those within the palace.

In particular, Zhu Xiongying's early death caused Empress Ma to be so grief-stricken that she passed away.

Even the princes and grandchildren of the emperor did not dare to mention it easily in front of Zhu Yuanzhang.

Zhu Xiongying was such a favorite, but there are only two short sentences recording him in the entire Ming history.

Because the naming rules that Zhu Yuanzhang set for his many sons were very popular.

In order to avoid taboos and not affect people's livelihood, the princes' hereditary system has a large number of uncommon characters.

This also led to the fact that when later generations heard the name Zhu Xiongying, they would subconsciously feel that they would not agree with it.

This is also the reason why Zhu Ying initially felt very unfamiliar with Zhu Xiongying's existence.

As Zhu Ying and Liu Rixin's conversation became more in-depth.

Liu Rixin was more and more shocked.

It was not because of his unexplained identity, but more because of some of Zhu Ying's insights and those unique insights that made Liu Rixin suddenly enlightened.

When the two talked about metaphysics.

Zhu Ying put forward his own views.

People in later generations are relatively interested in metaphysics. Zhu Ying had also looked up information about it and even relied on the relationship with his father in his previous life to briefly study with a Feng Shui master.

The Feng Shui of later generations has changed a lot compared to that of the Ming Dynasty.

The main reason for this is the impact of scientific and technological development, which has allowed the knowledge of Feng Shui to be more integrated.

Regarding the discussion on Feng Shui with Liu Rixin, Zhu Ying directly put forward the concept of geomagnetism.

"During the Song Dynasty, Shen Cunzhong, the father-in-law of Mengxi, talked about geomagnetism in his 'Mengxi Bitan'." Liu Rixin replied. As a fortune teller, he was well-read and was also deeply impressed by the statements about geomagnetism.

Zhu Ying was a little surprised to hear Liu Rixin's answer. He originally thought that he would have to waste a lot of time and effort explaining before Liu Rixin would understand.

In his impression, the concept of geomagnetism seemed to have been discovered in the West, but he did not expect that it already existed in the Song Dynasty.

It is only because of the limitations of thinking and the threshold of reading that not many people know about it.

After organizing his words slightly, Zhu Ying skipped the topic and said:

"In my opinion, there is a huge magnetic field between heaven and earth, and within this magnetic field, there are many properties."

"The yang energy, yin energy, evil energy, blessing energy, bad luck, etc. in Taoist doctrines are all included in this magnetic field."

"The names are different, but there is no difference in essence. Sir, you just mentioned the aura of the mountains, and that is the same."

"The characteristics of these magnetic fields can be divided into two types: good and bad. The so-called Feng Shui treasure land is a place where the magnetism is very strong due to the special environment."

"These magnetisms are all very good. The remains of our ancestors buried here have been influenced by magnetism for a long time, and even the remains themselves contain a lot of good magnetism."

Hearing Zhu Ying's story, it seemed as if a new door had been opened for Liu Rixin. New knowledge appeared in front of Liu Rixin, and the impact was very strong.

Although Zhu Ying's explanation was simple, even some less educated officials of the Imperial Observatory were a little confused.

But Liu Rixin himself has reached a peak in metaphysics, or even a bottleneck.

In just a few sentences, it was like an epiphany, and I saw a new world.

After a moment's silence, Liu Rixin asked respectfully, "I have one question that I don't understand. According to Master Zhu, how can the bones of our ancestors be nourished by this magnetism and benefit future generations?"

Zhu Ying replied: "The greatest connection between ancestors and descendants is blood."

After thinking for a while, Zhu Ying explained: "I think blood is not just in the flesh and blood, but also in the hair, bones and even the breath."

"The bones of our ancestors are nourished by the magnetic field, and the magnetism becomes stronger and stronger, spreading throughout the heaven and earth, and begins to connect with the descendants who have the same magnetism. The descendants are blessed with many fortunes and good fortunes, and they are blessed with good health. That's how it is."

After hearing these words, thousands of inspirations began to collide in Liu Rixin's mind, producing brilliant sparks.

Zhu Ying didn't speak for long, but Liu Rixin could feel that there was definitely a complete explanation for the concept of magnetic field.

It is impossible to explain such a profound and simple truth with just a concept.

Metaphysics itself is obscure and profound. During Liu Rixin's years of research and study, he also encountered many puzzles that were difficult to solve.

After hearing Zhu Ying's words today, I felt as if a light bulb had suddenly appeared on my head, and all my confusions seemed to have been solved.

If I hear the truth in the morning, I can die in the evening.

Now Liu Rixin suddenly feels unwilling to die.

The Tao is right in front of us, within reach. To die like this would be to die with regrets.

He suddenly wanted to plead with His Majesty to give him more time after the mausoleum incident, even if it meant imprisonment, so that he could study these principles clearly and write a book to pass them down.

Suppressing his excitement, Liu Rixin took advantage of the brief exchange and asked Zhu Ying hastily:

"What Master Zhu said was all about geography. I wonder how this magnetic field is related to the celestial astrology."

Liu Rixin is proficient in Zi Wei Dou Shu and has knowledge of astronomy and geography.

Hearing this, Zhu Ying smiled slightly and said, "I wonder if you have ever been to Qiantang River to watch the tides."

"The moon waxes and wanes, and every time the moon is full, the high tides on the Qiantang River are affected by the moon's magnetic field."

Liu Rixin was so inspired that he said, "The stars in the sky are just like the earth, they all have magnetic fields."

"This magnetic field encompasses everything in the world."

Zhu Ying nodded and said affirmatively: "Of course it is so."

Zhu Ying, who came from later generations, was extremely clear about magnetic fields and spoke with great confidence.

Liu Rixin suddenly understood, and some long-standing confusions disappeared.

Different from the Western geocentric theory and heliocentric theory.

The ancient Eastern concept of the round sky and square earth is not a specific concept like the flat earth theory, but a philosophical idea and a manifestation of the Yin-Yang theory.

The sky and the circle symbolize movement, while the earth and the square symbolize stillness. The combination of the two represents the balance of yin and yang, and the complementarity of movement and stillness.

Therefore, the concept of magnetic field was easily accepted by Liu Rixin.

Liu Rixin was about to ask more questions when an official from the Imperial Observatory came over and reminded him, "Sir, the time has come."

It is already noon at this moment.

At the tomb of King Yu, there were already hundreds of Xiaoling Guards guarding it, and three thousand civilians on standby.

Just wait until 15:30, when the Yang energy is at its peak, and start digging.

The excavation process involved dense underground rivers, and Liu Rixin and officials from the Imperial Observatory needed to supervise the entire process to avoid mistakes and collapse.

At this moment, Liu Rixin was no longer interested in Zhu Xiongying's identity, but was more concerned about Zhu Ying's profound knowledge.

However, the time had come and he could not disobey, so he could only say goodbye reluctantly and leave with a group of officials from the Imperial Observatory.

Zhu Yuanzhang would naturally not arrange for his eldest grandson to do such work as digging graves.

Now Zhu Ying also thought that it was just an ordinary sacrifice, and he didn't know that there were thousands of people in the back mountain waiting to dig the tomb.

Eunuch Zhang looked at the Jinyiwei who were guarding outside the temple without making any movement.

After a slight hesitation, he turned to Zhu Ying and asked, "Mr. Zhu, do you have time to go with me to the Queen Mother to pay tribute to her?"

"Your Excellency, I am truly honored. It would be my honor to be able to pay tribute to the Empress."

Zhu Ying said politely. He felt flattered when he heard Eunuch Zhang call himself an old servant.

Before the Eastern Han Dynasty, officials generally referred to people who worked in the imperial palace, including not only eunuchs but also scholars.

During the Yuan Dynasty, eunuchs referred to second-level officials.

It was not until the Ming Dynasty that eunuchs and eunuchs were confused.

Although Zhu Yuanzhang strictly prohibited eunuchs from interfering in government affairs, the status of eunuchs was still relatively high because they worked in the inner palace.

Eunuch is an elegant name used by ordinary people to refer to eunuchs.

Generally, eunuchs call themselves "Zanjia", "Sajia" or "Zajia" because of the differences in dialects.

In the middle and late Ming Dynasty, eunuchs had great power in the court and even called themselves "Masters".

Only those of high status would do so. The lower eunuchs usually called themselves slaves.

People like Eunuch Zhang who call themselves old slaves will only target members of the royal family.

"Mr. Zhu, there is no need to say more. Just follow me."

Eunuch Zhang raised his hand slightly, then put it down again. He subconsciously wanted to pull Zhu Ying's sleeve, but felt that it was not respectful, so he gave up.

From initially calling himself Your Highness, he now calls himself an old slave.

It was obvious that Eunuch Zhang, who had lived in Xiaoling Mausoleum for a long time, was isolated from the world, and when he saw that he was personally accompanied by the Jinyiwei pacification envoy, he had a deep misunderstanding.

Zhu Ying had no choice but to bow and say:

"Thank you very much, sir."
