People in the Qin Dynasty, entertained during the Warring States period

Cao Ze suddenly remembered that five months ago was the time when he killed Shen Leping.

He stroked the dark side of the bamboo slip; it was indeed a burn mark.

At that time, Brother Cheng used kerosene to set fire to Luo Wang's stronghold, and everything matched up.

This letter was indeed recorded by Shen Leping.

Cao Ze put the bamboo slips back, left the archives, exited the Zhao King's Palace, and strolled through the somewhat deserted inner city of Handan.

If the bamboo slips only recorded anecdotes and stories about Duke Zhuang of Zheng, he wouldn't have thought so much about it.

He never expected that these letters were actually written by Shen Leping.

According to the description in the book.

The mausoleum of Duke Zhuang of Zheng may hold a mysterious treasure, containing the secrets of his rise to power.

That's fine then.

But Shen Leping clearly knew something, saying that among the treasures of Duke Zhuang of Zheng was a magical mask that could transform into any appearance he had ever seen, and even simulate and transform his aura.

Cao Ze immediately thought of the mask worn by the black jade unicorn.

Wei Zhuang has not yet become the director of the Liusha Zoo.

The Jade Kirin has not yet appeared.

If I'm not mistaken, the mysterious place Han Fei entered with Ni Lin in the original trailer, the unknown lost city, is the mausoleum of Duke Zhuang of Zheng, which he built on a grand scale.

The mask was obtained inside and eventually ended up in Wei Zhuang's hands.

To verify this, we'll have to make a trip there.

Whether it's a mask or not is unimportant; he's simply very interested in the secret of the Azure Dragon Seven Mansions that Han Fei discovered.

Cao Ze felt a pang of regret; he wished he hadn't been so swift and decisive in killing Shen Leping.

They should first use severe torture to extract a confession, subjecting the suspect to heavy-handed torture.

Cao Ze arrived at the Lecture Room as promised.

We're nearing the end of our course on fundamental physics.

It mainly covers elementary school natural science, interspersed with some middle school knowledge.

It focuses on describing phenomena and summarizing patterns, and is not so abstract.

It's not as hardcore and brain-teasing as the logic we started with.

Therefore, apart from those eagerly awaiting the novel, there were quite a few disciples from various schools attending the lectures.

Cao Ze gave a brief conclusion to the physics section.

After finishing the first half of the eighty-eighth chapter of Journey to the West, he said, "Over the next three days, I will summarize the knowledge I have learned during this period. After that, I will begin to teach the next subject—chemistry."

"Mr. Cao Ze, what is chemistry?"

Cao Ze laughed and said, "If physics, as Zhuangzi said, is about 'analyzing the principles of all things and judging the beauty of heaven and earth,' then chemistry is about 'describing the changes in the world.'"

The disciples from all schools looked at each other, then asked, "Sir, could you give an example?"

Because Cao Ze often utters the phrase "Let me give you an example" when he gives lectures, it has now become a common saying among the disciples of the Hundred Schools of Thought when exchanging knowledge.

Cao Ze paused for a moment, "Have you ever heard of turning stone into gold? Chemistry is about how to turn stones into gold."

Upon hearing Cao Ze's words, everyone's eyes lit up.

Cao Ze smiled faintly and retorted, "I know what you're thinking, but I can tell you that it is indeed possible to turn a stone into gold, but the cost would be more than a mountain of gold."

Compared to 'turning lead into gold', he felt that the possibility of hand-crafting nuclear bombs was more likely.

Everyone was speechless, looking at Cao Ze with resentment.

No wonder he talks about it; it's all theory again.

Chapter 179 Guo Kai, you don't want to lose your position as prime minister either, do you?

A knowledgeable Taoist disciple raised his voice and said, "Master, you said that chemistry is the science that describes the changes of all things. I once saw a kind of 'Nine Springs Gold' in an ancient Taoist text, which means 'gold that dissipates in the nine springs.'"

"This substance dissolves and becomes invisible when it comes into contact with water, and it releases flammable gas that will ignite upon contact with fire. Its appearance is no different from ordinary gold."

"Sir, do you know what this principle is?"

Cao Ze paused for a moment. Was this a test for him?

He certainly knew that there was a substance called metallic sodium that could achieve such an effect.

However, it is clear that this Jiuquan gold only has properties similar to metallic sodium, but it is somewhat different from metallic sodium.

"I have never seen the Nine Springs Gold with my own eyes, but I do know of something that can achieve the effect you described. I will tell you about it in the upcoming lecture."

It was virtually impossible to produce metallic sodium in ancient times.

However, in this somewhat mystical world, it shouldn't be difficult for him to use lightning magic to control the voltage and extract a little metallic sodium.

After dealing with the disciples of the Hundred Schools, Cao Ze leisurely left the Hundred Schools Lecture Hall.

Since Gongsun Long went into seclusion, and representatives of various schools of thought such as Daoist Mu Xuzi and Confucian Fu Nian left, he is now recognized as the most prominent figure on the Hundred Schools Forum.

If he weren't so young and hadn't been famous for so short a time, his current reputation and status would at least be at the level of a leader of a hundred schools of thought.

It was already late at night when Cao Ze returned to Qingping Residence.

What puzzled Cao Ze was that at this time of day, Li Wu would usually drag him off to have fun as soon as she saw him return.

but now……

Seeing Cao Ze seemingly absent-minded and pacing back and forth in the courtyard, muttering to himself, Li Wu was greatly alarmed.

Is he possessed by a ghost?

Cao Ze dared not wake Li Wu, so he quickly pulled Jing Ni, who was taking care of the child, out of the house.

Jingni glanced at it and said, "It's nothing."

Cao Ze pointed at Li Wu, who was almost sleepwalking, and said, "You call this okay?"

Jingni blinked her gentle eyes and said confidently, "It's nothing. She's trying to build a large internal circulation."

"Huh? You mean she's cultivating?"

Jingni said, "Yes, she has entered a state of enlightenment."

This was the first time Cao Ze had ever seen someone have such an epiphany.

"This……"

Jingni, holding Xiaoyan'er, said, "Look at her breathing and her footwork, isn't it very methodical?"

Cao Ze smacked his lips. "Is this how you guys in the Luo Wang organization break through?"

Jing Ni rolled her eyes at Cao Ze and said, "Wasn't this all taught to you?"

Cao Ze asked in surprise, "I taught you? When did I teach you?"

"Uh, could this be the Heavenly Gang Step?"

Cao Ze realized that he had indeed taught Li Wu a footwork technique.

So that fragile mages won't be unable to position themselves properly.

Jingni said, "That's right. Li Wu has made some minor changes in the past few months and has comprehended the Heavenly Gang Great Circulation Method."

Cao Ze's smile was somewhat strange. This was a minor modification? It was a major overhaul!

When Li Wu was "picked up" by Cao Ze, she had already opened up ten proper channels.

Having followed Cao Ze for more than half a year, aside from partying at night, he devoted almost all his time to cultivation, working even harder than Jing Ni, and successfully opened up all twelve meridians before the New Year.

Not long ago, he also cleared all the meridians in his body.

Of course, all of this was inseparable from Cao Ze's teachings on cultivation methods and Jing Ni's one-on-one guidance.

Otherwise, it would take her at least two years to have any hope of establishing the Great Circulation within her body.

Cao Ze watched as Li Wu, who had been sleepwalking, finally stopped wandering around the courtyard and sat down cross-legged with her palms facing upwards. He breathed a slight sigh of relief.

I'm really afraid that the concubine I just took in will be sent away before she even gives birth.

"Is she confident she can break through?"

Cao Ze asked Jing Ni.

Building the Great Circulation within the body is different from opening the Eight Extraordinary Meridians and building the Small Circulation within the body.

To establish the microcosmic orbit, one only needs to open up the Du and Ren meridians, integrate the Yin and Yang energies within them, and allow them to flow smoothly through the eight extraordinary meridians; this is considered a success.

To build the Great Circulation, it is not only necessary to open up the twelve regular meridians and then unblock all the meridians in the body, but also to continuously use internal energy to circulate throughout the body and carry out the Great Circulation of the meridians.

In this process, the spirit and qi will closely unite and become inseparable, cultivating a breath of innate qi.

Only in this way can the Great Circulation be stabilized, returning from the acquired to the innate, and entering the realm of the first-class.

Jingni said, "I think so, she told me."

Cao Zeman hopes that Li Wu can make a breakthrough.

Compared to second-rate masters, first-rate masters represent a qualitative leap.

Whether it's internal strength or physical fitness, there are almost no weaknesses.

In the martial arts world, he is the kind of person who deserves a title.

For example, there's the nameless swordsman, the chivalrous Tian Guang, and the adorable tiger in the field.

This signifies that one's strength has been recognized by people in the martial arts world.

Cao Ze chatted casually with Jing Ni.

"Can you feel it now?"

Jingni shook her head: "Not yet."

Having not committed murder or broken her vows for several months and having cultivated her character for a long time, she is now able to control the simultaneous rise of the five vital energies within her five internal organs.

Cao Ze thought for a moment, "Is it because we lack travel experience?"
