The mountains in summer are like a beautiful young woman, combing her flowing long hair. Her enchanting figure is wrapped in a layer of green silk, but her graceful lines are still clearly visible. She is noble, elegant, and full of vitality, calling to all life with the most primal sincerity.

After traveling for six days, they arrived at the foot of the Qinling Mountains, where four thousand soldiers from the Left Garrison and Left Valiant Guard had already set up camp.

The beautiful scenery was always refreshing, and the area around the camp had already been cleaned up, so Qin Mu let his younger sister and the others play freely. He didn't worry about the training; he only needed to make plans and let Cheng Huaimo and Yuchi Baolin carry them out. The two of them really enjoyed training. Qin Mu knew it was because they liked to show off, especially when they were training the soldiers to the point of exhaustion.

The soldiers from the Six Doors were assigned to be captains, with Li Chongyi assisting, leaving Qin Mu with some free time. Of course, he wasn't truly without anything to do; having promised to teach the princess, he couldn't break his word.

"Heaven and earth possess righteous energy, which manifests in myriad forms. Below, it becomes rivers and mountains; above, it becomes the sun and stars..." The clear, melodious sound of reading aloud rang out in the camp. Ten girls sat opposite Qin Mu under a large tree, reading aloud along with him. Nearby, the Xuanjia soldiers stood with their backs to them, dutifully guarding the area. Hearing the reading, their backs straightened even more.

Last time at Rugui Tower, Qin Mu discovered that the others had forgotten the Song of Righteousness afterward, so he wanted to find out why. This time, he simply used the normal teaching method to teach the Song of Righteousness, explaining not only its meaning but also its content.

Qin Mu himself had studied the concept of righteous energy extensively, and combined with his knowledge, he explained it in a simple and easy-to-understand way. The understandings of righteous energy from Mencius, Confucius, Guiguzi, and even Daoist schools were all within the scope of his explanations. Qin Mu's explanations often incorporated anecdotes, making them all very interesting to listen to.

Because this world had fewer nomadic tribes, Qin Mu adapted some events from his own world into it, such as the Five Barbarian Invasions, the massacres of Han people by the Jin, Xia, and Yuan dynasties.

In this world, the Righteous Qi is one of the spiritual energies used for cultivation. However, in Qin Mu's previous world, the Righteous Qi was understood as mindset, temperament, and thought. Therefore, Qin Mu wanted to reverse this, using mindset and thought to promote the cultivation of the Righteous Qi.

Mindset can be changed, and thoughts can be cultivated. So, once thoughts are firm, isn't it easier to cultivate oneself? Isn't setting goals one of the conditions for entering Confucianism?

Once he had this idea, he couldn't wait to start verifying it. Constantly educating and brainwashing, and constantly learning about various righteous people and things, is a way to change one's mindset.

Good poems and articles have the power to move people, and of course, songs are also a way to inspire people.

So Qin Mu taught his soldiers to read and tell stories during the day, and organized them to sing songs at night. "Serve the country with utmost loyalty!" "Soldiers!" "Men should strive for self-improvement!" These three songs became daily rituals.

What everyone loved most was listening to Qin Mu tell stories, from Qu Yuan and Su Wu at the very beginning, to the Romance of the Three Kingdoms! Qin Mu told these stories. However, under Qin Mu's conscious influence, he focused on analyzing the unparalleled loyalty of Guan Yu, the devoted Zhao Yun who rescued the young lord, the selfless Zhou Yu who poured his heart and soul into his lord, the devoted Zhuge Liang who served Shu to the death, and Jiang Wei who dedicated his life to Shu. He included their actions throughout their lives, as well as his own speculative interpretations.

When searching for a treatment for hyperthymesia, he learned of a brainwashing method: self-hypnosis, which involves constantly emphasizing and using mental suggestions to strengthen one's resolve. Of course, this could also be considered an extreme approach.

During the day, the soldiers trained, hunted, and gathered herbs. At night, they sang and listened to stories. Qin Mu gradually discovered that a large number of them had become fanatical. However, their fanaticism stemmed from their love for the country and a strong sense of justice.

It wasn't just the soldiers; the ten girls, who were more educated, changed even more. Even the youngest, Qin Yuling, was constantly chanting "acting on behalf of Heaven." No one knew where she'd heard that phrase. Qin Mu was certain he'd never told a story from *Water Margin*.

It wasn't until one day, when Qin Mu overheard Xiangli Yanran telling stories of the martial arts world, that he guessed the reason.

Through continuous explanation and instruction, Qin Mu discovered that his righteous energy was becoming increasingly condensed, emitting a whiter light; what was originally milky white had now become dazzling. Meanwhile, the golden component in his blood was also increasing, inexplicably reminding Qin Mu of the phrase "loyal heart and unwavering loyalty."

"碧血丹心" itself refers to the heart and blood of a loyal and upright person. Literally, "碧血" means color; however, Qin Mu knew that "碧" also had another meaning: change or transformation.

Not only Qin Mu, but also Qin Yuxin, Cheng Ying, Cheng Lin, Princess Pu'an, and Princess Anyang have undergone some changes. The girls who were originally somewhat weak have become more spirited. Their cheerful personalities have become more outgoing, and their eyes have become more determined.

Of course, it's not that the others haven't changed, it's just that they've changed the most.

“Huai Dao, something’s not right.” Half a month later, Cheng Huaimo returned to the camp and found Qin Mu.

"What happened?"

"None of the four squadrons encountered any prey today!"

"None of the four battalions?" Qin Mu asked in surprise.

“That’s right, I just found out too. Something feels off, so I’m discussing it with you,” Cheng Huaimo nodded.

This time, he actually brought two princesses with him, claiming it was to escape the summer heat, but they ended up in this remote corner. Everyone knows there's a reason behind it. However, half a month has passed without anything happening, so they've let their guard down. Today, Cheng Huaimo suddenly felt something was off.

Qin Mu was naturally very concerned about this matter, after all, he was the official person in charge of this operation. The hunting expedition would choose a new mountain area every two or three days, so it was impossible for there to be no prey. You must understand, the mountains in this world are much larger than those in the other world; continuous mountain ranges, towering into the clouds, with altitudes of two or three thousand meters being commonplace. How could such vast mountain ranges not have any ferocious beasts?

Not only are there ferocious beasts, but there are many of them. The saying "two tigers cannot share one mountain" simply doesn't apply to this world. It's normal for couples to work together, and there are even couples with two kids, or there might be one family on the mountainside and one on the mountaintop.

Bears, leopards, and wolves are the most basic ferocious beasts, especially the forest wolf, which is no less formidable than a leopard. However, these are not the greatest threat to the Qinling Mountains. In order to deal with the Central Plains, the beastmen have been constantly probing attacks or sending assassins to sabotage the area over the years. Some of these beastmen have fled into the mountains, where they use their unique characteristics to organize wild animals and attack villages.

This situation is not new; it has existed for over a thousand years, which is why there are families and sects stationed in various regions.
