In my dream of returning to the Tang Dynasty, I snatched Wu Zetian from my lap.

Over seventy years old, which would be considered advanced age in later generations.

Looking at his head full of white hair, Li Yuanchang suddenly realized that even heroes have their end. In history, Li Jing died a few days earlier than Li Shimin.

Online sources jokingly say that Li Shimin waited until Li Jing died before daring to die himself.

This is enough to show that Li Jing was indeed invincible, even surpassing Li Ji, who was also one of the Ten Philosophers of the Martial Temple.

Not long after.

Li Jing led Li Yuanchang to a dusty woodshed.

There was nothing inside except a coffin.

Li Jing chuckled and said, "Your Highness, you're getting old; you should prepare your wooden armor in advance."

"Wooden clothes" refers to coffins, which were called "clothes for the dead" in some regions in ancient times.

Li Yuanchang didn't know what to say, so he quietly looked at Li Jing.

He struggled to push open the coffin lid, but seemed to lack the strength. Li Yuanchang stepped forward and helped him easily push the coffin open.

"Getting old, getting old," Li Jing said with a self-deprecating laugh, bending down and rummaging inside the coffin.

By the light, Li Yuanchang saw that there was a hidden compartment inside the coffin, and Li Jing took out a book from it.

Judging by its condition, it's not old.

"Your Highness, this book is the culmination of my life's work, and it is called the Mirror of the Six Armies."

Upon hearing this, Li Yuanchang was greatly shocked, and his pupils dilated instantly.

Six-army mirror!

The legendary and famous military treatise of Duke Wei, which has been lost to the annals of history!

This thing is comparable to Sun Tzu's Art of War in terms of military value. Moreover, this is the original. What has been passed down to the 21st century is just a compilation by Qing Dynasty scholars from a large number of ancient books.

Its gold content and authenticity remain to be verified.

What was now laid out before Li Yuanchang was the genuine work personally presented by Li Jing. At that moment, his breathing became rapid!

To put it bluntly, this is a "Heavenly Rank Technique"!

Li Jing patted the dust off his clothes and said, "Many years ago, His Majesty ordered the Duke of Chen, Hou Junji, to come and study military strategy."

"I am not pleased with this."

"At that time, Hou Junji was indeed the undisputed famous general of the younger generation of the Tang Dynasty, and the one most capable of inheriting my mantle."

"But in my observation, this man has character flaws. He is not broad-minded enough and is too arrogant. If we hand over the military treatise to him, no one will be able to control him, and it may lead to a catastrophe."

"Therefore, in order to complete the task assigned by His Majesty, I only taught half of it, and the military strategies I imparted were passed down orally, without teaching too much of the real stuff."

"Hou Junji also harbors some resentment towards me for this."

"Your Highness knows what happened next; Hou Junji indeed brought about his own destruction."

As he spoke, his expression didn't show disdain, but rather a sense of regret.

It is clear that Hou Junji's impending doom was something that the "God of War" regretted.

Li Yuanchang listened quietly to his story.

Li Jing, his back hunched, said, "I thought I would never find a suitable successor in this lifetime, someone who possesses both Hou Junji's military talent and the benevolent heart to unite the world."

"But now..."

As he spoke, he drew out his words and turned back to look at Li Yuanchang with a smile.

"It's yours now."

Li Yuanchang was shocked.

"this……"

"Duke Wei..."

Li Jing waved his hand, stopping him from continuing, and then stuffed the military treatise into his hands.

"I considered taking these things with me to the grave, but after much thought, I realized it would be such a pity if no one were to inherit them."

"The Tang Dynasty has been established for less than a hundred years. These things will still be needed in the future. Give them to Your Highness, and Your Highness can protect the Tang Dynasty for at least fifty years."

"This can be considered the last thing I leave to the Tang Dynasty before I die of old age."

"You need not worry about anything. This 'Six Armies Mirror' was secretly written by me; no one knows about it, not even Your Majesty."

Li Yuanchang swallowed hard, realizing that Li Shimin also had Li Jing's military treatise.

However, its full name is "Li Weigong's Questions and Answers," and its military treatise exists in the form of a dialogue. It records the conversations between Li Shimin and Li Jing about military discussions, essentially a privately commissioned version for the emperor.

This book, which was lost in history, is a military treatise written by Li Jing himself, and it is estimated that the contents of it are more authentic and more complete than those of Li Shimin!

"Lord Wei, we are not acquainted, why do you give such a family heirloom to me instead of to your descendants or former subordinates?"

Li Jing stroked his beard and smiled.

"They are all less talented than you. I know about all the battles you fought, the guards you trained, and the newfangled composite bows and other novelties that have emerged."

"His Majesty knows as well."

"Let me tell you another secret."

"Do you know that after Hou Junji's death, His Majesty secretly summoned me once?"

Li Yuanchang shook his head.

Li Jing said, "His Majesty intended to cultivate you back then, and even tested me to see if I was willing to pass on my military strategies to you."

"I refused at the time."

"Huh?" Li Yuanchang was taken aback, but not because he was surprised that Li Shimin wanted to groom him. It was indeed their honeymoon period at the time, and Li Shimin was in good health and needed him to handle things.

"Then why are you doing this now?"

Li Jing smiled and said, "At that time, I could tell that Your Highness was no ordinary person. I also heard about Your Highness's benevolent deeds in Liangzhou. Naturally, I was willing to help."

"But if I had said yes back then, wouldn't that have harmed Your Highness?" he said meaningfully.

Li Yuanchang understood instantly!

This man had been under strict surveillance by Li Shimin for over a decade, always trying to protect himself; how could he not know his current predicament?

"Lord Wei's insight is brilliant; I admire it."

Li Jing waved his hand and sighed, "A ruler is a ruler, and a subject is a subject; the closest of kin can be the most distant."

"Keep this book safe. It might be helpful for your trip, and it will also help me pass on my legacy. I have high hopes for you."

Li Yuanchang was moved.

Many senior officials in the court were friendly to him, but Li Jing was the most special because they were not familiar with each other and there was no conflict of interest between them.

The fact that people like Cheng Yaojin took care of him was largely due to their connections with Cheng Chuliang and others, and they also hoped that Li Yuanchang could help their children in the future.

Only Li Jing helped him without any personal gain, and even directly taught him the "Six Armies Mirror," a skill that countless people coveted!

This is the military treatise of a military genius!

By the Song Dynasty, it was one of the Seven Military Classics officially designated by the emperor.

He bowed deeply and said in a solemn voice, "Student thanks you, teacher!"

Li Jing laughed and said, "I am merely giving you a book on military strategy; I am not your teacher."

Li Yuanchang shook his head: "In any case, respecting teachers and valuing the way, even if Duke Wei gave it as a gift, it still shows his intention to teach."

An unprecedented look of kindness appeared on Li Jing's aged face.

"It's a pity that we've met. I'm too old, and His Majesty is too old. Otherwise, I would be happy to take you as my student."

With the simple phrase "Your Majesty is getting old," Li Jing actually understood everything.

"I have nothing to repay Your Highness for your bow, so I will give you one more piece of advice, shall I?" he suddenly said.
