After millions of years in the library, I became an Immortal Emperor.

The day before the army set off, Li Yu arrived at Xishan.

The large banyan tree in the yard has grown even more lush, its spreading branches covering a small part of the yard and leaving patches of shade.

Li Yu could see the figure under the banyan tree from afar through the open courtyard gate.

He was half-reclining, engrossed in a book. On the small table beside him were an inkstone and a brush, the brush dipped in ink but not dripping.

"teacher!"

Li Yu entered the courtyard and respectfully bowed to the figure on the reclining chair.

Lin Fan put down the book, picked up the tea that had already been brewed, took a small sip, and then looked at him.

"What is it?"

Li Yu took a deep breath and then stood up.

"Sir, I would like to know if the sage who appeared in the Song Dynasty was you?"

He asked, and as he spoke, a hint of nervousness crept into his eyes, even though he knew that the master must be an unparalleled master, perhaps no less than his father.

But that was a saint.

It would allow the human race to continue its existence for tens of thousands of years.

Especially after learning about the alien races' purge and siege of human saints, he understood even more how difficult it was for a human to produce a saint.

He had a guess, but still wanted to be sure.

So he came.

Lin Fan looked at him and smiled slightly.

"I did take a trip to the Song Dynasty a few days ago, met a few people, and acquired some books to fill my library. Now my library can finally be considered to have a proper structure."

Lin Fan said.

Although he didn't give Li Yu a direct answer, Li Yu understood perfectly well that Lin Fan was admitting it.

The sage who appeared in the Song Dynasty was none other than you, sir!

The gentleman is a saint!

He could hardly contain his excitement, and his body even trembled slightly. He knew all too well the significance of a sage to the Tang Dynasty and humanity.

It was like tearing a ray of light through the darkness, giving them hope.

The Tang Dynasty was plagued by invasions from barbarian tribes and stone tribes. Other parts of the human race's Nine Provinces were not necessarily better off than the Tang Dynasty. In comparison, the Tang Dynasty was actually better off.

Humanity is facing the threat of extinction. While a sage may not be enough to truly elevate humanity, he can help them escape this predicament.

Lin Fan looked at him and shook his head slightly.

"The world is vast, and what you can see is not the whole picture. There are worlds beyond worlds, so we should always have awe for this world."

Lin Fan said.

He controls countless Great Daos and has also evolved the Chaos Great Dao. He has come to understand some things beyond the heavens and earth. Although he cannot see them clearly, he already knows that the Xuanhuang Great World is not the only Great World.

Furthermore, based on his previous life's experiences, he knew that fantasy novels often featured nested stories, but upon reaching the pinnacle and stepping out of this world, he never imagined that he was just a frog in a well.

The so-called supreme powerhouse is merely a being at the very bottom in another world.

Upon hearing this, Li Yu's expression changed, and he immediately became serious.

"Sir, Li Yu understands."

Although sages are powerful, the Xuanhuang Great World still has myriad races. Among the top races such as the demon race, the spirit race, and the winged race, there are not only sages, but also great sages and quasi-emperors.

The master was telling him not to limit his vision to the Tang Dynasty and the human race, but to look at the entire Xuanhuang Great World.

As a ruler, he should have the ambition to lead the human race to rise again.

We shouldn't only see what's in front of us.

Lin Fan looked at him and nodded.

He is indeed a teachable child.

Cultivation emphasizes stability. The path of stagnation is like an eternal night, and those who leap the fastest are always the ones who die the fastest. The Great Sage Realm is far from enough.

"What is your opinion on the Tang Dynasty's northern expedition? The southern border is under attack by barbarian tribes and is already in a difficult battle. Isn't it too hasty to launch another northern expedition at this time?"

Li Yu asked again.

Lin Fan was taken aback upon hearing this, then shook his head and smiled.

"I am just a scholar, I don't understand the affairs of the world. You are the emperor of the Tang Dynasty, so whatever you think is right is right. Since you have already decided to launch the Northern Expedition, you shouldn't be asking me this question."

"There has never been a war without a cause since ancient times. Once a war has begun, its legitimacy should not be questioned."

"A ruler should have the power to unite the feudal lords nine times and bring order to the world."

Lin Fan said.

This young king has great ambitions, but he is too cautious, both in the court and in war. It's not that this is a bad thing.

Previous emperors, including the former emperor of the Tang Dynasty, did the same thing; he was simply continuing their work. It was already quite an achievement to have done so well.

After all, the human race is weak, and it is not advisable to fight a losing battle with an egg.

Upon hearing this, Li Yu was shocked, as if he understood something, and bowed to Lin Fan.

Li Yu understood.

He then took a deep breath and asked the question he most wanted to know in this line of work.

"The Stone Clan has a Lord of the Mountains, an ancient saint with incredible power. Li Yu wants to know, if the Lord of the Mountains were to descend one day, could you withstand him?"

The Northern Expedition can only achieve minor victories. A major victory would damage the foundation of the Stone Clan, who would surely awaken the Lord of the Mountains, at which point no human force could withstand it.

He was unwilling to accept that such a costly battle, which exhausted the nation's resources and depleted the strength of the northern border, could only result in a minor victory.

This is also why the human race has never dared to launch a large-scale invasion of the territories of other races. The last time the King of Zhennan invaded the barbarian tribes and caused their extermination, it was rumored that a barbarian saint had intervened.

"The Lord of the Mountains?"

Lin Fan was slightly taken aback.

He looked towards the north of the Tang Dynasty, a chaotic aura swirling in his pupils. The world opened up before him, and invisible chains of rules trembled, pressing down on Lin Fan layer by layer.

Li Yu felt a tremor run through his body and even his soul, as if some great terror had descended and was about to wipe him from the world at any moment.

"gentlemen……"

He said tremblingly, not knowing what had happened.

The only person he could turn to for help was his husband.

Lin Fan's gaze pierced through space, landing on the land that the human race had not yet set foot on, and he saw the towering mountains and countless stone creatures.

As if sensing his gaze, a pair of enormous pupils opened their eyes amidst the mountains, and the mere act of opening their eyes caused an earthquake.

"Who?"

The deep voice sounded like the murmur of the entire earth.

The sense of being watched vanished in an instant, as if it had never existed, but the Lord of the Mountains saw strands of lingering power of rules.

A tremor surged in his enormous pupils.

Just a glimpse of something being observed has triggered the power of the rules. Who is the owner of this gaze?

Could it be the demon race or the spirit race? As for the human race, he had never thought of it. If it were 100,000 years ago, he would still be wary of the human race, but now he no longer takes the human race seriously.

In the courtyard, Lin Fan withdrew his gaze and looked at Li Yu. The chaotic aura dissipated, and the chains of rules disappeared. Only then did Li Yu feel that he could breathe again.

"The Lord of the Mountains is indeed extraordinary, but he cannot hinder the Northern Expedition."

Before Li Yu could ask, Lin Fan said something.

Li Yu's expression changed drastically.

"Go."

"Do whatever you want. A king should have the majesty of a king. What the Tang Dynasty needs is not a ruler who can maintain the status quo, but a king who can usher in an era of lasting prosperity for mankind."

Lin Fan said.

Li Yu nodded, bowed deeply to Lin Fan, and left.
