In Qin Feng's reflection, Shu Chang is a typical bold person, a guy who can't blink his eyes when he collapses in front of him. When I first met him, I saw Shu Chang's bold experiments, even a person with a heart-wrenching nature like Qin Feng was frightened, but Shu Chang was unmoved.

But now, Qin Feng rarely saw a look of fear in Shu Chang's eyes. This made him straighten his back and solemnly face the big secret in Shu Chang's mouth.

"What is it? Even you are scared?" he asked slowly.

Shu Chang took a breath, as if he had made himself calm down, and then said: "This is a note, which was left by the first secret sect leader. It records some things when Emperor Li Qing unified the world. Qin Feng, do you know the Battle of Chang'an?"

"Of course I know!" Qin Feng said: "This is recorded in historical books, and there are many legends about this battle among the people. It was during this battle that Emperor Qing defeated the 500,000 elite soldiers of the Great Zhou Dynasty in one fell swoop, which laid the foundation for the founding of the Tang Dynasty. This is a legendary battle."

"Do you know how many troops did the Emperor lead at that time?"

"Fifty thousand!" Qin Fengdao.

"It's over 50,000, and it's in a plain area like Chang'an. If you were leading the troops, do you think you could do it?" Shu Chang asked.

Qin Feng was stunned, "It depends on how the opponent is. At that time, Moluo had hundreds of thousands of people, but he lost to me in the end. At that time, even if I had the troops in Shayang County, there were only more than 10,000 people."

"What if those people were fully armed and well-trained troops? I mean, at least not weaker than the current soldiers of Qi." Shu Chang's voice became lower and lower.

"This is impossible!" Qin Feng seemed to realize something, widened his eyes, his face full of shock, "If there were so many elite troops in the Great Zhou Dynasty at that time, even if the Emperor had brought an army composed of all martial arts masters, he would not have defeated them head-on."

"This is true." Shu Chang said: "This battle laid the foundation for the founding of the Tang Dynasty and swept the Zhou Dynasty into history in one fell swoop. However, in the history books of the Tang Dynasty, the description of this battle was very brief. Hehe, the emperor led 50,000 troops to fight with the enemy's 500,000 troops on the bank of Chang'an and broke it. Just a few words, shouldn't such a war that has been famous in history be written in a very special way? Why is it recorded in the history books so briefly?"

"Why?" Qin Feng was also stunned, "Yes, why? Do you know why now?"

"I understand!" Shu Chang sighed, "But I can't believe it."

Qin Feng looked at Shu Chang and fell silent. He was waiting for Shu Chang's following.

Shu Chang took out a yellowed and extremely ragged booklet from her arms, "This is something left by the first secret sect leader. The first secret sect leader finally disappeared with Emperor Li Qing."

Staring at the booklet, Qin Feng did not flip it, he still looked at Shu Chang.

"More than a thousand years ago, there was no city of Chang'an. At that time, the capital of the Great Zhou Dynasty was Luoyang. But this war occurred in Chang'an, and it was only after this war that Chang'an City was founded. Here, after the Emperor defeated the 500,000 army of the Great Zhou Dynasty, he began to build a city here. This is the capital of the Tang Dynasty and now the Great Qi Dynasty. "Shu Chang's voice was very low. "Five hundred thousand army, Qin Feng, you are fighting an old battle. If it were you, killing the 500,000 army to defeat the army and losing more than 90%. How long will it take?"

“It’s hard to say.”

"Emperor Li Qing spent all night."

Qin Feng's face turned pale, "One night? Even if these 500,000 people stood there and were waiting for them to kill, they would not be able to complete it overnight."

Shu Chang rubbed his face hard, as if he wanted to make himself more awake. "The night's battle was recorded on the notes of the Lord of the Secret Sect. The 50,000 people of Emperor Li Qing did not participate in the war. Their biggest role was to clean up the mess after the war. At that time, Emperor Li Qing and his dozens of masters including the Lord of the Secret Sect arrived at the suburbs of Chang'an late at night. The current location of Yulong Mountain, and at that time, there was no Yulong Mountain. Haha, in addition to An'an's effect, a mountain suddenly appeared in that place, which really looked quite unnatural. But after watching it for a thousand years, I got used to it, right? Everyone thinks that this mountain should exist where."

"You are talking about Yulong Mountain, the royal forbidden land of Daqi now!" Qin Feng asked.

"It is not only the royal forbidden area of ​​Daqi, but also the royal forbidden area of ​​Datang in the past." Shu Chang said. "The secret I mentioned is where. According to the records of the Master of the Secret Sect, that night, the Emperor brought them to the place. Then, a giant beast floated from the ground and took root in the open night. Countless bright lights cut through the night sky. It was not the light that brought light, but the sword of the god of death. Wherever the light passed, the military camp of the Great Zhou Dynasty was cut open in pieces. Huge weapons flew out from the monster's belly and landed accurately in the army of the Great Zhou Dynasty. The sound was as loud as thunder, and the fire reflected the sky. He could even see countless people's bodies dancing in the air like fallen leaves, and then turned into nothingness."

Qin Feng clenched his fists: "What kind of power is this?"

"I don't know, he doesn't know, and Emperor Li Qing never mentioned it, he has never said it in the past, nor has he said it after this battle." Shu Chang sighed, "I have carefully studied the history of the era of Emperor Li Qing and the battle lines of the Emperor. He seemed to have been preparing to fight the Zhou Dynasty here from the beginning. Even at the earliest, he had been failing, but he never gave up his efforts. It seems that from the beginning when he started the army, he had thought about the decisive battle here. It turns out that I have never understood why the Emperor wanted to do this? Even if he led 50,000 troops alone and tried his best to break through here, regardless of the way he was cut off and surrounded by all sides. At that time, every soldier under the Emperor thought they were going to fail. But overnight, history turned over. It turned out that the Emperor had known that there was something he needed here, something that could change history in an instant, and he knew how to manipulate him."

Shu Chang lowered his head and murmured: "Qin Feng, this is not the power that the human world should have. This is also the reason why there is only a simple sentence about this battle in the history books of the Tang Dynasty. Because in that battle, the Great Zhou Dynasty was not competing with people at all, they competed with ghosts and gods!"

Qin Feng exhaled a breath of turbid air, "What's next?"

"Later? The elites of the Great Zhou Dynasty were lost overnight. Those who escaped by chance were both devastated. They all believed that Emperor Li Qing was recognized by God and received help from ghosts and gods. The rule of the Great Zhou Dynasty collapsed in the following years. Countless families defected to Li Qing, civil officials and military generals of the Great Zhou Dynasty, and surrendered in the wind."

"That's definitely not helping the ghosts and gods." Qin Feng said affirmatively. "The big secret you are talking about is it?"

"Yes, it is it, that location is Yulong Mountain." Shu Chang said: "After that, the emperor ordered the construction of the mountain here. Yulong Mountain was not naturally generated. It was built with human power by Emperor Li Qing. Then, it became a royal forbidden area." Shu Chang said.

"Then there is a secret of Emperor Li Qing's victory!" Qin Feng said slowly: "It must be the highest secret of the Tang Dynasty, but I don't understand why the last king did not take him out when the Tang Dynasty fell. Since he had such great power, how could he not defeat the Qi family at that time? Although the Qi family is strong, it can't stand the military strength of the Zhou Dynasty at that time, right?"

"I don't know." Shu Chang shook his head: "I only know that the last king of the Tang Dynasty did die on Yulong Mountain. And now, that secret belongs to Qi State and Cao Tiancheng."

Qin Feng stood up, his face was solemn, and he walked around the room. After a while, he stopped and turned to look at Shu Chang, "The Tang Dynasty did not show such a power back then. Does it mean that he could no longer show up? Or, this power is his ability that time."

"Maybe!" Shu Chang said: "But Qin Feng, no one is willing to give up such power. Qi State must have been looking for this reason. What is Cao Chong studying? Are he really studying what is it after studying the master? He also took away Wenhui Zhang and Weizhuang. It has been many years since they have not come out. Are they exploring this secret? "

Qin Feng knew what Shu Chang was worried about. If the Ming Dynasty wanted to unify the world, one day it would definitely lead to the city of Chang'an. If such power was already controlled by the Emperor of Qi, then no matter how many troops he brought there, he would just send sheep into the tiger's mouth.

"Don't forget, whether it is Wenhui Zhang or Wei Zhuang, they are not hostile to me." Qin Feng said: "If there is really any power beyond this world, I think I will know it."

Shu Chang smiled bitterly: "Cao Chong is using the power of Wenhui Zhang and Wei Zhuang. The three of them are the most powerful and knowledgeable people in the world. If you really know something, do you think they can still come out?"

"I will figure out this problem." Qin Feng sat down slowly, his mind a little aches. He couldn't help but think of the things that Wenhuizhang and Weizhuang once gave him, those things that were said to be left by Emperor Li Qing. Why can he understand the meaning at a glance? Those things obviously have never appeared in this world, and he has never touched those things, but at that glance, he seems to know what it is.

His face was very bad, "I will figure it out. Maybe at some point, I will go to Yulong Mountain to take a look."
