In the Sui and Tang dynasties, "the four green dragons were born, and the white tigers were three to the Tang Dynasty" refers to:

One reincarnation: Shan Xiongxin (Qinglong) Luo Cheng (White Tiger);

Second reincarnation: Gai Suwen (Qinglong) Xue Rengui (White Tiger);

Three reincarnations of Qinglong: Su Baotong (Qinglong);

Qinglong Four, White Tiger Three Reincarnation: An Lushan (Qinglong) Guo Ziyi (White Tiger)

Of course, these titles are only fictional in fiction, not real.

A reincarnation: Shan Xiongxin (Qinglong) Luo Cheng (White Tiger); Luo Cheng was entrusted by his parents to lead the generals and brothers of the Beiping Royal Mansion to Shandong to congratulate Qin Qiong's mother on her 60th birthday. Because he didn't like the people in the green forest in his life, and he was conceited of his martial arts, he was looking forward to someone coming to rob the road, and shouted that he had brought a lot of treasures while hurrying on the road, which led to a skirmish with Shan Xiongxin and other people in the green forest who came to celebrate Qin's mother's birthday. all participated in the Jia Liulou uprising. After the defeat of the Wagang army, Luo Cheng, Qin Qiong, and Cheng Yanjin went to Luoyang, and Shan Xiongxin became Wang Shichong's concubine. In order to keep Luo Cheng and the other three, Wang Shichong cleaned up a mansion for him, called the "Three Sages Mansion". Then Xu Maogong disguised himself as a Taoist priest and took away Qin Qiong and Cheng Biting Jin, Luo Cheng stayed in Luoyang due to illness, and then Wang Shichong was named the king of one word side by side. When Li Shimin led his army to attack Luoyang, Luo Cheng escaped from Luoyang City and defected to Li Shimin. After Luo Cheng returned to the Tang Dynasty, Wang Shichong invited reinforcements to help defend Luoyang, and together with himself, he had a total of five anti-kings, namely Wang Shichong, Dou Jiande, Gao Tansheng, Zhu Can, and Meng Haigong. After Qin Qiong was wounded, Li Shimin made Luo the marshal, captured all the anti-kings of the Five Roads, and beheaded Shan Xiongxin.

Second reincarnation: Gai Suwen (Qinglong) Xue Rengui (White Tiger), and Qinglongxing was reincarnated as Gai Suwen, a controversial iron-fisted military dictator at the end of the Goguryeo Kingdom. Attacking Silla and destroying Baekje, Tang sent a special envoy with an edict to Goguryeo to mediate and stop it, but Gai Suwen refused. After the Tang Dynasty Taizong conquered the east, Xue Rengui had a good strategy to settle the war, set the Tianshan Mountain with three arrows, and bravely collected Liaodong. Qinglong was reincarnated as revenge, and at the foot of Phoenix Mountain, Gai Suwen killed twenty-six generals with flying knives, and all the righteous brothers of Wagang. Later, Gai Suwen was chased by Xue Li to the seaside in the Donggang of Wafangdian and killed, because Gai Suwen's blood stained the seaside, so this place was later called Hongyanhe.

The third reincarnation of Qinglong: Su Baotong (Qinglong), Su Baotong's grandfather Su Dingfang, the former subordinate of Liu Heimin, laid a trap on the battlefield to trap and kill Luo Cheng. Luo Tong took the opportunity to kill Su Lin in order to avenge the murder of his father, Su Dingfang under Muyang City wanted to exhaust Luo Tong, did not open the city gate and deceived him to break into battle everywhere, Cheng Biting Jin was furious, opened the city gate, and Luo Tong cut first and then played, killed Su Dingfang, and avenged Luo Cheng's revenge. The youngest son Su Feng fled to settle in the Western Regions, gave birth to Su Baotong and Su Jinlian, and her sister Su Jinlian married into the Hami King's Mansion. Su Bao was united in avenging his family, inciting rebellion, raising troops against the Tang Dynasty, fighting with Xue Rengui and Xue Dingshan's father and son, and locking Yang City on three sides. In the following year, Guo Ziyi recommended Li Guangbi as the envoy of Hedong Jiedu, and united Li Guangbi to divide his troops into Hebei, join forces in Changshan, defeat An Lushan's general Shi Siming, and recover Hebei. An Lushan was defeated and killed. The Anshi Rebellion made the Tang Dynasty flourish and decline.

Qinglong's second reincarnation killed all Jia Liulou's righteous brothers, but failed to kill Qin Qiongwei Chi Gong. Three times reincarnated to kill Qin Qiongwei's Chi Gong son. Qinglong was reincarnated three times to cause trouble to Li Tang in order to avenge the three enmities with Li Tang in his previous life, causing Li Tang IV to decline.

The humble peak is more than 800 meters high, adjacent to Zhuxian Town. There is an official road at the foot of the mountain, which is Dongshan County to the north, and more than 100 miles to the east leads to Baibeast County.

There is a college on the mountain, and its name is Canaan College! The mountain gate is broken, the grass is all over the field, and there is only one old man who is dying of old age, and the wind and candle are in his last years!

Half a month ago, the sky was thousands of miles away, and the galaxy was brilliant. There is a trend of seven stars in a row, and the sky is full of stars swaying the galaxy! Suddenly, a first-class star falls into the mortal dust, faintly invisible! The sky is dark!

On the side of the Humble Peak, there was a strange man lying in the martial arts training ground of Canaan Academy, unconscious! No one knew the origin!

......

Lu Chen looked at the old man dying in front of the bed, and sighed in his heart! As if he had seen the flame of life that was about to be extinguished......

There is a lot of reluctance in my heart, overflowing with words!

"Don't be upset, child...... Ahem...... Person...... Ahem...... There will be death...... Alas......"

Lao Su held Lu Chen's hand tightly, "Heaven will not die, my Canaan Academy...... Ahem...... Send you to me on your deathbed...... I'm dying...... Ahem...... Now I'm going to hand over Canaan College to you...... Ahem......"

"Hope...... Someday...... Can you ...... Ahem...... Let it be glorious again......"

Lao Suo handed a wrench to Lu Chen's hand, and Lao Suo's ruddy eyes were slowly graying...... Lost his lust......

This is the old man's last return to light, Lu Chen looked at the old man who was about to die, and gently closed his eyes, "I will let it regain its glory! Rest in peace......"

Lu Chen didn't know the name of this old man from beginning to end......

For a long time, there is a new low tomb in the mountain behind the humble peak.........

A monument was erected in front of the grave, saying: The Tomb of Canaan

Lu Chen knew in his heart that he was not from this world, and he didn't know anything about this place. Except for the mountain and this dilapidated academy and this old man who just died.

That's all he knows!

I heard the old man say that he picked it up in the martial arts training ground half a month ago...... No one knows why he's here. It's been three years since there was no one on the mountain!

From the old man moved Lu Chen to the bedroom, he was in a coma for three whole days before Lu Chen woke up leisurely!

From the old man's intermittent words these days, Lu Chen gradually understood that this was no longer the earth he was familiar with!

Lu Chen didn't know the name of this world, but only knew from the old man's fragmentary words that this was the Humble Peak of Yunlong Mountain, and there was a small town under the mountain, called Zhuxian Town. It is located in Dongshan County......

The rest of Lu Chen didn't know anything!

Fortunately, the written language in this world is the same as in the previous life, otherwise it may be even more difficult to live!

After getting along with the old man for more than half a month, Lu Chen secretly admired this old man who turned the academy around every day! Although Canaan Academy had been dilapidated for many years......

Now, the old man is gone, and he is the only one left on the mountain! Where to go, Lu Chen is at a loss!

Lu Chen needs to know the world too much!

He had already promised Lao Su to restore the glory of Canaan Academy, so didn't he just leave without hesitation?...... Lu Chen couldn't do it.

Looking at the wrench given to him, it was full of antiquity! The emerald green wrench flickered with inexplicable brilliance......

Lu Chen's ghost put the wrench on his hand!

"Ding, the host has successfully assumed the position of dean and successfully opened the system...... Delivered"

Lu Chen's head was dizzy, and the sky was spinning! When he opened his eyes again, he seemed to be no longer in the world!

What does this mean?

Lu Chen looked up at the starlight in the sky, and there was a gate in front of him, dozens of feet high! The book said: Huaxia Xue Palace! The four big characters are shining! The book on both sides of the gate said: Wen Neng Anbang enjoys eternal peace, and the next book: Wu Ke Ding casts a thousand years of hegemony!

Lu Chen's mind was shrouded in inexplicable meaning between the lines! Lu Chen clenched his fists, his heart surging!

Lu Chen gently pushed the door, and the door opened in response!

Dozens of steps back, pavilions and pavilions, clouds and mist are like a fairyland!

"Who has the big dream first, I know ...... in my life" A sound came to Lu Chen's ears, this sentence seemed to be heard somewhere! Lu Chen came back to his senses and watched the old man like an immortal in front of him walk in front of him.

"I don't know if my uncle is ......!?Where is this?" Lu Chen looked at the fairy wind and looked at it, and he was very respectful in his heart!

I don't know who he is, but he looks very powerful!

"Hehe, don't worry, child. The poor road is called Liu Bowen, you must have heard of it...... Don't be surprised, wait for me to tell you more. Now the place where you are is called Huaxia Academy, as you see the name, but this is no longer the world you are in!"

"So, why am I here? Is that system?...... Dean!?"

"Yes and no...... You can just think of it as a system, in a word, it is to make it easier for you to understand this place! In terms of your understanding: you have become the dean and opened the Huaxia Academy! The Huaxia Academy will be used by you!" Liu Bowen explained with a smile.

"For my use!?" Looking at this fairyland-like place, Lu Chen was taken aback!

"This place has been up and down for 5,000 years, and it is the place where the old Chinese people have been inherited! There is an incredible wonder! This school palace needs to inherit the roots of China with the will of the school palace."

"There's a lot of wonder about this place, and you'll learn about it after that...... The old decay is a deacon for this place, so I will solve so many doubts for you, and the rest is up to you~ I will go" The old man of the fairy wind bone has disappeared!

Lu Chen was in a trance, and returned to reality! As if he had a dream, but he remembered it vividly! Incredible! Huaxia Academy? Liu Bowen, auditory hallucinations, visual hallucinations, Lu Chen shook his head and expressed puzzlement......

"Master, all this is not a dream!" Lu Chen's mind sounded again! Lu Chen looked around, no one!

"Master, don't look at it, I'm in your mind! You can exchange opinions! Liu Lao has already made it clear to you! It's all true!"

"Seven stars are aligned, and the master has come to this world with atmospheric luck, which is valued by the elders!"

......

Lu Chen gradually accepted this fact!"Why am I here?What do I need to do?"

"When you're qualified to know, the answer will be revealed......"

"Ding, the host confirms successfully, and the system is officially started. The Starter Pack has been unlocked, is it enabled?"

"Let's use it......"

"Ding, congratulations to the host for obtaining [Lingxiao Hall (Main Hall)], [Elder: Tong Yuan], [Tiangang Tongzi Gong], [Five Tigers Broken Door Knife], [Transforming Fan Dan], which have been saved in the Admission Palace"

Five light clusters magically appeared in Lu Chen's mind!
