1253, late autumn, Erhai Lake.

In the evening, the sun is setting, and the remaining afterglow shines on the vast water, dyeing the blue lake into blood red. In the back mountain by the Erhai Lake, the autumn wind blew off the only remaining yellow leaves, and there was a solemn atmosphere.

At that time, Kublai Khan, the emperor of the Great Yuan, waved the whip of God, swept the world, and the momentum was like a broken bamboo.

He sat on horseback, raised his horsewhip, pointed to the south, and shouted loudly: "This year, I will sail on the Erhai Lake!"

Duan Xingzhi, the emperor of Dali in the Erhai area of Yunnan, --- still vaguely heard Kublai Khan's chant in his sleep, and he climbed onto the dragon chair tremblingly, looking at the ministers who were helpless in the court, and the old tears were full of tears.

"Could it be that Dali, which has been founded for more than 300 years, has been destroyed in my hands, God, who can stop the iron hooves of the Mongols?"

"My emperor is not anxious, and the minister has a plan to ensure the stability of Dali Society. A young man standing in the corner of the court stood up and knelt in front of Duan Xingzhi, the Heavenly Virtuous King.

The emperor wiped a handful of snot and smiled, "Don't mother-in-law, talk about it quickly!"

"The need for the 37 starry night kings in eastern Yunnan, they have been favored by the emperor and enjoyed glory and wealth for hundreds of years, all because of the emperor's grace and the grace of the lord. Now that the national crisis is at hand, they should stand up and do their best to fight for Dali and relieve our emperor's worries. ”

"Good, good, very good. You big fools are far less thoughtful than a young man. The emperor snorted and scolded as he looked at the ministers with their heads hanging down and trembling.

The young man continued: "Among the thirty-seven divisions, the 'Wind Division' and the 'Rain Division' are the strongest, and they should be used as the vanguard to fight against the Mongol iron cavalry. ”

"Good, good, very good. Do as you say, and immediately draw up a holy decree, and you will take the holy decree to the 'wind' and 'rain' to proclaim it. By the way, I forgot to ask what your name is, it doesn't matter, hehe. After the emperor said this, he was so tired that he closed his eyes and leaned back on the dragon chair.

When the Dali Kingdom was destroyed, the emperor led the civil and military ministers to call the ministers, he was surprised to find that standing in front of them to receive the award was the young man who offered him a good plan, when the emperor understood, everything was too late, maybe this is the example of Infernal Affairs, this is the later words, has long been annihilated in the long river of history, no one knows.

After the sunset disappeared over the West Mountain, Erhai Lake and Houshan gradually fell into a deep darkness, except for the countless tents in between, the lights flickered inside, and the figures were crowded. Outside the tents, countless soldiers were busy packing up the stoves, tidying up their belongings, and leading their horses to drink.

This is the headquarters of the Wind Ministry, where they will meet the Mongol corps from afar according to the Emperor's will.

The Yubu station, which is twenty miles away from Erhai Lake, is a different scene.

A middle-aged man wearing silver armor and holding a silver spear rode on a white horse, he was ---- Yulong, the leader of the rain department, and he received a secret order from the imperial court: the wind department has sent someone to secretly contact the Mongolian cavalry, preparing to cooperate with the Mongolian army inside and outside, and destroy the country Dali.

The rain dragon rode on the horse, facing thousands of soldiers, they were either riding on horses or standing on the ground, all of them were in good spirits, wearing armor, holding blades, the horses spit hot air between their lips, and the horses' hooves kept pulling the ground, just waiting for the leader's order, they could go to Erhai Lake, extinguish the wind department, and eliminate the internal thieves.

Yulong looked at the night sky, his eyes were firm, his gaze was resolute, and his hands were pressed down, signaling everyone to be calm.

Without a doubt, midnight is the best time to attack, which is when Venus (the morning star) gradually rises.

In two hours, we will see the cold glow of Venus.

Yulong waved his arms and shouted, "Let's go!"

The army pulled out, silently, like a long dragon, mighty, target: Erhai Lake.
