When they were about to reach the shore of Erhai Lake, Yulong ordered the army to hide in situ and sent a team of scouts to the Fengbu station to reconnoiter the situation.

After a while, the scouts came to report: there was no anomaly ahead, the lights in the tents were dim, the soldiers were resting, there were not many sentry posts, and the location was obvious, so it was easy to start.

Yulong was overjoyed when he heard this, and ordered a group of infantry to go with the scouts to get rid of the sentries. Then, he turned to the cavalry of the brigade and lowered his voice and said: "Generals, our opportunity to serve the imperial court has come to receive the emperor's favor in this world. You can only move forward, not backward, and those who violate the order will be killed!"

Yulong led a large group of men and horses to the shore of Erhai Lake, and found that as the scouts said, the entire garrison was empty and quiet, and the lights were dim in countless tents, and the soldiers were asleep.

Yulong grabbed the reins of the horse, turned around and shouted in a low voice, "Kill!" Then, with a silver spear in his hand, he kicked the horse's belly violently and rushed to the tent on the shore of Erhai Lake.

The cavalry and infantry behind, following the rain dragon, rushed to the base camp of the wind department like a tide.

When they stormed the camp, they found the tents lit up but empty. The soldiers searched everywhere, but found no human figure.

Yulong roared: "Fooled, retreat!"

It was too late, the chaotic soldiers were like ants on a hot pot, and the fire on the top of the hill behind them was like thunder, and then, like a rain of arrows, the soldiers and horses fell to the ground, and the neighing of the horses and the wails of men were mixed together.

The rain dragon swung his spear, dodged left and right, and flew the arrows to the ground, but the arrows flew more and more.

Suddenly, an arrow shot into the rain dragon's left arm, and he fell off his horse with a groan, and his mount was half-crouched on the ground. The guards next to him hurriedly came to the rescue, but several more people were hit by arrows and fell to the ground.

At this moment, the archers stopped shooting arrows, and countless soldiers rushed down from the mountain, brandishing their blades, shouting all the way, killing the rain dragon's troops, and instantly surrounded them.

Yulong's son, Yu Huan, put Yulong's arm on his shoulder, pulled his father up, and broke out.

Seeing the wind soldiers, rushing left and right, cutting down countless rain soldiers, the rain dragon took a look at his wounds, and he found that he was hit by another arrow in the abdomen, and the blood soaked through his armor, and he was powerless to return to the sky.

"Huan'er, you go, leave me alone, if you can go out, one counts as one. You have to remember that even if there is only one person left in the rain department, you must take revenge, otherwise you will not be worthy of being the descendant of the rain department!" I saw him wielding a silver spear, under the light of the torches, rushing left and right, stabbing down several soldiers who shouted and rushed up in a row, and finally he was outnumbered, was cut to the ground, stabbed a few times, and then trampled under the hooves of a chaotic horse, and the poor generation of famous generals --- the leader of the rain tribe, and ended his life.

Besides, Yu Huan, after being pushed away by his father, wiped a handful of tears, stood up with hatred, picked up a machete, called a few soldiers, and rushed to the weakest part of the encirclement.

That night, the autumn wind whimpered, Cangshan wept, and Erhai was sad. After several killings, the side of Erhai Lake, corpses were all over the field, and rivers of blood flowed, dyeing Erhai Lake red.

Yu Huan had no time to take care of his father's corpse, followed by several followers, rushed out of the encirclement, with a body of blood, hidden in the back mountains by the Erhai Lake, followed the path, starry night, and returned to the rain department of eastern Yunnan.

Most of the children of the rain tribe died on the battlefield, and when they heard the bad news, the men, women and children of the whole clan wailed and wept for the sky.

Yu Huan understands that from now on there is no longer Dali in the world, there is no longer the 37 departments of eastern Yunnan, and the iron hooves of Mongolia will definitely step on every inch of land.

So, in the middle of the night when the geese flew south and the autumn wind roared, the rain department burned down the camp, dismissed the subordinates, destroyed the crops, helped the old and the young, dragged the family with the mouth, left the homeland where they had lived for generations, and embarked on a road of no return.

It is worth mentioning that the Lin clan has always been protected and favored by the rain department, and is willing to follow the master of the rain department until death, but Yu Huan understands that this must be nine deaths and one life, and they cannot be affected, saying that they can establish a contact point in Lasa, and when the rain department is in trouble, they will definitely go to them, which should also be the origin of the Fengyang Inn in Lasa.

No matter how difficult the road is, people will come out, and besides, only by moving forward, there will always be a way to go.

This way, they have been walking for hundreds of years.

"You have to remember that even if there is only one person left in the rain department, you must take revenge, otherwise you are not worthy of being the descendant of the rain department!"

Since then, a seed of hatred has been planted in the hearts of every living Yube people.
