In September of the twenty-sixth year of the curtain opening, Mu Taizu was ill and was unable to govern the government for a while, and the crown prince Mu Liang began to take over the governance of the country.

King Mu Qiyan of righteousness had meritorious service in quelling the southern chaos, but still had no hope of replacing the prince, and Mu Taizu was angry in order to appease his heart, and divided the southern barbarians into the territory of the power of the king of righteousness. Mu Liang knew that the vast northern land had always been a thorn in his father's heart, so he sent someone to Yu to ask Mu Shenyu to discuss the Northern Expedition.

When rumors of the war spread scattered on the grasslands, the Northland tribes, who usually fought petty battles, shared the same hatred and believed that the people on horseback could resist the invasion of foreign enemies. When Zhu Yi met Chulin in the streets and alleys, he heard that the Tart Lun people had rumored about it, and his heart was flustered.

She wondered why the herders of the Northland, who were so friendly and hospitable, were about to suffer from the ravages of war.

Zuo Chu wanted to send her back to Qiancheng before the war broke out, but he didn't leave, and Chu Lin was also in the Northland, so she didn't want to leave.

In October of the same year, the Northern Expedition began.

The general of the Zhenguo Dynasty personally commanded 200,000 soldiers, and gathered with the 100,000 soldiers and horses sent by the Yu State, and marched towards the north. The golden iron horse stepped on, facing the scorching sun of early autumn, and raised thousands of feet of dust in the desert and meadows.

Tu Qincheng hand-picked nearly 200,000 fierce cavalry gathered by various ethnic groups to fight against the curtain of enlightenment. He commanded the battle in the main city and did not rest for many days. The fighting has begun, and the casualties are counted. Zhu Yi couldn't see the smoke of the battlefield, but when he saw Tu Qincheng's frowning eyebrows, he also knew that the battle situation was not optimistic.

In the city of Bayan, the herdsmen and the common people practice day and night, just waiting for the day when the soldiers come to the city, they can do their meager strength.

Although Yu was close to the north and had sufficient supplies of grain and grass, the Han people were mostly infantry, and in contrast, Tu Qincheng's cavalry was fierce and brave, so the Han army failed to break through to the inner belly of the north several times.

At the same time, Song Xiyuan received a secret letter from the pavilion master, ordering her to take advantage of this mess to assassinate and be sure to obtain Tu Qincheng's head. Her body pain worsened, and she couldn't go back to the previous decisive killing situation, so she gritted her teeth and took her life.

On this day, Song Xiyuan went to the informant to get medicine to treat his injuries, and was met by Zhu Yi, who sold medicine. Seeing that she was too weak, Zhu Yi gave her the newly born Gu medicine in her hand. Song Dongchen, who was following Zhu Yi in the dark, finally saw his sister and ran over.

She knocked down all the Gu medicine in Song Xiyuan's hand, and arrogantly refused Zhu Yi's "charity". Song Xiyuan scolded her for being rude, saw her little face that turned from excitement to grievance, and hugged her into his arms in distress. Zhu Yi pouted, picked up the Gu medicine and gave it to the first arrival in the distance.

She talked to Chu Lin for a while, and heard Song Dongchen over there lose his temper.

The two sisters had nothing more than a disagreement over whether to stay or go. Song Xiyuan touched Song Dongchen's soft hair and coaxed for a while.

Zhu Yi didn't bother to care about their sisters, and turned around to buy a few tart clothes for Chu Lin. After that, several people separated.

At that time, Song Dongchen was in a low mood. Zhu Yi didn't pay attention to her, and Gu Zi left. The people who stopped this pavilion followed, and because they wanted to rectify Song Xiyuan, they couldn't do it, so they started Song Dongchen's idea.

Song Dongchen didn't know that there was someone in the dark, she trotted all the way to catch up with Zhu Yi, and shouted "West Girl". shouted like this a lot, Zhu Yi turned around and glanced at her, and sneered, "You and your sister are far apart, no wonder Tingyu doesn't look down on you." The latter roared angrily, and Zhu Yi hurriedly ran away.

At that time, a figure passed by in the room, Zhu Yi paused, and then saw Song Dongchen behind her chasing with a stone in his hand, which scared her to run more happily. On the side of the street, Azanam, who knew Zhu Yi, thought that these two Han girls were frolicking, and laughed to make them run faster.

Zhu Yi walked around a remote alley, trying to get rid of the people behind him. Several figures above him quickly skimmed, and the two people in front of him and behind them all noticed something was wrong, and stopped at the same time. Song Dongchen felt a chill in his back, clenched the stone, and craned his neck to look around.

At this moment, a man in a green shirt jumped up and pounced on her, she exclaimed, and the stone in her hand fell to the ground. Zhu Yi was frightened, and he couldn't remember that he hated Song Dongchen at the moment, so he subconsciously took the bow and arrow on his back to shoot the man.

The other party was agile, easily dodged the arrows, and lifted Song Dongchen, who was stunned. Zhu Yi shouted "let go", and the shadow flew out. When the killer of this pavilion saw the person with the fox tooth mirror, he grabbed Song Dongchen and drew his sword. Several shadows stepped forward to make a move, but this pavilion didn't want to hurt his companions for this, so he immediately left, and Song Dongchen took the opportunity to run to Zhu Yi's side.

Zhu Yi breathed a sigh of relief, and was unguarded by Song Dongchen, who was pale, stretched out his hand and pushed him violently, and said, "Plague, where there is you, where is it not good!" ”

"That's with your sister, right?" Zhu Yi pushed back unceremoniously and ran to the inn.

The people of this pavilion disappeared, and the shadows disappeared again.

The two ran back to the main street, thinking that there was no more danger, and gasped for breath to the inn. Song Dongchen always took a slow step, uneasy because of Fang Cai's danger, and looked back suspiciously, but saw a Han man dressed in a Tart Lun costume smiling at her, revealing the crossbow machine on his wrist.

She was frightened and quickened her steps to catch up with Zhu Yi.

The person in front of him was pounced, and the next moment he was dragged by, and he had to turn around. In the distance, the ice arrow shot out of the crossbow and shot silently, and before she noticed anything abnormal, she saw a green shirt fluttering in front of her, accompanied by a soft snort from the woman.

It's Song Xiyuan.

The man who was hit by the arrow threw Zhu Yi to the ground, and she was stunned when she was crushed underneath. Song Dongchen saw his sister suddenly appear, and blocked the dark arrow for Zhu Yi, and exclaimed to help her.

Song Xiyuan took out a green pill from her arms and stuffed it into her mouth, swallowed the blood in her mouth, she pushed away Song Dongchen, who was helping her, "Why do you pull people to stop the disaster?" ”

Song Dongchen looked aggrieved, "I didn't know anyone ......"

Seeing her like this, Song Xiyuan looked at her silently, with a look of disappointment in his eyes. She understands that after all, she neglected to accompany her, and this sister has already had evil thoughts in her heart.

Chu Lin rubbed Zhu Yi's head and took Song Xiyuan away. Zhu Yi came back to his senses and looked at Song Dongchen, chuckled and walked away.

Back at the inn, Zuo Qi was waiting for the two of them in the hall. He confirmed that Zhu Yi was not injured, and asked Song Xiyuan about his condition. Song Dongchen was reprimanded by him and returned to the room in a sullen voice.

Zuo Qi's face was cold, but Zhu Yi couldn't tell whether he was worried about her or angry that Song Xiyuan was injured. She silently bypassed him and went back to her room.

In the next few days, the active people inevitably encountered accidents again, suppressed their playfulness, and rarely went out.

The Northern Expedition was famous, and Mu Shenyu, as the lord of a country, did not need to go to the front line in person, but he knew that Song Xiyuan was in the north, so he settled everything in the palace and went to the north day and night.

He sent people to form elite troops and fight with the northland cavalry archers for several days, and then ordered the army to march north. Originally, the soldiers who came from afar saw that the northern land could not be attacked for a long time, and their morale was sharply reduced, and there were even those who abandoned their guns and spears and fled. At this moment, King Yu personally commanded the troops to fight, which aroused the hearts of thousands of troops for a while, and there was a great tendency to become more and more brave in battle.

The relatively weak Northland Wasteland Boundary Ridge was lost, and Tu Qincheng ordered the troops to withdraw and retreat, wait for a little recuperation, and fight back together.

The two armies fought, the horn shook the sky, and the flag was blowing. The arrows are flying on the field, the poisonous fire is burning the plains, and the people and horses are screaming, which can be described as changing. The wind and smoke are billowing on the grass, the grass is green and stained with blood, and countless war spirits are always wiped out under the horse's hooves......

When the curtain opened all the way to the Flame City, the pavilion was tirelessly harassing Tu Qincheng. The man in the north, who had a lot of opportunities, had no time to be distracted to deal with it, so he simply slaughtered several killers in the pavilion overnight and clamped down on Song Xiyuan.
