The eldest sister was reborn and the younger sister traveled through time. I just want to survive.

When he was young, Marquis Dingbei was a deputy general who had followed Prince Rong for many years. Not long after Prince Rong handed over the military power, Marquis Dingbei became ill and the relationship between Marquis Dingbei and Prince Rong's mansions gradually became distant.

In fact, the estrangement was only on the surface for outsiders to see. Behind the scenes, the younger generations of the Dingbei Marquis' Mansion received a lot of help and support from Prince Rong.

Gu Yunting went to the northern border at a young age, thinking that he could achieve success with his own abilities. However, he was accused of theft by his superiors before he even went to the battlefield.

When he was beaten to death, an old general pleaded for him and saved his life with great difficulty.

The old general was an old subordinate of Prince Rong. With the old general's advice, he just learned that it was a thousand times more difficult for the men of the Dingbei Marquis' Mansion to gain a foothold in the northern border than for others.

The deaths of his brothers in battle were not God's will, but were intentional by someone with the sole purpose of suppressing the Dingbei Marquis Mansion.

It is not difficult to guess who is behind the attempt to suppress the Dingbei Marquisate. It is none other than the narrow-minded Emperor Yuanjing.

Emperor Yuanjing wanted to control the Northern Frontier for his own selfish reasons, but the generals he chose were all incompetent. At the critical moment, he had to rely on the few remaining veterans to fight the enemy.

Gu Yunting managed to survive in the cracks, and whenever he got the chance he killed the enemy and made meritorious deeds. After going through untold hardships he became famous in the Northern Frontier, forcing Emperor Yuanjing to give him the credit he deserved.

Over the years, if it were not for the care and protection of Prince Rong's former subordinates, Gu Yunting would have almost died at the hands of his own people many times, and would never have had the opportunity to achieve success.

Five days later, at the Dingbei military camp, twenty miles away from Yancheng.

A eunuch who looked like a beggar stood in front of the camp and claimed that he was the fifth prince's personal eunuch.

After receiving the news, General Wu went out of the tent in person to identify the eunuch. After confirming that the eunuch was indeed the Fifth Prince's personal eunuch, he quickly brought him to the tent for questioning.

After listening to the eunuch's story, General Wu was so angry that his eyes were about to burst. He asked in a trembling voice, "Did the Fifth Prince say anything before he died?"

The eunuch cried and sobbed, "His Highness told the general to take good care of Concubine Yu. Concubine Yu is a soft-hearted woman. Without His Highness's protection, she will be bullied."

He knelt on the ground and said, "Although your highness's body was torn into pieces by the vicious dogs, his remains are still intact. I beg the general to retrieve your highness's remains and bury them..."

General Wu was born into a hunter family. His parents died early and he depended on his younger sister when he was young. Even though he now holds a high position and has many wives, concubines and children, he still holds his sister and the imperial nephew at the top of his heart.

Thinking of the tragic death of his nephew and the difficult situation of his sister in the palace, General Wu's last bit of rationality disappeared and he ordered an immediate attack on the city.

The military advisor advised with a panicked look, "General, you must not act rashly. The princess is in the hands of the North Vietnamese Army. If anything happens to the princess, the emperor will definitely blame you!"

General Wu was so angry that he would not listen to any advice. "Even if I am demoted and blamed, I will seek due justice for the Fifth Prince and avenge him!"

When Gu Yunting arrived with his troops, the Dingbei Army had already arrived at the gate of Yancheng.

Before the peace talks failed, the North Vietnamese army did not want to lose any more soldiers, so they used the same trick again and hung the princess on the flagpole on the city wall. Dozens of archers below pulled their bowstrings tight, so that if the Dafeng army attacked the city, they would immediately shoot the princess.

Although this method was despicable, it was effective time and time again. During the first few sieges, whenever the city gates were about to be breached, the generals of Dafeng chose to temporarily retreat for fear of the eldest princess' life.

However, this time General Wu had lost his mind. He did not even look at the princess who was hung on the flagpole. He raised his hand to signal the bugler to issue the order to attack the city.

Just before the horn sounded, Gu Yunting came galloping on horseback, "Don't attack the city."

General Wu glanced at him with contempt, "I advise General Gu to recognize his own status and not to interfere in matters that are not his business. Today, I will definitely break through the gates of Yancheng and retrieve the remains of the Fifth Prince. No one can stop me."

"The eldest princess is of royal blood. If anything happens to her, can General Wu take responsibility?" Gu Yunting asked loudly.

General Wu looked determined, "Whether I can afford it or not, I will shoulder it with all my strength."

This was exactly what Gu Yunting wanted him to say, so he did not try to stop him after hearing it.

General Wu was about to issue another order when suddenly a sharp arrow broke through the clear sky and pierced the slender figure on the flagpole.

The incident happened suddenly and the archers on the city wall looked at each other in confusion, not knowing who shot the arrow. No one had received any order to shoot the hostages.

The eldest princess was shot to death in public. The soldiers of Dafeng were inevitably filled with grief and anger, and they all looked up.

The slender figure that was pierced by the feather arrow moved, and the eldest princess raised her hand and pulled out the feather arrow from her shoulder blade.

At this moment, the eldest princess was dressed in cloth, with disheveled black hair and a haggard look. She was hung on a flagpole several meters high like a rag doll. She did not have any of the dignity of a princess of the royal family, but the look she gave him was exceptionally bright.

"Listen, soldiers of Dafeng. I am the eldest princess of Dafeng. I was born noble and would rather die than live in humiliation. How can we, a great country of Dafeng, be trampled and humiliated by the scoundrels of North Vietnam? Soldiers must conquer Yancheng and take back our Dafeng territory."

As soon as she finished speaking, the eldest princess clenched the feather arrow with both hands and stabbed it towards her lower abdomen with all her strength.

In the last moment of her life, she was still smiling, her eyes were burning.

The bright red blood flowed down the flagpole, each drop was extremely hot, as if it was flowing into the hearts of thousands of soldiers.

General Wu raised his arms high, "Attack the city~"

The horn sounded, and countless sharp arrows streaked the sky. "Charge~" tens of thousands of soldiers rushed towards the city wall like a tide.

The death of the eldest princess was like a shot of adrenaline for tens of thousands of soldiers. The Dingbei Army was unstoppable and broke through the gate of Yancheng in less than an hour.

After nearly three years of fighting, the Vietnamese army was short of supplies, and its men and horses were exhausted. After the city was captured, it was completely unable to resist the attack of the Dafeng army and fled overnight.

At dawn the next day, Yancheng returned to silence.

The eldest princess' body and a mutilated skeleton were placed in an open space next to the city wall.

Yancheng, which had been occupied for two years, was recaptured in one fell swoop, which should have been exciting, but everyone looked sad and did not feel any joy.

"The deceased is gone, General Wu, please accept my condolences!" Gu Yunting said sadly to comfort General Wu beside him.

Seeing it with one's own eyes was more unbearable than hearing it with one's own eyes. General Wu's eyes were bloodshot, and he relied on his remaining willpower to suppress his tears.

The young man who had been clinging to him not long ago, begging him to teach him how to kill the barbarians from North Vietnam, had now turned into a pile of broken bones.

Condolences? How could he possibly condole? Those damned North Vietnamese barbarians, he would definitely annihilate North Vietnam in his lifetime to comfort the soul of his nephew.

Just as Gu Yunting was about to say a few more words of persuasion, the messenger jumped off his horse and knelt down in front of the two men, "Report~The North Vietnamese army has retreated to 50 miles outside the North Gate."

General Wu gritted his teeth and ordered his deputy general beside him, "Deputy General Gao, mobilize 30,000 cavalrymen to chase down the remaining North Vietnamese soldiers."

Gu Yunting urged urgently, "Absolutely not! Our army has fought all night, and the soldiers are exhausted both physically and mentally. It is not wise to continue fighting now. Moreover, don't chase after the desperate enemy. Going north is the territory of North Vietnam, and it is very easy to be ambushed without any preparation."

As soon as he finished speaking, another messenger came running closer.

"A messenger has arrived from Luodu, ordering the general to lead the Dingbei Army to withdraw from Yancheng and return to the Dingzhou camp to receive the order."

Withdraw from Yancheng? All the generals thought that there was something wrong with their ears. They turned their heads to look around. When they saw their colleagues who were equally shocked, they confirmed that what they heard was the truth.
