After Gu Tingye opened the envelope, there was a piece of letter paper and a folded portrait inside.

Gu Tingye first opened the portrait and found that it was a picture of himself. However, it was not his usual self, but a picture of him riding a horse and fighting.

Minglan painted him bravely fighting the enemy very vividly, and from the painting we can tell that his little girl also missed him.

After looking at the portrait for a long time, Gu Tingye reluctantly put it down and picked up the letter. The letter was filled with expressions of concern for Gu Tingye, and at the end was a single sentence: I'll wait for you to come back.

After reading the letter, Gu Tingye picked up the portrait again.

The smile on his face could no longer be suppressed. After laughing three times with his head tilted back, his heart felt warm as if it was summer.

Holding the portrait in his left hand, he wrote the letter to be sent to the capital city today with his right hand.

After a huge fire broke out overnight in the Northern Frontier royal family's lineage, King Beijiang, Lan Lanhe cried until dawn before turning around and standing up.

He held the head of his second brother, Haji, and placed the body of his third brother, Hashi, on his horse. He stood in the king's tent for a long time, tears streaming down his face, leading the horse, and finally left without a trace.

Gu Tingye stayed in the northern border for another two months before being recalled to the capital by an imperial decree. After arriving in the capital, Gu Tingye finally understood what had happened.

The Queen and Princess Jinyi studied the notes left by Queen Jing'an for two years, and a few months ago they figured out one of the strategies that would benefit the people.

Empress Jing'an left behind a method for preventing smallpox, but the instructions were unclear. The notes stated that the cowpox method involved extracting smallpox fluid from cows and then inoculating it into uninfected people.

After several months of civil unrest in Northern Frontier, the newly appointed King of Northern Frontier submitted a peace petition to the Central Plains. This petition stated that upon ascending to the throne, he would cede two cities, lead his tribe to a distance of one hundred miles, and refrain from further aggression against the Central Plains. He also pledged to send his own daughter to the Central Plains royal family as a concubine, demonstrating his sincerity.

Gu Tingye's main mission when he returned to Beijing this time was to escort the former King of Northern Frontier and the former Queen of Northern Frontier back to Beijing, and secondly to bring Naier, the daughter of the new King of Northern Frontier, to Beijing.

General Gan would be stationed at the northern border until the emperor chose a new person to replace him ten years later. General Gan, who loved to adopt daughters, gave his newly adopted daughter, Liu Chuchu, to Gu Tingye when he left the northern border.

Gu Tingye didn't even glance at Liu Chuchu. He sneered and then bowed to General Gan and said, "I see that Miss Liu admires you very much. Why don't you show her more pity?"

After saying this, he strode away. When Gu Tingye returned to Beijing this time, he was a fourth-class general, only two levels lower than General Gan.

Not to mention that Gu Tingye has never had any concubines in the Ningyuan Marquis Mansion since he was born, but in order not to make Minglan sad, Gu Tingye had to lose face and accept this woman.

Gu Tingye didn't stop even when he heard General Gan's shout from behind.

But when they were about to return to the capital, Liu Chuchu was still stuffed into the team returning to the capital by General Gan. Smiling kindly, he said to Gu Tingye, "Please help me, Gu Erlang, to send my adopted daughter back to the capital."

Gu Tingye was so angry that he laughed. Even if nothing happened on the way back to Beijing, he would not be able to explain it when he arrived in the capital.

He waved to his subordinate Zhang Hu and said to him, "You haven't married yet, have you? This is General Gan's adopted daughter. Please take good care of her on your way back to the capital. Once we get there, I'll arrange your wedding."

Zhang Hu, a man of obedience, immediately agreed, "Thank you very much, General, for your kindness."

After saying that, he reached out and pulled Liu Chuchu towards the team, completely ignoring General Gan's cold face and Liu Chuchu's cries.
