In danger, he traveled through time to save her, and the black-bellied prince doted on her

Li Huaijin pinched her nose: "Secret."

A voice came from outside the tent: "Princess, Lord Su wants to see you."

Mu Jinan stroked his messy black hair, like a cat that had been caught stealing food: "What should I do? Where are you hiding?"

Li Huaijin sighed, put on a mask, and leaned on a cane. Why did he hide? Did he really regard him as a lover? Mu Jinan blocked him and wiped off the rouge on his lips. She sat in front of the documents.

Su Heyan was wearing a green bamboo robe, eight feet long, solemn and stern, with cold eyes and eyebrows. Although he was young, his gestures showed that he was a mature man in his thirties or forties:

"Meet the princess."

Mu Jinan: "Master Su, what brings you here?"

Su Heyan turned and looked at Li Huaijin, a smile on his lips: "Greetings, His Royal Highness Prince Liang."

Mu Jinan took a peek and found out that they knew each other. She stayed aside and listened to their discussion. Su Heyan took out the blueprint:

"This is called a chariot, pulled by oxen, wide in the front and narrow in the back, with long hubs and large wheels and short axles. The wheels are four inches thick and the axles are five inches wide. The body of the chariot is covered with a wooden shed and felt. This chariot is good for traveling in the mountains."

"It was originally intended for Qixuan, but his clan owed money on credit, so now it's not enough."

When Li Huaijin was besieged by Xiao Yan's archers in the woods, he thought the forest was magnificent, so he sent the Killing Flame Army to explore it. The depth of the forest was immeasurable, and with the advantage of nature, it was easy to get the materials for building a car.

The Killing Flame Army explored this land every day to find medicinal herbs. Li Huaijin had often read medical books in the palace before and recognized that many of them were precious medicines.

Fang realized that there were countless medicinal herbs in the forest, but Qingque made a living by raising livestock and hunting. He was not familiar with Chinese classics and did not know medicinal herbs. He handed the herbal map he had drawn and some herbs to Su Heyan.

Mu Jinan stole a glance at him. When did he draw? Wasn't he with her every day? Could it be after he coaxed her to sleep at night? No wonder he looked so dark and tired.

The girl felt a little sweet in her heart, and was impressed by his cleverness. The herbal paintings were lifelike and vivid, with lots of colors.

Li Huaijin spoke much more slowly. Although Su Heyan knew some Chinese, some ancient characters were difficult to understand:

"In addition to trading horses, Youzhou's trade will also include trading in chariots, furs of minks, foxes, and wolves, kumis, and medicinal herbs."

"According to the Shennong's Herbal Classic, Fritillaria is used to treat fever caused by colds, stranguria, hernia, and astragalus. Astragalus is used to treat carbuncle, ulcer, pus discharge, pain relief, leprosy, hemorrhoids, fistula, and to replenish deficiency."

"Licorice can cure cold and heat evil spirits in the internal organs, strengthen the tendons and bones, and detoxify wounds and swellings. Long-term use can make the body lighter and prolong life. Deer antler can treat leakage, bad blood, epilepsy, and replenish qi."

"Cistanche deserticola, removes cold, heat and pain in the stem, strengthens yin and improves essence and qi, treats women's symptoms; musk, antelope horn, rhubarb, wild ginseng, etc..."

Su Heyan smiled from his stern face, recorded what Li Huaijin said, and translated it into Mongolian. He was impressed that Li Huaijin could remember thirty medicinal herbs without being a doctor, and he felt respect for him:

"If my people could also obtain the books and medical prescriptions in the Central Plains, learn etiquette, and acquire medical skills, my people would be in a different situation."

"It's just that adding more items requires the approval of the Emperor of the Central Plains and the court. I wonder if the King of Liang has approved it?"

Although Sake practiced medicine to save lives, he was unwilling to pass on his medical skills. When his tribesmen fell ill, there were very few doctors, and many of them died because they could not be treated.

Li Huaijin's eyes were gleaming, like bright lights, guiding the backward tribe to strive for the top:

"It's winter now and the herbs are sparse due to the snow. We will have to wait until next spring to collect them. I have my own plans. As for the collection of books, I will think about it later."

"You should select some intelligent and kind-hearted men and women from your tribe and have them learn the medicine charts first. When the time comes, there will be people to teach you the art of medicine."

Su Heyan was grateful. Zhongyuan was not a bully. He was giving all his knowledge to him. He was much more merciful than his fellow tribesman Sa Ke. He immediately stood up and bowed to Zhongyuan:

"I thank King Liang for his great kindness on behalf of my clansmen."

Li Huaijin reached out to help Su Heyan up, the young man's eyes were firm:

"Please stand up quickly, Lord Su, there is no need to be polite. Your clan and Sheng are one and the same. Our country must take care of the safety of our clan members and ensure that they live and work in peace and have enough food and clothing."

Su Heyan inexplicably felt an invisible and powerful force in his heart, like the power of an emperor. He was against war, but Li Yuanyang never listened to him. The young man lowered his eyes with a solemn expression:

"I know that there is a world of difference between one king and another. King Xi has tortured you so much, but King Liang is willing to take care of our people. I feel ashamed."

Li Huaijin patted his shoulder and smiled calmly: "This is all the princess's order. Your people should thank the princess."

Su Heyan saw Mu Jinan's clear eyes and immediately understood: "Yes, the clan members must know that the Princess of Shengguo is virtuous and repays evil with virtue."

Mu Jinan was stunned for a moment, and just as she was about to speak, Su Heyan had already left. She crossed her arms over her chest, looked at him with his head tilted up, waiting to be praised. She said nothing and deliberately gave him the cold shoulder.

The boy couldn't help himself, so he moved closer to her arm and asked, "Why aren't you talking?"

Mu Jinan held the pen and said, "You can't sleep at night? Don't you want your legs anymore?"

Li Huaijin sat beside her and ground ink for her, staring at her with burning eyes:

"want you."

Seeing that he was not serious, Mu Jinan held the inkstone tightly. The young man immediately grabbed the inkstone and smiled seductively:

"If you're beaten silly, who will give you advice, who will coax you to sleep, who will kiss you?"

Mu Jinan's cheeks puffed up as he thought of the modern times:

"If there is peace, the supply of horses will exceed demand, and the tribesmen will have difficulty exchanging them for silk, silver, rice, etc. The weak will survive, and they will want to plunder them. There is also an old grudge against An Xuan for abducting warriors. The Xi King has raised an army, and the Xique tribe will surely be united and share the same hatred for the enemy."

"If there is a war, horses will be in short supply and the high price will be unaffordable for us in the Central Plains."

"Huai Jin is very wise. This way, they will have more ways to make a living. It will not only help them solve the high price of horses, but also win the hearts of the people of the Qingque tribe."

The girl held his face in her hands, rubbed it, and turned away. Where the pen fell, dots of ink splashed:

"I heard that geniuses are prone to mental illness. Are you one of them? But you look normal. Let me make it clear, if you are, I don't want you."

The air in the tent seemed to be frozen, filled with an unsettling silence. Li Huaijin's eyes dimmed as he stole a glance at her face. Although he was joking, she looked extremely serious and determined.

His fingers trembled as he touched the embroidery on the girl's brocade sleeves. The boy withdrew his hand and stood up.

"The matter of ancient books still needs to be discussed with Emperor Su and the nobles."

The princess who married into a foreign country would bring with her treasures, golden saddles and jade bridles, seeds, works on construction and engineering, collections of books, medical prescriptions and treatises, etc.

However, due to the obstruction of Cui Hengling, Emperor Su only sent gold, silk and jewelry for this marriage, but no books, scholars or craftsmen. The collection of books brought by a princess who had previously married into the royal family had long been lost, and the craftsmen and scholars were all dead.

Mu Jinan sighed, knowing that he would have to pass the test of the court nobles. If he was discovered smuggling the rubbings here, it would cause trouble.

"I have offended the Lanling Xiao family and the Qinghe Cui family. Cui Hengling is now the prime minister, and the nobles follow his lead. The only one is the Fanyang Lu family, but they have no weight in the court."

Li Huaijin massaged his legs, looking painful: "Leave this to me, don't worry."

"what!"

His screams pierced her ears. She saw the boy fall to the ground, hugging his legs and rolling around. Mu Jinan felt a sudden pain in her heart. She threw down the pen in her hand and rushed to him:

"Huai Jin, what's wrong with you? Does your leg hurt?"

The boy's cheeks were wet with sweat, and he bit his lip: "It must be Sako."

Mu Jinan ran out of the tent, his eyes bloodshot: "Canying, Luosheng, go get Sa Ke, hurry up, the prince's leg is seriously injured."
