Gao Ming felt that his painting skills were still relatively strong, not only painting well, but also painting fast, when Cheng Chuliang and Li Jing came out of the inner courtyard, he had already finished painting.

When Gao Ming put down the brush, Li Jing had already come to his side, and then bowed to him obediently.

"Qinghe has seen big brother!"

"Good!"

Seeing her polite appearance, Gao Ming suddenly smiled and nodded, and then beckoned to her again.

"Come, Qinghe, you come closer, I'll teach you how to wear this cow nose ring, by the way, do you know what the cow nose ring is?"

"Hmm!"

As soon as Gao Ming's words fell, Li Jing nodded.

"Just now, the husband has already told Qinghe that this cow nose ring is a kind of thing that hangs on the nose of the cow and can make the cow obediently plough the land!"

"Haha!"

Hearing Li Jing's answer, Gao Ming couldn't help but laugh at once, and nodded while laughing.

"Yes, that's roughly the case, but to be precise, it's because the cow's nose is the most sensitive and pain-sensitive place on the cow's body, so as long as you wear a hole in it and put a ring on it, then as long as you drag the ring, under the stimulation of pain, the cow will obediently plough the field under the traction of people!"

"Huh?"

Hearing Gao Ming's words, Li Jing suddenly showed a look of shock.

"Isn't that ...... Isn't it ......?"

Looking at Li Jing, who couldn't even speak clearly, Gao Ming knew what she wanted to say when he thought about it, so he immediately grinned.

"You want to say, 'Isn't that cruel,' right?"

"Uh......"

Hearing Gao Ming say what she wanted to say, Li Jing suddenly became a little at a loss, she opened her mouth as if she wanted to say something, but she didn't say anything.

Looking at Gao Ming's expression that seemed to be smiling, she suddenly blushed, and quickly lowered her head.

Seeing that Li Jing was suddenly silent, Gao Ming smiled slightly, and then gently patted her shoulder.

"Qinghe, brother knows that you are soft-hearted, but you must know that only by putting nose rings on these cattle can they become qualified cultivators, and then cultivate more land and grow more food, so that more people in the Tang Dynasty will not starve."

"Ploughing cattle?"

Hearing Gao Ming's words, Li Jing raised his head, and then looked at Gao Ming with some doubts.

"Big brother, don't these cows you just said know how to plow the fields?"

"yes!"

Looking at Li Jing's puzzled look, Gao Ming immediately nodded.

"These cattle are all cattle from the grassland, if they are not restrained by the cow nose ring, they will not be able to plough the fields at all, in that case, they can only be killed and eaten, because we Datang do not have so much grassland and grain to feed them!"

"I see!"

Hearing Gao Ming's words, Li Jing nodded.

"I understand, then big brother, tell Qinghe quickly, how to put nose rings on these cows, Qinghe hopes to turn these cattle into my Datang farming cattle as soon as possible!"

Seeing Li Jing's somewhat anxious appearance, Gao Ming suddenly smiled slightly, and then beckoned to her again.

"Come, you come closer, take a look at this picture I drew first, and then I'll teach you how to wear this bull nose ring!"

"Hmm!"

Hearing Gao Ming's words, Li Jing immediately came up, but when she saw the huge and deformed bull head painted by Gao Ming, she couldn't help but laugh out loud.

"Poof...... Big brother, you drew this...... Is this a cow? It looks so weird, hee-hee......"

"Uh......"

Looking at Li Jing, who was trembling with laughter, the corners of Gao Ming's mouth couldn't help twitching twice, and then he coughed twice in embarrassment.

"Ahem...... Big brother, this is an abstract way of drawing, don't care about these details, you have to focus on the nose of the cow, this is it! ”

Saying this, Gao Ming immediately pointed to the position of the cow's nose on the paper, and then nodded towards Li Jing.

"This is where the ring is attached to the nose, but be careful not to wear the nose ring too far forward or too back!"

"Neither too far forward nor too far back?"

As soon as Gao Ming's words fell, before Li Jing could speak, Cheng Yanjin, who was standing next to him, frowned.

"That's too much trouble, isn't it? I thought I could just poke a hole in the cow's nose! ”

"Hahahaha!"

Hearing Cheng Yanjin's words, Gao Ming immediately laughed, and waved his hand at him while laughing.

"It's not okay to poke a hole casually, because if it's too far forward, it's easy to pull the cow's nose, and then the cow will be wasted, but if it's too far back, it will avoid the most sensitive position on the cow's nose, and even if the nose ring is installed, the effect is not good!"

"Oh, I see!"

After Gao Ming's explanation, Cheng Yanjin immediately understood, but soon, he arched his hand towards Gao Ming again.

"Then His Royal Highness the Prince, where is the position of the suitable nose ring on this bull's nose?"

"That's a good question!"

As soon as Cheng Biting Jin's words fell, Gao Ming immediately gave him a thumbs up, and then nodded towards Li Jing and the others.

"In fact, the deconstruction of the bull's nose is similar to that of people, in the middle of the two nostrils, there is soft meat in the front and cartilage in the back, and the most suitable place to put on the ring is a little in front of the cartilage!"

"Cartilage?"

Hearing Gao Ming's words, Cheng Yanjin couldn't help but touch his nose, and then immediately showed a surprised expression.

"I touched it, and sure enough, there was a cartilage, just poke a hole in the front of the cartilage, is it okay? I understand! ”

Looking at Cheng Yanjin's expression of surprise, Gao Ming turned his head to look at the others again, and found that Cheng Chuhei, Cheng Chuliang and Li Jing all nodded, so he nodded with a smile.

"It's good to understand, but I also said before that the most suitable for domesticating a nose ring into a cultivated cow is only a calf that is one to one and a half years old, and the effect of a big cow may not be ideal, so I suggest Uncle Cheng that you first put a ring on the calf, and then the big cow!"

"Well, I see!"

Hearing Gao Ming's words, Cheng Yanjin immediately nodded with a smile.

"Most of the cattle from Xue Yantuo this time are not more than two years old, so Your Royal Highness the Prince, don't worry, is there anything else that needs to be done besides this?"

"Well...... this"

Hearing Cheng Biting Jin's question, Gao Ming immediately frowned and thought for a while, and then shook his head.

"The rest is nothing, wait for the cow to wear the nose ring, find a veterinarian to apply the injury medicine to the cow, and then let it rest for two days, and then take it out to try to obey the discipline, if you take it, it will be distributed to various states and counties, if you don't accept it, you ......."

"If you don't accept it, you will kill and eat meat, this old Cheng understands, hahahaha!"

Before Gao Ming's words were finished, Cheng Yanjin laughed again, and arched his hand towards Gao Ming while laughing.

"His Royal Highness the Prince, although this matter is assured to be handed over to the minister, the minister will definitely handle the matter for you, but if there is anyone who embarrasses the minister at that time, I hope His Royal Highness the Crown Prince can help one or two!"

"Haha, that's easy to say!"

As soon as Cheng Yanjin's words fell, Gao Ming immediately smiled and nodded, and then put his mouth to Cheng Yanjin's ear and whispered to him.

"When the time comes, you will do ......"
