"The minister understands, and the minister will definitely do his best to do it." Zhang Nan nodded and said.

"That's the best, I am now clear about the power of this technology, so if Datang can get the help of Momen, my Datang soldiers and horses will definitely be more prosperous." Li Er raised his head and looked at the sky, as if he was imagining that under his wise and martial leadership, Datang would become rich and strong.

"Your Majesty, what you said is not bad at all." Zhang Nan nodded, Zhang Nan is still very sure of Comrade Li Er's consciousness and ability to accept new things, if Li Er does not have this awareness, it is impossible for the national strength of the Tang Dynasty to go up, and it is impossible to become one of the best dynasties in ancient times.

"Well, then you should do your best to prepare for this matter, this is what I came to you today, just to give you a guard who can protect you thoroughly, since you have already picked it, take it back, by the way, you also have a good rest in the house for a few days, don't run around." Li Er commanded.

"The minister thanked Your Majesty." Zhang Nan threw his hand at Li Eryi, Li Er waved his hand, signaling that Zhang Nan could take someone away, Zhang Nan left Li Er's palace, and took this escort given to him by Li Er to the Ministry of Industry, after all, Cheng Yanjin had something to do with him.

On the way to the Ministry of Industry, Zhang Nan also kept talking to this new guard, although he was likely to be an eyeliner sent by Li Er, but he still had to say what he should say, after all, he had to help him take care of the home.

"What's your name? Where are you from? Zhang Nan first asked his guard, and while asking, Zhang Nan looked at the appearance of this person, like Xiao Bai, he is the kind of person who will decompose if he falls into the pile, but there is a dangerous aura on his body.

"How many such people has Comrade Li Er raised?" Zhang Nan asked silently in his heart.

"Back to the master, in Xia Xiaosong, a person from Chang'an." Xiao Song's title is very fast, and it seems that he is also a person who can observe words and feelings.

When Zhang Nan heard this name, he was suddenly a little strange, and when he looked at Xiao Song's face, he did look a little similar to Xiao Bai. Zhang Nan asked strangely: "This, who are you Xiao Bai?" ”

"Back to the master, Xiao Bai is my younger brother." Xiao Song said with a smile.

Yes, they are still twins, and they are really destined to follow their brothers.

"Speaking of which, the younger brother was able to go to the military academy to serve, or thanks to the master's blessing, if it weren't for the lord's idea of establishing this military school, then the younger brother would probably have to stay in this deep palace like me. Xiao Song took the initiative to say while following Zhang Nan to the Ministry of Industry.

"It's all a small thing, but which of the two of you has higher martial arts?" Zhang Nan waved his hand and asked, although this question seemed very strange, Zhang Nan still couldn't help but ask, although Xiao Bai was only a member of Qianniuwei, but his combat effectiveness was still ranked among the people Zhang Nan had seen, of course, it was just fist and foot kung fu, if it was about immediate kung fu, Li Er's generals were much stronger.

When Xiao Song heard Zhang Nan's words, he immediately laughed, and then said: "We two brothers haven't studied martial arts for a long time, but the last time I learned martial arts, I, who was an elder brother, didn't spare a little hand, and beat him to lie on the bed for several days." The main thing is that I have a problem, once I start to do it, it is easy to be impulsive and can't stop. ”

After Xiao Song finished speaking, he scratched his head embarrassedly.

When Zhang Nan heard this, he suddenly felt powerless, why do you say this luck is so good? Not only did he pick out a twin, but his personal guard was still a violent person, which was not a good thing.

"Since your martial arts are higher than Xiao Bai's, why didn't the emperor let you go when the instructor was selected?" Zhang Nan asked strangely.

"The younger brother is Qianniuwei, and we belong to the emperor...... Well, Neiwei, so I wasn't in the emperor's consideration at that time. Xiao Song scratched his head. Although Xiao Song used the word "internal guard", Zhang Nan still guessed it, what internal guard is, it is completely nonsense, Xiao Song must be a dead soldier trained by Comrade Li Er, although the dead soldier is the most loyal guard.

But Xiao Song's loyalty is not for Zhang Nan, but for Li Er.

The two chatted all the way to the Ministry of Industry, although Xiao Song shouted a master, but there was no humility in the conversation, it was completely two equal people talking together, of course, Zhang Nan did not expect Xiao Song to be loyal to himself, as long as he could protect himself.

After a while, the two came to the Ministry of Industry, Zhang Nan stood at the door of his familiar office, thought about it, and asked Xiao Song to follow him in to see Cheng Biting Jin.

Cheng Yanjin was sitting on the side and didn't know what he was playing, but when he heard the movement, he raised his head, and when he saw that it was Zhang Nan coming, he said with a smile: "Qingquan, come on, come on, sit down quickly." ”

Zhang Nan responded with a smile, and then Cheng Yanjin saw that Zhang Nan was followed by a person, and Cheng Yanjin asked a little strangely: "Qingquan, who is this?" ”

"Oh, his name is Xiao Song, he is the elder brother of Xiao Bai, the chief instructor of the military academy, the emperor is afraid that I will have any accidents in the future, so he gave Xiao Song to me and let Xiao Song protect me." Zhang Nan explained.

Cheng Yanjin frowned when he heard that Xiao Song was Li Er's person, but soon, the frowning brow was soothed.

"Hey, originally I said to help Qingquan pick a few people with good fists and feet to go to where you are, but now it seems that the emperor is still thoughtful." Cheng Yanjin said with a smile.

"You said that you are the emperor's person, that fist and foot kung fu must be good, come and come, come and compare with the old man, it just so happens that the old man has been very hard recently, come on, try to compete with the old man." Cheng Yanjin looked eager to try.

After hearing this, Xiao Song immediately said: "Don't dare, don't dare, how dare you do it with the general." ”

When Cheng Yanjin heard this, his eyes widened, and he said: "It's not a big deal to ask you to practice, how can you be like a girl, grinding and chirping." ”

Cheng Biting Jin's agitation method is very inferior, so inferior that Zhang Nan can hear Cheng Biting Jin's meaning, but people who practice martial arts seem to hate others questioning themselves the most, Xiao Song seems to be the same, hearing Cheng Biting Jin say that he is a girl, Xiao Song's face immediately changed, and then said: "It's just to protect the safety of the master, if the general really wants to practice his fists and feet, then he will naturally accompany him to the end." ”

As soon as Cheng Yanjin heard that Xiao Song was fighting, he immediately said with a happy look: "Okay, okay, it's in the small courtyard outside, the old man wants to see how many taels of skills you have as a guard, let's say it first, if your skills are not good, the old man will go to the emperor to say it." ”
