What Wu Nai took out was a long cloth wrap. He then opened it and took out a few arrows.

Liu Baoshuang was a little disappointed after reading it, and she asked Wu Nai: "What's wrong? Isn't it just an arrow? What's so strange about this?"

Wu Nai then pointed to the arrow, Liu Baoshuang looked at the arrow, and then showed surprise: "This ...... There's something wrong with this arrow......"

The arrowhead of this arrow is indeed strange, it looks like a bulging cicada chrysalis, with small holes leaking on both sides of the arrow, and it is made of animal bones.

Liu Baoshuang asked curiously, "What is this?"

Wu Nai picked up the arrow and pointed at Liu Baoshuang: "This is called Mingdi, which was originally used by the army of the grassland people to send signals, and was later learned by our Daxuan. ”

He Lou Pengfei hurriedly interjected: "That's right, this is indeed the system of Daxuan." In order not to be confused in the battle, Daxuan's Ming Di is a little different from Dinu, the two pairs of openings are to attack, and the four pairs of openings are retreating, and the soldiers are judged by the different voices of the commands. ”

"What the master said is right, you can see again. After Wu Nai finished speaking, he raised another arrow.

Liu Baoshuang looked at it and said, "This arrow is so strange! Why is the arrow so thick?"

He Lou Pengfei smiled after reading it: "Hahahaha, little sister deception, you don't know this, right? This kind of arrow is not only available to ordinary people, this three-edged arrow is called 'piercing steel arrow'." It's a great thing, it doesn't sway in the wind when it's shot, and the arrow is steady enough that if it's within thirty paces, it can easily shoot through heavy armor. I often ...... this thing Wait a minute...... This ......"

He Lou Pengfei was stunned when he said this, he snatched the arrow from Wu Nai's hand, looked at it blankly for a while, and then asked Wu Nai with a surprised face: "Wu Nai......!

Wu Nai looked at the colt and nodded with a smile: "Exactly, if it's just a Ming Di, it may just be a deserter." And this 'steel arrow' will only be issued by the military treasury according to the head before the battle, and after the battle, the rest must be returned, and those who dare to hide it privately will be dealt with by military law. So, this thing is not something that a horse thief can finger in. ”

He Lou Pengfei was so angry that he broke the arrow in his hand into two pieces, and roared angrily: "It's the other way around! These bastards! It's just bold! Wu Nai, you say, did Zhao Xing, the general who guarded Xiguan, send someone to assassinate us? Bringing the 'piercing steel arrow' is because we are afraid that we won't die!"

Wu Nai shook his head and said, "Master Ma is angry, can you listen to me first?"

He Lou Pengfei nodded, he took a deep breath and took a deep breath, which can be regarded as a fixed mind. Then he asked Wu Nai, "Then in your opinion, who sent this group of assassins, and who else can command the border army besides Zhao Xing?"

Wu Nai returned: "In my opinion, it should be that stabbing Shi Ding Xiuran." ”

He Lou Pengfei asked again: "Oh, how can you see it?"

Wu Nai replied while recalling: "Master Ma was not in the court on the day the urgent report was sent, so there is one thing you may not know. The urgent report was not sent by Xiguan Assassin Shi Ding Xiuran, but by the guard general Zhao Xing. ”

When He Lou Pengfei heard this, he felt that something was wrong, and then asked: "What? Is it Zhao Xingfa? He is a guard general, and he can only take charge of border guard affairs, how can he be involved in the matters reported to the table? Isn't he afraid of losing his head?"

Wu Nai returned: "That's right, and Ding Xiuran is the head of Xiguan, even if it is to be reported, it should be reported by Zhao Xing to Ding Xiuran, and then Ding Xiuran will report it." ”

He Lou Pengfei felt that it was wrong when he heard it, and then squinted at Wu Nai and blew unhappily: "Okay, okay, I know this, don't sell it, don't sell it, hurry up and pick up some key points!"

Wu Nai smiled, and then continued: "The reason why Zhao Xing acted beyond his authority was not that he did it on purpose. It was because Ding Xiuran had been secretly not reporting, so Zhao Xing had no choice but to make this risky move. ”

He Lou Pengfei thought for a moment, then patted his head and said, "Understood! Ding Xiuran, this bastard, should be holding some bad water? I was afraid that things would be revealed after we passed, so he sent someone to assassinate us!"

Wu Nai nodded after hearing this, and then added: "You know, he is now bold enough to dare to kill Yushi, then it means that this guy has other plans." I estimate that he is playing a big game this time, and he wants to use the whole Xiguan as a bargaining chip to do a big thing!"

He Lou Pengfei was shocked when he heard this, and immediately asked nervously: "What's the big deal!?"

Wu Nai didn't reply, just looked at the bright full moon in the sky and sighed: "Alas, I'm not sure about this...... But what is certain is that the thief is either prepared to attach himself to Dinu, or he is ready to establish himself as a prince. But no matter what the intentions are, Xiguan can't be lost. If this thief is not stopped, the Great Declarations will usher in a bloody storm......"

He Lou Pengfei said anxiously: "Then what should we do now? Hurry up and go back first to report to Your Majesty that there is a change in Xiguan?"

After hearing this, Liu Baoshuang just looked in the direction of Xiguan, which was close at hand, with an embarrassed face, and muttered to himself: "Brother......"

Suddenly, Liu Baoshuang's shoulders felt a burst of warmth, which made her feel a little stable in her troubled thoughts. It turned out to be Wu Nai, and he was gently pressing Liu Yushuang's shoulder with his hand.

However, Wu Nai didn't look at her, but continued to He Lou Pengfei: "Master Horse, in my opinion, it must be too late to go back and report now." ”

He Lou Pengfei hurriedly asked, "Why?"

Wu Nai pointed to the thief on the ground and said, "Master Horse, if he dares to send someone to assassinate us, it means that he is about to accomplish great things." At present, it is enough for him to resist our group of imperial histories. When the imperial court received the news of our death and sent the next group of imperial historians to investigate, I was afraid that after he was done, he would no longer be afraid of the imperial court. ”

After hearing this, He Lou Pengfei was even more anxious, and he asked again: "Oh, it's not to go, it's not to go!, so what are we going to do now!?"

Wu Nai said categorically: "Of course, we will continue to march towards Xiguan. ”

Liu Baoshuang looked at Wu Nai in surprise after hearing this, Wu Nai looked at her, just smiled and nodded.

Yes, don't worry, your brother and Daxuan, we all have to save!

After listening to this, He Lou Pengfei asked, "Is this ...... The four of us went to attack the city, and this is also ...... Anyway, it's too late! We have to fight hard! We can borrow troops from nearby prefectures and counties first! If they wear the same pants as Ding Xiuran, we will slaughter them, and then seize the local military power!"

Wu Nai laughed loudly after hearing this: "Hahahaha!

He Lou Pengfei looked at Wu Nai with a puzzled expression and asked, "What's the matter?" Do you still want to go to Ding Xiuran openly?"

Wu Nai smiled smugly and returned: "Otherwise?"
