"Bang Bang ......"

At this moment, there were several loud noises outside, and an attendant entered the main hall: "Your Majesty, the fireworks have begun, do you want to go and see it?" ”

Yang Yu's eyes were full of light, his expression was about to move, he habitually looked at Li Yuan's position, empty, and then remembered that Li Yuan had retired.

So, Yang Yu looked at Li Jiancheng.

Li Jiancheng stood up with a respectful face: "Please move, Your Majesty." ”

Yang Yu then walked out of the hall happily.

Looking at the bright fireworks in the sky, Li Jiancheng thought about his father and brother who had left the table, and his eyes unconsciously glanced in the direction of the Wude Palace.

"Shizi, look at it, the fireworks are so beautiful."

The coquettish voice pulled Li Jiancheng's mind back, he turned his head to look at his wife, and replied absentmindedly: "Well, it's good-looking." ”

........

After the smoke cleared, looking at the deep pit where Zhang Yukuan was, Li Yuan and his son were shocked, and then looked at the deep pit where there was no grass, and couldn't help but sigh: "The lethality is really powerful." ”

Wang Kangda took out a smoke bomb and said to Li Yuan: "It's the same with this smoke bomb, just pull open the ring and throw it out." It has no lethality, it is only to block the enemy's view, and I don't think there is any need to show it again. ”

Li Shimin nodded and agreed: "Yes, that's right, don't waste it." ”

"Bring me a Flying Fish bomb." Li Yuan was still immersed in the shock just now, and wanted to delve into the Flying Fish Bomb, so he stretched out his hand to Wang Kangda.

Wang Kangda opened the box and pointed it to Li Yuan: "There is only one of each, and the Flying Fish Bullet is gone." ”

"Only one of each?"

Li Yuan's eyes straightened, and he scolded: "Didn't you say it earlier? No more demonstrations, just show me how to do it. ”

It's really, so violent.

Wang Kangda lowered his eyelids to hide the emotions in them, Xiao Yu'er was right, you can't tell Tang Wang that there is only one first, otherwise it won't be effective.

Next, Wang Kangda explained the operation method one by one the things in the box: "...... Actually, there was also a tear gas, but when we retreated, Xiao Yu'er used it. ”

It is even more unfortunate that their mission ultimately failed.

As soon as he heard the name, he knew what it was for, Li Yuan was silent and asked, "If these things fall to the ground, will they explode on their own?" ”

"No, these are improved, they won't explode on their own if they fall to the ground, only the ring pull piece can make it explode, and there's a short reaction time in between." Wang Kangda remembered the scene in Jizhou, and added: "However, the flying fish bomb before the improvement did explode when it fell to the ground, but now it will not, it is very safe." ”

Li Yuan showed a clear expression: "Okay, follow me back to the Wude Palace." ”

The group returned to the Wude Palace, Li Yuan waved away the inner servants, and only Li Shimin and Wang Kangda were left in the palace.

Li Yuan remembered the previous arrangement, so he asked: "Xiao Yu'er and that Wang Fubao sent you all the way out of Hebei, didn't you meet Yang Mao?" ”

"Nope."

"On the way back to Chang'an, you didn't meet it?"

"Nope."

Li Yuan's face sank, it seemed that Yang Mao was in trouble.

Li Shimin asked tentatively: "Did Aya send someone else to pick up Xiao Yu'er?" ”

"Yes."

Li Yuan nodded: "After I received the news, I sent Yang Mao to lead five hundred people to pick up Xiao Yu'er." ”

Five hundred?

Wang Kangda's expression flashed, if that day, they added five hundred more people, they should be able to bring Lin Zhiwu out of Hebei, right?

"What else does Xiao Yu'er have for me?"

Wang Kangda immediately took out two letters from his arms and presented them with both hands: "Xiao Yu'er wrote two letters, one is for King Tang, and the other is for the eldest grandson. ”

Li Shimin stepped forward to get the letter, flipped through it, there were really only two letters, frowned and asked, "Didn't you have a letter for me?" ”

His tone was slightly complaining, Wang Kangda suspected that he had misheard, and replied honestly: "No, only a letter to King Tang and the eldest grandson." ”

Li Shimin glared at him, turned around and walked towards Li Yuan.

Wang Kangda was a little inexplicable by that look, Xiao Yu'er only wrote two letters, what is the matter with him?

Even if he stared at him, he couldn't change the third letter.

Li Shimin presented both letters to Li Yuan, but Li Yuan only took the one that belonged to him: "The letter to the eldest grandson, you can take it back." ”

"Yes." Li Shimin then stuffed the letter into his arms and stepped aside.

Li Yuan opened the letter and read it.

“...... Presumably, Aya already knew that Lin Zhiwu was not an ordinary young man, and such talents must be used by Aye. Although the first operation failed, we did not come out of nothing, and I believe that Aya has received the blueprints and weapons that I sent back.

"That day, I overheard the news that Yang Guang privately sent a messenger to send a letter to Dou Jiande, inviting him to participate in the Shangsi Festival feast, and it seems that he also promised something in the letter, but I did not know the specific content.

"Later, I got news from the envoy that Yang Guang not only sent people to contact Dou Jiande, but also sent several envoys to meet various forces, I wonder if Yang Guang also sent envoys to meet Aya?

"According to my observation, Dou Jiande will definitely go to the Shangsi Festival feast, and at that time, I will find a way to go to Luoyang with Dou Jiande, and I will also find a way to let Lin Zhiwu accompany him, and then do it in Luoyang.

“...... Although this operation failed, the Xuanjia Army has made great contributions to helping me and protecting my safety, so please don't punish Aya and reward me......"

A feast on the Shangsi Festival?

Li Yuan closed the letter and thought for a while, there has been no envoy to Chang'an recently, could it be that the envoy from Luoyang is still on the way?

However, why did Yang Guang hold a feast for the Shangsi Festival and invite all forces to participate?

He thought that Li Mi and Liu Wuzhou would definitely not go.

Li Yuan opened the letter, read it again, and his eyes fell on a certain place on the letter, what did Yang Guang promise Dou Jiande? Xiao Yu'er said that Dou Jiande would go, which means that Dou Jiande is moved by Yang Guang's conditions.

Is it an alliance?

After thinking about it for a long time, Li Yuan couldn't determine what Yang Guang was thinking.

"Xiao Yu'er asks for credit for you, I will reward you tomorrow, you go down first."

Wang Kangda retired.

Li Yuan suddenly remembered something and asked Li Shimin: "Last time, Xiao Yu'er burned the outer city wall of Hedong City with fire, and then I ordered the city walls of all counties to be reinforced with bricks and stones, you are responsible for this matter, what is happening now?" ”

Li Shimin said: "A few days ago, various counties and counties successively submitted a note, saying that the city wall has been strengthened with bricks and stones in accordance with my father's requirements, and there will be no more cases where the outer city wall is stone. ”

"That's good." Li Yuan's gaze swept over the box, and he said, "Pass the order, and all the city walls will be strengthened by three layers on the original basis." ”

Li Shimin showed a puzzled expression: "Why is this?" ”

Li Yuan explained: "This flying fish bomb is so powerful, if there are more of them and concentrate on attacking, I am afraid that the city wall will be blown up."

"Of course, our walls are so thick that it's impossible to blow them up, so doing this is just a precaution."

"Xiao Yu'er's letter, you can also read it."
