Li Siwen turned his head to look at Li Yanran, the scene in front of him was really going to scare him to death.

If there were iron beads in it just now, I can't say that a few people would have died.

"The biggest secret of the dragon cannon is this, black powder, how about it?"

Li Yanran smiled slightly, now she knows that it is amazing.

"That's amazing!"

Cheng Chubi looked at the scene in front of him, and he was also shocked.

If this thing is used in the military, you can imagine what the situation will be.

One is still like this, if it is dozens or hundreds of them exploding at the same time, even if you are scared, you will be scared to death.

"Brother Li, can the power of this black powder be increased, if you can blow up the city gate or city wall at once, it will be too rebellious."

Yu Chihuan frowned, he now finally knew why this was Datang's top secret, such an artifact, if it was stolen by others, it would be a disaster for Datang.

"I haven't tried it, but as long as the dosage is sufficient, it should be fine."

Li Yanran really didn't think about these things, but she thought about it, if she really made a few explosive packs and blew up the city gate or the city wall, it should be no problem.

"Brother Li, you should immediately inform Xing Guogong, if you really fight with Tubo, this black powder should be a great artifact."

Li Siwen glared, if it was really like what Li Yanran said, those cities would no longer be a moat from now on.

The armor and weapons of the Tang Dynasty soldiers are the best in the world, if there is no convenience of the city wall, he can't think of any army that can be the opponent of the Tang Dynasty.

"Well, that's what you said, then invite Xing Guogong to come to the fiefdom, and let's talk to Xing Guogong well."

Li Yanran thought for a moment and nodded.

Now that the fire dragon cannon has just appeared, it will take a while to figure out the specific usage, but if he can tell the exploration of the future generations, wouldn't Datang be able to take a lot of detours.

"Let Xing Guogong come over the fief? Fear. I'm afraid it's not that easy. ”

Li Siwen frowned, although you are the princess of the Tang Dynasty, you are also a prince of the country, and you can be regarded as the top nobleman of the Tang Dynasty.

Although your face is big, people don't necessarily sell you this face.

"Don't worry, Xing Guogong will still give me this face!"

Li Yanran didn't hesitate at all, not to mention that she had the credit for recommending in front of her father, just talking about this fire dragon cannon, it was not something that Su Ding could refuse.

"Good!"

Li Siwen nodded and left directly.

"Alright, let's go!"

Li Yanran said and left with Li Feng with a wave of her hand.

Cheng Chubi, Changsun Yan and Yu Chihuan also followed behind.

"Sister, sister, I've forgotten people, I'm still here."

Seeing that everyone was leaving, they were still planting in the snow nest, and they shouted loudly when they saw this.

“？？？”

Hearing Li Hong's shout, Li Yanran also stopped, and looked at Li Hong who was struggling in the snow nest and was also stunned.

Damn, I almost left my little brother here.

It's really a fate.

Hurriedly ordered a few people to drag Li Hong out of the snow.

"Ahh Sister, you.."

Li Hong was so trembling that he couldn't even say a complete sentence.

"Okay, what such nonsense, get in the car quickly."

Looking at Li Hong's appearance, Li Yanran slapped it with a slap, when is it, and he is still talking nonsense there.

"Ahh Sister."

"Li Feng, plug his mouth and throw the car up!"

"Whoa."

Li Siwen rode his horse and galloped wildly, and came directly to Chang'an from the fiefdom.

"Who is it, do you know that the mansion of Xing Guo is ahead?"

Looking at Li Siwen on the horse, the part at the door stopped him in an instant.

"I have something important to ask to see Xing Guogong, and I want to report it!"

Li Siwen got off the horse and directly said his intention.

"The prince has an order, the expedition is imminent, no one will be seen, you better retreat!"

The trilogy glanced at the heroic Li Siwen, and didn't dare to say anything unpleasant, but just asked him to retreat.

"Do you know my identity?"

Hearing this, Li Siwen didn't do it, let's help you, who are you putting this score now, to show it.

Don't you want to be a national prince? It's the same as no one's house.

"No matter what your identity is, this is the Xingguo Mansion, not a grocery store, evacuate quickly, otherwise don't blame me for being ruthless!"

There was a hint of disdain in Buqu's eyes, what identity can you be higher than Lord Guogong?

I really don't know what to do with my identity to pressure myself.

"I am Li Siwen, the son of the British Gong, and I have something important to ask to see Xing Guogong."

Li Siwen looked at the trilogy in front of him and directly exploded his identity.

"Anglo-British duke? Xiao Langjun, please wait a moment. ”

Hearing Li Siwen's identity, the part was also taken aback.

The shadow of the famous tree, although they have been fighting with Su Dingfang all the year round, they still know Li Ji's name.

If Li Jing is the first god of war in the Tang Dynasty, this Li Ji is definitely worthy of the second god of war.

"Hmm!"

Li Siwen nodded, led the horse and waited there.

The trilogy came in and saluted Su Dingfang, who was drinking tea and reading a book: "Guogong! Someone asked to see him outside the house. ”

"Didn't the old man say it? I don't see anyone when the expedition is imminent, how many times do I have to say it? ”

Su Ding didn't raise his eyes, and after finishing speaking, he continued to look at the book in front of him.

"The prince of the country, the noble son of the British duke, said that he had something important to see."

The trilogy is also a period of depression, if it were ordinary people, I would know that I would send it away, but he is the little son of the national prince, and he can't afford to provoke it.

"The noble son of the English duke?"

Hearing the identity of the other party, Su Dingfang was also stunned.

Why did this Li Ji's son come to him? Do you want to go with the army?

"Take him to the main hall and wait."

"Whoa."

The trilogy retreated directly, while Su Dingfang tidied up his clothes and walked towards the main hall.

"Li Siwen visits Xing Guogong."

Li Siwen came in and saluted directly to Su Dingfang.

"Virtuous nephew, let's not be so polite, sit down!"

Su Dingfang waved his hand and motioned for Li Siwen to sit down.

"Nephew, what are you looking for me? If you want to go with me to the southwest, don't open your mouth. ”

Looking at Li Siwen on the side, Su Dingfang also spoke directly.

If you really want to go to the southwest battlefield with yourself to gild, then forget it.

After all, it was a battlefield, and this battle was likely to start against the wind, so he didn't dare to take Li Siwen to take the risk.

If there is something long and two short, he is afraid that Li Ji will fight hard with him.

"Xing Guogong, I am not here to go to the southwest battlefield with you, but Princess Lishan wants to invite you to Lishan for a trip and have important matters to discuss."

Li Siwen was stunned, I'm not stupid, why did I go to the southwest battlefield with you.

I knew that there was a disadvantage over there, and I went with you, wouldn't I have enough to eat?

Besides, if I really want to go to war, wouldn't it be better to follow my father, why bother with someone like you?

"Princess Lishan invited me to Lishan?"

Su Dingfang's brows wrinkled directly.

Li Yanran is the princess of the empire in the end, and it is not good for her, a foreign minister, to meet the daughter of the royal family.

But this time, he was able to lead the battle in the southwest, thanks to the recommendation of the other party.

"Virtuous nephew, why did Her Royal Highness the princess invite me to Lishan?"

After thinking about it for a while, Su Dingfang also asked Li Siwen with a smile.

"It's about the dragon cannon."

"Dragon Cannon?"

Hearing that it was about the fire dragon cannon, Su Dingfang also stood up directly.

Although the night sky was lit up by the moonlit night of the Spring River, the fire dragon cannon was what he cared about the most.

Although the fire dragon cannon has now been handed over to the Ministry of Industry for improvement, it is obvious that there is no hope for him to go to the southwest this time.

Now that this princess of Lishan has invited herself to the fiefdom, is there any other use for the fire dragon cannon?

"Xing Guogong, believe me, the fire dragon cannon is not only the kind of use you have seen, going to Lishan will definitely make your trip worthwhile."

Li Siwen smiled slightly, the fire dragon cannon is not just what you see.

That artillery fight alone is enough to make your jaw drop.

"In that case, then the old man will go to Lishan."

Hearing Li Siwen's words, Su Dingfang instantly made up his mind and went to the fiefdom to have a look.

Anyway, you won't lose a piece of meat if you walk around, isn't it just a waste of foot strength.

He also wanted to see what this princess of Lishan, who was so favored by His Majesty the Emperor, had.

"Okay, then I'll return to the fiefdom first and wait for the arrival of Xing Guogong."

Li Siwen stood up directly, bowed to Su Dingfang, and then left directly.

"Su Zhi."

"In!"

"Prepare the carriage immediately and follow me to the Lishan fiefdom."

"Whoa."

After Li Siwen left, it didn't take much time for Su Dingfang's carriage to leave the Guogong Mansion and head towards Lishan.

"Brother Li, fortunately, Xing Guogong will be here later."

After Li Siwen got off the horse, he came directly to Li Yanran and told the news of Su Dingfang's imminent arrival.

"Get ready to meet Xing Guogong."

Hearing that Su Dingfang was coming, Li Yanran stood up directly.

"Whoa."

It didn't take long for someone to report that Xing Guogong's carriage had arrived outside the town.

"Let's go!"

The people of Lishan, led by Li Yanran, came to the outside of the town together.

"Su Dingfang has seen Her Royal Highness Princess Lishan, and has seen Her Royal Highness the Crown Prince!"

Su Dingfang got out of the car and was stunned when he looked at the battle in front of him.

This is Princess Lishan for the fiefdom, why His Royal Highness the Crown Prince is also here.

"Xing Guogong, don't be polite, Yanran is young, you shouldn't be like this."

Li Yanran hurriedly helped Su Dingfang up.

"Your Highness!"

"Xing Guogong took the liberty to invite you over, he won't complain about Yanran!"

Li Yanran smiled at Su Dingfang and slowly confessed.

"Your Highness, I have tormented Su Dingfang, and I would like to thank you for recommending it in front of Your Majesty."

Su Dingfang looked at Li Yanran and hurriedly replied.

There are some things that must let people know their hearts, and I will remember your help, and it will be rewarded in the future.

"Okay, let's not talk about that, let's go inside!"

Li Yanran glanced at the state position, and her heart was also weak for a while.

If Wei Chi Jingde, Li Ji and Cheng Yanjin knew that they had recommended Su Dingfang, they were afraid that they would not kill him immediately and ask him for his guilt.

"Oh, it's the old man who is abrupt!"
