Cheng Hong and his entourage of four people quickly entered Chang'an, and Li Tai was choked all the way! Li Tai ran away like this! After getting off the horse at the palace gate, I can't take a step!

As he walked, he chattered: "This is too sinful!" Cheng Hong, can't you change the saddle? If you march in a hurry to fight, you won't let the horses die......"

Cheng Hong agreed, and Li Chengqian's eyes stared at the shot put grenade held by Zhang Yuanli! Li Tai saw that everyone ignored him, so he won't say anything! The four of them went straight to the Lizheng Palace!

When I arrived outside the hall, it was rare that Li Er didn't handle official business today, and he was teasing a parrot, I heard that Feng Ang came to pay tribute! will say: "Datang Wansheng!" Li Er loves it very much!

After hearing the movement, he looked up and saw Zhang Yuanli holding a grenade, and the two Li Chengqian brothers and Cheng Hong followed behind, laughing: "Qingque is back?" Yesterday your mother was still talking about you!

Wei County is not far away, often come back to see! Don't let your queen mother worry! There is also the bank Du Ruhui, who has complained to me several times! Except for the account room sent by the Wei Wangfu in the middle of the month, I can't see you at all! ”

Li Tai scratched his head after hearing this, and after stepping forward to salute, he said, "Aren't I studying trains!" Luoyang's coins are always insufficient! The horse-drawn railway vehicle is not heavy enough! And Cheng Hong said that the group of craftsmen were full of mud, and they could make mistakes when they drew good drawings! If you don't stare at it, you can't do it! ”

Li Er raised his hand: "Okay, don't talk to me!" Wait a little while your mother will come back, and you will talk to your mother! I see how you prevaricate!

And you! Little skin monkey, how long has Li Yu and Li Su been handed over to you? How long has it been since the last time they said they were on vacation and let them come back for two days? Do you think your mother's board is broken? ”

Cheng Hong hurriedly arched his hand: "Don't dare, don't dare!"

"How dare you! Tell me what happened this time? ”

Li Tai hurriedly said: "Father, Cheng Hong and I have researched a kind of gunpowder in the past two days!" It's not a problem to open mountains and crack rocks, and siege the city and pull out the village at your fingertips! Isn't this researched to be good news to my father! ”

Li Er laughed: "What is the use of this medicine?" Is it poison? Father told you, these two armies still have to fight with real swords and guns! Drugged little Doyle, it's not worth mentioning! ”

Here Zhang Yuanli said: "Holy Lord! What King Wei said is true, he just ordered one in Wei County, Cheng Shilang, the minister has seen it, if it is a three-zhang radius in the military array, it is difficult to have a living mouth! Sizhang still has the power to hurt the enemy! ”

Li Er said with a straight face: "Really? Is that the thing you're holding in your hand? ”

Zhang Yuanli lowered his head: "Exactly!"

Li Er immediately handed the parrot aside: "Cheng Hong, quickly demonstrate!" Let me see! ”

Cheng Hong looked around: "If you go back to your father's words, there is no way to demonstrate it around here!" Place is too small! It's not good if you hurt your father! ”

Li Er laughed: "I have killed more than a hundred times in the battle array, who can you hurt with such a small iron ball?" It's over, it's a big deal!

Zhang Yuanli hurriedly persuaded: "Holy Lord, this thing is not small!" It's like thunder on dry land! The ministers have just withdrawn sixteen or seventeen zhang, and their ears are still ringing! It's better to change places in the saints! ”

Here, Li Chengqian and Li Tai also persuaded.

Li Er waved his hand: "Okay, according to you, go!" Go to school! ”

The group came to the palace school, which is a place for the princes to learn martial arts! There are a few guards dedicated to the Pope's sons here, and the place is not big, and there is a row of arrows next to the wall!

The guards hurriedly saluted when they saw the emperor coming in, and Li Er waved his hand: "No courtesy!" Get out of here, all of you! "The guards have retreated!

Li Er looked at Zhang Yuanli: "How do you get this medicine?"

Zhang Yuanli glanced at Cheng Hong, and Cheng Hong hurriedly took the grenade! Glancing around, he hit the arrow stack next to the wall and asked, "Father, where is the arrow stack?"

Li Er glanced at Zhang Yuanli, and Zhang Yuanli hurriedly said: "Outside the arrow battlement wall is the Taiye Pool!"

Cheng Hong nodded: "Father, I'll put this thing in the middle of the arrow stack in a while!" Father, you have to retreat to the school gate! Zhang Guard, my father's An Wei Ke will depend on you for a while! ”

After Cheng Hong finished speaking, he passed over with a big grenade and a fire fold!

I went to the wall and took a look at it! Sure enough, behind the wall was a big pond! Lotus leaves have been spread all over the pond! Look outside! Fortunately, even if the wall collapses, I am not afraid of crushing people!

Cheng Hong put the grenade in the middle of the arrow stack! Blow the fire fold red! This time, the lead was specially brought by Cheng Hong, and it was five meters long!

Gently put the fire fold up, and the familiar "snort" sound sounded again! Cheng Hong ran back with his legs!

This time the lead was long enough to run to the door and still have time to plug your ears and look back! Li Tai and Li Chengqian immediately followed Cheng Hong's appearance, and also raised their two hands to plug their ears.

Here, I haven't waited for Zhang Yuanli to remind the emperor to block his ears, "Bang"! With a bang, the dust is flying! There was chaos in the arrow stacks, and several arrow stacks near the grenades were blown up and thrown high! If you are a little farther, you can get out of the distance!

Li Er was frightened: "Ah!" With a bang, and then stared blankly at the arrow stacks! Rubbing his ears and looking at Cheng Hong!

Cheng Hong led with one hand: "Father, let's see the effect!"

"What? What did you say? "Li Er plucked his ears!

Cheng Hong said it again, and Li Er heard it clearly! Zhang Yuanli and Cheng Hong took the lead, Li Er and they followed behind, and when they arrived at the arrow battlement, Li Er took a closer look: Okay! The whole piece was blown up in a mess, and even the ground was blown up into a pit the size of a pot!

The red palace wall on the opposite side was bombed with potholes and black spots all over it! The arrow stacks are even more unsightly, and even a few of them that are lucky enough to stand have been pierced by broken nails through several small holes!

Li Er looked carefully! After looking at it for a while, he asked, "How much does this thing cost?" Can it be manufactured in large quantities? Who knows the secret ingredient? ”

Here Li Tai stepped forward: "The cost is not high, the manufacturing is easy, the formula is given to Erchen by Cheng Hong, and no third person knows except Erchen and Cheng Hong!"

Li Er nodded: "That's good, let's go!" Back to the Imperial Palace! After saying that, he hurried out!

I just walked to the door and met the eldest grandson queen who was coming in with a blue face! When I turned around, I saw Li Tai's eyes lit up, and then his face sank again, and after greeting the emperor, he walked to Li Tai's side in three steps and two steps!

Li Chengqian, Li Tai and Cheng Hong hurriedly saluted, and before they could say half of the salute, the eldest grandson queen came to her side! With two hands and one ear, Cheng Hong and Li Tai twisted the salute and didn't go on!

"Two stinky boys, you can endure it, right? This is still in Chang'an, you say! How long has it been since you said hello! And you, Cheng Hong! I heard that you didn't even go home anymore, say! What are you busy with? Why are you so busy?

Qingque, do you want to be hit by the board again? I went for months, and I didn't even care about the bank! You are the governor of the bank, and you don't even know how many depositors you have now!

Cheng Hong, you threw it all to Lizhi over there in the Women's Street, right? I haven't seen anyone for several months, and Li Yu and Li Su, let you teach, not let you detain it, last time I said that I would go back to the palace on vacation, what about people? ......" chattered and preached, and from time to time they lifted their ears!

Cheng Hong and Li Tai grinned in pain and screamed in a low voice! Li Chengqian peeked at the side, Zhang Yuanli looked away, and Li Er was dumbfounded!

After a while, Empress Changsun was tired and said enough, took a breath, looked up and saw Li Er looking at her dumbfounded, and her face flushed: "Holy Lord, the concubine has lost her temper!"

Li Er stood stunned for a while: "It's okay, it's okay, Qingque is purely a disaster, Cheng Hong's punishment is light!" Cheng Hong rubbed his ears...... If you have your own children, there will be no disaster!

Empress Eldest Sun looked down left and right, and suddenly remembered something and said, "Shengshang, just now the concubine heard a dry thunder that seemed to come from the schoolyard, what did Shengshang see just now?" After speaking, he looked at Li Er with an inquiring face!

Li Er said: "It's not a dry thunder, it's just a weapon made by Qingque, it's not small, and it's the same as a dry thunder!"

When Li Tai heard this, he said, "It's Cheng Hong's secret recipe, which we invented!"

Cheng Hong covered his head! Pig teammates!

Sure enough, Empress Eldest Sun glared at Cheng Hong: "Sure enough, all the strange things are in you, and the board will be written down for you first!"

When Li Tai heard that he was going to beat Cheng Hong's board, he shrunk his neck!

Here Li Er shouted: "It's time to fight!" But let's wait a minute, let's go to the Lizheng Hall first! ”

Here, Empress Changsun went back, and the group came to the Lizheng Hall from the new!

Li Er took the secret recipe handed to him by Li Tai and looked at it carefully: "It's that simple?"

Li Tai nodded!

Li Eryi slapped the table: "That's a good ......"

"Report!" Before the words fell, there was a loud roar outside!

Everyone looked up in the direction of the temple gate! A sergeant was holding a red feather envelope!

"Report! Yumen Pass 800 miles expedited! Gao Chang is not a minister, he wants to see the wealth, smashes the envoys and the caravan, and kills the envoys for rape and robbery!

So that the minister Hou Jie escaped, 500 chasing soldiers chased to the Yumen Pass, General Hou led 80,000 troops to clear the chasing soldiers, did not return for three days, Zhou Sima is afraid that there will be a change of 800 miles to hurry up to ask the saint to decide! ”
