The county wall of Huixian County is not high, and even the height of a modern two-story building cannot be reached, only about five meters, but the thickness is more than four meters, and it is very easy to run horses on it.

Of course, such a Xiaxian city wall naturally cannot be compared with Chang'an, it is all tamped with soil, at most it is to add some glutinous rice juice in the middle, and fortunately, it is in the era when there is no explosives in the Tang Dynasty.

However, with the city wall at this height alone, he wanted to resist tens of thousands of troops, and if it weren't for Xue Wanche seeing the power of the explosives made by Li Chengming, he would definitely have to evacuate.

On the city wall, people came and went at this time, except for the soldiers guarding the city wall, the rest were the craftsmen and people who were nervously assembling the trebuchet.

Li Chengming is not a mechanical engineer, he is just an ordinary person, he only graduated from high school in modern times, he didn't even go to college, and he came out to work later and was very ordinary, and he didn't know much about trebuchets.

However, after a cursory look, Datang's trebuchet looks pretty good, the whole is about three meters tall and two meters long, and it looks very heavy.

"This trebuchet can throw multiple things at a time, and how far can it be thrown?" Standing in front of a trebuchet and looking, Li Chengming opened his mouth and asked Xue Wanche.

"Back to Your Highness, this trebuchet can throw about eighty pounds of heavy objects, and the farthest can throw about three hundred steps." Xue Wanche obviously knew the data of these trebuchets, and replied without thinking too much.

Li Chengming bowed slightly, generally satisfied with this data, after all, it was just a trebuchet, not a rocket, so it couldn't be too harsh.

Besides, with a range of 300 paces, it is enough to deal with those siege soldiers, after all, the distance of even the strong crossbow is only about 100 paces now, not to mention that they still have explosives, which is more than enough to defend the city.

"How many trebuchets are there now?" Li Chengming took his hand, walked to the female wall next to him, looked outside the city wall, and asked lightly.

It's just a lower county town, there is no complicated terrain, and there is no moat or anything, because there is no water source here at all, and even Chang'an has no moat, let alone here.

Although there are some peaks in the surrounding ten miles, they are all small hills, not high, and they are even more flat outside the county.

Well, it's good for a large army station!

Of course, in such a place, throwing explosives with a trebuchet is like a bomber, there is nowhere to hide.

"Back to Your Highness, in addition to the one hundred and fifty old planes before, only a dozen or so were driven out overnight last night, please forgive Your Highness!" Xue Wanche clenched his fists and pleaded guilty.

Naturally, it was impossible to blame Xue Wanche for this trivial matter, Li Chengming shook his head and said, "It's almost enough, the two city gates are more arranged, especially here." By the way, are you sure that Wei Chigong will lead his army to attack the city from here? ”

"Uh......" Hearing Li Chengming's words, Xue Wanche hesitated slightly, and then hugged his fists and said, "Your Highness forgives your sins, and the general is not completely sure." It's just that this time the commander of the army is Wei Chi Gong, the last general knows a little about this person, although this person is quite brave, but the character is arrogant and conceited, this time he led tens of thousands of troops to attack, he will definitely want to fight a full battle, so as to show his majesty in front of the traitor Li Shimin, and the east city gate is just where he came from, and the end will have six or seven percent certainty that he should take the city from now on! ”

Hearing Xue Wanche's analysis, Li Chengming bowed slightly.

For Wei Chigong, Li Chengming has also seen some of his past information before, although this person is listed as one of the twenty-four heroes of Lingyan Pavilion, and he is still the fifteenth hero of the Sui and Tang Dynasties, but the evaluation is not good.

is so happy, arrogant and conceited, relying on hugging Li Shimin's thigh, he has saved Li Shimin several times and has risen to the top, and has been favored by Li Shimin.

For example, in the Xuanwumen Incident not long ago, Wei Chigong rescued Li Shimin, who was almost killed by Li Yuanji, shot Li Yuanji, and then led his troops to directly break into the palace and hold Li Yuan hostage.

However, this person likes to make small reports, and whenever he finds out the mistakes of the eldest grandson Wuji, Fang Xuanling, Du Ruhui, Cheng Yanjin and others, he will directly accuse him in front of Li Shimin, and his relationship with others is not good.

Unless, Wei Chigong's ability to lead troops in history is not high, and there are many defeats, so I will not repeat them here.

"If you're sure, you'll be able to arrange it as you like, but don't relax the layout elsewhere." Since Xue Wanche said so, Li Chengming didn't ask any more, he also understood that nothing could be 100%, there would always be risks, and he pursued professional things to handle the best by professionals.

"Yes, Your Highness!" For Li Chengming's trust, Xue Wanche showed a grateful look on his face.

"How's the thunder, how many did Luo Ning send over there?" Although he plans to hand over the matter of city defense to Xue Wanche, it does not mean that Li Chengming is just a shopkeeper, and he still needs to ask about the things he should ask.

"Back to His Highness, the thunderstorm on Luo Bei's side has already sent over more than 300 bags, and the last general has secretly asked some soldiers to train to light fires and throw them." Xue Wanche said respectfully.

"Well done!" Li Chengming praised it appropriately, and then said, "What happened to the things that you buried before?" ”

Hearing Li Chengming's words, Xue Wanche immediately understood that what Li Chengming was talking about was a thunderbolt, two packs of two hundred kilograms of thunder, they had only tried ten kilograms of thunder before, and the power was enough to blow up a huge crater on the ground, Xue Wanche really couldn't imagine what kind of scene it would be if these two hundred kilograms of thunder exploded?

I'm afraid that I will destroy the mountains and rocks, and the sky will fall apart?

What's more, this time, there were many iron nails and iron filings added to the two thunderbolts, and if they exploded at that time, I thought of the clay pot pieces inserted into the trunk before......

It's chilling to think about.

"Back to Your Highness, the East and West General has been buried last night, there and there, respectively, the last general guesses that these two places should be the place where the traitors camp!" Xue Wanche looked at Li Chengming in awe.

Regarding this kind of thing about the garrison of the army, or Xue Wanche, who has passed through the battle array, Li Chengming just asked casually, and did not say much about his thoughts, and then asked, "How is the scout probing, Wei Chigong and Changsun Wuji are afraid that they know that we are here in Huixian, right?" ”

"Yes, Your Highness, the last general still left some people to confuse those traitors, but those traitors sent hundreds of scouts at once, and our soldiers were invincible, so they could only retreat, and also let Wei Chigong's traitors know the truth of our situation in Wannian County, and there were scouts outside the city last night, I am afraid that our news has reached the ears of Wei Chigong and Changsun Wuji." Xue Wanche lowered his head and hugged his fists.

Li Chengming looked into the distance, his eyes flowed, and then said, "It's okay, even if Wei Chigong and Eldest Sun Wuji receive the news, their army is inconvenient, I'm afraid that we won't be able to come here until tomorrow, at that time we have already prepared, just wait for the work, just wait for them to send the head of Xiang Shang." ”

"Your Highness is wise!" Xue Wanche also laughed.
