Although Yuangai Suwen knew that the Tang army led by Jingwen had a weapon that could explode, this weapon could be thrown directly by hand, and it was not complicated to use. Although this weapon is not as powerful as the Flying Thunder Cannon, it is more flexible. And these grenades are aimed at ordinary soldiers, so this power is actually enough. Therefore, the Goguryeo soldiers suffered huge casualties, but there was no good way. And Yuan Gai Suwen thought about breaking his head, and he couldn't think of any good way to break through this city.

In the original history, grenades were used to defend the city at the earliest, mainly for defending the city. And once the enemy uses a grenade, it means that there are huge casualties. In this case, the besieging side can only use artillery to bombard, but the saddest thing is that the Goguryeo side has no artillery, so that Yuangai Suwen has no way to attack the city. Anyway, Jingwen is using this kind of one-knife freshness to eat all over the world, but Yuangai Suwen has no choice. Jingwen used the enemy's weapons to be inferior to himself, and then bullied them hard, but they were beaten without any temper.

Yuangai Suwen knew that he had to find a way to conquer this city quickly, otherwise he would let the reinforcements of the Tang Dynasty come over next, and his 100,000 people would fall short. However, in the face of the absolute superiority of the enemy's weapon, what can Yuangai Suwen say? And Yuan Gai Suwen can only consider whether he can use some other means and some more out-of-the-way hands.

"City Lord Yang, do you know the layout of Anshi City?" Yuangai Suwen asked.

And Yang Wanchun immediately said: "Many of my soldiers also live in Anshi, so they are quite familiar. ”

"Okay, you can give us a rough layout of Anshi, and then we can consider attacking from underground. If we attack from underground, we will definitely be able to conquer Ann City, so that I can wipe your ass. Yuangai Suwen said.

"Digging tunnels?" Yang Wanchun was also a little surprised.

Yang Wanchun didn't expect Yuangai Suwen to come up with this method, that is, to dig a tunnel. However, this seems to be a non-reluctant, after all, if you attack head-on, you will inevitably have to face enemy grenades. Then attacking from the ground will be no problem. No matter how powerful someone's weapon is, can it still blow up to the ground? If you can attack from the underground, you can seize the city tower by surprise, and you can completely open the city gate, so that the 100,000 army will rush in. When the time comes, once the street fighting is fought again, it will be the Goguryeo troops who will win. Because the Goguryeo army was 100,000 people, and the Tang army was only one-tenth, even if the Tang army had advanced weapons at that time, it should not be the opponent of the Goguryeo army. Moreover, the Tang Army could not gain the support of the people, and it must be very dangerous to fight in the streets at this time.

"Yes. Even if you dig a tunnel. This time we are going to take the city by surprise so that we can be sure of victory. When the time comes, I must let Tang Jun see what our real strength is! Damn, you want to bully us with a few powerful weapons? At that time, once we seize their weapons, then we will also get them out, so that we will counterattack the Tang Dynasty and rob all the paintings in the Central Plains. Yuangai Suwen said excitedly, obviously he did not hide his ambitions in the slightest.

Yang Wanchun scoffed at Yuan Gai Suwen's statement, because let's not talk about whether the Tang Army can let you grab the corresponding weapons. Even if you take a step back and say that after grabbing the weapon. You can't necessarily make a copy, either. Even if you take a step back and say that you can copy it, then you will be able to capture the Central Plains? The Central Plains also has corresponding weapons, and it will still be a war of attrition. Is the population of Goguryeo enough to consume with the Central Plains? At that time, there will be more than 10 million people in the Central Plains, enough to drown their army of less than 200,000. So the capture of the Central Plains, this is just a beautiful dream, at least Yang Wanchun didn't dare to think about it. At that time, the Manchu Qing Dynasty was still a population of millions of soldiers, so they could have a chance to capture the Central Plains. But it was impossible for Goguryeo to be a soldier for all the people. After all, Goguryeo is actually a farming nation.

Therefore, Yang Wanchun, who knew his own situation very much, was very disdainful of Yuangai Suwen's idea of capturing the Central Plains, but he didn't say anything. After all, if you say anything yourself at this time. It's just that it can arouse Yuan Gai Suwen's disgust, and he won't give himself small shoes to wear when the time comes! Now Yang Wanchun is the general of the defeated army, and he has no status in the barracks, so it is not good for him to offend Yuan Gai Suwen, otherwise he will not have his own good fruit to eat.

However, Yang Wanchun also thinks that digging tunnels this time may be a good idea, after all, this can avoid direct confrontation with the enemy's grenades, which can reduce a lot of casualties. Even once the city is attacked, I am afraid that in such a hand-to-hand encounter, the enemy's grenades will not be able to be thrown without scruples. Moreover, there were many houses in the city, and it was impossible for the grenade to exert the maximum effect, so the Goguryeo people could gain a certain advantage.

However, will the Tang army give them a chance? As Jingwen's Tang Army, which has invested a lot of effort, where is it so easy for them to clean up?

Jingwen began to look at the tents of the Goguryeo army in the distance, and asked in surprise, "Why are they so honest?" Shouldn't they try to conquer us as best they can? If they're so idle, they really won't be able to conquer our city. Once our reinforcements arrive, they're really going to fail. Putting it off can only do us good, they don't know it, right? Yuan Gai Suwen and Yang Wanchun shouldn't be fools, how could they let their time go so far and not take any action? They want to trap us? This is simply impossible, not to mention that we have just delivered a large number of supplies, let's just say that our reinforcements will arrive soon, and they do not have the conditions to besiege us! ”

And Lin Fei was also very surprised and asked, "Yes!" How can they be so honest, this is not like the style of the Goguryeo people. Now we are the 'aggressors', they don't want to drive away the aggressors, how can they be idle if they don't want to get rid of the invaders? I think they definitely have a conspiracy here! ”

"What plot can they have? It seems that you have to be careful, don't accidentally fall into their way. Jingwen was also muttering.

"Division commander, minister, it seems that the military affairs department of our division has some news to report!" A herald said. (To be continued......)
