"Lord Wang, this is the deployment map of their Goguryeo people's ten thousand arrows piercing their hearts, and it is probably in these positions. You see, when the time comes, it will be issued to the commanders of those artillery, so that they can see how to aim and bomb them. This time we're going to bomb them with precision, and then completely ruin their nightly respite. Jingwen said.

"But can we destroy their hearts with all the arrows that pierce their hearts? We weren't able to see their crossbows, they were all covered, covered inside the walls. If we bomb like this, will it have no effect? Li Xiaogong was also a little puzzled.

"Don't worry, as long as the bombardment reaches the outside of the city wall, those explosions are enough to shock them to death! And ten thousand arrows piercing the heart will also be shattered! Jingwen said reassuringly.

Of course, Jingwen knew that the power of this flying thunder cannon was very huge. The power of the Flying Thunder Cannon is very great, even if it is not killed by the explosion on the spot, and the people who are not far away will be shocked to death and injured by the explosion. And those enemies will also find that when these soldiers die, they are bleeding to death, so those enemies say that this cannon is a cannon without conscience. And if it weren't for the fact that this kind of artillery is too limited, I'm afraid it would have been able to be popularized in large numbers. It's just that the rate of fire is too tricky, and the range is too close, there is no development potential, and it can only be used to siege cities, otherwise the army of the future may be equipped with a large number of equipment.

However, these were not problems for ancient China, and the short range was also relative to later generations. However, the range of 400 meters was already very far in ancient times, so this is not a problem. And Datang is only going to use it for siege, not for field battles, so they are not afraid that any enemy will hurt these cannons.

Now it is necessary to use these cannons to bombard those equipment that pierce the heart with thousands of arrows, so that the Goguryeo people will have a much more difficult time defending the city. The reason why the Goguryeo people believed that they could defend the city was that there were thousands of arrows piercing through the heart of this kind of terrifying defense facilities, otherwise they would not be so confident. But if it is destroyed now, I am afraid that the morale of the Goguryeo people, which is already low, will be greatly reduced again, and then it may collapse.

"Everybody's optimistic. These distribution maps, we knock them out one by one. The artillery commander of the Shenji Army said.

And the troops of those flying thunder cannons immediately began to divide the labor, and then prepared for battle. At present, the Shenji Army has more than 40 flying thunder cannons, and according to the calculation that there are about 50 10,000 arrows piercing strong crossbows on the wall of Goguryeo, it will probably be divided into five times before the bombardment can be completed. Because when the time comes, four cannons will be needed to "serve" a strong crossbow with 10,000 arrows piercing the heart, so it will naturally take five bombardments.

"Fire!"

"Boom Boom Boom Boom ......"

One cannon bombarded the city according to its intended target, and the explosive packets fell under the tower. Those ten thousand arrows piercing the heart were not placed on the top of the tower, because they were embedded in the city wall, so they could not adjust their aim, so they were placed under the tower. This makes it easier to shoot at the enemy. But now the Tang Dynasty has also borrowed this method to bombard the ten thousand arrows piercing the heart and strong crossbow under them, so that they can also bomb them, so as to blow up their ten thousand arrows piercing the heart.

"Boom!" "Boom!"

A burst of explosions rang out, and the huge shaking immediately shook the soldiers hiding in the hidden cave inside the city wall to the point that they were bleeding from seven holes, and then immediately remained motionless, apparently dead. And those Goguryeo's ten thousand arrows pierced the heart, and they all began to be damaged one by one, and then gradually lost their effect.

"What's going on? What happened to ten thousand arrows piercing the heart? The Goguryeo officers asked.

"Your Excellency. These ten thousand arrows piercing the heart have been destroyed. The soldiers operating inside had all been killed by the Tang Army's weapons, and the ten thousand arrows pierced through the heart were also shattered. You see, these are broken everywhere, and this kind of thing is very delicate, and even the slightest damage will not work. So ......"

"You mean ten thousand arrows piercing the heart have been ruined?"

"Yes!"

And Jingwen looked at the puff of smoke and dust rolled up by those cannons. Immediately knew that ten thousand arrows pierced the heart, no matter what, it was destined to be destroyed. Such a huge vibration was enough to destroy all those devices. After all, Jingwen also knows that the more sophisticated the equipment, the more delicate it is. And once this kind of precision equipment is touched by something. That can cause problems for a variety of reasons. The power of this kind of ten thousand arrows piercing the heart is certainly huge, but Jingwen can also judge it through the knowledge of physics and mechanics in later generations, and these things can be said to be very sophisticated. Such sophisticated equipment. It's also very difficult to maintain. Therefore, it is impossible for Goguryeo to be maintained at any time, and as long as the Tang Dynasty army continues to fire this explosive package, the damage of these ten thousand arrows will become bigger and bigger, and finally it will be impossible to maintain.

"Hmph, the cost of an explosives package is not too high, under the assembly line mode of production, less than three hundred yuan. But if you have a thousand arrows through your heart, the cost of manufacturing and maintenance is very high. And we blew it up in one go, and wiped out all your strongest combat power, look how arrogant you are! Jingwen snorted.

Jingwen knew that combat also had to pay attention to cost, although these cannons looked quite expensive, but as long as they could destroy their most powerful firepower, it was enough. The most powerful firepower of the Goguryeo people is that ten thousand arrows pierce the heart, which can be said to stand at the peak of ancient cold weapons. But cold weapons are cold weapons after all, and in front of Jingwen's firearms, they are all not worth mentioning. However, if there is no Jingwen, maybe they will still be able to hold it for a long time, after all, the army of Datang is still an army with cold weapons without Jingwen, and it will suffer heavy losses.

"Okay, the next thing is to see how long the Goguryeo people can hold out!" Jingwen snorted.

Without this kind of ten thousand arrows piercing the heart, the Goguryeo people may not be able to hold on for too long, so Jingwen doesn't care about the Goguryeo people at all. Next, if you want to see whether the Tang Dynasty attacks Goguryeo or forces Goguryeo to surrender, this is also up to Li Shimin's plan. If you want to attack, then I am afraid that Goguryeo's resistance is very low. However, forcing them to surrender is not completely unworkable, because now the king of Goguryeo, Gao Jianwu, is actually the people's heart, if he increases the pressure a little, then I am afraid that there will be contradictions within them, and maybe there will be civil strife! At that time, Pyongyang, the capital of Goguryeo, may not be able to fight without a fight. (To be continued......)
