In the face of everyone's doubts, Chen Keqiao explained: "Yes, it is blasting, thanks to Your Majesty's guidance, we have come up with a new plan to break the city, that is, to advance to the bottom of the city wall by digging tunnels, and then detonate a large amount of gunpowder to directly blow up the city wall."

"Is that possible? Is gunpowder powerful enough? Do we have so much gunpowder? As soon as Chen Keqiao's words came out, everyone asked many questions in a row!

The fact that they are asking so many questions also proves that they care about whether this tactic works or not!

If it is the same as what Chen Keqiao said, you can directly collapse the city wall of Wuzhou City through the thing called what, oh, called blasting, then it means that this Wuzhou City has been torn open a huge opening, and the follow-up attack will be easier.

If it's really feasible, then let alone Wuzhou, they can also play this way in siege warfare in other places, but if Li Xuan knows that they want to play like this in other places, Li Xuan will definitely spray them with saliva, Nima's, do you know how difficult it is to blow up the city wall with black powder, even if it is not to mention the technical difficulties, but how much black powder is needed, do you know?

That's not a few taels or a few catties, but a large amount, make so much gunpowder to blast, it's okay to play once, but playing a few more times will make the Tang Dynasty bankrupt!

Li Xuan had long thought about attacking the city by blowing up the city wall with gunpowder, but he had never had the opportunity to use it before.

Now, in the face of Wuzhou, which is as hard as a hedgehog all over his body, Li Xuan decided to play a civil fortification tactic and let those defenders in Wuzhou know that even if they hide behind the city wall, they will still be finished!

However, even a few days ago, Li Xuan still had many concerns, first of all, it was difficult to accurately measure the blasting point, and secondly, there was too much gunpowder needed, and the gunpowder in the Tang Dynasty had always been a first-class and scarce strategic material, but he was not extravagant enough to take it out to blow up the city wall.

In the Tang Dynasty, where all kinds of materials were in short supply, and sulfur and saltpeter were extremely scarce, every tael of gunpowder was made at a great cost to purchase raw materials, which was worth a lot of money.

On weekdays, in order to meet the supply of guns and artillery to the troops, it is extremely difficult, and Li Xuan is honestly reluctant to blow up the city wall.

The city wall is not an ordinary wall, the thickness is generally several meters, and the higher city wall is even more than ten meters thick at the base.

The amount of gunpowder needed to blow up the city wall is quite a lot!

However, after the scale of the Tang Dynasty expanded, the production of this gunpowder also gradually increased, although it was still not enough, but it was a big deal to divert the daily use of some troops.

It costs a lot of gunpowder, and there is even a great possibility of failure, but it is better than tens of thousands of dead and wounded!

So after thinking about it for many days, Li Xuan decided to dig a tunnel and place explosives for blasting, which is already the easiest way that Li Xuan can come out after thinking hard, and the success rate is also the highest, otherwise, it really depends on human life to gnaw, and when Wuzhou City is defeated, the first army may be completely abolished.

At this time, Major General Chen Keqiao also successively explained the principle and detailed plan of how to use gunpowder to blow up the city wall, and a group of people no longer objected after listening to it.

If a section of the city wall can be blown down, the city defense of Wuzhou City will be tantamount to being torn through a big hole, and the army troops of the Tang Dynasty will be able to quickly enter it, as long as they dare to fight in the future, there is still a great chance of taking Wuzhou City.

In the past, the Tang Dynasty had only tried to bombard the city wall with heavy artillery, and also tried to directly dig tunnels to send troops into the city to raid, and even played with digging tunnels and then using the weight of the city wall itself to collapse.

But after fighting with the Ming army for a long time, they really didn't dig tunnels directly to blast under the city walls.

However, there is also a problem, this digging tunnel, and it is dug under the city wall, the Ming army is not stupid, it must be able to find out.

Don't doubt it, the movement of digging the tunnel is not small, it is possible to find it when people lie on the ground and listen carefully, in the past when the battle of Liuzhou Fucheng, the Ming army found it many times, and then dug the tunnel in reverse and sent the dead soldiers down to re-block the tunnel.

However, the solution to this Chen Keqiao is very simple, excavate at the same time, send multiple groups of people to dig multiple tunnels at the same time, so that even if the Ming army discovers part of the tunnels and destroys them, as long as one excavation is successful, then the whole tactic can be successful.

As for the fact that some people will be killed or injured in the process of digging tunnels, this number of casualties is not worth mentioning compared to the huge casualties caused by climbing the city wall and storming.

In addition to digging tunnels, the trenches are also trying to match the digging of a place only a few tens of meters away from the city wall, and at the same time, the troops must also be prepared for a strong attack.

When the time comes, whether the walls are blasted or not, the troops will need to launch a strong attack!

Therefore, all kinds of equipment needed for the siege need to be prepared in advance, and the assault troops must also be prepared!

At this pre-imperial strategic meeting, Li Xuan directly bypassed everyone's discussion, and decided to adopt Chen Keqiao on the spot, in fact, this was his own strong attack plan, and then ordered all troops to prepare for this!

Li Xuan didn't need to take care of the preparation of the troops, and the generals of the Tang Dynasty Division would naturally arrange the combat readiness of the troops under his command.

For example, Chen Keqiao was personally responsible for the excavation of the tunnel in the engineer battalion and raised a large amount of explosives at the same time, while a group of staff officers of the Operations Department calculated the amount and location needed to blast the city wall, and thought about how to seal and detonate the city wall to successfully destroy it.

Instead of a crumbling wall, you'll see an oversized firework!

As for Li Xuan, he naturally has his own affairs to be busy, and this matter is not a trivial matter, on the contrary, it is still a major matter, that is, the regularization of the Liuzhou Independent Regiment, and even the formal inclusion of the Tusi Soldier Corps into the system of the Tang Army.

The predecessor of the Liuzhou Independent Regiment was the Tusi Soldier Force, which was formed by the convergence of dozens of Tusi families in Liuzhou.

During the Battle of Liuzhou City, Li Xuan gave this unit the title of Liuzhou Independent Regiment, which consisted of three battalions.

After entering Xunzhou Mansion and Wuzhou Mansion in the east, it accepted some of the soldiers of many Tusi along the way, and therefore added an infantry battalion.

Today, the Liuzhou Independent Regiment has four battalions under its jurisdiction, with a total strength of about 1,600 troops.

And after seeing the fierce death of these Tusi soldiers, Li Xuan had long wanted to completely take this army into his pocket, and then reorganize it into a storming force.

In the early stage, the army was successively dispatched as liaison officers, and when the fourth battalion was added, officers were sent to serve as deputy officers of some units, and regimental staff officers were dispatched.

In the past few days, Li Xuan has also been planning how to reorganize this army!

First of all, this unit must be used as a fist force for attacking, otherwise it will waste their fearless nature.

Secondly, they must be given good defensive equipment, that is, armor!

These Tusi soldiers are not the ordinary soldiers directly recruited by the Fourth Infantry Brigade, although those ordinary soldiers are more courageous because of the fierce folk customs, but they still cannot be compared with these Tusi soldiers.

For example, after the Huaiyuan Cen family re-became the Wuxuan Tusi with the back of the army, they generously sent more than 80 soldiers who had been trained by their family for many years to the Liuzhou Independent Regiment.

If it weren't for the fact that they were loyal to Li Xuan, they wouldn't have sent these elite soldiers, if it weren't for the fact that these soldiers were all elites, they wouldn't have made up so many toasts in Guangxi, and finally made up such 1,600 people.

The soldiers recruited under the Ming army are not as strong as the soldiers in the Liuzhou Independent Regiment!

These people have excellent martial arts, extraordinary courage, and are not afraid of death, they cannot be used as ordinary troops, let alone sacrificed at will.

Didn't you see the hundreds of people who were killed and wounded in the Battle of Liuzhou City before, and they can't be replenished now.

Then tactically they will not copy the regular army, because the discipline of these soldiers is that there is no discipline, and if they are forcibly restrained, they will cause their rebellious mentality.

Therefore, Li Xuan is preparing to make a special case in this Liuzhou Independent Regiment, and this daily military discipline is not so strict, as long as it can be seen, of course, the battlefield military discipline is still extremely strict.

At the same time, it is also to equip them with all kinds of troops, heavy armor sword and shield soldiers, heavy armor spearmen, light armor sword and shield soldiers, light armor spearmen, and archers, and give them the best cold weapon equipment, as for firearms, as a positioning as a hand-to-hand combat attack force, they mainly cooperate with the main force in the war, and they do not need these things, so it is impossible to equip firearms.

After thinking about it for two days, Li Xuan directly issued a holy decree to officially include the Liuzhou Independent Regiment in the establishment of the Tang Army, and all the officers and men of the regiment were transferred to active soldiers in the Tang Dynasty, and Cai Erhu was sent to serve as the head of the regiment!

As for the original Tusi Regiment Commander and the Tusi officers at all levels, those who are willing to be transferred will be transferred, and those who are unwilling to go back home, whatever you want!

The officer's affairs are easy to arrange, but the arrangement of weapons and equipment is a little difficult, they already have this sword and spear, there is no shortage, but this armor is not easy to solve.

The equipment of armor is needed by all the troops of the Tang Dynasty, so it has always been in short supply, and the troops themselves are too little, so they can't take out the extra armor to support the Liuzhou Independent Regiment.

In this regard, Li Xuan personally ordered the transfer of some armor from various units, from the third garrison brigade and the fourth garrison brigade, and also from the sixth infantry regiment, which only had a group of recruits, and there were no muskets, and some armor was transferred from the main force of the sixth infantry regiment, which had no muskets and was worrisome in combat effectiveness.

Then he squeezed from the Ordnance Division and other troops, and finally let Li Xuan squeeze out three hundred pairs of armor to equip the Liuzhou Independent Regiment.

And the number of armor is not small, after all, there are only 1,600 people in this Liuzhou Independent Regiment, except for archers and lightly armored sword and shield men and spearmen, basically heavy armor sword and shield men and heavy armor spearmen can get the armor they need.

And Li Xuan spent a lot of effort to arm this Liuzhou Independent Regiment, naturally hoping that it could play a major role in the upcoming Wuzhou Offensive Battle, this battle, the Liuzhou Independent Regiment will be the pioneer together with the two assault battalions drawn and formed by other units of the Tang Army, and will take the lead in attacking the city!
