The reason why it stinks is because although the name of the gold juice is good, the thing it refers to is very smelly and disgusting.

In traditional Chinese medicine, gold juice refers to the addition of collected manure to the best well water or underground springs, and the soil is red soil. After multiple processes, it is buried in the ground for at least one year, usually twenty to thirty years later, to form traditional Chinese medicine.

This feces is also very particular, adults can't do it, it needs to be the feces of eleven or twelve-year-old boys, and the feces of a month before and after the winter solstice are chosen, because at that time people's physical condition is better, and feces are not easy to deteriorate.

The materials used to make gold juice in traditional Chinese medicine are very demanding, but there is no need for gold juice used to defend the city. Anything goes, as long as it's boiled feces and urine, it's called "golden juice."

But no matter whether you talk about it or not, it sounds good and disgusting.

This golden juice has always been an important offensive weapon for defending the city, and it is not only this kind of thing that will burn and burn the besieging enemy if it is boiled, because Shimizu can also do this.

The reason why gold juice is used instead of water is because it is dirty and can make the wounds of those who have been burned not good and even cause the plague.

This is something that Qing Shui can't do, and then a gold juice stench, even if there is no way to kill physically, it will hurt the enemy a lot in terms of smell, because the stench wafting in the sky makes people nauseous and vomit when they smell it, and the combat effectiveness will naturally be relatively reduced.

Compared with the price of fire oil, the renewable gold juice that can be found everywhere is really a necessary artifact for defending the city.

The defender of Dongbi Hucheng wanted to invite the Tang army to drink a pot of gold juice, but what he didn't expect was that these Tang troops led by Wu Yuanqing didn't think about a regular siege battle with them today.

Before, Wu Yuanqing didn't really want to use a lot of gunpowder, except for the routine artillery bombardment during the siege, he didn't want to use more gunpowder, because the quantity was the inventory on the ship, and if the large amount was used up, it would not be able to replenish it.

But now Wu Yuanqing wants to end all this as soon as possible, so he has to use a lot of gunpowder.

The reason why he personally brought the troops here was because only he had the right to order the unlimited use of gunpowder, and others like Liu Renyuan and Liu Renliang did not have this right.

When they were crisscrossing the seas in the South Seas, each ship was allowed to carry a certain amount of ammunition, because the imperial court knew that there were basically no opponents in the naval divisions at sea, and they would never need too many gunpowder shells.

In order to prevent the outflow of gunpowder or prevent the generals of the navy from concealing the gunpowder without permission, the imperial court not only stipulated the maximum amount of ammunition that each ship could carry each time they went to sea, but also secretly planted people on each boat.

Every time you go to sea, you will have a record of how many shots you have fired and how much gunpowder you have used, but if you don't have the right ones, you will definitely be severely investigated and punished.

This is why the emperor is relieved of Wu Yuanqing, so he issued far more ammunition to the sailors.

If it weren't for Wu Yuanqing to lead the troops, even if it was Zhang Liang who was originally planned to be in charge of the water division, Li Shimin would definitely not bring all the gunpowder transported to Langya County to the water division, but would let the water division run out and return to Langya in batches to replenish supplies.

This is also the reason why Wu Yuanqing personally led troops to attack Dongbihu City, because except for him, anyone who uses gunpowder must be cautious and cautious, otherwise the amount used afterwards is not right, it will be a big thing to do.

"Archer rocket preparation."

The 15,000 Tang army did not cut down trees to build siege equipment, nor did they put on a siege formation, nor did they even have the intention of setting up camp, as the defenders of Dongbihu City thought.

Instead, it puts out the sharp arrow formation commonly used in field attacks, and generally this formation is led by a fierce general in front of the assault formation.

I have never heard of this kind of formation in siege warfare, does the Tang army think that the soldiers defending the city on their side are all dead? Do you think that the gate on your side is open to the Tang army?

The defenders of Dongbi Hucheng couldn't figure it out, and they didn't know what kind of fools the Tang army generals were to do this.

Then he saw that in front of the formation, there were archers from the Tang Dynasty who began to assemble, and in front of the archers were a small number of shield soldiers holding improvised wooden shields.

As the archers advanced to the range of attacks that could be attacked by both archers, the Goguryeo archers defending the city were the first to shoot the arrows in their hands.

Jingle bell.

In addition to a small number of arrows that passed through the wooden shield and splashed sparks on the armor of the archer, more of them were stuck in the wooden shield and blocked.

After Goguryeo finished firing a round of bows and arrows, the archers on the side of the Tang army launched a counterattack, and the overwhelming rockets covered the area of dozens of meters to the left and right of the city gate.

This is not an offensive and defensive battle with attack power, but an offensive and defensive battle with defensive power.

All the soldiers on the Tang side wore full-plate armor or chain mail made of stainless steel, although the armor was not thick for lightweight, but the protection was far beyond the leather armor worn by the Goguryeo soldiers, and even many people did not have leather armor.

A round of Goguryeo arrows only injured a few archers on the Tang side, but the rockets that the Tang side fired back immediately emptied the Goguryeo defenders on the city wall dozens of meters around the city gate.

It can't be said that all of them were killed, a lot of them were killed, more of them were hiding behind the women's wall, and there were a lot of small flames caused by the sparks splashing on their bodies.

The Tang army's protection was high enough, so they advanced hard, the arrows did not stop, and the rockets whizzing and raining down pressed the Goguryeo defenders within a radius of dozens of meters of the city wall to raise their heads, and they couldn't show their bodies to fight back.

Dozens of meters away on both sides, because the distance between them is a little far, although the arrows can reach the Tang army, their strength is much weaker, and they can't make much damage to the Tang army protected by shield soldiers.

When the archers suppressed the Goguryeo defenders on the city wall, more than a dozen Tang soldiers came out and ran to the gate of Dongbihu City, which had lost its cover, carrying a large wooden box.

Lay, ignite, retreat.

At the same time, shield soldiers and archers are also avoiding on both sides.

Rumble.

After a loud bang of the heavens and the earth cracking, the gates of Dongbihu City were gone.

The Tang army, which had been prepared for a long time, rushed towards the city in an attack formation, and the people defending the city in Goguryeo were all dumbfounded, and they couldn't remember that the Tang army was coming for a while.

There are also reflections, but the area around the city gate is so large, the Tang army rushed into the city, and there were archers on both sides to suppress it, and the people who reflected it would be greeted by the Tang archers as soon as they shot one or two arrows at the Tang army's brigade.

In the era of cold weapons, it was a very difficult thing to siege a city, it was easy to suppress the defenders at the head of the city, but it was very difficult to break open the city gate with a siege vehicle.

Because it is impossible for the besiegers to suppress the defenders at the head of the city for a while, after all, the top is condescending, and once they can't suppress the enemy in the city, the rolling stones, sassal wood, gold juice, fire oil and so on come down, and the siege cart may not be easy to break because of the wrapped iron and cowhide, but the people pushing the cart can't bear it.

But this is not a problem at all when enough gunpowder explodes, just suppress it for a while, bury a large amount of gunpowder under the city gate, and one spark is enough to open the city gate.

From the time the Tang army came down to the city gate to blow up the city of Kung Fu, only a stick of incense passed.

Goguryeo's important city in the south, Dongbihu, was broken.
