After Zhang Fan first killed at least two Inner Gate first-class masters, and then seriously injured three of the remaining eight in the continuous street fighting, and the remaining five also suffered more or less minor injuries, the scarred remnant of the six five Inner Gate masters who could barely fight, finally began to realize the strength of this strange opponent.

"Although this person's body method and his own skills are only about the same as the masters of the outer gate of about six or seven grades, far less powerful than he expected before, but the attack method is extremely sharp, if it is encountered within ten zhang, it is almost impossible to dodge, and from reaction to combat experience, it is by no means comparable to ordinary people. Our top priority now is to stabilize our position, and it is not easy to attack for the time being!"

Hearing this, the other seven companions somehow suddenly felt a sense of relief, after all, in such an environment, it was very likely that they would completely put their own capital in this siege operation.

It was not the first time that Zhang Fan had faced a confrontation with many opponents in his previous life, so he only judged the situation he was facing at this time in an instant: if he took the opportunity to launch a guerrilla counteroffensive now, he would have a good chance of killing at least one more master of the inner gate who was injured and lost his combat effectiveness, but it would take at least two minutes or more.

Although the time of the many rounds of the battle from the fight to the present only lasted for more than a minute, it was not too short for the world's masters and even the cavalry and horse teams that rushed into the city. If the enemy's reinforcements approached, making it difficult for him to at least calmly not expose his body in this alley, then he would undoubtedly face unpredictable dangers in the face of multiple inner masters.

Therefore, Zhang Fan immediately launched a quiet but rapid retreat. Zhang Fan estimated that with his current strength, if he competed with the enemy's second-line masters from the sixth to eighth grades in a confrontation in a similar environment, he should be much calmer, and it was easy to easily kill such an opponent in the middle distance. Ordinary soldiers who encounter the enemy, especially those who are like the Four Kingdoms Alliance, whose martial arts level is worse than that of the soldiers of the Great Xia Dynasty, but with some enemy soldiers with strong bows and crossbows, in this street fighting environment, they may not need to use flying needles and hidden weapons at all, and they can also chop melons and vegetables just by relying on their own unique experience and skills and equipped melee weapons. Although the merit value against these enemies may be a little lower, it is the best way to influence the tide of battle in this situation.

In this way, at a slight distance from the central tower, the ordinary warrior battle formations of the four-nation alliance army, which were suddenly walking on the streets and alleys, began to encounter attacks one after another. Even at a distance of about seventy or eighty paces, there is almost no flaw.

Zhang Fan either launched a continuous attack from behind a big tree on the side of the street, or from the window of an ordinary house, restaurant, or brothel, and often fired three waves of at least six fifty sewing needles and a bundle of needles in two seconds, and only then did he evade under the cover of the shield and cover with the fastest way to escape under the cover of the shield and cover in the enemy's counterattack like a swarm of bees, or simply use the cover of terrain and features to escape.

In this way, there were nine successive attacks, and sixty-three people were killed and wounded under the fire of fifty-four syringes and two thousand seven hundred sewing needles. The physical endurance of these people is obviously much inferior to those top masters of the outer gate or the first and second grade masters of the inner door, of which eleven people were killed on the spot, and seven people were also seriously injured and died before effective treatment.

Zhang Fan touched his waist at this time, and even the "bullet belt" behind him, which was originally composed of countless syringes, after the consumption of this round of fierce battles, the proportion of at least one hundred and twenty syringes left was not too much, and in emergency considerations, Zhang Fan no longer planned to use these "big killing weapons", and began to approach in the direction of the city, to see if there was no chance to "abuse vegetables".

The so-called low-level black powder, based on the Chinese gunpowder in the Ming and Qing dynasties or the 14th-15th centuries in Europe, the processing capacity, storage capacity, and saltpeter quality of craftsmen are limited. Suppose the energy of each kilogram of firearm barrel is 200 joules. The initial kinetic energy of a single firearm does not exceed 1,000 joules, and if you follow the traditional idea of muskets, even in the face of not very good protection effectiveness will be greatly reduced (Wanli Aid War), only at close range will have a certain effectiveness. If the weight of the projectile or the amount of charge is increased, it will bring a great test to the soldier himself.

However, if it is not for penetrating the armor, but for blunt kills (anyway, in most cases, the opponent of the overhead novel does not have plate armor and other equipment with strong resistance to blunt hits), then 400 joules of energy is enough, which is equivalent to a 1-pound projectile flying to a height of nearly 100 meters, and the range of considering air resistance is estimated to be about 150 meters per hundred, or a projectile of 200 grams flying to a height of nearly 200 meters, and the actual estimated range is about 200 steps or 300 meters.

Combined with the demand for throwing error and seeking more battlefield shooting opportunities (the farther the distance between the two armies, the longer the actual confrontation stay), the latter is a more suitable choice.

When firearms are placed in the hands of minions without a decisive advantage over the crossbow in range, most people will not be able to play well because they are interfered with and suppressed. Therefore, it is more effective to concentrate on a small number of people who are braver and have better conditions for protection, and of course, it cannot be too few, otherwise it will be suppressed by the opponent's concentrated fire.

Therefore, the plan is also about to come out: a piano-like French artillery at the end of the Hundred Years' War. Because most opponents of the British army may not have the ability to protect themselves, they can be even more. For example, about 30 pieces of small mortar guns with two-kilogram barrels are placed on the launcher when they are loaded with ammunition, and the shield is bracketed to cover the loading personnel of the artillery crew. Four loaders and 1 gunner, the firepower that can be deployed in the effective combat time of the entire operation of 8 minutes is: 30 + 4 * 3 * 8 (small stubby firearms are easy to load and clean, and can be specially trained to reach 4 rounds per minute, and the actual 3 rounds per minute) about 126 rounds of projectiles. Assuming that the density of the opponent's forces within the attack accuracy range is 10 square meters per person, and the projection is 0.6 square meters, half of the projectiles that will be hit and all the ricochets will be protected or dodged, and the lethality potential is 4, which is comparable to that of the gunner.

Europe, which was fully developed after the 17th century, was different from China. Europe is mostly plain, mountainous and close to land and sea. The grassland cultivated land is abundant and extensive, and it is convenient to store grain. 10
