This liquid explosive is liquid at a lower temperature. If the temperature is slightly higher, it is very easy to evaporate into a gas. Once these gases are mixed with air, they form an aerosol mixture with the air. This cloud-like substance explodes when it encounters fire. It has the power of explosion and produces powerful shock waves and huge pressure. It will consume a lot of oxygen during detonation, producing suffocating carbon dioxide! It makes soldiers within a certain range suffocating and suffocating and suffocating death due to lack of oxygen and being unable to breathe!

Fortunately, the defense system of Fort Woch is very complete, with trenches densely spread into the net, and each defense node has bunkers and castles, which are very strong, and the bunkers are connected to each other, making it difficult for this efficient killing cloud bomb to remove soldiers hiding in underground bunkers! After familiarizing with the principle of this suffocation bomb, the defense method is also very simple. Lean down, cover your mouth and nose with a wet towel, and wait for the air to flow naturally. Moreover, the bunkers and castles with doors are still very strong in defense against such weapons that do not directly kill people!

The position that Zhang Fan's team, who rushed to the front line, was also a high ground that was easy to defend and difficult to attack. There were only 9 people left in the replaced troops, and they were all injured! It is precisely because of the very good defense position of this high ground that this position can be held until now under the crazy attack of the German army!

With Zhang Fanliyadh and Patiguli supporting the Ringer Squad, more than 100 French soldiers came to reinforce, and reoccupied the trench and castle system and immediately rushed into the battle!

Akan and Wolf, the evil king Alimu, were both tactical masters, and immediately selected a blind spot to summon the armored castle of "Berta's Perseverance"! They lay on the armored castle on the ground like a turtle shell, and a shrinking howitzer turret extended its thick and short cannon barrel.

Howitzer is a kind of mortar. The ballistics are curved and the firing angle is very large. The shells fall parabola, with a large drop angle, and are close to hitting the target vertically! Therefore, their shooting will not be blocked by the line of sight. The place chosen by Akan and Wolf, the evil king Alimu, just guard the pass of a high ground and are in the blind spot of the viewpoint halfway up the mountain. The opponent's firepower cannot be covered by the mountain blocking.

The spiritual howitzer that can automatically find the enemy to fire spiritual shells every minute will not be blocked and can provide excellent fire support. If the German army advances, it will still be hit by the firepower of the castle! As long as other positions on this high ground are not occupied by the German army, the flanks of the "Berta's Perseverance" are not threatened, it will be as solid as a god!

The space inside the Iron Armored Burrow is quite spacious, and can accommodate 15 people to fight in turn! The Burrow has three shooting windows, in the shape of a font. Under the dome of the turtle shell, there are two shooting observation windows. Under the turtle shell, there is also an additional observation and shooting window, which can be seen further! If used for sniper or machine gun points, it can form a three-dimensional firepower network with the two shooting windows below!

However, except for Franken, the rulers did not carry out firepower strikes in the two shooting windows below. Instead, they were handed over to the four French machine gunmen who were charmed by the harp. Because the scene characters are the best choice to deal with the scene enemies. The attack power of their weapons and props will not be weakened by the scene. In an observation window above the castle, Xuanyuan Xing and another French sharpshooter were used together.

In this defensive battle scene, Xuanyuan Xing's sniping ability is the best to play. In the previous battles, he had shot dozens of German non-commissioned officers and earned a lot of merit and bonus points. The others were just playing soybeans. In addition to Franken's bonus to machine gun lethality, he could suppress the group charge of ordinary soldiers, and also earned some merit and bonus points.

There is not enough space in the castle. Yoda has already relied on the armored castle to summon his tribe and deepened the deep trenches around the castle. He has even expanded a relatively complete underground bunker to a lot. Most of the keepers of the decree rest here. However, the German offensive is very fierce now, and everyone can no longer make any moves. They are all lying in the trenches and shooting at the Germans. The mission prompts that everyone must hold on for 24 hours and may face more than five German attacks!

As soon as Zhang Fan and others gained their foothold, the first wave of attacks from the German army arrived. First, the artillery extension was prepared. The deafening sound of artillery lasted for five minutes, and the position was plowed again. The "Belta" turret on the castle was not outdone, and it also fired five spiritual shells to fight back! However, because of the distance, everyone could not evaluate the lethality of this turret.

Aken wanted to take a wooden kite to the sky to investigate, but he looked at the German planes hovering in the sky and retreated. Although the mission of shooting down ten German planes in the scene was to complete two of them, Aken knew that his wooden kite would definitely die in the sky. These German planes were even more terrifying than the poisonous bee "Qinyuan" on Kunlun Mountain! Only when the number of German planes was smaller, then pull up the flying carpet of the sacred dragon harp and Patiguli to go up and pick up the bargains.

Five minutes later, densely packed German soldiers gathered from a distance, and the rifle soldiers charged up while firing. There were fire spitting soldiers in the middle! The "Belta" cannon on the castle happened to fire automatically at this time, and a spiritual shell roared into the crowd of German soldiers!

The flames swept away immediately! Within fifty meters in diameter, there was no living person! But this artillery killed and killed more than 20 German soldiers. Moreover, the gap was instantly compensated by the German soldiers who rushed up! The scattered formation of the German attack was restrained by this firepower coverage. It can minimize the killing and consumption of artillery fire on the charges of dense personnel!

The clouds in the sky condensed into a black cross and slowly attacked the French positions. Zhang Fan and other rulers were each equipped with an M2 heavy machine gun from World War II! German soldiers were hit by spiritual weapons as soon as they entered the range!

However, the firepower coverage of the blue and green m2 machine gun props encountered a defensive barrier resistance outside the German formation! Just like the formation defense encountered during the battle in the Tang Dynasty. The attack momentum of these soldiers without shields actually formed a virtual image of a steel chariot covered with black gas, bounced away the spiritual bullet without hesitation!

Everyone was not surprised by this situation, so they had to put away the machine gun, pick up the gray rifle props from the World War I distributed in the scene, and shoot live ammunition. Just like ordinary soldiers, they must be loaded and retracted, which is very troublesome. But the shooting effect is still good, at least hitting the enemy can hurt them.

However, these weapons during the First World War were really not very good. The preceptors who adapted to the automatic attack of spiritual weapons were very unaccustomed to it! Everyone would rather fight at close range and be able to maximize the martial arts advantages of preceptors! However, when so many enemies charge forward, no matter how high the preceptors whose physical constitution is, they will face a terrible situation!

Fortunately, at this time, the French machine gunners in the armored castle opened fire! The bullets fired by the machine gunners actually had a kind light, which could break through the momentum barrier of the German soldiers' charge and shoot the steel chariots into pieces! German soldiers were shot and fell down. This is the power of the characters in the scene. They were actually worth five or six advanced keepers!

Franken's dark gold machine cannon also opened fire. The light golden spiritual bullets had the same power as the bullets of these machine gunmen. Many ordinary German soldiers were shot and fell down. Under the protection of the castle, this timid guy was like a fish in water and maximized his ability to strike long-range fire!

Among those followers of those scenes, only the red-haired pirate Rebecca from Zhang Fan's team and the Indian longbowman from Riyadh team can attack the enemy from a distance. The red-haired pirates can also summon one or two Caribbean pirates to help from time to time. This little girl is very suitable for this positional war.

French soldiers in other directions of the position also began to attack, and barrage formed instantly! German soldiers fell one after another in a pool of blood! However, because of the obstacles of the soldiers in front, the German soldiers behind continued to advance. Although the casualties continued to increase, they were getting closer and closer to the French positions...

However, the closer the distance, the more casualties the German army was, and every inch of advance was exchanged for the lives of soldiers! This is the terrible positional warfare! And when facing the complete trench and castle system, the casualties were further expanded!

But the French position was not safe. With the German artillery preparation, at least three sections of trenches were destroyed! The French army divided some soldiers to speed up digging, and Akenyoda and Riyadh also joined in. These alchemists also had bonuses in repairing defense projects, and the speed was much faster than ordinary soldiers.

"They are approaching..." Patiguli looked at the distance of the German soldiers and ordered, "We will fight back!"

A sound of elephant sounded on the French position, and then, a giant six-tooth elephant dressed in war armor raised up four hooves and rushed towards the German soldiers from the hillside! The bone spurs on their backs flew out and burst into the crowd! The Six-tooth Elephant King was a sharp weapon for the rushing battle! The phantom of the armored chariot condensed by the German army, dispersed under the impact of the Six-tooth Elephant King!

A huge tree man in the trench also quickly stood up, stretched his arms, grabbed a piece of the castle cement block that was bombarded, and threw it at the German positions! 100 death elves, flying arrows gathered like rain, and shot at the German soldiers who were broken by the Six-toothed Elephant King! These death elves with perfect arrows were like a hundred snipers. After the Six-toothed Elephant King broke through the formation, they showed great killing efficiency! In almost ten seconds, hundreds of German soldiers were shot and killed!

The Six-tooth Elephant King rushed around the German charge formation, but immediately encountered a threat! The German fire spitting soldiers scattered among the riflemen raised their flames and sprayed flames at the Six-tooth Elephant King! The defense power of these fire spitting soldiers is not high, but the attack power is super strong in the middle range!
