As for the other soldiers in their rear, they were all blocked by the mountain, and before reaching the top of the mountain, they could not fire at all to support their comrades in front, they could only listen to the constant gunfire in front of them, and watch the corpses rolling down from the top of the mountain.

The position that the Captain Monkey of the Black Sledgehammer Regiment chose for them made them fight more and less to a certain extent, and the enemy troops who could fire at them at the same time were always the few who climbed to the top of the mountain, and if they fought more and less, even if they used flintlock rifles, there would be no problem, after all, the combat quality was there!

In this way, the Golden Eagle Empire attacked for more than an hour, and as a result, more than 20,000 people were killed, and it was not possible to capture such a hill.

After fighting for so long, he couldn't take a hill, and Agucos also felt a little impatient, and came to the front line regardless of the danger, listened carefully to the gunfire on the opposite side, and finally roughly judged the position of the enemy position.

But even if he judged the approximate location of the enemy, he didn't have a problem, because his heavy artillery in that position just couldn't hit it, and I have to say that the enemy general on the opposite side did have some ability, and in the absence of heavy firepower, he was able to come up with such a move to contend with him.

After returning to the rear headquarters, Agucos quickly gathered his generals and pointed out the approximate location of the enemy position on the map.

The other generals were also dumbfounded when they saw this position, after all, when ordinary people set up positions, they must give priority to those commanding heights! For example, on the top of the mountain, who would choose such a place to arrange a position!

However, the opponent used this trick to make his own heavy artillery become an ornament, and let his attacking soldiers only play into a disguised tactic of adding fuel, and the first group of people who rushed up the mountain was killed, and they could not effectively pose a threat to the enemy's position at all.

In order to prevent his soldiers from being sent to death, Agucos had already stopped the attack at this time, and then after discussing with his generals, he decided to send out fierce beasts such as steel-toothed rats and iron-scaled pangolins to break through the mountain, and then through this penetrated passage, the soldiers were secretly transported to the other side of the mountain, and then launched an attack from behind the enemy, so that the enemy army could definitely be defeated in one battle.

Seeing that the enemy had suspended the attack, they hurriedly seized the time to eat and rest, while the regimental commander of the big horse monkey returned to the rear to discuss the military situation with several other regiment commanders.

The big horse monkeys are not stupid, and after some discussion, they all feel that the other party is likely to use cave attack tactics next, so they are ready to send some soldiers to patrol back and forth around the mountain, and report to the top immediately if they find anything unusual.

In addition, the possibility of enemy troops attacking from both sides of the mountain should also be guarded against, after all, although both sides of the mountain are muddy swamps, ordinary soldiers cannot pass, and those martial arts masters with excellent light skills are exceptions.

Therefore, the monkeys gathered the only remaining machine gun bullets in the troops, arranged two heavy machine guns on the main roads up the mountain on both sides of the mountain, and immediately fired with heavy machine guns once they found the enemy. The mountain road was so narrow, it was enough to have these two heavy machine guns to defend it.

It seems that in order to hide the true intentions, the enemy's attack started again after a pause, but this time they can all feel that there are many fewer elites among the attacking enemy troops, and more are those cannon fodder beasts, such weak chickens They are naturally more pressure-free, and the black sledgehammer even divided the troops into three shifts, each squad is responsible for holding on for eight hours, so that the soldiers can take turns to get time to rest, It will not be exhausted by the enemy's continuous offensive with this continuous attack.

In this way, the armies of the two sides once again stalemate on this hill.

It wasn't until one night two days later that a soldier of the Blue Dragon Empire, who was in charge of patrolling the mountain, faintly heard a faint digging sound under the ground, so he hurriedly reported the discovery.

In addition to this soldier, several soldiers have also discovered this situation, and found different locations, it seems that the enemy army is also very cunning, it is estimated that digging tunnels in multiple different locations, so that in addition to increasing the success rate, more soldiers can be transported to the other side of the mountain at the same time.

It's a pity that the big horse monkeys have been on guard against this for a long time, so this tactical initiative of the enemy army cannot succeed.

Soon, several teams of soldiers were ordered to the locations where signs of enemy digging tunnels had been found, and were responsible for monitoring the situation.

Speaking of which, the Golden Eagle Empire was able to open several tunnels through the entire mountain at the same time in such a short period of time, which was also very powerful, and if they faced other enemy forces, they might really be caught off guard by their move.

The soldiers of the Golden Eagle Empire who were responsible for digging the tunnel did not rush out of the tunnel after the tunnel was opened, but first cautiously scanned the surrounding area to make sure that there were no enemy troops around, and then covered the hole with weeds and retreated back into the tunnel.

When they appeared again next time, they would definitely come with a large number of soldiers, and the big horse monkey was waiting for this moment.

After all, the most important thing in the battle between the two sides is to kill and injure the enemy's living forces, so the big horse monkeys did not destroy these tunnels directly after discovering them, but planned to wait until the enemy army gathered troops and entered the tunnels before launching an attack, so that they could wipe out all the enemy troops who entered the tunnels.

The soldiers of the Blue Dragon Empire, who were in charge of monitoring the situation at the entrance of the cave, immediately reported the news after seeing the enemy army emerging again through binoculars.

Then the next second the enemy soldiers were unlucky, and a grenade was thrown directly into the tunnel.

In the panicked screams of the enemy soldiers, these grenades exploded violently, killing all seven or eight soldiers near the tunnel entrance at once, and only a few of the more clever enemy soldiers at the front of the line escaped from the tunnel in time and survived.

But these enemy soldiers who managed to get out of the tunnel only survived for a few more seconds, and soon a large number of bullets came at them, knocking their bodies into a sieve on the spot, and they died neatly.

After that, several Qinglong soldiers took a large pile of poisonous weeds prepared in advance, lit them, and threw them into the tunnel.

Before the surviving enemy troops in those tunnels could figure out what was happening in front of them, the poisonous smoke from the burning of poisonous weeds quickly spread through the tunnels.

In the dark tunnel, the vision was already greatly affected, and by the time these enemy soldiers discovered these poisonous smokes, these poisonous smokes had already become very thick, and the poisonous smoke inhaled by the soldiers of the Golden Eagle Empire was also quite numerous, and they all began to foam at the mouth, and they had no strength to crawl out of the tunnels again.

By the time the poisonous smoke came out of the other side of the tunnel, about half of the soldiers in the tunnel had been poisoned, and most of the rest had fallen into a coma.

When Agukos found out that something was wrong and pulled out the soldiers closest to the tunnel entrance, they found that the soldiers closest to the tunnel entrance were already foaming at the mouth with poisonous smoke and rolling their eyes.

Tens of thousands of elites have not had time to exert their combat power, so they were poisoned to death in the tunnels with grievances, which made many generals of the Golden Eagle Empire feel very depressed, and even feel a trace of frustration, after all, they have been blocked by the small hill in front of them for several days, and tens of thousands of elites have also been lost here, as for the loss of fierce beast cannon fodder, I am afraid that there are already hundreds of thousands.

To make matters worse, early the next morning, the first reinforcements from the Blue Dragon Empire also arrived.

To be precise, this is a supply force, responsible for escorting all kinds of supplies to the front-line troops, most of the soldiers in it are those undead soldiers, these guys will not be tired, and they are the most suitable for escorting various supplies for long distances.

And this supply force of more than 5,000 people, in addition to sending all kinds of conventional supplies, also brought a new type of equipment.

That's a tank, and it's a steam-powered tank! There is no way, now the Blue Dragon Empire lacks those high-level workers, so the equipment that is too sophisticated and high-tech cannot be mass-produced, so it can only be produced as much as possible to produce those stupid and black equipment.

In order to be able to fit the huge steam-powered boiler, this thing is very large, about 25 meters long and about 7 meters wide, and its equipment is also extremely heavy, the average thickness of the armor is about 60 millimeters, and the frontal armor of the turret is 120 millimeters thick.

In addition, this thing still takes the multi-turret route, as if it wants to recreate all kinds of crooked ways in the history of tank development on the Orlan side.

Its main turret is located in the middle of the hull, equipped with a 120 mm caliber long-barreled gun, and there are four secondary turrets distributed in the four corners of the hull, each equipped with a 40 mm caliber rapid-fire machine gun, this thing was actually originally an anti-aircraft gun on a battleship, but this thing could have been used for both high and flat purposes, so it can be installed on this tank after a little modification, which can be used as a secondary gun or as its anti-aircraft firepower. Finally, there are the coaxial machine guns on the top of the five turrets and the heavy machine guns located around the hull, these fifteen mm caliber heavy machine guns are actually extremely powerful, it is enough to strafe those enemy infantry, five of which are coaxial machine guns on the turret, one in front and one in the rear of the hull, two on each side of the hull, a total of nine.

With so many guns mounted on top of such a tank, combined with its heavy armor, the Demon Destroyer I is a completely mobile steel fortress.

Since they have not yet been tested in actual combat, not many of these tanks have been manufactured, and only seven of them have been sent to the front line this time.

However, this is already making the big horse monkey and other senior officers ecstatic, after all, the power of the tank, they all know very well, especially in this other world where this kind of weapon has never appeared, once these seven tanks appear, they can scare those enemy soldiers half to death just by scare.

With these seven Demon Slayer tanks, they were completely sure that they would recapture all those lost positions.
