As time passed, one monster after another fell to the ground. The officers and men on the northern wall were now extremely excited by this good result. Everyone is shooting like crazy. The Heavy had already replaced more than one barrel of the heavy machine gun they controlled. And the soldiers guarding the other walls all looked at their comrades on the north wall with itching at this time. Because of the eccentricity of the monster, they can only look at others with small eyes now.

However, at this time, there were two people whose brows were tightly furrowed. They are Sun Houguang and camp instructor Lao Li. The helicopter that had just been released had already reported to Sun Houguang again, and the second wave of monsters was not far from the outpost camp. But look at the current outside the northern wall of the camp, there are at least thirty monsters still desperately rushing towards the camp.

"Old Sun! Almost, let them come up! Looking at the monster outside the wall, Lao Li suggested to Sun Houguang again.

"Okay!" Although he was unwilling, Sun Houguang also knew that he couldn't delay it any longer. Glancing at the monsters outside the north wall, Sun Houguang adjusted the frequency of the headphones, and then ordered loudly: "Attention of the first special attack team, go up to the north wall!" The rest of the agent team is ready for battle......"

Although Sun Houguang decided to use small-caliber mortars and rocket launchers, Sun Houguang only cautiously used the first special attack team. As for the other three special attack teams, Sun Houguang didn't want them to go to the wall. Really, he didn't dare.

The special attack team is a heavy firepower team composed of all the "four zeros" and "small six zeros" in Sun Houguangji's outpost camp. Sun Houguang has formed a total of four such teams. Each team has 12 "40 Fire" and 12 "Little 60". As for the purpose, it is to supplement the PF98 120mm anti-tank rocket launcher to attack such a giant monster. It can be said that these four special attack squads, like the PF98 120mm anti-tank rocket launchers distributed on the four walls, are the last trump card in Sun Houguang's hands. Originally, Sun Houguang wanted to use these big guys again when facing that kind of giant monster. It's just that now, Sun Houguang was forced by the situation in front of him to use a special attack team in advance.

Following Sun Houguang's order, a team composed entirely of PP93 60mm mortars and 40mm rocket launchers climbed the steps to the northern wall. This squad was followed by dozens of logisticians with ammunition boxes on their shoulders.

The members of the 1st Attack Team moved quickly. In a few moments, the players were all squatting in the attack position.

"Smack! Syllable! Syllable! ……”

The lids of the ammunition boxes were opened, and the loaders removed the mortar shells or rockets from the boxes......

"Reload! Target coordinate correction! Preparation...... Put! ……”

"Tom! Tom ......"

With the order of the leader of the first special attack team, one mortar shell after another made a hollow "tom" sound in the barrel of the 60 mortar, and then shot into the sky with a sharp whistle.

At the same time that the mortar shells shot into the sky, the deputy squad leader of the 1st Special Attack Team also gave the order to fire to the twelve bazooka launchers. For a moment, "Huh! The sound of sneering ...... came and went. The tail of the "Four Zero Fires" carried on the shoulders of the twelve bazooka launchers spewed out long lines of flames.

"Boom! Boom ......"

In the sound of explosions, monsters were hit by rockets and shells fired by "Four Zero Fire" and "Little Six Zero". In the blink of an eye, a terrible howl rang out one after another among the monsters outside the northern wall.

Watching the monsters being blasted into the air in a miserable howl, Shun Houguang's face smiled again. Although I don't know how many monsters can be killed by the first wave of attacks, there is no doubt that at this time, these monsters in front of me have been completely blocked by the first special attack team. If this continues, the death of these thirty or so monsters in front of him is only a matter of time. Assuming the hell doesn't run away, of course.

With the orders of the two captains and deputy leaders of the first special attack team, the explosions in front of the northern wall continued one after another. And at this moment, the voice of the pilot of the helicopter who was in charge of monitoring the second wave of monsters in the distance came out again from the headset that Sun Houguang was wearing in his ear.

"Report to the battalion commander, the second wave of monsters has entered the intended location! Coordinates: XXX:XXX......"

Hearing the sound coming from the headphones, Sun Houguang's face, who was still smiling just now, suddenly turned pale. It's time to come, and it's finally here.

Without hesitation, Sun Houguang's left hand quickly adjusted the frequency of the headset again, and then ordered loudly: "Heavy mortar attention, the target has arrived at the predetermined location, coordinates XXX:XXX." ”

"Yes! Coordinates XXX:XXX......" Sun Houguang's voice had just disappeared, and a sonorous voice in the headphones immediately repeated the coordinates he had just reported. And as the voice shouted out the coordinates, the shooters of the forty 120 mm heavy mortars in the outpost camp quickly moved. In a short breath, the secondary correction of coordinates has been completed.

And on the city wall north of the outpost camp, hearing the sonorous voice in the headset, Sun Houguang gritted his teeth, and suddenly ordered loudly: "Regardless of ammunition, cover shooting!" ”

"Yes! Cover shot, without counting ammunition! In Sun Houguang's headphones, the sonorous voice repeated the order he had just given again. At this time, next to the forty heavy mortars of 120 mm caliber in the camp, the loaders had already loaded mortar shells from the rear of the mortars into the chambers......

"Ready! Put! ......" As an officer threw down a small red flag in his right hand, forty heavy mortars of 120 mm caliber let out a dull sound one after another. Dozens of shells were thrown into the sky in an instant, flying towards their targets......

As the heavy mortar on the far right threw a shell into the air, the heavy mortar on the far left let out another dull sound. A shell, again burst into the sky from the chamber of the first mortar on the far left. This was followed by the second heavy mortar and the third heavy mortar from the left. In an instant, dozens of more shells flew into the distance, and the group of monsters that were rushing towards the outpost camp with great vigor and vigor.

"Report! We can't stop the third wave of! They had already separated a large number of ghost things, and were quickly rushing towards the second wave of ghost things...... Only twenty giant monsters and some small monsters remained......"

Just as the shell of the first 120 mm heavy mortar exploded in the second wave of monsters, the voice of the driver of one of the three Zhijiu who was responsible for monitoring and blocking the third wave of monsters suddenly sounded in Sun Houguang's headphones......
