Liu Yuxin had been waiting anxiously for more than ten minutes. His weak team did not dare to go further forward, so as not to trigger the elite Zerg who could fight against the warships to intercept. However, the pursuit troops from the main Zerg base behind him were pressing step by step and could appear in their sight at any time.

"We have to find a place that is easy to defend. If the opponent only needs a long-range volley, we will be finished."

Although Liu Dongfang is a scout, he is also a regular military class graduate. He quickly saw the shortcomings of the terrain here.

"We can't go too far. We don't know where the cordon of the front-line stronghold of the insect swarm is. If we get too close, it may lead to the elite troops in the stronghold."

Liu Yuxin considered it and agreed with his opinion. The space for this tunnel to move is too small, and there is no such thing as a cover, and it cannot withstand the impact of the Zerg at all.

Several people walked forward a few hundred meters and finally found a slightly wider place. Liu Dongfa stopped.

"Let's just build defenses now"

Liu Yuxin smiled bitterly

"It's too late, they have arrived! Now we can only guard the tunnel entrance, hoping to last until the reinforcements arrive."

Liu Yuxin's radar showed that a red spot appeared 3 kilometers away from them, filling the entire passage.

Liu Dongfa asked in surprise when he looked at his empty radar screen

"It's already here? But it's not displayed on my radar? There's no reason why enemies of that size cannot be detected, right?"

"The swarm of insects can control their own life characteristics well and have natural resistance to our human life detection radar. Even my detection equipment with very strong power on the King Kong can only find them within a range of about three kilometers."

“Three kilometers?”

Liu Dongfa pondered for a moment

"According to the Zerg's action power just now, we have a maximum of 2 to 3 minutes of buffering time! Zhao Changshun, remove the supplies on your back first, and everyone equips me all the weapons that can be equipped with, and place the box at the entrance of the hole as a cover."

Liu Dongfa is preparing to fight back here!

Several people opened the box and hung the weapons inside on themselves desperately. What are the ammunition of electromagnetic rifles, plasma grenades, backup energy batteries, and take as much as they can.

"Shen Fugui and Zhao Changsheng were guarding both sides of the tunnel entrance and relying on the cover of the wall to attack. My mecha's armor was thicker and could be used as a moving firepower point. Brother Liu was responsible for cleaning our leaking fish."

None of the people present was better than Liu Yuxin's grasp of the battlefield. Seeing that everyone was ready, he took over the command without hesitation.

Shortly after the battle position was assigned, the ground began to tremble slightly. Under the searchlight of the mecha, pangolin-like alien species in the tunnel showed their figures.

After discovering his pursuit target, the alien species directly launched a charge and suddenly accelerated its speed.

Without any orders, Shen Fugui and Zhao Changsheng stretched their upper body out of the wall and used the electromagnetic rifle in their hands to freely shoot the aliens in the tunnel.

"Swish swish swish swish"

"Swish swish swish swish swish swish"

...

The hard and dense metal striker penetrated one alien body after another, carried the juice and internal organs in the front row, and flew into the back row until his kinetic energy was exhausted.

In just a few seconds, dozens of alien species were removed from their ability to move and fell to the ground by the deadly ammunition, and then they were trampled into meat paste by the same species.

This small casualties did not cause any waves in the alien population. In the blink of an eye, the most exotic species at the forefront were only about 300 meters away from them.

Liu Yuxin did not expect that a few electromagnetic rifles could block the charge of the insect swarm. It was estimated that the insect swarm had reached the best shooting range, so he rushed out and used the laser Gatlin, which was constantly spinning the barrel, to pull up a red light belt that was about to die when touched.

"Swoosh, swosh..."

The continuous high-energy beam cuts through the air and melts into one big hole after another on the alien body. The bullet holes on some alien bodies are even densely connected into one piece, and the bodies lacking support are broken into several pieces and sprinkled on the ground. Although the high-energy laser cannot fly across the alien flesh like ballistic weapons, its silent cutting has forced the alien offensive down, and the front line is pushed back 800 meters away. The alien never dares to emerge directly from the corner again, and Liu Yuxin and the others also stopped shooting in time.

For a moment, the whole world became quiet again, leaving only a few seriously injured Zergs in the tunnel, dying and crying. The Zerg commander also realized that the tactics of the military sea in front of heavy weapons did not work, and did not drive his subordinates to come and die. The two sides temporarily became stalemate.

In this rare moment of peace, Liu Yuxin and the others seized the time to replenish themselves with ammunition. They knew very well that as a complete ethnic group, the attack method would never be only this level. After a brief calm, there would definitely be another attack like a storm.

"Changshun, do you think we can go back alive?"

Shen Fugui lined up the magazines on the ground and quietly asked Zhao Changshun on a private chat channel.

"How do I know? You have to ask the other person what the other person thinks of "

Zhao Changshun carefully stretched out his head and looked into the tunnel

"No wonder those old seniors always warn us that they would not say that they would do whatever they would do when they go back this time. Why can't I hold back? Alas, it seems that Xiaohua can't wait for me..."

Shen Fugui's tone was a little depressed. There were only a few people on his side, and reinforcements were nowhere to be seen. No matter how you look at it, the chances of successfully getting out are very slim.

"Be calm, they're coming."

Liu Dongfa saw a group of red dots on the radar passing through the stacks of alien species from the rear, and interrupted their conversation in a deep voice. The new alien species coming from the rear should be the key to dealing with their heavy weapons, and they must not be taken lightly!

Figures more than 4 meters long emerged from the corner. Their bodies were dark, with thick armor on their backs of 4 meters long and 2 meters wide. The round faces of about two meters in diameter were covered with gray-white bones, and the two eye sockets were deeply trapped in the bone armor. Four pairs of thick legs spreading all over the cracks were evenly arranged on both sides of the abdomen, supporting the body weighing more than ten tons.

Seeing them appear Liu Yuxin's pupils shrink

"Do we have any other heavy weapons?"

Judging from those exoskeletons with heavy alien species, the power of their own Gatlins is completely unable to cause effective damage to them.

Liu Dongfa naturally understood what Liu Yuxin meant and pointed to the plasma grenade spread on the ground.

"Those grenades may be the only thing that can fight them."

Liu Yuxin looked at the few dozens of grenades

"Once we're done dumping, we'll retreat! Don't hesitate!"

At this time, the 10 new alien species had been lined up in two rows and slowly approaching them, followed by a long list of ordinary pursuit troops.

They can actually cooperate tactically!

When they approached 500 meters, Liu Yuxin's Gatlin roared again, and the long beam of light was connected into a straight red line under Liu Yuxin's control and continued to burn at the same point. A few seconds later, a alien armor was finally burned through by a high-energy laser. The laser that penetrated the body instantly roasted its body into coke. The walking alien twitched and fell to the ground, and a gap was immediately opened in the first row.

Before Liu Dongfa and others could breathe a sigh of relief, a alien species in the back row ran up to fill the gap.

"Damn" x3 (Liu Yuxin doesn't like to speak rough words)

In just a few seconds, the insect swarm had advanced more than 100 meters. Liu Yuxin estimated that even her gun skills could not penetrate the formation before they approached him, and sent them a gesture to Liu Dong.

"When they get closer to 200 meters, they will throw grenades!"

The time came in a flash. Three plasma grenades with removed safety were thrown out and flew towards the swarm. A second later, three more were. After hitting the alien species, the six grenades exploded with balls of high-temperature plasma. The armor of the alien species, which was stuck to the plasma, melted at a speed visible to the naked eye. Soon the alien species roared so hard that it turned around and ran back, knocked down several companions and fell to the ground.

After a round of plasma attack, the fragile ordinary alien species had been exposed. At a distance of 200 meters, even soldiers who had been slightly trained could accurately hit large targets like alien species, not to mention several elite-trained scouts and the talented Liu Yuxin? The metal striker fired by high-energy lasers and electromagnetic rifles immediately spread throughout every section of the tunnel. In just a dozen seconds, Liu Dongfa and others shot 3**.

"Click~"

Shen Fugui replaced his electromagnetic rifle with a new magazine.

This round of counterattack smashed the alien offensive plan and suppressed them to the corner of the tunnel again.

This time they really calmed down for a while until another batch of alien species arrived.

"After two tests, they have figured out our strength. Now we must be ready to run away at any time!"

Although he had not been in contact with this group of alien species for a long time, Liu Yuxin was deeply awe of the random adaptation of the alien commander. Judging from its several responses, its intelligence is very high and can reasonably use the resources in his hands to give the other party strong pressure. In fact, its tactical arrangement is no worse than that of ordinary battlefield commanders. If an opponent with sufficient resources cannot defeat them after a few tests, it will not be able to match his previous performance.

This time, the lead was still two thick armored aliens as shield walls, followed by a square array of dog-headed pangolins, and then another section of shield walls, followed by a square array. Gradually, the tunnel was filled with alien species, and the rear array of alien species could no longer be observed through the gaps.

"Guga"

"Guga"

"Guga Guga"

...

A strange sound rang out from the back of the insect swarm

Liu Yuxin's face changed and shouted

"Be careful about cover! It's a ranged attack!"

His body also rushed toward the side of the wall, without stopping after landing, and rolled again to avoid the front of the tunnel entrance.

The green juice that emitted a sour smell passed over the head of the alien species, followed Liu Yuxin's landing points, and fell to the ground after being shot in the air, making a sizzling corrosive sound.
