Captain, your ship has exploded again.

After everyone replenished their ammunition, Zhang Xun led them to the last defensive position on the fourth floor.

Seeing the Chapman robot still attacking, he ordered the remaining two TX robots to lead the charge, leaving Zhao Wanyang with the one in the best condition.

Near the fourth-floor staircase is a large parts calcination furnace, originally used for heating and straightening large parts, but now it can be used to process insect corpses.

TX chopped at the jumping bugs with his hand while clearing away the dead bugs that had accumulated in the tunnel.

Upon reaching the third-floor barrier door, TX took out a large number of offensive grenades and threw them inside. With the explosions, a clearing was created at the entrance.

The Chappie robots immediately stepped out of the door and formed a defensive formation, while the human soldiers served as the second line of defense.

As the defensive formation advanced, Zhang Xun and his group still encountered a small group of thorny snakes.

A large number of Zerglings and Hydralisks are a real problem for units lacking heavy firepower.

Marcus stepped forward, deployed the power armor's missile system, and launched a large number of fragmentation missiles forward.

Looking at the combat map inside his helmet, Zhang Xun said, "We must speed up. We've encountered Zerg Contaminated before. If more Contaminated appear, we won't be able to complete the mission."

“Relax! I believe that reaction missile has eliminated quite a few bugs. The second floor has been completely destroyed. According to intelligence, the bugs initially appeared on the first floor, and I don’t think the damaged Zerg mothership still has that many troops.” Marcus patted Zhang Xun on the shoulder and said.

From the hole created by the reaction missile, a drone was sent directly to the first floor.

Seeing a large number of insects collecting charred insect corpses on the first floor, Zhang Xun realized that what he had encountered earlier must also be a collection team.

Clearly, the high temperatures generated by the explosion of the reaction bombs in the base caused problems with the transmission of pheromones by the Zerg vanguard; otherwise, they would have already charged down by now.

Zhang Xun signaled everyone to enter silent mode and to be careful not to make any noise with their weapons, then cautiously headed to the first basement level.

When they reached the first floor, they discovered that creep had already been laid near the stairs. If they went up now, the enemy would definitely detect them. It seemed that the Zerg had laid a structure on the first basement level while Zhang Xun and Marcus rushed down, which was not a good thing.

Using the in-team voice prompts, we learned that there might be Zerg defensive structures. We called up two soldiers to activate their missiles, intending to use them to probe the situation on the next floor.

As eight missiles were fired near the hole blasted into the ground floor, a large number of insects looked toward the stairwell.

"TX and Chappie, advance and deploy into defensive formation! Prioritize blocking that hole in the ground, and those behind should follow immediately."

A large number of automated weapons were deployed at the stairwell entrance, and the robot troops immediately formed a defensive formation in front of the opening. Human soldiers continued to install defensive turrets, establishing two layers of defense on the first floor.

Seeing the large number of insects charging at the defensive formation, Zhang Xun ordered those holding grappling hooks to pull the insect corpses over and throw them down into the hole.

Seeing the ammunition being consumed rapidly, but the drones sent out still failing to locate the cave, Zhang Xun was getting a little frustrated.

"Zhao Wanyang, you said before that the enemy started their invasion from the first basement level, but we couldn't find the tunnel. Do you know where the first insects were found on the first basement level?"

Looking at the drone video sent by Zhang Xun, Zhao Wanyang analyzed: "Based on the direction of the earliest alarm, it should be near the weapons depot. Pay close attention to the walls. I guess the fungal carpet should be covering the entrance to the hole. The most likely scenario is that the deformed tunnel net covers the underground hole, and it should have a certain ability to deform and camouflage."

MD's habitual thinking can be deadly. In the game, I didn't notice the walls because they were all on the ground, but I didn't expect the Zerg buildings to be on the walls.

Then, near the armory, they found a strange fungal carpet, because it was thicker and vibrated more frequently than elsewhere.

"Found them! But we didn't see any insects. The number of attacks we've suffered is clearly too much to be contained in one layer," Zhang Xun said, looking at the pile of insect corpses that was about to accumulate below the cave entrance.

"Check these coordinates. This used to be a soldiers' rest area. There were over a hundred soldiers here when the Zerg invaded, but we lost contact with them afterwards. The Zerg must have built their nest here," Zhao Wanyang marked the location on the communication map.

The base has long been without power, and the emergency equipment that was working before has been almost completely destroyed. With no one coming to check after all this fighting, there are definitely no survivors.

"Marcus, come help! The rest of you, keep defending."

"Zhao Wanyang, I need the remaining Chapman robots on the fourth floor to come and support us with weapons and supplies. Have the maintenance crew bring the Ingram over, and remember to bring grenade launchers. We'll need them to guard the entrance."

After giving the instructions, Zhang Xun and Marcus began using their lightsabers to cut through the wall, intending to sneak into the rest area from the other side. If they didn't deal with the hatchery there, there would still be a constant stream of insects.

They didn't care about the size of the opening anymore, and melted down a hole just big enough for the two of them to pass through, and then they crawled inside.

When they arrived at the room near the rest area, they saw that the rest area had been completely transformed into a Zerg hatchery, and it was impossible to tell how many hatcheries had been merged together.

All that could be seen was a large number of larvae emerging from the entire wall, and nearly a hundred insect eggs on the ground. Some of them would immediately hatch into springtails, while others might be hydralisks or other insects slowly hatching.

"Do you have something really powerful? I want to blow this place up." Zhang Xun surveyed the hatchery and reached out to Marcus for the item.

Marcus patted himself down, got up, took a reactive missile from the missile launcher on Zhang Xun's back, and handed it to him.

"Holy crap, don't joke around. Using this at this close range would wipe out not only the two of us, but also the entire first floor and the reinforcements coming to our aid." Zhang Xun pushed Marcus away and put the reaction missile back in.

Marcus shrugged and said, "Then there really aren't any left. There aren't many high-powered ammunition for individual soldiers on the fourth floor to begin with, and you used up the last bit on the first floor, so you only have these two left."

The battle was fought in a way that left us with nothing. The fourth floor was still used for repairing mechs in the hangar, and the weapons in the armory on the first floor had long been damaged by the creep.

Zhang Xun said to Marcus, "Go find the reinforcements and get two grenades for the mechs."

"Why don't you go?"

Zhang Xun leaned against the wall and said, "I'm too lazy to move. This hole looks like a dog hole. I don't want to crawl through it."

Marcus gave Zhang Xun an international greeting gesture, then turned back to get the grenade.

After seeing Marcus leave, Zhang Xun began to take out small light shields and various weapons and ammunition from his backpack. Although he didn't have any explosives, he still took out a grenade.

After replacing the lightsaber's nuclear battery, he discovered some unusual eggs in the Zerg hatchery. These eggs appeared larger than the others, and the surrounding creep was converging on them. Zhang Xun guessed that the Zerg were probably planning to hatch a large one in the base.
