"Don't panic, everyone, don't block the entrance of the Chiyou space, go to the Chiyou space ......", Lu Ziming left the conference room, first went to the arsenal, and found a lot of urgently needed weapons and materials inside, as soon as he walked to the entrance of the Chiyou space, he saw that the entrance of the Chiyou space was crowded with panicked people.

Some people saw the Chiyou space built of pure metal for the first time, and their expressions were full of surprise and shock, and they suddenly forgot to command, and gathered around to point at the Chiyou space. There are also some people who have been to Chiyou Space, with mixed feelings, looking at everything around them with depression and sadness, wandering around in a daze and without purpose.

Crying, screaming, cursing, complaining one after another, some people can't find their relatives and friends in the crowd, shouting loudly looking everywhere in the crowd, and the materials on the people are squeezed to the ground, lying on the ground desperately picking up in their arms, more people bow their heads like walking corpses and are silent, as if everything around them has nothing to do with them, the world is full of people, and the warmth and coldness of people are hung on their faces, deducing the tragicomedy of the last days of escape.

"This little brother, help me find my daughter, I was separated from my daughter", a middle-aged woman grabbed Lu Ziming's arm and begged.

Lu Ziming's heart moved, and after a ruthless heart, he still shook off the middle-aged woman's arm, and continued to walk in the crowd in the direction of the entrance of Chiyou Space, "Young man, the direction is wrong, go back quickly, it's very chaotic outside, and there are soldiers guarding you and not letting you out!" A kind old man blocked Lu Ziming's way.

"Old man, I'm going out to kill dark creatures, you can go in quickly!"

The old man said with tears in his eyes: "Young man, kill a few more dark creatures and avenge my wife!"

Lu Ziming walked out of the crowd with difficulty, although there were many soldiers and robots arranged around, the entrance to the Chiyou space was too narrow, and the number of people who could pass through at one time was limited. I also thought about expanding the entrance to Chiyou Space, but now that I am in the underground base, it is impossible to expand the entrance at all, so I can only delay time with the dark creatures as much as possible.

Including Lu Ziming, no one has a bottom in their hearts, I don't know why, it is because of the unknown war that is about to come, or because I saw countless panicked and helpless eyes, my heart is tangled together, as if I have lost something.

As soon as he walked out of the cave, the communicator on Lu Ziming's arm vibrate, and a pale face with bloodshot eyes appeared in the light curtain, and he roared at Lu Ziming with bared teeth: "Oh no, the dark creatures have launched a biochemical attack, and the 5,000 soldiers who haven't had time to retreat are trapped in the position, let's find a way!"

Before Lu Ziming could react, he saw black balls appear in the sky in the background of the light curtain, covering the sky and the sun and falling around the picture, Lu Ziming was stunned for a moment, and then reacted, "Explosive insects!"

This is the second time Lu Ziming has seen an explosive insect, the first time is with Lao He and a few people on the ground position, I didn't know what it was at the time, it was round and black with a metallic luster, I thought it was a rock or something, but I didn't expect it to be a mutant insect with strong acid. A large amount of strong acid is stored in the explosion bug, and as the strong acid in the blast wave of the explosion splashes everywhere, as long as it is stained a little, it can melt the steel plate into a hole, and it is not difficult to imagine what will happen if this strong acid is completely splashed on the body, and Xiao Xia is the living victim.

When the explosive insect was first discovered, it was known that this kind of biological and chemical weapon had a huge impact on the base, so the base also sent people to go deep into the hinterland of dark creatures to check, but there was not even a trace of the explosive worm.

This time, the explosive insects that appeared in the sky were not one, but a piece of black pressure, and there were at least a few hundred of them, which fell on the ground and exploded quickly. The strong acid splashed into the air fell like raindrops, and the corrosive sound of "swish" could be clearly heard on the building, making people's scalp numb and the hairs on their bodies standing upside down. Even if the soldiers hiding in the building will not be corroded by the strong acid for a while, but the acid rain formed by a large number of explosive insects makes the surroundings "muddy", even if the shoes kick on the soil with strong acid, the soles of the shoes will quickly corrode, and then enter the soles of the soldiers' shoes, the sharp stinging sensation brought by the strong acid makes the soldiers panic, and the soldiers who fell in the strong acid in the panic keep wailing, and the wailing sound is like a terrifying gust of wind in hell blowing across the battlefield.

Lu Ziming felt soaked in ice water that had not melted for thousands of years, his body shivered involuntarily, and his mind was in chaos, like the tumbling magma in the earth's crust, and his heart was pounding uncontrollably.

"This ......!"

"What to do! What to do! There are still 5,000 soldiers trapped on the position......", God knows how many explosive insects there are in the dark creatures, and you don't need to think about it to know that the number will definitely not be small, but the dark creatures have never used explosive insects to attack the ground position, this kind of biological and chemical weapon is still powerful, and after the number reaches a certain level, the entire ground position is soaked in strong acid, and even the attack is saved.

"That's not right!" Lu Ziming's eyes lit up, if the explosive insect was easy to use, why did the dark creatures only use it now. It's definitely not a matter of quantity, but the strong acid blow in the body of the explosive insect is a two-way street, harmful to humans and equally harmful to dark creatures.

"Iron Brigade Commander, did the dark creatures stop attacking at the same time as they launched the explosive worms!"

When Tie Xiong heard this, he immediately reacted and said: "Yes, the strong acid of the explosive worm also stopped the attack of the dark creatures, but our soldiers can't retreat, we can't abandon the besieged soldiers, we must rescue them."

"Iron Brigade Commander, don't worry, I think there must be a way, strong acid is mainly corrosive to flesh and metal, wood and cement have a certain corrosion resistance, you can find some wooden boards to try first", Lu Ziming couldn't think of any good way for a while, what he could think of for the time being was the knowledge in chemistry class, and he could only expect that the speed of the dark creatures launching explosive insects would not be as fast as the speed of the soldiers retreating.

"I can only try it first! I hope it's still too late," Tetsuo cut off the call.

It is impossible for the dark creatures to know the turmoil in the base in advance, and they can only hope that the dark creatures are not ready for a full-scale attack, and it depends on who moves faster in a hurry.

More and more information was transmitted from the front line to Lu Ziming's communicator, and a hideous dark creature appeared in the picture, some of which he had seen before, and some of which he had never seen, but Lu Ziming knew that these were the hidden strengths of dark creatures, and now they were all taken out at once, not that the dark creatures had reached the point of exhausting their skills, but that it was the best proof that the dark creatures launched a comprehensive general attack.
