There was a sound of surprise in the conference room, through the picture transmitted by the nano insects that sneaked into the dark creatures excavation channel, you can clearly see that the passage is filled with dark creatures of all sizes, all kinds, and strange dark creatures, most of the dark creatures are seen for the first time, and the scalp is numb and cold sweat flows down the back of the back.

"Whether you believe it or not, judging from what has been observed so far, the number of dark creatures attacking the underground base has exceeded 300,000, among which there are very few low-level dark creatures, most of them are third- to fifth-order dark creatures, needless to say more, you also know what is different between this time and before!"

The dark creatures below the third order are all cannon fodder, and only the dark creatures above the third order are the main force of the attack, and judging from the picture transmitted back from the passage, the dark creatures above the third order account for more than sixty percent, and even the rare sixth-order dark creatures seem ordinary, and even a few seventh-order dark creatures have been seen, and their huge bodies are desperately squeezing around in the narrow passage.

If you don't understand these pictures when you see them, these people are really "wise and foolish", in the past, when dark creatures attacked underground bases, most of them were cannon fodder below the third order, although there were many of them, but the overall combat effectiveness was not strong, and it was easy to repel.

It's completely different now, both in quantity and quality, and if that's not a general attack, then what is a real dark creature general attack, just thinking about it makes people shudder.

Dashan frowned and said, "Brother Lu, what now?"

Lu Ziming waved his hand again to bring up the picture of the underground base and said: "The general attack time chosen by the dark creatures is very good, if we are given a few more hours, the chaos in the base can be alleviated, and the follow-up work will be carried out one after another, but now we have no time......."

The light curtain appeared on the picture of the ground position of the base, and from the air overlooking the attack position of the entire dark creatures, there were also dark creatures like a sea tide that were gathering in a tense and orderly manner, and the next moment they would launch an attack on the ground positions of the base.

I don't know why, Lu Ziming had a strange feeling, I don't know if it's his own delusion, it seems that the dark creatures are not ready for a general attack. Countless dark creatures scurried back and forth around the position, as if they were nervously mobilizing the "army" to arrange their troops, and in the panic, there were high-level dark creatures who overturned a low-level dark creature to the ground, and the scene was extremely chaotic and disorderly.

But no matter how you look at it, the dark creatures are preparing for the attack, although it is difficult to speculate on the main attack side of the dark creatures, but now that the base has just gone through a turmoil, it is the weakest and most in need of recuperation, and the attack of the dark creatures at this time is definitely a fatal blow for the base.

"As you have seen, the dark creatures are not only as simple as invading the underground base, whether it is a frontal attack or a sneak attack on the underground base, we can't resist now, so we have to retreat to the Chiyou space, and the sooner we evacuate before the dark creatures attack, the better. ”

Lao He frowned tightly and said: "Brother Lu, not to mention that there are forty or fifty thousand people in the underground base, even the ground troops also have one or twenty thousand people, and it is impossible to evacuate the Chiyou space in such a short period of time."

Luo Lan continued: "That's right, according to the speed of the dark creatures' excavation, the fastest time for the underground base to invade is only ten minutes, and the time for the ground dark creatures to launch an attack will not exceed half an hour, which is probably too late to even notify the people in the base!"

Lu Ziming's face was covered with gloom and said: "That's true, if you want to evacuate everyone in the base now to the Chiyou space, it will take more than 6 hours even if you put it in normal times, but now we don't have time at all, so my plan is to fight and withdraw at the same time, give up some ground positions and some unimportant places, try to drag down the dark creatures, and use the complex structure of the underground base to fight a tunnel battle with even more dark creatures. Tug-of-war and sniper warfare, only in this way can the people in the base be evacuated to the Chiyou space to the greatest extent."

Tie Xiong opened his mouth and said, "I call you Brother Lu, don't see outside!"

"Please!"

"Okay!" Tie Xiong was not pretentious: "Now there are more than 10,000 soldiers on the ground position of the base, plus seven or eight thousand soldiers in the base, they are under the jurisdiction of different troops, this is one of the reasons, in addition, there are about forty or fifty thousand ordinary people in the base, some of them are everywhere, I don't know how Brother Lu moved these people to the Chiyou space." In the end, with the current military strength of the base, we can delay the dark creatures for a long time, I'm afraid that without a day, we can't evacuate to the Chiyou space at all, I don't know what Brother Lu has thought about?"

Lu Ziming raised his eyebrows and said: "What Brigade Commander Tie said is not wrong, we have no time, and we lack organizational ability, this is the biggest problem we are facing now." But the problem is not difficult, as long as there is a solution to everything we can think of, I will start with four points......".

Lu Ziming's gaze swept over everyone's faces, and finally stayed on Li Juan's face: "Needless to say, there is only one way for us to go now, if anyone thinks there is another way, they can stand up and refute it now!"

"Okay! Since you have nothing to say, let me talk about my own plan," Lu Ziming said with a serious expression: "First, the Iron Brigade Commander contacted the ground troops and abandoned the ground fortifications, and all the ground combat troops retreated to the entrance of the first floor, established fortifications at the entrance of the first floor, and strictly guarded against the evacuation plan for at least 6 hours. Second, Li Juan and Luo Lan contacted the defenders inside the base to build fortifications at the junction of the second and third floors, and evacuated the ordinary people inside the base to the second underground layer. Third, I personally led the Yiming team and the vassal escort team to defend the second layer to buy time for the base to retreat. Finally, the others, led by Xiangxiang, moved to the Chiyou space in an orderly and rapid manner under the leadership of Xiangxiang, no matter who obstructed me, it must be suppressed by thunderous means, and if there is no opinion, it will be executed immediately."

Li Juan didn't want to listen to Lu Ziming's command, so she stood up and said, "There is a problem, in the plan you mentioned, the ultimate goal is to retreat to the Chiyou space, and finally close the entrance to the Chiyou space. The problem is, we've all entered the Chiyou space and let the dark creatures occupy the entire base, have you ever wondered how we're going to get out of here in the future?"

"That's a good question!" Lu Ziming stared at Li Juan's fair face lightly, and said with a smile: "When this base was built, we didn't consider the attack from the underground at all, so this base has a fatal flaw, and after the dark creatures capture the base, they may not retreat quickly, so how we leave has become everyone's biggest concern!"
