Five hours have passed since the deployment of nuclear warheads on the underground front, and Cao Chuan has no way of knowing how many nuclear warheads have been successfully deployed, but judging from the movements of several squads, the number of them is at least more than five.

This means that five nuclear warheads with a yield of 500 million are lurking deep underground, and when the set time arrives, they will turn the underground world upside down, forming a strong earthquake of at least 8 or more around the surrounding area, completely destroying the unknown construction achievements so far.

However, at this time, Cao Chuan saw that the situation on the ground front had changed drastically again, with so many spaceships and unmanned units carrying out intensive strikes on the unknown, the unknown who had originally gathered at the target location were almost dead and wounded, and even the results of their hard work so far, dozens of spire types, and a few nest types have been turned into ruins.

Such an achievement can be said to be the greatest result after they came into contact with the unknown, and how much damage will be caused to the enemy by annihilating 10,000 unknown people at one time?

Cao Chuan was not complacent, they did destroy the unknown ground lair, don't forget, there are still seven or eight strongholds on the huge Pluto, and there will be more in the underground world, and this achievement alone doesn't mean anything at all.

Moreover, as the unknown number of destinations falls to the bottom, the number of unknowns around them is still increasing, and from time to time you can see the edge of the digital battlefield, one by one quickly flashing red dots, representing waves of unknown tides that are pouring towards the main battlefield from all directions.

There were already several locations, and the soldiers in charge of defense had to face an unknown 10 times their number, and in this gap, even with unmanned units working together, they still saw the defense line being torn apart little by little.

In the face of this anxious, even defeated, situation, the commanders present did not feel that they could not save face, after all, they are not facing the unknown human beings, they like to use tactics against them, they are not losing strategy, the situation has changed so far, the only reason is that the absolute power of the unknown is too strong.

"It's horrible... It is impossible to imagine how devastating an unknown landing on Earth will be! Major Zhang Lang from the Night Rabbit Country sighed with emotion, glad that the East Galaxy Company was in the way, and their country had a little support for manpower and material resources, and would not be directly threatened by the unknown.

Lieutenant Colonel Angolof of the Polar Bear Country looked at the digital battlefield with a black face, and through the real-time soldier status information presented on it, it was easy to find out how many of the Polar Bear State soldiers on display were still alive and how many were dead.

The numbers told him that the situation was very bad, at least 300 Polar Bear soldiers were completely killed, and another 200, even if the East Galaxy Company promised generous medical conditions, they would undergo limb regeneration and organ rebuilding surgery, he could imagine how much suffering these soldiers would endure.

"Damn unknown... Why is it so terrible..."He is also glad that the Polar Bear Country, which has a vast land area of 17 million square kilometers, is not occupied by the unknown for the time being, otherwise they would be such an embarrassing scene.

Unbeknownst to them, the scale of the battle on the underground front was small, and the level of danger was far greater than that on the ground, and the soldiers who had completed the second phase of physical enhancement often had to fight the terrifying Tentacle Type and Tentacle Type II without heavy fire support.

They just knew that the situation was getting worse, and they surrounded Xiao Guanhai, "Minister Xiao, you see the current situation, the unknown outpouring speed is intensifying, we must find a way to dispatch reserve forces in advance, otherwise the soldiers on the battlefield may be at least half of the battle losses." ”

The 50% battle loss ratio is unimaginable in modern times, and since World War II, few modern countries have reached this level of warfare, including several countries that promised the East Galaxy Company, but they never thought that the enemy would be so strong before entering the war, and the combat effectiveness of each individual is similar to that of a heavily armed special forces, not to mention the difference in numbers.

It's just that now, since you have come here, if you quit halfway, no country can afford to lose this face, and the East Galaxy Company has shamelessly chosen to broadcast live every day, so if your own people hear the news that "the soldiers of the Polar Bear Country are retreating from Pluto for fear of death", when they go back, they will definitely be drowned in saliva.

Xiao Guanhai didn't rush to reply, he solemnly observed the situation on the battlefield, the soldiers of the East Galaxy Company who participated in the war also sacrificed a lot, the costly soul recovery device has not yet been popularized, they can only find a way to rescue those who are missing arms and legs, he will only be more anxious than others.

He clearly knew that if he used the reserve forces now, if he didn't know what forces were hiding, they would not be able to react at that time.

He waited patiently, and at this time, he saw that the underground battlefield, the squads of the underground front under the full responsibility of the East Galaxy Company had completed the deployment of more than 60% of the nuclear bombs, turning into 7 flashing identification points, and at this time, another batch of unknown reinforcements with a number of 2000 joined the battlefield.

He slowly raised his head and informed the other commanders in multi-Chinese, "Everyone, it's okay, thank you for your support, our underground front deployment has been basically completed, you can consider a retreat plan..." Xiao Guanhai pointed to the map, the commanders of the various forces were relieved, exchanged opinions with each other, and soon believed that they could retreat in two directions, the first direction was the southeast direction, that is, the direction of the second base; The other direction is northwest, which allows you to quickly enter the open and uncharted safe wilderness, so as to gain respite.

After Xiao Guanhai expressed his support, the commanders issued a retreat order to their subordinates through the digital battlefield.

But let's not forget that there are still a staggering number of enemies on the battlefield, and if all the soldiers just retreat, why not let them run rampant on the surface world? And they retreated, who will cover the underground troops who also need to retreat after the deployment of nuclear bombs?

Xiao Guanhai came to Cao Chuan.

"Report, Mr. Advisor, our strategic intent has been achieved, and it is unknown that the line of defense that is still being tightened to encircle us is still being intensified, so considering the current progress of the underground front, I think it is time to prepare to use the forces of the back."

"Is the time almost there?" Cao Chuan nodded, and he agreed with Xiao Guanhai's decision, "Then, Minister Xiao, please hurry up and rescue the disabled soldiers, avoid abandoning them, and don't let them suffer from the subsequent nuclear explosion." ”

After Cao Chuan finished speaking, he whispered a few words: "Nana, our soldiers are almost unbearable, the unknown is still pouring out, there are still 8 hours before the nuclear explosion, I will trouble you below." ”

"I heard the master." Nana hid behind her back and said, "Then it should be my time to appear, and in addition, I ask White Lotus and Joan of Arc to help and support." ”

Immediately afterwards, the soldiers who were still retreating on the battlefield were horrified to see that the unmanned attack aircraft that had been under their control rose back into the air, the land heavy firepower units that did not carry any members turned around, and from the second base, another 8,000 unmanned attack aircraft and more unmanned units poured out of the nest and rushed to the rift area.

"Ha, what are you still in a daze! Forgot our battle plan? Second Lieutenant Kashimasuke patted his subordinate on the shoulder, as an officer, he knew what was going to happen below, "It's Miss Nana's performance below, we just need to enjoy it." ”
