"Something's happening!" The programmer immediately shouted over the radio without even thinking about it, reminding everyone that this was not an accidental touch, but a real alarm.
Several programmers determined the direction of the sound source as quickly as possible. They just determined that the sound source was on the left side of the Dead Sea. A similar sound source was also discovered on the other side in the direction of the Nanhai and triggered an alarm.
It's not an accident, this is definitely not an accident, but another counterattack by the enemy!
The alarm bells in Ye Han's heart rang loudly, and he shouted at the top of his voice: "Attention, all units, be on guard against death -"
His attitude was unprecedentedly solemn. Aliens are good at digging holes. It is not surprising to dig tunnels to get closer to the base. However, the previous wave was based on ground attacks, and this wave was changed to underground attacks. This shows that the enemy is very clear about the advantages and disadvantages between us and the enemy.
So we chose to dig underground, probably to withstand shelling!
No, not just shelling, but also air strikes from battleships. As long as you hide underground, you can avoid human heavy weapons, thus greatly reducing the casualties of the noble army!
The plan was not as fast as the change, and Ye Han made a quick decision in his mind: "One regiment, two regiments, the troops will be delayed for the time being!"
"I understand!"
"The second group understands!"
"Monitoring team, report the latest situation at any time!"
"yes!"
After issuing several orders in succession, Ye Han let out a long breath, glanced at the satellite image, and suddenly felt an indescribable irritation in his heart.
The enemy is coming too fast!
It's not that Ye Han hasn't thought about the current situation, but it's precisely because he thought about it carefully that he became more aware of the hidden worries behind the attack.
If you think about it carefully, it is not difficult to find that when the monitoring network heard the abnormality underground, the enemy's position was not far from the encirclement.
It’s true that aliens are good at digging, but if they want to dig right under the eyes of the defenders, they can’t dig just casually. This means that the enemy’s digging operation has definitely not just begun. With Ye Han’s
I guess, the excavation started before the last round of attack was over.
If there was no need to dig tunnels, wouldn't the noble army's attack have started long ago?
The allied forces of humans and resistance organizations have successfully landed. It is strange that the noble army is not in a hurry. It is not strange to launch continuous and continuous attacks on the base area.
However, the premise of all this is that the coalition forces are strictly guarded and do not take a step out of the base area. The landing coalition forces have a chokehold on the noble army, and they cannot sleep until the coalition aliens are eliminated.
But what is the current situation? As soon as the coalition forces landed, the main force of the servant army broke through the siege of the noble army and took the initiative; it was the noble army that surrounded them, and most of them were wiped out by the defending coalition forces; it was that all the underground bunkers located inside the base area were blown up
; It’s the base group’s troops that have invaded Ganymede!
To put it more bluntly, the coalition forces have already established a foothold on the surface of Ganymede, but have shown no intention of continuing to develop underground. At this time, the Noble Army's first target should be Albert's landing force, even if the Noble Army
There is no shortage of men, so there is no need to draw troops from the vicinity of the base area. We should first deal with the main force of the servant army who are advancing bravely.
The noble army has indeed been trying to block the main force of the servant army, but the results have been limited. No matter how you look at it, the top priority is to concentrate more superior forces and defeat the main force of the servant army in one fell swoop.
But the noble army’s choice was to attack the base area!
So what is the intention of the noble army? Cut off the retreat of the main force of the servant army? Cut off the support of the base area to the servant army? Or do they have other ulterior motives?
Ye Han had a headache. He couldn't accurately judge the enemy's intentions without finding a reason. Now all he could do was to block it with soldiers and cover it with water and soil.
So after thinking carefully, Ye Han issued a new order again: "Regiment 1 and Regiment 2, I am No. 1. I order you to organize your manpower immediately and place nuclear mines outside the encirclement. Pay attention to keeping a distance and execute it."
Although Ye Han's order did not explain the reason, Xiao Yuan and Bian Ge realized that Ye Han was targeting the enemies digging underground. They agreed in unison and immediately arranged for manpower to execute the order.
Soon, more than a dozen teams operating in squad units broke out of the encirclement and deployed nuclear mines about 1,300 meters away from the encirclement, with a sufficient safe distance between any two nuclear mines.
As long as these mines are detonated, the shock caused by the explosion will not destroy the enemy's underground transportation network, but at least it will cause some trouble for the enemy and delay the follow-up troops.
Just as the various teams were busy, Ye Han suddenly received a report from the monitoring team: "No. 1, an abnormality was found outside the Dead Sea. The sound source is 20 meters deep and 40 meters away. The depth is rising and the speed is very fast!"
Before Ye Han could speak, the monitoring team reported again: "On the outside of the Nanhai, the sound source is 18 meters deep and 75 meters away. It is digging upwards!"
"Inside the Shahai, the depth is fourteen meters, the distance is fifty-five meters, parallel excavation..."
Ye Han was a little dazed. Why had there been so many abnormal sound sources suddenly when there had been no movement before?
How did he know that this was actually the result of the monitoring team completing the optimized combination of monitoring programs to improve monitoring efficiency.
The monitoring team's continuous reports made Ye Han realize that something was wrong, and he quickly called up the floor plan of the base area. The monitoring team had marked the locations and excavation directions of all sound sources on the map.
He immediately noticed that the distance between all sound sources and the battleship was within 100 meters, the depth was within 20 meters, and the direction of all sound sources was pointing towards the battleship!
Ye Han immediately became alert: "Attention, all units, prepare to fight!"
The satellite picture could only show the ground, and the enemy moved underground. Ye Han could no longer control the battle situation as before, but this picture showed the underground situation in front of Ye Han, giving him a new basis for judging the enemy's situation.
At this time, each team that went out had completed the mine laying task. If the sound source was not too close to the battleship, he would have immediately detonated several nuclear mines to give the enemy some color.
Just after the order was issued, the monitoring team reported again: "Report, the sound source No. 4 in the direction of Shahai has disappeared!"
Ye Han suddenly had an idea: "Where did the sound source disappear?"
"Thirty meters outside the Shahai, with a depth of six to eight meters."
Just as Ye Han's eyes fell on the position where the sound source disappeared, the voice of the monitoring team appeared again: "Report, the sound No. 2 in the direction of the Dead Sea disappeared, the distance is 26 meters, and the depth is six to eight meters!"
"Report, Nanhai..."
"Report, Red Sea..."
All the reports were similar, the sound source disappeared, the distance was within thirty meters, and the depth was six to eight meters!
Ye Han almost heard the alarm in his mind, and he immediately shouted on the radio: "Everyone, pay attention..."
As soon as he shouted these words, more than a dozen earthbags suddenly bulged out from the outside of the Shuhai. There were also earthbags bulging in other directions, seven or eight at the front and rear, and about ten more on the inside. The noble army had not yet emerged from the ground.
