The staff in the command center watched the final ten seconds of video from the Global 3 type drone.
The footage showed a long black strip and over a dozen light spots on the ground in the farthest distance captured by the Global 3 type drone.
As time progressed, the dozen or so light spots in the air rapidly approached. Then, the Global 3 type drone's feed cut off. It was clear that the Global 3 type drone had been shot down by these energy cannon shells.
Hua Deyun said, "Pause the video at the ninth second."
The staff immediately paused the video at the ninth second.
"Magnify the black strip!"
The staff magnified the black strip.
Upon magnification, it was clearly discernible that the black strip was a convoy. They could also see that some of the hovercars were equipped with machine guns on their roofs.
A staff member exclaimed, "The computer has already calculated the convoy's route."
On the large screen, it was shown that the convoy's direction of travel was towards this very portal.
Hua Deyun stated, "It seems they are coming for us. Prepare to engage!"
Immediately, an alarm blared throughout the base near the portal.
The soldiers in the portal base quickly returned to their combat posts.
Soldiers who were still resting in the underground base's dormitory also immediately got up and rushed out.
The second phase of the underground base had now been completed. In addition to the elevators, a dedicated passage had also been constructed. The soldiers below would use this passage to rush to the surface. After all, relying solely on elevators would take a considerable amount of time.
The soldiers of Longguo quickly reached their respective combat stations.
Hua Deyun believed it was not wise to wait for the hovercar convoy to arrive. They needed to take the initiative.
Thus, the Longguo soldiers, now in combat readiness, moved out according to orders to meet the enemy.
Within just one minute of the order being issued, the first armed vehicle from the military base rolled out. The second and third vehicles followed, quickly merging into a torrent of vehicles. Several Global 3 type drones also flew out from the portal base to scout ahead.
This time, a real-time connected line was used, and multiple drones were dispatched.
The Global 3 type drones soon reached within ten kilometers of the four-armed banished prisoners.
The radar in the convoy immediately detected them.
"Sir, there are two flying objects approaching."
"Ten? They actually sent out ten. Shoot them all down!"
The anti-aircraft weapons in the convoy of four-armed banished prisoners opened fire on the two Global 3 type drones.
Major General Hua Deyun was also issuing corresponding commands.
"Initiate manual control immediately!"
Two technicians took over the operation of the Global 3 type drones.
The two Global 3 type drones evaded the attacks from the convoy of four-armed banished prisoners. The energy cannon shells missed their targets.
The subordinate of the City Lord seemed surprised and said, "The two flying objects in the sky have managed to evade our attacks this time. If only City Lord would deploy that spaceship. But the City Lord's mansion would never deploy that spaceship."
"Sir, what should we do?"
"Add another machine gun to the attack."
At this moment, the two Global 3 type drones overhead had already reached directly above the convoy of four-armed banished prisoners.
The energy cannons on another vehicle in the convoy immediately rose and targeted the Global 3 type drones overhead, opening fire.
With the increased fire from two energy cannons, the two Global 3 type drones in the sky were finally destroyed under the barrage of hundreds of energy cannon shells.
"Hehehe, finally took them down. What's the point even if there's one more flying object?" The subordinate of the City Lord gloated.
At this moment, a four-armed banished prisoner beside him said, looking at the radar feedback, "Sir, there are four unidentified flying objects in the sky."
The subordinate of the City Lord looked but did not see any other flying objects in the sky.
"I don't see them? Where are those flying objects?"
"Sir, those flying objects are at an altitude of ten thousand meters. They cannot be seen with the naked eye."
"What? Ten thousand meters high? These flying objects are really flying high enough. Go and shoot down those aircraft above."
"Yes!"
Several missiles were immediately launched from the convoy of four-armed banished prisoners towards the altitude of ten thousand meters.
Meanwhile, the four Global 3 type drones at an altitude of ten thousand meters had already filmed the battle that had just occurred below and transmitted it to the underground portal base. The tactical analysts in the command center could analyze the firepower of this convoy based on these combat videos.
The missiles quickly reached an altitude of ten thousand meters.
In the underground portal base command center.
"The four-armed missiles have reached an altitude of ten thousand meters and are preparing to attack the Global 3 type drones."
Hua Deyun remained silent, allowing the operators of the Global 3 type drones to make the judgment.
The technician operating the Global 3 type drones directly released four flare rounds.
However, the four flare rounds did not decoy the missiles. The missiles continued to pursue the Global 3 type drones.
This indicated that these missiles were not infrared-guided.
The drones released another batch of chaff to interfere with the radar, and then the four Global 3 type drones separated and flew in different directions.
The missiles caught up with three of the drones and destroyed them. The last drone continued to ascend, and after another thirty seconds, it too was finally destroyed.
The underground portal base command center once again lost visual contact with the convoy.
However, with these videos, much could be analyzed, including the estimated time of arrival for the convoy of four-armed banished prisoners.
In the underground command center, Hua Deyun studied the three-dimensional map for a long time and finally chose a location.
"Set up the formation here to meet them."
The order was immediately relayed to the front-line troops.
The convoy soon arrived at the location designated by Major General Hua Deyun, which was a sand dune.
It was evident that Hua Deyun's intention was to use this dune to construct a defensive line.
The convoy immediately arranged itself according to the battle formation.
Cannons were positioned on the sand dune, and missiles on the vehicles were raised.
In the underground portal base command center.
"The frontline deployment is complete. Requesting latest orders for the frontline."
Major General Hua Deyun said, "Hmm, fire a missile to test that convoy of four-armed banished prisoners! They used missiles, so let's see if our missiles can hit them. The rest will be left to the troops fighting on the front lines."
After Hua Deyun gave the command, two missiles on the front line, which had been raised, expelled flames from their tails and ascended into the sky, flying towards the enemy.
