The Shadow Fortress, which had been quiet for some time, sounded the alarm again, and dazzling light beams penetrated the night and focused in the direction of the main entrance.
A chariot roared out of the smoke and rushed towards the fortress at full speed. There were two biting beasts hanging on the body of the chariot. The fortress guard tower immediately erupted with gunfire, and a hail of bullets struck the main battle tank. Of course, these large-caliber machine gun bullets cannot penetrate the armor of the tank, but they can kill the strange beasts hanging on it.
More chariots appeared and rushed towards the fortress.
The fortress gate slowly opened, allowing only one chariot to pass through.
At the end of the chariot unit are several combat mechas. They shoot while moving, constantly blocking the large swarm of beasts behind them.
There was a sudden roar of artillery in the fortress, and all the heavy artillery was firing, forming an intercepting barrage less than fifty meters behind the mecha. A heavy cannon at the highest point in the center brewed for a long time, and then sprayed out a ball of ion plasma shining with a faint blue light.
The plasma ball fell into the tide of beasts, instantly vaporizing all the beasts within the explosive range. The war beast next to the core area was also covered with electric sparks and fell to the ground. However, the lethality on the periphery is much worse, and many war beasts are still running despite the electric fire. On Planet 4, what they are least afraid of is electricity and acid.
The fire interception of the fortress still blocked the beast tide at the periphery. Under the cover of the fortress' firepower, the remaining troops were able to withdraw to the fortress. The thousands of chasing beasts still refused to give up and continued to attack the city, and then were torn apart by the defensive firepower of the fortress.
In the central square of the fortress, Joseph stopped the mecha and jumped out. William also got off the mecha, but when he landed, his body shook and he almost fell.
Professor Hermann came in a hurry and was shocked and asked: "How could this happen?"
"We were attacked halfway," William said.
"But the ones chasing you are just a few C-class beasts. How could the losses be so huge?"
Joseph smiled bitterly and said, "Remember how we killed the beasts that gathered when the Cambrian was just installed a few days ago?"
"certainly."
"That's what they do."
"What?" Herman couldn't believe his ears.
William said: "Okay, let's treat the wounded first and renovate the equipment. In addition, send a message to the Legion's outer space base. We need a large number of anti-aircraft weapons, especially missile defense."
"Is it really a missile?"
"Biological missile."
Herman turned pale and left in a hurry. William and Joseph looked at each other with solemn expressions on their faces.
At Base No. 2, Chu Jungui held a huge ammunition box and inserted it into the anti-aircraft gun tower. This batch of sniper rifle-based anti-aircraft gun towers has a low rate of fire and does not require high ammunition preparation. Therefore, Chu Jungui specially developed a large ammunition box with a capacity of 50 rounds for use in the gun tower. Using ammunition boxes can significantly increase the speed of the gun turret's aiming movement and expand the firing range.
After loading the ammunition box, Chu Jungui loaded a bullet and stretched his body.
Not far from the base, two tractors were moving. Seen from the top of the base, they have turned into several small light groups. On the night of Planet 4, every ray of light means a living companion and a warm presence.
At this moment, the distance between the two parties exceeded the communication range, but Chu Jungui knew that it was Lin Xi and what was on the tractor behind her.
Just after crossing 1,000 meters, Lin Xi stopped and led several soldiers to start setting up the fusion explosive device.
Chu Jungui shook his head helplessly. Although the yield of these fusion bombs was only a few tons, there would still be considerable aftermath at a distance of a kilometer. Moreover, it is difficult to calculate the exact equivalent of this kind of transformation, and there will be a considerable error. It may be 2 tons, or it may be seven or eight tons.
He picked up the ammunition box and was walking towards the next gun tower when suddenly he saw something abnormal out of the corner of his eye!
Chu Jungui turned his head and saw a group of black spots in the distant sky approaching quickly!
There was no need for the helmet display to adjust the field of view, Chu Jungui automatically focused and saw clearly the appearance of the incoming object. He immediately activated the base alarm and shouted on the communication channel: "All attention, prepare to defend against missiles! Missile position: 737, 412."
missile?
Many soldiers didn't understand what was going on. How could there be missiles in this damn place? But some reacted quickly and blurted out: "The Shadow Fortress must be attacking again!"
All the soldiers suddenly understood and rushed to their posts at full speed.
Lin Xi outside the fortress also discovered the enemy's attack. She didn't panic and programmed the tractor to run automatically. The tractor turned on all its lights and headed into the distance at full speed. Lin Xi then rushed to the base with a few soldiers and turned off all the lights at the same time.
Chu Jungui took over control of all anti-aircraft gun towers and some of the automatic gun towers facing this direction.
There were 60 incoming missiles, and they were clearly visible at this moment. Seeing their constantly expanding and contracting bodies, even the test subjects were shocked. Are all these missiles alive?
No matter what comes, Chu Jungui will not let them get close to the base. He quickly locked onto the target, and as soon as the missile group entered the range, all the anti-aircraft gun towers opened fire at the same time.
The head of the missile flying at the front suddenly exploded, and it immediately lost its target and flew around in the air. More than a dozen other missiles were also hit, some exploded in the air, and some crashed to the ground.
"17 hits, which is a bit low." The test subject was very dissatisfied with the results.
At this time, the disadvantage of the slow firing rate of the anti-aircraft gun tower appeared. After three seconds of reloading, the missile group had flown from 5,000 meters to less than 2,000 meters.
The interception effect increased in the second round, and all 20 rounds were successful. However, there is still half of the missile group.
The two satellite bases have opened fire, and the soldiers controlled the remote-controlled gun towers to intercept. However, the missile flies extremely fast, and the target is small. Moreover, it does not advance at a constant speed, but is propelled by jets as it expands and contracts. Therefore, its speed alternates between fast and slow. Almost all the intercepting firepower missed, and only Rose was shot down twice in a row. Got two.
The automatic gun tower controlled by Chu Jungui finally opened fire, hitting most of the targets in an instant. Chu Jungui deliberately placed the targets within a thousand meters to increase the hit rate, and at the same time captured the moment before each target's body was about to expand to its maximum size, which was also the time when they were flying at their slowest. With Chu Jungui's archery skills, he would not miss this opportunity.
However, after several missiles were hit, they suddenly exploded in the air. The shock wave pushed other surrounding missiles aside, and also knocked out the gun tower controlled by Chu Jungui on the ground.
"Oops!" Even the test subject did not expect such a change and immediately controlled the gun tower to move and intercept. But how can the speed of the gun tower's rotation and adjustment catch up with the missile? Moreover, the movement of these missiles in the shock wave became irregular. Chu Jungui successively fired follow-up shots, but all missed.
A total of four missiles broke through the interceptor fire net and flew over the base!
