A few seconds later, the Nakahae slammed into the ground of Europa, and to everyone's surprise, the Nakaha, which was supposed to be shattered in the impact, plunged headlong into the ground, and the nearby ground was covered with cobwebs and cracks like a hammer of glass.

The strong impact distorted the Zhonghai, and several huge cracks appeared in the hull, and there were even small explosions in the ship, but the exposed part of the Zhonghai could still be seen in its original appearance.

Everyone was stunned, what was going on? Could it be that the Zhonghai hit not the ground, but the mud swamp?

The battle continued, and the situation of the remaining transport ships was precarious, and at this time, the nuclear shells finally landed, the strong light flashed on the ground, and more than a dozen air defense bombs were hit one after another, and were wiped off the ground by violent explosions, and the extremely fierce anti-aircraft fire not long ago was instantly emptied, and the crisis of the transport ships was quickly alleviated.

I don't know if it was deterred by the power of the nuclear explosion, and the endless air defense positions finally stopped appearing, and the officer corps headed by Ye Han finally breathed a sigh of relief.

But as soon as this breath came out, Luo Qi suddenly pointed to the screen and shouted: "Look, what's wrong?" ”

Everyone's eyes immediately focused on the position of Luo Qi's finger, and they were stunned to find that he was referring to the wreck of the Zhonghai.

At first, everyone didn't see anything wrong with the Zhonghai, but soon everyone's expressions changed, because the rift near the Zhonghai was expanding and deepening, and the wreckage of the battleship was slowly descending like falling into quicksand.

Everyone was a little dumbfounded, everyone thought of the same possibility, but they all felt that their guess was too unreasonable, and only a few seconds later, the ground near the Zhonghai cracked and sank in a large area, turning into a huge sinkhole with no depth.

The Zhonghai fell with the collapsed earth and rocks, the wreckage of the battleship gradually and quickly crumbled in the fall, the nearby shattered ground with the Zhonghai as the center peeled off layer by layer, and the servants who fell around the Zhonghai also fell with the soil and rocks, and soon disappeared into the depths of the cave, and the whole process collapsed and cracked, just like the special effects in the apocalyptic blockbuster.

What surprised everyone even more was that the sinkhole was very round, and the walls were vertical, like a shaft dug manually.

"What's going on?" Luo Qi's eyes widened in astonishment, "The silos dug by aliens? ”

As he spoke, he activated the biochip's measurement function and found that the shaft was a very round, perfectly circular shaft, and not only at the wellhead, but also inside the shaft.

"I think it's an airport." Lin Yi said.

"Why do you just say it's collapsing?" Ouyang Ping's thoughts were different from others, he was engaged in blasting, and he was more concerned about why the ground suddenly collapsed.

Ye Han guessed: "Maybe it's because of the nuclear explosion." ”

There was no sign of collapse on the ground when the Zhonghai landed, but three nuclear bombs exploded within 10 kilometers of the fall site, and the nearest nuclear explosion site was only about three kilometers away.

Although the yield of nuclear shells is relatively low, it is not difficult to understand that the ground there was first hit by the Zhonghai, and then pried by the earthquakes caused by the nuclear explosion, and finally caused the collapse.

A flash of inspiration flashed in Luo Qi's mind: "Boss, do you think this pit could be an airport dug by aliens?" An unfinished airport. ”

Everyone turned their heads in unison, and everyone's eyes fell on Luo Qi's face.

Ye Han nodded heavily: "It's possible ......"

The diameter of the shaft can fully ensure the free entry and exit of the giant ship, and no one believes that it is not an airport.

"There is a situation!" Lin Yi, who always pays attention to the ground, reminded loudly.

"Prepare for battle-" Ye Han didn't have time to look at the screen at all, and gave the order to prepare for battle as soon as possible.

Everyone's attention immediately turned back to the screen, only to see dozens of underground bunkers in the landing zone open at the same time, and countless light bugs rushed out of the bunkers.

However, none of the light bugs stayed near the exit, and all of them rushed out of cover and ran away.

They are going to lay out air defense positions!

Ye Han was stupid, according to the current situation, it won't take long for thirty or forty air defense positions to appear on the ground, not to mention that he only has three assault ships in his hands, even if the main force of the fleet is still there, it is impossible to destroy so many enemies in a short period of time.

"It's over, it's all over!" Ye Han's gaze was frightened and empty, and he looked at the transport ship on the screen in a daze.

The altitude of the transport ship is about 20 kilometers, and it is impossible to fly back into space at this point, and if it accelerates to land, it will hit the ground because of the excessive speed, and the final result is still that the ship is destroyed and people are killed.

"His grandmother's, but it's okay, get me a nuclear shell to smash!" Ye Han spat out a sentence viciously.

At this time, the ships had already opened fire, but the use of nuclear bombs must be approved by Ye Han, the commander, so all ships used conventional artillery fire, and it was not until Ye Han ordered the use of nuclear bombs that the ships loaded the nuclear shells into the breech.

The turrets of the three assault ships spun rapidly, blasting nuclear shells out of the chambers, and while the first wave of nuclear guns was ejected, the light bugs on more than 30 air defense positions pouted their butts at the same time.

Ye Han, who witnessed all this, seemed to be frozen in his heart.

The speed of the artillery shells was too slow, and he was determined to report to Beidu as soon as the battle was over, asking Beidu to research a nuclear artillery shell that could be fired with electromagnetic cannons.

Isn't it critical mass? If the implosion type doesn't work, use the gun type, no matter how much nuclear material is wasted, it is better than not using it at all! (Note 1)

The light insects on the ground were ready to shoot, there was silence in the bridge of the Yaoshan, and the Shahai, at the bottom of the five transport ships, was ready to be shot down by the enemy.

In an instant, countless thin lights rushed into the sky, and the main screen in the bridge of the Yaoshan suddenly turned white, and then all the screens in the bow direction of the Yaoshan failed, and a strange sound from out of nowhere filled the bridge.

Before everyone came to their senses, the picture on the main screen automatically switched to the management damage system, and everyone was stunned to find that the hull of the front third of the Yaoshan was full of flashing red warnings, and all the weapons and equipment located in the bow and the front of the battleship were not spared.

A thought suddenly popped into Ye Han's mind: The enemy's target was the Yaoshan, not the transport ship!

His whole person was not good, and he shouted on the radio like crazy: "Leave the mountain and cool the mountain, emergency avoidance, emergency avoidance-"

He couldn't see the situation of the Gaoshan and Liangshan, but judging from the aliens' consistent air defense tactics, they should have collectively aimed at the Yaoshan and shot at the Yaoshan, and there was still a chance for the Shanshan and Liangshan.

As expected, the sound of Lishan and Liangshan mixing together immediately came from the radio, and Ye Han decisively activated the separation function of the biochip, separating the chaotic mixed channels into two clear independent channels.

Lishan's answer was: "Lishan is evading, Yaoshan, how is your situation......"

The Liangshan replied: "Liangshan received, Yaoshan, you are losing altitude, repeat, you are losing altitude!" ”
