The fourteen interstellar cannons were given special care. Although several interstellar cannons had been destroyed before, the captains, who were afraid that they would not be completely destroyed, poured a large amount of firepower onto the interstellar cannons, almost taking out a large pit where the interstellar cannons were located, and then they let go of the entirely non-existent interstellar cannons.

More than ten minutes later, all the military facilities that could be found were devastating. Moreover, due to the existence of the force field, at least one-third of the lasers deviated from the target. No one could tell what the final hit was. Anyway, there were a lot of losses in civil facilities and houses, and the urban area was in a mess.

Ye Fei felt so happy. The last attack on ym174 was two and a half years ago. At that time, in order to stimulate the Atlantis, the intensity of the fleet's attack on the ground was very limited.

This time, there was no more worry about the original one. The unscrupulous raid brought Ye Fei and the officers and soldiers of the entire fleet a sense of revenge.

Jiang Yufei suddenly said with emotion: "The Atlantis' technology is much better than ours. Without the fleet, you will be beaten and not be able to get used to it. No matter how powerful the race is, you cannot do it."

"Haha, are you still pulling it?" Ye Fei smiled and moved the muscles on his face without a smile.

The airborne was about to begin. At this time, he was really not joking. Although he pretended to be relaxed on the surface, he was extremely nervous.

Jiang Yufei tilted his head and said, "I just suddenly felt very touched. In the past, people always said that the truth is within the range of the cannon. Now I finally understand that not only the truth of our human beings is within the range of the cannon, but the truth of the Atlantis is the same."

"All right, I'll discuss these things with you when I have time." Ye Fei interrupted Jiang Yufei's feelings, "Ruan Peng, inform Black Bear that you can start."

"Yes!" Ruan Peng immediately transferred the order to the commando.

The commandos had already gathered in their respective assault ships, and the preparation cabin was in a state of solemnity.

The Black Bear, who received the order, opened the commando's public channel: "All people are careful and board the plane!"

Sixty-seven commandos rushed towards their mecha at the same time and quickly drilled into the mecha. A large combat weapon of four meters high twisted its waist and kicked its legs. It began to warm up before departure.

"Brothers, everyone knows the mission this time, so I won't say much. I just want to tell you one thing. The first one with my surname Ren was airborne and the last one left. The remaining brothers will do it." Black Bear's mobilization did not have any bold words. It was so straightforward that it made people laugh.

But this is the scene, and no commando can laugh, even if he calls all the players a brother - the commando's men and women mixed together. Even if he is a star at the base, he has not forgotten the principle of matching men and women.

However, the army in the war is the place where gender is most vague, there are only comrades, only soldiers, and no men and women.

"Bear Head, everyone knows what kind of person you are. We can trust your character." A warrior said without hesitation.

"Thank you!" The black bear thanked sincerely, and then his tone suddenly changed, "Are you ready?"

"The first team is ready!"

"Hello, the second team!"

"The third team is fine!"

"All four brigades are on standby!

"Set out!" With the Black Bear's order, the four assault ships pulled out of the air in the cabin at the same time. The thick air-tight door slowly opened. The four brigades of flying mechas jumped out of the battleship one by one, forming an oblique flight formation while deforming.

Sixty-seven flying mechas flew directly to YM174. Seeing all this, Ye Fei first silently prayed that the soldiers could return safely, and then loudly ordered: "The whole fleet - fire cover!"

Forty-six warships activated electromagnetic cannons and gravity cannons again, and the rain of fire falling in the sky once again enveloped the sky above YM174. Forty-seven flying mechas led by Black Bear avoided the sky above the city, flew to the left side of the planet, and plunged into the atmosphere.

This position can avoid the cover firepower of one's own side, and the remaining air defense firepower in the city.

The surface of the fighter jet that fell into the atmosphere was covered with a layer of red scorching flames. The thick thermal insulation coating on the surface of the fighter jet evaporated rapidly at high temperatures, taking away a lot of heat and thinning at a speed visible to the naked eye.

Although the flying mecha used an advanced aerodynamic shape when designing, the air resistance still reduced the decline speed rapidly. After entering the stratosphere, the speed of the fighter jet has dropped to Mach 2, and the heat friction with the air is not enough to produce red heat.

Mach means twice the speed of sound. Since the sound speed in the atmosphere is affected by various factors such as air pressure, altitude and temperature, the speed of the aircraft when breaking through the speed of sound at different altitudes and temperatures is also different. Therefore, when calculating the speed of the aircraft, the ground speed is usually not used to calculate, but the Mach number is used to express it.

In other words, the current speed of the flying mecha is not 680 meters per second, which is only 450 and 60 meters per second.

Immediately afterwards, the formation plunged into the force field, and its speed suddenly decreased, and it was becoming more and more slow, just like the shells falling into the force field.

"Black bear, how is the situation?" Ye Fei asked worriedly.

"Fortunately, there is nothing besides the speed impact." The black bear cursed angrily, "Damn it, it doesn't look like a flying atmosphere at all."

"What does that look like?" Ye Fei asked in surprise.

"It's like getting into the paste. Now I feel like I'm a bug stuck to the spider web." The black bear tried to fly 360 degrees and it took five seconds to complete the action that could be completed in just one second. It was simply slowing down the motion.

Flying mechas are like the extension of the commando's body. All external situations can be selectively fed back to the team members through touch. For example, when the high temperature just entered the atmosphere is fed back to the commando's touch, there is only a feeling of heat left, rather than a high temperature that can directly burn people to coke.

"Try Pingfei, collect some data first, which can be used as a reference for taking off later." Ye Fei said calmly.

"Wolf cub, try to level it." Black bear ordered.

"Received!" The thought flashed in the wolf cub's mind, the flaps of the flying mecha deflected, and the fighter immediately began to level it.

Although the fighter planes flying by the commando were flying well, in fact, after learning for a few months, the overall flight skills of the commando were still bad.
