The gunfire was like a shooting star, crushing into the huge body of the fortress. From the aerial view on the computer, Emerald could even see that the fortress was trembling! Great! She glanced at Patrick, but he was not happy at all. “Sir, all the thirty nuclear bombs have hit the enemy’s fortress.” The technical officer stood up and said loudly with satisfaction. However, Patrick ordered in a low voice, “Stop the shooting, and the left and right sections should both form an umbrella shape to attack; the medium-sized warships retreat to protect the fortresses. All the pilots shall be alert!” At first, Emerald didn’t understand why Patrick ordered to stop the shooting, but after the smoke cleared, she was surprised that the machine space fortress didn’t move and only got several cracks.What is the material of the machine man’s fortress? Ordinary fortresses would lose the power of fighting after being hit by thirty nuclear bombs, but they were still floating in the space stable as if those bombs were nothing to them. No wonder they would give ten minutes to humans. Maybe they thought that humans were not even a threat to them. Emerald stared at the fortress on the computer and suddenly felt that her eyes were blurry. She looked at the screen again and found out that the cracks that looked like waves spread on the surface of the fortress, and many silver gun muzzles stretched out from the cracks! At the same time, hundreds of silver blood hawks flew out of the belly of the machine space fortress. The fortress and the fighters started firing all at once, and the bombs and the bullets had formed a dense net, which was going to cover the human space fortresses and fighters from all directions! The enemy was fighting back!This was an intense battle between offense and defense. Although the humans had been prepared for the war, the sudden arrival of the enemy had limited the war outside the galaxy, and the humans had nowhere to hide. Emerald thought that humans couldn’t even make a war plan because they knew nothing about their enemy. Apparently, the machine man’s power was stronger than the human’s. Their nuclear bombs only made the machine fortress tremble slightly, but the machine man’s bombs had badly injured their space fortresses. Besides, the fighters of the machine were almost twice as fast as their fighters. In this huge gap of firepower, the humans were defeated in the first round of attack after ten minutes. The Cheetahs escaped in disorder, and five space fortresses flew to the back of the galaxy. It seemed that humans couldn’t withstand a single blow, and many technical officers began to worry. Emerald raised her head in fear, and Patrick was still staring at the satellite cloud photograph calmly and made an order every few seconds. She felt relieved and not hopeless anymore. Patrick had been ordering like this for at least twenty minutes, and everyone in the commanding center was extremely busy. When Emerald looked at the satellite cloud photograph, she was astonished. After the first round of retreat, the fighters of machine man had broken their original formation to chase human fighters. Patrick was secretly forming his layout for the past twenty minutes. Now they could see the results clearly. The war field in space was split into dozens of small battlefields. In this condition, the advantages of human fighters appeared. At least five human fighters surrounded every machine fighter. They couldn’t defeat so many human fighters, no matter how fierce they were! It seemed that human fighters had suddenly changed and begun to attack the enemies more fiercely! Emerald was excited when she saw those blood hawks were crushed into pieces. It was Patrick’s strategy to pretend to retreat. But Patrick’s couldn’t make this precise plan in advance because they didn’t know how strong their enemy was. Did he think of these and make the orders all on the spot? Emerald stared at his strong back, but he didn’t look at her. She even believed that the fierce war was all he could think of now. He looked up at the photograph while the signals of enemy fighters disappeared one by one. Although he didn’t smile, Emerald felt extremely proud of him. Captain of the air force had told them proudly and excitedly that they had already destroyed two-thirds of their fighters through the communication channel! Then the rest of the machine fighters took the orders to retreat to the belly of the silver fortress-like tide. When they ran away, over ten fighters were destroyed by humans. All the space fortresses and fighters surrounded the silver fortress again. After the fierce battle, the machine fortress had got many big cracks, though it was much stronger than an ordinary fortress. The two sides kept shooting each other. But humans gained the upper hand when the machine man lost most of their blood hawks. What could you do now? Emerald was happy. She thought the machine civilization had never met such a tough enemy since they destroyed many civilizations. Right at this moment, Patrick suddenly looked up and glanced at Emerald. He didn’t look at her one time during the whole process, but now he stared at her for a while. Then, when the war was going to end, he finally looked at his wife, who had just gotten out of danger. Emerald knew his look. He was telling her that he would protect her as he promised. Emerald felt warm. She put her hands on her stomach and told her son in his heart, “Baby, this is your father. He was a notorious leader of the mercenaries, but now he is the hero of humans.” A year ago, when they knew the coming war in the future, someone had suggested that they should abandon Galaxy Eternity and the mercenaries should all retreat. But after serious consideration, Patrick decided to stay. He said to Emerald, “The war between the mercenaries and the machine man can’t be avoided. Even though we run away from Galaxy Eternity, we will still meet them. Besides, many mercenaries have been married and had children in this galaxy, just like me. They want to fight for this galaxy just like me.”
