In the underground laboratory of the Tower of Hope, Kate and several others are studying the energy enclosed in the blue crystals, and after studying day and night, those who are under the bright light finally pay off, but they have encountered a new bottleneck, and Kate is very aware that a lot of the information about those substances actually comes from Nick's research on the ashes brought back by Matthew, and the chemical elements in them can produce violent explosions and energy. Kate also knew that the data was still sealed in Area 51, that the samples were still sleeping in the freezer, and that the disk on which the data was stored might have been damaged, but Kate wanted to give it a try anyway.

One morning, while Matthew was running with a sandbag strapped, Kate asked Matthew to gather all his team members at the infantry training camp with a commanding tone, and Matthew did as he saw that Kate's expression was wrong.

After a while, in the shade under the canopy, a few lazy cats crouched on it, and Kate spoke: "For the research and development of the Titan Gun, we have to return to Area 51." "Why?" West was the first to exclaim, followed by Molly: "It's dangerous there!" Then everyone's voices came and went, all of them questioning and denying the action. At this time, Kate had no choice, she was very angry: "This operation is for the course of our war!" If we succeed in developing this technology, what will those alien freaks do? For our planet to be trampled on again! You don't go! I'll go on my own! With that, Kate drove the jeep and returned to the Tower of Hope. Everyone was stunned: "What should I do?" Ben said, "Uh-huh......" Matthew hinted at something about Conner and Ben......

In the evening, Kate picked up the relevant materials, and a tranquilizer bomb launcher, and came to the gate of the aircraft camp, she shot the guard in the neck, the guard fainted, and didn't even have time to press the alarm bell, Kate stole the key and entered the aircraft camp, she took the MP7 submachine gun and a lot of ammunition from the guard, and drove the CH4 helicopter to the 51st District.

At this time, in the sand, a few eyes watched the plane slowly leave with binoculars, "Come on, guys, do something!" Matthew said that it turned out that three insomniac patients, Conner, Ben and Matthew, were following Kate...... All right.

The three of them arrived at the aircraft camp, Conner "friendly" the tranquilizer warhead for the guard, and the three of them left in an Apache helicopter with light machine guns and grenade launchers, they had to be faster than Kate.

Take advantage of the night. Kate came to the ruins of Area 51, oh, a ruin, look, the fragments and stones of the warplanes, the cement slabs, and the wreckage of all kinds of load-bearing walls, broken tiles. "It's sad." Kate whispered, "Apache helicopters aren't covered...... Conner said, and as soon as Kate stepped out of the plane, they came.

"Aha, Kate, it's not good to go it alone." Ben said, "You still have face!" Kate said indignantly. Enough, Kate, stop being childish! That's a big deal! Matthew said solemnly. Let's get down to business. Ben said.

Kate took out a drawing, which was the floor plan of the former 51st District, and this drawing told them to find a ruin mouth and go down, which was Nick's research room - 107N, "Take the weapon and act~" Conner said casually.

Matthew found an entry point and entered Area 51, where the nuclear explosion destroyed the ground facilities, but the safety of the ground was guaranteed, at least not collapsed. "Turn left...... Then turn right...... Go down three units......" Kate said as she pointed her way in the darkness as she said Matthew's flashlight pointed at a sign: 107N.

"Yes, this is it!" Kate called, "The door is locked. Kate said, "Let me do it." Conner kicked the door open violently, and dust covered the room. This is Nick's former lab......" Matthew said with a slight twist of life, after all, Nick had worked with him for many years, "I found the computer!" I'm getting ready to open it! Kate said as she picked up the generator from the box. Ran the computer.

Matthew walked around the long-abandoned hut, Nick's flask, the water in the test tube had long since evaporated, the chemical agents had been spilled, the physical instruments were rusty and broken, and the flower pot was dusty.

"It's ...... This file is required for the date folder...... This isn't ...... This should be the ...... Yes! It's this! Kate suddenly screamed. Got it? Ben asked, "Hmm! Found it, I'm now transferring to disk! Kate said happily, the pale face smiled for the first time, Conner dusted off the dirt on his body, stared at the computer screen, and then, a terrifying rustle came over, very familiar......

"Wow......" The trembling voice of an alien soldier came over, and the scene fell into chaos! The three of them picked up the M60 light machine gun, and in a loud burst of fire, the freak was killed. “kate！ Hurry up! Matthew said with a sigh of relief. Then, more rustling, "Damn! kate！ Hurry up! I'm out there with Ben and Conner! Matthew said as he picked up his weapon and came to the door to guard it.

Gunshots rang out one after another! Terrifying!! Kate sat in the chair with a broken leg and waited anxiously for 100% of the progress bar......

"Fire! !! at 3 o'clock Matthew shouted that the fire of their M60 machine guns would last for a while, "This is not good!" There are more and more of them! Ben said, "Kate! Hurry up! Conner said with some desperation!

As the team resists, an alien soldier breaks through the wall and jumps into Nick's lab. Kate was taken aback! Picking up the MP7 and firing around, everyone heard Kate's exclamation and realized what was happening, "Kate! Hold! Conner threw the dagger as he spoke, hitting the alien soldier in the heart, and Conner fired another shot, killing the freak. Uh......" Kate hated the alien soldier's "blood" and hurried to the computer, only to find that it had been loaded. He put away the device and shouted, "It's time to retreat!" Hearing the news, the two men outside the door retreated to the ladder and opened fire, and the team members climbed up one by one, and behind Matthew, he took out a grenade launcher, shot all the M2 grenades, and climbed up in the fireworks.

"Ahem...... everyone coughed several times. It's dangerous......" said Matthew, "get out of here, the freaks will climb up later." Ben said uneasily that the CH4 helicopter had fallen apart under the shock wave. Oh well, what it's like to be in a gunship. Kate said with a wry smile......

Kate went straight to the Tower of Hope, entered the information, and got a very useful message......
