"YAHHHHHH!" Sissi screamed, fleeing for her life. A massive blast hit the ground where she had been just seconds before, leaving a crater several meters across. All eyes were fixed on the green disk floating through the air, raining laser fire down to the ground. No one noticed Jeremie, Yumi, Aelita, Odd, and Ulrich running out of the dormitory building, towards the main academic building.
"So Einstein! You got a plan?" Shouted Odd over the din.
"As a matter of fact, yes. Just follow me. I'll explain when we get there."
They ran up the stairs to the roof, where they had a good vantage point of the rest of the school. Jeremie went over to the tower that held the school's antenna. They hadn't been up there since the time Xana took control of the satellite through the kids' cell phones.
Looking over the various wires leading from the dish to the fuse box at the base of the tower, Jeremie plugged in his laptop and began typing.
"Jeremie, what are you doing?" Asked Ulrich.
"Well, this antenna is made to accept and give out radio waves. But if I can increase the frequency of waves it gives out, eventually they won't be radio waves any more, and if I can increase it enough, I can make it give out a concentrated ray of visible light."
"In English, please."
"Well, I'm going to make it shoot a laser beam at the UFO. I need you guys to get up there and move the dish into position so that its aiming at the ship."
"Got it covered." Said Yumi. She, Odd, Ulrich, and Aelita climbed the tower and, with great difficulty, pushed the dish so that it was aiming at the saucer. Jeremie pushed the enter key. At first, it looked like nothing was happening, but then the little stick in the center started to glow white hot. A few seconds later, a beam of white light erupted from the antenna, slamming into the ship at the speed, of, well, light.
The beam went out the other side of the ship, and a moment later the ship exploded in a large fireball. The debris flashed and disappeared before they hit the ground. The students, hearing the explosion, turned around to see that their pursuer had been blown up, and after a moment of stunned silence, started cheering. But they had not seen what exactly, made the UFO explode.
----------
Aelita looked out at the school grounds. The paths and fields were pockmarked with blasts, and the gym had a huge hole in the roof. The dish had not been able to handle the energy it had emitted, and had melted.
"Looks like if we ever get out of this, we need to return to the past." She said.
"Well, yeah, I mean, even before that we needed to. Everyone would be questioning later just where we were." Said Ulrich.
"Oh yeah." She said thoughtfully. "So why are we staying up here?"
"Its a good lookout point to see if Xana is sending any more spaceships. But how we're going to fight them without that dish?"
"I don't really know." Said Jeremie. "I suppose I'll think of something. But in the meantime, I have to continue programming the program that will allow me to materialize the vehicles from here." He was already hard at work.
Down on the school grounds, the teachers, still dazed from the attack, were making a half-hearted effort to put things back in order. Many of the students were standing around or staring up at the sky, as if expecting more flying saucers to come flying out of the void at any time.
Unfortunately, their fears were not unfounded. Deep in Sector 5, Xana had watched the whole thing from his chamber.
"Hmm.. So they were able to defeat my spaceship. Well, they will not fare so well against two." He said to himself. "Lieutenant!" He shouted.
A Blok scuttled into the room and made a stiff bow.
"Board the ships. And prepare to make a landing when you get there." He said. The Blok bowed again and scuttled out of the room. Outside, twenty more Bloks and five Krabes were waiting. They followed the Lieutenant to a large chamber that bordered the outer sphere of Sector 5, where several more of the recently constructed green saucers were waiting. They entered through hatches in the side of each ship, and when they were all boarded, the two saucers took off through a wide door in the wall that led to the celestial dome outside. They shot out of Lyoko, heading for the small floating island that was the school.
-----------------
Yumi was the first one to see them.
"Look! Over there!" She shouted. The green specks had appeared from the direction of Lyoko, and were moving rapidly towards them. The kids down on the ground noticed them too, and the panic started all over again as they ran for shelter.
"No! Not indoors, I tell you! Not indoors!" Shouted Mr. Delmas. Nobody listened to him.
The first of the flying saucers flew over the roof they were standing on, and stopped there. A large hatch surrounded by the smaller hatches opened up, and five of the Bloks jumped down, making the roof shake slightly.
"Uh oh." Said Jeremie.
"No sweat." Said Odd. "We're experts at this sort of thing." He took aim, but then noticed that there was nothing on his hands.
"Oops." He said, a little embarrassed and a little afraid.
They had left their weapons back in their rooms.
