Chapter 3

A Deadly Virus

Over the next two days, Ulysses and Xana fit in perfectly at Kadic Academy. Things went by rather fast, Ulysses picking up where he left off in his education and Xana was a fast learner herself as her theoretical knowledge became precise, and things got even better when the Lyoko Warriors had science with Franz Hopper as it would make it easier for them to tell him if HADES has launched an attack. On the 2nd day at Kadic, however, Yumi discovered strange things happening around her, along with the others, so they went to talk to Ulysses about it. Yumi asked first. "Ulysses, can we ask you something?" she asked.

"Yes, what is it?" asked Ulysses.

"I wanted to ask you about some slight side-effects from Wakusei," said Yumi, " Yesterday after school, when I was going to do my homework, as I reached for my pencil, it floated into my hand like my telekinesis power was active."

"And when I was late for class earlier today," said Ulrich, "I found myself running through the halls at about 60 miles per hour without running into anyone!"

"That's almost the same with me," said Odd, "Except it happened during gym. I found myself climbing the wall with ease like a cat climbing a tree!"

"It happened to me as well," said Aelita, "When Jeremie and I were missing a vital piece to one of our robots, I simply thought about it and it appeared before us."

Ulysses thought for a moment and said simply, "Ah, it's nothing. It's just a programmed side-effect from Wakusei called 'Bleeding'."

"'Bleeding'?" asked Odd.

"Yeah," said Ulysses, "It's a little something I programmed in so that people who have entered Wakusei for the first time can keep the abilities from Wakusei in the real world too. We're basically super heroes now."

"Cool!" said Odd.

At that moment, Xana walked in. She was covered in mosquito bites. "Sorry to come in like this," she said, "But word of advice, don't step outside for the next few days without bug spray."

Ulysses knew instantly what she meant. Mosquito season started that day and it was terrible. Everyone had to keep itch cream and bug spray with them wherever they went because the mosquito swarms were everywhere. That aside, it was also a coincidence being that they were researching parasitic insects and life forms in science class with Franz Hopper as their new science teacher.

Things were interesting for the time being, until Ulysses felt something like an electrical surge through his brain, and somehow he knew HADES had launched an attack. "Uh, sir?" said Ulysses, "May I talk to you for a minute?"

"Yes Ulysses," said Franz, "What is it?"

Franz lowered his ear to listen to Ulysses. "HADES has launched an attack!" he whispered, "I don't know how I know, but I can feel it. We have to go!"

Franz nodded. "I see," he said. At that moment the bell rang, and when everyone except the gang left the room, Ulysses explained to the others what he had just experienced and they were off.

The Lyoko Warriors left the school for the nearest passage to the warehouse, being bitten by a bunch of mosquitoes before they went through the door. "You guys OK?" asked Ulysses.

"Aside from all these mosquito bites, we're fine," said Jeremie.

"I think HADES' plan has to do with the mosquitoes," said Xana.

"I think so too," said Ulysses.

When they got to the warehouse, they had to run inside because the entrance was overrun with mosquito swarms. After they got into the lab, Ulysses started up the new super-scan. It located the activated obelisk immediately.

"The obelisk is in the jungle sector," said Ulysses.

"Well, let's get this over with," said Ulrich as he held his forhead, "I'm starting to get a headache here."

"Yeah, me too, oddly enough," said Ulysses as he held his forehead, "Wait a minute." Ulysses bit his thumb and let a drop of blood fall on the analyzer. He started up a program and found an abnormality in the blood composition. "Just as I thought!" exclaimed Ulysses, "HADES possessed and mutated these mosquitoes so that they would kill us with their venom! The disease in them is not West-Nile or Malaria, but a mutated form of the Hantavirus!"

"The Hantavirus?!"exclaimed Jeremie.

"Yes, a very deadly disease at that," said Ulysses, "But it's been mutated. The symptoms we exhibit will manifest within a short time and they will kill us if we don't shut down the obelisk."

"How long do we have?" asked Xana.

"Maybe a few minutes," said Ulysses, "We've already started experiencing headaches. According to the analysis, the next symptoms we will exhibit are high fever, severe dizziness, internal bleeding, acute shock, and finally death."

"Then there's no time to lose!" said Jeremie, "Get to the synchronizers and I'll launch the procedure!"

Everyone entered the room and got on the synchronizers. Xana looked excited to be doing this for the first time. "Jeremie," said Ulysses, "If we appear to be in any danger, use the emergency sync program and you will come in to help us out. Don't worry about your body, it will still operate while you're in Wakusei."

"OK," said Jeremie, "Here we go! Transfer! Scan! Synchronize!" The jungle sector looked almost like Lyoko's forest except the branches were the only platforms, there was no visible floor beneath them. Xana was admiring her Wakusei outfit, a black dress with metal plating and her weapon was a sword with a giant blade.

"Alright let's go, guys!" said Ulysses, "We've only got so much time before the symptoms go drastic!"

They didn't waste time, they were off. The obelisk was further than Ulysses had expected, so Xana summoned Mantas to get them there faster. They got to the obelisk in a few minutes, only to find that it was guarded by a couple three-headed dog monsters, two Skorpiens, and a giant monster with a single eye and a huge club. "Damn it!" muttered Ulysses, "HADES has spent some time creating powerful defenses for this one obelisk. Three Cerberus, two Skorpiens, and the Polifemos."

"How are we going to get past those monsters?" asked Xana.

"Try to create some matching monsters that will help us out," said Ulysses, but he suddenly started feeling dizzy, "Oh, God. The fever and dizziness symptoms are kicking in!"

Everyone else was suffering the same symptoms, including Xana who was losing control of her Manta. "Jeremie, how much time do we have left?" asked Xana.

"Only two minutes before the acute shock, resulting in us going unconscious!" said Jeremie, "You've got to find a way to shut down that obelisk before it happens!"

"Jeremie, open the Retrotempus program," said Ulysses, "Enter the time coordinates for yesterday at 7:00am. The program will send us back in time when I deactivate the obelisk!"

Jeremie did so as the group prepared for attack. Xana managed to create the Kollosus to face the Polifemos, Odd used his close-quarters-combat tactics and laser targeting to get rid of the Cerberus, and Ulrich, Yumi, Aelita, and Ulysses managed to kill the Skorpiens. "Th-that's the last of them," coughed Ulysses, but when he looked down at the hand he coughed into, he saw tiny droplets of blood, "I've got to hurry! We're almost out of time!" He immediately jumped into the gravity lift and into the obelisk. Jeremie had already gone unconscious and everyone outside the obelisk was also dropping due to the disease. Ulysses held on for as long as he could so that he could enter Code: WAKUSEI into the obelisk. "O-obelisk shut..down," said Ulysses as he collapsed on the floor in the obelisk. Luckily the Retrotempus program activated and they were sent back in time to the previous day at 7:00am.

Everyone was brought back alright, but Jeremie was rather curious as to how Ulysses had developed a program similar to the Return to the Past program. Ulysses explained to him that he created a device that harnesses tachyon radiation and when activated, the Retrotempus will release the tachyon radiation and send the whole universe back in time according to the coded Earth time. It took a little while for Jeremie to understand the concept of the machine, but he got it in time.

Yes, they did have to do everything over again, but it was worth it for Ulysses as it gave him more time to work on the linking program, which was almost finished as it required only a few more adjustments.

Man, HADES must have really meant business when he tried to kill our heroes, but at least Ulysses managed to act fast, and now he's working on the linking program to connect Lyoko to Wakusei. Will it be successful? Find out later on...
