After entering the mysterious hotel, Veget and Midorikawa Seina went out alone to investigate the hotel, rescued a man named Kenji Ong Moth in the hall, and found a more bizarre cave, after everyone caught up, Mikoto Misaka, Nobita, Takeshi Tsukada, Hideki Izuki and Koo Bone River 5 people began to investigate the cave, Mikoto finally asked some news from the mouth of a survivor, but the man was suddenly killed, Mikoto and Nobita immediately chased after the murderer.

"Da Da ......" The two people kept chasing the man, but the man ran faster and faster, and after a while, there was no shadow.

"Damn...... That guy is familiar with the cave......" Mai Trin said.

"Sister Mai Trin, don't talk yet, I hear something!" Nobita said.

So Mikoto Misaka also began to listen slowly, and sure enough, she heard some small sounds.

"That's right, the operation was successful, and a lot of combat data has been collected, evidence? You think too much, it's impossible to leave it! The government explained that it was just a nuclear power plant leak, and everything was done. A voice was speaking in the distance, so Mai Trin and Nobita walked over slowly, and when they noticed who a man was talking to, they slowly walked over to a huge rock behind the man and began eavesdropping.

"Don't worry, it's just a little accident, and then we just need to get out of here. The man said.

"Da Da!!" Suddenly, a small rock fell and caught the man's attention.

"Huh?" the man turned suddenly.

"Suffered...... It's been discovered!!" Mai Trin said in a cold sweat.

"Who's hiding there, you're well hidden, but unfortunately, you've been exposed!" the man said.

"Damn...... It's too careless...... Mikoto found her shadow exposed, and was seen by the man, "Nobita, you hide here and don't come out!!" Mai Korin whispered and walked out slowly.

"Girl, why in such a place?" the man asked. "Roar, aren't you the girl you just now, you can actually chase here, but I didn't expect a girl to be able to live in this kind of hell for so long. ”

"Who are you, and were you the one who killed the man?" asked Mai Trin.

"So what?" the man asked rhetorically.

"What the hell is your purpose?" asked Mai Trin.

"Hmph, why do I tell you, all I can tell you is that you're going to die here!" the man pulled out his gun and pulled the trigger.

"Smack!!" Mikoto Misaka directly picked up the flying bullet with her hand.

"Do you think this kind of thing will work for me?" Mikoto asked coldly.

"Monster...... Catch the bullet with your bare hands......" the man said secretly.

"It looks like you won't be able to tell you anything if you don't suffer something. "Mikoto's body has begun to burst out of electricity.

"Woo-woo!!" Something suddenly screamed, and a huge black shadow fell.

"This ...... What is this guy?" the man said in surprise.

"What a big spider...... Is this guy also a product of that virus......" Mai Trin said in a cold sweat.

"Whew!!" The spider's mouth suddenly spat out white silk, and the white silk instantly entangled the man, and the gun in the man's hand fell to the ground.

"This ...... This guy ...... Is it a monster!!Is it a mutation of a virus?" the man said in a cold sweat.

"Quack!!" the spider screamed twice, then quickly crawled towards the man, opened its mouth with saliva, and bit off the man's upper body.

"Ahh......h Ahh......hh Ahh......hh Ahh......h

"What a disgusting guy...... I can only fight!!" Mai Trito said.

"Quack!?" After the spider finished eating the man, it found Mikoto Misaka, and without saying a word, it spewed out white silk again.

"Cut!" Mai Trito dodged the attack with a flip back, "Whew!!" Suddenly a large amount of green stuff landed on Mai Trito's head.

"What a smell!!It doesn't feel good!!" Mai Trin dodged the green stuff at full speed with the electric current, which instantly corroded the ground when it hit it.

"It's so corrosive...... Spider Mutation...... I'm afraid that there is an unimaginable amount of venom, so you can't just attack with your fists, and the space here is too small, and if you use the ultimate electromagnetic cannon casually, you might ruin the entire cave...... Sure enough, I still have to use that one here......" Mai Qin instantly liberated the power of level6, and the two dragons on her body began to entangle.

"Raijin spear!!" Mikoto Misaka's current slowly converged on her right hand, and a Thor spear slowly appeared.

"Whew!!" the big spider spat out a large amount of silk thread, and the silk thread rushed towards Mikoto Misaka.

"Hah!!" Mikoto Misaka slashed the threads with a single shot, and raised Thor's spear with one hand, throwing it at the big spider.

"Zizi!!" The powerful Thor spear instantly pierced the big spider, and the big spider slowly lay on the ground, trembling constantly.

"Final Blow!!Raijin·destroy!!" Thor's spear began to burst with a powerful electric current, exploding in an instant, blasting the giant spider in half.

"Huh......" Mai Koto lifted level 6, and the two dragons slowly disappeared.

"Nobita, Sister Mai Trito, are you okay?" Fat Tiger and the others ran over.

"Ah, as you can see, the two of us have nothing to do. Mai Trin said with a smile.

"We've made a major discovery, and we've already given up our shirts and gone back to call everyone. Fat Tiger said.

"What discovery?" Nobita asked.

"I'll talk about that when Vegett and the others come. The husband said.

"Huh!" As soon as the young man finished speaking, Vegette used teleportation to bring everyone over.

"It's so fast!!" Mikoto and the others said in surprise.

So Fat Tiger and the others told others what they had discovered.

"There's an elevator on the other side?" asked Veget.

"That's right!!!It's suspicious that there's an elevator in a place like this, and it's likely to be the entrance to that research institute. Izuki said.

"Tsk...... I can't go back now, so I might have to go to the institute. Saint Nai said.

"Well, hurry up! This cavern looks like it's about to collapse, and it looks like I've been pushing a little too hard. Mai Trin said.

Without saying a word, everyone ran in the other direction, and soon saw an elevator, and everyone immediately took the elevator, and the elevator began to slowly descend.

"Veget, how are you resting?" asked Mai Trin.

"I said I'm not tired, I'm just a little hungry, and I'm ready to move after eating something. Vegit said.

"But is it really good? We feel like we're killing ourselves when we casually break into this kind of lab. Nobita said.

"I can't say for sure, but this might be an opportunity. Izuki said. "To build such a facility in such a place, we must have considered an escape route that would be used in times of emergency, and if it goes well, maybe all the roads in this research institute will lead to safety. ”

"Will it go this way?" Shizuka asked.

"Now that's all I can believe. Fat Tiger said.

"Everyone, are you ready, the door is about to open. Kenji said.

"Squeak......" Vegett slowly drew his sword and stood in front of the elevator door, while the others raised their guns.

"Whew!" the door slowly opened, and everyone immediately raised their attention to the highest level, but nothing attacked.

"It seems like it's okay...... Come in!!" Vegette said.

"This ...... No matter how you look at it, it's like a research institute......" Mikoto said.

"What that uncle said is true, this is indeed a research institute, and I am afraid it is directly related to the study of that virus. Nobita said.

"Woooooooo

"Tsk...... Someone is coming to greet you so soon, everyone get ready to fight!!" Vegit said.

"Wait, there's something in the back!!" Mai Trin said.

"Whew!!" I saw a large black shadow behind this zombie suddenly sprawl up, "Smack!!" Blood splattered, and the researcher's head was instantly chopped off by the claws of the black shadow.

"Green ...... Gorilla-like monsters!!" Nobita said.

"Phew!!" Fat Tiger didn't say a word, and when he raised his shotgun, several bullets hit the gorilla's body, splashing a lot of blood, and the gorilla screamed and pounced on everyone.

"What a hard skin, let's aim the gun at that guy!!" Fat Tiger said, and for a while the bullets and bullets were beating the gorilla wildly.

"Woooo

"Woooo

"Cut...... Is there more than one...... Hurry up and get into this room. Izuki said.

"Whew!!" one of them ran in the direction of the Izuki shirt.

"Kill the Dragon Sword!!" Vegett slashed down with a sword, cutting the orangutan in two.

"Zizizi!!" The other one was also attacked by Mikoto Misaka's electricity, and it fell to the ground, shivering constantly.

"Everyone, hurry up and come here!!" came out of the wooden shirt suddenly shouted, and everyone immediately ran to the room where the people were and found that it was a screening room.

"Screening room?" Veget asked.

"That's right, everyone, hurry up and take a look at this!!" Izuki put the contents of the computer into the projector, and the projector showed the contents of the computer to the wall.

"Ambrera Confidential Research Materials...... Interesting...... I'm going to see what's inside, get out of the wood, and start playing!" Vegett said.

"Click!" out of the wooden shirt pressed the enter key, and a picture of a zombie dog and the introduction was displayed in front of everyone's eyes.

"This ...... This guy is ...... The zombie dog you met in the back mountain!!" Nobita said.

"I'll take a look at the introduction...... This zombie dog is codenamed MA-39, this zombie dog is a guide dog as a body, and was born after the T virus, although due to the influence of the T virus, the skin rotted in a large area during the experiment, but successfully improved his speed, jumping power, durability, and ferocity, fully equipped with the conditions as a weapon, it can be said to be B.O.W. Vegett said lightly.

"T-virus...... I'm afraid that's the name of this virus...... B.O.W, whose full name is Bio· Organic· Weapon, which means organic biological weapon, this institute ...... Sure enough, there's a problem!" Vegett said in a cold sweat.

"So, let's go on!" Izuki pressed enter again.

"This guy is the guy who attacked me at the hotel!!" Kenji said.

"This one too...... This one too...... The hunter we just knocked down...... Chameleon...... And that big spider, all of them are B.O.W. from this institute, and this institute is a B.O.W research institute at all!!" Veget said in a cold sweat.

"This ...... This kind of thing has always been in the city......" said the little man tremblingly.

That is to say...... So far, all of the things that have caused this are ...... This Ambrera is a dry ......," Yasuo said lightly.

"We don't know what happened, but our town was destroyed because of Ambrera's research. Saint Nai said.

"Hey...... Is that the end of the slide here?" asked Mai Trin.

"I didn't ...... There's another one. Izuki said.

"Is it ......" Mai Trin slowly pressed the enter key, and the last picture, codenamed T-002, with the full name TYRANT, appeared in front of everyone.

"This ...... This guy is ......," the crowd said in a cold sweat.
