Chapter 49: Locked laboratory building

"The turtle grandson! Do you think this will trap us!"
Liu Feng cursed. He called up 100,000 Irontooth to let them gnaw on the door in front of him. This gate looked like it was made of alloy, and the Irontooth Lv10 ability could definitely shred it.
But the iron tooth worms he was so proud of actually came home with feathers this time, their sharp teeth were all bounced back when they hit the iron gate, and they were completely killed after falling to the ground.
Liu Feng didn’t miss many times, especially when the Irontooth attacked almost victorious. He wanted to call up some more Irontooth to enhance the attack, but found that the function of the system was paralyzed, and the cooling period of the Irontooth was prolonged. Can be used again after five minutes.
Liu Feng didn't dare to talk about this bug, lest Han Bing and the others lose their confidence, but the knife read from his face that something was wrong.
"The material of this door is very special. We have to find a way from other places. Such a hard composite material can't spread all over the building."
The knife ripped off the rags on the surrounding walls. These things like ghost symbols had no practical meaning, but the walls behind them were covered with strange claw marks, which looked like they were scratched by alien animals. .
The claws of this strange beast are very sharp. Every scratch is two to three centimeters deep, eradicating most of the writing on the wall. They seem to be deliberately destroying something, and don't want people to see it later.
"Brother Feng, there is a dashboard behind this!"
Feng Wen yelled and pointed his finger at the value on the dashboard. This is a thermometer. The current temperature has reached 52 degrees, and it continues to rise.
"This value is for us to go to the sauna, Irontooth, come back."
Liu Feng looked up at the rags in the house, summoned the iron tooth insects back, and shredded all the pieces of cloth. Their sharp teeth couldn't chew on the alloy iron door, but they were handy to deal with these rags.
Two minutes later, the original face of this experimental building was revealed. There were a lot of symbols painted on the wall, and some faint blood stains and traces of fighting could be seen. It was hard to imagine what the people who originally were here had experienced.
"There are not only the claw marks of foreign beasts, but also human handprints, but these blood stains are too long, or it may be that the people here became zombies and were killed by foreign beasts."
Xiaodao tried to decipher the words on the wall. She was also born in a laboratory, so she was naturally sensitive to these data. Judging from these data and claw marks, it is likely that some iron beasts have been raised here. This kind of beast is cold-resistant and heat-resistant. It is transformed from cockroaches. It is also the most difficult beast among all the beasts. Used by various laboratories for excavation work.
But this kind of strange beast is the first-generation strange beast, and it is also the lowest. It usually doesn't know how to resist humans. The iron beast here has broken away from its original job and destroyed in the laboratory. It is probably because of some kind of stimulation. There was a second mutation.
"Feng Wen, Feng Wu, look at whether there are controllers and other instruments that display values ​​on the first floor, Han Bing, you take the rest to find an exit, Zerui will definitely leave yourself a way out. This place is absolutely not It will be airtight."
Liu Feng arranged it in an orderly manner. He looked at the height of the floors here. Each floor was at least six or seven meters high. It was indeed a speed-type genetic warrior that could jump up.
"Knife, can you go up to this height?"
Liu Feng turned his gaze to Xiaodao, with questioning in his eyes.
"You look down on me too, but you can't take you with you, you are too heavy."
As soon as Xiaodao's voice fell, she rushed to the second floor like a black shadow. With a light touch on her toes, her body jumped to a higher place. At this speed, it only takes two to three minutes for the eleven floors.
"Liu Feng, there is nothing on it, all floors are empty."
The knife has jumped to the fifth floor, and what you see is still some traces of trying to smear, except for some dust that has accumulated for many years, there is not even a piece of furniture on the ground, and it seems that it has been unoccupied for a long time.
Xiaodao couldn't help being a little disappointed. She wished she could meet a strange beast. Before she died of heat, she could fight happily, and it was good to have a full meal.
"Brother Feng, the controller is not downstairs, but we found some important information."
Feng Wen and Feng Wu held a dusty folder, the information in it had turned yellow, some pages had been gnawed, and there were still huge tooth marks on it, which looked like the work of a strange animal.
Liu Feng glanced around at random and found that it was all written in English. There was no language proficiency in the system upgrade project. Even if he crossed many times, his English proficiency was almost zero.
"What's said above, just say it."
Liu Feng glanced at the thermometer. It was already 65 degrees. If this went on, it would not be a sauna, but a living person.
"Brother Feng, it is said that this laboratory relies on underground magma to maintain energy. At the beginning, the scientists wanted to introduce magma into the underground city. They specially built a huge magma storage pool under this laboratory. We are standing now. On that storage pool, in other words, this place is equivalent to a melting pot."
The sweat on Feng Wen’s face continued, and half of it was shocked by the structure of the laboratory. The data recorded that the magma had problems after being poured into the storage tank. Scientists found that they could not continue to flow downstream as expected, but instead A nuclear reaction formed in the storage pool, which would cause an explosion under a certain pressure.
They made a temporary pressure relief device to delay the explosion, but they couldn't prevent the final result, so they set up a laboratory self-destruct device to reduce the destructive power of the explosion to the minimum.
"You mean this laboratory is indestructible because they want to destroy everything here, including the experimental data."
Liu Feng quickly grasped the point. If those scientists had this idea, there would be no exit from this building.
"Knife, now we are looking for a pressure relief device. As long as we can find that device, we will be temporarily safe."
Liu Feng called upstairs. He didn't notice the knife's whereabouts when he just listened to Feng Wen's words. When he raised his head again, she was gone.
Xiaodao didn't answer, only Liu Feng's echo inside the building.
"Knife, what's wrong with you! What happened!"
Liu Feng felt that something was wrong. The knife probably had something wrong. He called up the system and found that the iron tooth worm's cooling period had passed. He quickly tuned out all the iron tooth worms and made them form layers of repellent armor. , And he himself stood up and rushed to the knife floor as quickly as possible.
