(Today's second update is released. Friends who have passed by are asking for collection and recommendation. Your support is my greatest motivation)

With the lesson of the trap before, everyone was careful about the next period of the journey. Fortunately, they did not encounter any danger. The doors of the living area were opened, boxes, cabinets and drawers were searched, but the few people found nothing. As Penis said, except for the information hidden by the two hidden bodies, it seemed that someone deliberately hid all the information, could not find anything related to the institute, or even anything related to daily life.

Unfortunately, she left the residential area. Vivian was still walking in the front, looking disgusted. Panis followed her closely, but she was a little distracted.

"What's wrong with Panis, is there any problem?" Katherine, who was walking in the end, discovered Panis's loss of composure.

"I was just thinking about the trap we encountered before. I always felt that the trap was meaningless and even marked and reminded me in front of the door. I couldn't figure out why this is. Is it delaying our progress? Or is it reminding us to be careful of the danger at all times?"

"Don't think about it for now, Panis." Vivian suddenly stopped: "There is a door here."

"I saw it." Panis didn't understand what Vivian meant: "I've seen many doors along the way."

"There shouldn't be a door here," Vivian explained: "This is a corridor from the residential area to the R&D area. It is already a relatively important place and there shouldn't be an irrelevant room."

"You can tell if you open it and look," said Catherine.

"I'll try." Panis walked to the door and checked for a moment, shook his head: "This is a magic lock, and it can't be opened in ordinary ways. Vivian, try it."

Vivian put his right hand on the door, closed his eyes and remained silent for a few minutes: "It's very troublesome, very troublesome. It's indeed a magic lock. Only with accurate magic attributes and accurate magic oscillation frequency oscillation magic lock can it be opened. If the continuous input is wrong, the security defense system of the Mage Tower will be activated. Oh, no, activate the security defense system of the institute. I don't think anyone wants to challenge this system?"

"The defense measures at this gate are so strict, it must be an important place." Catherine said: "Is there a way to crack it?"

"I'm trying." Vivian's eyes didn't turn and answered casually: "The magic defense system of the gate is connected to the magic supply of the entire institute, so the energy is almost infinite. The idea of ​​using out the magic power of this defense will not work. If you directly destroy the gate, not only will the security system of the mage tower be activated, but the counterattack measures of the gate itself can exert the power of the legendary peak under the supply of all the energy of the institute, and we can't live any of us."

"Why not break through the wall without going through the door?" Pannis put his hands on his chest and looked at Vivian patiently: "Is it possible?"

Vivian shook her head: "I have considered it, but I just checked it and the walls are also within the scope of the security system. I guess the room inside is covered with the security system, up, down, left, left, front and back, and six sides, and it won't work."

Vivian put her big backpack on the ground beside her, constantly taking out some strange equipment from her backpack, knocking and sticking to different positions on the door, and then she was disappointed to take it back and for another one. She jumped up and down with the change of position, and fine beads of sweat oozed out of her forehead.

"It seems like I have some idea." Vivian was stunned for a moment, dazed intently. After coming to his senses, he looked joyful on his face: "Let's look, I look, I look, I hope it will work, it will definitely work, you are a genius, there must be a way. By the way, sister, lift me up, I want to look at the top. Forget it, I will do it myself." As he said that, he muttered a few words softly, reached out to the ground, and a rope appeared on the ground out of thin air, wrapped around her waist and held her to the top of the corridor.

"Ha, the magic channel is indeed here. Well, no, it doesn't work here. You have to move forward, and a little further forward, oh." With Vivian's thoughts, the activation rope fixed to the ground was constantly tilted and extended, and the angle to the ground continued to decrease, until the inclination was too large, and the soft rope could no longer support her body, and threw her firmly to the ground.

"I deserve it." Seeing Vivian rubbing her forehead with tears in her eyes, Catherine went over to help her up angry and funny: "I always make such a rash and don't worry about falling to death. I've told you many times, think about the consequences before doing things, but you never listen. Think about it, this time it's not high, what if it's higher, what if it's on the edge of a cliff? Do you fall like this too? You yourself..."

"Sister, I was wrong." Vivian clasped his hands together and raised it over his head: "Give me aside. I just had some idea not to get rid of it for me, please."

Catherine sighed helplessly: "Forget it, don't care about you, just throw you to death."

"Stop making trouble." Vivian smirked and took Catherine's hand and ran forward a few more steps and said, "Sister, you're stabbing the ground hard now."

"Where can you just stab the ground?" Catherine didn't ask why at all, and drew her sword and looked for the landing point.

"Just put it here." Vivian said, pointing to the ground.

Catherine raised the sword and concentrated silently. After several breaths, she shouted loudly and stabbed the metal ground hard. With the infusion of Dou Qi, the Knight's sword penetrated deep into the metal ground about half a meter before stopping.

"That's great, enough." Vivian clapped his hands happily: "Sister gives me the sword."

Catherine handed over the Knight's Sword and looked at Vivian in confusion with the method of drawing a magic array out of thin air that she learned from Panis not long ago, condensed magic silk threads and carved several magic array runes on the sword surface of the Knight's Sword. Finally, she couldn't help asking: "Is this...need for me to cooperate? I don't understand magic at all."

"It's okay, just follow my instructions." Vivian once again raised to the top with the activation rope, took out a pen and drew a mark on the roof of the corridor, and directed the activation rope to retreat by two meters: "See that line. After I shouted to stab, no matter what you do, after five seconds of hearing my shouting, you must ensure that your sword stabs into that position, not one second later. When I shouted to draw the sword, pull out the sword immediately, and it can be done."

Catherine silently repeated Vivian's request, practiced it in her heart, then nodded and said, "No problem."

Vivian also put away the laughter on her face, her palm pressed against the roof, closed her eyes and felt the flow of magic in the magic channel covered with metal, and silently calculated in her mind. Suddenly, she opened her eyes suddenly: "It's now, thorn."

When Catherine heard "It's now", she had already poured her fighting spirit into her whole body and jumped high in the air. When she heard the instructions of the thorn, the knight sword in her hand suddenly pierced into the position with thin lines, which was exactly the same.

"Push the door." Vivian remembered that he had forgotten to instruct Lina and Panis to push the door at any time. He was about to worry, but found that Panis seemed to be ready and stood by the door. He immediately pushed the door when he heard her instructions. The door, which had been unable to move no matter how hard he pushed it, as the knight's sword pierced into the roof, became open as soon as he pushed it. Panis felt that he had no effort to push it. The metal door, one meter thick, opened lightly inward, and there was no sound in the whole process of opening the door.

"Draw the sword, hurry up." The Knight's sword was stuck on the roof at this time. Catherine held the sword in her right hand and hung it under the Knight's sword. Hearing Vivian's shout, Catherine used force with her right hand, flipped her body up, stepped on the roof with her feet to leverage the force, easily pulled out the stuck Knight's sword, curled up in the air, and fell steadily on the ground.

"Perfect, finished." Vivian also landed on the ground, and did not rush into the door. She ran to her backpack and took out some items, and rose back to the gap where Catherine pierced the roof, and was busy for a while. When she returned to the ground again, there was no trace of the gap in the roof.

"Awesome." Lina, who had no help at all, consciously took on the role of satisfying the little girl's vanity, and praised, "I am a genius, how did you do it?"

"Hehe." Vivian replied with a proud smile: "Actually it's quite simple. I deceived the magic transmission channel of the Mage Tower." Seeing that everyone was not very understanding, they continued to explain: "I just found a magic channel that supplies the magic lock energy of the gate. If the channel is cut off rashly, the blockage of the magic transmission channel will cause an alarm and activate the defense system of the entire Mage Tower. So I used deception methods. First, I blocked the channel for about half a second with my own magic power. If it only has half a second, it will be regarded as a normal channel blockade by the security system and ignored it. Then, in this half a second, my sister inserted the sword into the position of the channel. The sword was carved.

It is a magic absorption array, which also has a deception effect. The magic power sent from the magic channel will be absorbed by the magic array. At the same time, the magic array transmits deception information, causing the security system to mistakenly believe that the magic power has been transported normally, so that the magic lock on the door will temporarily lose its energy supply and is easily opened. However, this deception can only last for a few seconds, and it will be identified by the security system after more than the time. Only then must open the door at the fastest speed, and then draw out the sword to restore the magic power in the channel to flow. I am talking about these simply. The actual calculation is very troublesome, so don’t close the door, if it closes, it will be done again.”

"Then let's go in. We've gone through a lot of trouble to open the door. We must see what secrets are hidden inside." Lina took back the book she was holding in her hand, and picked up the mace on her waist and waved it: "If there is still nothing inside, I'll smash this room."

"Don't go in first." Panis reached out and stopped Lina: "There are many corpses inside, and they are closed. Let's go in after you're relaxing."

"There are corpses in it, too?" Catherine realized something: "That is, it has not been cleaned up?"
