After finishing the enemy, Lin Shaorong immediately followed the method taught by Professor Qi to find a camera obsca located in the far corner of the research library console.

At first glance, the camera obscura is simply a mediocre box, and there is nothing in it, and the demons may have discovered the existence of the camera obscura, but as everyone knows, this thing is only one of the key elements.

Move the camera obscura out and move it to the center of the entire research library, the center position has exactly four corners, the size of the camera obsccura is just enough to align with the four corners, and then adjust the direction to aim at a certain point of light on the wall, and press.

The four corners of the center are activated, and the lines composed of energy go towards the four corners, and the lines reach the corners of the walls and extend in different directions again, and the four walls of the research library are activated, and the walls are connected by various energy lines, which are constantly transmitting.

A light screen also appeared in the center, displaying all the materials and research content of the entire Fourth Pair of Demon Research Library.

Most of the archives are multi-encrypted, and they can't be accessed without a key, but that's not the point, the point is that after activating the entire research library, these energy transmission lines on the walls hide hidden mysteries.

After Lin Shaorong groped on the wall, he finally found a line that Professor Qi said, that line is one of the few connected three energies, one of which is to the central control panel, and the other is to the exit gate, and this last one is crucial, it extends from the wall all the way up.

Although there are many lines that are the same as it, according to Professor Qi, there are three types of line energy connected, one control panel, one controlling the exit, and the last one controlling one hidden source energy.

"Professor Qi said that there are more than ten hidden source energy in this research library, because many of them are connected to self-destruct devices, so they must be confirmed before they can be activated, and if the activation is wrong, then everything in the entire research library will be automatically destroyed." Lin Shaorong was very careful to confirm the accuracy of this line.

After constantly recalling what Professor Qi said and comparing it repeatedly, Lin Shaorong was finally sure that it was the line in front of him, so Lin Shaorong came to the control panel, found the line activation option and pressed it, and all the energy lines in the entire room immediately popped up on the central light curtain.

After careful identification, Lin Shaorong activated the line he had found.

"Warning, warning, you are activating the source energy of the fourth pair of demon research library, if it is a mistake, please cancel it immediately." Soon sirens sounded throughout the room.

Looking at the two options of activation and cancellation popping up on the light curtain, Lin Shaorong directly chose to activate without hesitation.

"The source energy of the fourth pair of demon research libraries is being activated, and the source energy line is being confirmed, line 1 is normal, line 2 is normal."

Listening to the alarm sound from the research library, Lin Shaorong was on pins and needles, cold sweat had slipped down his face, and he was very worried about whether the route he chose was correct.

"Line three is normal."

Hearing the last siren, this made Lin Shaorong breathe a sigh of relief, looking at the activated line on the wall, Lin Shaorong walked over and pressed the light curtain that popped up on the wall.

After answering the key question, a beam of light was directly illuminated from the top of the other side of the central light curtain, and a black square box was suspended in the middle of the beam.

"No wonder the demons haven't found it for so long, this thing has been teleported into this research library boundary space, if the method is not right, it is very likely that the boundary space will be automatically destroyed directly, this secrecy work is quite in place." Lin Shaorong sighed and stretched out his hand towards the beam.

After taking out the black square box, the beam disappeared immediately, feeling that the black square box in his hand was cold and cold, and checked the weight, Lin Shaorong really didn't see what this thing was for.

But after all, he found it, so Lin Shaorong put away his things, and when he was about to leave, he seemed to remember something.

When he came to the control panel to operate, seeing the message popping up in the central light curtain, Lin Shaorong smiled and operated it again.

After doing this, Lin Shaorong left with the black square box, came to the outside of the passage, and noticed more than a dozen demon corpses lying on the ground, and then looked at Zhou Wen next to him, which also made Lin Shaorong shiver.

Lin Shaorong was very happy, fortunately it was Zhou Wen who came with him, otherwise it would only be more difficult to solve these troubles when he encountered them. But after thinking about it again, it was also because Zhou Wen came with him that he would encounter these troubles, and if Lin Shaorong went alone, he would be more careful or avoid these.

The matter has come to this point, Lin Shaorong can't say anything, seeing that the matter has been completed, Zhou Wen also came to his side and asked, "You haven't encountered any trouble, have you?" ”

Lin Shaorong shook his head and said, "I solved a few demons in it, and I got the things." ”

After listening to this, Zhou Wen was also overjoyed, and immediately asked Lin Shaorong about his next plans.

Lin Shaorong said: "Let's go directly to the control room and make a deal." ”

Zhou Wen heard that Lin Shaorong was going to trade with the demon clan and scolded angrily: "Are you crazy? I don't allow you to trade with them, we finally got something, we should let them release them first, and then we can make plans. ”

Lin Shaorong shook his head and calmly explained to Zhou Wen.

"Aren't you worried about your students? I could have given you something right now and left, I shouldn't have said this as an outsider, but I still think that human life is at stake, even if something is given to the demons, we must save people, if you think things are more important than human life, I will give you things now. Lin Shaorong took out the black square box and handed it to Zhou Wen.

Zhou Wen also fell into deep thought when he saw this, and Lin Shaorong didn't take his hand back when he saw that Zhou Wen was thinking.

After a long time, Zhou Wen sighed and said:

"I know what you mean, I was derelict in my duty, at first I thought from the perspective of the association, but now that I am an instructor, I have an obligation to protect the safety of students. You reminded me that I almost went astray, thank you. ”

Lin Shaorong saw that Zhou Wen had already made a decision, and a smile appeared on his face, he admired this kind of person who put life first and considered it.

Only by cherishing life can we have a future, even if there is little hope, as long as people are still alive, there will be opportunities.

Lin Shaorong put away the black box, and the two of them also decided to go to the control room immediately.

When passing by a few rooms, except for the messy room left, the demon clan was completely gone, which also made the two of them wonder.

Approaching the control room, the two of them already understood what was going on, the demons already knew their whereabouts, and they probably also knew that Lin Shaorong and the others had found what the demons wanted.

So now all the demons outside the control room are standing on both sides of the passage, and a path is deliberately made in the middle for Lin Shaorong and the others to pass.

Zhou Wen wanted to make a move, but was stopped by Lin Shaorong and said: "Don't act rashly, we don't know what the other party's idea is." ”

Lin Shaorong felt that he couldn't act rashly now, as long as the things were still in their hands, then there was room for maneuver.

At this time, a voice came from the control room: "Since you are here, come in, I will not make a move on you." ”

After Lin Shaorong and Zhou Wen saw that the other party had already opened their mouths and looked at each other, they finally decided to walk over.

The demons on both sides were staring at the two of them with angry eyes, but for Lin Shaorong and them, now they have the capital to negotiate, as long as there is no accident, then the next thing is to see who has the initiative.

After coming to the control room, the first thing I saw was Yuan Xing standing in the middle, and next to Yuan Xing was Ci Lu, and not far behind them was the person who was being imprisoned, and then the surrounding demons surrounded the two of them.

Yuan Xing waved his hand, and although those demons were angry, they still dispersed.

And everyone in the cage was also very excited when they saw the people coming, and some students screamed.

"Instructor Zhou Wen."

After Zhou Wen looked at them and gave them a calm look, the restlessness of the cage gradually subsided.

After the two of them swept their eyes across the control room, there was no movement, and both sides were silent, as if they were waiting for the other to speak first.

However, there were always people who couldn't bear it, and Yuan Xing was the first to speak: "What about things? ”

Seeing that someone spoke first, Lin Shaorong also calmed down his inner emotions and reached out to take out the black square box.

"That's what you want?" Lin Shaorong flipped the square box in his hand and said.

"Hmph." Yuan Xing snorted coldly, and with a wave of his big hand, he dispersed the prison cage, but he used another trick, and a layer of substantial magic power fluctuations surrounded everyone. When a discerning person sees this fluctuation, once it touches it, it will be either death or injury.

"I really didn't expect you to get here, and I didn't expect you to be the first to get what I want." Yuan Xing looked at the two of them and said.

"There's so much you didn't expect." Lin Shaorong said sarcastically.

"I don't want to argue with you, handing over people with one hand and delivering goods with the other." Yuan Xing seemed to be very impatient.

"It's in my hands, and I'll decide what I want." Lin Shaorong does not intend to compromise on this.

"Hmph, let me tell you one thing first, I've already made a deal with your professor." Yuan Xing pointed to Professor Qi on the other side.

And everyone looked at Professor Qi, and Professor Qi, who was surrounded by gazes, did not dare to respond to these gazes, and remained silent.

Yuan Xing saw that Professor Qi didn't intend to explain, so he said: "This deal is very simple, he is also to protect you, the content is that after your rescue force arrives, he will tell you the location of the things and let you take them and exchange all the hostages with me, a very simple deal." ”

After listening to Yuan Xing's words, everyone was also a little relieved, from Professor Qi's starting point of view, it was indeed correct, only in this way could the safety of others be guaranteed.

"The deal he made with you doesn't mean that I want to trade with you, I found something, so I don't plan to compromise like this." Lin Shaorong seems to want to occupy the right to speak, so he doesn't plan to stop like this.

"Hmph, the bugs haven't been wiped out, and you're so complacent when you get your hands on them." Yuan Xing sarcastically mocked Lin Shaorong, as if to express that he had seen through everything.

"yes, I didn't expect it to be so easy, maybe your strength is just that?" Lin Shaorong said back.

Hearing this, Yuan Xing laughed, and the irony in the laughter was even stronger, which made Lin Shaorong a little annoyed, but there was still no expression on his face.

The laughter echoed unbridled throughout the control room, and after a few moments, it gradually subsided.

Yuan Xing looked at Lin Shaorong and said, "More things are better than less things, I just let the mouse jump for a while, but I didn't expect to kick my nose in the face." ”

After speaking, Yuan Xing's eyes were surging with chaotic magic, and he looked directly at Lin Shaorong again, and Lin Shaorong was also looking at Yuan Xing at the moment.

The trapped Meng Yunxue was shocked when she saw this scene, and shouted and reminded: "Don't look at him, you will die." ”

But it was not too late for the words to be spoken, the eyes of the two were already facing each other, and the exchange of eyes between the two sides made Meng Yunxue tremble.

No one can understand why Meng Yunxue is so excited, because she once looked at Yuan Xing, the kind of immersion in chaos, loneliness and confusion destroyed the psychological defense line again and again, as if telling herself that only embracing death is the best relief.

At that time, the other party was just torturing her, and she relied on her strong mind to fight desperately to get out of the predicament of falling into the abyss.

But now that she saw the confrontation between Lin Shaorong and Yuan Xing, the momentum was not towards torture at all.

The magic power that could be directly felt from Yuan Xing's eyes, it was obvious that the other party was making a killing move with the determination to kill.

What worries her the most is that she has already sensed the strength of the other party from the time she saw Lin Shaorong, although she did not perceive the boundary point and was not sure whether the other party was a world protector, but she could be sure that Lin Shaorong's strength was not very strong.

Now that the two sides are in confrontation, she can only pray, and she doesn't even dare to see with her own eyes what will happen next.

And Yuan Xing and Lin Shaorong just looked at each other, and the exchange of eyes made Yuan Xing frown.

He felt that something was not normal, Yuan Xing could see from the fluctuations of the other party that Lin Shaorong was like an ant.

"Why doesn't the Eye of Chaos work, and what's going on with the kid on the other side who doesn't admit defeat." At this time, Yuanxing's heart is very exciting.

At this moment, everyone's attention was on the two of them, although it was not clear why the two people were just looking at each other, but the atmosphere was obviously very wrong.

Except for Meng Yunxue, the exchange of eyes between the two people obviously made it a little difficult for everyone else present to understand, but Lin Shaorong knew the danger in it, but he was still calm and calm, and it was obvious that the other party didn't know his depth.

Seeing that the two sides were at a stalemate, Lin Shaorong directly threw the black box in his hand to Zhou Wen, and the two seemed to have a heart, and Zhou Wen understood the moment Lin Shaorong threw it out.

Although the two have not been in contact for a long time, they have been fighting side by side since they entered the forest, so that the two also have a tacit understanding.

At this moment, Lin Shaorong meant, Zhou Wen understood at one point, after getting the black square box, he directly showed the realm in his hand, a wind wheel surrounded the black square box, and the air flow brought up by the rotation touched the square box and produced sparks.

When Yuan Xing saw the other party act like this, he also immediately urged the magic power, and the magic fluctuations surrounding the hostages began to contract, although they did not touch it, but the pressure quickly caused some people to cough up blood and make painful sounds.

This move of both sides made the other party nervous, and both sides wanted to take the initiative, but neither was willing to give up under the mutual test.

Although Lin Shaorong planned to trade with the other party, he also wanted to gamble, bet on the importance of the black square box in the other party's heart, and bet that the other party would not dare to make a big deal and lead to disputes between the two worlds.

As long as the bet is successful, then he will take the initiative next, and then he can make a deal and open unreasonable conditions.

Lin Shaorong passed a look to Zhou Wen.

Zhou Wen also understood, but looking at the shrinking magic fluctuations and the painful expressions of the students, Zhou Wen was still hesitating.

Lin Shaorong gave Zhou Wen an affirmative look again.

After Zhou Wen comprehended it, he gritted his teeth and made a desperate bet, and the wind wheel in his hand began to shrink, and the wind blade cut into the square box and made a somewhat harsh sound.

"That's enough." Yuan Xing was a little anxious when he saw that the square box came into contact with the sparks that popped out of the wind blade, and he shouted out directly.

Lin Shaorong saw that the other party was relieved and signaled that Zhou Wen could stop, and Zhou Wen slowly spread the wind wheel and hovered around the square box.

And Yuan Xing also relaxed the magic fluctuations, and those who were tortured immediately coughed and whezed, but some of them continued to cough up blood.

Zhou Wen saw that those people were being tortured, and his breathing became a little irritable, but Lin Shaorong kept signaling him to calm down, and he could only suppress the anger in his heart.

Seeing that the other party stopped moving, Yuan Xing also slowly exhaled and said, "What do you want?" ”

Hearing this, Lin Shaorong was relieved, this bet, he was afraid that he would lose the bet and let innocent people die, but the final result satisfied him.

Lin Shaorong replied: "How about you answer me a few questions first?" ”

"Say." Although Yuan Xing was still thinking about why the Eye of Chaos had no effect on the person in front of him, it was not good for him not to answer since the other party began to ask.

Lin Shaorong looked at the other party's angry but helpless expression, and the corners of his mouth also hung a sneer and asked:

"What the hell is this black box?"
