"Those three······ Where did the people go?" Lang Feng looked at Duan Ning on the side, with a look of disbelief, this medical room is closed, and the level of technology is also high-class, the three dead people ran away without any alarm, what kind of trouble is this.

"They didn't run!" A burst of very special energy surged from Duan Ning's body, and after some probing, his face changed greatly, and he immediately broke open the storage device on the wall of the medical room, took out four button-like things from it, and threw three of them to Lang Feng and them.

It is an emergency isolation device, and when you press the red button in the center, it will appear a crystal layer that clings to the body, and is able to block out the air and everything from the outside.

Although Lang Feng didn't know what was going on, he still triggered the button very quickly, and it wasn't until the four of them had it right that Duan Ning turned on the special light on the wall and found that it was covered with some very fine dust, and these dust were actually alive.

"This is what those three corpses have become, seal off this room, and deal with those infected students as soon as possible!" Duan Ning immediately made a decision, and immediately announced the order through the intercom system on the wall, and in less than a few minutes, this medical room had completely turned into a forbidden area, and everyone could only enter and exit.

"Next, we're going to save ourselves!" Duan Ning looked at Lang Feng with some apologies, if he hadn't insisted, Lang Feng wouldn't have followed him on this trip to the troubled waters, but it was too late to say anything now.

"General Duan, you must have experienced countless life and death situations in your life, but now is not a good time to stand here, so don't be too pessimistic, don't forget, I'm still a soul master!" Lang Feng calmly looked at the dust in the room, and immediately communicated with Xinghe, hoping that he would search for ways to deal with these microorganisms in his memory.

"Hehe, the little guy is in danger, if there is any way, let's take action quickly, I'm afraid this thing on our body won't last long, and I don't know if we're already infected!"

Duan Ning's voice was still calm, with the air of a general, Lang Feng didn't say anything more, and immediately took out a utensil from the equipment box, collected some dust, and prepared to do an experiment.

"The kamikaze of the dog day is miscellaneous, all of them have changed the world, you still don't change your dead nature, you are still playing bacteriological weapons, and when you have the opportunity in the future, I will definitely go and level your empire, how can such a dirty race deserve to live in the world!"

Constantly scolding in his heart, Lang Feng used all the means he could use one by one, and finally was pleasantly surprised to find that he did have a way to gather the dust again, but he didn't dare to do that directly.

Because, this requires the use of his two spirit roots, one of which is the dark spirit root, just now, Lang Feng quietly used a trace of dark and light mixed energy in the cup, and immediately found that the dust in the cup immediately gathered together, and the outside of the cup also moved quickly to this side.

After some ideological struggle, Liu Yue still decided to take a risk, he pretended to be tired and looked at the other three, and then pretended to be very uncertain and asked, "Which of you has a treasure that can stimulate the dark energy?"

The word dark system is definitely a taboo word in the hearts of this group of people, Duan Ning and Vice Dean Qin simply shook their heads when they heard it, but that Qingkui looked at the three of them with some hesitation.

"It looks like Dean Qingkui has such a thing!" Lang Feng was ecstatic in his heart, as long as he disguised himself a little now, he should be able to keep his secret.

"I have a dark spirit crystal here, but it has been embedded in a dagger, and this dagger is very evil!" Qing Kui twisted slightly, and Lang Feng concluded from his face that he probably wasn't telling the truth.

"You old thing, if you have it, take it out quickly, it's a big deal that I can find you an equivalent one in my nebula's treasure house when the time comes!" Vice President Qin was very anxious, and he was very disdainful of this slow swallowing of this product, thinking that he was reluctant to give up the treasure.

"No, that thing is very evil, and two days ago, it had an accident!" He said this and immediately attracted the attention of Lang Feng and the three of them, especially Duan Ning, who immediately walked up to him and stared at him: "Vice Dean Qingkui, you tell me honestly, after your so-called accident, did anything unusual happen to your students!"

Lang Feng also wanted to ask this question, because in the process of Lang Feng confirming the dust just now, although Xinghe did not give a specific solution, he told Lang Feng that this was a very ancient virus, and the way of outbreak needed to be stimulated by a special energy.

"General, this thing is not mine, I also got it after I came to Tianliang!" Qing Kui did not answer Duan Ning's question directly, but this just proved Lang Feng's guess.

At this moment, he couldn't care about the elders and young, so he immediately rushed over, grabbed Qingkui's arm and said sharply: "Hurry up and give me that thing, you have killed your three students, and you are guilty of a lot!"

Lang Feng wanted to say that he was colluding with foreign clans, but in the end he held back, because Duan Ning's body had already surged out of a strong internal force, as long as this Qingkui said a wrong word, what was waiting for him would definitely be the treatment of a different body.

In the end, Qing Kui took out the dagger tremblingly, and Lang Feng could see where it came from at a glance, and the material was clearly the same as the material used on the starship in the Extremely Cold Land.

And under the scanning of his star soul power, there was also a hollow tube in the blade of the dagger, which looked like there was something in it originally, but now it was empty.

"Bastard, I'll tell Dean Jialan about this, you can explain it to him then!" Duan Ning was furious, shook his hand fiercely, and then turned to Lang Feng and said sincerely: "Please." ”

Lang Feng nodded, holding the dagger, the light energy and the dark energy fused, directly stimulating the dark spirit crystal on the dagger handle.

Soon, the area around the dagger suddenly became dark, and eventually a scalp-tinging fist-sized ball of dust gathered on the blade of the dagger.

"What are you going to do next!" Duan Ning watched Lang Feng stop, and immediately asked it, and finally at the latter's request, he found a highest-level sealed jar and threw the dagger into it.

After repeatedly inspecting the room and finding that the dust had been completely absorbed, Duan Ning lifted the alarm, and then after Lang Feng did a comprehensive inspection of the three of them to confirm that they were safe, he pushed all the infected people into this room.
