What comforted Luo Chuan was that the pain in his head had disappeared.

He listened intently to the joke that Nangong Tian was telling.

Nangong Tian, like him, was placed in the laboratory of the School of Biology.

It is rare that in such an almost prison environment, Nangong Tian can still tell jokes.

Luo Chuan followed the rhythm of Nangong Tian's speech and smiled, but the matter in his heart was still not resolved.

Luo Chuan's eyes were fixed on the ceiling, "Where is it?" ”

He was already very familiar with the grass and trees in the School of Biology, whether it was a teaching building or a laboratory, there was no trace of Roland.

Luo Chuan's mouth moved, he wanted to say something, but when Roland's image suddenly jumped into Luo Chuan's mind, he lost the desire to speak again.

"Where the hell is it?" He forced himself to say.

"I said," Nangong Tian said, and then stood up, "You're stumped me." ”

"You want to open a little." Nangong Tian said.

"It's fine."

Nangong Tian walked away, and Luo Chuan sat up from the experimental table, staring at the floor in a daze.

He closed his eyes for a moment, trying to appreciate the rare serenity, but when he saw Roland's green headband again in the deepest part of his soul, he opened them again.

He had to adjust himself right away, if he still wanted to see her.

Hunger.

It's like a beast inside you, it's eating away at your body and even your soul.

Luo Chuan hadn't eaten for a whole day, the kind of hungry beast in his body was gnawing and scratching, trying to get out of his stomach, and he could feel every interstellar hour, every interstellar minute, every interstellar second.

He walked out of the lab.

Luo Chuan watched as the students in the School of Biology building walked around in white lab coats, their heads hanging low, their chins shrunk one by one, as if every step they took was crucial.

Luo Chuan felt a little strange, with the style of Teacher Panda, he would definitely send someone to watch him in the laboratory, and he didn't want him to move around.

What's going on today?

One by one, the students licked their lips, their skin was pale, their eyes had lost their luster, and they looked weak.

Truth be told, he was ready for battle, and if a student stepped forward to stop him, he would use all his strength......

Strangely, no one came to stop him.

This question made him very curious.

He and Nangong Tian walked to the park of the headquarters of the undersea school, and kept receiving water from the faucet in the park to drink, but drinking water could not drive away the beast at all.

They went back to the lab to find a few nutritional injections from the laboratory, even if it was a pack of ordinary nutritional biscuits.

They ventured back here.

"Don't you think it's weird?" Nangong Tian asked, his lips were a little pale, and he hadn't eaten for a day. Then, lowering his voice, he said, "The Biology Academy seems to be an unlocked cage. ”

"Hmm." Luo Chuan said, looking at the pedestrians in the corridor alertly, "I also feel strange. It could be something happened, but I'm not sure. ”

"I said," Nangong Tian said, "Let's find some nutritional injections in a while, and nutritional biscuits will be ready." ”

I'm already hungry enough to find a nutritious cookie.

To be honest, there are still a lot of delicacies in the interstellar world, such as hell chicken, all-metal set meals, earth roast duck, moon ice cream, and you will drool when you think about it.

But isn't there nothing to eat?

Luo Chuan walked in the corridor, observing the students in the corridor as he walked, he felt that something was going on in this academy, and as for what happened, he still didn't figure it out.

It's just a reason to come back to find food, and the most important thing is that he still wants to come back and investigate again, maybe there will be news of Roland.

"I smell something." Nangong Tian said, his nose moving, as if he was trying to sniff the smell in the air.

He smelled the smell of disinfectant water, the pungent smell of formalin, the smell of perfume used by the girls, and the smell of sweat on the boys.

However, none of these seem to be the main smells.

Nangong Tian raised his head, his eyes were full of fear, and he felt that the smell came from some kind of poisonous gas.

"Nerve gas scatter projectile," Nangong Tian shouted.

"The nerve gas scatter projectile, which is a more toxic nerve agent than **, is one of the deadliest chemical weapons. It is also a colorless, odorless, oily liquid that turns into a gas once it comes into contact with oxygen. Industrial products are yellowish, yellow or brown, and a small amount of mercaptan will be decomposed during storage, so it has a foul smell, mainly because of the liquid to cause poison on the ground and objects, which can be transmitted through the air or water source, and is almost imperceptible. Human skin contact with it or inhalation can cause poisoning, and headache and nausea are the main symptoms of infection with this poisonous gas. Poison gas can cause central nervous system disorders, respiratory arrest, and eventually death.

In all kinds of chemical agents, according to the length of time of its killing effect, it is divided into temporary poison and persistent poison, after the persistent poison is applied in the form of droplets or fine powders, resulting in ground poisoning, personnel contact poisoning, the effective killing time is more than 60min, the poison used is mostly high boiling point, non-volatile liquid poison such as mustard agent, because it causes long-term poisoning in the area, personnel should not enter the area immediately, so it is mostly used in defense or retreat, in order to hinder, delay or contain the opponent's military operations, The fine powdery poison settles on the ground after being applied, and flies again when people or vehicles pass through or when the wind speed is high, so it can cause poisoning on the ground and air for a long time. Nangong Tian said.

"No wonder the students in this school building are so sluggish." Luo Chuan said.

"If it weren't for the fact that they were Star Protectors, they would have fallen a long time ago." Nangong Tian said, "We have to get out of here as soon as possible." For a while, you should pay attention to your breathing when you walk, and do not inhale poisonous gases. ”

Luo Chuan looked at Nangong Tian with wide eyes, he was not ready to say anything.

But there was a little doubt in his heart, that is, why did Nangong Tian still breathe as freely as he did now, when he felt that even the Star Protector felt unbearable when he smelled it.

In order not to inhale the poisonous gas, Luo Chuan did not express the doubts in his heart in the end.

But where did this scatterer come from?

It stands to reason that the Faculty of Biology is the academic powerhouse of Yuxing High School, with a support system and a defense system, which shows that the Faculty of Biology must have considered the bomb attack and the dropping of poison gas bombs, but the alarm of the Biology Academy did not sound, and the students walked around the corridor as usual, as if they did not smell the smell of poison gas.

Thinking of this, Luo Chuan couldn't help but speed up his pace.
