Soon, the entire interstellar knew about the "nerve gas scattering projectile", and Principal Wei Chi was full of gloom in his office.

"Principal Wei Chi" Professor Nangong said, originally wanting to buy some more time for investigation, but he had to tell the truth, "I still haven't found out the source of this scattering projectile." ”

"No need to look it up." Yu Chimu lowered his head and waved his hand to Professor Nangong, "Let's think about how to solve it first." ”

Professor Nangong originally wanted to add something, such as the fact that he had recently discovered some suspicious things and suspicious people on campus, but he never said it.

After all, these things don't seem to have any direct connection with the scattering projectile.

"Nangong" Yu Chimu raised his head, cleared his throat, and said in an unhurried but extremely majestic tone, "Find the antidote as soon as possible." In addition, the headquarters of the submarine school is closed. ”

Soon, the defense system of the submarine school headquarters was activated.

First, the submarine dome is closed.

The dome of the sea floor is a layer of transparent objects, whether it is seawater, guns and ammunition, or some other conventional combat weapons in the interstellar space, it cannot penetrate it.

The dome is a huge hemispherical shape, and at the highest point of this sphere, there is a "ladder to heaven" that connects the sea floor to the sky.

In other words, the closure of the submarine dome is the closure of the "ladder to heaven".

This means that a fish, a person, or even a grain of dust cannot do without the dome of the seabed.

In addition, all the colleges in the headquarters of the submarine school are closed, and all students are only allowed to stay in the teaching building, and the school will send someone to distribute a certain amount of nutritional injections or nutritional biscuits to them.

Students are not allowed to sleep during this time, and the 24 Interstellar Hours must be turned on.

Principal Wei Chi and Nangong Tian would meet in the video security control room of Yuxing High School every half an interstellar hour to discuss the current state of the students.

On the other hand, Teacher Panda and Professor Shangguan are guarding their respective colleges.

Now the gate of the college has opened the most urgent identity verification mode, and every student or some other staff member who passes through the gate must be authenticated accordingly.

Teacher Panda walked around the lab in a white coat, and the pale look on her face had already revealed the anxiety in her heart.

"Luo Chuan is no longer in the laboratory, and it happened to be missing when the 'nerve gas scattering bomb' exploded." Teacher Panda stopped, her gaze resting on the glass bottles in the lab, which contained some lifeless embryos, and the smell of formalin made her nose uncomfortable.

"It can't be a scatter projectile released by Luo Chuan, right?" Teacher Panda's eyes were full of suspicion.

However, as far as she knew, Luo Chuan didn't have any relevant knowledge of chemistry and biology at all, let alone any poisonous gas projectiles, but did he understand the knowledge of cell division?

Moreover, it was easy for him to escape, and he didn't need to make such a big effort to release poison gas projectiles at the risk of being expelled.

"I can't say." Teacher Panda said softly.

The undersea dome with the defenses turned on was eerily silent.

In a corridor of the School of Biology at the headquarters of the undersea school, Nangong Tian and Luo Chuan were walking forward weakly.

Nangong Tian felt that his mind had slipped into a half-asleep state of vertigo, and the world around him was completely foggy.

He felt his throat crack and his mind dizzy.

He told himself he had to stop, but he fell asleep.

"Nangong Tian."

It was Luo Chuan's voice. It was so faint that he almost closed his eyes.

"Wake up." Luo Chuan used all his strength to concentrate, and he shouted again.

Nangong Tian opened his eyes and was surprised to find that he was not dead.

After all, the "nerve gas scattering projectile" is poisonous and cannot kill people, it will only destroy the human nervous system to the greatest extent.

Luo Chuan struggled to open his eyes and walked to the gate of the School of Biology with heavy steps.

Luo Chuan raised his head and saw that the door of the Biology Academy was closed.

"Authentication." The four words are written on the transparent metal gate.

"Ogawa." Nangong Tian said, his eyes were struggling to open, he felt a stuffiness in his chest, and his whole body fluttered, and then, he whispered, "Look, you have to verify your identity." ”

Luo Chuan followed the direction of Nangong Tian's finger and looked at the gate of the Biology Academy.

The gate is made of a rare and transparent metal from the stars, and its thickness is only 0.3 mm.

However, no one should underestimate this thin 0.3 mm.

It is said to be transparent metal that all conventional weapons in the interstellar world cannot penetrate and break.

He reached into his pocket and pulled out the only two nutritious biscuits he had just pulled out of the lab.

He took out one of the nutritious biscuits and handed it to Nangong Tian behind him, "Eat it." Luo Chuan said, then stuffed another nutritious biscuit into his mouth, and then let out a crisp crunch.

Nangong Tian raised his head and saw his friend biting on a nutritious biscuit.

Then, he quickly took the nutritious biscuit from Luo Chuan's hand and stuffed it into his mouth.

This is not the first time that I have chewed this food that is famous throughout the stars, and it has no special taste, except that it is sweet and sweet.

On an ordinary day, he simply couldn't swallow such a high-sugar and high-calorie food.

But this is not the case.

In Yuxing High School, especially in the Biology Academy, he had lost his advantage as the sole heir of the Nangong family.

Nangong Tian took another bite of the nutritional biscuit, and there was an indescribable discomfort in his heart.

Whimpering, he gobbled down a nutritious biscuit.

Luo Chuan chewed the nutritious biscuit as fast as he could, and he realized that he could truly feel a fountain of power pouring into his body.

"Nutritional biscuits are quite quick to replenish energy." Luo Chuan said secretly.

Then, he summoned the last remnants of strength from all over his body, concentrating all this power gathered from all over his body in his right hand.

He rolled his eyes and slowly stood up, the feeling of weakness from the gas bomb not yet fully subsided.

It felt like most of the inner strength in his body had been sucked dry, and it was as if he had only a few bones and a skeleton left to keep himself on his feet.

Soon, he was on his feet, and in just a few seconds, he felt much better than he had been in the lab.

Luo Chuan slowly stretched out his right hand, and the green film covering the surface of his right hand loomed.

"Spear of Destruction"

Luo Chuan shouted.

He closed his eyes, and an image full of light appeared in his mind, and the feeling made him seem to forget about himself.

The powerful recoil of the Spear of Destruction forced Luo Chuan back several steps.

The light was so dazzling that he couldn't see it.
