Steel steam and flame

The fragments of the glass test tube were still lying on the ground. The light cyan liquid contained inside was very viscous and adhered to the test tube rack support. Because an abnormality was detected in the room, the air circulation system and the door were all locked and airtight. There was a faint pungent smell at this moment. Still smell it.

The broken glass test tube was on the side of the wall closest to the elevator shaft. But Professor Mosier circled around the pile of fragments, his eyes getting brighter and brighter, as if he had found something of interest. He raised his head and looked at the middle of the elevator shaft through the thick walls and rock formations, and his basic guess had already appeared in his mind.

"By the way, the ultrasonic vibration machine in the laboratory base is activated at full power. Can it shatter these glass test tubes?"

"No, even if the safety device is removed and allowed to run beyond the limit, the effect of shattering the glass cannot be achieved. The performance of the machine itself limits it." The skinny assistant pushed the glasses, which involved his own job. In addition to assisting in experiments, all the machines and equipment in the laboratory base are debugged and managed by him. No one is more familiar with these machines than him. "They were purchased from the Far Sea Commonwealth and are subject to national control restrictions. In order to prevent them from being bought, disassembled and transformed into Weapons, so many data performance requirements are strict. The manufacturer is not a huge company, so it should not dare to do this kind of thing."

"That's the answer." But Professor Mosier nodded with satisfaction, "Next, help me call up the surveillance images in the tunnel from the analysis machine. The time period is still within five minutes. Bennett, this matter Just digest it among the four of us, without informing those in the town. In addition, take a look at the storage status of various materials in the laboratory base. Many materials should reach the warning level in a few days. You classify them and create a List.”

"Got it." The man named Bennett nodded. He is a researcher here, but Professor Mosier is both his boss and his teacher.

"Didn't the town warehouse have a new group of protectors and administrators?" But Professor Mosier continued, and walked out of the room with Bennett and the others, "Every one or two days, let a few of them go. Deliver the corresponding supplies separately once. This is something that has been tacitly agreed upon. These young people, we can help as much as we can. However, there is another thing that I need you to help me prepare for, especially Zagavar. "

When the skinny man heard Professor Kemosier call his name, he was obviously confused and nervous. He nodded and waited for the next words.

"You are most familiar with machinery and equipment. I want a kind of testing machine. Just two or three of them. As long as you can get it, you can use the things used in the laboratory base to do it." But Professor Mosier spoke very slowly. , "It should be very simple for you, a sound wave detector, just the kind that usually measures the level of noise. But the range I need is very large, and the sensitivity must be extremely good. The kind that can capture both low waves and ultrasonic waves." There is no need to make a 'beep' sound after testing, leave a record silently, or send out vibration feedback."

"Are you having any difficulties? If you need help, just ask?"

Zagavar was lost in thought. After a while, he raised his head and said, "It may be necessary to dismantle the two monitoring machines in the shock chamber, and they cannot be restored afterwards. Some other small parts need to be purchased in the nearest city. They are easy to buy, and they are all They are some commonly used originals.”

But Mosier nodded: "Bennett, after Zagavar gives you the list, let people in the town buy it for you."

"How long will it take?" But Mosier turned his head and looked at Zagavar, his smile even wider.

"Three days."

"Okay, Bennett, let a few people from the town warehouse deliver the supplies in three days.

Finally realized what Adolf meant by leisure. In the morning, Cassia came back from a secret patrol around the town, sat on a chair and sighed. It's like changing a residence, the only difference is that some freedom is restricted.

The dozen books he brought were read in less than two or three days, and Cassia already had plans to read them a second time. After all, there was no follow-up to the detection incident two days ago, and everything continued to move forward as usual in this quiet and peaceful town. The map has been drawn. Based on the number of steps taken, Cassia basically calculated that the laboratory base is a little more than fourteen kilometers away from this small building and is at the corner of the mountain range.

After checking the map, there were no records of mineral mining around. Cassia guessed that a large part of the underground laboratory base was secretly excavated and built manually. However, there should also be some influence of natural terrain. Otherwise, the depth of more than 300 meters would indeed be It consumes a lot of manpower and material resources.

But it doesn't have much to do with him. The four people here are like air to each other. No one is willing to take the initiative to talk, and the exchange of information is completely out of the question. Adolf only said that if you come here during the mission, you will slowly understand. Three days have passed, but Cassia has not seen anything.

It didn't affect Cassia's condition, and everything probably went according to the established time. In addition to some basic training of simple movements that he insists on every day, in the past day or two, Cassia finally picked up the research and practice of high-frequency sound waves that he had never really done before.

The sudden incident during the detection a few days ago really surprised Cassia. It was like a hidden surprise, which attracted his great attention afterwards. I didn’t expect that after the surgery entered the third stage, I could control myself so easily. Simple convergence of high-frequency sound waves was a problem for Cassia in the past. In the past, sound waves could only be dispersed evenly around, so if you wanted to concentrate the energy, you had to constantly increase the endurance of your throat. But it is much simpler at this time. After it has directionality, the power has been greatly increased with the reduction of consumption.

After recalling all the theoretical information in his head, Cassia finally chose the direction of maximum destruction. The detection of sound wave pulses is enough. I think that the enemy will become more and more difficult in the future. Relying on high-frequency sound waves in the case of unequal information, there is a chance to destroy the opponent's auditory system. As long as there is less than a second, it can cause the enemy's The body's temporary loss of balance is an absolutely fatal opportunity for the enemy.

Moreover, due to the characteristics of high-frequency sound waves themselves, when the power and frequency are sufficient, shattering glass is only the initial manifestation of its power. Afterwards, it can become an invisible attack method in itself, which can bring great pressure to the air. After forming a linear convergence, it can become a shock wave of extremely compressed air suddenly exploding.

At noon the next day, when Cassia was doing basic exercises in the house, there was a sound from the communication machine. The other three people also felt it. When they arrived at the hall, others arrived almost at the same time. As the captain, No. 1 naturally walked over and picked up the receiver.
