The corpse fell to the ground, and the body instinctively twitched for more than a dozen times before stopping.

Without caring about the blood dripping in his hands, Cassia stepped to the door a few steps and pulled the door. After the sound detection echoed around him several times, she felt relieved. The control was very good, and the extremely short movement did not wake up the resting staff around him. Several people were alert, perhaps because they were from the captain, so they did not take action.

After taking back the tactical knife, Cassia wiped the blood with the curtains, and then sat on the stool next to her to rest. Unfortunately, only wine was seen in the room, without the warm water that Cassia liked.

Pigu's blood quickly filled the large floor. Cassia sat for a while and then stood up and lifted the body to put it on a chair. By the way, Freeman "sitted" from the bed.

Originally, Cassia wanted to deal with some of the resting surgeons first, and then go to the main control room. But at that time, Pigu had already come out to wander around the air defense base, so Cassia had to retreat and go downstairs and wait in the corridor. After the support team of the air defense base arrived, the number of people was indeed a bit too high. It took a lot of time to solve them all in the form of assassination. It was relatively simple to rest, and the patrols were extremely troublesome. The time difference needed to be considered, and no movement could be transmitted into the ears of others.

If you don't care that the news of the attack here is transmitted back to the mine, it is only a question of whether the bullets can be used. At present, Cassia believes that he does not have that energy. The bigger reason is that for insurance, the patrol teams report their respective situations at a time node within ten minutes, and the time points are not unified and they are staggered, which is tantamount to finding no opportunity.

After looking at the time, I started to act and it was not a moment in the morning, but now I have only less than fifty minutes left for myself.

"After ten minutes, more than thirty people were solved. Although they were all surgeons, they were also the best batch to solve at present." According to this progress, after considering other factors, the remaining time was definitely not enough. The idea of ​​continuing assassination was immediately abandoned by Cassia.

"It needs to be faster and a large-scale attack method, and it is also necessary to ensure that the news cannot be transmitted back to the mine. Otherwise, the plan to go back to the mine in a few hours will be difficult to carry out with Evan and the others." Sitting on the chair, Cassia looked at the enemy's body with blood flowing out of her jaw on the opposite side, and subconsciously touched the syringe tied to her body.

"Casia's black blood is definitely not as effective as the used up of the concentrated dragon blood." Casia, who was talking to herself, was not worried that anyone would notice the movement here. All the actions of the remaining personnel at the air defense base became instant images and existing in his head. "I should have tried it before." Only then did I remember something that was not sure whether the duration of his own scale state would change due to the differences in dragon blood.

Without thinking about this issue, Cassia recalled the low-frequency sound attacks that were often used in the Tusini area. Based on the original effect and the strength of the affected people, she quickly came up with a period of time that she was more satisfied with.

There are both ordinary people and surgeons in the air defense base. If you want to affect them at the same time, you must insert another low-frequency sound wave at a more suitable time node. The rest is also to shorten the time. The practice and improvement of sound waves used as attack methods Cassia has never been lost, but even now, Cassia does not have the confidence to make everyone lose their combat effectiveness within ten minutes due to the influence of sound waves.

Ten minutes are obviously too long for Cassia, which will definitely arouse the vigilance of the rest of the people. Both of them, as the leader in the air defense base, have turned into corpses. When others notice the abnormality, they will definitely report the situation and seek the next instructions and orders. Once the contact is taken, whether it can be connected or not, the result will be exposed, and the abnormality will become a radio signal to the mine at the next moment.

Having already had a response plan in his mind, Cassia thought about the whole plan, got up and went to the control of the air purification system in the room, adjusting the temperature to the maximum. The skin began to receive the temperature signal in real time. After the temperature of Freeman's body could be suppressed by the temperature in the room, Cassia's muscles contracted. In less than a second, the visible skin was already covered with dense black patterns. In one breath, delicate black scales like art pierced out from under the skin, tightly fitting one by one, covering Cassia's body.

"Ah,,," the involuntary breathing sound was like a new life, or a long-lost unlimited liberation of the body. An extremely comfortable feeling came from every part of the body, which could not be described as this feeling. The body purely believed that this was the original self.

The rising body temperature became hot with breathing. Cassia stood by the window, and felt more sensitively. The capture of sound made the entire air defense base several times clearer than the previous detection. The scales in her throat vibrated with the uncaptured sound waves. Invisible things carried extremely strong energy at this moment, penetrating obstacles and covering everyone inside the air defense base.

"It can reduce the time by half, about five minutes." The brain who didn't know where this state got the calculation basis and data, a strange voice told Cassia in this way.

"Now I just hope that Vimer and the others will listen carefully and not follow up without authorization." Having not used low-frequency sound waves in a scaly state, Cassia did not know what effect it would cause and whether it would further cause serious damage to the various organs of the body. It is still in the experimental stage.

It is not worse than the results in Tusini area, and Cassia can judge this. At least he clearly remembers that when he first saw the real dragon, it was in the gray area of ​​the empire - the Bulino area. The dragons reborn from the skeleton fossils went from the underground station to the ground. After flying into the sky, an invisible sound wave detonated all the acidic platinum bullets around the station.

It was still too simple to use it, Cassia thought. He kept staring at the mechanical watch. Soon three minutes passed, and most of the surgeons responded in the feedback information. At this time, he turned around and left here, and another sound wave that was also effective for ordinary people began to be inserted into the sound wave.
