After waiting in the lab base until noon, Professor Mosier came out of the lab with a tired face on his face. Seeing Kasia, Professor Mosier smiled slightly.

"Let's go see something first. But Professor Mosier said, picking up the communicator that was connected to the local radio network inside the base, and called Bennett along. As the passage approached more than a hundred meters, Kasia and Professor Komosier stopped in front of an alloy door. But Professor Mosier skillfully opened the alloy door with the code card, and a wide underground cavity appeared in front of the two of them.

Only the foundations of the cavities have been built, and in some places you can even see yellow-brown underground rocks. The alloy floor bears traces of hastily transferred machines, and at the bottom of the cavity, an improvised experimental platform has been erected, where several machines with no discernible age or new age are placed. Next to it was a huge table that had been spliced together, on which, in addition to the necessary documents and papers, Kasia saw various potions that had been carefully packed.

While observing, Bennett arrived with a thick stack of papers, and after greeting, the three of them entered the cavity and sat down on the edge of the table.

"Some of the medicines you need will have to wait for a while, and it is expected to be half a month. The theoretical knowledge related to sound waves is simple, there are many, many in the database, according to your needs, plus the help of a few old friends, it will be quickly filtered out. ”

"It's all information. But Professor Mosier took the stack of papers from Bennett's hand and pushed it to Kasia, "This cavity is the site of our experiment, it's a little rudimentary, but it won't affect anything. During the break, you can sit here and read the materials. If you have any questions, Bennett and I can answer them for you. The direction of research is purification and separation, but our initial direction is to use sound waves to achieve this purpose. However, the performance of the machine and equipment could not keep up, so I chose another direction. Therefore, the knowledge of sound waves is still well understood. But when it comes to difficult questions, you don't have to worry, just bring them up. There are several relevant experts in the organization, and when the time comes, they will send the questions to you and answer them for you. ”

But Professor Mosier said, "The first test is this afternoon, get ready." We also need a little bit of a run-in between us. This venue is enough for you to play without worrying about breaking anything. ”

After a little chat, Professor Mosier received a phone call and left with Bennett. Kasia began to look at the materials. It's really different from what I bought, and it's a lot more esoteric. Even though there is a lot of grounding in sound waves, the speed of reading slows down rapidly after it.

"Sure enough, some of the core materials don't appear directly in the books on the market. Kasia looked at it and sighed. It wasn't until 3 p.m. that Professor Mosier and Bennett were pushing a whole cart of things, and another monitoring machine came over to start the experiment.

Kasia had no idea what the process was, but Professor Mosier didn't explain it, and he didn't ask. The content of the assistance has long been known, and it is up to standard in terms of strength and stability, but it is uncertain how long it will last.

After that, every two or three days, Kasia would go to the lab base to assist Professor Komosier in his experiments. The standard continues to increase with each assist, and the intensity and stability require more and more effort for Kasia to improve and control. These materials played a huge role during this period, and the various methods of use and the interpretation of the principles made Cassia more and more proficient in the use of high-frequency sound waves in the future.

After several experiments, Kasia was able to conduct high-frequency sound beams up to 100 meters away without dispersing. The diameter also goes to about 20 centimeters, and with the blessing of huge energy, the high-pressure air beam formed by the pressurization of the air by high-frequency sound waves at this moment can be called an air cannon. The power is not as strong as ordinary steel-hulled bombs, but the gap is not very large. The power of a depression in the impact of a rock formation is enough to pose a great threat to many enemies in battle.

Half a month later, the pharmacy arrived in the laboratory without incident. He was accompanied by several other professors who answered difficult questions about sonic waves, as well as several surgical project development manuals for reference. Kasia returned with the potion and instruction book, and began to develop the corresponding surgical project on the same day, testing whether the medicine would still work on him.

On the other side, Waters and Dya were going about the things that Kasia had arranged in an orderly manner. On Hesley's side, the matter that Kasia discussed with him also entered the stage of actual operation. According to the country where the stronghold belongs, the list of mercenaries and bounty hunters who are well rated and of decent strength has arrived in his hands a few days ago.

Because if you want to get a suitable job, in addition to looking for middlemen to do this kind of business, or some introducers, you rely on your own fame. So the information of these mercenaries and bounty hunters is very easy to get their hands on. And specially commissioned a professional to do it, and the level of detail of the information made Hesley very satisfied.

Screening was underway, and Hesley proposed a simplified version of the criteria from the Webley family's private army to base it on, along with certain mission records that could be found by the mercenary bureaus and bounty hunters, to make a preliminary hierarchy of these people.

In addition, Hesley also commissioned a number of middlemen and full-time introducers, and provided them with some false fabricated tasks, so as to obtain a large amount of information. The price was nothing more than some employment fees, and Hesley didn't care at all. The sum of the information between the two became a database for Hessler's sifting.

In less than a week, the basic screening was completed. But that's just the first step, and there's a lot more to come. Heslie himself focused on personal strength, and the standards given by Kasia were relatively high. Once these people have been screened, the next step is to search for any geographical location, trying to find some powerful surgeons to invite into the influence. That's the focus of this work. The environment of a small country is not as good as that of a gray region, but it can still give rise to the people Hesley and Kasia want.

"Is it convenient to speak?"

"There was no one around. This side answered.

"As agreed, now I ask for your help. In terms of content, it's about killing a mid-stage five-stage surgeon. The first is to ensure a smooth completion, and the second is to be secretive, so only one person from my side will participate in the necessary personnel. ”

This side did not answer immediately, showing that it was surprised by the blunt words, "Is it just recently? Or do you just want to inform me that I have such a plan and need to be mentally prepared for the future?"
