Waiting until noon in the laboratory base, Professor Mosil walked out of the laboratory, his face full of fatigue. Seeing Cassia, Professor Mosil smiled slightly.

"Go and see something first." Professor Komosil said, while picking up the communicator that connects the local radio network inside the base and calling Bennett. As the passage walked nearly a hundred meters away, Cassia and Professor Komosil stopped in front of an alloy door. Professor Komosil skillfully opened the alloy door with a password card, and a wide underground cavity appeared in front of the two of them.

The cavity was only constructed by the foundation, and even brown underground rocks could be seen in some places. The alloy floor was left with traces of hasty transfer of various machines. At the bottom of the cavity, a simple experimental platform had been built, and several machines with no age or newness were placed there. There was also a huge spliced ​​table next to it. In addition to the necessary documents and papers, Cassia also saw various medicines carefully loaded.

While observing, Bennett rushed over with a stack of thick documents. After saying hello, the three of them entered the cavity and sat at the edge of the table.

"The medicine 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 very simple. There are many in the database. According to your needs and the help of a few old friends, it will be quickly screened out."

"These are all information." Professor Mosil took the stack of documents in Bennett's hand and pushed them to Cassia. "This cavity is the site of our experiment. It is a bit simpler, but it will not affect anything. During normal rest, you can sit here to read the information. Bennett and I can answer the questions for you. The research direction is purification and separation, but our initial direction is to use sound waves to achieve the goal. But the performance on the machine and equipment cannot keep up, so we choose another direction. So we still have a lot of knowledge about sound waves. However, when it comes to difficult questions, you don't have to worry, just raise them. There are several relevant experts in the organization, and then send the questions to you and answer them uniformly."

But Professor Mosil said as if he introduced the situation, "The first trial was this afternoon, and we were ready. We also need a little bit of running-in between us. This venue is enough for you to play, so you don't have to worry about destroying anything."

After talking, he chatted for a while, but Professor Mosil then received a contact and left Bennett. Cassia began to read the information. It was indeed different from what he bought, and it was much more profound. Even though he had a lot of foundation in sound waves, his reading speed slowed down quickly afterwards.

"Sure enough, some core information will not appear directly on the books on the market." Cassia sighed as she looked. It was not until three o'clock in the afternoon that Professor Mosil and Bennett pushed the whole cart, and another surveillance machine came over and officially started the experiment.

Cassia had no idea what the test was, but Professor Mosil did not explain it, nor did he ask. The content of the assistance had long known that both strength and stability reached the standard, but the uncertainty was just how long it could last.

In the following time, every two or three days, Cassia would go to the laboratory base to assist Professor Komosil's experiments. The standards continued to increase through repeated assistance, and Cassia would spend a lot of energy to improve and control in terms of strength and stability. The data played a huge role in the period, and various application methods and principle interpretations made Cassia more proficient in the use of high-frequency sound waves later.

After several tests, Cassia was able to conduct high-frequency sound beams to a distance of 100 meters without dispersing. The diameter also went to about twenty centimeters. With the support of huge energy, the high-pressure air beam formed by high-frequency sound waves pressing the air can be called an air cannon. The power is not as powerful as an ordinary steel shell bomb, but the gap is not very large. The power of a depression at the impact of the rock layer is enough to pose a huge threat to many enemies in battle.

Half a month later, the drug arrived in the laboratory successfully. Several other professors came with answers to difficult questions on sound waves, as well as several surgical project development instructions for reference. Cassia returned with the drug and instruction manual, and began to develop corresponding surgical projects that day to test whether the drug was effective for him.

On the other hand, Waters and Delja were carrying out all the things arranged by Cassia in an orderly manner. On the Hesley side, Cassia discussed with him also entered the actual operation stage. According to the country where the base is located, the list of mercenaries and bounty hunters with good evaluation and affordable strength has been put into his hands a few days ago.

Because I want to receive a suitable job, in addition to looking for middlemen in this kind of business or some introducers, I rely on my fame. Therefore, the information about these mercenaries and bounty hunters is very easy to get. And I specially entrust professionals to do it, and the detailed information is satisfied with Hesley.

Screening is underway, and Hesser proposed a simplified version of the criteria from the private army of the Webley family to use as a basis, and combined with the records of certain tasks that the hiring bureaus and bounty hunters can find, together with the preliminary classification of these people.

In addition, Hesley also entrusted many middle-aged merchants and full-time introducers to provide them with some false fabricated tasks to obtain a large amount of information and information. The price was just some employment fees, which Hesley didn't care at all. The sum of the information of the two became Hesley's database of screening.

In less than a week, the screening was basically completed. But this is just the first step, and there are still many more work below. Hesser himself focused on personal strength, and Cassia gave relatively high standards. After screening these personnel, the next step is to search without restricting regional areas, and strive to find some powerful surgeons to invite them into the power. This is the focus of this work. The environment of a small country is not as good as a gray area, but it can still give birth to the candidates Hesser and Cassia want.

"Is it convenient to speak?"

"No one around." answered here.

"According to the original agreement, I am looking for your help. The content is about killing a mid-stage five-stage surgeon. One is to ensure smooth completion, and the second is to be secretive, so there is only one person on my side who is necessary to participate."
