A gloomy and weird laughter came from under the bird's beak mask. Yang Yu did not directly make his request, but asked:

"You know, why did I suggest coming here to work with you from the beginning?"

The gloomy laughter combined with the questioning that Yang Yu slowly made was like a sharp knife that instantly penetrated Qingcong's chest, making him unable to know how to answer for a while, and could only fall into deep thought.

Through the mask, Yang Yu's mouth gently raised.

The youth's expression showed that he was stepping into his own rhythm.

Yang Yu put in a lot of effort to practice this gloomy and weird laughter.

He wanted to ask Bai Jin for the trick to make a weird laugh, but found that Bai Jin hadn't made such laughter recently.

Bai Jin has been trying to overcome her awkward personality so far. At this point, Yang Yu doesn't want to deny her efforts. He suddenly intervened and said that he wanted to help her overcome that weird personality, which would seem too abrupt.

After thinking about it over and over again, Yang Yu gave up the strange laughter he learned through Bai Jin.

Instead, we took a different approach, constantly changing our laughter, constantly looking for the crazy and gloomy laughter in our memory, and combining them together, which created the current weird and terrifying laughter.

After receiving unanimous praise, Yang Yu was relieved and bold to use this laughter to hit the deepest fear in others' hearts and defeat their inner defense.

The dark and terrifying bird beak mask reflected in his eyes. He tried to find some tips from Yang Yu, and then suddenly realized that he had no way to see through what the man in front of him was thinking.

After thinking for a long time, Qingcong came to the conclusion that he shook his head and showed his ignorance.

The gloomy laughter sounded again, and Yang Yu continued to ask: "Do you know how to quickly make a drug that meets the expected efficacy without any clues?"

Qingcong squeezed his eyebrows and tried to analyze what kind of answer Yang Yu wanted from Yang Yu's standpoint. After thinking for a long time, Qingcong said in an extremely uncertain tone:

"I think the most important thing is whether there are experimental subjects..."

“Hey hey…”

Yang Yu suddenly burst out laughing scared Qingcong, Qingcong frowned,

"I'm wrong?"

"It's better to say that the answer you said is my ideal answer. I thought you would say the boring answer like 'teamwork', and I understand it very unexpectedly."

Extending his hand wrapped in a white bandage, Yang Yu began to untie the bandage.

"Without knowing nothing, the most important thing to quickly make an effective medicine is not 'team cooperation', but depends on how many experimental subjects can try the medicine.

As long as there are enough experimental subjects, you can quickly capture the effect of each drug trial, quickly select products with fewer side effects, and then find the best ratio among drug with fewer side effects."

After completely untiing the bandage, Yang Yu showed his hand to Qingcong.

The skin on Yang Yu's hand was like a cabbage, revealing the back of his hand covered with blood-red patches. When the green onion saw it, he had goose bumps all over the floor, and he looked away a little unconsciously.

In fact, Yang Yu's body looks like healing is completely dried and rubbed with glue. The red patches on his hands are illusions created by using a cosmetic box extracted from the system. If you don't look closely, it will be difficult to find clues.

In order to prevent the fake wound from being exposed, Yang Yu calmly wrapped the bandage wrapped around his hand back.

"As a wandering potionist, I often use myself to try medicine because no one tried it. The result is that my body has long been riddled with various medicines.

Whether to continue wandering freely and try out the newly developed potions with yourself; or to find a place to settle down and continue to develop potions, I chose the latter.”

Tighten the bandage on his hand, Yang Yu continued as if nothing had happened:

"I have heard a lot about your chamber of commerce. You must have conducted countless experiments behind the scenes of that medicine, and there are also many inhuman human experiments.

This kind of practice of using any means for the sake of interests coincides with me, so I like your chamber of commerce.

With your help, I believe I can develop more potions…”

A small bottle of potion appeared in Yang Yu's hand, and the purple color was somewhat similar to the potion Gordon took out.

Yang Yu held the medicine bottle and shook it in front of Qingcong.

"Actually, I have already prepared several trial products of that potion on my hands, but I have no subject to try this thing.

I only have one request, and now I will provide a slave to show me the effect.

As long as you can help me find a slave immediately as a trial user, I can find a way to help you convince that group of people and let them cooperate with you.

Of course, all the results of the medicine I have in my hands belong to you."

Qingcong frowned, despite the big cake and face, he told him to meet the requirements of the man with the mask and bandage in front of him as much as possible.

However, they only stayed in Sethis for a few months, and did not have as rich background as Tren.

Most of the agents are in the trial stage and have not been used in clinical practice, so the purchase of slaves is also ranked behind.

Thinking of this, Asna's figure emerged in Qingcong's mind.

If Asna is still there, she can use her charm technique to control the weak adventurers without having to spend extra money on slaves and guards.

However, Asna was already killed by the hateful man in that hateful invasion. Even the elders of their family were not shining. Her face was too seriously injured because of the man's fault. She died three days later on the way to relocate...

Shaking his mind to clear his memories, Qingcong once again focused his attention on meeting Yang Yu's requirements.

For the revival of the Chamber of Commerce, Qingcong could not say anything, and there was no such thing as slaves here.

A slightly apologetic smile appeared, Qingcong said:

"Mr. Plague Company is very sorry. Our chamber of commerce has caused many slaves to be damaged due to a series of reasons.

I heard that the medicine you made is very strong, and they are still in a state of half-dead. If you are tortured like this, you may die.

I'm not shirking anything, I just want to say that every time a slave is lost in this extraordinary period, it is a huge loss for us."

Yang Yu, who was standing there, didn't say anything, and quietly watched Qingcong perform by himself.

But just by sticking this way, Yang Yu's black outfit was invisible, bringing huge pressure to Qingcong. As a last resort, Qingcong could only quickly turn to the topic.
