After a while, Shi Xing and the Northern Evil Old Immortal arrived in the sky above Beiyin City, Shi Xing pointed to the suburbs of Beiyin City and said, "Look! That large factory with an area of 300 acres is our 674 troop detachment, let's go down and have a look." ”

The two of them landed in front of the door called the Ministry of Epidemic Prevention and Water Supply, and the guards standing on both sides of the gate wanted Shi Xing to bow and pay respect, and then Shi Xing and the Northern Evil Old Immortal entered the 674 detachment, Shi Xing pointed to the three buildings in front of him and said to the Northern Evil Old Immortal: "The building in the middle is the office and conference room of me and the other branch heads, and there are also staff lounges, guard offices and diagnosis and treatment rooms, and there are also a lot of arms storage inside. ”

"What about the other two?" asked the Northern Evil Old Immortal.

"The other two buildings on the left are the canteen and the bathhouse and our treasury, and the one on the right is all for us to run the Xuanqi to launch, and the artificial hair transmission style Xuanli is for the hair factory, after all, our 674 unit also has ordinary members. While introducing, Dr. Shi Xing led the Northern Evil Old Immortal to a bungalow in the southwest district, and before he could get completely close, he heard a burst of creepy screams. "Ahhh

"What's going on?" the Northern Evil Old Immortal didn't understand what was going on. And Dr. Shi Xing asked him to go to the house, which covers an area of 50 square meters, with a construction area of 113 square meters, and there are two guards guarding there at the door, and the two guards also want Dr. Shi Xing to bow, and Dr. Shi Xing walked into the room without looking.

Shi Xing and the Northern Evil Old Immortal walked down the aisle, and through the partition glass, they could see that there were no less than twenty people wearing gas masks wearing special gas suits in one of the rooms, and there were no less than five such rooms, and there were many beakers with colorful potions on their experimental tables, and everyone was very serious about what they were doing, and one of them picked up a glass of colorless liquid and walked cautiously inside.

"What are they doing here?" asked the Northern Evil Old Immortal.

"Read on. Dr. Shi Xing said nonchalantly. It can be seen that there are three women who are tied to the chair with their backhands, they are wearing clothes that resemble prison uniforms, there seems to be something written on them, they look languid and listless, their heads are bowed, the 674 member who was holding the colorless liquid just now put the beaker to the mouth of the woman in the middle, but the woman has been trying to avoid the liquid, the 674 member seems to be angry and grabbed the woman's hair with his left hand and raised her head, so he poured the glassful of colorless liquid into the woman's mouth roughly, the woman coughed violently, but the member did not let go until the liquid was completely poured into her mouth before holding the empty beaker and leaving。

"What the hell is this doing?" the Northern Evil Old Immortal continued. Shi Xing didn't answer him, but looked at the woman who was forcibly filled with liquid, and within a minute the woman began to cough violently, not to mention how painful it was, she began to cough painfully, knowing that she began to cough up a lot of blood, she stopped slightly, but she couldn't stop coughing violently.

Then another member of 674 arrived, holding a syringe in his hand, and without looking at it, he injected the same colorless liquid directly into the arm of the woman on the left, and he quickly left the place. The woman on the left also began to cough violently, her expression was quite painful and she was coughing up blood, and a member of the next team, also wearing a hazmat suit, began to collect the blood they had coughed up and collected it into a beaker.

Finally, Shi Xing said to the Northern Evil Old Immortal: "As you can see, we are studying viruses, this is tuberculosis bacteria, once these viruses are developed into biological and chemical weapons, do you know their power?"

The Northern Evil Old Immortal shook his head: "How could I know that this is what you have done." ”

"It can be that an army loses its combat effectiveness in an instant, and these biological and chemical weapons, even if they are cheap, are also quite lethal, and some of the biological and chemical weapons in me can't even be stopped by Xuanli cultivators, so I'll take you to another place to visit." As he spoke, Shi Xing took the Northern Evil Old Immortal to the west, where there was also a bungalow covering an area of 280 square meters and a construction area of 437 square meters.

Shi Xing and the Northern Evil Old Immortal walked in together, there was no isolation glass in it but just an ordinary room, they casually walked into a room and saw that a member wearing a white coat and a mask on his mouth was pouring water on the arm of a person wearing a similar prison uniform by the pool, and the subject with wet arms was taken to another room by that person, Shi Xing and the Northern Evil Old Immortal also followed, there were several refrigeration weapons in that room, but they couldn't go in, and even the members inside were wearing quite thick clothes。

"What is written on the clothes of those subjects?" finally asked the Northern Evil Old Immortal.

"The guy's clothes were Stav 544, and these represent their numbers, and I don't care what they're called, I know they'll never have any names as long as they're my experiments. Just as Shi Xing was talking, there was a burst of screams from the refrigeration room, and it sounded like there were a lot of people screaming.

At this time, a member led a "Staff" out, the "Staff" hands were completely wrapped in ice, 674 members led him into the third room, there was a group of people who were making notes, one by one tempering pool, Shi Xing and the Northern Evil Old Immortal saw that the member took out a wooden stick and kept beating "Staff" on his hands, "Bang Bang Bang Bang ......" after a while of beating "Staff" The ice on both arms was all knocked to the ground, revealing the bruise-purple frozen and dead arms under the ice, but it seemed that the 674 member had used too much force, and without his opinion, he broke several fingers of the man and fell to the ground.

Since the experimented "Staff" had long lost his intuition, he didn't scream at all, and the 674 member put his arm into the tempering pool and began to adjust the temperature of the water, and after a while, the member signaled that the person could take out his arm, and the arm that left the water had dried up, and the recorder on the side recorded indifferently, the devil member grabbed the man's arm and tore it hard, and in an instant, the skin and flesh on the arm were completely torn off, leaving only a bare hand bone arm......

Shi Xing said as he led the Northern Evil Old Immortal to the northwest corner: "Just now, it was because the Tianyun Empire was in that cold Northern Empire, so there were often soldiers who were frostbitten or froze to death, so we had to find a way to quickly treat frostbite. ”

"You still haven't told me what the Sect Master told me to do. The Northern Evil Old Immortal didn't know what Shi Xing said at all, so he asked directly.

"Okay, I'll tell you after you visit this with me. "Dr. Shi Xing and the Northern Evil Old Immortal walked towards the northwest corner.
