Zheng Yi walked down from the tower and saw Green talking to a few lightly injured explorers, and clapped his hands:

"Sister Blanche, get ready to begin."

Green immediately ran over.

Zheng Yi asked her to bring the water that was boiled and cooled: "Distilled water should be used for debridement, let's deal with it for the time being." He then administered an [anesthesia] to the injured person to temporarily isolate the pain so that he could teach with peace of mind.

Qing creation is one of the six basic skills of surgery, and it has long been played out. If I really want to finish everything, I'm afraid that three days and three nights will not be enough, and there is not enough technical support in this world to buy preparations and equipment.

Tracing back to the source, the core of debridement is to clean the wound, remove necrotic tissue, and allow the body to repair itself.

The deep wound Zheng Yi solved with healing, leaving the flesh wound for Green to practice.

People will be terrified of the trauma of their own kind because of the empathic instinct, and this can only be practiced. That's how doctors come here. Even if you kill a lot of mice, there are many newcomer doctors who have eaten next to the general teacher, and who can't control their fear and vomit when they see fresh wounds.

Zheng Yi said: "Don't hold your breath. It's also important to get used to the smell and, of course, make a mask tomorrow. ”

Human fear comes from sight, hearing, smell and touch, and it is also important for doctors to adapt to the smell of the human body. Especially the smell of bloody gas and tissue necrosis.

Green thought he had seen a lot, but he couldn't help but turn his head and let out a long sigh. She followed the demonstration of the sage just now, rinsed the wound with pure water, and then saw the scalpel handed by Zheng Yi.

"The inactive area should be removed." Zheng Yi demonstrated the gesture of holding the knife and began to decompose.

Generally speaking, the tissues of normal trauma do not deactivate so quickly, but the opponents are all demons carrying various trans energies. The wounds they create are either infected or cursed, and are not so easy to deal with.

Zheng Yi cut off the inactivated tissue of the wound, rinsed it with clean water, and then took out the needle and thread and began to suture.

Suturing is the second basic skill of the surgeon, Zheng Yi from the banana peel, pig intestine, rat tail ...... The skills that have been practiced step by step are excellent, fast and good.

Green was dazzled by the fact that a hideous wound had already been healed.

"Next."

Zheng Yi said: "Scalpel disinfection is very important, I will deal with it today, and I will start to build a special disinfection cabinet tomorrow." At the very least, boil in boiling water for half an hour. ”

Generally speaking, 1-2 minutes in boiling water at 100 degrees Celsius can complete the disinfection, but it takes a long time to kill the spores. Bacillus anthracis spores are boiled for 30 minutes, tetanus spores for 3 hours, and Clostridium botulinum spores for 6 hours.

Zheng Yi couldn't let them disinfect for 6 hours, and the cost performance was too low. It is better to deal with most of the common problems and then to solve them with exorcism when they are made exceptions.

When it came to the third wounded, Zheng Yi was completely handed over to Green to deal with after [anesthesia].

It's nothing more than cutting more when going to rot, or the wound sewn out is not good-looking.

With the guidance of Zheng Yi, a full-time doctor, Green got started quickly. She thought that she would fight like the Rogge sisters, and although she had been training hard, she was always apprehensive. I didn't expect the Sage to let her treat her wounds, and this kind of work is simply a tower down in difficulty compared to fighting.

After more than 20 days of physical training, Sister Green's physical fitness was far from that day, and her physical fitness was enough to support her continuous debridement and suturing.

Because the patient is arranged from heavy to light, the lower the difficulty is the later it is, and Zheng Yi only needs local anesthesia. As for the disinfection, it is exempt, because not everyone will be infected, and besides, it is necessary to let the newcomers know about the infection phenomenon, so as not to be at a loss when he is not there.

The injuries of the Rog girls must be healed immediately. They are the main force of the battle, and if there is a demon sneak attack at night, Blackstone Fort can't even have the strength to defend.

With Green sharing the pressure, Zheng Yi's blue consumption has dropped a lot. He hadn't been too excited after the victory before, precisely because the battle was too blue. Now the loss of the embankment is made up for the outside of the embankment, which makes the most blue-deficient sequence 2 in history much happier.

After Zheng Yi touched and applied [anesthesia], he asked the wounded to pay attention to waterproofing and walked out of the tower.

Outside the tower, the heat was in full swing, and Kashya lit almost all the torches, decorating the Blackstone Castle with a sparkling appearance.

Zheng Yi took out the chocobo and took out the small gifts he brought this time from the side box: five emergency lights, five flashlights, and five binoculars. He needed these small gifts to maintain the prestige of the Blind Sisters and bring more explorers to the system.

More than a dozen Rogers died in today's battle, more than one percent. Because of the relationship between equipment and training, the sacrifice rate of explorers is higher, nearly 30%. If it weren't for the Rogge girls to fight the main force, the explorers would have collapsed long ago.

Such a battle is definitely a "very dangerous" mission.

Zheng Yi handed the small gift to Kasha: "After today, there should be many seventh-order explorers. ”

Emergency lights, flashlights, binoculars, and elven cookies are all items that can be purchased by explorers who have reached "intimacy" in prestige. Very practical, suitable for both the wild and the ability to be used in towns and camps.

Kasha took the present, recognizing the emergency lights and flashlight, but had no idea about the telescope, and flipped through it in his hand. Zheng Yi showed her how to use it, and immediately made her scream.

"Your Excellency, this is simply amazing, it must be left to the lookout!"

"Let's let two out, the price can be higher, but let people know how to use this." Zheng Yi said: "What we need is the Allied Army, not one or two items. ”

Kashya said ashamedly, "You are right, Your Excellency. ”

Zheng Yi took out the chocobo, the new car, which was also towed by Du Bin, and said:

"It's for you."

Kashya almost jumped in surprise:

"To us? For us in the Order? Your Excellency, this is too valuable! ”

Zheng Yi said:

"Blackstone Fort is too far from the camp, and you need faster, more powerful transportation. It can pull bigger carts, and if you can build rails, it can even pull five or six bullock carts. ”

Zheng Yi pulls the cargo with chocobos in Ijuiluvida, which is constrained by the stability of the carriage, not by its weight. If the Rogers can build a railway, it would not be a fool's dream to pull up a train with chocobos. However, according to Zheng Yi's observation, the Sisters did not have the financial and manpower to build the railway.

After all, the world does not even have a steam engine, and in order to promote industrial production, it is necessary to plant seeds from the source.

Zheng Yi didn't have a lot of patience for this, after all, he wasn't one of those revolutionaries.

"As long as you reach the fourth order, admiration, you can buy this mount." Zheng Yi said: "It is necessary to make people greedy. ”

"Yes...... Buy......! "Kasha: It's not a surprise, it's just a surprise.

Zheng Yi nodded and began to think about what kind of price should be set appropriately.
