After repeating this step for four or five times, the precipitate in the cup was getting less and less, and the color changed from white to a faint blue-yellow color.

"Is this done?" Edward asked from a distance, looking at the cup in Ashes's hand.

"To be honest, I'm not sure this vaccine is effective...but the antibiotics have been used up." Ashes glanced across everyone, "As for whether the vaccine is effective, someone has to test it."

...

The person who was finally treated as a test subject was a child who was only nine years old, No. 15 "Seed".

He was born in the quarantine area the second year of his arrival. According to Edward, seeds aged ten to fifteen are the best quality seeds. Although those who have not experienced the day of his arrival also have the possibility of awakening, the probability is much lower than those who survived the day of his arrival.

Under the threat of the muzzle and the temptation of the candy, No. 15 finally sat down in front of the ashes with trembling.

From the reflection in the eyes of No. 15, Ash saw his current image - he was wearing a thick and unfit black robe, a strange-shaped bird's beak mask on his face, and his hair was all wrapped in a piece of black cotton cloth, and the collar and cuffs were tied tightly with ropes... This outfit was exactly the same as the plague doctor before.

Many people regard the plague doctor as the messenger of death, and the bird beak mask with a long beak was regarded as an ominous omen. But in fact, it is these seemingly gloomy and terrifying plague doctors that built the forefront of human resistance to plague.

But there is nothing wrong with it... they are indeed the closest people to Death.

"Relax, don't be nervous." The voice of ashes came from the bird's beak mask, which sounded particularly dull.

He dipped a cotton swab to dilute some vaccines diluted with water, and then applied it to the inner side of the nasal cavity of No. 15 - this is a very ancient vaccination method with a high degree of risk. Even a vaccine that has been proven to be effective, the chances of vaccination are rarely more than 90%.

What's more, the "vaccine" used by Ashes was temporarily produced, and he was not sure about the success rate.

The vaccine will be vaccinated soon, but it will take quite some time to infect the tester and stimulate the tester's own immunity.

On the 15th, it was placed on a simple stretcher, carried by two men in black wearing tight protective clothing, while Ash was carrying a water bag in his hand, ready to pour water on No. 15 at any time. According to medical records, anyone vaccinated with the plague vaccine often had symptoms of high fever, coma and a lot of sweating within a few hours of the vaccination. If the water was not replenished in time, the vaccinated person was likely to have symptoms of dehydration.

Margaret did not continue to delay. After the people in black finished organizing the equipment and supplies, they issued an order to set off and began to move towards the direction away from the palace area.

The only "Sabertooth Tiger Type I" steam tank in the Margaret team was placed at the forefront of the team and undertaken the task of opening the road. Compared with the three "Sabertooth Tiger Type II" that Edward lost in the palace area, the firepower of the Sabertooth Tiger Type I is slightly weaker and the armor thickness is also a certain difference. However, in terms of the ability to clear roadblocks, the Sabertooth Tiger Type I, which uses the same steam engine, is not inferior to its improved type.

The bushes blocking the road were directly crushed by the tank's tracks, and a relatively flat passage was opened up in the ruins of the isolation area.

Perhaps it was because of the blood of the Crazy Beast, or perhaps because of the plague fog, the team was not attacked by any Crazy Beasts during the transfer. Even if they encountered several Crazy Beasts alone, the originally extremely bloodthirsty beasts would choose to escape from them quickly.

After walking in the ruins for almost four hours, we finally arrived at the pre-set first target point.

"Reinhardt University".

Although this academy is named after Reinhardt, it is not the first institution of the old imperial capital. The first is the "Imperial Noble Academy" located near the Imperial Palace District. However, the Baroque building that even though it has become a ruin but still exudes a luxurious atmosphere is probably under the cover of black fog.

Unlike the Imperial Noble College, which only accepts aristocratic children, more than 70% of the students at Reinhardt University are civilians... However, when a student with excellent grades graduated from Reinhardt University, it will not take long for him to get rid of this inferior identity - in the legend of the East, there is a story of "carp jumping over the dragon gate", and this Reinhardt University is the "dragon gate" that is regarded by the vast majority of imperial civilians as able to change their destiny.

After the arrival of the day, due to its strong structure and relatively well-preserved buildings, the ruins of the University of Reinhardt were naturally regarded as one of the settlements by the survivors. However, it is the dark season, and the survivors who gathered in the university site in the morning have to be scattered to other places. Only the strongest small group of survivors can continue to stay here.

There were six survivors left in this place. Although there were not many people, they had several rifled flints that only soldiers could equip. Such firepower was one of the best in the survivor organizations in the isolation area, but in the eyes of Margaret and others, they were not even "threat".

The man in black occupied Reinhardt University without any casualties. All six survivors were shot dead on the spot. Ashes didn't even have time to ask them to leave a few living mouths for testing the vaccine.

The main building and several teaching buildings in Reinhardt have collapsed. However, the dormitory building, which is only three-story, is well preserved. On the 15th, who has been vaccinated with the plague vaccine, was moved to a dormitory by the people in black. At this time, symptoms of infection have begun to appear on his body.

Needless to mention the symptoms of coma and high fever, bright red chickenpox began to grow on the surface of No. 15's body. However, compared with the shocking pustules on the plague-infected person before, No. 15's chickenpox was much smaller in size, and there was no obvious ulceration in the skin.

"This means you succeeded, right?" Margaret said, standing behind Ash. Now, in this dormitory, except for the unconscious No. 15, there are only two people in Margaret and Ash... As for Edward, he naturally hopes that the farther away from this place, the better.

"The situation is relatively optimistic, but I dare not make a conclusion before the final result comes out." Ashes nodded, pried open No. 15's mouth with his hand wearing glue gloves, and poured him a few more mouthfuls of water.

"I have sent scouts to the palace area. He will monitor the movements of the black fog at any time. We will stay in this place for about two to three days. During this period, can you get a sufficiently safe vaccine?" Margaret asked.
