The water of the river, which had been infused with the dragon's blood potion, soon spread throughout the county of Salon. And although the fact that the river turned red brought a surprise to Elsa and the others, who had already known about it, it did cause a lot of frightening to the soldiers of Turbidity Town and the refugees scattered throughout the county. Fortunately, when the soldiers who had been wounded in battle with the nezumi and contracted the plague inadvertently drank the red river water, and as their diseases were miraculously cured, Leon and Lothar in Turbidity Town also vaguely guessed that it was the work of the cheese.

And then the knights of the kingdom who brought a large number of recovered refugees from the deserted village also confirmed their suspicions a few days later. In short, after the cheese was dosed this time, the condition of the patients in the entire Count of Salon, who had not completely turned into rat people due to the plague, was effectively suppressed. However, as the developer of these drugs, Cheese knew that this would only alleviate the epidemic for a while. The plague viruses were not completely killed by his potion, and as long as he did not find a way to eradicate them, they would slowly mutate until they became terrible disasters once again. And the mage can be sure that this day will not be long, and his potion will only be a temporary expedient measure after all.

On the night of the antidote, Cheese returned to the deserted village, not wanting to spend the night on a deserted snowy mountain with a dragon whose temper had become three times worse than usual because he had been bled out. Therefore, the mage would rather brave the biting cold wind and rush back to the deserted village overnight. Because it was midnight when he arrived at the deserted village, and the river turned red to let everyone know that the mage's plan had succeeded, there were not many people in the village at this time. When the huge red figure landed in a small voice that was completely incomprehensible to its size, the only one who noticed this was the proprietress who had been waiting all night for the mage to return.

When Elsa rushed down the stairs to the outside of the village, she saw a mage and a dragon under the moon. In a midnight sky filled with only sparse stars and a bright moon, all the colors seemed to be a gradient between silver and black. The gray robes turned silver in the moonlight, and the dragon's scales weren't as bright red as they were during the day. Of course, the dragon and the mage also noticed the arrival of the proprietress. Cheese saw that it was Elsa, smiled slightly, and made a small gesture, he didn't want to wake up the whole village.

"I saw that the river was changing color, and you succeeded, right?" Elsa, who ran to the mage, lowered her voice, but was still excited.

Cheese nodded, the successful spread of the potion was a prerequisite for him to leave the county and go to the royal capital to track down the fake baron. If the epidemic situation here is still expanding, the mage can't leave blindly.

"Wait a minute, I'm going to pay Migo this time. The mage stopped the proprietress who wanted to continue talking and said. He turned to face the dragon, and even in the dim moonlight, the red dragon's massive body was still full of oppression.

"So you remember to be paid. Migo whispered, and while it was nice entertainment to admire the awed look on the faces of ordinary people looking at him, the dragon now only wanted to get paid and leave. It's acceptable to be summoned by a mage as a flying tool, but being forced by humans to voluntarily donate blood will make other dragons laugh out of their big teeth if they hear about it.

Cheese can probably guess the reason for Migo's unhappy reaction. In his opinion, although the dragon had lived ten times as long as he did, it was no different from those eleven or twelve-year-old children in terms of mind. Even the fear of pain is the same. Of course, these mages are also thinking in their hearts, no matter what, the dragon still cares about face very much, if the cheese dares to describe it like this, it is not impossible for the other party to tear up the contract in a fit of anger.

"Okay, it's not too early, I want to rest early. Do you want it or not? If you don't talk any more, I'll go back to sleep. Said angrily. Cheese held out his left hand.

Hearing that the mage was going to settle the account, the red dragon quickly stretched out one of his front paws, one of the thumbs of the dragon claw was just under the mage's left hand, saying that it was a thumb, but the thickness of this claw was enough for a small dining table. Seeing the dragon stretch out its claws, Cheese said no more, and took out a knife in his right hand, and slashed the palm of his left hand in Elsa's puzzled eyes, and bright red blood dripped down the wound from the mage's hand to the dragon's claws.

Although she was curious about the conditions under which Cheese hired the dragon, the proprietress never thought that the reward that the mage said was actually her own blood. And as the blood dripped down, a black intricate pattern appeared on the top of the dragon's head, which looked like some ancient symbol. A third of the symbol had turned red, and the rest was still black, albeit faintly, but Elsa observed that the red part of the symbol was increasing at a very slow rate. But soon, the wound on the mage's palm healed spontaneously, and the red-black ratio on the symbol did not change, and gradually faded, and finally disappeared above the dragon's head.

"I'll take the reward this time. Boy, do you remember not to die until you complete our deal. The red dragon retracted his claws as he spoke, and then flapped his wings and flew into the sky without waiting for the mage to reply. Soon, the dragon's figure disappeared behind the night's clouds.

"What's going on? Why did you pay it with your blood?" asked the proprietress holding the mage, who had lost some of his legs from blood loss.

"Actually, it's nothing. Many years ago, Migo sought the help of my teacher for some reason. The teacher sent me to solve this plea, and in return, Migo signed a master-servant contract with me, but that contract was not infinite, and what I did for the dragon was not enough to make it loyal to me for the rest of my life. So we made a pact that every time I used Migo's power, I would use my own blood to erase a part of the contract, and of course it would not affect the validity of the contract. But when my blood was enough to erase the contract, Migo was free. The mage said. Not only because the moonlight was still weak, but his face looked a little pale.

"That's why you didn't call it over to help before?" Elsa asked.

"Sort of. After all, there's one thing I'm not in the right to laugh at Migo. The mage said with a smile.

"Because I'm also afraid of pain. ”
