The difference between humans and animals is whether or not they can make and use tools.

Therefore, the importance of tools is self-evident, and it can even affect the development and direction of a civilization.

Just like the invention of the magic wand, it made it easier to learn and master magic, and also promoted the prosperity of magic in Europe, so that all kinds of genius spells were born one after another.

For the Native Americans of North America, due to the natural geographical barrier, they have not been able to enjoy the dividends of the wand for a long time.

But correspondingly, they also found a different way, learning to use the skin and blood of magical beasts to cast spells.

Hides and blood, wand-like wood and cores, are also magical.

Based on this spellcasting system, the native inhabitants of the Americas created the Skinshaper, a high-end transfiguration similar to the Animagus.

Of course, compared to the Animagus, the Skinwalker needs to kill, and die in exchange for the power of transformation.

The size of the deformed creatures should also be about the size of the wizard, and this restriction will naturally exclude those who are too small and too large.

But the Animagus can only become a stationary animal, while the Skinwalker can transform into a variety of animals.

Therefore, both kinds of magic have advantages and disadvantages to each other.

However, this kind of academic problem is not a matter of Rove's top priority, and he needs to save people.

The boy checked the Indians again, and after repeated inspections, discussed them with Margaery, and determined that they had been infected with snapdragon toxin.

Snapdragon is also called skull grass.

The two names are very different, stemming from the blossoming and flowering...... The appearance fluctuates greatly.

When in bloom, the snapdragon flowers are particularly beautiful, with a flowing flower shape, like a goldfish swimming in water.

When the flower fails, the snapdragon will form a seed pod in the shape of a terrifying skull with two eyes and a mouth...... It's scary to watch.

And this skull-like seed pod contains chronic poison, and after taking a large amount, the blood will gradually coagulate into lumps.

"Their blood is poisonous, and they need leech therapy to suck it out." Rove looked at Dana and admonished:

"You're going to catch some black leeches, the more the better."

"Good...... Okay, I got it!" Dana nodded hurriedly.

She ran to talk to her people again, but they clearly didn't trust Rove, and they got into an argument.

Rove didn't say anything, just waited quietly, he was just a doctor, it was impossible for someone else to make decisions.

Believe it or not is the other party's business, and it has nothing to do with him.

The quarrel continued until two more clansmen had died, and the Indians came to a consensus and went out to find the leeches.

Taking advantage of the wait, Rove asked Dana to take him to her medicine pantry.

Like Hagrid's cabin, the herbs here are all in the pound, and half of the room is piled up on bitter rice alone, a magical plant endemic to Arizona.

In one cabinet, there are more than 100 plugged vials and countless jars of dried herbs, each with the name of the medicine written on it.

These are the ancestral secret medicines of the tribe.

When Rove was about to leave, he asked Dana for some, and she probably wouldn't refuse.

Of course, the premise is to save her people, and if he fails, he should think about how to take Margaery away. ….

Soon, those tribesmen found black leeches, they were as big as hairy peppers, and their whole bodies were black, and they looked very disgusting.

Rov first treated Dana's younger brother Aru, and he slit the boy's chest with a dagger, and black pus and blood slowly flowed down.

He picked up the leech and poured it on Aru's pale chest, the black leech burrowing into the wound with the blood.

"Prepare another vat for me." Rove continued, "Fill it with piping hot water."

It's not that he's going to take a bath, it's to bathe the black leech...... Black leeches are a double-edged sword that can absorb toxins, but if they can't be eliminated in time, they will also suck the juveniles dry.

It just so happens that black leeches are afraid of high temperatures, and after steaming in hot water for a while, they will emerge from the human body

。

A fire was quickly lit at the door, and when the bath water was boiling, it was poured into the large mahogany bath, and Rove helped the boy into the bathtub.

After soaking for less than three minutes, the long leeches came out of their bodies.

Rove carefully plucked the leeches, and the bugs slowly wriggled between his fingers, they were no longer black, but turned shiny pink after sucking blood.

This thing doesn't need to be pinched to death, you can keep it for the little basilisk as a snack, one bite at a time, sour and refreshing.

Rove, who is a mother, is also conscientious.

After transferring Aru to the bed, Rove gave him another painkiller, and halfway through it, the boy suddenly came to his senses and coughed violently.

The room burst into cheers, cheers, whistles, gasps of horror, whispers of excitement, and...... Dana's cry.

Rovenian wiped the sweat from his forehead and breathed a sigh of relief, if the treatment failed, he immediately took Margaery to run, but fortunately it was successful.

This is how the doctor's profession is, some doctors ask for money, and some doctors are terrible!

Rov treated another person, and he showed Dana the whole process in every detail.

"Alright, you can treat them this way." When Rove finished explaining, he turned and walked out of the room.

Margaery didn't know where to run, so the boy hurried to the village to find her, and finally found her in the northwest corner.

The girl was standing by a well, bending down and looking down.

"You're not going to commit suicide by jumping into a well, are you?" Rove walked up to Margaery and smiled, "If you jump, I won't save you."

Margaery winked and giggled:

"Don't worry, if my sister commits suicide, she will definitely pull you along, and it will be a martyrdom for the two of us, what a poignant death.

Older than me, Zhu Huang died in bed, and you were eaten by magical creatures...... These two ways of dying are much better, aren't they?"

"You're a big-headed ghost!" Rove rolled his eyes.

Margaery reached out and hugged Rove, who was emitting cold air all over her body, as if she was holding a large ice cube, she rubbed it, and said comfortably:

"It's hot, but I'm still holding you to cool down...... What do you think of the poisoned Indians?"

"Someone must have poisoned it." Rove lowered his voice and said:

"Snapdragon is a magical plant from the Mediterranean, rare in North America, and the likelihood of them eating it collectively is too small."

"I just asked Dana, and she said it's the main source of drinking water for their tribe." Margaery stepped on the edge of the well.

"You think someone poisoned here?" Rove frowned and said, "What about the purpose?"

"I think it's for the pyramid." Margaery whispered.

"The floats?" Rove wondered, "There is indeed gold and precious stones on it, and it looks quite valuable."

"No...... I mean what's in the altar at the top of the pyramid." Margaery shook her head.

"What could be there?"

"I've seen Dana's memories." Margaery leaned into Lov's ear and whispered:

"At the top of the Golden Tower is a ...... Quetzalcoatl Egg."
